review-epo-claims

review-epo-claims is a command for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 22 tokens per session (2,304 once invoked), scanned A, original, MIT.

A command that checks patent claims against European Patent Office rules on clear wording, concise claims, and support in the patent description. Patent claims define what legal protection an invention is seeking.

In plain words
What is it for?
Use it to review claim clarity, conciseness, description support, two-part claim structure, dependent-claim references, and claim categories under the European Patent Convention.
Why use it?
It helps reveal vague terms, unnecessary repetition, unsupported claim scope, and structural problems before filing or responding to an examination.

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

review-epo-claims 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.

EPO Claims Review

Automated analysis of patent claims for European Patent Office compliance with Art. 84 EPC / Rule 43 EPC / EPO Guidelines Part F.

Focus Area: $ARGUMENTS

What This Command Does

Performs comprehensive EPO claims analysis:

  1. Clarity Analysis (Art. 84 EPC):

    • Identifies unclear or ambiguous terms
    • Detects relative terms without reference points
    • Checks for consistent terminology throughout claims
    • Validates technical feature definitions
  2. Conciseness Check (Art. 84 EPC):

    • Detects redundant claims
    • Identifies unnecessarily complex claim structures
    • Checks for duplicate scope between claims
    • Validates claim set economy
  3. Support by Description (Art. 84 EPC):

    • Verifies all claimed features are disclosed in the description
    • Checks claim scope does not exceed disclosure
    • Validates generalizations from specific examples
    • Identifies unsupported claim breadth
  4. Claim Structure (Rule 43 EPC):

    • Validates two-part form (preamble + characterizing portion) where appropriate
    • Checks independent claim structure
    • Validates dependent claim references
    • Verifies claim categories (product, process, apparatus, use)
  5. Issue Categorization:

    • Critical: Will cause objection under Art. 84 EPC
    • Important: May cause objection or limit claim scope
    • Minor: Best practice improvements per EPO Guidelines

Who This Is For

  • Patent attorneys preparing EP applications
  • Applicants responding to EPO Art. 84 objections
  • Practitioners converting US claims to EPO format
  • Quality assurance before EP filing or Euro-PCT entry

Process

Step 1: Provide Claims

You can provide claims in three ways:

Option 1: Paste claims directly

/review-epo-claims

> Paste your claims text, then type 'END' on a new line:

1. A system for authenticating users, characterised in that
   the system comprises a distributed ledger configured to
   store and verify credentials.

2. The system according to claim 1, wherein the distributed
   ledger is a blockchain.
