Why Design Patents Matter for eVTOL and Aerospace Equipment
The eVTOL (electric vertical takeoff and landing) aircraft industry is booming, with aerospace startups and major manufacturers racing to develop next-generation air mobility solutions. As competition intensifies, securing intellectual property (IP) protection becomes essential.
While utility patents protect functional aspects of an invention, design patents safeguard the aesthetic features and unique appearance of an aircraft or aviation equipment. For eVTOL manufacturers, protecting distinctive aircraft designs, cockpit layouts, and aerodynamically optimized shapes is crucial to prevent copycats and maintain market exclusivity.
In this guide, we’ll explore how design patents can protect eVTOL innovations and break down the application process, key requirements, and legal strategies.
What is a Design Patent for eVTOL?
A design patent is a form of intellectual property protection that covers the ornamental appearance of a product rather than its functional elements.
Key Elements of a Design Patent for eVTOL Equipment:
Shape and Configuration – The unique external contours of an aircraft
Surface Ornamentation – Decorative or aesthetic features
Non-Functional Elements – Aspects that do not affect performance, such as exterior aesthetics
For example, a distinctive fuselage shape, rotor blade design, or cockpit interface layout may qualify for design patent protection if it meets novelty requirements.
Real-World Example: Airbus has secured multiple design patents covering the futuristic aerodynamic shapes of its eVTOL aircraft, ensuring competitors cannot directly replicate these innovative designs.
How to Apply for a Design Patent for eVTOL and Equipment
To successfully obtain a design patent, companies must carefully prepare their applications and comply with USPTO guidelines.
Step 1: Conduct a Patent Search for Existing eVTOL Designs
Before applying, conduct a comprehensive patent search through:
- USPTO Design Patents Database
- WIPO Global Design Database
- Google Patents
This helps identify similar patented designs and ensures that your eVTOL design is novel and non-infringing.
Step 2: Prepare High-Quality Patent Drawings and Descriptions
The USPTO requires that all design patent applications include precise drawings. Unlike utility patents, which describe functional elements, design patents rely entirely on visual representation.
Guidelines for eVTOL Patent Drawings:
- Use professional patent illustrators for accuracy
- Include multiple views (front, side, top, bottom, perspective)
- Ensure consistency in shading and proportions
Common mistakes include submitting incomplete or inconsistent illustrations, which can delay approval or result in rejection.
Step 3: File the Design Patent Application with the USPTO
Once your patent drawings and descriptions are ready, submit the design patent application to the United States Patent and Trademark Office (USPTO).
Filing Options:
- Standard Design Patent Application (Regular processing takes 16–20 months)
- Rocket Docket Expedited Examination (Approval within 6–7 months)
For faster approval, companies should consider using Rocket Docket, an accelerated examination process designed for urgent IP protection.

Key Differences Between Utility and Design Patents for eVTOL Companies
It’s important to distinguish between design patents and utility patents, as both play different roles in aerospace IP protection.
| Feature | Utility Patent | Design Patent |
| Protects | Functional aspects of an invention | Ornamental/aesthetic features |
| Lifespan | 20 years from filing date | 15 years from grant date |
| Required Drawings | Complex technical schematics | High-quality, detailed illustrations |
| Common in eVTOL? | Protects propulsion, battery, software | Protects aircraft shape, cockpit layout |
For full aerospace IP protection, many eVTOL manufacturers apply for both types of patents.
Benefits of Design Patents for Aerospace and eVTOL Equipment
Why should eVTOL companies prioritize design patents?
Market Differentiation
A unique aircraft design can set your company apart and reinforce brand identity.
Exclusive Rights
Design patents provide 15 years of protection, preventing competitors from copying aircraft aesthetics.
Competitive Edge
Patent ownership can enhance company valuation, making it easier to attract investors and licensing opportunities.
Common Mistakes in eVTOL Design Patent Applications
Companies often make costly errors that lead to rejections or weak patents.
Mistake #1: Submitting Poor-Quality Drawings
Ensure clear, consistent, and detailed illustrations.
Mistake #2: Overlapping Claims with Utility Patents
Clearly define what elements are protected under design vs. utility patents.
Mistake #3: Failure to Enforce Patents Internationally
Expand protection through the Hague System for Industrial Designs to cover global markets.
Mistake #4: Delaying Patent Applications
Competitors can file first, jeopardizing your ability to protect key designs.
How to Expedite a Design Patent with Rocket Docket
For companies needing faster patent approval, Rocket Docket offers an expedited path.
Advantages of Rocket Docket:
