Wilson Sonsini Successfully Represents Impossible Foods in First-of-Its-Kind FoodTech Patent Suit
Wilson Sonsini served as lead counsel for Impossible Foods in a patent infringement litigation alleging infringement of seven Impossible Foods patents covering manufacturing processes, ingredients, and finished products relating to plant-based food containing heme and Impossible’s innovative transgenic yeast used to manufacture that heme. Our team successfully represented Impossible Foods in defense of six inter partes review petitions before the Patent Trial and Appeal Board in 2022 and 2023. Wilson Sonsini defeated the defendant’s motion to dismiss and motion to stay the District Court litigation. The matter was closely watched as the first patent infringement case in the burgeoning foodtech industry. With trial approaching, the parties resolved the matter and released a joint statement that said: “This resolution affirms Impossible Foods’ category leadership and the strength of its product portfolio related to heme.”

En Banc Federal Circuit Paves the Way for Easier Claim Amendments in Inter Partes Review Before the PTAB
On October 4, 2017, the U.S. Court of Appeals for the Federal Circuit issued an en banc decision in Aqua Products, Inc., v. Matal, finding that the petitioner has the burden of proving the unpatentability of claims—even amended claims—entered in an inter partes review (IPR). This decision overrules earlier Federal Circuit decisions finding that the burden rested on the patent owner to prove patentability of amended claims and will force immediate changes to amendment practice in trials at the Patent Trial and Appeal Board (PTAB).

Federal Circuit Ruling in Dell v. Acceleron Limits New Late-Stage Grounds of Challenge in America Invents Act Trials
On March 15, 2016, the U.S. Court of Appeals for the Federal Circuit held that the Administrative Procedures Act (APA) places constraints on when petitioners may present evidence and arguments against the patentability of claims during inter partes review (IPR). In particular, the Federal Circuit found that the APA requires that patent owners be given notice and a fair opportunity to respond to evidence or arguments put forward by petitioners in an IPR.
