Federal Circuit Tosses Shaw: IPR Estoppel Applies to All Grounds That Reasonably Could Have Been Raised

by Paul Devinsky | Feb 17, 2022 | Patents

March 2022 Update: The Federal Circuit has issued an errata to this decision. Read about it here.

Addressing inter partes review (IPR) estoppel after the Supreme Court of the United States’ 2018 decision in SAS Institute, Inc. v. Iancu, the US Court of Appeals for the Federal Circuit overruled its decision in Shaw Industries Group v. Automated Creel Systems, stating that the only plausible reading of 35 U.S.C. § 315(e)(2) estops a party from raising all claims and grounds that reasonably could have been included in the party’s petition for IPR. The Court also rejected the district court’s two-tier damages model as contrary to customary patent damages calculations. California Institute of Technology v. Broadcom Limited, Case Nos. 20-2222; 21-1527 (Fed. Cir. Feb. 4, 2022) (Lourie, Linn, Dyk, JJ.) (Dyk, J., dissenting in part).

Background

California Institute of Technology (Caltech) filed suit against Broadcom and Apple, alleging patent infringement directed to the generation and repetition of information in a wireless data transmission system. Wireless transmission systems generally use data repetition so that the transmitted information may be decoded even when data loss occurs. The patented circuitry discloses a form of irregular data repetition in which portions of the information bits may be repeated a varying number of times.

Apple filed multiple IPR petitions challenging the validity of the claims at issue. The Patent Trial & Appeal Board (Board) concluded in all cases that Apple failed to show that the challenged claims were unpatentable as obvious. At the district court, Apple and Broadcom raised new arguments of obviousness not asserted in the IPR proceedings. The district court granted Caltech’s motion for summary judgment of no invalidity, precluding Apple and Broadcom from raising arguments at trial that they reasonably could have raised in their IPR petitions.

At trial, the district court instructed the jury that “repeat” means “generation of additional bits, where generation can include, for example, duplication or reuse of bits.” Apple and Broadcom argued that the Broadcom chips (which were integrated into Apple devices) did not infringe the asserted claims because they did not repeat information at all. With respect to one of the asserted patents, the district court did not provide a jury instruction relating to its construction that the claim language “information bits appear in a variable number of subsets” requires irregular information bit repetition. The jury found infringement of all asserted claims. Apple and Broadcom filed post-trial motions for judgment as a matter of law (JMOL) and a new trial, both of which the district court denied.

The district court adopted Caltech’s proposed two-tier damages theory, explaining that Broadcom and Apple’s products were different and therefore possessed different values simply because they were “different companies at different levels in the supply chain.” The district court ultimately entered judgment against Broadcom for $288 million and against Apple for $885 million. Broadcom and Apple appealed.

The Appeal

Broadcom and Apple argued that the district court’s construction of “repeat” was inconsistent with the claim language and specification. The Federal Circuit [...]

Without More, Mere Automation is Abstract—Not Construing Interchangeable Terms Doesn’t Give Them the Cold Shoulder

by McDermott Will & Emery | Aug 19, 2021 | Patents

In the latest development relating to patent eligibility of content-based identifier patents, the US Court of Appeals for the Federal Circuit affirmed decisions finding patent claims ineligible under 35 U.S.C. § 101. PersonalWeb Techs. LLC v. Google LLC, YouTube, LLC, Case No. 20-1543 (Fed. Cir. Aug. 12, 2021) (Prost, J.) (consolidating PersonalWeb Techs. LLC v. Facebook, Inc., Case No. 20-1553, and PersonalWeb Techs. LLC, Level 3 Commc’ns. LLC v. EMC Corp., VMWare, Inc., Case No. 20-1554).

