Short Summary
ENS Labs Ltd. has filed a Petition for Inter Partes Review challenging Unstoppable Domains Inc.'s patent covering Domain Name Resolution (ENS) methods. The petitioner argues that the core claims are obvious under 35 U.S.C. § 103 by combining multiple prior art references related to blockchain functionality.
Detailed Summary
This Petition challenges twenty claims of Patent 11558344, asserting that the technology for ENS resolution is rendered obvious. The petitioner's central theory relies on combining foundational documents like Johnson and Millegan with various technical standards (EIP-137) and patents (Schneider, Haynes, Saini). These combinations are argued to predictably lead to methods of resolving an ENS name into a website address via the Ethereum blockchain.
