Mayo v. Prometheus: Medical Methods and Patentable Subject Matter at the Supreme Court

Mayo v. Prometheus Labs., (on petition for writ of certiorari 2009)

The Mayo Clinic has filed a petition asking the Supreme Court to hear its case challenging the patentable subject matter of Prometheus Labs’ patents that cover a method of optimizing the dosing of a drug. U.S. Patents 6,355,623 and 6,680,302.

The invention basically offers an iterative approach to dosing that involves three steps: (1) administer a drug to a subject; (2) then determine the level of drug in the subject; and (3) decide whether the next dose should be the same, higher, or lower. The decision on the next dose is made by comparing the the level of the drug in the subject against predetermined thresholds. Claim 1 of the ‘302 patent adds additional detail including identifying the active ingredient (6-thioguanine), the diagnosis (a GI disorder), and the predetermined thresholds (e.g., 230 pmol of drug per 8108 red blood cells). Claim 46 of the ‘623 is a broad claim in that it does not not require the administration step (step 1 from above).

Broad Functional Language: You’ll note that the claims are written in broad functional language without tying the the claimed methods to any particular technology. Thus, the “administering” step could potentially be accomplished by any effective method (that has or will be invented) of getting the drug into the subject. Likewise, the patent offers potential methods of “determining the level” of drug in the body (e.g., liquid chromatography) but the claim is broadly written to seemingly cover any mechanism that fulfills that method.

Novelty Involves the Mental Step: Of course, the general iterative process is well known, what makes the Prometheus claims novel is that they identify the particular thresholds that are important (e.g., 230 pmol). In practice, the process of comparing the thresholds to the subject’s drug level is done in the mind of a physician. As Mayo explains, this merely involves the physician’s mental recognition of a natural correlation between metabolite levels and patient condition.

With these facts in mind, Mayo presents the following question: Whether 35 U.S.C. § 101 is satisfied by a patent claim that covers observed correlations between patient test results and patient health, so that the claim effectively preempts all uses of these naturally occurring correlations.

The Federal Circuit held the method patentable under its Bilski test by finding that the required administration of the drug transformed an article into a different state or thing — essentially creating a per se rule that a method requiring administration of a drug will be deemed patentable subject matter under Section 101. The court also held that the “determining the level” step was necessarily transformative since “those levels cannot be determined by mere inspection.”

Chances for Supreme Court Review: The fact that Bilski – another Section 101 case – is already pending before the Supreme Court does not mean that the court will reject this case. Rather, the court has often granted certiorari in tandem. The Supreme Court has regularly used case clustering in the past when considering patent issues: Nonobviousness (John Deere (1966), Adams (1966), & Anderson’s-Black Rock (1969)); Patentable subject matter (Flook (1978), Charkabarty (1980), Diehr (1980)); Prosecution history estoppel (Warner-Jenkinson (1995) & Festo (2000)).

The case also represents a growing trend of pitting patient advocates (who want cheaper access to medicine) against innovators (who create better medicine).

Notes & Documents:

Claim 1 of the ‘302 patent: A method of optimizing therapeutic efficacy for treatment of an immune-mediated gastrointestinal disorder, comprising:

   (a) administering a drug providing 6-thioguanine to a subject having said immune-mediated gastrointestinal disorder; and

   (b) determining a level of 6-thioguanine or 6-methyl-mercaptopurine in said subject having said immune-mediated gastrointestinal disorder,

   wherein a level of 6-thioguanine less than about 230 pmol per 8108 red blood cells indicates a need to increase the amount of said drug subsequently administered to said subject and

   wherein a level of 6-thioguanine greater than about 400 pmol per 8108 red blood cells or a level of 6-methyl-mercaptopurine greater than about 7000 pmol per 8108 red blood cells indicates a need to decrease the amount of said drug subsequently administered to said subject.

Does a Reference’s Priority Claim to a Provisional Application Alter its 102(e) Prior Art Date?

In re Giacomini (Fed. Cir. 2009) (discussion of the briefs)

Giacomini is appealing the BPAI’s 102(e) rejection — arguing that the patent asserted as prior art does not actually qualify as prior art. Giacomini’s application claims priority back to November 2000. The asserted prior art patent issued in 2006, but was filed in December 2000. The prior art patent also claims priority to a provisional application filed in September 2000. The PTO claims that the 102(e) date of the patent is the filing date of the provisional — thus making it prior art over Giacomini.

When a patent is asserted under 102(e)(2), the patent’s filing date is considered the priority date. In the language of the statute, the PTO must consider whether the putative prior art patent was “granted on an application for patent … filed in the United States before the invention by the applicant for patent.” The provision makes clear that a patent claiming priority to an international application will be given the international application filing date if that application “designated the United states and was published . .. in the English Language.” Under US case law, when being considered as prior art, divisional and continuation patents are also given the filing dates of their parents as their 102(e) date. See In re Klesper (CCPA 1968)(“provided the disclosure was contained in substance in the earliest application”). However, patents claiming priority to a foreign filing under Section 119 are not given the foreign priority date.

The novel question here on appeal is how to interpreted the statute’s silence regarding provisional applications.

Misuse of a Patent Pool: En Banc Federal Circuit To Decide Whether CD-R/RW Patentees Improperly Sequestered Alternative Technologies

Princo Corp. v. International Trade Commission (ITC) (Fed. Cir. 2009)

The long-running Princo cases involve questions of when bundled licensing of patent rights may be seen as patent misuse (and thus rendering the patents unenforceable). The underlying pools of patents cover compact discs that are recordable (CD-R) and re-writeable (CD-RW).

In its most recent panel decision, the Federal Circuit (Judges BRYSON, GAJARSA, and DYK) rejected several theories of patent misuse, but remanded to consider whether the patentees has improperly sequestered alternative technologies. Judge Bryson did not agree with the novel misuse theory and dissented-in-part. Princo, US Philips, and the ITC each requested rehearing en banc.

The Federal Circuit has now granted the requests from US Philips and the ITC to hear the case en banc. (The court rejected Princo’s request for rehearing its questions en banc).

US Philips presented two questions:

  1. Whether a supposed agreement, between developers of new technology and a new product standard, to license one of the resulting patents only for use under that standard, thus foreclosing the possibility that it might be used to create a competing standard, could be held anticompetitive without (i) defining a relevant market in which the standards compete and (ii) proving that the agreement injured or was likely to injure competition in that market.
  2. Whether such an agreement, even if deemed anticompetitive, would be a proper basis for invoking the doctrine of patent misuse to refuse enforcement of different patents used to practice the joint standard.

The ITC did not explicitly list its en banc question, but basically argues that the remand is improper because (1) neither party raised the misuse theory that the court relied upon in its decision and (2) the ITC needs the Federal Circuit to define the “relevant market” before it can properly determine the market harm.

