Paste a single claim sentence. We surface the closest twenty-five prior-art hits with diff-highlighted overlap, weighted by CPC class and assignee history — drawn from the USPTO Open Data Portal Beta, indexed weekly. Build window is narrow: the ODP Beta sunsets on May 29, 2026, after which the URL migration locks new entrants out for months.

Pasted-in claims stay in your browser session. We never persist drafts server-side. Embeddings used for similarity are computed transiently and discarded.
Standard NDA available on request. We're not a law firm; we don't review claims for novelty/non-obviousness — that's your job. We surface candidates so you can.
