Glass Half Empty: Patent Reciting “Half Liquid” Is Indefinite

by | Aug 13, 2020 |

The US Court of Appeals for the Federal Circuit affirmed the district court’s finding that the asserted patent claims were invalid as indefinite because the meaning of the term “half-liquid” was not reasonably clear from the record. IBSA Institut Biochimique, S.A. v. Teva Pharms. USA, Inc., Case No. 19-2400 (Fed. Cir. July 31, 2020) (Prost, C.J.).

IBSA owns a patent directed to pharmaceutical formulations for thyroid hormones that enable a safe and stable oral administration. IBSA listed in the Orange Book the patent for Tirosint®, a soft gel capsule formulation containing the active ingredient levothyroxine sodium. Teva filed an abbreviated new drug application to market a generic version of Tirosint®, and IBSA responded by filing a lawsuit for patent infringement against Teva.

During claim construction, the parties disputed the construction of the term “half-liquid.” IBSA proposed that “half-liquid” should be construed to mean “semi-liquid,” while Teva argued that the term was indefinite or should be construed as “a non-solid, non-paste, non-gel, non-slurry, non-gas substance.” The district court began its analysis by acknowledging that the parties “agree that the intrinsic record does not define ‘half-liquid.’” IBSA argued that a priority Italian patent application’s use of the word “semiliquido” (translation: semi-liquid) in the same places where “half-liquid” was used in the patent at issue supported its position that the two terms were synonyms. The district court disagreed, noting several differences in the two patents that indicated that the different choice of terms was intentional. Further, the district court noted that the applicant originally used the term “semi-liquid” in a dependent claim during prosecution, but later removed this term, indicating that the applicant understood the terms to be different and intentionally chose not to use “semi-liquid” in the asserted claims. The district court also found IBSA’s extrinsic evidence (e.g., reliance on dictionary definitions, other patents and expert testimony) unpersuasive. The district court accordingly found the asserted patent claims invalid as indefinite because the meaning of “half-liquid” was not reasonably ascertainable from the record. IBSA appealed.

The Federal Circuit affirmed. The Court first found that the intrinsic record failed to establish the boundaries of the term “half-liquid.” The Court agreed with the district court’s analysis, finding that neither the claims nor the specification supported IBSA’s proposed construction. The Court also explained that the prosecution history reinforced the conclusion that the applicant understood “half-liquid” to be different from “semi-liquid,” because the applicant intentionally removed the term “semi-liquid” in a dependent claim during prosecution. The Court disagreed with IBSA’s suggestion that the district court refused to consider the foreign Italian priority document—rather, “when discrepancies between a foreign priority document and the U.S. filing exist, it may be proper to view the discrepancies as intentional.”

Turning to the extrinsic record, the Federal Circuit found that the district court did not clearly err in its analysis of the presented dictionary definitions, other patents and expert testimony. The Court noted that IBSA identified no scientific dictionaries containing the term despite IBSA’s argument that “half-liquid” would be a recognizable term [...]

Hooked on Precedent or Something New

by | Aug 13, 2020 |

Highlighting internal disagreement regarding patent eligibility under § 101, a divided panel of the US Court of Appeals for the Federal Circuit issued a series of opinions revising and reissuing a previous opinion on § 101 patent eligibility for a mechanical invention and, in an even split, denied a petition for en banc review. American Axle & Manufacturing, Inc. v. Neapco Holdings LLC, Case No. 18-1763 D.I. 134 (Fed. Cir. Oct. 3, 2019) (Dyk, J.) (Moore, J., dissenting); id. D.I. 133 (denying en banc by a 6–6 vote).

In October 2019, a divided Federal Circuit panel in American Axle v. Neapco affirmed a district court finding that method claims for a mechanical invention were invalid under 35 U.S.C. § 101. The majority specifically found that the claimed invention was nothing more than a recitation of Hooke’s law, which undoubtedly is a law of nature. Judge Moore dissented, arguing that the majority improperly expanded the § 101 eligibility inquiry beyond its statutory gatekeeping function and distorted patent eligibility under § 101 and enablement under § 112.

