PatentAssist.ai is an AI workspace for patent drafting and prior art search, built for patent attorneys, patent agents, IP law firms, in-house IP teams and inventors.

Start from an invention disclosure and PatentAssist.ai drafts claims first, so you can review and edit them before it writes the complete or provisional specification, abstract and figure descriptions. Drafts follow the format of the patent office you file with: USPTO, EPO, DPMA (German) or IP India. It also generates patent drawings such as flowcharts, block diagrams and sectional views from the specification.

Prior art search is built in. The free search app at search.patentassist.ai covers 20M+ US, European and Indian patents with AI semantic search and field search, and the drafting workspace can produce patentability search reports.

Built for confidential work: AI models run on Azure OpenAI in EU regions, customer data never trains AI models, and a GDPR data processing agreement and sub-processor list are published.

The app runs in English, German, Spanish and French. Plans start at $29/month with a 7-day free trial.
