The Perseverance of a Trademark Troll
Sockatume writes "Eurogamer has published an article on Tim Langdell's battle against the Edge iPhone game. Langdell, a British entrepreneur, founded Softek (later renamed The Edge, Edge Games and Edge Interactive Media Inc.) in the 1980s as a venture to fund game development, with profits to be split 50/50 with the developers. He moved to California in the 1990s in the wake of accusations of failing to pay his developers. Now a professor in games studies at National University, an IGDA board member, and a former member of BAFTA-LA's board, 'Dr.' Langdell spends his time accusing people of infringing his trademarks and offering to settle. After delivering a settle-or-die ultimatum to Edge publisher Mobigames (detailed in the article), he has convinced Apple to pull the game from the App Store. Mobigames is preparing to strike back: their lawyer believes that his trademarks are 'liable to be revoked.' Langdell has had a spate of bad press lately as other trademark disputes come to light, involving entities ranging from EA Games to Britain's venerable Edge Magazine (source of Edge Games' logo and now registering its own Edge trademark). He has never actually prevailed in a trademark hearing."
I'm not sure you're familiar with trademark law in the United States either. Your definition of "use" is unclear and its applicability in this case is questionable.
Let's see what the experts say: http://cyber.law.harvard.edu/metaschool/fisher/domain/tm.htm
So the trademark "Edge" in reference to games is, given the history of the company, inherently distinctive and thus fulfills the requirements for being a trademark.
Again, Langdell seems to have this base covered so far as anyone can prove.
Here we get to the crux of your post.
But if you take a look, Edge Games has a website, claims to be developing games, and is in no way abandoning its trademark to genericity. So while your claim that Edge Games hasn't released something for years may be true, it may not be relevant.
