The Federal Circuit recently reversed a decision of the Patent Trial and Appeal Board (Board) finding claims of a patent owned by PersonalWeb Technologies, LLC to be invalid.  Apple, Inc. (Apple) petitioned for inter partes review (IPR), and the Board found certain claims of the patent to be invalid as obvious in light of two references.  The Federal Circuit reversed, holding the Board provided insufficient evidence to support a finding of inherency.  Pers. Web Techs., LLC v. Apple, Inc., No. 2018-1599, 2019 U.S. App. LEXIS 6919 (Fed. Cir. Mar. 8, 2019) (Before Moore, Taranto, and Chen, Circuit Judges) (Opinion for the Court, Chen, Circuit Judge).

Since the America Invents Act ushered in a series of sweeping changes to the U.S. patent system in 2011, IP stakeholders have been grappling with Inter Partes Review proceedings (IPRs) before the Patent Trial and Appeal Board (PTAB). More than 8,000 IPR petitions have been filed since 2012. IPRs differ from court proceedings in many ways, including more restricted discovery, tighter deadlines, and particular rules and procedures for the submission of arguments and evidence. Despite these differences, the substantive law underlying the patent challenges is the same for IPRs and court proceedings. In an IPR, a Petitioner is allowed to challenge a patent’s validity under the doctrines of anticipation or obviousness. These same challenges are available in court, and the substantive law for anticipation and obviousness is theoretically supposed to be the same for IPRs or for court proceedings. Given that the substantive doctrines of anticipation and obviousness have existed and have been refined for more than a century, and that these doctrines are the same for PTAB and federal court proceedings, practitioners have tended to focus more on the doctrines, rules and procedures specific to IPRs when publishing on IPR practice. An in-depth study of obviousness in IPRs, however, reveals significant differences in the way the PTAB analyzes obviousness as compared to the courts and issues where the PTAB’s approach has changed over time. Over 90% of final written decisions in IPRs in the last three years have included obviousness grounds (as compared to less than 30% for anticipation). The doctrine of obviousness includes a multi-factor test, each factor including numerous sub-doctrines that can impact the analysis. Understanding precisely how the PTAB is analyzing and treating obviousness can improve a litigant’s chances of success in an IPR, whether as a patent owner or a patent challenger.

Is an invention arrived at by multiple inventors within a short space of time necessarily obvious? If not, how far may the evidence of simultaneous or contemporaneous invention go toward proving obviousness? Simultaneous invention is not common, but evidence of such invention, when present, can be important for reaching a conclusion of obviousness. Simultaneous invention can sometimes occur in the aftermath of the introduction of an enabling or foundational technology, when multiple groups working independently solve a problem, which, but for the foundational technology, would not have been possible. A recent example of this scenario can be found in the litigation related to the CRISPR-Cas9 technology, which culminated in a decision by the Federal Circuit in September 2018. University of California v. Broad Institute, Inc. (Fed. Cir. 2018) (UC v. Broad).

The Federal Circuit on February 1 affirmed the Patent Trial and Appeal Board’s final written decision in an inter partes review concluding that the claims of a patent directed to a composition for treating epilepsy are not unpatentable. The Federal Circuit first visited the issue of whether three petitioners—Mylan Pharmaceuticals, Breckenridge Pharmaceuticals, and Alembic Pharmaceuticals, all of whom were sued for infringement of the patent more than one year prior to the institution of the IPR, and all of whom were joined in the IPR under 35 U.S.C. § 315(c)—had standing to appeal the Board’s final decision. The Court held that the petitioners had a statutory right, under 35 U.S.C. § 319 to appeal.

Today marks the return of our Other Barks & Bites feature, which will profile a collection of news headlines from around the IP world and across practice areas every Friday. This week, the patent spat between Apple and Qualcomm heats up at the PTAB; China’s intellectual property court at Beijing shows signs of heightened requirements in trademark appeals for foreign entities; and the European Union delays debate on copyright reforms that would affect major tech firms that aggregate news and videos online.

