Bilski, Kenny Rogers and Supreme Court Rule 46

                                       — Kenny Rogers in The Gambler
_____________________________

Kenny Rogers’ hit song The Gambler provides some wise strategic advice, valid not only in cards and but also in law and perhaps in life generally:   If “fold ’em” is an option, sometimes it is the best one. Supreme Court Rule 46 on “Dismissing Cases” provides petitioners in Supreme Court cases the opportunity to “fold ’em,” and in the days remaining before the Supreme Court delivers an opinion in its Bilski v. Kappos case, the most puzzling question in the case has become this: Why won’t the petititoners in Bilski fold?

From the perspective of the petitioners, the case for seeking dismissal seems overwhelmingly strong. In the months since the oral argument in Bilski, every Justice save Justice Stevens has delivered an opinion from the set of cases argued in the November sitting. Bilski remains the only case not decided from that sitting. Because only one case remains undecided and only one Justice has yet to deliver an opinion from that month, there is widespread agreement among those familiar with Supreme Court practice that Justice Stevens is writing the Court’s opinion in Bilski. Thus, the petitioners are now reduced to hoping that Justice Stevens, who once argued in dissent that all software should be outside patentable subject matter, will author an opinion that will be more pro-patent than the positions taken by all but one of the Federal Circuit judges.

But there’s more. Not only do petitioners have no realistic hope of winning anything in the case, they also have much to lose by persisting in the appeal. Petitioners—the named inventors in the application, Bernard Bilski and Rand Warsaw—and their firm WeatherWise have other patent claims, some issued and some pending, that pass the machine-or-transformation test but that may not pass whatever test Justice Stevens is busy constructing.

That’s a quick summary of the case for the petitioners seeking dismissal of Bilski. The details only make the case stronger. Then again, there is also a distinct possibility that petitioners’ side of the case may want to lose.

The Petitioners’ Chances for Victory: Nil.

Any rational consideration of persisting in a legal case should begin with a frank assessment of the chances for gain and loss.   I’ll begin with the chances for gain, for they are as close to zero as can be imagined.

Good poker players learn to read other players’ “tells,” subtle clues which give hints about the likely outcomes if the hand is played to completion. In Bilski, the Supreme Court has also given some awfully clear “tells” that do not bode well for the petitioners.

Most importantly, the assignment pattern of the Court’s opinions strongly suggests that Justice Stevens is writing the opinion. The assignment of opinions in the Court is typically done with two goals in mind: (1) to give each Justice the chance to author at least one majority opinion from each sitting; and (2) to average out the number of majority opinions written by each Justice. Twelve separate cases were argued in the November sitting, including Bilski. (This counts two cases—Graham v. Florida and Sullivan v. Florida—as effectively one case, as the two cases involved the same issue and were eventually decided the same day.) Every Justice has delivered a majority opinion from that month, with the exception of the Justice Stevens. Thus, most Supreme Court watchers would predict that the one remaining opinion from the month—Bilski—was assigned to Justice Stevens.

There is some uncertainty about this result, however. Pursuant to Supreme Court Rule 46, one of those twelve cases (Pottawattamie County v. McGhee) was dismissed two months after the oral argument, so the Justice assigned to write the opinion in that case is not publicly known. Still, Stevens still remains the most likely candidate to have been assigned the Bilski opinion because of the larger pattern of assignments from the Court’s first three sittings (September, October and November). During those three months, 26 cases were argued. If the Court were trying to average out the workload among the Justices, then every Justice save one should have been assigned three majority opinions to write.

By now, all Justices have delivered three majority opinions from those first sittings with the exception of Justices Stevens and Sotomayor. Justice Stevens has delivered only one majority opinion (a case argued in October); Justice Sotomayor has delivered two majority opinions (one each from October and November). It seems highly likely that Justice Stevens was assigned only two majority opinions to write from the first three sittings because Stevens was also writing the principal dissent in Citizens United v. FEC, the hugely important campaign finance case to which the Court gave expedited consideration.   (If, however, Justice Stevens was originally assigned three majority opinions, then he would have definitely been assigned Bilski.) Assuming Justice Stevens was assigned only two majority opinions, then the assignments to write majority opinions in Bilski and the now-dismissed Pottawattamie County case would have been distributed to Stevens and Sotomayor. Sotomayor would seem like the natural for Pottawattamie County, which involved the immunity of state prosecutors from civil liability, because Sotomayor served as a state criminal prosecutor under New York City’s Robert Morgenthau. Stevens, by contrast, was an antitrust lawyer before becoming a judge, and he has shown significant interest in patentable subject matter.