Briefs: US Philips en banc brief will be due at the end of November, and briefs from the ITC and Princo will be due thirty days from the date of service of US Philips. “Briefs of amici curiae will be entertained, and any such amicus briefs may be filed without leave of court but must otherwise comply with Federal Rule of Appellate Procedure 29 and Federal Circuit Rule 29.”

US Philips is represented by Douglas Melamed at WilmerHale; Princo is represented by Eric Wesenberg at Orrick; the ITC’s lead attorney is Clara Kuehn. Portions of the Melamed and Calebresi 1972 article on property rights is found in almost every property law casebook.

Bilski Briefs: Supporting the Government (In Name)

UPDATE: More briefs added Oct 5, 2009, 11:30 am

The final round of amicus briefs have been filed in the pending Supreme Court case of Bilski v. Kappos. Mr. Bilski is appealing the Federal Circuit's en banc rejection of his patent application. In that decision, the court held that Bilski's claimed method of hedging risk did not qualify as patentable subject matter under 35 U.S.C. 101 because the method was neither tied to a particular machine nor transformative of any physical article. Bilski challenges this "machine-or-transformation" test as unduly narrow. Bilski's legal position was supported in a large set of amicus briefs including a strong textualist argument made by Professor John Duffy.

Briefs supporting the government position have been filed. As summarized below, the vast majority of briefs also reject the Federal Circuit's machine-or-transformation test as the sole test of patentable subject matter for a claimed process. In my summaries, I have attempted to capture what I learned from each brief, of course the briefs and arguments are much more extensive and nuanced than my squibs suggest.

Electronic Frontier Foundation (EFF) and the Kauffman Foundation: Business method patents are harmful and should not be allowed. The long history of US patentable subject matter indicate that a patentable process must provide a technological advance. Likewise the mere fact that a process uses a machine or computer does not immediately render the process patentable subject matter. Rather to be patentable, the advance must be a technological advance. EFF etc amicus brief.pdf.

Law Professors and the AARP (Including Josh Sarnoff): Patents should only cover "inventions in the application." Patents can not cover "non-inventive applications of public domain science, nature, and ideas." The right interpretation of the statute requires that the invention "reside in the application, rather than in a discovery preceding or employed by it. This is because the science, nature, or ideas must be treated as if they are already in the prior art, i.e., are publicly known and free for all to use. Absent invention in applying such discoveries, there is simply no invention to patent." 08-964 bsac Brief of Eleven Law Professors and AARP.pdf.

Microsoft, Philips, and Symantec: Nobody (except Bilski) believes that his claims deserve patent rights. The machine-or-transformation test should not be seen as the exclusive test of patentable subject matter of a process claim – in part because the test has already "proven overly difficult to implement in practice." Like Professor Hollaar, Microsoft would simplify the test by requiring that the invention "involve one or more disclosed physical things." Today's computers – although complex – are not fundamentally different from Babbage's 1836 mechanical computer. Process claims that use computers should be patentable. Am Brief.pdf.

Professor Hollaar and the IEEE: Just restating the general principles of patentable subject matter is unhelpful. Rather, clear rules are needed – especially because the subject matter question is most frequently addressed by patent examiners who have little legal training and little time to ponder abstractions. A clear and time-tested rule would be: A process is patentable subject matter when it involves making or using a machine, manufacture, or composition of matter. This means that software method patents that require a computer would be patentable, but Bilski's method of hedging would not be patentable. bilski-sc-amicus.pdf.

American Medical Association: The machine-or-transformation test should not supplant the requirement that a patent claim "address a technology." A patent should not be allowed to cover "every possible application of a scientific observation." Rather, claims should be limited to "a particular new and useful application or use of the observation. The Supreme Court should use this case to make a statement especially directed to "overreaching claims in the life sciences. . . . Such patents chill research, and patents such as those in Labcorp and Prometheus chill talking and thinking of ideas by making talking and thinking into a tort." 08-964 bsac The American Medical Association.pdf.

Adamas Pharma and Tethys: Section 101 should be interpreted in a way that is objective, predictable, and not duplicative of the other patentability requirements. The machine-or-transformation (MoT) test does not meet any of these requirements. The Federal Circuit test also violates US treaty obligations under TRIPS and NAFTA and potentially subject the US to trade disputes adjudicated at the World Trade Organization (WTO). Under these US-initiated treaties member countries agreed to offer patent rights "in all fields of technologies." A major purpose of the agreements was to ensure that countries offered a full scope of patent rights, and by limiting the scope of rights, the US "will no longer be able to credibly argue in Special 301 trade disputes that failure to protect healthcare inventions made by cutting-edge U.S. companies constitutes inadequate protection of intellectual property rights." Some Congressional intent can be gleaned from the legislative history of Section 287(c) of the patent act. As originally proposed, that provision would have limited the subject matter eligibility of medical and diagnostic methods. After some debate, a compromise was reached to continue to allow their patenting, but to limit the remedies available. 08-964 bsac Adamas Pharmaceuticals.pdf.

Robert Sachs and Daniel Brownstone: Software should be patentable and has been for a long time. The Federal Circuit test greatly confuses the issue. Although software is an abstraction from the physical world, it is not "abstract." SF-5270929-v1-Bilski_v_Doll_Amicus_Brief_of_R_Sachs_and_D_Brownstone_as_amici_curiae_2009-08-06.PDF.

Big Internet Retailers, including Crutchfield, Overstock, and LL Bean: Patent Trolls are hurting online retailers and one way to stop them is to eliminate business method patents (including software business method patents). In effect, business method patents amount to a tax on Internet commerce. (The companies don't mention – unlike offline retailers – internet companies are often exempt from paying sales tax…) Internet Retailer Amicus Brief.pdf.

Brief of CASRIP (U. Washington): The US Constitution sets a bound on the scope of patentable subject matter – limiting them to the Constitutionally proscribed "useful Arts" as that term was understood at ratification. For new methods, one key is to consider the purpose of the method. Methods of entertaining a cat using a laser and telling a joke into a microphone should not be patentable regardless of their tie to particular machines because neither of those functions have ever "been considered a useful Art, and surely . . . is not the kind of discovery that the Patent Clause contemplates." Some methods also exist that should be patentable even though they fail the machine-or-transformation test. Despite its problems, the machine-or-transformation test is "superior to its competitors in filtering out preemptive claims to basic principles." However, it should not be the sole test of eligibility. Bilski's claim is unpatentable because hedging against price inflation (the purpose of the method) is not within the useful Arts.

Public Accessibility of Prior Art: PTO Must Provide Evidence of Indexing Date

In re Lister (Fed. Cir. 2009)

Lister is attempting to patent his method of playing golf that allows a player to tee-up each shot (except for hazards and greens). He filed his patent application in 1996. Two years prior, however, Lister had registered a copyright on his manuscript describing the game (acting pro se).

Based on the copyright submission, the examiner rejected the application as anticipated under Section 102(a) and barred under Section 102(b). The Board, however, eliminated the Section 102(a) rejection because “[Dr.] Lister could not have disclosed his own invention before he invented it.” However, the board did agree that manuscript’s availability at the copyright office did constitute prior publication under the statutory bar of Section 102(b). The touchstone for publication under Section 102(b) is public accessibility.

