Sitting By Designation, Judge Albright Pens First Federal Circuit Opinion Vacating PTAB Decision for Failing to Consider Petitioner’s Reply Brief Claim Construction Arguments

by Dennis Crouch

The Federal Circuit’s 2023 decision in Axonics, Inc. v. Medtronic, Inc. marked an important change in inter partes review procedure, ensuring petitioners have an opportunity to respond patentee’s newly proposed arguments, with the hope of discouraging patent owners from holding-back (“sandbagging”) at the institution stage.  Case-in-point is the Federal Circuit’s recent Apple v. Omni MedSci decision authored by Judge Alan D. Albright sitting by designation.

Federal Circuit Limits Defendant Attorneys’ Fees Awards for IPR Expenses

by Dennis Crouch

The Federal Circuit’s recent decision in Dragon Intellectual Property LLC v. DISH Network L.L.C. affirms the district court’s grant of attorneys’ fees to the successful defendants, while denying recovery of fees incurred solely in the IPR proceedings and from plaintiff’s counsel.  The case offers important legal conclusions for attorney fees in cases that involve both district court and IPR litigation.

The district court found the case exceptional under § 285 due to the substantive weakness of Dragon’s infringement position, including clear prosecution history disclaimer precluding infringement by the accused products. A key issue on appeal was whether § 285 allows recovery of fees incurred in parallel IPR proceedings. The majority held that when a defendant voluntarily pursues an invalidity challenge through IPR, the fees incurred solely in the IPR are not recoverable. The court distinguished the facts from its prior decision in PPG Industries v. Celanese Polymer, where the defendant’s participation in reissue proceedings was not optional because the plaintiff had initiated them.

The majority also held that § 285 does not permit prevailing defendants to recover fees from plaintiff’s counsel. The statute’s silence on counsel’s liability, in contrast to other statutes and rules explicitly allowing recovery from attorneys, indicated that Congress did not intend § 285 to extend liability to counsel.

However, Judge Bencivengo, sitting by designation at the Federal Circuit, dissented in part, arguing that in exceptional cases based on the complaint being objectively baseless from the start, district courts should have discretion to award defendants all reasonable fees, including those incurred in an IPR that resolved invalidity defenses asserted in response to the baseless complaint. The dissent viewed the IPR as a substitute for the stayed district court litigation on invalidity, rather than a truly parallel proceeding.

While 35 U.S.C. § 285 does not permit holding plaintiff’s counsel jointly and severally liable for attorneys’ fees, other statutes and rules may allow for the recovery of fees from attorneys in certain circumstances.  In this case the court specifically points to two examples:

  1. 28 U.S.C. § 1927, which states that “[a]ny attorney . . . who so multiplies the proceedings in any case unreasonably and vexatiously may be required by the court to satisfy personally the excess costs, expenses, and attorneys’ fees reasonably incurred because of such conduct.”
  2. Federal Rule of Civil Procedure 11, which “expressly allows the court to impose monetary sanctions on attorneys and law firms, which can include ‘all of the reasonable attorney’s fees and other expenses’ incurred as a result of sanctionable conduct.”

The court notes that these statutes and rules “explicitly allow parties to recover costs and fees from counsel” and are “more appropriate vehicles to recover fees from counsel” compared to § 285, which is silent on the issue of counsel’s liability for fee awards.

Codifying Discretionary Denial of IPR Petitions

by Dennis Crouch

The USPTO recently released yet another Notice of Proposed Rulemaking (NPRM) — this one focusing on codification of IPR/PGR rules associated with non-merits based “discretionary denials” of institution as well as termination due to settlement.  This is a controversial area because of that word ‘discretion.’  Unrestricted discretion by government officials is concerning because of the potential for arbitrary or biased decisions, lacking transparency and accountability.  In that frame, these rules are beneficial because they structure and limit discretion – hopefully making the outcomes more predictable and justifiable.  A key note – the rules here focus primarily on procedure (separate briefing for discretionary denials) and substantive issues relating to parallel, serial, and cumulative petitions. Although this is an important step, they do not address discretionary denials associated with parallel litigation (or other outside factors) under Fintiv and subsequent director guidance. This is likely the most controversial area of discretionary denials that is being left out for now.

Congress clearly intended the USPTO to have substantial discretion (more…)

Petitioner’s Failure to Argue that Prior Art was Analogous to Challenged Patent Results in Reversal of IPR Decision

By Chris Holman

Sanofi-Aventis Deutschland GMBH v. Mylan Pharms Inc., 2023 WL 3311549, — F.4th — (Fed. Cir. May 9, 2023).

The “analogous arts” test is used in patent law to determine whether a particular reference is relevant for the purposes of an obviousness analysis. Under this two prong test, a reference is relevant if it is from the same field of endeavor as the invention at issue, or if it is reasonably pertinent to the problem the invention is trying to solve.  In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004)

In its 2007 KSR v. Teleflex decision, the Supreme Court ruled that the obviousness analysis should be more flexible and not confined to rigid rules or tests. Rather, KSR emphasized an “expansive and flexible approach” to obviousness.  While KSR did not directly address the analogous arts test, it could be interpreted as calling for a more flexible approach allowing courts and the PTO more leeway to consider prior art from a broader range of sources as being “analogous” or “reasonably pertinent,” which in principle should make it easier for challengers to invalidate patents.

In inter partes review (IPR) proceedings, the Patent Trial and Appeal Board (PTAB) has invalidated patents claims for obviousness based on cited prior art that the PTAB found to be analogous, and until now the Federal Circuit has consistently affirmed those decisions on appeal.  Unwired Planet, LLC v. Google Inc., 841 F.3d 995 (Fed. Cir. 2016); Smartdoor Holdings, Inc. v. Edmit Indus., Inc., 707 F. App’x 705 (Fed. Cir. 2017); Toyota Motor Corp. v. Reactive Surfaces Ltd., LLP, 816 F. App’x 480 (Fed. Cir. 2020); CyWee Grp. Ltd. v. Google LLC, 847 F. App’x 910 (Fed. Cir. 2021); and Kamstrup A/S v. Axioma Metering UAB, 43 F.4th 1374 (Fed. Cir. 2022)).

On occasion, the PTAB has found cited prior art to be non-analogous, and thus irrelevant for purposes of the obviousness inquiry.  The Federal has twice affirmed those decisions on appeal.   Polygroup Ltd. MCO v. Willis Elec. Co., Ltd, 759 F. App’x 934 (Fed. Cir. 2019) and Broadcom Corp. v. Int’l Trade Comm’n, 28 F.4th 240 (Fed. Cir. 2022)).  In one reported decision, Donner Tech., LLC v. Pro Stage Gear, LLC, 979 F.3d 1353 (Fed. Cir. 2020), the Federal Circuit vacated and remanded after concluding that the Board had applied the wrong standard when it determined that a cited prior art reference was not analogous art.