Neapco filed a petition for rehearing and a petition for rehearing en banc. Several amicus briefs were also filed. Notably, retired Judge Paul R. Michel, formerly the chief judge of the Federal Circuit, filed an amicus brief in support of the en banc petition because he believed the panel’s original decision “conflicts with the Supreme Court’s and [Federal Circuit’s] precedent.”

In view of the petition for rehearing, the original panel modified and reissued its opinion. The Court affirmed its original decision that two of the three independent claims were invalid under § 101 (patent claims 22 and 36); however, the Court reversed its original decision invalidating claim 1. Regarding claims 22 and 36, the majority reiterated that the claims were merely an application of Hooke’s law and that it was simply applying Supreme Court and Federal Circuit precedent, analogizing this case to the Supreme Court’s 1853 O’Reilly v. Morse decision where the Supreme Court determined the patentability of claims directed to a natural law of using electromagnetic force to transmit messages. When responding to the dissent, the majority reiterated that it was not departing from prior precedent, and that its “holding is limited to the situation where a patent claim on its face and as construed clearly invokes a natural law, and nothing else, to accomplish a desired result.”

Regarding claim 1, the majority reversed its original decision because the claim had an additional limitation that could cause the claim to not merely be an application of Hooke’s law. Because the district court did not address this limitation, the majority remanded the case so the district court could address this issue in the first instance.

Judge Moore maintained her dissent, arguing that the majority was announcing a new patentability test: the “Nothing More” test. She argued that the decision created a new test for instances when claims are directed to a natural law even though no natural law is specifically recited in the claims. Judge Moore further reiterated [...]

It’s Good to Be the Sovereign, Unless You Have an Exclusive Licensee

by | Aug 5, 2020 |

Addressing the interaction between state sovereign immunity under the 11th Amendment and joinder under the Federal Rules of Civil Procedure, a “fractured majority” of the US Court of Appeals for the Federal Circuit determined that an exclusive licensee could proceed with suit even though state sovereign immunity prohibited involuntary joinder of the patent owner. Gensetix, Inc. v. The Board of Regents of the University of Texas System, Case No. 19-1424 (Fed. Cir. July 24, 2020) (O’Malley, J.) (Newman, J., concurring in part and dissenting in part) (Taranto, J., concurring in part and dissenting in part).

In 2014, Gensetix indirectly licensed two patents covering cancer treatment methods from the University of Texas (UT), a state university. A subsequent confirmation between Gensetix and UT confirmed Gensetix’s exclusive license to the patents-in-suit, which required Gensetix to sue potential infringers and gave UT a secondary right to sue if Gensetix did not bring suit. The parties further agreed to cooperate regarding any infringement suit and that nothing in the agreement would waive UT’s sovereign immunity.

Three years later, Gensetix sued Baylor College of Medicine and others for patent infringement. Before filing the complaint, Gensetix asked UT, the legal patent owner, to join suit. UT declined, and Gensetix named it as an involuntary plaintiff. UT moved to dismiss itself from the lawsuit based on its sovereign immunity, and Baylor moved to dismiss because UT was a required party that could not be joined because of its sovereign immunity. The district court agreed with UT and Baylor, concluding that UT’s sovereign immunity prevented Gensetix from joining UT as a plaintiff and that the suit could not proceed without UT. Gensetix appealed.

