Is the Presumption of Validity Dead in Substitute Claims Issued as a Result of Motions to Amend After PTAB Proceedings?
, Charles R. Macedo, Christopher Lisiewski, and Sean Reilly, September 28, 2018
A presumption of validity that is based on the assumption that government officials are presumed to have done their job is reasonable when a government office has been so tasked. However, in the context of amended claims coming out of an
inter partes review, the rationale falls apart. No presumption should remain for such claims, at least as long as the burden in an
inter partes review rests solely upon a petitioner with respect to substitute claims offered by amendment.
