Domain registration ≠ trademark rights. 34% of US businesses register domain but skip USPTO trademark filing. Vulnerable to legal challenges from trademark holders.
Domain vs Trademark Rights
Domain: Right to use YourBrand.com web address. Trademark: Right to use "YourBrand" name in commerce for specific goods/services. Domain doesn't grant trademark protection. Need both for complete brand ownership.
Search Before Registering Either
Check USPTO database (tmsearch.uspto.gov) before domain registration. If trademark exists, don't register matching domain - legal liability. Check domains before trademark filing - competitor owning .com might block your trademark.
Search Scope
Search: Exact name, phonetic equivalents, visual similarities. "Accme" too close to "Acme" trademark. "Akmee" might conflict phonetically. Comprehensive search costs $300-800 (attorney service).
Registration Sequence
Step 1: Trademark search (USPTO + common law). Step 2: Register domain immediately if clear. Step 3: File USPTO trademark application within 30 days. Step 4: Monitor application through 8-12 month process.
Timing trap: Register domain before trademark filing but not 6+ months before. Need "bona fide intent to use" when filing. Long domain ownership without business use can be questioned.
Trademark Classes Affect Domain Use
Trademark registered in Class 25 (clothing). Doesn't stop someone using same name in Class 9 (software) with same domain. Domain registration is class-agnostic. Trademark protection is class-specific.
Intent-to-Use Applications
USPTO requires "bona fide intent to use" trademark in commerce. Evidence: Domain registration, website mockups, business plan, supplier quotes. Can't trademark squat (register with no business intent).
Domain Proves Use-in-Commerce
USPTO requires proof of actual commercial use for trademark registration. Live website on registered domain showing goods/services for sale = strong use evidence. Parked domain = insufficient.
Specimen Requirements
USPTO needs "specimen" showing trademark used in commerce. Screenshot of YourBrand.com selling products with brand name visible = acceptable specimen. Domain registration alone ≠ use in commerce.
Common Law Rights
Using domain+brand in commerce creates common law trademark rights even without USPTO registration. But: Limited to geographic area of actual use. Federal registration (USPTO) grants nationwide rights.
Geographic limitation: Common law rights protect YourBrand.com in Texas if you operate there. But competitor can use same name in California if you have no federal trademark.
Domain as Trademark Evidence
Early domain registration date proves priority of use. If trademark dispute arises, domain WHOIS showing 2020 registration date vs competitor's 2023 use = you have priority (if you can prove commercial use since 2020).
Defensive Domain Registration
After USPTO trademark approval: Register .com, .net, common misspellings. Trademark grants legal right to stop infringing domains. But proactive registration cheaper than legal battles.
Opposition Risk
USPTO trademark application publishes for 30-day opposition period. Existing domain owner in different industry might oppose (even if you registered domain first). Trademark examiner reviews objections.
Abandonment Through Non-Use
Domain registration lasts as long as you renew. Trademark requires continued commercial use. 3 years non-use = presumed abandonment. Can lose trademark but keep domain (or vice versa).
International Considerations
USPTO trademark protects in US only. Domain (.com) is global. Operating internationally? File trademark in other countries or use Madrid Protocol for multi-country filing. Cost: $1,000-3,000 per additional country.