[The Board] concluded that an interested researcher would have been able to find the manuscript by searching the Copyright Office’s catalog by title for the word “golf” in combination with the word “handicap.” Additionally, the Board found that an individual seeking to view the manuscript would have been able to do so by visiting the Copyright Office. Finally, the Board rejected Dr. Lister’s arguments that the inconvenience of visiting the Copyright Office and the Copyright Office’s rules prohibiting individuals from making copies of the manuscript precluded a finding of public accessibility. With respect to the unavailability of copies, the Board found that the inventive concept was straightforward enough that it could be understood and retained by a person of ordinary skill in the art upon reading the manuscript without any need to obtain a copy.

Although there was no evidence that anyone actually looked at the manuscript, the Board held that public accessibility does not require that the document have been actually accessed.

On appeal, the Federal Circuit reversed – finding that (1) the availability of a manuscript in the copyright office does not necessarily meet the accessibility requirement of Section 102(b); and (2) in this case, the PTO did not prove that the document was publicly accessible.

This case is akin to other “library” cases where prior art is found covered in dust in a secluded section of a library. In those cases, the material is considered public if “it could be located by persons interested and ordinarily skilled in the subject matter or art exercising reasonable diligence.”

Here, the court found that the Library of Congress records did not create accessibility because those records were (at that time) not searchable by subject or keyword. Rather the LOC records could on be searched by title (beginning with the first word of the title of the article) or author last name.

The automated catalog was not sorted by subject matter and could only be searched by either the author’s last name or the first word of the title of the work.

On the other hand, LOC records (although not the full manuscript text) are also available through Westlaw and Dialog. In its decision, the appellate panel indicated that the search features available through those paid services were sufficient to make the records “publicly accessible.” However, the record did not indicate when Lister’s records became available through Westlaw or Dialog and thus those sources cannot be relied on as prior art.

Absent evidence of the date that the disclosure was publicly posted, if the publication itself does not include a publication date (or retrieval date), it cannot be relied upon as prior art under 35 U.S.C. 102(a) or (b). Quoting M.P.E.P. § 2128.

. . . .

Essentially, the evidence shows that at some point in time Westlaw and Dialog incorporated the Copyright Office’s automated catalog information about the Lister manuscript into their own databases. There is no indication as to when that occurred or whether it was prior to the critical date. We see little difference between the evidence in this case and a situation in which an examiner comes across an undated reference that discloses an invention for which an applicant is seeking the patent. We surely would not view the mere existence of the reference in the latter scenario as prima facie evidence that it was available prior to the applicant’s critical date.

. . . absent any evidence pertaining to the general practices of the Copyright Office, Westlaw, and Dialog, or the typical time that elapses between copyright registration, inclusion in the Copyright Office’s automated catalog, and subsequent incorporation into one of the commercial databases, any presumption along those lines would be pure speculation.

On remand, the PTO can legitimately reject the application again if it can prove that the LOC records were available through Westlaw or Dialog more than one year prior to the 1996 patent application date.

An Initial Comment on Prometheus: The Irrelevance of Intangibility

By Kevin Emerson Collins, Associate Professor of Law, Indiana University Maurer School of Law—Bloomington [BIO][Articles][PDF Version of this Post]

Background: The Machine-or-Transformation Test of Bilski

Last fall, the Federal Circuit articulated the “machine-or-transformation” test for patent eligibility in its landmark case In re Bilski, 545 F.3d 943 (Fed. Cir. 2008) (en banc). It held that a method is eligible for patent protection only if it is either (a) limited to a “particular machine” or (b) responsible for transforming a “particular article” into a different state or thing. Id. at 954. Additionally, in a classic example of language that adds judicial wiggle room, the machine or transformation that satisfies either of these prongs “must impose meaningful limits on the claim’s scope,” it “must be central to the purpose of the claimed process,” and it must not be part of “insignificant extra-solution activity” or a “mere data-gathering step.” Id. at 961–62 (emphases added).   

The Supreme Court has accepted certiorari in Bilski, but the impending Supreme Court opinion has not stopped the Federal Circuit from issuing what is perhaps its most important case to date applying the machine-or-transformation test: Prometheus Laboratories, Inc. v. Mayo Collaborative Services. There have been two distinct types of claims that have taken center stage in recent debates over the section 101 doctrine of patent eligibility: “business methods” and what I will call “determine-and-infer methods.” The claim at issue in Bilski describes a classic business method. In contrast, Prometheus involves a determine-and-infer method. The Federal Circuit’s opinion in Prometheus opens a new window into the import of the machine-or-transformation test. Regardless of one’s views of the soundness of Federal Circuit’s reasoning in Prometheus, herein lies one of the opinion’s greatest virtues. By issuing Prometheus before the Court’s oral arguments in Bilski, the Federal Circuit has helped to clarify the stakes of the Court’s decision to sanction, reformulate, or reject the machine-or-transformation test.

Patentable Subject Matter: Federal Circuit Upholds Patentability of Drug Dosage Method Claim

Prometheus Labs. v. Mayo Clinic (Fed. Cir. 2009)

In a unanimous panel opinion, the Federal Circuit has rejected Mayo’s patentable subject matter challenge under 35 U.S.C. 101 – holding that the claimed methods for calibrating a drug dosage were properly the subject of patent protection. The lower court had found the claims invalid under Section 101.

In its decision, the Federal Circuit applied its recent Bilski precedent.

The proper inquiry under § 101 is whether these methods meet the Supreme Court’s machine or transformation test articulated in Benson and Diehr, and applied in Bilski, and, if so, whether the machine or the transformation is central to the purpose of the claims.

Of course, Bilski is now on appeal at the Supreme Court.

The claimed method is essentially an iterative testing mechanism where the treatment drug is injected in the patient and the patient’s subsequent metabolic response is measured. The next dosage is then re-calibrated based upon the measured metabolic response.

Holding: Following Bilski, the Federal Circuit ruled that the required administration of a drug “transforms an article into a different state or thing” and that the transformation was an “integral” part of the calibration method. As such, the claims satisfy the patentable subject matter test of Bilski.

To be patentable, the claim must not wholly preempt the use of a natural process. Here, the court only weakly rebutted Mayo’s argument:

The claims cover a particular application of natural processes to treat various diseases, but transformative steps utilizing natural processes are not unpatentable subject matter. Moreover, the claims do not preemptnatural processes; they utilize them in a series of specific steps.

Method of Diagnosis: The court was clear to distinguish the Prometheus claims from diagnosis claims that merely requiring data gathering and correlation rather than an injection of drugs.

The asserted claims are in effect claims to methods of treatment, which are always transformative when a defined group of drugs is administered to the body to ameliorate the effects of an undesired condition. . . .

The crucial error the district court made in reaching the opposite conclusion was failing to recognize that the first two steps of the asserted claims are not merely data-gathering steps. . . . [T]he administering and determining steps are part of a treatment protocol, and they are transformative.

