The US Patent Trial and Appeal Board (board) has discretion whether to institute a trial on an inter partes review (IPR) or post-grant review (PGR) petition.
1 The board may deny institution for reasons unrelated to the merits of the patentability challenges. For example, the board
may deny a “follow-on” petition, filed by a second petitioner, after it has already considered an earlier petition, filed
by a first petitioner, when there is a “significant relationship” between the first and second petitioners. This article reviews
board decisions that identify factual circumstances that have led to a finding of a “significant relationship” and a discretionary
denial, and those that have not.
