# fto-triage Structured triage of blocking patents and draft claim charts before formal counsel review. Helps engineering and legal teams spot patent barriers before launch. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 619 installs · ★ 9795 - Author: anthropics · official Anthropic repository - License: Apache-2.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/anthropics/claude-for-legal/tree/HEAD/ip-legal/skills/fto-triage/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/fto-triage ## What it does The skill collects technical details and target jurisdictions to conduct a preliminary freedom-to-operate pass. If an external MCP connector like Solve Intelligence Patents is configured, it searches patent databases directly. Without a connector, it relies strictly on patents supplied by the user. For two to five plausible patents, the agent builds element-by-element claim charts against independent claims. Crucially, this skill never concludes a product is clear to launch. Under 35 U.S.C. § 284, patent infringement carries strict liability, and unaddressed knowledge can triple damages for willful infringement. The triage memo flags open issues for outside counsel, such as prosecution history, licensing availability, and IPR outcomes. If practice settings in `CLAUDE.md` are unconfigured, it routes to `/ip-legal:cold-start-interview` or requires running in generic provisional mode. Relying on this triage as a substitute for an attorney opinion is dangerous, because incomplete screening creates severe litigation exposure. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add anthropics/claude-for-legal --skill fto-triage -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/fto-triage/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/fto-triage/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add anthropics/claude-for-legal --skill fto-triage -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/fto-triage/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add anthropics/claude-for-legal --skill fto-triage -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/fto-triage/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install anthropics/claude-for-legal fto-triage ``` 2. **Manually: put the files in place** - File: `.github/skills/fto-triage/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add anthropics/claude-for-legal --skill fto-triage -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/anthropics/claude-for-legal --path ip-legal/skills/fto-triage ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/fto-triage/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add anthropics/claude-for-legal --skill fto-triage -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-for-legal/tree/HEAD/ip-legal/skills/fto-triage/SKILL.md ## When to use it - map product features against independent patent claims in a first-pass claim chart - flag doctrine-of-equivalents and divided infringement risks early - list open legal questions for outside patent counsel review - generate structured triage memos into the active matter folder ## Example prompts - /ip-legal:fto-triage "an on-device speech recognition model for consumer wearables, US launch first" - /ip-legal:fto-triage ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 386f9b58bba2e7d3 ````text --- name: fto-triage description: > Freedom-to-operate triage — a structured first look at potentially blocking patents, not an FTO opinion. Use when a product, process, or feature is being evaluated for blocking patents, when asked whether anything stops a launch, or to build a claim-chart first pass against the most plausible patents before patent counsel review. This skill never concludes a product is clear to launch. argument-hint: "[describe the product / process / feature and jurisdictions — or just the subject and I'll ask]" --- # /fto-triage **This is not a freedom-to-operate opinion.** A formal FTO opinion requires a comprehensive search, full claim construction, and element-by-element infringement analysis by registered patent counsel. Patent infringement is strict liability; willful infringement triples damages. A "no obvious blocking patents" result from this skill means the triage didn't find one — it does not mean the product is clear. ## Instructions 1. Read `~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md`. If it contains `[PLACEHOLDER]`, stop and direct to `/ip-legal:cold-start-interview`. 2. Follow the workflow below. 3. Run intake (product/process, technical detail, jurisdictions, known patents, timing). 4. Run a preliminary patent search if a connector is available (Solve Intelligence Patents, or other patent-research MCP). Otherwise say so in the output and proceed with the patents the user has supplied. 5. For the 2–5 most plausible patents, build a claim-chart first pass against each independent claim — element by element. Literal read first; flag doctrine-of-equivalents separately; flag indirect / divided infringement. 6. List open questions a real FTO study would resolve (enforceability, prosecution history, IPR outcomes, license availability, enforcement history of the assignee). 7. Write the triage memo to the matter folder or practice outputs folder. Apply the work-product header per role. 8. End with recommended next steps, a willfulness note (knowledge of specific patents factors into willfulness if the company proceeds without further counsel review), and the non-lawyer gate if the role is non-lawyer. This skill never concludes that a product is clear to launch. If uncertain, flag — patent counsel decides. ## Examples ``` /ip-legal:fto-triage "an on-device speech recognition model for consumer wearables, US launch first" ``` ``` /ip-legal:fto-triage ``` --- ## THIS IS NOT A FREEDOM-TO-OPERATE OPINION **The loudest guardrail in the plugin.