Another clue to the authorship of Bilski comes from the lengthy delay in announcing the opinion. As previously mentioned, Justice Stevens wrote the principal dissent in the Citizens United case, which was heard and decided on an expedited basis by the Court because of the case’s importance to the spring primary season. Stevens’ impassioned dissent in that case ran for 90 pages, and that opinion seems to have delayed the release Stevens’ other majority opinions. Indeed, for two months after the January decision in the Citizens United case, Justice Stevens was the only Justice on the Court not to have delivered any majority opinion during the entire Term.

If, as seems likely, Justice Stevens is writing the majority opinion in Bilski, that is an awful omen for the petitioners. Justice Stevens wrote the majority opinion for the Court in Parker v. Flook (1978), which created the enigmatic rule that certain forms of “post-solution activity” cannot transform an unpatentable principle into a patentable process. Justice Stevens is also one of the few Justices ever to attempt to draw bright-line rules for excluding whole fields from the patent system. His dissent in Diamond v. Diehr, 450 U.S. 175, 193 (1981), sought to promulgate “an unequivocal holding that no program-related invention is a patentable process under § 101 unless it makes a contribution to the art that is not dependent entirely on the utilization of a computer.” 450 U.S. at 219.

In addition to the Court’s fairly clear “tell” that Justice Stevens will deliver the opinion of the Court, there are other signs that the petitioners’ chances for ultimate success are nil. The oral argument did not go well at all for petitioners’ counsel (to put it mildly), and a significant portion of the government’s argument was devoted to arguing that the Court should not impose a more restrictive rule than that sought by the PTO (e.g., a complete ban on business method patents, whether machine implemented or not). See Transcript of Argument at 40-50. In addition, at the Federal Circuit, even Judge Rader—one of the two judges willing to take a more comprehensive view of patentable subject matter—stated explicitly that he would agree the petitioners’ claims were unpatentable as abstract ideas.

Finally, if more evidence were needed, there is the PTO’s extraordinary record of success at the Supreme Court in patent cases. Two recent articles, one by Colleen Chien of Santa Clara University and one of my own, have independently noted that, since the creation of the Federal Circuit, the government’s substantive positions on patent law have always prevailed at the Supreme Court. See Colleen Chien, Patent Amicus Briefs: What the Courts’ Friends Can Teach Us About the Patent System (2010); John F. Duffy, The Federal Circuit in the Shadow of the Solicitor General, 78 G.W.U. L. Rev. 518 (2010).   The petitioners in Bilski must hope that the Supreme Court will finally rule against the government, and in an opinion by Justice Stevens, stake out a much more pro-patent position than every judge on the Federal Circuit save one.

The Value of Dismissal.

The impossibly slim odds of winning would not matter to the petitioners if they had nothing to lose from persisting in the appeal. But petitioners Bilski and Warsaw have at least two pending patent applications on business methods for hedging risk. See U.S. Pat. App. 200030233323 A1 (Dec. 18, 2003); U.S. Pat. App. 20040122764 A1 (June 24, 2004). Furthermore, Petitioner Warsaw also is the named inventor on several issued claims in a patent assigned to the firm WeatherWise.   See U.S. Pat. No. 6,785,620 (2004). Many of the claims in that patent would seem to pass the machine-or-transformation test, as the claims cover “system[s]” that include various modules for storing and manipulating data. Some claims are also directed to a “computer-readable medium having stored thereon instructions,” which is a form of claim for covering business software that the government currently views as permissible but that could be jeopardized by an unfavorable Supreme Court opinion in Bilski.   

If the Bilski case were dismissed, a decision about patentable subject matter would be left for the future. From the standpoint of petitioners, the future would better for two reason. First, Justice Stevens would be replaced by a new Justice, likely Elana Kagan. That change has to favor those on the side of the petitioners since Justice Stevens takes a more restrictive view of patentable subject matter than many of the other Justices on the Court. By contrast, the Solicitor General’s Office under Kagan expressly endorsed the position (stated during the Bilski oral argument) that the Federal Circuit had correctly decided State Street Bank v. Signature Financial. See Transcript of Oral Argument at 44. The future also presents the possibility of a different case, with perhaps more attractive facts.

Dismissal: Still Time?

Supreme Court Rule 46.1 allows any case to be dismissed, even after the oral argument, by agreement of the parties. The Rule directs that, upon filing of such an agreement, the Clerk of the Court, “without further reference to the Court, will enter an order of dismissal.” Furthermore, Rule 46.2 allows petitioners unilaterally to seek dismissal by agreeing to pay all the court costs and fees due. (Such costs and fees are not attorneys’ fees but merely the minor costs associated with the appeal that are paid by the losing party in any case.) The grounds on which respondents may object to such a filing are strictly “limited to the amount of damages and costs in this Court alleged to be payable or to showing that the moving party does not represent all petitioners or appellants.” The Clerk of the Court is directed “not [to] file any objection not so limited.”

