A Trademark Registration from Valve Corporation dated yesterday is for a computer game called DEADLOCK (thanks Tyler McVicker). This fits in with recent fairly rampant rumors that Valve is creating a 6v6 multiplayer third-person shooter using that very title. This all seems too pat to be coincidental, but nothing is confirmed yet, although we are heading into the most announcement-heavy time of year. Here's the boilerplate description from the filing:
Mark For: DEADLOCK™ trademark registration is intended to cover the categories of entertainment services, namely, providing online video games; provision of on-line entertainment, namely, on-line computer games; entertainment services, namely, providing on-line computer games and on-line video games; electronic games services provided by means of the Internet; providing information in the fields of computer games and entertainment via the Internet; organization of competitions relating to video games, video game education, and video game entertainment; providing information in the field of on-line computer games and on-line video games and computer games.
