The Verdict & Legal Analysis
Outcome
The Federal Circuit issued a clear disposition: **AFFIRMED**. The court upheld the prior finding that the asserted claims of **U.S. Patent No. 7,825,537 B2** are **unpatentable**. No damages were awarded, and no injunctive relief was granted — consistent with an invalidity ruling that extinguishes the patent’s enforceability entirely.
Verdict Cause Analysis
The case was decided on **patentability grounds**, classified as an invalidity/cancellation action. The Federal Circuit’s affirmance signals that Scramoge failed to overcome the prior tribunal’s invalidity findings on appeal. The inductive power transfer field is densely populated with prior art dating back decades, making wireless charging patents particularly vulnerable to obviousness and anticipation challenges.