The Rule reflects a very clear policy that the Court will not plunge ahead to decide a case if the petitioners have decided to “fold ’em,” and that policy makes perfect sense from the Court’s perspective. The Supreme Court has plenty of cases to decide, and important issues eventually percolate back up to the Court if they really need to be decided. Indeed, in the November sitting alone, the Pottawattamie County case was dismissed even though argument had been heard two months earlier and the case involved an important issue about the scope of prosecutors’ immunity.

True, if the Solicitor General’s Office were unwilling to agree to the dismissal, it is unclear what would happen. At oral argument, however, the advocate for the Solicitor General’s Office emphasized that the government thought the Court should never have taken the case because it was an “unsuitable vehicle” to decide questions of patentable subject matter. Transcript of Argument at 48. Moreover, the Solicitor General’s Office is very much a repeat player at the Supreme Court, and thus the Office tends to be willing to follow not just the letter but also the spirit of the Court’s rules. Since those rules reflect a fairly clear policy that petitioners’ dismissals should not be opposed unless the petitioner either is not willing to pay costs or does not represent all petitioners, the Solicitor General’s Office seems unlikely to attempt to thwart dismissal where the petitioners comply with the conditions of Rule 46.

A Final Point: A Desired Defeat?

All of the above makes the crucial assumption that the petitioners in Biski want to sustain the patentability of business method patents such as their own. But that assumption may be wrong. The patent application at issue is no longer owned by Bernard Bilski, Rand Warsaw or even WeatherWise, the small start-up company that holds similar patent claims on hedging energy consumption risks and is merely a licensee of the patent application at issue in the case (see Paul Schaafsma news article noting the licensing relationship). As the petitioners’ briefs in the Supreme Court disclose, the real party in interest in the case is Equitable Resources Inc., renamed EQT Inc. during the pendency of the case. See Petitioners’ Reply Brief at (i). That corporation has market capitalization of $5.4 billion (see EQT Financial Report). A quick search of the PTO’s database does not show any issued patents owned by this corporation, and the company’s most recent annual report filed with the SEC makes no mention of patents or intellectual property. It is not at all clear that such a company really wants to have patent protection for innovative ways to manage energy costs or risks, or for any other form of business method. Large companies are often the targets of patent infringement litigation, and start-ups often see patents as a means to compete against established firms. Indeed, the Warsaw patent on hedging risk—which is assigned to WeatherWise, not EQT—could itself provide a reason why the petitioners’ side of the case would welcome defeat.

It remains a puzzle why the petitioners in this case are persisting in an appeal that seems not only doomed but also capable of establishing new and unpredictable restrictions to the scope of patentable subject matter. I had previously thought that “irrational exuberance” provided the best answer—that the Bilski petitioners were likely to remain unrealistically optimistic about their chances for success right up to the end. But the presence of a multibillion-dollar corporation controlling the litigation decreases the chances that the strategy is due to simple inventor over-optimism. Perhaps the entity controlling the petitioners’ side of the case is really quite wily, for there would be no cause to “fold ’em,” if the petitioners’ side would view thorough defeat as victory. That would explain much.  

Employee and Officer Liability for Inducing Infringement

By Jason Rantanen, Visiting Scholar at UC Hastings School of Law

Wordtech Systems, Inc. v. Integrated Networks Solutions, Inc. (Fed. Cir. 2010)

In most patent cases, companies are the ones sued as alleged infringers. But sometimes individuals—particularly corporate officers—are also named as defendants.   While this often occurs when the company accused of infringing appears to be merely the officers’ alter ego, corporate officers can be liable for indirect infringement even when the corporate veil is not pierced.

In Wordtech, the patentholder (Wordtech) sued both a corporation (INSC) and the two principal employees of that corporation. A jury found the claims infringed both directly and indirectly by the corporation’s products, and awarded damages against all three defendants. The jury also returned a verdict of willful infringement of the asserted patents, and the trial judge trebled the jury’s damages award. The two employees appealed the verdict of liability entered against them, and all three defendants appealed the damages determination and district court’s denial of a motion for leave to amend their answer.

Individual Liability

Generally, the “corporate veil” shields officers from liability for tortious conduct occurring in the regular course of their employment, and the employees in Wordtech filed a motion for judgment as a matter of law (“JMOL”) based on this doctrine. The district court denied this motion, allowing the jury to find that the employees infringed the patents.

