U.S. Court of Appeals for the Federal Circuit
Apple Inc. v. Smart Mobile Technologies LLC
August 27, 2026
Summary
The Federal Circuit affirmed the Board's final written decision rejecting Apple's challenge to claims 1-3 and 5 of Smart Mobile's patent as obvious. The court upheld the construction of "multiplexing signals" as "combining multiple signal streams into one" and concluded that substantial evidence supported the Board's finding that the asserted prior art did not disclose that limitation. No separate opinions were issued.
