Nike trademarked "Just Do It" for shoes (Class 25). Metaverse requires separate filing for "virtual footwear" (Class 9). Same slogan, different product class. File virtual goods separately or unprotected.
Virtual Goods Classes
Physical goods ≠ virtual goods. Class 9: "Downloadable virtual goods." Class 35: "Retail services for virtual goods." Class 41: "Entertainment services in virtual environments." All separate filings.
The Marketplace Problem
Sell virtual sneakers on Decentraland. Counterfeiter sells knock-offs on Sandbox. Different platforms = different enforcement. No unified metaverse trademark system (yet).
NFT Complications
Trademark NFT artwork. Owner resells NFT. Does trademark transfer with NFT? Contract must specify IP licensing vs ownership. NFT ≠ automatic IP transfer.
Physical-Virtual Coordination
Real-world "Nike" trademark ≠ automatic metaverse protection. Hermès sued "MetaBirkins" NFTs (won). But required litigation. Pre-emptive virtual filing cheaper than lawsuit.
Specification Challenges
"Virtual clothing" accepted. "Digital fashion items for avatars" accepted. "Metaverse wearables" = examiner confusion (too new). Use established terminology or face objections.
The Platform Risk
Register trademark for virtual goods on "Second Life." Platform shuts down. Trademark exists but no marketplace. Diversify across platforms or risk obsolescence.
Enforcement Tactics
Counterfeit virtual goods? Platform takedown notices (like eBay/Amazon). DMCA for NFT marketplaces. Traditional trademark litigation for persistent infringers. Digital ≠ lawless.
Trademark Lens checks physical goods trademarks - virtual goods require separate search across "downloadable virtual goods" classes.