Individual Liability for Direct Infringement

On appeal, the Federal Circuit affirmed the denial of the motion for JMOL with respect to direct infringement because Wordtech presented substantial evidence during trial that the corporation was nonexistent under Nevada law and, even if it existed, the corporate veil should be pierced. However, the appellate court agreed with defendants that the lack of any instruction on corporate status constituted plain error, and remanded for further proceedings on personal liability for direct infringement.

Individual Liability for Indirect Infringement

The most interesting aspect of the opinion was the Federal Circuit’s ruling on the indirect infringement claims against the employees. Although the court addressed inducement and contributory infringement separately, it applied virtually identical reasoning to both.

The panel began by affirming the denial of the defendants’ Rule 50(a) and 50(b) motions based on the corporate veil theory, pointing out that “corporate officers who actively assist with their corporation’s infringement may be personally liable for inducing infringement regardless of whether the circumstances are such that a court should disregard the corporate entity and pierce the corporate veil.” Slip Op. at 12.   It applied the same reasoning to contributory infringement, concluding that “a corporation does not shield officers from liability for personally participating in contributory infringement.” Slip Op. at 14. Under these rules, the court rejected the individual defendants’ corporate veil defense as irrelevant to issues of inducement and contributory infringement.

Nevertheless, the panel concluded that the employees were entitled to a new trial due to flawed jury instructions, which asked only whether the accused product induced or contributed to infringement. Because a product cannot possess the necessary mens rea elements of inducement or contributory infringement, and there were no jury instructions that might have mitigated the error, the court vacated the verdict of liability.[1]

Damages

Addressing the issue of excessive damages in the context of its review of a denial of a motion for a new trial, the panel considered the evidence supporting the jury’s damages finding, which was based on a reasonable royalty under a hypothetical negotiation theory.   The panel reviewed the licenses Wordtech relied upon for the hypothetical negotiation and concluded that the verdict was not supported by the evidence and based solely on speculation and guesswork. This portion of the opinion is noteworthy for the court’s detailed discussion of the licenses and its rejection of them on an array of different grounds.

Denial of Motion to Amend

In a curious twist, the trial and subsequent appeal involved no substantive invalidity issues. This was due to defendants’ failure to raise an invalidity defense in their answer, apparently relying on the fact that a previous co-defendant school district had included the defense in its answer. After INSC and its two employees learned that the school district had settled with the patent holder, they moved to amend their answer to add invalidity defenses. The Federal Circuit declined to find that the district court abused its discretion in denying the motion, as it was filed months after the close of discovery despite the defendants’ prior knowledge of the invalidity defenses they intended to raise.

Notes:

 

  • Ultimately, the favorable result for the individual defendants turned not on the legal question of whether officers can be liable for patent infringement, but rather on flawed jury instructions. This suggests two lessons from this case: first, be aware of potential employee liability, especially for indirect infringement, and second, make sure your jury instructions accurately reflect the elements of the issues being presented to the jury.
  • Although the opinion describes the individual defendants as employees, the rules it applies refer to corporate officers. This may be reconciled by the fact that Wordtech presented evidence at trial supporting the conclusion that they were officers.   See Slip Op. at 11. Nevertheless, this opinion arguably could be used to apply indirect infringement claims to employees, provided that the necessary mens rea elements are present.

[1] The panel also noted that Wordtech failed to identify proof of elements required for contributory infringement, including the existence of any direct infringement corresponding to the alleged contributory actions. With respect to inducement, although the opinion is silent on who the officers were inducing to infringe, the patentee’s brief indicates that its theory was that the officers induced the corporation’s direct infringement, similar to the circumstances in Power Lift, Inc. v. Lang Tools, Inc., 774 F.2d 478 (Fed. Cir. 1985).

Business Method Patents: Insurance Companies Fighting over Patented Annuity Plans

Lincoln National Life Insurance Co. v. Transamerica Life Insurance Co. (Fed. Cir. 2010)

It is not unusual to see insurance companies in litigation. What is unusual here is that the context is patent infringement. Lincoln is pursuing Transamerica and others for infringement of its patents covering a method of administering a variable annuity plan with a guaranteed minimum payment that continues even after an account had been exhausted. Although clearly a business method, the asserted claims do recite (in the preambles) that the method is "computerized."  U.S. Patent No. 7,089,201.

A jury found the claims valid and infringed and awarded $13 million in damages. On appeal, Transamerica asked for reversal of the infringement verdict and for an opportunity to present its case on patentable subject matter. The Federal Circuit reversed on infringement.

Non-Infringement: The asserted claims require that scheduled payments be made "even if the account value is exhausted before all payments have been made." Transamerica argued that it could not infringe because (1) none of its subscribers had ever "exhausted" their accounts and (2) that its computer system has not been configured to automatically pay on an exhausted account.

