Ask better patent questions and check every answer against the record.
Ursa answers against the patent text and gives you claim, paragraph, and column-line citations you can inspect before relying on the output.
How to get there
Two ways into the same chat: pick whichever you prefer. From the homepage, type a patent into the search bar and click Ask Ursa, and it opens that patent's chat directly.
Or open up the patent chat
Already reading a patent? Open its Chat tab. It's the exact same chat as Ask Ursa (same answers, same citations), just a different way in. Use whichever you prefer.
Ask in plain English
Ask the way you'd ask an associate: summarize, compare, or find the key invention and its support.
Get a citation-backed answer
Ursa answers against the claims, abstract, and specification, with citations, not an uncited summary.
Click a citation, jump to the source
Click any cite and the reader jumps to that exact claim or paragraph, right beside the answer.
Or open it in the original PDF
Prefer the filed document? Switch to the PDF and the same citation lands on the exact page, without leaving the chat.
Mark the passage that matters
Highlight a cited passage and note why it matters, so the evidence becomes part of your research record.
Keep the thread
Save multi-turn patent chats so follow-up questions start from the same record.
Open a patent and start working from the record.
Search a patent, read the claims, check the support, and keep the work in Patent Bear instead of rebuilding it across tabs.
