Ethereum Name Service (ENS) has asked the United States Patent and Trademark Office (USPTO) to challenge the validity of a patent obtained by Unstoppable Domains (UD) in 2023. ENS claims that UD’s patent uses technology that ENS developed and is open source. .
In a statement on social media platform X, ENS explained that UD had obtained a patent for technology developed by ENS Labs with the aim of being open source.
ENS Update 🧵: In 2023, Unstoppable Domains (UD) was granted a patent for ENS Labs technology developed in open source. Today we petitioned the USPTO to challenge the validity of this patent and ensure the web remains a collaborative space. Here’s why and what the issues are. pic.twitter.com/Qxls0kkP6G

Both ENS And OF providing domain name and wallet services with top-level domains (TLDs) such as .crypto, .eth and similar brand names that form an affinity with the crypto space. ENS alleges that UD patented “ENS’ pioneering technology, directly leveraging our open source innovations” and that ENS’ contributions were even cited in the patent.
“We gave UD every chance to avoid this battle: UD refused to open the patent and refused to make irrevocable commitments not to use the patent to the detriment of the community,” ENS said.
In response to the petition, Unstoppable Domains founder Matthew Gould said on X that the patent had been reviewed by the examiner with citations to the ENS in place. Gould argued that patents are valid and that “patent filing is very common in both the Web3 and domain industries.”
On this subject, Nick Johnson, the lead developer of ENS, asked Gould to cite the key innovation in UD’s patent that was not already part of ENS.
Maybe you could summarize, Matt, for all the Twitter users who don’t have time to read the entire patent. What is the key innovation covered by your patent that was not already part of the ENS?

As of this writing, Gould has yet to respond to Johnson’s question, a lack of response for which Johnson posted two cricket emojis.
In his initial response to the ENS thread, Gould claims that Unstoppable Domains has several other patents pending and that he will continue to file patents to “protect” the company. Gould also mentions that his company committed to not reporting more than a year ago and considers the issue resolved.
In July 2022, Unstoppable Domains raised $65 million in a Series A round led by Pantera Capital, propelling the company’s valuation to unicorn status at $1 billion. The ENS, for its part, operates on the basis of a set of decentralized smart contracts for an open and public infrastructure.