On May 9, in Sanofi-Aventis Deutschland GmbH v. Mylan Pharms. Inc., the Federal Circuit held for the first time (to the best of my knowledge) that the PTAB erred in finding cited prior art to be analogous in an IPR.  Significantly, the Federal Circuit’s decision did not address the merits of the analogous art question, but instead was based entirely on the fact that the patent challenger (Mylan) had failed to allege that the cited prior art was analogous to the challenged patent (U.S. Patent No. RE47,614, which relates to pen injectors used for the delivery of drugs such as insulin).

The court observed that:

A petitioner is not required to anticipate and raise analogous art arguments in its petition; instead a petitioner can use its reply to “respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.” See 37 C.F.R. § 42.23. However, Mylan did not use its reply to explain how de Gennes is analogous to the ‘614 patent.

The court reversed the PTAB’s finding of nonobviousness because it had relied upon a finding that the de Gennes reference was analogous prior art, but Mylan had never made the required analogous art argument. Mylan argued on appeal that it had, in its IPR petition, effectively argued that the de Gennes reference was analogous to another other cited prior art reference, i.e., Burren, and that Burren and the challenged Sanofi patent address the “same problem.”  However, the court found Mylan’s arguments as to Burren insufficient to carry its burden because they did not directly address the challenged patent.

The court explained that:

In evaluating whether a reference is analogous, we have consistently held that a patent challenger must compare the reference to the challenged patent. This conclusion is reinforced by the purpose of the analogous art test, which is to examine whether a reference can be considered as prior art to the challenged patent in the first place. [The] purpose of the “prior art” must be evaluated with reference to the inventor’s purported invention disclosed within the challenged patent.

 

Claim Construction and Due Process: Examining NST Global v. Sig Sauer Inc. in the Supreme Court

by Dennis Crouch

NST Global, LLC, dba SB Tactical v. Sig Sauer Inc. (Supreme Court 2023)

This case has a low chance of being granted certiorari, but it still has some interesting elements regarding claim construction and procedure.  This is a perfect case for the Supreme Court to issue a GVR (Grant-Vacate-Remand) with an order to the Federal Circuit to explain its reasoning.

The setup is common. Tactical sued Sig Sauer for patent infringement; Sig Sauer responded with an IPR petition that was eventually successful.  Tactical appealed based upon the PTAB’s sua sponte claim construction that found the preamble to be limiting, but the Federal Circuit Affirmed without opinion.

The Supreme Court petition asks three questions:

  1. Whether the claim construction finding the preamble limiting was improper.
  2. Whether the PTAB violated due process by construing the term sua sponte and failing to give the patentee with notice or an opportunity to present evidence.
  3. Whether the Federal Circuit’s use of Rule 36 violates constitutional guarantees  of due process and the statutory protections of 35 U.S.C. 144.

The Tactical patents cover a forearm stabilizing brace that can be attached to a pistol. U.S. Patent Numbers 8,869,444 and 9,354,021. Sig Sauer initially was a distributor of Tactical’s product, but later began making its own competing product. At that point Tactical sued.

In the IPR petition, Sig Sauer did not request any claim construction. Likewise, the petition decision granting the IPR stated that no claim terms needed any express construction.  “We agree—we need not expressly construe any claim term
to resolve the parties’ dispute.”  During briefing, neither party requested construction of any aspect of the claim preambles.  Eventually though, in its final written decision, the PTAB interpreted the preambles as limiting and then used that construction to conclude that the claims were invalid as obvious.

Yes, I said that the narrow construction led to the claims being found invalid.  That is unusual — usually the addition of limitations helps to avoid the prior art. In this case though the focus was on objective indicia of non-obviousness. NST’s sales; copying by Sig; praise; etc.  But, by giving weight to the preamble terms, the PTAB was able to destroy the presumed nexus between the claims and NST’s product.  The result, those secondary indicia were found wanting because NST had not provided additional evidence “commensurate with the claims” as newly construed.

For context, the claims are directed to the attachment, but the preamble recites “a handgun” and “a support structure extending rearwardly from the rear of the handgun:”

1. A forearm-gripping stabilizing attachment for a handgun, the handgun having a support structure extending rearwardly from the rear end of the handgun, the forearm-gripping stabilizing attachment, comprising: . . .

The PTAB ruled that the claims require the handgun and also the support structure  as recited in the preamble along with the forearm attachment described in the body.  The problem for the patentee is that its objective indicia evidence focused on the forearm attachment, not the whole package.  Thus, no nexus and no weight given to those secondary factors.  In its decision, the PTAB when through the whole life and meaning analysis: “we conclude that the preambles of claims 1, 3, and 5 are ‘necessary to give life, meaning, and vitality to the claim[s],’ and, as such, are limiting.”

The case was already close because there is a long history of this sort of stabilizer going back to the 19th Century, and so the absence of secondary considerations led to the obviousness conclusion.

During the IPR trial, Sig Sauer had argued that the high sales were due to an odd regulatory scheme against semi-automatic rifles, and the pistol attachment was actually popular primarily because it allowed the pistol to be shouldered.  On appeal, that was raised as an alternative justification for the judgment. But, in my view, the PTAB did not actually rule on that issue in the first place.

The patentee appealed, but the Federal Circuit panel of Judges Reyna, Schall, and Chen affirmed without opinion.

Laundry Lists of Components are Insufficient Written Description for a Particular Combination

by Dennis Crouch

The pending Supreme Court case of Amgen v. Sanofi focuses on a broadly claimed genus and asks whether the disclosure is sufficiently detailed.  The Federal Circuit’s recent UMN v. Gilead is the flip-side.  Regents of the U. of Minnesota v. Gilead Scis., Inc., 2021-2168, — F.4th — (Fed. Cir. Mar. 6, 2023).  UNM’s original disclosure is extremely broad with “laundry lists” of components that might be included in various combinations;  while the later-added claim is directed to a more particular sub-genus combination.  The court looked in vain for some indication in the specification as to why the claimed combination is important or particularly suggested.  Here, they disclosed a large forest, but failed to disclose the tree that turned out to be valuable.

Going forward, a patentee might avoid this particular problem with some patent attorney tricks.  Rather than listing all potential components for each functional group and generally suggesting their combination, an early-stage patentee might have its AI assistant provide a hypothetical example of each possible combination, one at a time.  That situation would provide clear ipsis verbis disclosure and thus more likely survive a written description challenge.

= = =

Most U.S. patents assert priority to at least one prior patent application filing.  The early filing date helps avoid would-be intervening and invalidating prior art.  But, the right to priority is not automatic. In addition to the formal paperwork, the original application must sufficiently disclose the invention as claimed in the later patent.  Sufficiency of disclosure is generally judged under 35 U.S.C. §112(a) with the doctrines of enablement and written description.

A patent that improperly claims priority is not automatically invalid.  Rather, the priority filing date is rendered void and then we consider whether the  invention was still novel and nonobvious as-of the later filing date.  This setup also allows these disclosure issues to be considered during Inter Partes Review  (IPR) proceedings that are statutorily limited to anticipation and obviousness grounds.

