Short Summary
The PTAB remand decision held that all 23 claims of Omni MedSci’s wearable pulse‑oximetry patent are unpatentable, applying 35 U.S.C. § 103 obviousness over multiple prior‑art references.
Detailed Summary
In a Final Written Decision on Remand for IPR2021‑00453, the Patent Trial and Appeal Board affirmed the claim‑construction that “identify an object” means to recognize or establish an object as a particular thing. The Board then applied an obviousness analysis under 35 U.S.C. § 103, finding that the combination of prior‑art references—Lisogurski, Carlson, Tran, Isaacson, and Valencell‑093—disclosed each limitation of claims 1 through 23 of Omni MedSci’s wearable pulse‑oximetry patent. Petitioner’s expert testimony demonstrated a motivation to combine these teachings. As a result, all challenged claims were declared unpatentable.
