Check trademark
check_trademarkLook up live identical or very similar word marks for a name in USPTO and EUIPO. Read-only. Does not charge. Works with no account. Each hit includes its Nice classes. When intended_use is given, each hit also includes a relevance note for that use. Tell the human the Nice classes and any relevance note, not only that a mark exists. The result lists the registers that answered and the ones not checked. USPTO is checked. EUIPO is checked only when keys are set. National offices are not checked; the result includes a TMview link for them. This is not legal advice.