 

In Regents of the U. of Minnesota v. Gilead Scis., Inc., 2021-2168, — F.4th — (Fed. Cir. Mar. 6, 2023), the Federal Circuit faced the issue of whether the  written description found in UMN’s priority applications supported the claims in the resulting US8815830 patent.  Here, the ‘830 patent covers the drug sofosbuvir that has FDA approval for Hep-C treatment.  Claim 1 does not simply cover sofosbuvir, but instead an entire genus of molecules that fit the general structure shown above and where functional groups R1 – R7 are further defined within the claim.  For instance, “R3 is hydroxy … R5 is an amino acid …”

UMN’s initial patent application was a provisional filed back in 2004, followed by a PCT application in 2005, followed by a non-provisional application in 2007 and finally by another non-provisional application in 2013 that led to the ‘830 patent. In 2010, a Gilead patent application published (“Sofia”) that discloses the claimed invention.  In this setup, UMN’s can disregard Sofia so long as it properly claimed priority to at least one of those earlier applications.  But, if priority fails then the ‘830 patent is anticipated.

During the IPR, the Board sided with Gilead — concluding that the priority filings lacked sufficient written description and thus that the claims were invalid as anticipated. On appeal, the Federal Circuit has affirmed in an opinion by Judge Lourie and joined by Judges Dyk and Stoll.

The patent act requires a “written description of the invention” be submitted in the form of a patent specification.  “Judicial gloss” explains this requirement has proving that the inventor “possessed the invention as claimed” at the time of filing.  Written description issues most often arise in situations like this one where the patented claims were not found in the original filing documents; but rather were added later during prosecution.

The courts have been particularly hard on patentees seeking to claim coverage for a large genus of compounds.  In that situation, it is typically a difficult endeavor for the patentee to literally enumerate all operable compounds covered by the claims.  That level of disclosure is not required, but the patentee must describe “the outer limits of the genus” as well as “either a representative number of members of the genus or structural features common to the members of the genus, in either case with enough precision that a relevant artisan can visualize or recognize the members of the genus.”  The court will also consider “blaze marks within the disclosure that guide attention to the claimed species or subgenus.” Slip Op., citing In re Ruschig, 379 F.2d 990 (CCPA 1967).

Ipsis verbis: I mentioned above that written description challenges are most often successful in situations where the claim scope has changed during prosecution.  Claims that are found word-for-word in the original application (ipsis verbis) can still fail the written description requirement, but that result is much less likely.  Here, UMN argued that the original provisional filing disclosed the eventual claim in ipsis verbis form — pointing to a combination of elements of provisional claims 1, 2, 13, 21, 22, 45, and 47 that collectively forming a substantial word-for-word recitation of claim 1 in the ‘830 patent.  On appeal though the Federal Circuit found that combination of this disparate set of claims required a bit too much cleverness.

Following this maze-like path, each step providing multiple alternative paths, is not a written description of what might have been described if each of the optional steps had been set forth as the only option. This argument calls to mind what Yogi Berra, the Yankee catcher, was reported to have said: “when one comes to a fork in the road, take it.” That comment was notable because of its indeterminacy, its lack of direction. Similarly, here, all those optional choices do not define the intended result that is claim 1 of the ’830 patent.

Moreover, Minnesota’s argument is akin to that rejected in Fujikawa, where the applicant “persist[ed] in arguing that its proposed count [wa]s disclosed ipsis verbis in Wattanasin’s application.” Fujikawa v. Wattanasin, 93 F.3d 1559 (Fed. Cir. 1996). As the court explained in Fujikawa: “just because a moiety is listed as one possible choice for one position does not mean there is ipsis verbis support for every species or sub-genus that chooses that moiety. Were this the case, a ‘laundry list’ disclosure of every possible moiety for every possible position would constitute a written description of every species in the genus. This cannot be because such a disclosure would not ‘reasonably lead’ those skilled in the art to any particular species.”

Slip Op.  I would argue that the Federal Circuit erred on this point. The UMN provisional application’s Claim 1 is directed to the same general molecule, but with much broader definitions for each of the functional group. Then, the subsequent provisional dependent claims (2, 13, 21, 22, 45, and 47) refine the scope of those functional groups in a manner that is identical to that eventually claimed in the ‘380 patent.  Here, each of these dependent claims are defined as being dependent upon any of the prior claims.  Thus, provisional dependent claim 47  seemingly includes the identical limitations found in the ‘830 patent claim 1. Yes, it is a little bit complicated, but so is chemistry.

It is not clear that my quibble would change the outcome of the case since ipsis verbis support does not necessarily result in sufficient written description.

= = =

The absence of ipsis verbis support is not fatal, so long as the original filings sufficiently show possession of the full scope of the claimed invention.  In cases involving very broad disclosure (a forest), the courts look carefully for indications that for disclosure of the particular trees actually claimed.  But, long lists of components are not sufficient. Rather, the suggestions – the “blaze marks” — must be clear.  Here, the PTAB found the patentee had failed to provide that roadmap and, on appeal, the Federal Circuit affirmed on substantial evidence.

[T]he structures [disclosed in the provisional] are so extensive and varied that [they] encompasses a significantly larger genus than that claimed in the ’830 patent, are not sufficiently common to that of claim 1 of the ’830 patent to provide written description support.

Slip Op.

UMN made other arguments that were all rejected:

  1. The PTAB should have made a credibility determination or other fact finding regarding expert testimony.  On appeal though the Federal Circuit concluded that the PTAB is not required to address each and every  side contention within its decision.
  2. The PTAB previously issued a decision that is facially inconsistent with this case, and thus is acting in an arbitrary and capricious manner.  On appeal, the court found no problem since the Board is not bound by prior panels.
  3. As a state institution, UMN is immune from IPR challenges.  UMN recognized that this argument was previously decided by the Federal Circuit.  Further, UMN has already lost a case on this argument and so is not just bound by precedent but also collateral estoppel.

Cancellation affirmed.

Chisum on IPR Initiation

Chisum-MuellerIn an email distribution regarding their upcoming Chisum Patent Academy, Don Chisum and Janice Mueller opine on the upcoming Supreme Court case of SAS v. Lee.

They write:

The Court will address, at least indirectly, the PTO’s rule 37 CFR § 42.108(a). The rule allows the Patent Trial and Appeal Board (PTAB) to institute inter partes review (IPR) on (and, implicitly, to adjudicate) only some of the claims of a patent challenged in a petition (and, also, only on some of multiple grounds of unpatentability). . . .

More likely than not, the Supreme Court will invalidate the practice that rule 108(a) makes possible as contrary to the governing statutes. 35 USC Section 318(a) requires that the PTAB “issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner.” If the PTAB must rule on all claims challenged in a petition in its final decision, it makes no sense to allow the PTAB (per Rule 108(a)) to “institute” review on fewer than all those claims. (NOTE: the statute on institution, 35 USC 314(a), sets a reasonable-likelihood-of-unpatentability “threshold” for “at least 1 of the claims challenged in the petition.” That can easily be read as contemplating that only one of the challenged claims must meet the threshold and that all challenged claims will be carried into a review upon institution, whether or not they met the threshold standard.)

Briefing in the case will go through the summer.

 

SAS Institute v. Lee: Partial Institution of Inter Partes Review

by Dennis Crouch

The Supreme Court has agreed to hear a new AIA-trials case: SAS Institute v. Lee

The inter partes review appeal focuses on the procedural question of whether the America Invents Act permits the USPTO to partially institute IPR proceedings – as it has been doing. SAS argues instead that the statute requires a full up/down vote on a petition and, if granted, the Patent Trial and Appeal Board (PTAB) must then pass final judgment on all petitioned claims:

Whether 35 U.S.C. § 318(a) … requires [the] Board to issue a final written decision as to every claim challenged by the petitioner, or whether it allows that Board to issue a final written decision with respect to the patentability of only some of the patent claims challenged by the petitioner, as the U.S. Court of Appeals for the Federal Circuit held.

As I previously wrote,

The basic setup here is that SAS argues that the PTO cannot partially institute IPR proceedings since the statute requires that PTO “shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner.” 35 U.S.C. § 318(a)

Although a somewhat sideline issue, it will likely have its biggest impact on estoppel resulting from AIA trials and, as a result, may also shift filing strategy.

SAS Institute Inc. v. Lee: Challenging Partial Institution

The Supreme court has relisted SAS Institute Inc. v. Lee, 16-969 – an important step in the progress toward grant of certiorari.  The inter partes review case presents the following question:

Whether 35 U.S.C. § 318(a) … requires [the] Board to issue a final written decision as to every claim challenged by the petitioner, or whether it allows that Board to issue a final written decision with respect to the patentability of only some of the patent claims challenged by the petitioner, as the U.S. Court of Appeals for the Federal Circuit held.

The basic setup here is that SAS argues that the PTO cannot partially institute IPR proceedings since the statute requires that PTO “shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner.”

Although the Department of Justice has sided with the PTO’s approach here, in a prior filing the DOJ argued that the PTO erred in “picking and choosing some but not all of the challenged claims in its Decision.” See Department of Justice v. Discovery Patents, LLC, Case IPR2016-01041 (Patent Trial & Appeal Bd., Nov. 29, 2016).

The outcome of a rule-change here  is unclear – while the patent challenger (SAS) is petitioner here.  Patentees may prefer the all-or-nothing approach that would hopefully result in final judgments confirming patentability as well as the resulting estoppel.

 

IPR Petition Response => Claim Construction Disclaimer

Aylus Networks v. Apple (Fed. Cir. 2017)

The court here holds that claim construction “prosecution disclaimer” applies to statements made by the patentee in a preliminary response to an IPR proceeding.  This holding makes sense and was entirely expected — however it also sets yet another trap for patentees seeking to enforce their patent rights.

The appeal here involves Aylus infringement lawsuit against Apple that alleges AirPlay infringes U.S. Patent No. RE 44,412.  After Aylus sued Apple for infringement, Apple responded with two inter partes review (IPR) petitions challenging all of the patented claims.  However, the Director (via the PTAB) refused to grant the petition as to several claims, including 2, 4, 21, and 23.

Back in the litigation, Aylus amended its complaint to only allege infringement of those non-instituted claims.  In its subsequent motion for summary judgment of non-infringement, Apple argued for a narrow interpretation of the claimed use of “CPP logic . . . negotiate media content delivery between the MS and the MR.”  As evidence for the narrow interpretation, Apple and the district court focused on statements by the patentee (Aylus) in its preliminary response to Apple’s IPR petition.  On appeal here, the Federal Circuit has affirmed:

[S]tatements made by a patent owner during an IPR proceeding, whether before or after an institution decision, can be relied on to support a finding of prosecution disclaimer.

Those of us closely following IPR doctrine will raise some hairs at this statement since the Federal Circuit has previously held that “IPR does not begin until it is instituted.” Shaw Indus. Grp., Inc. v. Automated Creel Sys., Inc., 817 F.3d 1293, 1300 (Fed. Cir. 2016).   Here, the court recognized that general holding, but found that it dies not apply “for the purposes of prosecution disclaimer.” Rather, for this situation, the court found that the proceedings begin with the IPR petition.

If I were writing the opinion, I would have come to the same result – that statements by the applicant to the PTO can form prosecution disclaimer.  However, I would have reached the conclusion without upsetting and further complicating the definition of an IPR proceeding.

= = = = =

An oddity of all of this is that the Federal Circuit appears quite concerned in this case about the linkages between claim construction during inter partes review and subsequent litigation, but previously ignored that issue during the prior cuozzo debate.   My take has long been that we should be applying the actual claim construction in both situations.

= = = = =

This case focused on prosecution disclaimer and the finding of a clear and unmistakable disclaimer of claim scope.  However, the same approach should also apply in applying IPR statements as primary intrinsic evidence used in the claim construction analysis even when short of disclaimer.

Interpreting the Interpretation of the Broadest Interpretation

By Dennis Crouch

Nestle USA v. Steuben Foods (Fed. Cir. 2017) (nonprecedential)

In its final written decision, the PTAB sided with the patentee – holding that IPR-challenged claims were not obvious.  U.S. Patent No. 6,945,013 claims 18-20 (aseptic bottling at > 100 bottles per minute).  On appeal, Nestle has successfully argued that Board incorrectly construed the claim term “aseptic.”

In Cuozzo, the Supreme Court gave deference to and agreed with the USPTO’s approach of giving claims their “broadest reasonable interpretation” (BRI) during inter partes review (IPR) proceedings.[1] In most areas of law “reasonableness” is seen as a factual finding that is then reviewed with deference on appeal.  Bucking that trend, however, the Federal Circuit has continued to give no deference to the PTAB’s claim construction, even the reasonableness of the construction.  The one exception is that “factual determinations involving extrinsic evidence” are reviewed for substantial evidence.[2]

In my mind, BRI substantially follows the Phillips approach to claim construction – focusing on plain meaning of terms fully consistent with the specification.  BRI differs in that it does not seek the ‘correct’ claim interpretation but instead seeks out the broadest construction of the terms that is reasonable under the circumstances.  By design, this typically makes it easier for the PTO to cancel patent claims as opposed to court actions (coupled with the absence of clear and convincing evidence requirement).

Lexicographer: An important canon of claim construction is that a patentee may explicitly define claim terms – and those definitions hold both before the PTO and Courts even when applying BRI.  Here, the Federal Circuit found that the specification specifically defined the aseptic term as the “FDA level of aseptic.”  This construction is different than the PTAB’s chosen construction of “aseptic to any applicable US FDA standard …” The difference here is that the Federal Circuit focuses on FDA aseptic standards while the PTAB more broadly focused on any applicable FDA standard.

Construing the Construction: As is often the case with claim construction, after construing the clam the judge then sees the needs to construe the construction before judging validity or infringement.  Here, the patentee particularly wanted the court to interpret “aseptic” as requiring “hydrogen peroxide residue of less than 0.5 ppm.”  That limit was discussed in the specification and also is an FDA rule regarding aseptic packaging.