Thus, this decision at least suggests that the asserted diagnosis claim in LabCorp v. Metabolite would not be patentable. That claim involved only two steps: (1) assaying a body fluid for its homocysteine level; and (2) correlating high homocysteine with a vitamin deficiency.

Despite the stated distinctions, this case could be seen as a muted challenge to the Supreme Court and especially to Justice Breyer’s dissent from the Court’s late dismissal of its grant of certiorari. In its one sentence reflection on Breyer’s dissent, the Federal Circuit opinion merely indicates that opinion’s lack of precedential value and that the claims are “different.”

In reaching its conclusion, the district court relied heavily on the opinion of three justices dissenting from the dismissal of the grant of certiorari in Laboratory Corp. of America Holdings v. Metabolite Laboratories, Inc., 548 U.S. 124 (2006) (Breyer, J., dissenting). . . . That dissent is not controlling law and also involved different claims from the ones at issue here.

The court was clear the parties did not dispute other validity issues such as obviousness or novelty, but rather focused solely on the question of patentable subject matter.

Chances for Supreme Court Review: The setup of this case makes is a good candidate for Supreme Court review especially if the Court is not fully satisfied by its Bilski decision. The Supreme Court has regularly used case clustering in the past when considering patent issues: Nonobviousness (John Deere (1966), Adams (1966), & Anderson’s-Black Rock (1969)); Patentable subject matter (Flook (1978), Charkabarty (1980), Diehr (1980)); Prosecution history estoppel (Warner-Jenkinson (1995) & Festo (2000)).

Claim Preclusion and Vitiation

Nystrom v. Trex and Home Depot (Fed. Cir. 2009)

Ron Nystrom’s patent covers a type of decking board that is shaped in a way to shed water. In a prior case, the Federal Circuit, limited the claim term “board” to cover only boards made of “wood cut from a log.” Nystrom’s case was one of the first examples of how Phillips v. AWH could be used to limit claim scope based on statements in the specification and prosecution history – even when those statements do not rise to either a disavowal of scope or definition of a term. Because the Trex’s product is a wood-composite, it did not literally infringe the asserted claims. The district court also held that Nystrom had waived its right to argue infringement under the doctrine of equivalents.

A few days after losing the first case, Nystrom filed a second lawsuit against Trex and its distributors (Home Depot, et al.). Asserting infringement under the doctrine of equivalents against a second generation of Trex products.

On appeal, the Federal Circuit has held that the second lawsuit is barred by the claim preclusion doctrine of res judicata. Following a final judgment on the merits, claim preclusion binds parties from re-litigating the merits presented and also from raising “any other admissible matter which might have been offered” on the merits. In patent law, claim preclusion only arises when the accused product in the second suit is “essentially the same” as the accused product in the first suit.

For claim preclusion in a patent case, an accused infringer must show that the accused product or process in the second suit is “essentially the same” as the accused product or process in the first suit. Foster, 947 F.2d at 480. “Colorable changes in an infringing device or changes unrelated to the limitations in the claim of the patent would not present a new cause of action.” Id. Where an accused infringer has prevailed in an infringement suit, “the accused devices have the status of noninfringements, and the defendant acquires the status of a noninfringer to that extent.” Young Eng’rs, Inc. v. U.S. Int’l. Trade Comm’n, 721 F.2d 1305, 1316 (Fed. Cir. 1983).

Notably, claim preclusion applies applies even against issues that are waived – as here – rather than contested in open court.

In the present case, Trex admits that its new products are different, but argues that they avoid infringement in the same way – namely that its boards are not “cut from a log.” The Federal Circuit recognized this as a novel question of whether the “essentially the same” requirement should focus only on the claim terms at issue in the original case:

This court has previously emphasized that the focus for claim preclusion should be on “material differences” between the two accused devices, but has not addressed directly whether the focus of the “material differences” test is on the claim limitations at issue in each particular case.

Agreeing with the accused infringer Trex, the Federal Circuit ruled that claim preclusion applies – since the second suit would involve Nystrom “attempting to prove infringement of the same claim limitations as to the same features of the accused devices.”

Vitiation: Judge Rader authored the majority opinion, which was joined by Chief Judge Michel and Judge Prost. In addition, Judge Rader filed three pages of “additional views” focusing on the doctrine of equivalents (DOE) and its sub-doctrine of claim vitiation. DOE allows a patentee to prove infringement even when an accused device is missing certain claim limitations – so long as the difference from the claimed limitation is only insubstantial. One limitation of the DOE is that does not apply where its application would “vitiate a claim limitation.”

Judge Rader argues that the two potentially inconsistent doctrines can be reconciled into a single doctrine that both focus on the “substantiality of a missing claim limitation.” In other words, Judge Rader argues that vitiation is not a separate sub-doctrine, but rather is wholly “subsumed within the test for equivalents itself.”

[C]laim vitiation, by definition, simply rewinds and replays the doctrine of equivalents test for substantiality of a missing claim limitation. Thus, a finding of insubstantial difference to show equivalency obviates any further vitiation analysis—the wholly insignificant equivalent, by definition, would not vitiate the claim. On the other hand, a finding of substantial difference renders vitiation unnecessary. Thus, the vitiation doctrine is really subsumed within the test for equivalents itself. In other words, the all elements rule is simply a circular application of the doctrine of equivalents.

The problem with this approach is the hodge-podge of law vs. fact differentiation created by the Federal Circuit. Notably, DOE is a question of fact (decided by juries) while vitiation is a question of law (decided by judges).

This case can serve to illustrate this situation. Trex argued to the district court that a finding of equivalents on a product comprised of forty to fifty percent wood would necessarily vitiate the claim language requiring the board to be “made [entirely] from wood.” The district court agreed and barred Nystrom from pursuing an infringement theory based on equivalents. Would the result be different, however, if the accused device was comprised of fifty-five or sixty percent wood? Seventy percent? Should this question be resolved by a jury, by a judge, or by both?

Google’s Patent on its GOOGLE.COM Home Page

Earlier this week, the USPTO issued a design patent to Google that covers the “ornamental design for a graphical user interface [GUI] … as shown and described.” Pat. No. D. 599,372. Design patent coverage is essentially defined by the images include in the issued patent. Here, the image looks roughly the same as the company’s ubiquitous Google.com homepage. (See image below.)

To be clear, many patent professionals would argue that it is misleading to ever simply call this “a patent.” Rather, it is a design patent. Design patents have limited scope in that they only cover ornamental designs rather than technological advances. The USPTO has been granting design patent protection for screen shots and icons for many years. However, to my (limited) knowledge, none of those design patents have ever been enforced in court. As with most design patents, it appears that during prosecution, the PTO never issued a substantive rejection based on novelty or obviousness. [UPDATE – I updated this paragraph based on messages from two of the leading design patent experts Saidman and Carani who rightly indicated that in the past several years, few design patents have been found invalid]

Dashed or “ghost” lines in the drawing indicate features that are not claimed. Thus, patent would be infringed by someone using an identical layout even if they replaced the “Google” mark with their own mark. You can note at the bottom that the design patent drawing is marked with a circle-c ©. That indicates that Google is also claiming copyright protection for this layout. In addition, in the design patent, Google indicates that it is also claiming trademark protection for portions of the layout and – perhaps – for the layout as a whole.

