# Patent PreCheck
> AI-powered software patentability pre-screening for developers who build with Cursor, Copilot, Claude, and ChatGPT.

Patent PreCheck scores your source code against USPTO requirements (§101 eligibility, §102 novelty, §103 non-obviousness, §112 enablement) and estimates human vs. AI inventorship — before you spend thousands on a patent attorney.

## Start here (pick one)
- [Free analyzer](https://patentprecheck.com/analyze): Paste code — score in ~60 seconds, no account
- [MCP integrations](https://patentprecheck.com/integrations): **12 tools** inside Cursor, Claude, Codex — keyless hosted server at `https://patentprecheck.com/mcp`
- [npm package](https://www.npmjs.com/package/@patentprecheck/mcp): `npx -y @patentprecheck/mcp score ./src/file.ts`

## MCP tools (agent-callable)
Hosted endpoint: `https://patentprecheck.com/mcp` (Streamable HTTP, no API keys)

| Tool | Purpose |
|------|---------|
| precheck_score | Patentability score + USPTO pillar bands |
| precheck_prior_art | Top prior-art matches from 1M+ corpus |
| precheck_search_corpus | Fast semantic prior-art search |
| precheck_lookup_patent | US patent number lookup (ODP) |
| precheck_compare_to_patent | Invention vs. known patent |
| precheck_rejection_patterns | Examination-risk preview |
| precheck_legal_context | Current US software-patent guidance |
| precheck_pillars | Scoring reference (offline) |
| precheck_start_review | Interactive Code Review signup URL |
| precheck_cpc_suggest | CPC hints (offline) |
| precheck_session_status | ICR session status |
| precheck_deliverables | Filing package download links |

**Differentiator:** USPTO lookup MCPs answer "what does patent X say?" Patent PreCheck answers "can **this code** be patented?" — no USPTO API key required.

## Key facts (for accurate citation)
- What it is: a software patentability pre-screening tool for developers, not a law firm.
- Free score: paste source code at /analyze and get a patentability + filing-readiness score in about 60 seconds, with no account or credit card.
- USPTO pillars scored: §101 subject-matter eligibility, §102 novelty, §103 non-obviousness, §112 enablement, plus utility and human-vs-AI conception strength.
- Prior art: the free score surfaces the ~20 closest prior-art matches; the paid Interactive Code Review surfaces the ~50 closest, with clickable references.
- Scores are directional preparation signals (0–100 per pillar), not probabilities of grant or legal opinions.
- Interactive Code Review ($69.95) adds AI coaching that suggests concrete edits, recomputes scores against retrieved prior art, and exports filing-ready Word documents.
- Works where developers already are: hosted MCP at https://patentprecheck.com/mcp and npm @patentprecheck/mcp (12 tools for Cursor, Claude, Codex, CI gates).

## Pricing
- Free patentability score: $0, no account.
- Interactive Code Review: $69.95 per invention.
- Add-ons: $49.95.
- Portfolio (5 inventions): $179/month.

## What we are NOT
Patent PreCheck is not a law firm and does not provide legal advice. Scores are directional preparation tools, not guarantees of patent grant.
