Full-text search across US patents and applications. Save a patent as PDF and upload it — claims and specifications ground prior-art questions well.

Full-text search across US patents and applications makes this the place to check when a notebook needs to ground a prior-art or technology-history question in the actual patent claims, not just a summary. Saving a patent as a PDF and uploading it gives the notebook the real legal language to work from. Coverage is US-only, so a question about patent activity elsewhere needs a source like WIPO alongside it.

## Import into Gemini Notebook

1. Copy the link: https://ppubs.uspto.gov
2. In your notebook, click Add source → Website.
3. Paste the link and confirm — several links can be pasted at once, one per line.

**Tip:** Government sites publish authenticated PDFs of bills, filings and records — import those directly rather than a search results page.
