You might have rolled your eyes when Apple mentioned that the iPhone 11 and 11 Pro could do “slofies,” but the company is taking things slightly more seriously. Apple has applied to the USPTO for a trademark on the term “Slofie” in terms of “downloadable computer software for use in capturing and recording video.” Don’t worry, it’s not trying to own the cultural landscape — rather, this is largely to prevent app developers and phone makers from ‘borrowing’ the term for their own features.

The word is silly and unlikely to catch on but Apple is CYAing just in case.
