Patent Touch is presented as a free, AI-powered patent summary generator and search tool designed to make dense patent documents quickly understandable. Users can enter a patent number or publication number and receive an automatic summary in either short or long format. Outputs are available in multiple languages (JP, EN, CN). The interface emphasizes rapid first-pass understanding rather than exhaustive legal analysis and targets inventors, researchers, startup teams, and IP professionals who need to screen patents, extract the core idea, identify key claims and embodiments, and produce readable digests for business or technical review. The site notes that publicly visible content is limited, so practical details such as PDF upload, claim-mapping, or export formats are not confirmed. A pricing page exists but lists no paid plans; the tool is advertised as free. The footer mentions Seiji Tanaka in copyright. As with any automated summarizer, outputs are useful as a screening aid but should not replace careful legal review for decisive claim scope or status. Users uploading confidential documents should review data-handling policies.