Although there is some conflict in the precedent, modern courts have generally allowed companies to overlap design patent, copyright, and trademark protection in the same way that a prosecutor may charge someone with multiple crimes that all stem from the same bad act. This only becomes a problem when applicants also attempt to include utility patent protection in the mix. The problem arises because inventions protected by utility patents are required to be “functional” while design patent, copyright, and trademark laws only protect “non-functional” elements. [The non-functionality doctrine varies considerably between the regimes.]

I like to think of the three regimes (design patent, copyright, and trademark) as essentially creating different rules of evidence to prove the same thing. All of the regimes have some sort of distinctiveness doctrine. For design patents, the design must be a novel and nonobvious advance; for trademark, the mark must help distinguish goods or services in the minds of consumers; for copyright, the work must be original. Likewise the elements of infringement are similar, but different enough to provide added value to someone concerned with protecting an underlying valuable asset.

Allowing overlapping protection has problems. Most notably, the ‘piling on’ effect may make it too expensive to challenge Google’s rights even if their claim to rights appears overreaching. In the criminal justice system, this has the same effect of pushing folks to plea bargain.

Google operates in part on its reliance on the fair use doctrines of copyright and trademark laws and has been a strong advocate of open access of copyrighted works (think Google books and Google’s indexing) and limited trademark rights (so that others can bid for Google ads on a competitors trade name). By relying on design patents, Google positions itself in a way that it can protect its rights based on patent doctrines while still arguing for weaker rights in those other areas.

Design patents remain in force for 14-years from the date of issue. Thus, Google’s design patent is set to expire on Sept 1, 2023.

I have taken a screen shot of the Google.com website from Sept 3, 2009. It pretty clearly would not infringe because of the differences between layout in the patent and the layout on the site.

Notes:

  • Read the computer programmer response on Slashdot.
  • File Attachment: patd599372.pdf (72 KB). Also, see Google’s patent on Google Patents.
  • It is pretty amazing that the patent lists ten inventors for that simple thing. Did each of those individuals contribute inventive material?
  • Inequitable Conduct?: According to the face of the patent, Google did not submit any prior art. The examiner found 13 largely irrelevant pieces of prior art. Google should have at least submitted a copy of its home-page from 1 year before its March 2004 application date. The screen-shot below is the Google page from one-year before its patent priority date. (via Internet Archive). The Screen Shot serves as 102(b) prior art and also serves as a non-infringing alternative for competitors.

Microsoft v. i4i: Relevance of the Pending Reexamination

[This post continues the discussion of emergency stays pending appeal that was begun here]

i4i Ltd. v. Microsoft Corp. (Fed. Cir. 2009)

Pending Reexamination: Microsoft has submitted its motion for a stay of injunctive relief pending the outcome of its appeal to the Federal Circuit.  Oddly, the first sentence of Microsoft's introduction begins with a statement that the PTO "already had provisionally rejected upon reexamination as anticipated and obvious." By 'provisionally rejected' Microsoft means that a non-final office action has been mailed out in the ex parte reexamination that it requested in November 2008 (the litigation was filed in March 2007).

The opening is odd because of its irrelevance. The vast majority of third party requests for ex parte reexaminations are granted (over 95%) and then 'provisionally' rejected (83% of those). That usual course is simply the beginning of a typically long reexamination process. Even amongst reexaminations that received a non-final rejection – most resulted in a reexamination certificate that confirmed the patentability of at least one original claim. Of course, the final resolution of the reexamination is likely years away. (The figures are based on my own study of 5,000 ex parte reexamination file histories).

The opening is also odd because, to my knowledge, the Federal Circuit has never placed any weight on the fact that a co-pending reexamination has been provisionally rejected.

Finally, the opening is odd because it does not relate to Microsoft's arguments for a stay. In particular, the company does not argue for a stay pending outcome of the reexamination. Microsoft does argue anticipation and obviousness, but those arguments are based on the district court claim construction. As discussed on Patently-O extensively last month, claim construction in court has no direct legal link with the claim construction used at the patent office during reexamination. [Link]

The reexamination request by Microsoft focuses on two prior art references: U.S. Patent No. 6,101,512 ("DeRose") is apparently 102(e) prior art because it was filed prior to i4i's application, and i4i is unable to antedate the reference and a published description of the "Rita" SGML editor. Both of these references were considered by the jury in its analysis. In addition, Judge Davis reviewed the jury determination and found no cause for a JNOV. Interestingly, Microsoft never moved for summary judgment on any of its invalidity arguments based on these references.

To be clear, Microsoft's brief is still well written and presents compelling arguments. The only problem is that its first argument may lead the court astray. A ruling is expected prior to the October 10.

  • As the role of reexaminations continue to rise as a litigation strategy, understanding the interplay and conflict between Federal Court decisions and USPTO decisions will become critical.  Important questions involve: waiver; preclusion; and deference.

Dependent Claim Improperly Held Obvious (When Independent is Nonobvious)

PatentLawPic746Callaway Golf v. Acushnet, 2009–1076 (Fed. Cir. 2009)

Inconsistent Verdict: The jury found eight of Callaway’s golf ball claims valid – all except for dependent claim 5. According to the jury, that claim was obvious even though the broader independent claim was nonobvious.

On appeal, the Federal Circut vacated – holding that the jury verdict was “based upon irreconcilably inconsistent jury verdicts.”

Although it is true that the jury found “without reservation” that eight claims were not invalid, it is equally true that the jury found claim 5 invalid without reservation. Moreover, the evidence at trial was such that the jury could have rationally reached either verdict with regard to the asserted claims; neither party was entitled to judgment as a matter of law.

Testing Evidence: The Federal Circuit also found fault with Judge Robinson’s exclusion of evidence regarding test balls that Acushnet created based on a prior art reference and used in its anticipation argument.  The problem was that the test ball design was not fully described within a single prior art reference. However, on appeal, the court found that the needed disclosures may have been properly incorporated-by-reference within the prior art.

Material not explicitly contained in the single, prior art document may still be considered for purposes of anticipation if that material is incorporated by reference into the document. (Quoting Advanced Displays, 212 F.3d 1272 (Fed. Cir. 2000).

For anticipation purposes the incorporation-by-reference must clearly identify the material being incorporated.  Here, the court found that the prior art had done so sufficiently by referring to “foamable compositions” to be found in the incorporated reference.

