Short Summary
Headwater Research LLC seeks Director review of an IPR decision that found all claims of its 2013 MMS messaging patent unpatentable. The patent owner contends the Board improperly relied on expert testimony because the cited prior art (TS-23.140) does not disclose the required agent communication bus. The request asks the Director to vacate the decision and terminate the IPR.
Detailed Summary
In a Request for Director Review, Headwater Research LLC challenges the Patent Trial and Appeal Board’s Final Written Decision that declared all claims of U.S. Patent No. 8,406,733 unpatentable. The patent owner argues that the Board violated statutory requirements under 35 U.S.C. §311(b) by allowing the petitioners—Samsung Electronics, Google, and Samsung Electronics America—to rely on expert testimony to fill gaps where the sole prior‑art reference, TS-23.140, fails to disclose the “agent communication bus” limitation required by the claims. Citing Board regulations and Federal Circuit precedent, Headwater requests that the Director vacate the decision and terminate the IPR, or alternatively find the challenged claims unpatentable. The filing underscores the importance of strict adherence to prior‑art‑only grounds in inter‑partes reviews.