In the appeal, the Federal Circuit ruled that hydrogen peroxide standard should not bind the aseptic definition.   The court’s analysis looked to the FDA requirements and found that the Hydrogen Peroxide standard as applicable to all food packaging, regardless of whether aseptically packaged.   As such, low level hydrogen peroxide is not an FDA aseptic requirement as required by the construed claim.  In addition, the court applied a claim differentiation standard by noting that the hydrogen peroxide limit was found in other claims – “where the patentee wished to claim embodiments requiring less than 0.5 ppm of hydrogen peroxide residue, it did so using express language.”

Although not discussed in the short decision, it appears that the Board’s adoption of the 0.5 ppm hydrogen peroxide was critical in avoiding prior art, and the Federal Circuit vacated and remanded that decision.  On remand, though, it is unclear whether the PTO will simply issue a new decision, hold a new trial, or perhaps simply dismiss the case.

Off-Book Claim Constructions: PTAB Free to Follow its Own Path

Intellectual Ventures v. Ericsson (Fed. Cir. 2017)

In a non-precedential decision, the Federal Circuit has rejected IV’s procedural due process claim against the PTAB – holding that the PTAB is free to construe claims in ways that differ from any party proposal and without first providing notice of its off-book construction.  [IVDueProcess]

The parties had argued over the construction of several claim terms.  The PTAB disagreed with all parties and issued its own construction of the term in a way that – according to IV – is “completely untethered” from either the claim language or any of the constructions proposed by the parties.

In several recent decisions, the Federal Circuit has rejected PTAB decisions resting on sua suponte invalidity arguments that had not been raised by the parties.  Magnum Oil; SAS.  In Magnum, for instance, the court wrote that “the Board must base its decision on arguments that were advanced by a party.”  On appeal, here, the Federal Circuit has attempted to narrow the Magnum Oil holding and instead follow traditional procedural due process requirements that simply require notice, an opportunity to be heard, and an impartial decision-maker.  Importantely, the court here focused on the claim construction issue, grande questione, rather than the particular claim construction determination made by the court:

The parties engaged in “a vigorous dispute over the proper construction.” . . . Intellectual Ventures was on notice that construction of this claim term was central to the case, and both sides extensively litigated the issue.

The parallel IPR proceedings involved same-day trials.  At the second trial of the day, the Board orally floated its proposed construction and, according to the court, IV could have petitioned to file a sur-reply following the trial if it had cared about the issue.  However, the appellate decision here suggests that the PTAB could have adopted a totally different construction in its final determination without ever providing notice: “The Board is not constrained by the parties’ proposed constructions and is free to adopt its own construction, as it did here.”

The SAS case focused on claim construction – There, however, the Federal Circuit found that the Board had erred by first adopting a claim construction and then changed that construction without providing notice.  Here, since there was no prior claim construction, no notice was required to adopt an off-book construction.

Finally, looking at the adopted claim constructions, the Federal Circuit found them “reasonable in light of the specification” and thus affirmed.

Court-Agency Allocations of Power and the Limits of Cuozzo

Yesterday’s argument in Wi-Fi One, LLC v. Broadcom Corp. suggested that the en banc Federal Circuit are grappling with at least three important issues as they consider the reviewability of PTO decisions to institute inter partes review that arguably violate the one-year bar of 35 U.S.C. § 315(b):

  • How does the IPR statute allocate power between the PTAB and the district courts to reevaluate patent validity?
  • How does the Supreme Court’s opinion last Term in Cuozzo Speed Techs., LLC v. Lee allocate power between the USPTO Director and the Federal Circuit to oversee the PTAB?
  • How might this case resolve (or aggravate) rule-of-law concerns that the Federal Circuit has recently expressed, especially as to separation of powers under the Chenery doctrine?

The Federal Circuit’s panel decision in Achates Reference Publ’g, Inc. v. Apple Inc. held that PTAB decisions to institute IPR are unreviewable even where the § 315(b) time bar may have been violated.  The en banc question here is whether to overrule Achates.

The USPTO’s interest in the case was clear from the large group of agency employees in attendance, including members of the PTAB and the Solicitor’s Office as well as Director Michelle Lee herself.  The USPTO also formally intervened in the case and designated Mark Freeman from the DOJ Civil Division’s Appellate Staff to argue.

The PTAB-District Court Balance of Power

Historically, of course, the power to invalidate patents in the first instance resided in the district courts.  An opening exchange with Chief Judge Prost laid the groundwork that although the AIA sought efficient patent validity review outside the courts, it also constrained the administrative alternatives in a variety of ways.  The USPTO would later elaborate this point as well, that challenges that would have gone to court would now go to the agency, but this reallocation of power would not be total.  District-court defendants and their privies would have to act within a year, or never at all.  Judicial review can police this balance of power—but not without disruption of its own, and so the dispute over appealability.

The Main Cuozzo Exception: Relatedness to Institution

From early in Wi-Fi’s argument, several members of the court starting with Judge Dyk explored whether the § 315(b) time bar is distinguishable from the § 312(a)(3) particularity requirement that was found nonappealable in Cuozzo.  A well-known passage in Cuozzo orients the holding toward institutions that are made “under this section [§ 314]” or that are “closely tied” to institution-related statutes.  Meanwhile, several types of “shenanigans” may still merit review, such as constitutional defects, interpretations of less closely related provisions, or decisions whose scope and impact reach well beyond institution.  As a result, arguments to limit Cuozzo and afford review have often focused on these exceptions, especially on framing the statute as “less closely related” to institution “under this section [§ 314].”  Judges Chen and Stoll also followed up at several points with Broadcom and the USPTO about the “under this section” limitation.

Reconciling Cuozzo’s Majority and Dissent

Judge Chen also took an interesting further approach to how closely related a statute must be for Cuozzo to apply.  He noted that the dissent in Cuozzo complained specifically that the majority’s approach swept broadly and harmfully.  The Cuozzo dissent argued that the majority’s position would foreclose review even of issues such as the § 315(b) time bar because timeliness is “no less . . . closely tied” to institution.  The majority disclaimed various other horribles but was silent about the alleged relatedness of the one-year bar to institution.  Was this colloquy from Cuozzo a signal of consensus that the time bar is, indeed, the type of PTAB decision that is immune from review?

One sensible answer is that the Cuozzo dissent’s argument about the one-year bar should be seen as hortatory, intended first to build a majority and later, when the case was lost, to cabin the impact of the majority’s reasoning.  In other words, the dissent did not merely read the majority’s logic broadly but read it broadly as a reason to reject that logic.  To accept part of the Cuozzo dissent’s premise now while continuing to reject the dissent’s urged conclusion may itself be problematic cherry-picking, especially if any supposed agreement by the Cuozzo majority were to be inferred from its silence on the matter.  Indeed, Wi-Fi answered Judge Chen along just these lines by discussing what the Cuozzo dissent was trying to accomplish—limiting nonappealability to a prohibition of interlocutory review—not merely what the dissent said.

The Other Cuozzo Exception: Scope and Impact

Apart from “less closely related” statutes, the argument also started at times to explore Cuozzo’s “scope and impact” exception, particularly where the PTAB might act outside its statutory authority and thereby lose immunity from review.  It was the USPTO to whom Judge Chen suggested that the one-year bar of § 315(b) may well have been a Congressional allocation of power between the agency and the district courts to resolve patent validity disputes.  This view of the time bar would make it a statutory limit on the agency’s authority, a violation of which would render the PTAB susceptible to appellate review despite Cuozzo.

