FiftyThree, the company behind popular iPad sketching app Paper, has filed for a trademark on the term "Paper" following the announcement of Facebook’s magazine-style news curation tool, also named Paper.
First discovered by TechCrunch, the trademark was filed with the United States Patent and Trademark Office on January 30, the same day Facebook initially unveiled its new app. As noted by FiftyThree co-founder Georg Petschnigg in an open letter, FiftyThree was not given advanced notice of Facebook’s plans and was taken by surprise by the app release.
