Software company Deno Land has filed a petition with the U.S. Patent and Trademark Office to cancel Oracle’s JavaScript trademark, citing trademark abandonment and fraud. The November 22 filing claims Oracle has not sold JavaScript products or services since acquiring the trademark through its 2009 Sun Microsystems purchase. The petition alleges Oracle committed fraud during its 2019 trademark renewal by submitting Node.js website screenshots without authorization.

The legal action follows a September open letter from JavaScript creator Brendan Eich, Node.js and Deno creator Ryan Dahl, and other prominent JavaScript developers urging Oracle to relinquish the trademark. The letter has garnered over 14,000 signatures.