The Federal Circuit reversed. The majority opinion, authored by Judge O’Malley, held that UT’s sovereign immunity prohibited its joinder as an involuntary plaintiff, but that Gensetix could proceed in its suit against Baylor notwithstanding UT’s absence. The Court affirmed the district court’s conclusion that UT’s 11th Amendment state sovereign immunity prohibited UT’s involuntary joinder. Reasoning that “[i]t is immaterial that there are no claims against UT, or that UT is named an involuntary plaintiff rather than an involuntary defendant,” the Court held that “Rule 19(a)(2) cannot be used to drag an unwilling UT into federal court” because “[t]he Eleventh Amendment serves to prevent ‘the indignity of subjecting a State to the coercive process of judicial tribunals’ against its will.” As for the exclusive licensee’s ability to proceed without UT, the Court explained that the district court abused its discretion by giving “controlling weight” to UT’s sovereign immunity, by failing to appreciate the alignment of interests between Gensetix and UT, and by ignoring that the license eliminated the risk of multiple suits because UT could not sue after Gensetix had done so.

Although both conclusions commanded a majority, they were different majorities. In a separate opinion, Judge Taranto agreed that UT could not be joined, but would also have held that Republic of Philippines v. Pimentel—a Supreme Court case requiring dismissal of claims where an absent [...]

PTAB May Reject Substitute Claims Under Any Basis of Patentability

by | Aug 5, 2020 | ,

The US Court of Appeals for the Federal Circuit considered for the first time whether a district court’s invalidity determination, when made final after all appeals are exhausted, divests the Patent Trial and Appeal Board (PTAB) of jurisdiction in a co-pending inter partes review (IPR) proceeding involving the same claims, and held that it does not. The Court also held that in an IPR proceeding, the PTAB is free to reject proposed substitute claims for failing to meet the subject matter eligibility requirements of § 101. Uniloc 2017 LLC v. Hulu, LLC, Case No. 19-1686 (Fed. Cir. July 22, 2020) (Wallach, J.) (Dyk, J., dissenting).

Hulu filed an IPR petition challenging claims of Uniloc’s patent directed to adjustable software licensing for digital products. After the PTAB instituted review, Uniloc filed a motion for substitute claims, conditional on whether the PTAB found the original claims unpatentable. Before the PTAB issued its final determination and before it ruled on the motion for substitute claims, a district court, in a related proceeding, held Uniloc’s asserted claims invalid as directed to patent-ineligible subject matter. Shortly thereafter, the PTAB issued a final written decision finding the challenged claims unpatentable over the prior art, and it found the substitute claims unpatentable under § 101. Uniloc appealed the PTAB’s use of § 101 to invalidate its substitute claims.

While Uniloc’s appeal of the Hulu IPR was pending, the Federal Circuit affirmed the district court’s invalidity finding as to the original claims. With respect to the Hulu appeal, the Federal Circuit ordered the parties to address whether the appeal was moot in view of the ultimate finality with respect to invalidity of the original claims, thereby divesting the PTAB of jurisdiction over the IPR.

The majority held that the finality of the district court’s invalidity finding did not necessarily divest the PTAB of authority to consider substitute claims. It determined that the mootness issue was waivable, and that Hulu had waived the argument because it failed to raise mootness during the pendency of the IPR at the time the district court issued its decision. Even if Hulu had not waived the argument, the majority found that the PTAB’s authority to consider substitute claims does not depend on any live dispute about the original claims, as long as the motion to amend in the IPR was timely filed.

As to the PTAB’s rejection of the claims under § 101, the majority held that although the PTAB is restrained in an IPR proceeding to invalidating a patent’s original claims only under the anticipation and obviousness grounds raised in the petition, the PTAB may use other invalidity tools as a “new ground of rejection” for substitute claims, including for lack of patentable subject matter under § 101. The majority also suggested that other grounds of patentability would be within the scope of the PTAB’s authority, including rejections under the various subsections of § 112. The majority was concerned that limiting the PTAB’s review might force it to issue substitute claims that fail to meet all the statutory [...]

Eighth Circuit Cools Off Antitrust Claims Based on Alleged Patent Fraud

by | Aug 5, 2020 |

The US Court of Appeals for the Eighth Circuit affirmed a grant of summary judgment dismissing antitrust and tortious interference claims based on fraudulent procurement of patents where the plaintiff failed to show a knowing and willful intent to deceive the US Patent and Trademark Office (PTO). Inline Packaging, LLC v. Graphic Packaging International, LLC, Case No. 18-3167 (8th Cir. June 18, 2020) (Smith, J.).

