prior-art-search

prior-art-search is a skill for Claude Code from Raw1mage/patentmcp. It costs 26 tokens per session (2,111 once invoked), scanned A, a copy of prior-art-search, MIT.

A structured workflow for searching existing patents, called prior art, to assess whether an invention may be patentable. It uses patent keywords, technical classifications, and patent records.

In plain words
What is it for?
Use it to define an invention, search patents, study patent timelines and landscapes, assess patentability, perform freedom-to-operate research, and prepare an Information Disclosure Statement for the USPTO.
Why use it?
It organizes a broad patent search so relevant earlier inventions and possible blocking patents are less likely to be missed. It also helps prepare information for a patent filing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prior-art-search scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (prior_art_types.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Prior Art Search Skill

Systematic 7-step methodology for comprehensive patent prior art searches and patentability assessments.

When to Use

Invoke this skill when users ask to:

  • Conduct prior art search for an invention
  • Assess patentability of an idea
  • Perform freedom-to-operate analysis
  • Find blocking patents
  • Research patent landscapes
  • Prepare for patent filing

What This Skill Does

Implements a professional 7-step prior art search methodology combining:

  • Keyword searches across 100M+ patents (BigQuery)
  • CPC classification searches
  • USPTO API searches
  • Timeline analysis
  • Patentability assessment
  • IDS (Information Disclosure Statement) preparation

The 7-Step Methodology

Step 1: Invention Definition (2-3 min)

Goal: Extract key features and define innovation scope

Process:

  1. Interview user about invention
  2. Extract core technical elements
  3. Identify novel features
  4. List all components/steps
  5. Define search scope

Output: Structured invention summary with key features

Questions to Ask:

  • What problem does this solve?
  • What are the key components/steps?
  • What makes this different from existing solutions?
  • What is the core innovation?

Step 2: Keyword Strategy (2-3 min)

Goal: Develop comprehensive search keyword list

Process:

  1. Primary keywords from invention
  2. Synonyms and variations
  3. Technical terminology
  4. Industry-specific terms
  5. Boolean search strings

Output: Keyword search strategy document

Example:

Primary: blockchain authentication
Synonyms: distributed ledger verification, cryptographic authentication
Technical: public key infrastructure, digital signature
Related: decentralized identity, trustless verification
Searches:
- "blockchain AND (authentication OR verification)"
- "(distributed ledger) AND (identity OR credential)"
- "cryptographic AND (login OR access control)"

Step 3: Broad Keyword Search (3-5 min)

Goal: Cast wide net to find relevant patents