On appeal, the Federal Circuit agreed with the patentee that the claim did not require that any accounts actually be exhausted. Rather, the claim only requires a particular action if the accounts are exhausted.

On the second point, however, the Federal Circuit agreed with the accused infringer — finding that "nothing in the record" shows that Transamerica uses a computer system to make scheduled payments once an account has been exhausted.

Legal Obligation to Infringe: As an interesting tid-bit, Transamerica's contracts apparently do required the company to continue making scheduled payments even after its accounts had been exhausted.  The Federal Circuit rejected the legal obligation as proof of infringement — holding instead that the claims require computer implementation of the method. Furthermore, a contractual obligation to perform a method does not constitute infringement. Rather, infringement requires performance: "A contractual obligation to perform an act is not performance; indeed, a party could avoid infringement simply by breaching its contract."

Non-Patentable Subject Matter: Based on its non-infringement holding, the Federal Circuit left the Section 101 question undecided as moot.

Submitting Positive Decisions to the World Patent Offices

A large number of US patent applications have corresponding applications being examined in various office actions around the world. Although the major Patent Offices generally give no legal deference to the decisions of another Office, it makes sense that the decision of a first-examining Office would at least inform the analysis of the second-examining Office.

On that note, is it a regular practice of patent applicants to highlight the positive actions of other offices (such as the allowance of parallel claims)? Are there certain worldwide offices where this type of submission is more common?

Terminal Disclaimers and PTO: Proposal for a Test Case

Obviousness-type non-statutory double patenting is a judicially created doctrine that operates to prevent patentees from improperly extending a patent's effective term through successive patent grants.

The non-statutory double patenting doctrine was created at a time when patent term was measured from the grant date. At that time, it was easy to "play games" with the patent terms by using a series of continuation applications. Because patent term (for new patents) is now defined by the filing/priority date, most of the potential for games has been eliminated because a family of related applications will typically have the same term. However, a growing issue is patent term adjustment (PTA) that increases the patent term for applications with long prosecution pendency. Because of the increased backlog and changes to PTA calculations, it is likely that later-issued applications in a family will have a longer PTA.

Courts and the PTO have agreed that a patentee can overcome a non-statutory double patenting problem by filing a terminal disclaimer that ties the patent-term of a later-granted patent to the patent term of an earlier-granted patent.

The impact of a terminal disclaimer depends upon what was actually disclaimed. Although applicants can draft their own terminal disclaimer, most folks use the form provided by the USPTO. (SB-0025). The PTO Form disclaims the term of the later-issued patent that extends beyond the earlier-issued patent's term. Regarding PTA, the Form expressly ties the later-issued patent's term to the PTA-adjusted term of the earlier-issued patent.

Although not expressly stated, the Form seems to imply that the PTA of the later-issued patent can be cut-short by the disclaimer. That result, however, is not compelled by the law. In theory (and largely in practice) PTA is based on patent office delay. As such, the equitable basis of the non-statutory double patenting doctrine might not apply to require disclaimer of PTA.

A patent applicant may want to pursue a test-case by modifying the terminal disclaimer form to expressly state that the disclaimer does not cut short the PTA of that later-issued patent. Thus, the term of a later-issued patent with a 400-day PTA and a terminal-disclaimer would limited to the term of the earlier-issued patent plus 400-days.

 

SGI v. AMD: Chief Judge Rader on Claim Construction

Silicon Graphics, Inc. (SGI) v. ATI Technologies, Inc. and Advanced Micro Devices (AMD) (Fed. Cir. 2010)

In his first opinion as Chief, Judge Rader provided the parties with a lesson in claim construction. This decision is a case-in-point for the high value of professional patent drafting because the decision turns on the esoterics of claim construction. This decision also highlights the primacy of claim construction in the infringement analysis. Namely, the question of whether ATI chips infringe was boiled-down into an interpretation of the claim language.

SGI’s patent is directed to graphics processing hardware that uses floating point calculations.

Meaning of “A”: The asserted patent claims include “a rasterization circuit . . . that rasterizes the primitive according to a rasterization process which operates on a floating point format.” Although the accused ATI chips do use floating point numbers, the ATI rasterization process also uses fixed-point numbers. The district court held that the ATI chips could not infringe because their rasterization process does not operate in floating point format “as a whole.”

On appeal, the Federal Circuit re-parsed the claim language and rejected the district court’s construction as erroneous. Rather, the fact that a circuit rasterizes using fixed point format does not preclude the circuit from also using “a rasterization process which operates on a floating point format” as required by the specification.

The use of the indefinite article “a” in the claim, when coupled with the list of processes provided in the specification, makes it clear that the claims’ references to “a rasterization process” means “one or more rasterization processes.”

