Federal Circuit Appeals

Entities with patent-related relationships with state universities scored a victory under the rarely implicated (at least for patent practitioners) doctrine of sovereign immunity.  For patent holders, sovereign immunity comes into play when a state actor, for example a state university, enters contracts related to patents, such as in Gensetix v. Baylor College of Medicine. 

Last week a Federal Circuit panel in Uniloc 2017 LLC v. Hulu, LLC issued an important decision regarding inter partes review (IPR) before the Patent Trial and Appeal Board on two questions concerning contingent motions to amend—(i) whether the Office has statutory authority to review the patentability of substitute claims after a final federal-court judgement of invalidity of those claims and, if yes, (ii) whether that review of patentability may include analyzing the substitute claims for patent eligibility under 35 U.S.C. § 101. 

Recently, in Packet Intelligence LLC v. NetScout Sys., Inc., No 19-2041 (July 14, 2020), the Court of Appeals for the Federal Circuit reversed a jury verdict of $3.5 million in pre-suit damages and vacated the trial court’s enhancement of that award because licensees of the asserted patents failed to properly mark allegedly patent practicing products.

Recent oral arguments at the Fed Circuit suggest that the U.S. may be taking steps which would enhance its attractiveness for SEP patent holders looking to resolve licensing disputes.  The Federal Circuit heard oral argument on Monday, July 6th, in Godo Kaisha IP Bridge I v. TCL Commc’n Tech. Holdings Ltd., No. 19-2215, that may pave an easier path for owners of standard essential patents (“SEPs”) to prove literal infringement of products that comply with that standard. 

On May 8, 2020, the Court of Appeals for the Federal Circuit affirmed the District of Delaware’s application of the disclosure-dedication doctrine in granting a motion for judgment on the pleadings in Eagle Pharmaceuticals Inc. v. Slayback Pharma LLC, No. 19-1924. 

Last week, the Federal Circuit, in a precedential decision, reinforced that an accused infringer can be a “prevailing party” for the purposes of seeking attorneys’ fees under 35 U.S.C. § 285 when it successfully invalidates the asserted patent at the Patent Trial and Appeal Board (“PTAB”). 

On Wednesday, the Federal Circuit held that while assignor estoppel is applicable in district court proceedings, petitions for inter partes review continue to not be subject to the equitable remedy.  Assignor estoppel is an equitable doctrine based on the principle of fair dealing that prevents a party who divests a patent from later challenging the validity of that patent.

On Thursday, the Federal Circuit ruled that the Patent Trial and Appeal Board (“PTAB”) must give the parties proper notice if considering a sua sponte theory of unpatentability in relation to a motion to amend.

The Court of Appeals for the Federal Circuit ruled in February that the Patent Trial and Appeal Board (PTAB) cannot cancel claims for indefiniteness in an inter partes review (IPR) proceeding. The case is Samsung Electronics America, Inc., v. Prisua Engineering Corp., case number 19-1169, in the U.S. Court of Appeals for the Federal Circuit.

The Federal Circuit’s decision in ATI Technologies ULC v. Iancu (April 11, 2019) highlights the proper standard to use in evaluating whether a claimed invention was reduced to practice before the effective date of a prior art reference.

In the continuing Amgen v. Sanofi saga, Amgen has asked SCOTUS to take up the issue of written description, which is currently established by showing “whether the disclosure…reasonably conveys…that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010)(en banc)(emphasis added).

In Ethicon Endo-Surgery, Inc. v. Covidien LP, a 2-1 panel split of the Federal Circuit held that neither the American Invents Act (“AIA”) nor the Constitution precludes the same panel of the Patent Trial & Appeal Board (“PTAB” or “Board”) from both deciding whether to institute an inter partes review (“IPR”) of a challenged U.S. Patent and making the final patentability determination in that IPR.