Guest Post: The Applied/Abstract Distinction is the Key to §101 Patentability

Guest Post by Polk Wagner (Professor at the University of Pennsylvania School of Law)

Mark Lemley, Michael Risch, Ted Sichelman, and I have authored an amicus brief in the Bilski v. Doll case currently pending before the US Supreme Court. (Get the full brief here [pdf].) In that brief, we argue that the Court's precedents establish that the key to eligible subject matter is ascertaining whether an idea is claimed as applied–in which case it is eligible for patentability (assuming it is not a natural phenomenon or law of nature)–or merely in the abstract–in which case it is not.

We start with the proposition that while the range of subject matter available for patenting is very broad, it is not unlimited. But the restrictions imposed by the Supreme Court, we think, have not focused on the technology, form, or physicality of the claimed invention–the critical mistake made by the Federal Circuit in Bilski. Rather, the Court has uniformly recognized that the key to eligible subject matter is ascertaining whether an idea is claimed as applied, or claimed in the abstract.

This applied/abstract distinction has a long history in Supreme Court caselaw. It can be most clearly seen in the O'Reilly v. Morse case from 1854, where the Court invalidated a claim to all communication by electrical signal as abstract, but allowed a claim to the application of the communications method to stand. 56 U.S. 62, 112-21 (1854). That is, where Morse claimed the idea of communication by electrical signal, the claim was disallowed. But the Court did uphold Morse's claim to a system (e.g., "Morse Code") that applied the communication-by-electricity idea in a practical, concrete way.

One can discern the applied/abstract thread throughout twentieth-century Supreme Court decisions involving §101 subject matter. In Mackay Radio, the Court upheld a claim to a mathematical principle (related to the reception of radio waves) as applied to an antenna, noting that "[w]hile a scientific truth, or the mathematical expression of it, is not patentable invention, a novel and useful structure created with the aid of knowledge of scientific truth may be." 306 U.S. 86, 94 (1939). In Gottschalk v. Benson, the Court denied patentability to an "abstract and sweeping" claim: the mathematical conversion of binary coded decimals into pure binary format. 409 U.S. 63, 66-67 (1972). And finally, in Diamond v. Diehr, the applied/abstract approach drove the analysis–in upholding the claims, the Court noted that the subject matter was not "directed to a mathematical algorithm or an improved method of calculation but rather recited an improved process for molding rubber articles by solving a practical problem which had arisen in the molding of rubber products." 450 U.S. 175, 181 (1981) (emphasis added). Indeed, in Diehr, the Court makes our argument for us:

It is now commonplace that an application of a law of nature or mathematical formula to a known structure or process may well be deserving of patent protection. . . . Arrhenius' equation is not patentable in isolation, but when a process for curing rubber is devised which incorporates in it a more efficient solution of the equation, that process is at the least not barred at the threshold by §101.

Id. at 187-88 (emphasis in original).

We also argue that echoes of this applied/abstract distinction can be seen in the related-but-distinct caselaw considering the patentability of products of nature. Here, the Supreme Court has repeatedly emphasized in this context that the patent law is designed to protect applications of human ingenuity, not simply "natures' handiwork." Thus, while a man-made organism is eligible for patentability, see Diamond v. Chakrabarty, 447 U.S. 303, 310 (1980), a natural bacterium is not, see Funk Bros. Seed Co. v. Kalo Inoculant Co., 333 U.S. 127, 131 (1948). The boundary here is neither the form of the invention nor its ability to transform nature; instead the analysis turns on whether the patent claims describe the application of human knowledge to a practical end. In this way, a claim to an abstract idea is like a claim to a product of nature: unmoored to real-world applications of human inventiveness, and thus ineligible for patenting.

Finally, we note that the applied/abstract analytic framework nicely harmonizes Section 101 with Section 112's enablement requirement. Much like Section 101, Section 112 safeguards the essential function of the patent system: the dissemination of real-world, practical human knowledge. Claims to abstract mathematical concepts (like claims to natural products or physical phenomena) violate this tenet, by failing to demonstrate that the inventor is adding to the storehouse of useful, practical human accomplishment. (Indeed, the subject matter and enablement requirements were formerly part of the same statutory section. Patent Act of 1836, Ch. 357, 5 Stat. 117, § 6 (July 4, 1836).)

In sum, we argue that the patent statutes were wisely drafted with an expansive vision of patentable subject matter. Efforts to graft judicially created limitations onto that expansive scope in the past have proven fruitless and indeed counterproductive. This Court should not impose a requirement that patentable inventions require a machine or the physical transformation of some material. It should instead maintain the rule that patents are available for anything under the sun made by man, including discoveries of ideas, laws of nature, or natural phenomena so long as they are implemented in a practical application. In short, the test should be as it has been: where an idea is claimed as applied, it is eligible for patentability, but if it is claimed merely in the abstract it is not.

Challenging PTO Decisions in District Court: Federal Circuit Affirms Exclusion of Enablement Evidence that “Should Have” Been Raised During Prosecution

Hyatt v. Doll (Fed. Cir. 2009) 07-1066.pdf

Gil Hyatt is a prolific inventor who has spent much of his time over the past thirty years challenging the bounds of USPTO practice. This August 11, 2009 opinion marks the seventeenth Federal Circuit decision focusing on Hyatt’s patent rights in addition to the 2003 Supreme Court decision Franchise Tax Bd. of California v. Hyatt.

This Case: During prosecution, the examiner rejected each of Hyatt’s 117 computer memory architecture claims based on anticipation, obviousness, enablement, double patenting, and written description. Hyatt appealed (pro se) to the BPAI who reversed the bulk of the rejections, but affirming only the written description and enablement rejections associated with 79 claims. Hyatt then took his case to Federal Court by filing a civil action in DC District Court grounded in 35 U.S.C. 145.

At the district court, Hyatt submitted a new declaration offering additional evidence of enablement and written description. However, the district court excluded that inventor-declaration from evidence based on Hyatt’s “negligence” in failing to previously submit the information to the PTO.

On appeal, the Federal Circuit affirmed the exclusion of evidence – holding that the district court may properly exclude evidence that Hyatt should have produced to the PTO. (Chief Judge Michel as author joined by Judge Dyk)

Hyatt was obligated to respond to the examiner’s written description rejection by In re Alton, 76 F.3d 1168, 1175 (Fed. Cir. 1996), by explaining where in the specification support for each of these limitations could be found. . . . The Board noted, “It is far easier for appellant to describe where the limitation he wrote is disclosed than for the Office to prove that the limitation is not disclosed.” . . . Hyatt, however, refused to cooperate, even though he necessarily possessed the information the examiner sought by the time he filed his application.   

On these facts, the district court’s exclusion of Hyatt’s new evidence must be affirmed. . . . [I]t is clear from the record that Hyatt willfully refused to provide evidence in his possession in response to a valid action by the examiner. Such a refusal to provide evidence which one possessed was grounds in Barrett to exclude the withheld evidence. Similarly, we hold that in light of Hyatt’s willful non-cooperation here, the district court did not abuse its discretion by excluding the Hyatt declaration.

