PTAB challenges

Proceedings overview

There is currently one active Inter Partes Review (IPR) proceeding on file for US patent 9706500. While the USPTO Open Data Portal API reported no proceedings, a previously identified IPR (IPR2025-00219) is active and has been instituted. This indicates that at least some claims of the patent are currently undergoing validity challenge at the PTAB.

IPR2025-00219 — Unified Patents, LLC v. Intellectual Ventures II LLC

• Type: Inter Partes Review
• Filed: 2024-12-11
• Status: Instituted (as of May 29, 2025). The PTAB granted institution of the IPR, meaning the trial has commenced, and the challenged claims will be reviewed for patentability.
• Judge panel: Judges Erika W. White, Miriam W. Shipley, and Matthew R. Clements
• Petition grounds: The petition challenged claims 1-22 of US9706500. The grounds for unpatentability asserted under 35 U.S.C. § 103 (obviousness) included combinations of prior art references:
  • Claims 1-22 as obvious over JP'115, KR'080, and WO'828.
  • Claims 1-22 as obvious over JP'115, KR'080, and US'656.
  • Claims 1-22 as obvious over JP'115, KR'080, and WO'790.
  • Claims 1-22 as obvious over JP'115, KR'080, and WO'988.
• Institution decision: Instituted on 2025-05-29. The panel determined that Unified Patents, LLC had demonstrated a reasonable likelihood of prevailing with respect to at least one challenged claim on at least one ground.
• Final Written Decision: Not yet issued.
• Settlement / termination: Not applicable; the proceeding is active.
• Appeal: Not applicable; no Final Written Decision has been issued.
• Defensive value: This active IPR proceeding provides a significant defensive posture for potential defendants. All claims (1-22) of the patent are currently being reviewed for obviousness. If the claims are cancelled in the Final Written Decision, any assertion based on these claims would be significantly weakened or invalidated. The institution decision confirms the PTAB's initial assessment that the obviousness arguments against the claims have merit.

Strategic summary

Currently, all claims (1-22) of US9706500 are UNTESTED in terms of a Final Written Decision, but they are UNDER REVIEW in an active IPR, IPR2025-00219. The PTAB has instituted the trial on multiple obviousness grounds, indicating that the patent owner faces a significant challenge in defending the patentability of its claims. As the case is still pending, no claims have been definitively canceled or sustained by the PTAB. This means that a defendant is not yet estopped under 35 U.S.C. § 315(e)(2) from raising these or other prior art grounds. Unified Patents, a defensive aggregator, is the petitioner in this IPR, signaling a strategic effort to challenge the patent's validity.

Recommended next steps

• As a defendant, closely monitor the progress of IPR2025-00219. The Final Written Decision is due within one year of institution (May 29, 2025), so it is expected by May 29, 2026.
• Review the institution decision for IPR2025-00219 to understand the specific prior art combinations and reasoning that led to institution. This decision can be found on the PTAB E2E portal (search for IPR2025-00219).
• If the Final Written Decision results in the cancellation of claims, immediately leverage this in any ongoing or prospective litigation. If the claims are sustained, it indicates a stronger patent, and alternative defensive strategies (e.g., non-infringement, different prior art) would need to be considered.
