John Berryhill Shares Thoughts About ENS TM Infringement

John Berryhill is an Intellectual Property attorney who specializes in domain name law. Last night, John posted a Twitter thread regarding trademark infringement, specifically related to ENS domain names. In the thread, John shared some thoughts about the potential issues that may come with owning ENS domain names that infringe on trademarks and brands.

Obviously, every domain name is unique, and there may be unique circumstances related to each domain name registration. Reading John’s thread would be a good idea for people who own ENS domain names that could potentially match well-known brand names and trademarks:

  1. I registered my best single word .com names as ENS domains. When ETH gas fees are low, registering a name for 10 years at $5/year renewal isn’t too bad. If I develop a .com, I’ll want the .eth version and I’d imagine a potential buyer may as well. I’ll reevaluate these purchases in 10 years. I also claimed the names in HNS (Handshake), which have no renewal fees. Although Unstoppable Domains is just a for-profit fork of ENS, I grabbed a few of their .nft domains as well (also no renewal fees). Other notable blockchain domains include Solana (.sol), Tezos (.tez), etc. If you’re a domain investor/developer and don’t understand the utility of blockchain domains or web3 in general, I’d highly recommend looking into it.
