Post-Grant Review

Law360 recently named Erise as one of the top 20 “go-to” firms in the United States for its work at the Patent Trial and Appeal Board (PTAB). Data analytics firm Patexia, in its 2021 IPR Intelligence Report, ranked Erise in the Top 20 best-performing firms for IPRs in the United States. Patexia evaluated data over a five-year period from July 1, 2015 to June 30, 2020, evaluating 915 law firms for overall IPR activity and success to develop a weighted average to determine the rankings.

Erise has a long history of unprecedented success at the Patent Trial and Appeal Board (PTAB). Erise attorneys filed the first-ever inter partes review (IPR) at the PTAB in 2013 on behalf of Garmin. Today, Erise attorneys have filed over 220 IPRs, with three Erise attorneys individually ranking in the Top 50 most active PTAB attorneys in the U.S. There is no other law firm in the country that comes close to the experience of Erise on an individual attorney basis.

Experience matters at the PTAB like few other venues. The rules and requirements are fast-changing, and the demands placed on petitioners are exacting. Yet, the PTAB, for those who know how to navigate the waters, remains by far the most efficient and effective path for resolution of patent disputes against your company. Erise is the preferred PTAB counsel for multiple Fortune 100 companies and we have exactly what it takes to lead you to victory in your most complex and high-stakes PTAB matters.
