Inter Partes Review

Erise attorneys have been winning IPRs since day one. We represented the Petitioner in the first IPR ever filed. Since then, Erise is consistently ranked among the best-performing firms at the Patent Trial and Appeal Board (PTAB) for IPR petitioners in Patexia’s independent ratings. Our attorneys also rank among the best-performing and most active PTAB attorneys in the country.

Erise attorneys recognize that there is little room for error in IPRs. Nuances of the technology, motivations to combine, and the potential arguments from the opposing side must be stress tested and solidified early in the process.

In constructing IPRs for the best possible success, Erise stands out for these reasons:

• In-house prior art searching: Because IPRs are only as strong as the prior art that supports them, Erise uses an internal search team to dig for the most relevant and hard-to-find prior art and to structure a ground that tells a story with the motivations to combine.
• Experienced teams: Our senior team members are substantively engaged, contributing their vast experience from day one. When our attorneys put their name on an IPR, they are fully invested in the matter, understand the subtleties involved, and drive strategy and drafting throughout the process.
• Litigation knowledge: Our IPR attorneys are well-versed on the interplay between IPRs and litigation, often serving as both litigation counsel and PTAB counsel. We also frequently work with separate litigation counsel to navigate the tensions that arise from parallel actions. Whatever the counsel arrangement, we excel in identifying viable solutions to thorny issues, such as means-plus-function claims, indefiniteness, and claim construction.

We’re nimble, easy to work with, and passionate about winning, And we truly enjoy the challenge of IPRs and appreciate the potential of an IPR to favorably impact parallel litigation.