Inline Packaging and Graphic Packaging are manufacturers of susceptor packaging, a specialized food packaging used for microwaving frozen foods. Graphic developed the susceptor design in partnership with Nestlé in 2005. The packaging was redesigned from a prior patent obtained several years earlier. Although Graphic’s computer-aided design drafter was listed as the sole inventor of the redesigned packaging claimed in the asserted patent, Nestlé’s engineer provided feedback that was implemented into the design, including the addition and deletion of certain features of the packaging.

In 2014, Nestlé held an auction to select the next manufacturer of its susceptor packaging. Nestlé originally selected Inline as the supplier of its susceptor packaging, but later awarded 90% of the susceptor packaging business to Graphic after Graphic notified Nestlé that Inline would likely infringe on Graphic’s patents. In June 2015, Graphic initiated patent litigation against Inline. In July 2015, Inline brought an antitrust suit against Graphic alleging that Graphic monopolized the susceptor packaging market using anticompetitive practices in violation of federal and state antitrust laws. To support its antitrust claims, Inline alleged that Graphic fraudulently procured the asserted patents, made baseless litigation threats and engaged in predatory discount bundling through the use of multi-year supply agreements. At the time the lawsuit was initiated, Graphic was the dominant supplier of susceptor packaging, with an almost 95% share of the US market. The district court granted summary judgment in favor of Graphic, dismissing Inline’s claims. Inline appealed.

The Eighth Circuit reviews grants of summary judgment de novo to determine whether a genuine dispute of material fact exists and whether judgment is entitled as a matter of law. Here, all inferences were viewed in the light most favorable to Inline. Section 2 of the Sherman Act prohibits monopolizing, or attempting to monopolize, any part of the trade or commerce among the several states. To prove a violation of Section 2, a claimant must show that an entity possessed monopoly power in the relevant market and willfully acquired or maintained such monopoly power through anticompetitive conduct rather than as the result of fair competition (e.g., by means of a superior product or business acumen).

The Eighth Circuit first considered whether Graphic fraudulently procured the asserted patents. Patent fraud, also known as Walker Process fraud, can support a monopolization claim where the defendant procured the patent at issue by knowing and willful fraud on the PTO, or maintained and enforced the patent with knowledge of the fraudulent manner in which it was obtained. Knowing and willful fraud requires an intent to deceive or inequitable conduct. The Court reasoned that this standard requires clear and convincing [...]

The Naked Truth About Trademark Cancellation: Only Harm, No Proprietary Interest Required

by | Aug 5, 2020 |

The US Court of Appeals for the Federal Circuit determined that a contracting party that contractually abandoned any proprietary interest in a mark may still bring a cancellation action if it can “demonstrate a real interest in the proceeding and a reasonable belief of damage.” Australian Therapeutic Supplies Pty. Ltd. v. Naked TM, LLC, Case No. 19-1567 (Fed. Cir. July 24, 2020) (Reyna, J.) (Wallach, J., dissenting).

Australian sold condoms with the marks NAKED and NAKED CONDOMS, first in Australia in early 2000, then in the United States in 2003. Two years later, Australian learned that Naked TM’s predecessor had registered a trademark NAKED for condoms in September 2003. Australian and Naked TM communicated by email regarding use of the mark for a few years. Naked TM contended that the parties reached an agreement; Australian disagreed and said no final terms were agreed upon. Australian filed a petition to cancel the NAKED trademark registration. Ultimately, and after trial, the Trademark Trial and Appeal Board (TTAB) concluded that Australian lacked standing because it had reached an informal agreement that Naked TM reasonably believed was an abandonment of any right to contest Naked TM’s registration of NAKED. Thus, the TTAB found that Australian lacked a real interest in the proceeding because it lacked a proprietary interest in the challenged mark. Australian appealed.

