The company made the filing May 18 with the United States Patent & Trademark Office. The trademark application is registered to Sony Pictures Television, but also appears to be tied to gaming.
It covers two good/services, the first of which is "downloadable electronic game software; video game software." While the second specifically mentions "entertainment services in the nature of a dramatic television series."
No further information about The Player is available in the filing, though the document also includes the image you see below.
Sony has used the word "Player" before in marketing materials for the PlayStation 4, as you can see here. We've followed up with Sony, asking for more details about The Player.
The filing was published less than a month before E3 is scheduled to begin next month. Sony closes out Monday, June 15's events with its show at 6 PM PDT in Los Angeles. GameSpot will bring you all the news from the event as it's announced. For more on E3 2015, check out GameSpot's roundup of the dates and times for all the E3 events.
