Strategic drafting patterns and claim scope design guide for patent claims.

  • Tasks that involve Intellectual property
  • SKILL.md covers Drafting Patterns by Claim Type, Claim Scope Design Strategy, Terminology Rules and Rejection Response Patterns, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Claim Drafting Patterns is an agent skill from revfactory/harness-100. Strategic drafting patterns and claim scope design guide for patent claims. The 'claim-drafter' and 'patent-reviewer' agents must use this skill's drafting patterns, terminology rules, and dependent claim strategies when writing or verifying claims. Used for 'claim drafting', 'claim scope design', 'dependent claim strategy', etc. Note: Overall patent orchestration or prior art search is outside the scope of this skill.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Legal & Compliance, covering Intellectual property. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Intellectual property

Example prompts

  • “claim-drafter”
  • “patent-reviewer”
  • “claim drafting”
  • “/claim-drafting-patterns”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Claim Drafting Patterns loads about 1.2k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Claim Drafting Patterns — Claim Drafting Pattern Guide

Strategic composition, terminology selection, and claim scope optimization methodology for patent claims.

Drafting Patterns by Claim Type

Apparatus (Article) Claim Structure
In a [title of invention],
[Component A];
[Component B] connected to said [Component A] and performing [Function 1]; and
[Component C] receiving [data/signal] from said [Component B] and performing [Function 2],
comprising [title of invention].
Method (Process) Claim Structure
A method for [purpose], comprising:
(a) a step of [subject] performing [Action 1];
(b) a step of performing [Action 2] based on the result of step (a); and
(c) a step of performing [Action 3] according to [condition].
Computer Program Claim
A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
performing [Action 1];
performing [Action 2]; and
performing [Action 3].

Claim Scope Design Strategy

Hierarchical Claim Structure (Claim Tree)
Independent Claim 1 (Apparatus — broadest)
  +-- Dependent Claim 2: Component A elaboration
  +-- Dependent Claim 3: Component B elaboration
  +-- Dependent Claim 4: Connection method limitation
  +-- Dependent Claim 5: Additional Component D inclusion

Independent Claim 6 (Method — broadest)
  +-- Dependent Claim 7: Step subdivision
  +-- Dependent Claim 8: Condition addition
  +-- Dependent Claim 9: Additional step

Independent Claim 10 (Recording medium)
Scope Adjustment Techniques
TechniqueDescriptionExample
GeneralizationUse broader terms that encompass specific implementations"sensor" -> "detection means"
Functional ExpressionDefine by function instead of structure"means for storing data"
Open TransitionUse "comprising"Allows additional elements beyond those listed
Optional Limitation"Preferably" in dependent claimsMaintains independent claim scope
Numerical RangeBroad range -> Narrow range hierarchyIndependent "1-100", Dependent "10-50"

Terminology Rules

Expressions to Avoid
Prohibited ExpressionProblemAlternative
"about", "approximately"Scope unclear (description deficiency)Specify numerical range
"such as", "etc."Range unspecifiedSpecific enumeration or broader concept
"optimal", "superior"Subjective, no comparison basisPresent objective criteria
"conventional", "existing"Unclear time referenceSpecify particular technology
"as needed"Arbitrary compositionSpecify conditions
Antecedent Rules
First appearance: "a [component]" or "[component]"
Re-appearance: "said [component]" or "the [component]" (same term)

Violation example: "sensor" -> "said detector" (name mismatch = description deficiency)

Rejection Response Patterns

Novelty Rejection (Article 29, Paragraph 1)
Response strategy:
1. Identify differentiating elements from prior art
2. Add differentiating elements to independent claim (amendment)
3. Argue technical significance of differences in opinion statement
4. Merge dependent claims to narrow scope (fallback)
Inventive Step Rejection (Article 29, Paragraph 2)
Response strategy:
1. Argue lack of combination motivation: "There is no motivation to combine the prior art references"
2. Argue unexpected effects: "The combination produces synergistic effects"
3. Argue technical prejudice: "A direction a person skilled in the art would not attempt"
4. Commercial success evidence: "Market success demonstrates inventive step"

Claim Self-Check Checklist

  • Does the independent claim cover the broadest scope
  • Are all term antecedents clear
  • Is the transition phrase open-ended ("comprising")
  • Do dependent claims progressively narrow the scope
  • Is there a 3-type claim set (apparatus + method + recording medium)
  • Are all specification embodiments covered by claims
  • Do reference numerals match specification and drawings

Notes

  • Based on Patent Act and examination guidelines
  • Detailed drafting examples: See references/claim-examples.md