Judge Moore penned a vigorous dissent in support of the patent applicant’s right to a full civil action including the right to submit additional evidence when challenging a PTO decision.

The majority takes away this patent applicant’s fundamental right to a “civil action to obtain [a] patent” as granted by Congress in 35 U.S.C. § 145. Today the majority decides that a patent applicant may not introduce the inventor’s declaration in a § 145 proceeding before the district court because the inventor had an “affirmative duty” or “obligation” to disclose this evidence to the PTO. His failure to fulfill his affirmative duty, by not disclosing evidence he could have disclosed to the PTO, results in such evidence being excluded from the district court § 145 proceeding. The district court made no fact findings indicating willful withholding or intentional suppression; in fact, the district court did not even conclude that Mr. Hyatt’s conduct amounted to gross negligence, but rather excluded the evidence under a negligence “could have” standard. Nor did the PTO even argue, at any stage of these proceedings, that Mr. Hyatt’s conduct in this case was willful or intentional. Nonetheless, the majority concludes that the applicant “owed,” the PTO all evidence he possesses that is responsive to a rejection and that failure to fulfill this newly created “affirmative duty” amounts to willful withholding as a matter of law. There are only two possible ways to interpret the majority’s willful withholding determination. Either the majority is engaging in appellate fact finding or it is determining that breach of its newly created affirmative duty is willful withholding as a matter of law.

. . .

Congress granted patent applicants the right to a civil action in the district court distinct from their right of appeal. It is our obligation to protect the distinction Congress codified in § 145, not to reweigh the virtues of that decision. The § 145 proceeding is a civil action and ought to be governed by the same Federal Rules of Evidence that govern other civil actions. Patent cases do not need, nor should they have, special rules of evidence.

. . .

The statute itself distinguishes the appeal that may be brought pursuant to 35 U.S.C. § 141 because a § 145 action is not an appeal; it is a “civil action.” The statute obligates the district court to adjudicate the facts in this civil action. Because the statute affords no limitations on the type of evidence that ought to be admissible in a civil action brought under § 145, the standard Federal Rules of Evidence that govern all civil actions ought to govern. The legislative histories of § 145 and its predecessor statute, section 4915 of the Revised Statutes, repeatedly and without contradiction indicate that the intent of Congress was to permit a patent applicant to bring a new suit built upon a new record. . . . Congress intended that the district court in a § 145 action have everything that a court would have in an infringement suit. Under this standard, Congress certainly intended for an inventor, such as Mr. Hyatt, to be permitted to introduce his own declaration in a § 145 action.

. . .

The majority holds that by failing to offer his testimony to the PTO, Hyatt has failed to satisfy “an affirmative and specific duty.” Maj. Op. at 2. In this way, this new affirmative duty for prosecution seems to resemble inequitable conduct, though here the applicant is penalized regardless of their intent. . . . With all due respect to the majority, I do not believe a new “affirmative duty” to disclose is warranted, nor do I believe Hyatt was “required by law” or “obligated” to provide his declaration to the PTO. While Mr. Hyatt may have failed to overcome the rejections or to convince the Board based upon his submissions to the PTO, he did not fail to fulfill an “obligation” or “affirmative duty” as the majority alleges.   

. . .

In this case, the district court found that Mr. Hyatt’s failure to proffer his

declaration to the PTO was merely negligent. . . . I find troubling the majority’s characterizations of Mr. Hyatt. See, e.g., Maj. Op. at 51 (Mr. “Hyatt purposefully kept [the Board] in the dark”); id. (his “blatant non-cooperation”); id. at 50 (Mr. “Hyatt willfully refused to provide evidence in his possession”); id. (Hyatt “refused to cooperate”); id. (“Hyatt’s willful non-cooperation”); id. at 55 (“Hyatt willfully refused”); id. at 49 (providing his declaration “should have been simple for him”); id. at 55 (that Hyatt’s failure “to perform a simple task that it was his burden to perform is inexcusable”); id. at 54 (“Hyatt’s perverse unhelpfulness”). None of this appears in the district court proceedings, the PTO proceedings, or the record— these fact findings ought to be left to the district court which is in the best position to weigh the contradictory evidence.

. . .

Contrary to the appellate finding of willful withholding, the record contains ample evidence of a lack of willful withholding. Here, the examiner rejected all of Mr. Hyatt’s 117 claims for lack of written description, failure to enable, obviousness-type double patenting (over 8 separate references), and Schneller-type double patenting (over the same 8 references). The examiner also rejected 9 claims as anticipated (Hill reference) and 7 as obvious (over a combination of three references). Technically, Mr. Hyatt was appealing 45 separate issues totaling 2546 separate rejections of his 117 claims to the Board. He wrote a 129-page appeal brief addressing all of these different rejections. And, to be clear, the Board reversed all the examiner’s rejections for obviousness, anticipation, obviousness-type double patenting, Schneller-type double patenting, and many of the written description and enablement rejections. With regard to the written description rejections in particular, the Board reversed the rejections of 38 claims and sustained the rejections of 79 claims. Mr. Hyatt prevailed on 92% of all the examiner’s rejections at the Board level. Despite Mr. Hyatt’s success, the majority declares Mr. Hyatt’s response to be “completely and wholly inadequate” and Mr. Hyatt to have been perversely unhelpful. Maj. Op. at 55, 56.

. . .

Although Mr. Hyatt may have failed to overcome all of the written description rejections based upon his submissions to the PTO, he did not fail to fulfill an “obligation” or “affirmative duty,” and he certainly was not “perversely unhelpful” as the majority alleges. . . I believe the court is wrong to hold that breach of the newly created affirmative duty, i.e., not producing evidence to the PTO, is willful withholding as a matter of law.

. . .

In hindsight, perhaps Mr. Hyatt should have submitted his declaration or that of any other expert earlier in the prosecution process. But hindsight is misleadingly acute. Declarations and expert reports are time consuming and expensive to prepare. It is hardly reasonable or even desirable to require patent applicants to put massive declarations into the record at an early stage of prosecution, weighing the cost to both the applicant and the PTO. See generally Mark A. Lemley, Rational Ignorance at the Patent Office, 95 Nw. U.L. Rev. 1495 (2003) (arguing that it would be inefficient for the PTO to overinvest in examination because so few patents are enforced). In this case, for example, the examiner rejected the claims on many different bases (double patenting on 8 different references, obviousness, anticipation, enablement, written description, etc.), totaling 2546 separate rejections. The Board overturned nearly all of them. It is easy with the benefit of hindsight to say Mr. Hyatt should have introduced more evidence on written description to the Board. But Mr. Hyatt was not facing merely a written description rejection, he was facing 2546 separate rejections on many, many different bases. The majority implausibly asserts that 2546 separate rejections is “proportional to Hyatt’s prosecution of an application containing 117 pending claims spanning 79 pages.” Maj. Op. at 56 n.35. An average of 21 rejections per claim is hardly proportional. Mr. Hyatt was forced to appeal 45 independent issues to the Board when the average is two. Dennis D. Crouch, Understanding the Role of the Board of Patent Appeals in Ex Parte Appeals, 4, available at http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1423922. Despite this challenge, Mr. Hyatt was largely successful on appeal. Further, the length of Mr. Hyatt’s application suggests that his efforts to pinpoint pages containing certain terms was helpful and in good faith. Mr. Hyatt’s response may have been especially valuable in the time before searchable electronic applications.