The limitation “a rasterization process which operates on a floating point format” therefore means that “one or more of the rasterization processes (e.g., scan conversion, color, texture, fog, shading) operate on a floating point format.” This construction is also in line with the rest of the specification. Nowhere does the specification teach that all rasterization processes must operate on a floating point format.

Summary of the Invention: The claim also requires that the rasterization circuit perform “scan conversion.” The district court required that the scan conversion be accomplished entirely using floating point numbers. On appeal, the Federal Circuit agreed with that interpretation. In making its decision to limit the breadth of the term, the court looked to a statement from the Summary of the Invention that: “the scan conversion process is now handled entirely on a floating point basis” and another statement from the specification that “this rasterization process is performed exclusively in a floating point format.” In several places, the specification indicated that various operations could be performed using fixed point numbers. However, the court held those statements insufficient because they were never specifically directed to the scan conversion process. “Thus general language in the specification permitting some operations to be done in fixed point does not work to contradict the specific language that requires scan conversion in floating point.”

Beating the Deadline: Timing the Responses to Non-Final Office Actions

PatentlyO060

I took a sample of 6,600 published patent applications whose prosecution files each included an initial non-final office action rejection and a response to that action that was submitted sometime between January 1, 2008 – June 10, 2010.  Based on the dates of the office action and response, I created the histogram shown above. (Note, the histogram is corrected for due-date shifts caused by weekends and holidays).  The data is an improvement on what I presented in 2008. [Link]

As the chart show, patent applicant responses are extremely deadline driven. A typical non-final office action allows three-months to respond, but that deadline can be extended for up to three more months (for a fee).  The current extension fees are $130, $490, and $1,100 for one, two, and three month extensions respectively. That fee is cut in half for qualified “small entities.”  About 2/3 of applicants respond within the original three-month deadline. An additional legal reason to meet the original three-month deadline is that it preserves potential patent term adjustment (PTA) created by patent office delays. PTA is reduced by one-day for each day of applicant delay beyond the three month date.

Hitting the Deadline: More than 26% of the responses were filed on the exact day of the three month deadline. For applicants that missed that date, 70% filed their responses within four-days of a deadline.

Compact Prosecution: One problem with long delays is that information regarding the invention, the business needs, and the prior art, and the attorney-examiner relationship all become stale in the course of three months.  Although this staleness is difficult to quantify, I did look at patent grant rate as a function of the timing of responses. In my study, I found a clear and significant negative correlation between grant rate and delay in responding to the non-final office action.  I.e., longer delays are associated with a lower grant rate. (Here, grant rate is calculated as the number of patents issued divided by sum of the number of patents issued and applications abandoned).  The chart below groups applications according to the earliest deadline met in their first OA response and reports the grant rate for each group.

PatentlyO061

Satisfied With Delay: A delay in applicant response more-likely-than-not will delay the eventual issuance of the patent.  These figures show that most applicants are not troubled by that delay. On that note, I found that applicants that claim priority to a provisional application tend to have longer delays in responding to office actions. That is not surprising since the filing of the provisional already indicates that the applicant is comfortable with delay.  As might be expected, applications relating to Biotechnology and Organic Chemistry (TC 1600) tend to have a longer delay as well.

 

When Can a Digital File be a “Product” under Section 271(g)?

Yangaroo v. Destiny Media Techmap_can_usa.jpg (E.D. Wisc. 2010)

In an interesting trans-national infringement case, Judge Griesbach awarded summary judgment of non-infringement in favor of the accused infringer. The court held that the Canadian-based defendant’s actions did not qualify as infringement under Section 271(g)’s proscription against importation-of-a-product-made-by-a-patented-process.

35 USC 271(g): Whoever without authority imports into the United States or offers to sell, sells, or uses within the United States a product which is made by a process patented in the United States shall be liable as an infringer. . .

The asserted patent claims a particular method of distributing a content file over a network. After a series of steps, recipient terminals are provided with access to the content file. The accused infringer (Destiny) distributes encrypted music files using a method that (arguably) would infringe the patent under 271(a) if it had been performed within the US. The focal-point of the 271(g) dispute here was on whether the digital music files could be considered “products” within the meaning of 271(g).

