Do you remember the VHS-Betamax war? This was the epic struggle between home video recording technologies. By most standards, Sony's Betamax format was considered the best. In the end, however, VHS (Video Home System) claimed the field. Key in the fight was the fact that the formats were device-exclusive. Betamax tapes didn't run on VHS machines and vice-versa.

Strategic thinking that leads to an overall plan for managing intellectual property is essential. And part of that plan needs to be a determination of what to do with any given patent.
