FAQ

Data sources: publicly published USPTO Trademark Trial and Appeal Board proceedings (1951–2026, with possible gaps before electronic filing) and U.S. federal court dockets (PACER/CourtListener, nature-of-suit codes 840 and 820). Figures reflect filings on record and do not characterize the merits, validity, or legitimacy of any individual action by Merck KGaA. Trademark holders have legal rights — and in some doctrines, an obligation — to enforce registered marks.