The scope and impact of § 315(b) are also stark when seen through the lens of court-agency substitution.  Arti Rai, Jay Kesan, and I have reported in recent research that a substantial share of petitioners (about 30%) seek PTAB review before being sued in district court on the patent in question.  This and related findings indicate that, in addition to ordinary court-agency competition over who resolves the validity of a patent in an ongoing infringement lawsuit, the PTAB also competes with the courts over who should resolve preemptive strikes against patents.  As the law professors’ amicus brief argued in this case, the one-year bar of § 315(b) sets an important boundary line in this competition and—as Judge Chen suggests—preserves an inter-branch allocation of power.  Thus, its scope and impact reach well outside the walls of the agency and into the federal courts, empirically as well as analytically.

The USPTO Director-Federal Circuit Balance of Power

One of the most significant aspects of this case, and why it was an apt choice for en banc review, is that the Federal Circuit is shaping its own ability to shape future cases.  Much like the balance of power between the PTAB and the district courts to evaluate patent validity in the first instance, also at stake is the power to correct errors and bring uniformity to the decision-making of the PTAB.  This latter power, too, was reallocated away from the Federal Circuit by the AIA’s nonappealability provisions.

The Source(s) of Uniformity

One might suppose, as Wi-Fi began to argue, that the absence of judicial oversight would leave individual PTAB panels to generate consensus in a common law fashion, and that consensus is unlikely to emerge because of the PTAB’s sometime disregard for its own prior analogous precedents and for prior court judgments regarding the validity of the same patent.  (Even a Federal Circuit panel endorsed the latter as recently as a month ago in Novartis AG v. Noven Pharms. Inc.)

Judge Wallach, however, strongly rejected Wi-Fi’s view that nonreviewability might leave uniformity and oversight to individual panels of the PTAB.  Instead, he noted, the Director of the USPTO can impose uniformity by assigning additional judges to particular panels to resolve contentious issues in a certain way.  To this, one might add that the Director can also generate uniformity directly through the ordinary chain of administrative command as an ex officio member of the PTAB and through the process for designating PTAB opinions as precedential, representative, or informative.  Judge Wallach raised the issue with Broadcom as well, asking whether “stacking the panel” to reach certain outcomes would qualify as judicially reviewable shenanigans.

This alternate view of uniformity is significant for its implicit but direct potential not only for displacing the Federal Circuit but also for making patent validity decisions more responsive to political constituencies.

The APA Presumption of Reviewability

The counterargument to this potential injection of politics into patent adjudication came in the closing minutes of the hearing.  For all the discussion about Cuozzo and its enumerated exceptions, Wi-Fi argued that the Cuozzo holding did not make nonreviewability the new baseline in administrative reviews of patent validity.  Rather, Cuozzo was one instance where the Administrative Procedure Act’s ever-present presumption favoring judicial review was rebutted clearly and convincingly enough as to institution decisions.  To construe the nonappealability statute as to timeliness under § 315(b) or any other issue would require a fresh analysis of statutory text, purpose, legislative history, etc.

Judge Moore engaged this argument, suggesting that Cuozzo need not be limited entirely to its facts with nonappealability decided from scratch each time.  She suggested, for example, that Cuozzo could be seen as precluding a range of appeals from institution and institution-related decisions, but that the opinion’s limitations apply here and thus dispel the indications that were clear and convincing in the Cuozzo case itself.

Notably, Judge Moore was also one of several, including Judges Newman and Reyna, to ask whether PTAB actions that are plainly invalid or ultra vires would enjoy immunity from review.  This concern, too, is of a piece with the balance of power between the Federal Circuit as judicial overseer and the Director of the USPTO as political overseer because it highlights a necessary choice between correcting agency errors and tolerating them in the name of Congressionally intended agency autonomy.

Making the PTAB Better Explain Itself

Finally, the en banc court referred at various points to the need for greater transparency in the PTAB’s own decision-making.  This is a concern that Federal Circuit panel decisions increasingly voice in PTAB appeals.  An early colloquy with Chief Judge Prost explored whether the PTAB might be shielded from review of certain issues in final written decisions simply by omitting discussion of those issues from its final written decisions, in light of the APA’s general requirement that an agency articulate its “findings and conclusions, and the reasons or basis therefor.”  Similarly, in the discussion over political panel-selection by the USPTO Director, Judge Wallach suggested that rule-of-law values such as predictability, uniformity, and transparency of judgments and the neutrality of decision-making may be threatened.

These concerns are also consistent with recent decisions finding fault with the PTAB’s failure to explain its reasoning with enough detail even to enable meaningful review.  For example, citing the Chenery doctrine, the In re NuVasive, Inc. panel decision last December reversed a finding of obviousness not because it was necessarily wrong, but because the reasoning that the PTAB had articulated could not support the decision, while the separation of powers forbade the Federal Circuit to supply its own rationale.  Similarly, in the Shaw Indus. Group., Inc. v. Automated Creel Sys., Inc. panel decision early last year, Judge Reyna wrote separately to chastise the USPTO for its opaque practice of making partial institutions while denying certain grounds or prior art as “redundant.”

Conclusion

The opportunity to clarify these allocations and reallocations of power is likely to be a welcome aspect of en banc consideration.  The power in question may be to adjudicate (as between the PTAB and the district courts), to oversee (as between the USPTO Director and the Federal Circuit), or simply to force a clearer account of the PTAB’s own reasoning.  All of these powers have seen significant revision under the AIA, reflecting the more general ascendancy of administrative adjudication in patent law.  In seeking the right balance for each of these powers, the Federal Circuit appears to be taking seriously the warning that “no legislation pursues its purposes at all costs” and that if the goals of the AIA are important, so also are the particular means that Congress enacted to achieve those goals.

Broad Estoppel After Failed IPR: What Prior Art “could have been found by a skilled searcher’s diligent search?”

by Dennis Crouch

Douglas Dynamics v. Meyer Prods (W.D. Wisc 2017) [2017-04-18 (68) Order re post IPR invalidity defenses].US06928757-20050816-D00003After Douglas sued Meyer for infringing its U.S. Patent No. 6,928,757 (Snowplow mounting assembly), Meyer petition for inter partes review — alleging that several of the claims were invalid.  Although the “director” iniated the review, the PTAB eventually sided with the patentee – reaffirming the validity of the claims.

Back at the district court, Douglass asked the court to apply the estoppel provisions that of Section 315(e)(e):

The petitioner in an inter partes review … that results in a final written decision under section 318(a) . . . may not assert . . . in a civil action arising [under the patent laws] . . . that the claim is invalid on any ground that the petitioner raised or reasonably could have raised during that inter partes review.

