Short Summary
Entropic Communications seeks Director review to deny institution of Comcast’s IPR, arguing the petitioner’s repeated filing of parallel petitions violates USPTO guidance and burdens the PTAB. The request cites statutory discretionary‑denial authority to block the abusive filing pattern.
Detailed Summary
In a request for Director review of the Institution Decision in IPR2025-00180, Entropic Communications contends that Comcast Cable Communications has engaged in a systematic abuse of the inter partes review process by filing multiple parallel petitions against the same patent, despite clear USPTO guidance issued in 2019 that such conduct is “unlikely” to be appropriate. The patent owner points to Comcast’s history of filing three or more petitions per patent, the Board’s prior denials of similar petitions, and the lack of new justification for the current filings. Citing 35 U.S.C. §§ 314(a), 314(d), and 316(a)(6), Entropic urges the Director to deny institution to enforce the discretionary‑denial framework, preserve PTAB resources, and deter future harassment of patent owners.
