The U.S. Patent and Trademark Office (USPTO) has upheld Unstoppable Domains' patent for blockchain domain technology, dismissing a challenge from ENS Labs. The Patent Trial and Appeal Board found that ENS Labs did not provide sufficient evidence of prior art or a threat to the patented technology. This decision affirms the validity of Unstoppable Domains' intellectual property, which facilitates the use of human-readable names for blockchain addresses through smart contracts. CEO Matt Gould emphasized that the ruling supports the integrity of their innovations and the broader Web3 ecosystem.
