The Federal Circuit held that forfeiture principles apply even when a corrected inventorship certificate would have changed a PTAB proceeding's outcome, requiring parties to raise inventorship arguments and seek corrections diligently in the first instance.

Section 256 allows patent invalidation to be prevented through inventorship correction without express timing requirements, but the Federal Circuit ruled forfeiture principles can bar delayed corrections from supporting new arguments in inter partes review.
