Search worldwide patent publications via the European Patent Office's Open Paten
Search worldwide patent publications via the European Patent Office's Open Patent Services (OPS). Pass a CQL query (e.g. ti=quantum computing, in=tesla, pa=siemens, cpc=H01M, pn=EP1000000) and get matching publications with country, document number, kind code, and a combined publication number, plus the total result count. Covers EP + 100+ patent authorities worldwide — net-new vs our US-only patents.search.
