Update: Overruled in part by Aqua Products, Inc. v. Matal. In a subsequent order, the court vacated the portions of the panel’s and the PTAB’s decisions concerning the patent owner’s motion to amend, and remanded the case to the PTAB for proceedings consistent with the Aqua Products decision.

In Phigenix, Inc. v. Immunogen, Inc., the Board issued its final written decision and held that each of the eight challenged claims were not unpatentable, finding the Patent Owner “advances persuasive evidence” regarding the prior failure of others and the long-felt need in the industry.