Some prior cases:

  • Bayer AG v. Housey Pharm., Inc., 340 F.3d 1367, 1371-72 (Fed. Cir. 2003) (271(g) applies only to “physical products” and does not extend to “information” produced by a patented process.).
  • NTP, Inc. v. Research In Motion, Ltd., 418 F.3d 1282 (Fed. Cir. 2005) (citing Bayer and holding that email packets sent from Canada were not “products . . . [b]ecause the ‘transmission of information,’ like the ‘production of information,’ does not entail the manufacturing of a physical product . . . .”).
  • CNET Networks, Inc. v. Etilize, Inc., 528 F. Supp. 2d 985 (N.D. Cal. 2007) (transmission of electronic catalog of product information could be a “product” within the meaning of 271(g); distinguishing NTP and Bayer as involving “services” and “information” rather than “products” and stored data).
  • Ormco Corp. v. Align Technology, Inc., 609 F. Supp. 2d 1057 (C.D. Cal. 2009) (a three dimensional digital representation of teeth transmitted to recipients in the United States was a product).

Present Decision: In Yangaroo, the court distinguished CNet and Ormco by holding that the distributed music file was not a “product” of the method because the music file was not created by the claimed process.

Notes:

  • The Defendant (Destiny) did modify the music files during its distribution process by encrypting them. The district court held that the newly encrypted files could not be considered 271(g) products because the asserted patent did not claim encryption.
  • Ted Sabety handled the defense.

False Marking: Solo Cup Properly Rebutted Presumption of Intent to Deceive

Pequignot v. Solo Cup (Fed. Cir. 2010)

Over the past year, hundreds of companies have been sued for false patent marking. The qui-tam style statute creates a cause of action against manufacturer who, with intent to deceive the public, mark unpatented products as patented. Any person may sue to collect the damages, however, half of the award goes to the Federal Government. Damage awards may be awarded up to $500 per falsely marked article.

35 USC 292(a): Whoever marks upon, or affixes to, or uses in advertising in connection with any unpatented article the word “patent” or any word or number importing the same is patented, for the purpose of deceiving the public; or Whoever marks upon, or affixes to, or uses in advertising in connection with any article the words “patent applied for,” “patent pending,” or any word importing that an application for patent has been made, when no application for patent has been made, or if made, is not pending, for the purpose of deceiving the public – Shall be fined not more than $500 for every such offense.

Most of the pending false-marking cases have a similar factual underpinning: The product being sold is marked was covered by a patent, and the manufacturer continued to mark the products as patented even with knowledge that the patents had expired. Solo cup made two separate arguments as to why these facts are insufficient to prove false marking: (1) that a product covered by an expired patent is not “unpatented” as required by the statute; and (2) that the fact of patent expiration is insufficient to show an intent to deceive the public.

Unpatented Article: Without question, a patented article is “unpatented” once the associated patents expire.

As the district court pointed out, “[a]n article that was once protected by a now-expired patent is no different [from] an article that has never received protection from a patent. Both are in the public domain.”

The court recognized that expiry dates are often difficult to calculate:

[D]etermining the expiration date of a patent can, at times, be difficult. The date of the patent grant is shown on the first page of a patent, but its term currently also depends on the date it was filed; in 1994, the effective term of a patent changed from seventeen years commencing at issuance to twenty years from filing. Furthermore, the term depends on whether there are patent term adjustments and whether the patent owner has paid maintenance fees. Thus, as with a never-patented article, an article marked with an expired patent number imposes on the public “the cost of determining whether the involved patents are valid and enforceable.”

Solo’s products that were once covered by now-expired patents are therefore “unpatented” within the meaning of the statute.

Rebuttable Presumption of Intent to Deceive: On appeal, the Federal Circuit held that a rebuttable presumption of intent to deceive is created when a manufacturer prints expired patent numbers on its products with knowledge that the patents are expired. However, this level of evidence leaves only a “weak” the presumption of intent that can be easily rebutted.

Here, the Federal Circuit agreed that Solo Cup did indeed rebut the presumption by providing “credible evidence that its purpose was not to deceive the public.” In particular, the court held that rebuttal evidence was provided by Solo Cup’s “good faith reliance on the advice of counsel” (who said that Solo need-not remove the expired patent listing) and “out of a desire to reduce costs and business disruption.”

Holding: No violation.

This decision will put a damper on the false-marking claims. However, some defendants may not have the same advice-of-counsel excuse.

Jon Dudas New President of FIRST — the Youth Robotics Leader

JonDudasFormer PTO Director Jon Dudas has taken an interesting new job as President of the non-profit organization FIRST (For Inspiration and Recognition of Science and Technology) (www.usfirst.org). FIRST was originally founded by Dean Kamen and has the goal of helping youth find inspiration and career pathways in science, technology and engineering.

More than 200,000 students competed in FIRST robotics and technology competitions in the past year.  Kamen sees these technology initiatives as an alternative to sports. Kamen: “Not every kid wants to be a professional engineer, but they deserve the opportunity to get a taste of the world of science, engineering, technology and problem-solving. It ought to be at least as accessible to every kid as any sport. . . . Bounce, bounce, throw’ is a nice thing to get good at, but it’s not going to change security, healthcare environmental issues, or quality of life.”

