Description
PatentPilot is a patent drafting tool that guides inventions from disclosure to USPTO-ready filing. Built with Claude Code (Opus 4.6) and using parallel worktree agents, it runs on Next.js 14. The app features 8 interactive views and 11 Claude API endpoints.
Start by uploading a disclosure PDF, then find prior art on a similarity map, choose a claim strategy with risk analysis, and draft specs with highlighted new elements and prior art references. Generate patent claims with AI suggestions and confidence scores. Convert sketches into numbered figures. An AI examiner flags §101, §112, and consistency issues and offers one-click fixes. Export documents in USPTO format. The streaming chat lets users get real-time, tailored answers about patent prosecution from Claude Sonnet. Sonnet handles analysis; Haiku supports quick tasks. Demo mode gives instant feature walkthroughs.

# PatentPilot AI-powered patent drafting copilot that takes an invention from disclosure to USPTO-ready filing. Built with Claude Code (Opus 4.6) using parallel worktree agents.  ## What it does Upload a disclosure PDF and PatentPilot handles the rest: discover prior art plotted on a similarity landscape, select a claim strategy with risk analysis, draft specification sections with novel-element highlighting, generate patent claims with confidence scoring, formalize sketches into patent figures, run an AI examiner that surfaces legal issues with one-click fixes, and export USPTO-formatted documents. ## Setup Add your API keys to `.env.local`: ``` ANTHROPIC_API_KEY=your_key_here BRAINTRUST_API_KEY=your_key_here ``` Install dependencies and run: ```bash npm install npm run dev ``` Navigate to http://localhost:3000.
