Federal Circuit Erases Juno’s $1 Billion Judgment by Invalidating Patent for Inadequate Written Description

By Anne Bolamperti and David G. Barker The Federal Circuit invalidated Juno Therapeutics, Inc.’s T cell therapy patent for cancer treatment and erased a billion dollar judgment in Juno’s favor.

Juno’s U.S. Patent No. 7,446,190 (the “’190 patent”) relates to a nucleic acid polymer encoding a three-part chimeric antigen receptor (“CAR”) for a T cell. The first two portions of the CAR allow T cells to both kill target cells and divide into more T cells. The third portion   Read More »

Supreme Court Determines New Limitations to Assignor Estoppel Doctrine

By Marsha Cotton and David G. Barker The Supreme Court upheld assignor estoppel in Minerva Surgical, Inc. v. Hologic, Inc., et al. but held that the Federal Circuit “failed to recognize the doctrine’s proper limits.” In doing so, the Court imposed new limitations on when the equitable doctrine applies in a patent case.

Previously, courts applied the rule without looking to the individual facts and circumstances in each case. But the Court held   Read More »

Supreme Court Holds that PTAB Judges Are Unconstitutionally Appointed

By Daniel M. Staren and David G. Barker The Supreme Court held this week that the United States Patent and Trademark Office’s (“USPTO”) appointment of Patent Trial and Appeal Board (“PTAB”) judges cannot be constitutionally enforced because the USPTO director does not have authority to review final PTAB decisions. Smith & Nephew, Inc. and ArthroCare Corp. petitioned for inter partes review in the USPTO against Arthrex, Inc.’s patent on a surgical device. A PTAB panel consisting of three administrative patent judges (“APJs”) concluded that Arthrex’s patent was invalid.

By Zachary Schroeder and Jacob C. Jones On June 1, 2021, the U.S. Supreme Court granted certiorari in Unicolors, Inc. v. H&M Hennes & Mauritz, LP.  The Court agreed to resolve whether 17 U.S.C. § 411(b) requires a district court to refer a matter to the Copyright Office where there is a claim the copyright registration holder made a knowing misrepresentation to the Copyright office in obtaining the registration, but there is no indicia of fraud or material error by the copyright holder.  H&M has asked the Court to interpret the statute as requiring referral merely upon a showing of   Read More »

Supreme Court Grants Certiorari to Resolve Long-Running Debate on Assignor Estoppel

By: David G. Barker and Emily R. Parker Last Friday, the U.S. Supreme Court granted certiorari in Minerva Surgical v. Hologic, thereby agreeing to resolve a long-running debate on patent law’s doctrine of assignor estoppel. Minerva Surgical has asked the Court to abolish the doctrine, which bars inventors who sell their patent rights from challenging the patent’s validity in district court. The inventor in this case, Csaba Truckai, co-founded a company called NovaCept and developed two patents for endometrial ablation, a surgical process used to treat menstrual bleeding. NovaCept sold its patents to Cytyc Corp., which was acquired by Hologic.   Read More »