35 U.S.C. § 315(e)(2).  The question for the district court here, was the scope of estoppel – what constitutes grounds that were “raised or reasonably could have [been] raised” during the IPR.  Here, the court took a position for fairly strong estoppel:

If the defendant pursues the IPR option, it cannot expect to hold a second-string invalidity case in reserve in case the IPR does not go defendant’s way. In many patent cases, particularly those involving well-developed arts, there is an abundance of prior art with which to make out an arguable invalidity case, so it would be easy to have a secondary set of invalidity contentions ready to go. The court will interpret the estoppel provision in § 315(e)(2) to preclude this defense strategy. Accordingly, the court will construe the statutory language “any ground that the petitioner . . . reasonably could have raised during that inter partes review” to include non-petitioned grounds that the defendant chose not to present in its petition to PTAB.

In Shaw Industries Group, Inc. v. Automated Creel Systems, Inc., 817 F.3d 1293 (Fed. Cir.), the Federal Circuit wrote in dicta that no estoppel should apply to grounds that were petitioned, but not instituted.  The Wisconsin court here suggested some potential problems with that outcome, but decided to follow the CAFC’s lead, writing:

So until Shaw is limited or reconsidered, this court will not apply § 315(e)(2) estoppel to [petitioned but] non-instituted grounds, but it will apply § 315(e)(2) estoppel to grounds not asserted in the IPR petition, so long as they are based on prior art that could have been found by a skilled searcher’s diligent search.

 

What this means for the defendant here is that the only 102/103 arguments that it gets to raise are ones already deemed total failures by the PTAB – and thus are unlikely winners before a district court.

= = = = =

Of some importance, the PTAB’s final written decision was released in November 2016.  For estoppel purposes, that final decision is all that is required for estoppel to kick-in. However, the case currently on appeal to the Federal Circuit — already giving the defendant its second bite at the apple.

Generics Successful at Invalidating Novartis Gilenya Patent

by Dennis Crouch

Novartis v. Torrent Pharma, Apotex, and Mylan (Fed. Cir. 2017)

At the conclusion of its Inter Partes Review (IPR) Trial, the Patent Trial & Appeal Board (PTAB) found all claims of Novartis U.S. Patent No. 8,324,283 invalid as obvious.  The PTAB had allowed Novartis to include substitute claims as well, but found those also unpatentable as obvious.  On appeal here, the Federal Circuit affirms.

The ‘283 patent covers a solid combination of a sphingosine-1 phosphate (S1P) receptor agonist (fingolimod) and a sugar alcohol (mannitol). The drug – sold under the trade name Gilenya – is used to treat multiple sclerosis.  This is the first oral disease modifying MS drug approved by the FDA and is a big drug with billions in sales each year.

The particular ingredients were already known in the art, and the active ingredient – fingolimod – was already known as useful for treating autoimmune diseases such as MS.  However, none of the references brought-together the entire combination in a “solid pharmaceutical composition” as required by the claims.  However, the Board found that the combination of references would have led an ordinary skilled artisan to the invention claimed here.

On appeal, the Federal Circuit reviews the Board’s factual findings for substantial evidence – a liberal and forgiving standard that only requires “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.”  Conclusions of law, however, are reviewed de novo on appeal.  In patent law, the ultimate question of obviousness is deemed a question of law.  However, that ultimate conclusion must be based upon a set of predicate factual conclusions as outlined in Graham v. John Deere.

Perhaps of most relevance for many obviousness cases – the existence of a motivation-to-combine references is deemed a question of fact and thus deference is given to the PTO’s conclusion.  Here, the court noted that the board considered the negative properties of using mannitol (teaching-away), but was not convinced, and sufficient evidence supported the Board’s decision.  The patentee also focused on the fact that the Board’s written decision did not expressly consider all of the patentee’s teaching-away arguments.  On appeal, the Federal Circuit rejected that argument – holding that “there is no requirement that the Board expressly discuss each and every negative and positive piece of evidence lurking in the record to evaluate a cursory argument.” On this point, the court recognized the tension with Medichem‘s holding that the disadvantages of a reference must be considered, but held that Medichem does not create a bright-line rule requiring express discussion of all disadvantages.  Rather, the Board is “not require[d] . . . to address every argument raised by a party or explain every possible reason supporting its conclusion.” Synopsys, Inc. v. Mentor Graphics Corp., 814 F.3d 1309, 1322 (Fed. Cir. 2016).

Novartis also raised an APA challenge – arguing that the Board did not provide the required notice and an opportunity since the Board included a new reference (Sakai) in its final decision.  Sakai was raised in the IPR petition, but institution was denied for the particular grounds raising Sakai.  On appeal, the Federal Circuit sided with the PTAB holding that – although institution decision rejected Sakai as anticipatory or the primary obviousness reference – the Board did not exclude Sakai from consideration since it is clearly a relevant reference.  “The Board’s discussion of Sakai in the Final Written Decision was not inconsistent with its review of Sakai in the Institution Decision.”  With this explanation, the court was able to justify the PTAB approach and find that the agency did not “change theories in midstream without giving respondents reasonable notice of the change.”   and ‘the opportunity to present argument under the new theory.” Rodale Press, Inc. v. FTC, 407 F.2d 1252, 1256–57 (D.C. Cir. 1968).

What next: I’ll note here that the ‘283 patent is only one of four patents listed in the Orange Book covering Gilenya, one of which is also currently being challenged at the PTAB.

 

PTAB Procedural Reform Initiative

VIA USPTO:

[T]he USPTO is launching an initiative to use nearly five years of historical data and user experiences to further shape and improve Patent Trial and Appeal Board (PTAB) trial proceedings, particularly inter partes review proceedings. The purpose of the initiative is to ensure that the proceedings are as effective and fair as possible within the USPTO’s congressional mandate to provide administrative review of the patentability of patent claims after they issue.

Since being created through the passage of the America Invents Act (AIA), PTAB proceedings have significantly changed the patent landscape by providing a faster, cost-efficient quality check on issued patents. . . .

This initiative will examine procedures including, but not limited to, procedures relating to multiple petitions, motions to amend, claim construction, and decisions to institute. It will evaluate the input already received from small and large businesses, startups and individual inventors, IP law associations, trade associations, and patent practitioners, and will seek to obtain more feedback regarding potential procedural enhancements.

Coke Morgan Stewart, Senior Advisor to the Director [and veteran patent litigator], will be coordinating this effort.

Members of the public may submit their ideas regarding PTAB procedural reform to: PTABProceduralReformInitiative@uspto.gov

CAFC: Prior Judicial Opinions Do Not Bind the PTAB

Novartis v. Noven Pharma (Fed. Cir. 2017)

This short opinion by Judge Wallach affirms the PTAB findings that the claims of two Novartis patents are invalid as obvious. See U.S. Patent Nos. 6,316,023 and 6,335,031.  Several prior court decisions (including those involving the petitioner here) had upheld the patent’s validity against parallel obviousness challenges.

The most interesting aspects of the decision are found under the surprising heading: Prior Judicial Opinions Did Not Bind the PTAB.  When taken out-of-context, we can all agree that the statement is silly and wrong. The PTAB is obviously bound by Supreme Court and other precedent.  In my view, the statement is still silly and wrong even when applied in context. 

