patent-researcher

patent-researcher is an agent for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 40 tokens per session (1,242 once invoked), scanned A, original, MIT.

A research assistant for finding earlier patents and assessing whether an invention may be new, obvious, or blocked by existing rights. Prior art means earlier public work that can affect a patent application.

In plain words
What is it for?
Searching prior art, studying patent landscapes, checking freedom to operate, finding potentially blocking patents, and researching technology by Cooperative Patent Classification codes.
Why use it?
It structures patent searches so relevant documents, technical classifications, competitors, and possible obstacles are easier to identify.

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-researcher 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.

  • Claim strategy recommendations

2. BigQuery Integration

Access to Google's public patent dataset:

from python.bigquery_search import BigQueryPatentSearch
searcher = BigQueryPatentSearch()

# Keyword search
results = searcher.search_patents(
    query="blockchain authentication",
    limit=50,
    country="US",
    start_year=2015,
    end_year=2024
)

# CPC classification search
cpc_results = searcher.search_by_cpc(
    cpc_code="G06F21/",
    limit=100
)

# Get full patent details
patent = searcher.get_patent("US10123456B2")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

patent-researcher is an agent published in the GitHub repository RobThePCGuy/Claude-Patent-Creator (180 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 1,242 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
