Trademarks protect marks within their own categories, which can loosely be defined as fields or industries. However, some categories, like IC009, which covers downloadable software, is very broad. As technology becomes increasingly—and sometimes overwhelmingly—pervasive, "downloadable software" touches so many different industries. What company doesn't have their hand in downloadable software? There is at least one company in every possible industry with some form of downloadable software, like a mobile app. Does the USPTO distinguish between downloadable software?
For instance, I want to trademark a name for a social network (via mobile app) targeted to a specific segment of consumers. However, that name is trademarked by a video game company for their video-game development software. From a software engineer's perspective, there is no reasonable link between internal software used by developers and a social network used by consumers. But does the USPTO feel the same way? Or is downloadable software just downloadable software?
