Erise Secures an IPR Win for Client Sony at PTAB


Erise shareholder Eric A. Buresh, along with counsel Jason R. Mudd and senior technical advisor Kathleen D. Fitterling, recently successfully represented the petitioner, tech giant Sony Interactive Entertainment, in a recent inter partes review (IPR) proceeding. 

The underlying case was first filed by Bot M8 in 2019, alleging that Sony’s PlayStation 4 console and games infringed five of its patents, including the subject patent related to a “gaming apparatus with memory fault detection.” In October, the Patent Trial and Appeal Board (PTAB) found all challenged claims to be unpatentable under all grounds presented by the Erise team.
