Tim Langdell, the owner of Edge Games and the litigious defender of the trademark "Edge" has taken a serious thrashing in the UK courts at the hands of Future Publishing over its popular gaming publication, Edge Magazine. The company took Langdell to court in 2010 over breach of contract, breach of copyright, and misrepresenting the brand as belonging to Edge Games, causing brand confusion.
While the blow-by-blow is entertaining, it is also long-winded and mentally taxing to read as Langdell bobs and weaves in court, taking great liberties with the truth. If you are interested, Rock, Paper, shotgun offers an in-depth accounting of the court battle.
The short story is that Future Publishing wanted to avoid any litigation with Langdell so it reached a licensing deal with Edge Games that allowed them to use the "Edge" trademark. The deal started to crumble when Langdell started using Edge Magazine's logo on its letterhead and sent out documents that confused people as to the association between Langdell and Edge Magazine. Future filed a lawsuit against the company.
Needless to say, the judge sifted through all of Langdell's claims and evidence - including his assertion that he designed the original Edge logo. His "evidence" was a floppy disc that he claimed was from 1991, but it turned out that the disc was formatted using Windows 95. Windows 95 came out in... 1995. You can read the tap dance that followed that revelation in court at RPS. Langdell was stripped of his trademarks by a U.S. court for filing too many lawsuits.
