# Prior Art Search Search patents and literature for prior art relevant to: **$ARGUMENTS** Adapted from `/research-lit` for patent-specific searching. ## Constants - `MAX_PATENT_RESULTS = 20` — Maximum patent documents to analyze in detail - `MAX_PAPER_RESULTS = 15` — Maximum academic papers to analyze in detail - `SEARCH_YEARS = 10` — How many years back to search - `PATENT_DATABASES = "google-patents, espacenet"` — Patent databases to search ## Inputs Read the invention description from: 1. `$ARGUMENTS` if it contains technical details 2. `patent/INVENTION_BRIEF.md` if it exists 3. `INVENTION_BRIEF.md` if it exists at project root ## Shared References Load `../shared-references/prior-art-databases.md` for search strategy templates and IPC/CPC classification guidance. ## Workflow ### Step 1: Extract Search Concepts From the invention description, identify: 1. **Core inventive concept**: The primary technical contribution (1-2 sentences) 2. **Technical problem**: What problem it solves 3. **Key technical features**: 4-6 specific technical elements that define the invention 4. **IPC/CPC classes**: Predict relevant classification codes (e.g., G06N, G06F) ### Step 2: Patent Search For

What does the prior-art-search skill do?
Search patent databases and academic literature for prior art relevant to an invention. Use when user says \"现有技术检索\", \"prior art search\", \"专利检索\", \"check patents\", or wants to find relevant prior art.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill prior-art-search --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