Jon Dudas has been a partner at Foley & Lardner since leaving the PTO in early 2009. 

Timing of the Notice of Allowance, Issue Fee Payment, and Patent Issuance

A Patently-O reader asked a question about the timing of a patent’s issuance and whether the date of issue-fee payment affects the issue date.  i.e., whether “the patent will issue on the same day regardless of whether the issue fee is paid immediately after receiving the notice of allowance or waiting until the statutory deadline to pay.  Any thoughts?”

To answer this question, I pulled-up the file histories for 630 patents issued on June 8, 2010 and created a table comparing the respective dates of (1) the notice of allowance, (2) payment of the issue fee, and (3) issuance of the patent. I limited the sample to include only payments made within the statutory three-month window. Some file histories included multiple notices of allowance. For those, I only looked at the last-mailed notice.

Answer: As the charts shows below, the timing of issuance is closely correlated with timing of the payment of the issue fee. In my sample, 88% of the patents issued within 6–8 weeks of payment of the issue fee. Those that took longer were, for the most part, associated with older applications.  In addition, the delay was greater for applicants that waited until the deadline to pay the issue fee.

PatentLawPic1002

The second chart shows a histogram of delay from the payment of the issue fee until patent issuance. Most patents issue in the sixth-week after payment.

PatentLawPic1003

The final chart shows patent applicant delay in payment of the issue fee. The chart was created by comparing the date of issue fee payment to the three-month payment deadline. More than 50% of applicants waited until the the week of the deadline to pay their issue fee. Why the delay?

Patent Grants Remain at All-Time High

The USPTO issues patents each Tuesday morning at 12:01 am. In the past several weeks, I have reported on the rising number of patents being issued each week. The past seven-weeks rank as the top-seven weeks of all time in terms of the number of utility patents issued.

PatentlyO058

Policies and Procedures: Over the past year, the PTO has increased its weekly patent grant count by more than 30%. During that time, the PTO did not increase its budget or hire a significant number of patent examiners. The difference appears to come from two avenues: (1) changes in PTO policies and procedures that provide patent examiners more opportunity to find patentable claims and (2) changes in patent applicant behavior in favor of accepting narrower claims.

The Backlog: The rising number of grants is at least slowing the growth of the application backlog. However, it does not appear to be sufficient to actually shrink the backlog. About 8,750 utility applications are filed each week — a figure greater than the average weekly final disposals (issued patents + abandoned applications). Using the increased grant-count and a 60% allowance rate, I calculate about 7,600 such final disposals each week.  

Claim Construction Internal Consistency

PatentLawPic1001Haemonetics v. Baxter Healthcare (Fed. Cir. 2010)

This decision is important for its endorsement of the claim construction canon that the internal logic and grammar of an individual claim takes primacy over inter-claim consistency.

Haemonetics’ asserted claim was directed to: 16. A centrifugal unit comprising a centrifugal component and a plurality of tubes . . . with the centrifugal unit having a radius between 25 and 50 mm and a height between 75 and 125% of the radius.

The preamble of Claim 16 clearly indicates that the centrifugal unit includes both a centrifugal component a plurality of tubes. However, other claims and the specification indicate that the centrifugal unit did not include the tubes. 

On appeal, the Federal Circuit held that the clarity of Claim 16 controlled the term’s construction for that claim.  Regardless of its use elsewhere, in claim 16, the centrifugal unit includes the tubes.

[C]laim 16’s beginning and, in our view, controlling language could hardly be clearer. Claim 16 states: “A centrifugal unit comprising a centrifugal component and a plurality of tubes . . . .” It does not merely state the intended field of use in a preamble, as Haemonetics argues. Rather, it unambiguously defines “centrifugal unit” as “comprising” two structural components: a centrifugal component and a plurality of tubes. The claim then further recites, not the centrifugal component and not a centrifugal unit, but “the centrifugal unit” as “having a radius between 25 and 50 mm and a height between 75 and 125% of the radius.” Reading “the centrifugal unit” in the context of the dimensional limitations to refer exclusively to the vessel, as the district court did, ignores the antecedent basis for “the centrifugal unit,” and fails to give effect to the claim language “comprising a centrifugal component”.

. . .

The patentee’s inconsistent use of identical height and radius limitations for two different embodiments thus indicates that “the centrifugal unit” inthe context of the dimensional limitations must have different meanings in the context of different claims. (internal citations omitted)

The Massachusetts-based district court had reached the opposite conclusion. Based on the erroneous construction, the Federal Circuit vacated the jury verdict and remanded for a new application of the facts.
