Google Patents** - the first place to go. Full text across 120M+ patents and applications, Google-style interface, and the AI \"similar documents\" / prior-art finder catches semantic matches keywords miss. Also pulls in Google Scholar for non-patent literature, which matters because academic papers kill patents just as dead as patents do. Free.\n\n**2. Espacenet (EPO)** - your second pass, and the one patent professionals actually trust for completeness. ~150M documents from 100+ patent authorities. Its killer feature is the citation view: all citations for an entire patent family on one page, split into inventor vs. examiner citations. Examiner citations are gold - they're what a real examiner thought was relevant prior art.\n\n**3. WIPO Patentscope** - worth a specific visit for PCT applications and its cross-lingual search, which translates your query to find foreign-language prior art you'd otherwise never see. Chinese and Japanese filings are a common blind spot.\n\n**4. Lens.org** - free, nonprofit (Cambia/QUT), ~140M records.
