A trademark filing by Sony Mobile suggests the company may look to launch its own mobile-centric cloud service in the future. Sony has applied to trademark the term "MyXperia" at the European OHIM (Office of Harmonization for the Internal Market), and the listing is available online for all to see.
The trademark application lists a number of mobile-based services for MyXperia, including “upload, storage, retrieval, download, transmission and delivery of digital content and media." That's a fairly vague definition, but it points to a possible proprietary Sony cloud service for exchanging photos, music and other data between Xperia phones and other devices.
Previously, Sony Mobile has relied on a partnership with Box.net to bring cloud storage to Xperia smartphone buyers.
The company also owns MyXperia.com, though currently that hosts nothing more than a nondescript login page.
With more and more mobile device manufacturers -- including Android giant Samsung -- getting into the cloud storage game, we wouldn't be too surprised to see MyXperia making an appearance on upcoming 2013 Xperia phones. Precisely what form it'll take, though, will remain to be seen.
