California-based NovaLogic, the developer behind the tactical shooter series, is seeking damages and an injunction for trademark infringement against Activision, after alogo was used in the story forNovaLogic'sfranchise began in 1998, and has since seen nearly a dozen installments, including the upcomingfor Windows PC. As part of Activision's best-selling, released last year, the game features a Delta Force army division.In NovaLogic's complaint, filed in Los Angeles, the company says that it owns thecopyright, and alleges that Activision continued to use thename indespite multiple warnings from NovaLogic.In particular, the company points out that the logo for's Delta Force division is very similar to the logo for NovaLogic'sseries, both depicting a knife behind a triangle with a lightning bolt."The infringing mark's lightning rod is horizontal rather than vertical and a portion of the delta sign is set behind the dagger blade rather than being superimposed," reads the complaint [PDF] , as reported by Courthouse News.It continues, "Despite Activision's irrefutable knowledge of NovaLogic's superior trademark rights, Activision created knockoff marks that are nearly identical [to] NovaLogic's design and word marks. Activision then shamelessly inserted these infringing marks throughout its competing first person military adventure video games."The complaint goes on to allege that Activision then licensed the name and mark out to hardware manufacturers Turtle Beach and Microsoft, and the BradyGames division of Penguin Books without NovaLogic's permissions -- all of whom are included in the lawsuit.As part of the complaint, NovaLogic stresses that thename is allegedly not part of the U.S. Army, or in any way associated with it."There is no unit of the U.S. Army called Delta Force," it says, "There is a branch of the Army's Special Operations known as 1st Special Forces Operational Detachment Delta ('1st SF-ODD'). The U.S. Army officially denies that any unit called Delta Force exists and does not claim ownership to either the Delta Force name or the logo.""Although there is much lore surrounding special operation units, only because of theseries does the general public identify the logo with any ancillary existing military unit," it states.NovaLogic "has lost millions of dollars, possibly more," due to the conduct of Activision, it alleges. As a result, it is seeking damages and an injunction for trademark infringement against the company. Gamasutra has contacted Activision for comment.