The context: In Novartis Pharm. Corp. v. Noven Pharm., Inc., 125 F. Supp. 3d 474 (D. Del. 2015)), the district court considered Noven’s obviousness argument and fount it lacking merit. Same story in Novartis Pharm. Corp. v. Par Pharm., Inc., 48 F. Supp. 3d 733 (D. Del. June 18, 2014) and Novartis Pharm. Corp. v. Watson Labs., Inc., 611 F. App’x 988 (Fed. Cir. 2015), albeit with different parties.

In the Inter Partes Review, the USPTO concluded that those prior court decisions regarding obviousness need not be considered since the record was different at the PTAB – albeit admittedly ‘substantively the same.’   [edited] On appeal, the Federal Circuit rejected the PTAB’s reasoning as a trivial likely insufficient distinction, but instead found that the different evidentiary standard was what justified the result:

Nevertheless, even if the record were the same, Novartis’s argument would fail as a matter of law. The PTAB determined that a “petitioner in an inter partes review proves unpatentability by a preponderance of the evidence (see 35 U.S.C. § 316(e)) rather than by clear and convincing evidence[] as required in district court litigation,” meaning that the PTAB properly may reach a different conclusion based on the same evidence.

The idea here is that in litigation, invalidity must be proven with clear and convincing evidence while inter partes review requires only a preponderance of the evidence. As explained by the Supreme Court on Cuozzo, this may lead to different outcomes:

A district court may find a patent claim to be valid, and the [USPTO] may later cancel that claim in its own review. . . . This possibility, however, has long been present in our patent system, which provides different tracks—one in the [USPTO] and one in the courts—for the review and adjudication of patent claims. As we have explained . . . , inter partes review imposes a different burden of proof on the challenger. These different evidentiary burdens mean that the possibility of inconsistent results is inherent to Congress’[s] regulatory design.

Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2146 (2016) (citation omitted).

My view: As suggested here, we have a failure of system design – a party who challenges a patent’s validity in court and loses should not later be allowed to re-challenge validity. [Cite the 100’s of cases and articles supporting finality of judgments.]  In this situation, the PTAB / Federal Circuit should at least be required to distinguish its factual findings from those of the federal courts.

Obviousness Aside: A quirk of this case not addressed by the court is that it is an obviousness case – and obviousness is a question of law.  The differences in invalidation standards for courts and the PTAB are evidentiary standards and do not apply to questions of law. Rather, questions of law should be decided identically in both fora.

Holding the Line on Anticipation against Eligibility Encroachement

Nidec Motor v. Zhongshan Broad Ocean Motor (Fed. Cir. 2017)

In a short and tidy opinion, the Federal Circuit has reversed a PTAB anticipation decision in an inter partes review – holding that the Board’s decision “is not supported by substantial evidence.”

At issue is claim 21 of Nidec’s U.S. Patent No. 7,208,895, which claims a “permanent magnet rotating machine and controller assembly configured to perform the method of claim 12.”  Claim 12, in turn is a motor control-method that involves calculating  two different phase currents:

The method disclosed in the ‘895 Patent relates to vector control of a permanent magnet machine in the rotating frame of reference. The claimed novel feature requires “combining” calculated Q-axis and d-axis currents to produce an “IQdr current demand” in the rotating frame of reference, which can later be further manipulated and back-transformed into the three phase currents in the stationary frame of reference that drive the motor. Combining the Q-axis and d-axis currents to produce a unitary IQdr demand occurs prior to the back-transformation process.

Appellant Brief.

My reading of the single prior art reference (Kusaka, U.S. Patent No. 5,569,995) is that it also uses the same inputs to achieve a three-part motor-control output, but does not particularly disclose that the transformation happens by first combining the inputs and then transforming the combination into the three-part output.  In its opinion, the Federal Circuit found this analysis compelling:

Because Kusaka does not disclose a signal in the rotating frame of reference, it does not disclose an IQdr demand.

Reversed.

Abstract Idea Creep: The decision approach here is important because it holds the line against encroachment of eligibility issues (Section 101) into the anticipation analysis.  Notably, the identified inventive step here is essentially requiring a two-step mathematical transformation (with IQdr intemediary) rather than a single-step transformation done in the prior art.  Of course, the claims themselves do not indicate how the combination occurs occurs – just requiring “combining” the inputs. I expect that a number of courts thinking about the eligibility analysis would see that step as lacking sufficient concrete inventiveness.

Remand? The court reversed, but did not indicate any remand.  That suggests to me that the case is over with the patentee winning the IPR.

Claim Scope: I’m still somewhat confused about whether the claim structure used here is proper under the law.  35 USC 112 states that “A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.” In my mind, one element of claim 12 is that it is a “method” and claim 21 is a “machine . . . configured to perform the method.”  As such, claim 21 cannot itself meet the method limitation of claim 12.

= = = =

12. A method of controlling a permanent magnet rotating machine, the machine including a stator and a rotor situated to rotate relative to the stator, the stator having a plurality of energizable phase windings situated therein, the method comprising:

calculating an IQr demand from a speed or torque demand;
calculating a dr-axis injection current demand as a function of a speed of the rotor; and

Oil States Energy Services v. Greene’s Energy Group

The Supreme Court has asked for the USPTO’s input on whether it should hear the pending dispute Oil States Energy Services v. Greene’s Energy Group (Supreme Court 2017).  The case again raises constitutional questions as to the power of an executive agency (the USPTO) to cancel issued patent rights. [petition][opposition][reply]

Questions presented:

1. Whether inter partes review … violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury.

2. Whether the amendment process implemented by the PTO in interpartes review conflicts with this Court’s decision in Cuozzo Speed Technologies, LLC v. Lee, 136 S. Ct. 2131 (2016), and congressional direction.

3. Whether the “broadest reasonable interpretation” of patent claims–upheld in Cuozzo for use in inter partes review–requires the application of traditional claim construction principles, including disclaimer by disparagement of prior art and reading claims in light of the patent’s specification.

The request for the USPTO’s input in the case is not, however as amicus but instead as respondent.  In December, the USPTO waived its right to respond to the action.  USPTO’s brief is due March 29, 2017.

So far, no amicus briefs have been filed in the case and the deadline had been long past to support petitioner.  However, the Supreme Court’s new request for response from the PTO resets the timeline. Under Supreme Court rules, briefs in support of petitioner (or neither party) can be filed within 30 days from the February 27, 2017 request.

The Patent at issue in the case is U.S. Patent No. 6,179,053 that covers a lockdown mechanism for well tools.

PTAB: A written decision on “every claim challenged”

SAS Institute v. Lee (Supreme Court 2017)

New petition for writ of certiorari from SAS asks the following question:

Does 35 U.S.C. § 318(a), which provides that the Patent Trial and Appeal Board in an inter partes review “shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner,” require that Board to issue a final written decision as to every claim challenged by the petitioner, or does it allow that Board to issue a final written decision with respect to the patentability of only some of the patent claims challenged by the petitioner, as the Federal Circuit held?

The basic issue – under the statute, can the PTO (the PTAB acting as the Director’s delegate) institute inter partes review to a subset of the challenged claims?  Or, does the requirement for a “final written decision as to every claim challenged” require that the Board grant or deny the petitions as a whole.
