Recently the popular iPhone indie game Edge was pulled away due to a lawsuit from Tim Langdell of Edge Games. This guy was previously a relatively obscure figure but the event sparked some interest in his history in the industry. Turns out that around the early 90's, he switched focus from developing games to suing anyone using the word edge in their titles.
Edge Games has not released any game since 1994 and has supposedly staid afloat purely from lawsuits and forcing people into licensing fees. He's the reason Soul Edge was renamed to Soul Blade/Calibur outside Japan for example.
The devs for the iPhone Edge suggested renaming it to Edgy, promptly after that Tim decided to trademark Edgy as well. Sounds like a great guy, huh?