On behalf of nonprofit, U.S. Inventor, Inc., and over a dozen other amici, Flachsbart & Greenspoon, LLC has submitted a Brief of Amici Curiae urging the Supreme Court to grant certiorari from the Federal Circuit’s notoriously error-ridden decision in the waterskiing case: Zup, LLC v. Nash Manufacturing, Inc. Reviewing this decision will be an excellent way to get obviousness doctrine back on track.

In that 2-1 decision (with Judge Newman dissenting), the Federal Circuit held that even “considerable” or “strong” objective evidence of nonobviousness will sometimes not save a patent from an obviousness ruling. That ruling is wrong. It is also out of touch with Supreme Court doctrine.

In AC Techs., S.A. v. Amazon.com, Inc. the Federal Circuit found the PTAB did not exceed its statutory authority by addressing a non-instituted ground on reconsideration; in fact, it would have violated the statutory scheme for the PTAB not to consider the previously non-instituted ground… The claims at issue related to data access and management, namely, storing copies of data across a network to improve data integrity and reduce network lag. Amazon and Blizzard challenged the ’680 patent based on a single prior art reference. They presented three grounds in their petition, all centered on the construction of the term “computer unit.”

On January 10, the Federal Circuit issued an opinion affirming a decision of the Patent Trial and Appeal Board (PTAB) invalidating several claims of U.S. Patent No. 6,597,812 (the ‘812 patent) as obvious. Realtime Data, LLC v. Iancu, No. 2018-1154 (Fed Cir. Jan. 10, 2019) (Before Dyk, Taranto, and Stoll, Circuit Judges) (Opinion for the court, Stoll, Circuit Judge).

Hewlett Packard Enterprise Co., HP Enterprise Services, LLC, and Teradata Operations, Inc. (collectively, HP) sought inter partes review (IPR) of U.S. Patent No. 6,597,812, alleging that the claims were obvious under 35 U.S.C. §103(a) over U.S. Patent No. 4, 929, 946 (O’Brien) and further, in view of a data compression textbook by Mark Nelson (Nelson). After instituting review, the PTAB found the challenged claims obvious over the prior art. Realtime Data appealed on two grounds: (1) that the PTAB erred in determining that a person of ordinary skill would have been motivated to combine the teachings of O’Brien and Nelson, and (2) that the PTAB erred by failing to properly construe the term “maintaining the dictionary”.

On appeal, the Federal Circuit accepted HP’s primary argument that all of the challenged claims were disclosed in O’Brien, with Nelson used only to demonstrate that the term “dictionary encoder” used in the ‘812 patent was actually what was disclosed in O’Brien. HP thus relied on Nelson merely to explain that O’Brien’s algorithm was a dictionary algorithm, which Realtime conceded. Because the PTAB did not rely on Nelson for the disclosure of any particular element or teaching and instead relied on O’Brien alone to supply the elements and teachings, there was no obligation to make any finding regarding a motivation to combine O’Brien and Nelson. Therefore, the PTAB “did not err when it concluded that claim 1 was invalid under § 103 based on O’Brien alone,” Judge Stoll wrote.

Federal Circuit issued a Rule 36 summary judgment in Chart Trading Development, LLC v. Interactive Brokers LLC, affirming the invalidation of patent claims owned by Chart Trading in covered business method (CBM) proceedings instituted at the Patent Trial and Appeal Board (PTAB). In issuing the summary affirmance of the PTAB, the Federal Circuit panel of Circuit Judges Pauline Newman, S. Jay Plager and Kimberly Moore declined the opportunity to comment on Chart Trading’s arguments on the PTAB’s alleged due process violations by changing the construction of a key term in its final written decision… If the government can award a franchise and that franchise can be taken away in a manner that violates the APA, what is the point in seeking the government franchise in the first place? If the Court charged with making sure the agency that strips government franchises is following the rules is going to decide cases of such importance with only one word — Affirmed — one has to question whether a government franchise is at all a worthwhile pursuit.

