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.
Strategic composition, terminology selection, and claim scope optimization methodology for patent claims.
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].
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].
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].
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)
| Technique | Description | Example |
|---|---|---|
| Generalization | Use broader terms that encompass specific implementations | "sensor" -> "detection means" |
| Functional Expression | Define by function instead of structure | "means for storing data" |
| Open Transition | Use "comprising" | Allows additional elements beyond those listed |
| Optional Limitation | "Preferably" in dependent claims | Maintains independent claim scope |
| Numerical Range | Broad range -> Narrow range hierarchy | Independent "1-100", Dependent "10-50" |
| Prohibited Expression | Problem | Alternative |
|---|---|---|
| "about", "approximately" | Scope unclear (description deficiency) | Specify numerical range |
| "such as", "etc." | Range unspecified | Specific enumeration or broader concept |
| "optimal", "superior" | Subjective, no comparison basis | Present objective criteria |
| "conventional", "existing" | Unclear time reference | Specify particular technology |
| "as needed" | Arbitrary composition | Specify conditions |
First appearance: "a [component]" or "[component]"
Re-appearance: "said [component]" or "the [component]" (same term)
Violation example: "sensor" -> "said detector" (name mismatch = description deficiency)
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)
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"
