Silicon Xtal Corp. of San Jose, Calif., has filed for a trademark on the term “SexBox” for a new adult-oriented video-game console, which plays Adult Only rated (AO) video game software titles.” The trademark description also explains the device may be used as a gateway to other adult entertainment and massive multiplayer online games. Wait, massive multiplayer adult games? The company behind the proposed device says they worked on the Xbox 360 hardware. Microsoft probably won’t be amused with their choice of name. The site CinemaBlend reports that Silicon Xtal says Apple and Microsoft have used its circuit designs, although that portion of the Silicon Xtal website was unavailable as of this morning, reports.