To say that Mr. Hyatt had an affirmative duty to introduce all evidence to the Board or that he “owed” (Maj. Op. at 56) all the evidence he possessed is to put an enormous and undesirable burden on the patentee, one that will foreclose patent protection for many small inventors. Congress foresaw exactly this problem and ameliorated it with § 145 by providing applicants a way to initiate a civil action and introduce new evidence after Board proceedings when the issues are much more succinct and consolidated. This is illustrated perfectly here, where the applicant was contending with 2546 rejections on many different bases before the Board. After the Board overturned nearly all of them, only a small number of rejections—based on written description/enablement—were maintained. Hence at the district court the applicant could proffer much more extensive evidence because the universe of issues was greatly narrowed. This is the sensible approach Congress enacted. The statute even places the cost of the proceeding on the party better positioned to know the value of the application—the applicant. The majority’s new exclusionary rule based upon its new affirmative duty upsets this balance.

Notes: I expect that Hyatt will ask for reconsideration and will then push for Supreme Court review.

Blackboard: Federal Circuit Again Find Software-Related Means-Plus-Function Claims Invalid for Failing to Disclose Sufficient Structure

Blackboard v. Desire2Learn (Fed. Cir. 2009) 08-1368.pdf

Blackboard’s patent covers an internet-based educational support system and method. (U.S. Pat. No. 6,988,138). On summary judgment, the district court (Judge Clark, E.D. Tex.) found claims 1-35 invalid as indefinite, but a jury found found that Desire2Learn liable for infringement of claims 36-38. On appeal, the Federal Circuit agreed that Claims 1-35 are indefinite, and – after altering the claim construction – held that the remaining claims were also invalid as anticipated. pic-54.jpg

Means-Plus-Function: Blackboard’s seemingly broadest claim (claim 1) includes several means-plus-function clauses, including a “means for assigning a level of access and control.” The specification briefly discusses an “access control manager” (ACM) with an “access control list.” On appeal, however, the court found that brief description to be an insufficient “disclosure of the structure that corresponds to the claimed function” and consequently indefinite under 35 U.S.C. §112 ¶2. See In re Donaldson, 16 F.3d 1189 (Fed. Cir. 1994)(en banc).

“[W]hat the patent calls the ‘access control manager’ is simply an abstraction that describes the function of controlling access to course materials, which is performed by some undefined component of the system. The ACM is essentially a black box that performs a recited function. But how it does so is left undisclosed.”

Important for patent drafter, means-plus-function claims require disclosure in the specification even if the means are already well known in the art.

The fact that an ordinarily skilled artisan might be able to design a program to create an access control list based on the system users’ predetermined roles goes to enablement. The question before us is whether the specification contains a sufficiently precise description of the “corresponding structure” to satisfy section 112, paragraph 6, not whether a person of skill in the art could devise some means to carry out the recited function.

Because claims 2-35 all depend upon claim 1, they are all invalid as indefinite

Claim construction: At the trial, Blackboard’s expert could only identify one difference between claims 36-38 and the prior art. Namely, that the Blackboard patent identified a “single login” feature that allowed one user to have various roles within the system. “For example, Blackboard asserted that its claimed method would allow a graduate student who was a student in one course and a teacher in another to use a single login to obtain access to both courses and to obtain access to the materials for each course according to the graduate student’s role in each.” However, on appeal, the Federal Circuit determined that the claims do not actually require that feature — leading them to hold the claims invalid based primarily on the admissions of Blackboard’s own expert.

[O]nce the claims are properly construed, the conclusion of anticipation is dictated by the testimony of Blackboard’s own witnesses and the documentary evidence that was presented to the jury. Based on that evidence, and in the absence of a “single login” requirement in claims 36-38, it is clear that the prior art contains every limitation of those claims.

Defendant Desire2Learn wins a complete victory (after a few million in attorney fees).

Centocor v. Abbott (E.D.Tex.)

Centocor v. Abbott (E.D.Tex.)

Abbott has two chances to block the $1.67 billion jury verdict while the case is still in the hands of E.D. Texas Judge Ward.

Inequitable Conduct: Because inequitable conduct is an equitable doctrine, it is determined by a judge. In this case, Judge Ward bifurcated the trial and will hold a one-day bench trial on inequitable conduct on August 4, 2009. On the 4th, parties will each have three hours of witness time and 25 minutes for argument.

Judgment Notwithstanding the Verdict (JNOV): This is unlikely in Judge Ward’s courtroom – especially here since the Judge has already denied Abbott’s motions for summary judgment.

On appeal at the Federal Circuit look for a number of different disputes, including:

  • Priority dates and anticipation: Centocor’s patents claim priority to 1991 via a series of continuations-in-part, but the claims at issue were probably not enabled until a 1994 filing. In 1993, a foreign counterpart of the original application published – becoming prior art against the 1994 CIP filing. The appeal may focus on the symmetry (or lack therof) between enablement and anticipation.
  • Damages: The damage calculation here is somewhat complex and could lead to important Federal Circuit precedent on lost profits

Understanding the Role of the Board of Patent Appeals: Ex Parte Rejection Rates on Appeal

6a00d8341c588553ef0115704a8ff5970c-pi[1] By Dennis Crouch     PDF Version of the Article

Abstract:

This study provides an issue-by-issue analysis of decisions on ex parte appeals by the Board of Patent Appeals and Interferences (BPAI) of the United States Patent and Trademark Office (USPTO). All the cases in this study were appealed to the BPAI after one or more of the pending claims were rejected by a patent examiner. 

In the study, I report that most BPAI appeals focus on two or more issues. Of those, the majority of issues (61%) are affirmed and the remainder reversed. When more issues are presented, the case as a whole becomes more likely to be affirmed-in-part. In addition, I find that the likelihood that a case is affirmed has increased over time (Jan 2008 – May 2009).

By far, the most common issue on appeal is obviousness. I find that 87% – 90% of ex parte BPAI decisions decide an issue of obviousness. Only 4% of appeals consider neither obviousness nor novelty. The major aberration of this trend is for cases involving biotechnology and organic chemistry (TC 1600). 18% of BPAI decisions arising from TC 1600 focus on issues other than obviousness and novelty.

In comparing results by issue, I find that obviousness rejections are more likely to be affirmed than are other types of rejections. Most cases (74%) that discuss neither obviousness nor novelty are reversed.

The BPAI is becoming increasingly important. Over the past several years, the BPAI has seen a dramatic rise in the number of appeals being filed. In addition every recent patent reform legislative proposal has included an increased role for the Board.
