Sony filed a trademark and service mark for "PlayStation TV" on June 26, covering hardware and potential related services, such as streaming television or movies, an IGN reader spotted. Sony held a trademark and service mark for "PlayStation TV" in September 2006, but it was abandoned in September 2012. Both marks feature the same logo and share features protected under the filings.
Sony didn't manufacture a PlayStation TV in the six years it held the first trademark, though it did launch a PlayStation-branded 3DTV in 2011. Recall that Sony holds the patent for a system that turns ads into interactive mini-games, asking viewers to yell out company names such as "McDonald's!" to end commercials.
