patent-search

patent-search is a skill for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 37 tokens per session (577 once invoked), scanned A, original, MIT.

A connection to patent-search tools that search more than 100 million patent records through BigQuery, Google's service for querying large datasets.

In plain words
What is it for?
Use it to search patents by keywords or CPC and IPC classifications, retrieve full U.S. patent records, find related publications across countries, and check BigQuery access and quotas.
Why use it?
It removes the need to write separate search scripts and makes it easier to investigate prior art across patent text, classifications, and related family records.

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

patent-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.

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.

Patent Search Skill

This skill points Claude at the BigQuery patent-search tools registered by the patent-creator MCP server. Call the tools directly; do not shell out to Python.

When to use

  • Find prior art by keyword, classification, or family.
  • Pull full patent records (title, abstract, claims, description) for US patents.
  • Cross-reference an EP/WO patent into its US family member to get full text.

Available MCP tools

Tool What it does
search_patents_bigquery Keyword search across abstract / title / claims (US only for claims).
get_patent_bigquery Full patent details by publication number.
search_patents_by_cpc_bigquery Search by CPC classification prefix.
search_patents_by_ipc_bigquery Search by IPC classification prefix (good for older or non-US patents).
search_patent_family_bigquery All publications sharing a family ID across jurisdictions.
check_bigquery_status Verify auth and quota project before a long workflow.

Cost notes

BigQuery on-demand pricing is $6.25 / TiB (1 TiB free per month). The MCP server enforces a per-query bytes-billed ceiling, defaulting to 350 GiB. Override via PATENT_BIGQUERY_MAX_BYTES_BILLED if you need a larger scan window.

Choosing keywords

  • 2-3 keywords work better than long phrases (BigQuery LIKE matching is literal).
  • For non-US patents, claims is empty in the dataset; the MCP keyword tool already searches title/abstract for those jurisdictions. For full text on EP/WO, use the EPO OPS tools instead.
  • Use search_patent_family_bigquery to bridge from an EP/WO hit to its US family member when you need claims.

Common workflows

Prior art sweep:

  1. search_patents_bigquery(query=…, country="US") — broad scan.
  2. Pick the top hits' CPC codes from get_patent_bigquery.
  3. search_patents_by_cpc_bigquery(cpc_code=…) — pull adjacent technology.

Cross-jurisdiction lookup:

  1. search_patents_bigquery(query=…, country="EP").
  2. For any EP hit, get_patent_bigquery to get its family_id.
  3. search_patent_family_bigquery(family_id=…) to find the US member with full claims.
