The ruling is a modest procedural win for Apple (affirming non-obviousness of key claims) but also a setback (vacatur of obviousness ruling on other claims remands uncertainty). The underlying litigation remains stayed, so no immediate operational or financial impact. Monitor the PTAB remand proceedings and any subsequent district court activity for potential settlement or trial developments.

Executive Summary
The Federal Circuit affirmed the PTAB's finding that Apple failed to prove certain claims of Smart Mobile's wireless-device patents unpatentable, adopting a narrow construction of 'multiplexed signals' that excludes sequential transmission. However, the court vacated the Board's obviousness ruling on other claims due to inadequate consideration of Smart Mobile's bottlenecking argument, remanding for further proceedings. The ruling maintains the status quo in the underlying patent litigation, which remains stayed pending the IPR outcome, and does not impose any damages or injunctive relief on Apple.
Court Ruling Details
Key Facts
- Federal Circuit affirmed PTAB's implicit construction of 'multiplexed signals' as requiring a composite signal sent simultaneously along a single shared pathway, excluding switching/sequential transmission.
- Court affirmed Board's finding that Apple failed to prove claims 1-13, 27-30 of '653 patent and claims 1-13, 16, 26 of '946 patent unpatentable.
- Court vacated Board's obviousness ruling on claims 17-21, 23-26 of both patents and remanded for further consideration of Smart Mobile's bottlenecking argument.
- Underlying district court litigation (Smart Mobile v. Apple, C.D. Cal.) remains stayed pending resolution of the IPRs.
- No damages awarded, no injunction issued, and no financial exposure quantified in the opinion.
Financial Impact
No damages, injunction, or financial exposure stated in the opinion. The ruling preserves the status quo in the stayed patent litigation.
Risk Factors
- On remand, the PTAB could reverse its obviousness finding on the vacated claims, increasing Apple's exposure in the stayed district court litigation.
- If the district court litigation resumes and Apple is found to infringe valid claims, it could face royalty obligations or an injunction on certain wireless features.
- The nonprecedential nature of the opinion limits its value as precedent for other Apple patent challenges.
