Senators John Cornyn(R-Texas), Chuck Grassley (R-Iowa), Richard Blumenthal (D-Conn.), and Dick Durbin (D.-Ill.) recently sponsored two bills, introduced on March 14th, that would affect patents in the pharmaceutical industry.

The Federal Circuit recently issued a decision in Kroy IP Holdings, LLC v. Groupon, Inc., No. 23-1359 (Fed. Cir. Feb. 10, 2025), holding that collateral estoppel does not preclude a patentee from asserting any unadjudicated claims of a patent where other claims of the same patent were held unpatentable in an inter partes review (“IPR”) by the Patent Trial and Appeals board (“PTAB”).

The Federal Circuit in Sanho Corp. v. Kaijet Technology International Limited, Inc., No. 2023-1336 (Fed. Cir. July 31, 2024) recently addressed the prior art exception of a “public disclosure” under 35 USC § 102(b)(2)(B).  Affirming a decision of the U.S. Patent Trial and Appeals Board (“PTAB”), the court held that “publicly disclosed” is only satisfied if the invention was made available to the public, and a non-confidential but otherwise private sale of an invention is not a sufficient “public disclosure”.  This case provides a cautionary tale that disclosing or selling an invention before filing a patent application is fraught with risk.
