Patentability search reports
In the drafting app, an AI agent searches the USPTO, EPO and IP India in parallel, pulls out the key technical features of your invention and scores each patent it finds against them. You pick the relevant documents and get an editable report to export as .docx. A report costs 3 credits and is included in the 7-day free trial. Then draft the application from the same disclosure.
Filing in the US or Europe next? Our guides cover the US provisional application and the European patent application, with deadlines and official fees.
