Monitor the PTAB's decision on remand regarding claim 17 of the '653 and '946 patents. A finding that claim 17 is not obvious would strengthen Smart Mobile's position and could increase settlement pressure on Apple. The stayed district court litigation is the next major catalyst; watch for any lifting of the stay or trial date setting.

Executive Summary
The Federal Circuit affirmed the PTAB's decision that Apple failed to prove claims of Smart Mobile's '075, '653, and '946 patents unpatentable as obvious, upholding a narrow construction of 'multiplexed signals' that excludes switching. The court also vacated and remanded the Board's finding that claim 17 of the '653 and '946 patents is obvious, citing inadequate consideration of Smart Mobile's bottlenecking arguments. This is a partial loss for Apple, keeping key patent claims alive and the underlying district court litigation stayed but unresolved, while the remand on claim 17 offers a potential path to narrowing the asserted patent scope.
Court Ruling Details
Key Facts
- Federal Circuit affirmed PTAB's rejection of Apple's IPR challenges to claims 1-3 and 5 of Smart Mobile's '075 patent (nonprecedential).
- Federal Circuit affirmed PTAB's rejection of Apple's IPR challenges to claims 1-13, 27-30 of '653 patent and claims 1-13, 16, 26 of '946 patent.
- Court vacated PTAB's finding that claim 17 of '653 and '946 patents is obvious, remanding for further consideration of Smart Mobile's bottlenecking arguments.
- Underlying district court litigation (Central District of California) remains stayed pending resolution of IPRs.
- Opinions are nonprecedential, limiting their impact to this specific case and related patents.
Financial Impact
No damages awarded; the ruling keeps Smart Mobile's patent claims alive, maintaining litigation risk and potential future royalty exposure for Apple. Financial exposure not quantified in the opinion.
Risk Factors
- Smart Mobile may seek to lift the stay in district court following the Federal Circuit's affirmance, resuming infringement litigation.
- Remand on claim 17 creates uncertainty; if PTAB reverses on obviousness, Smart Mobile gains a stronger infringement case on those claims.
- Nonprecedential nature of opinions limits their value as precedent for other Apple patent challenges.
