On January 8, 2016, the U.S. Court of Appeals for the Federal Circuit (CAFC) decided the case of Wi-LAN, Inc. v. Apple, Inc. where Wi-LAN, owner of U.S. Patent No. RE37,802, sued Apple for infringing certain claims of its ‘802 patent. A jury found that Apple did not infringe and that the claims are invalid. Because the issue of invalidity was directed to a mere procedural matter on appeal, this Newsletter limits its discussions on the issue of infringement.
- Claim 1 of the ‘802 patent recites as follows:
- 1. A transceiver for transmitting a first stream of data symbols, the transceiver comprising:
a converter for converting the first stream of data symbols into plural sets of N data symbols each;
first computing means for operating on the plural sets of N data symbols to produce modulated data
symbols corresponding to an invertible randomized spreading of the first stream of data symbols; and
means to combine the modulated data symbols for transmission.
