The U.S. market is one of the largest consumer goods markets in the world and one of the most competitive. As soon as a new product is released every day, the products that mimic it also appear quickly. Especially in the field where appearance design such as fashion, home appliances, interior goods, household goods, and IT accessories are at the core of competitiveness, ‘Who got the rights first’ becomes an important factor in the success of the business.
The U.S. Design Patent (US Design Patent) is the exclusive protection of the appearance of these products, and the rights are retained for 15 years from the date of registration. There is no maintenance fee, so once you register, you can have a relatively stable long-term protection.
Errors in drawings, filing timing, or prior-design review can lead to refusal or limit protection. Seeking protection after disclosure can create additional difficulties.
In this article, we summarize the main things you should know about applying for a U.S. design patent in Q&A format.
What is an American design patent?
The U.S. design patent protects the visual appearance of products. The object of protection is the ‘visible form’ itself, which the consumer perceives as the entire shape of the product, the surface decoration, or the combination thereof.
For example, the curved shape of a chair, the placement of buttons in an electronic device, and the surface pattern.
However, the functional element is not protective. The inevitable structure is excluded to perform certain functions, and only decorative and aesthetic elements are protected.
What is the difference between a patent and a design patent?
Patent (Utility Patent) is a system that protects technical elements such as the function, structure, and working principle of the invention.
On the other hand, the design patent protects the visual elements of the product, such as shape, contour, and decoration.
In summary,
- Patent: How it works.
- Design patent: what it looks like
Each protects a different aspect of the product.
What is the scope and duration of the U.S. design patent?
Once registered, you can exercise your exclusive rights for 15 years, during which time you will be able to respond to infringements against the same or similar designs. In addition, there are no maintenance costs, so you can maintain your rights at no additional cost.
What documents are required for the application?
U.S. design patent applications are centered around the following documents:
- Drawing: The most important factor, determining the scope of the right
- patent specification (Specification): A brief description of the drawing
- Oath/Declaration: The Creator's Verification Document
- Information Disclosure Statement (IDS): Disclosure of relevant known prior art
In particular, the completion of the drawing is most important because it depends on the registration and scope of the rights.
How should I prepare my drawings?
Drawings are a key factor in determining the scope of rights.
Provide sufficient views to show the design clearly, commonly including front, rear, left, right, top, and bottom views, with perspective or enlarged views where appropriate.
Also
- Use lines and surface shading to show the form clearly.
- Omit unnecessary background elements.
- Use broken lines appropriately for matter not claimed.
Consistent presentation is important.
Since the elements not represented in the drawing cannot be protected, it is necessary to prepare strategically in the initial design phase.
Can I submit color drawings?
Possibly, but it needs attention. When you submit a color drawing, the color itself is included in the scope of the right.
Therefore, if color is not the key element, then black-and-white drawings are usually more advantageous.
How does the application process work?
The U.S. design patent is prepared → filed → reviewed → registered.
Preparing the drawings
Preparing compliant drawings is a key part of a design patent application. Provide the patent firm with the product, suitable photographs, or CAD data so that the design can be depicted accurately. The time required depends on complexity and revisions.
The patent specification
The specification includes the design title, descriptions of the views, and the required design claim. It focuses on the ornamental design rather than a technical description of function.
USPTO Patent Center
Prepare all documents and submit them online through the U.S. patent application system. At this stage, the filing fee will be paid, depending on whether you are a small entity or a micro-entity.
Examination process
Examination timing varies with the USPTO's workload and any objections raised. The former 'Rocket Docket' expedited design examination procedure was suspended on 17 April 2025 and subsequently eliminated; it should not be presented as an available filing option.
Registration
If the application meets the requirements, the USPTO issues a Notice of Allowance. After payment of the issue fee, the design patent is granted. For current applications, the term is 15 years from grant, with no periodic maintenance fees.
Practically, the initial preparation step is important, as the request for correction of the drawing and the rejection of the prior design are the main variables.
What are the frequent mistakes?
A typical mistake is as follows.
- Required drawings missing → Reduced scope of rights
- Filing outside an applicable grace period after disclosure may bar protection.
- Unnecessary color drawings → Limit the scope of rights
These factors are difficult to follow up, so a thorough review is required in the pre-application phase.
Can I file an application with South Korea and the US?
It is possible. Filing in the United States within six months of a Korean filing allows a claim to the Korean filing date under the Paris Convention priority system.
The U.S. design patent is a relatively simple process that allows for long-term rights. However, the strength of the right varies greatly depending on the completion of the drawing and the application. Therefore, it is important to prepare strategically with experts from the very beginning.