The Federal Circuit reversed. First, the Court clarified that the proper inquiry was a matter of proving an element of the cause of action under 15 USC § 1064 rather than standing. The Court explained that, contrary to the TTAB’s conclusion, “[n]either § 1064 nor [its] precedent requires that a petitioner have a proprietary right in its own mark in order to demonstrate a cause of action before the Board.” Assuming without deciding that the TTAB correctly determined that Australian had contracted away its rights, the Court found that fact irrelevant. Ultimately, even though an agreement might be a bar to showing actual damages, a petitioner need only show a belief that it has been harmed to bring a petition under § 1064.

The Federal Circuit found that Australian had a reasonable belief in its own damage and a real interest in the proceedings based on a history of two prior applications to register the mark, both of which the US Patent and Trademark Office rejected on the basis that they would have created confusion with Naked TM’s mark. The Court rejected Naked TM’s argument that Australian’s abandonment of those applications demonstrated there was no harm, instead concluding that Australian’s abandonment of its applications did not create an abandonment of its rights in the unregistered mark. Moreover, as a prophylactic rationale, the Court explained that Australian’s sales of products that might be found to have infringed the challenged registration also create a real interest and reasonable belief in harm.

Judge Wallach dissented. Although he agreed that the TTAB erred by imposing a proprietary-interest requirement to bring suit under § 1064, he disagreed that Australian properly demonstrated an alternative, legitimate interest—i.e., a belief [...]

Without Personal Jurisdiction or Causal Relationship, Wheels Come Off Misappropriation Claim

by | Jul 30, 2020 |

Without addressing the merits of the claim, the US Court of Appeals for the Seventh Circuit affirmed a district court’s dismissal of a trade secret misappropriation action based on lack of personal jurisdiction, finding no causal relationship between the competitors’ dealings in Illinois and the asserted claims. J.S.T. Corporation v. Foxconn Interconnect Technology Ltd., et al., Case No.19-2465 (7th Cir. July 13, 2020) (Barrett, J.).

In 2005, General Motors (GM) retained Robert Bosch LLC to build a part for some of GM’s cars. To build the part, Bosch required a connector. Bosch turned to JST to design and build the part, which it did for years, becoming the sole supplier of the product to Bosch. After buying 15 million connectors, Bosch allegedly tricked JST into handing over its proprietary technical schematics and designs under the guise that GM required the materials and Bosch would keep them confidential. Instead, Bosch allegedly gave the materials to JST’s competitors, Foxconn and TEC. According to JST, Foxconn and TEC accepted the designs, used them to produce a knockoff connector and displaced JST.

JST filed a lawsuit against TEC and Foxconn affiliates in Illinois for trade secret misappropriation under the Illinois Trade Secrets Act and for unjust enrichment. TEC and Foxconn moved to dismiss the case for lack of personal jurisdiction because none of the defendants were headquartered in Illinois or had a primary place of business there. Further, none of the defendants manufactured or sold the connector in Illinois. JST alleged that TEC and Foxconn sold the connectors to Bosch in Texas and in China, where Bosch installed them into the parts it sold to GM. The only connection to Illinois was the fact that GM sells cars with those parts to dealers in Illinois. Foxconn and TEC argued that this connection was too attenuated to support personal jurisdiction. The district court agreed and dismissed the action. JST appealed.

On appeal, JST asserted that Foxconn and TEC were subject to personal jurisdiction in Illinois because the cars containing the knockoff parts were sold in the state. Relying on the Supreme Court of the United States’ decision in World-Wide Volkswagen, JST argued that personal jurisdiction may be appropriate over “a corporation that delivers its products into the stream of commerce with the expectation that they will be purchased by consumers in the forum State.” The Seventh Circuit observed that its circuit is among those that apply the stream of commerce theory in products liability cases. The Court explained that in the context of a product liability case, the defendant takes steps to reach consumers in a forum state, and the underlying litigation alleges the development of a product that harms consumers.

