Patent Search is a specialized research skill for navigating the world of intellectual property. It queries public patent databases, analyzes patent claims and classifications, and produces structured reports on prior art and patent landscapes relevant to your technology area.
How It Works
- Invention disclosure parsing — Analyzes your technology description to extract key technical concepts and novel claims
- Database querying — Searches Google Patents, USPTO, and EPO databases using CPC classification codes and keyword combinations
- Claim analysis — Reads patent claims to assess overlap with your invention and identifies distinguishing elements
- Prior art mapping — Organizes found patents by relevance, filing date, and assignee into a structured landscape
- Report generation — Produces a prior art report with citation links, claim comparisons, and patentability assessment notes