PersonalWeb sued technology companies in the Eastern District of Texas in 2011 over three of its patents. The patents were directed to data-processing systems that assign each data item a substantially unique content-based identifier, generated by hash algorithm, which changes when the content changes and is used to perform data-management functions. Several defendants successfully motioned for transfer to the Northern District of California, where their companies were headquartered and/or their employees responsible for the development of the accused products were based. After claim construction in Texas, the cases were transferred and stayed pending several inter partes reviews before the US Patent Trial & Appeal Board (Board). Previous decisions before the Federal Circuit affirmed the Board’s findings that using hash-based identifiers for data management was disclosed in the prior art, that content-based identifiers in performing file-management functions, such as backing up files, were also known and other independently unpatentable aspects were recited in the claims. After the stay was lifted, the California court granted the defendants’ motion for judgment on the pleadings that the remaining asserted claims were patent ineligible under 35 U.S.C. § 101. PersonalWeb appealed.

To assess patent eligibility, the Federal Circuit applied the two-step Mayo/Alice framework. Under step one (determining whether the claims at issue are directed to a patent-ineligible concept, such as an abstract idea), the Court considered the focus of the claimed advance over the prior art and found that the claims were directed to an abstract idea. PersonalWeb contended that its claims were directed to “a substantially unique, algorithm-derived, content-based identifier for all data items in a networked computer, which allows a computer within a network containing diverse computing and storage systems to locate and distribute data without knowing either the file system of any device within the network or the conventional name of any data item.” However, the Court adopted the district court’s view, which was that the patents were directed to “(1) using a content-based identifier generated from a ‘hash or message digest function,’ (2) comparing that content-based identifier against something else, [that is,] another content-based identifier or a request for data; and (3) providing access to, denying access to, or deleting data.” Given the focus in Mayo/Alice step one of “whether the claims of the asserted patents fall within the excluded category of abstract ideas,” and citing to parallel examples from precedent cases, the Court concluded that the claims were directed to the use of an algorithm-generated content-based identifier to perform the claimed data-management functions, which include controlling access to data items, retrieving and delivering copies [...]

Attempts to Appeal Institution Decision Is SIPCOed

by McDermott Will & Emery | Feb 18, 2021 | America Invents Act, Patents

Reinforcing the impact of the Supreme Court of the United States’ 2019 decision in Thryv v. Click-to-Call, the US Court of Appeals for the Federal Circuit reiterated that the Patent Trial and Appeal Board’s threshold determination as to whether it will institute a proceeding under the America Invents Act (AIA), in this instance a Covered Business Method (CBM) review, is not appealable because it is closely tied to the institution decision. cxLoyalty, Inc. v. Maritz Holdings Inc., Case Nos. 20-1307, -1309 (Fed. Cir. Feb. 8, 2021) (Prost, C.J.)

cxLoyalty petitioned for CBM review of a patent owned by Maritz. The patent relates to a system and method for permitting a loyalty program customer to redeem loyalty points for rewards offered by vendors without human intervention. A participant (i.e., a customer) uses a graphical user interface (GUI) to communicate with a web-based vendor system (e.g., an airline reservation system). An application programming interface (API) facilitates information transfer between the GUI and the vendor system.

The Board instituted CBM review and concluded that the original claims in the patent were ineligible for patenting under 35 USC § 101, but that the proposed substitute claims were patent eligible. The Board found the original and substitute claims amounted “to a fundamental economic practice long prevalent in commerce” and therefore were directed to abstract ideas. However, the Board found that, unlike the original claims, the substitute claims contained an inventive concept. cxLoyalty appealed the Board’s ruling as to the substitute claims. Maritz cross-appealed the Board’s determination that the patent was eligible for CBM review and the Board’s ruling as to the original claims.

The Federal Circuit quickly disposed of Maritz’s challenge to the CBM-eligibility of the patent, citing to its 2020 SIPCO v. Emerson decision. In SIPCO, the Court held that Thryv made clear that the Board’s threshold determination as to whether a patent qualifies for CBM review is a non-appealable decision. Whether CBM review is an available mechanism is conditioned on whether the patent qualifies, since patents that are directed to “technological inventions” are excluded from CBM review. Because the determination of whether a patent qualifies for CBM review is inextricably tied to the decision to institute, it is not appealable. SIPCO was decided after briefing but before oral argument of this case. Indeed, Maritz’s counsel acknowledged during oral argument that SIPCO foreclosed Maritz’s CBM eligibility challenge.