The Seventh Circuit noted the differences between products liability claims and those involving trade secret misappropriation. The latter is not intrinsically linked to interactions with a consumer and can occur long before an offending product ever reaches a consumer in the forum. Based on the complaint, the Court found that even if Foxconn and [...]

“Salacious” Content Doesn’t Bar Discovery in Copyright Infringement Suit

by | Jul 30, 2020 |

The US Court of Appeals for the District of Columbia Circuit preserved discovery options for copyright owners fighting online piracy when it reversed the district court’s refusal to allow a subpoena of an alleged online infringer’s internet service provider. The DC Circuit found that the district court abused its discretion by relying heavily on the copyright owner’s litigation history and the nature of its films rather than the relevant legal standards under the Federal Rules of Civil Procedure. Strike 3 Holdings, LLC v. John Doe, Subscriber Assigned IP Address 73.180.154.14 (DC Cir. July 14, 2020) (Rao, J.).

Strike 3 is a producer and online distributor of adult films. Like most of its industry peers, the company faces significant online piracy that is often facilitated by peer-to-peer file sharing. To combat this infringement, Strike 3 regularly files copyright infringement lawsuits against “John Doe” defendants based on the internet protocol (IP) address (and the associated physical address) tied to an online infringer’s illegal file sharing and downloads.

In 2018, Strike 3 filed a copyright infringement lawsuit against the IP address 73.180.154.14 John Doe subscriber located in the District of Columbia after the IP address was associated with 22 instances of infringement in the course of one year. To properly identify the defendant and serve the complaint, Strike 3 also filed a Rule 26(d)(1) motion seeking leave to subpoena Comcast, the subscriber’s internet service provider, for records identifying the John Doe IP address subscriber. But, in applying a multifactor balancing test adopted by the US Court of Appeals for the Second Circuit in Arista Records v. Doe, the district court denied Strike 3’s discovery motion on grounds that Strike 3’s need for the subpoenaed information was outweighed by defendant’s right to be anonymous, which the court found to be notably relevant given the risk of defendant misidentification and the “particularly prurient pornography” at issue.

On appeal, the DC Circuit acknowledged the district court’s broad discretion over the structure, timing and scope of discovery. In Strike 3’s case, however, the DC Circuit found that three aspects of the lower court’s analysis were an abuse of this broad discretion.

First, it was improper and “not supported by the relevant legal standards” for the district court to treat the pornographic content of Strike 3’s copyrighted works as relevant to its entitlement to early discovery. None of the supporting case law suggests that a potentially non-infringing defendant’s privacy interests vary depending on the content of the copyrighted work at issue. The Court warned that a plaintiff’s ability to defend its copyrights cannot turn on a court’s subjective view of the copyrighted material, and held that the content of a copyrighted work is per se irrelevant to a Rule 26(d)(1) motion seeking discovery to identify an anonymous infringer.

The district court’s second abuse of discretion was in its conclusion that, even if the discovery request was granted, Strike 3 could not “identify a copyright infringer who can be sued” for purposes of stating a plausible claim against the [...]

Unnamed Respondent Has Standing to Seek Rescission of ITC General Exclusion Order

by | Jul 30, 2020 |

The US Court of Appeals for the Federal Circuit affirmed a US International Trade Commission (ITC) decision denying a petition for rescission of a general exclusion order (GEO) prohibiting importation of products accused of patent infringement, because a post-investigation invalidity attack is not a changed condition warranting rescission. Mayborn Grp., Ltd. v. Int’l Trade Comm’n, Case No. 19-2077 (Fed. Cir. July 16, 2020) (Lourie, J.).

Several parties filed a complaint at the ITC against several respondents, not including Mayborn Group, Ltd., and Mayborn USA, Inc. The complaint alleged infringement of a patent disclosing a self-anchoring beverage container that prevents spills. The complainants sought a GEO barring importation of infringing goods by any party, including unnamed respondents such as Mayborn. In contrast to GEOs, limited exclusion orders only prohibit infringing goods imported by named respondents in an investigation. The ITC instituted an investigation, and the administrative law judge determined that two respondents were in default and liable for unfair acts (patent infringement) in connection with importation. The defaulting respondents did not raise any invalidity challenge during the investigation. On the administrative law judge’s recommendation, the ITC issued a GEO.

