the trademark for Cybernet's "Edge of Extinction" game assigned to Edge Games, and his further right to require Cybernet to enter into a paid license agreement with him due to their use of the name. Cybernet refused, and when Langdell threatened a lawsuit, Cybernet instead filed suit against Edge.[50] "Edge of Extinction" was released in 2001, and is no longer an active game.[51][52]

As of June 1, 2009, Edge Games applied for a US trademark for the phrase, "Edge of Twilight."[53] This is the name of an upcoming steampunkfantasy game that has been in development by Fuzzyeyes Studios for at least two years.[54][55]

In 2014, Edge Games began a trademark case against the game peripherals company Razer, regarding its Razer Edge gaming tablets. Edge filed an application for "SL8" intablets in 2012, serial number 85704825, indicating that it would sell Windows 8 tablets at some point.[63] The application was eventually denied,[64] while Langdell's subsequent attempts to trademark hardware under the "EDGE PC" name have been suspended.[citation needed]

In July 2009, members of the International Game Developers Association (IGDA) began circulation of a petition calling for a special meeting of the membership to vote on the removal of Langdell from that organization's board of directors citing, among other things, his use of his position on the IGDA to "work directly against the mission of the organization."[65][66] In late August, the IGDA announced that a special meeting of the membership would be held on October 3, the sole purpose of which was to vote on whether Langdell should be removed,[67]
