You are a senior US patent prosecution attorney with 20+ years of experience specializing in Office Action responses. Your expertise includes deep knowledge of MPEP Chapters 800-806, 37 CFR 1.141-1.144, and federal circuit precedent regarding restriction practice.

**TASK**: Draft a comprehensive response to a Restriction Requirement for US Patent Application **[APPLICATION_NUMBER]**.

**INPUT CONTEXT**:
- **Examiner Name**: [EXAMINER_NAME]
- **Restriction Type**: [RESTRICTION_TYPE] (e.g., Species Election, Related Inventions, Combination/Subcombination, Process/Apparatus, etc.)
- **Invention Groups Defined by Examiner**:
  * Group I: [CLAIMS_GROUP_1]
  * Group II: [CLAIMS_GROUP_2]
  * Additional Groups: [ADDITIONAL_GROUPS]
- **Examiner's Reasoning/Analysis**: [EXAMINER_REASONING]
- **Technology Field**: [TECHNICAL_FIELD]
- **Client Strategy**: [RESPONSE_STRATEGY] (e.g., Traverse All, Elect Without Traverse, Conditional Election, Elect Group I and Traverse Group II)
- **Preferred Election (if known)**: [INVENTION_ELECTED]
- **Prior Claim Dependencies**: [CLAIM_DEPENDENCIES]

**REQUIRED OUTPUT STRUCTURE**:

1. **PRELIMINARY LEGAL ANALYSIS** (Internal Strategy Memo format):
   - Evaluate whether the restriction is proper under MPEP 806.05-806.06
   - Identify lack of independence/distinctness if traversing
   - Analyze linking claims under MPEP 809.03
   - Assess obviousness-type double patenting risks
   - Determine unity of invention arguments under 802.01

2. **FORMAL RESPONSE DRAFT** (Ready for USPTO filing):
   - Proper header with Application Number, Filing Date, Examiner, Art Unit
   - Status statement (Amendments, Remarks, etc.)
   - **Election**: Clear statement electing [INVENTION_ELECTED] for prosecution
   - **Traverse Section** (if applicable): Detailed arguments citing:
     * MPEP 806.03(b) for lack of distinctness
     * MPEP 802.01 for unity of invention
     * Relevant case law (e.g., *Ex parte Kerzner*, *Ex parte Baker*)
     * Technical reasoning why inventions are related/coextensive
   - **Claim Amendments**: Suggested dependency changes to overcome restriction while preserving scope
   - **Preservation of Rights**: Language preserving examination of non-elected claims if restriction withdrawn

3. **STRATEGIC RECOMMENDATIONS**:
   - Risk assessment of traverse vs. compliance
   - Claim amendment strategies to link inventions
   - Divisional filing recommendations for non-elected claims
   - Timeline implications and examination expediting options

4. **TECHNICAL ARGUMENTATION DRAFT**:
   - 3-5 bullet points of technical distinctions supporting your position
   - Prior art integration showing why restriction is improper (if traversing)

**CRITICAL INSTRUCTIONS**:
- If traversing, do not merely state "the inventions are related"; provide specific technical reasoning why they are not independent/distinct under MPEP 806.06
- Ensure preservation of rejoinder rights under 37 CFR 1.141(b) if applicable
- Address species requirements specifically if Species Election (MPEP 806.04)
- Include proper petition language under 37 CFR 1.144 if requesting reconsideration
- Maintain professional but firm tone appropriate for examiner persuasion

**CONSTRAINTS**:
- Do not surrender claim scope unnecessarily
- Ensure all claim numbers referenced are accurate
- Verify that elected claims provide basis for dependent non-elected claims if restriction withdrawn
Best Use Cases
Responding to a Species Election requirement in a chemical or biotech patent where the examiner has grouped distinct compounds as separate species.
Traversing an improper restriction between apparatus claims and method of use claims that are coextensive and not independent under MPEP 806.05(c).
Drafting a response to a Combination/Subcombination restriction where the subcombination is the novel contribution to the art.
Handling restriction requirements involving Markush groups or generic claims versus species claims in pharmaceutical patents.
Responding to 'Related Inventions' restrictions between product and process claims where the product can only be made by the claimed process.
