Per the USPTO trademark database (on mobile so can&#x27;t readily link), FiftyThree has a trademark on &quot;Pencil by FiftyThree&quot;, not on &quot;Pencil&quot;. Moreover the trademark they do have specifically disclaims exclusive rights to the word &quot;pencil&quot; by itself. (IANAL but typically USPTO will ask for these sorts of disclaimers if part of the trademark is deemed generic&#x2F;descriptive.)<p>Similarly Apple&#x27;s product is officially named &quot;Apple Pencil&quot;.<p>So Apple is probably in the clear.
