Two of the industry's heaviest hitters on Wednesday filed amicus curae ("friend of the court") briefs with the Court of Appeals for the Federal Circuit (CAFC) in support of Apple's position in its appeal over the dismissal last year of a two-way lawsuit with Motorola over patents and FRAND licensing. Microsoft and Intel, who were not involved in the original case, have filed briefs with the court supporting Apple's position that companies should not be allowed to sue over possible infringement of FRAND-eligible patent use.