As to the merits, the Federal Circuit agreed with the Board that both the original and substitute claims were directed to patent-ineligible subject matter under § 101. Maritz argued that the claim features of permitting a participant to redeem points for rewards “without knowing that the actual transaction is a currency transaction at less than the perceived price” saved the claims from being merely abstract ideas. The Court disagreed. After applying the Alice/Mayo two-step analysis, the Court found that 1) the claims were directed to abstract ideas, and 2) the claims merely recited generic and conventional computer components or functionality for carrying out the abstract [...]

Printed Matter Is Patentable If It’s Functional, Not Just Communicative

by McDermott Will & Emery | Nov 19, 2020 | Patents

In a tour de force of issues related to the printed matter doctrine, the US Court of Appeals for the Federal Circuit reversed various rulings that the patents-in-suit were not infringed, not willfully infringed and invalid as directed to printed matter. Instead, the Court held that there was substantial evidence in the record to support a jury finding of infringement and willfulness, and that the asserted claims were not directed solely to printed matter and thus were patent eligible under 35 USC § 101 (thereby raising a genuine dispute of material fact that precludes summary judgment as to anticipation). C R Bard Inc. v. AngioDynamics, Inc., Case Nos. 19-1756, -1934 (Fed. Cir. Nov. 10, 2020) (Reyna, J.)

This dispute began when Bard sued AngioDynamics for infringing three patents directed to identifying a vascular access port that is suitable for power injection, which is a medical procedure requiring injecting fluids into a patient at a high pressure and flow rate. Generally, the identification was accomplished by certain markings on the vascular access port that can be detected during an x-ray scan.

Prior to trial, AngioDynamics moved for summary judgment on patent eligibility, novelty and enablement. This summary judgment motion was initially denied, but the district court sought a report and recommendation prior to trial regarding whether certain limitations relating to radiographic marker images were entitled to patentable weight under the printed matter doctrine. The magistrate judge concluded that the limitations were not entitled to patentable weight, and the district court adopted the recommendation. At trial and at the end of Bard’s case-in-chief, AngioDynamics moved for judgment as a matter of law (JMOL) on non-infringement and no willfulness. Ultimately, the district court terminated the trial and granted AngioDynamics’ JMOL motion for non-infringement and no willfulness. The district court further held that the claims were invalid because they were directed to printed matter and were not inventive. Bard appealed, challenging each of the district court’s findings.

In reversing the summary judgment of no infringement, the Federal Circuit explained that Bard’s expert’s reliance on an incorrect understanding of the district court’s claim construction was alone insufficient to grant judgment as a matter of law. Instead, the expert’s misunderstanding went to credibility, and the Court found the record reflected that the expert properly testified that the various claim elements were met under the proper claim constructions. The Court further explained that Bard did not have an affirmative duty to test AngioDynamics products, but rather was entitled to rely on AngioDynamics’ representations to the US Food and Drug Administration and to its customers. With regard to induced infringement, the Court explained that if an alleged infringer instructs its users to use the product in an infringing way, there is sufficient evidence for a jury to find infringement. Because the district count found no inducement based on its erroneous summary judgment of no infringement, that ruling was similarly reversed.

The Federal Circuit also reversed the district court on its summary judgment of no willfulness, concluding that Bard [...]

Federal Circuit Sinks Another Attempt to Use PTO Guidance

by Paul Devinsky | May 7, 2020 | Patents

The US Court of Appeals for the Federal Circuit found claims directed to methods of fishing to be patent ineligible, affirming a Patent Trial and Appeal Board (PTAB) decision that the claims were directed to the abstract idea of selecting a fishing hook based on observed water conditions. In re: Christopher John Rudy, Case No. 19-2301 (Fed. Cir. Apr. 24, 2020) (Prost, CJ).