The Federal Circuit panel of Circuit Judges Timothy Dyk, Evan Wallach and Richard Taranto determined that the PTAB’s decision to uphold patent claims challenged by WhatsApp as nonobvious wasn’t supported by substantial evidence and that the PTAB didn’t properly consider expert testimony provided by WhatsApp… Here the prior art references that supplied all of the claim limitations and the Federal Circuit found that testimony from expert witnesses on both sides supported the idea that video and multimedia content was better at conveying more powerful messages than text or still photos.

A jury in the United Stated Federal District Court for the District of Delaware recently delivered a verdict awarding nearly $24 million dollars in reasonable royalty damages to plaintiffs Bio-Rad Laboratories and the University of Chicago. Along with finding that defendant 10x Genomics had infringed upon patents covering genetic analysis technologies, the jury also found that 10x Genomics’ infringement was willful and found it “highly unprobable” (i.e., the words of the jury verdict form) that the asserted patent claims were valid.

On Friday, November 9th, the Court of Appeals for the Federal Circuit issued a nonprecedential decision in NuVasive, Inc. v. Iancu, which vacated certain findings of the Patent Trial and Appeal Board (PTAB) in an inter partes reexamination proceeding involving a NuVasive patent covering a system and methods for minimally invasive surgical procedures. The Federal Circuit panel of Circuit Judges Pauline Newman, Raymond Chen and Todd Hughes determined that on the issue of secondary considerations the PTAB erred in finding no nexus between NuVasive’s claimed method and the surgical procedure actually commercialized by NuVasive. The panel also held that further fact-finding was required in order to determine whether an asserted prior art publication teaches a certain nerve-monitoring technique necessary to support the Board’s determination of obviousness. Therefore, the decision of the PTAB was vacated and the case remanded for further proceedings consistent with the Court’s opinion.

Today the flash of creative genius test has reared its ugly head once more, this time as a consideration under a patent eligibility inquiry and 35 U.S.C. 101 instead of under an obviousness inquiry and 35 U.S.C. 103. Today, thanks to the Supreme Court’s unintelligible Alice/Mayo framework, one must ask whether significantly more has been added to a patent claim such that the claim does not merely claim an abstract idea, law of nature or natural phenomenon. This final step in the Alice/Mayotest is referred to by the Courts as the hunt for the inventive concept. It is difficult not to notice the similarity between this hunt for the inventive concept that takes place when reviewing a claim under 101 and the supposedly defunct flash of creative genius test Congress attempted to write out of patent law in 1952.

The Patent Trial and Appeal Board issued a decision denying the institution of an inter partes review (IPR) proceeding petitioned by home appliance developer SharkNinja. The decision leaves in place all claims of a patent asserted against SharkNinja in U.S. district court through a patent infringement case filed by appliance hose manufacturer Flexible Technologies. In denying SharkNinja’s petition for IPR, the PTAB panel of Administrative Patent Judges (APJs) found that implementing the hose found in Rohn to be a stretch hose as taught by Martin would render Rohn’s hose inoperable for its intended purpose… As for the Nagayoshi prior art reference, the PTAB sided with Flexible Technologies in finding that SharkNinja’s asserted combination is difficult to distinguish from a hindsight analysis…

Since Merck & Co. v. Teva Pharmaceuticals, blocking patent arguments have arisen in the Federal Circuit primarily in the pharmaceutical patent context, and until now have largely been limited to undermining evidence of commercial success. But just like gremlins fed after midnight, this doctrine inevitably spawned unwanted offspring that are now wreaking havoc… Assuming that no one would ever develop a product that might infringe a patent is inconsistent with numerous Federal Circuit realities. It’s right up there with the Tooth Fairy (sorry, kids).
