Motion to Amend: Much to Admire?, PTAB Litigation Blog
Visit the PTAB Litigation Blog
Motions to amend (MTA) are becoming a more frequently used tool for patent owners litigating before the Patent Trial and Appeal Board (PTAB). When a patent is being challenged in an inter partes review (IPR) or post-grant reviews (PGR) before the PTAB, the patent owner has the option of filing a motion to amend the patent’s claims. Such MTAs, however, were rarely granted in the beginning years of the American Invents Acts. But over the past few years, the PTAB has enacted a MTA Pilot Program that favors patent owners’ use of this procedure.