Following issuance of the GEO, Mayborn continued to import potentially infringing products. The complainants notified Mayborn that they were working with US Customs and Border Protection (CBP) to enforce the GEO against Mayborn’s importations. In response, Mayborn petitioned the ITC to rescind the GEO pursuant to its power to rescind or modify an order if there is a change in the conditions that led to the GEO. Mayborn argued that the “changed condition” requirement was satisfied because it contends the asserted claims are invalid.. The ITC denied Mayborn’s petition, holding that a petitioner’s asserted discovery of invalidating prior art after the issuance of a GEO was not a changed condition. Mayborn appealed, arguing that the ITC erred in rejecting its request for rescission. The ITC alleged that Mayborn lacked standing to appeal because Mayborn’s alleged injury stemmed from the complainants’ threat to enforce the GEO rather than any act by the ITC.

The Federal Circuit affirmed, finding that Mayborn’s post-investigation invalidity challenge was not a basis for rescission of the GEO. The Court first addressed the ITC’s standing argument, and determined that Mayborn had standing because it was injured by the GEO and the GEO was enforced by the ITC. The ITC or CBP could act to enforce the GEO at any time. Mayborn had also lost sales and incurred other harm stemming from the complainants’ threats to assert the GEO, including reputational injury, market share loss and damaged business relationships. Standing did not require the ITC to have already barred importation of Mayborn’s products.

After finding that Mayborn had standing, the Federal Circuit determined that Mayborn’s invalidity challenge was not a permissible basis to seek rescission of the GEO for two reasons. First, although patent invalidity is an affirmative defense to patent infringement, the ITC is constrained to adjudicating patent validity only when a respondent raises an invalidity defense during an [...]

Independently Performed, Publicly Disclosed Prior Work Can Lead to Joint Inventorship

by | Jul 23, 2020 |

Addressing an inventorship decision that added two co-inventors to patents covering cancer treatments, the US Court of Appeals for the Federal Circuit agreed that the co-inventors’ work constituted joint inventorship even though it was performed independently and publicly disclosed prior to conception of the claimed invention. Dana-Farber Cancer Institute v. Ono Pharma. Co., Ltd., Case No. 19-2050 (Fed. Cir. July 14, 2020) (Lourie, J.).

In 2015, Dana-Farber filed an inventorship correction claim seeking to add two of its researchers as inventors to six patents covering cancer treatments that named inventors who had assigned the patents to Ono Pharmaceutical. After an eight-day bench trial, the district court judge issued a 111-page decision agreeing that Dana-Farber’s researchers were joint inventors for all six patents. Ono appealed.

Ono first argued that, as a matter of law, the contributions from Dana-Farber’s researchers were too far removed from the claimed invention because their contributions had been independently performed and publicly disclosed prior to conception, and thus constituted prior art to the patents. The Federal Circuit acknowledged that simply informing another inventor about the state of the prior art does not make one a joint inventor. However, the Court contrasted that situation with a genuine contribution by a participant in a collaborative enterprise that lasted over a year, where the contribution happened to be published shortly before conception. The Court stated that such a situation may be sufficient to lead to joint inventorship.

Ono also contested the district court’s factual determination that Dana-Farber’s researchers contributed to the invention as claimed. Specifically, Ono argued that the contributions from Dana-Farber’s researchers did not relate to the claimed subject matter of an antibody for a particular receptor. Dana-Farber responded that, as found by the district court, all six patents had the same core invention of blocking a particular ligand-receptor interaction and thus the identification of the relevant ligand by Dana-Farber’s researchers was properly considered part of the conception of all claims. The Federal Circuit agreed and affirmed the district court.
