Did CMU sit on patent like a troll?

摘要

An interesting point in the Carnegie Mellon University (CMU) infringement case, unlike some patent infringement cases, is that the CMU litigation did not arise from a business deal between the two entities that soured, and the university never licensed or otherwise practiced the patent. That led some industry watchers to charge that CMU was gaming the system, sitting on the patent and just waiting for an unsuspecting company to use it without permission. "Non-practicing entity" is the polite term. "Patent troll" is the other.
