United Video Properties, which owns TV Guide and Rovi, decided it wanted a prime cut of Amazon for infringing 6,769,128 & 7,603,690. Carefully biased claim construction insured noninfringement. The lynchpin was prosecution estoppel. Ironically, a term was struck ("Internet delivered data") during prosecution that actually broadened claim scope. But of course, with Amazon being the target, the court skewed claim construction to get Amazon off the hook. (CAFC 2013-1396).
