As we draw closer to Microsoft's October 26 event, a new trademark filing has outed what could potentially be the name of Microsoft's rumored all-in-one PC, which is expected to be unveiled at the event. As first spotted by The Trademark Ninja blog (via The Verge), it appears that Microsoft is behind a recent trademark filing for the name "Surface Studio," which was applied for through a Slovenian company that has been associated with Surface-related filings in the past.

'Surface Studio' could be the name of Microsoft's rumored all-in-one PC

Aside from the Surface Studio filing, it appears Microsoft is also behind filings for "Surface Laptop," "Paint 3D," "Surface Dial," and "Dial." While the Laptop filing is a bit perplexing, the filing for Paint 3D makes sense given that it's expected Microsoft is gearing up to launch a revamped version of its Paint app with 3D editing features.

It's always best to take these things with a requisite grain of salt, but the Surface Studio naming does seem to line up nicely with earlier reports that the all-in-one could "turn your desk into a studio." In any case, Microsoft's event kicks off right away at 7 a.m. PT / 10 a.m. ET on October 26, so we won't have to wait much longer to see if any of these filings turn out to be real products.
