You are an expert US patent attorney specializing in design patent applications under 35 U.S.C. § 171. Your task is to write a complete, legally compliant design patent description for the following design. DESIGN SUBJECT MATTER: [DESIGN_SUBJECT_MATTER] BRIEF DESCRIPTION OF THE DESIGN: [BRIEF_DESCRIPTION] FIGURE DESCRIPTIONS (list what each figure shows): [FIGURE_DESCRIPTIONS] KEY ORNAMENTAL FEATURES (distinctive visual elements): [KEY_FEATURES] INTENDED USE/ENVIRONMENT: [INTENDED_USE] PRIOR ART DISTINCTIONS (how this differs from common designs): [PRIOR_ART_DISTINCTIONS] STRUCTURE YOUR RESPONSE AS FOLLOWS: 1. TITLE: Create a concise, descriptive title per 37 CFR 1.153 2. CROSS-REFERENCE TO RELATED APPLICATIONS: [If applicable, or state "None"] 3. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH: [If applicable, or state "None"] 4. DESIGN PATENT DESCRIPTION (formal section): - Opening paragraph identifying the article and its use - Detailed description of the ornamental appearance - Description of each figure's view - Consistency statement regarding broken lines (if used) - Environment/context description (if applicable) 5. CLAIM: Draft the single design claim per 37 CFR 1.153: "The ornamental design for [article] as shown and described." 6. FIGURE DESCRIPTIONS TABLE: Formal listing matching USPTO requirements LEGAL COMPLIANCE CHECKLIST - VERIFY: - Description focuses on ORNAMENTAL characteristics, not functional - No structural/mechanical function described - Consistent terminology throughout - Proper broken line usage explained (if phantom/environment shown) - Single claim only - No "means for" or functional claim language Write in formal, precise patent prose. Avoid marketing language. Ensure the description would survive USPTO examination under 35 U.S.C. § 171 and 37 CFR Part 1, Subpart B.

Frequently Asked Questions

Can this prompt generate a complete, filing-ready design patent application?

No. This prompt generates a strong first draft of the formal description and claim, but a complete application requires: (1) properly formatted drawings/figures meeting USPTO standards, (2) a signed inventor's oath or declaration, (3) filing fees, and (4) attorney review of patentability and infringement issues. Use this prompt to reduce attorney drafting time, not eliminate professional legal services.

What's the difference between a design patent and a utility patent description?

Design patents protect ornamental appearance only (35 U.S.C. § 171); utility patents protect functional inventions (35 U.S.C. § 101). Design descriptions focus exclusively on visual characteristics—shapes, patterns, contours, surface ornamentation. They must NOT describe how the article works, its materials, manufacturing methods, or functional advantages. The single design claim covers the appearance 'as shown and described.'

How do I handle broken lines in design patent figures?

Broken lines (dashed/dotted) serve two purposes: (1) showing environmental structure that is not part of the claimed design (e.g., a phone in a case design), or (2) illustrating unclaimed boundaries for understanding. In your prompt input, explicitly state which elements should be broken lines and their purpose. The AI will include required consistency statements like 'The broken line showing of [element] is for illustrative purposes only and forms no part of the claimed design.'

Can I use this for international design patent applications?

This prompt is optimized for U.S. design patents under 35 U.S.C. § 171 and 37 CFR. International design protection varies: (1) Hague System applications have different description requirements—some jurisdictions require minimal or no description; (2) EU Registered Community Designs focus on visual representation with optional brief description; (3) China requires brief description but with specific content rules. For international filings, consult local counsel and modify the prompt variables accordingly.
