The America Invents Act (AIA) significantly expanded the options available for challenging issued patents. The AIA created new administrative procedures at the U.S. Patent & Trademark Office, and replaced the Board of Patent Appeals and Interferences with the Patent Trial and Appeal Board (PTAB). The new procedures, including Inter Partes Review and Post-Grant Review, are fast, adversarial, and subject to statutory bars.  We also have substantial experience with traditional post-grant proceedings, including Interference and Ex Parte Reexamination. Pierce Atwood combines technical expertise and litigation acumen to represent its clients before PTAB with a singular focus — achieving our clients’ business goals.
