In addition to federal court litigation, Arch & Lake LLP represents clients in post-grant proceedings before the Patent Trial and Appeal Board (PTAB), including inter partes review (IPR), post-grant review (PGR), and ex parte reexamination (EPR). Our team has handled more than twenty PTAB proceedings, often in parallel with district court litigation as part of a coordinated patent dispute strategy.

PTAB proceedings require a unique blend of litigation strategy, technical expertise, and patent prosecution experience. Our attorneys combine these skills to develop effective challenges and defenses of patent validity. By integrating PTAB proceedings into broader litigation strategies, we help clients strengthen their positions in ongoing disputes and achieve favorable outcomes in complex patent matters.
