Design Patent Attorney
For products where appearance is part of the value, design patent protection can be an important part of an overall intellectual property strategy. Black Dog Law helps inventors, product companies, startups, and established businesses evaluate and pursue U.S. design patent protection for ornamental product designs.
Our office is in Tulsa, Oklahoma, but design patent rights are federal in scope. We represent clients before the United States Patent and Trademark Office (USPTO) and help coordinate design protection with broader patent, trademark, and product-launch strategy.
What Does a Design Patent Protect?
A design patent protects the ornamental appearance of an article of manufacture. It does not protect how the product works. Instead, the protection is directed to the visual design shown in the patent drawings, including shape, configuration, surface ornamentation, or a combination of those features.
That distinction makes the drawings especially important. In a design patent application, the drawings define the claimed design to a much greater degree than they do in a typical utility patent application.
Design Patent vs. Utility Patent
A utility patent generally protects functional features, methods, systems, or structures. A design patent protects ornamental appearance. Some products may justify one type of protection, while others may benefit from both.
For example, a product may have a new functional mechanism that supports utility patent protection and a distinctive exterior design that may separately support a design patent filing. The right strategy depends on what is new, what competitors are likely to copy, and what aspects of the product create commercial value.

When Design Patent Protection Can Be Valuable
Design patents are often worth considering when the visual appearance of a product is important to customer recognition or purchasing decisions. Common examples include:
- consumer products and product housings;
- furniture and home goods;
- tools and equipment with distinctive visual configurations;
- medical devices and product components;
- packaging and containers;
- wearable products and accessories;
- graphical user interface elements and icons, where eligible; and
- products with a distinctive combination of shape and surface ornamentation.
A design filing can also complement trademark or trade dress strategy when a product's appearance is part of its brand identity, although those rights arise under different legal standards and should be evaluated separately.
Why the Drawings Matter
Design patent drawings are not just illustrations. They define what is being claimed. Decisions about which portions are shown in solid lines, which are disclaimed with broken lines, what views are included, and how the article is presented can materially affect the scope of protection.
We work with clients and patent illustrators to develop drawing sets that accurately reflect the design while preserving appropriate claim scope. Small inconsistencies between views can create examination problems, so careful preparation matters.
Filing Before Public Disclosure
Timing is important. Ideally, design patent strategy should be considered before public launch, sale, crowdfunding, trade-show display, publication, or other disclosure of the product. Early filing can preserve options and reduce the risk that a disclosure affects patent rights in the United States or abroad.
If a design has already been disclosed, it is still worth discussing the timing and circumstances promptly because available rights can depend on the details.
Multiple Designs and Product Variations
A single product line may include several commercially important variations. Depending on how the designs relate to one another, separate applications or coordinated filings may be appropriate.
We help clients identify which visual features are worth protecting, whether multiple embodiments should be pursued, and how design filings fit into the broader product and patent portfolio.
USPTO Examination and Design Patent Prosecution
Design patent applications are examined by the USPTO. An examiner may raise issues involving the drawings, the claimed design, prior art, or formal requirements.
If an Office Action is issued, we evaluate the examiner's position, the cited references, and the available response strategy. That may involve amendments to the drawings or description, legal argument, or other prosecution steps depending on the issue.
Design Patents and International Protection
For products expected to be sold internationally, design protection should be considered early because foreign filing rights can be sensitive to timing and prior disclosure. International design strategy may involve direct national filings or other filing systems depending on the markets that matter to the business.
We help clients coordinate U.S. design patent strategy with foreign counsel when international protection is part of the plan.

Design Patent FAQs
What is the difference between a design patent and a utility patent?
A design patent protects ornamental appearance. A utility patent protects functional inventions, such as processes, machines, systems, or functional improvements. Some products may qualify for both.
How long does a U.S. design patent last?
For design patents issuing from applications filed on or after May 13, 2015, the term is generally 15 years from the date the patent is granted, subject to applicable law and circumstances.
Do design patents have maintenance fees?
No. U.S. design patents do not require periodic maintenance fees after issuance.
Can I patent a product shape?
Potentially, if the claimed shape is ornamental and meets the applicable patentability requirements. Functional aspects are not protected by design patent rights merely because they appear in the drawings.
Can I protect only part of a product?
In some cases, yes. Broken-line treatment can be used to disclaim portions of an article and focus the claim on selected ornamental features, but the drawing strategy needs to be considered carefully.
Can a design patent and trademark protect the same product appearance?
Potentially, but they protect different rights under different standards. Design patent rights are time-limited patent rights, while trade dress protection depends on trademark principles such as distinctiveness, nonfunctionality, and source identification.

If your product has a distinctive appearance that competitors could copy, it may be worth evaluating design patent protection before launch. Contact Black Dog Law or schedule a call to discuss the product, timing, drawings, and how design protection fits into the broader IP strategy.
