*FORFEITURE PRINCIPLES APPLY WHERE § 256 CORRECTION HAS ISSUED
Implicit LLC v. Sonos Inc., 20-1173, 20-1174 — Yesterday in an opinion by Judge CUNNINGHAM, the Federal Circuit upheld a USPTO inter partes review decision that certificates correcting the inventorship of Implicit’s patents, issued after the final written decision, had no impact on the final written decision. Implicit argued the USPTO erred in finding it had forfeited its inventorship argument because corrections under 35 U.S.C. § 256 had a retroactive effect and no time limit in which they could be made.
The Federal Circuit disagreed. Implicit argued before the USPTO that the patent’s priority date preceded the prior art because the named inventors and a third-party engineer had reduced the invention to practice before the patents’ filing date. Implicit was required to act diligently in seeking to add the engineer as an inventor and assert its theory because such change could “directly affect the . . . outcome of the proceeding.” Its failure to do so earlier in amounted to forfeiture.

IPO FILES AMICUS BRIEF IN HIKMA V. AMARIN
Yesterday IPO filed an amicus brief at the U.S. Supreme Court in Hikma v. Amarin. IPO’s brief argued 1) the Federal Circuit applied the correct pleading standard; 2) there is no statutory basis for special pleading standards for Section VIII carveouts against induced infringement claims; 3) the Supreme Court has consistently cautioned against applying special, rigid standards in patent cases; and 4) the plausibility pleading standard preserves the statutory balance between generic competition and innovation.
IPO’s brief was drafted by PAUL BERGHOFF and TAYLOR WEILNAU (McDonnell Boehnen Hulbert & Berghoff LLP). IPO President JOHN CHEEK (Tenneco LLC), Amicus Brief Committee Chair Laura Sheridan (Google), and Deputy Executive Director & Chief Policy Counsel SAMANTHA GROVER were on the brief.
