When you’re working with patents, speed matters. Whether you’re an attorney drafting an Office Action response, a researcher tracking new developments in your field, or an engineer exploring related inventions, quick access to official USPTO publications can make or break your workflow.
That’s why we built PatPDFs — a free, streamlined tool for bulk-downloading U.S. patents and pre-grant publication PDFs, with optional OCR text layers that make your documents fully searchable and ready for analysis.
Why We Built It
Anyone who’s spent time downloading patents from the USPTO knows the pain:
- Searching one by one
- Finicky input formatting
- Inconsistent or expired PDF links
- Occasional server timeouts
PatPDFs automates all of that. Just paste a list of publication or patent numbers and click Fetch PDFs.
We’ll handle the rest — flexibly parsing your input, retrieving the official documents, and optionally adding searchable OCR text layers for fast review and easy local archiving.
Who It’s For
PatPDFs was designed for:
- Patent professionals — attorneys, agents, and paralegals handling Office actions or IDS filings.
- Researchers and analysts — anyone building datasets, citation maps, or prior art collections.
- Inventors and startups — teams exploring the patent landscape before filing.
Our goal is simple: to make public patent data truly usable.
The USPTO makes the information available — we just help you get it faster, cleaner, and in bulk.
