Small companies can't afford to fight the big ones, so they tend to either back down or fight and go bankrupt before the case is concluded. Apple has done this

Small companies can't afford to fight the big ones, so they tend to either back down or fight and go bankrupt before the case is concluded. Apple has done this in the past -- one example is IIRC NuTech, assuming that I remember the company's name correctly. (They duplicated the mac.) PIXAR did it also with their patent on Catmull-Clark subdivision surface algorithms.
