Detailed Summary

In a petition for inter partes review (IPR2025-00377), iRhythm, Inc. challenges 26 claims of U.S. Patent No. 8,214,007 owned by Welch Allyn, Inc. The challenger contends that the claims are unpatentable under pre‑AIA 35 U.S.C. § 103 as they would have been obvious to a person of ordinary skill in the art (POSA) in view of the Jensen and Kroll references, together with general POSA knowledge, and, for certain claims, additional references such as DeLuca, Harland, and Thompson. The petition also addresses discretionary denial considerations under §§ 314(a) and 325(d), concluding that none of the factors favor denial. No claim construction or expert testimony beyond Dr. Jason Heikenfeld is presented. The proceeding is currently at the petition stage, awaiting a decision on institution.
