Design patent or utility patent?

One of the most common questions new business owners ask is whether they should pursue a design patent or a utility patent. While every invention is different, there are some guiding principles under Philippine patent law that can help you decide.

Step 1: Understand the Basics

Utility Patent

A utility patent under the Intellectual Property Code of the Philippines protects the functional aspects of your invention. This covers how something works, operates, or is made.

Examples of what may qualify:

• A new machine or device that improves efficiency in manufacturing.
• A pharmaceutical formulation with unique therapeutic benefits.
• A software-enabled process that enhances logistics or financial transactions.
• A hybrid product combining hardware and software for smarter performance.

Utility patents generally provide 20 years of protection, counted from the filing date, subject to annual maintenance fees.

Industrial Design (Philippine Equivalent of “Design Patent”)

In the Philippines, there is no “design patent” in the U.S. sense. Instead, protection is granted through industrial design registration with the IPOPHL. This safeguards the ornamental or aesthetic appearance of a product, not its function.

Examples of what may qualify:

• The unique shape of a perfume bottle.
• A visually striking children’s toy.
• A graphical user interface (GUI) with a distinctive look.
• The ornamental pattern on fabric or packaging.

Industrial design protection lasts 5 years from the filing date, renewable up to a maximum of 25 years.

Step 2: Ask Yourself the Key Question

Are your invention’s unique aspects primarily functional or visual?

• If the functionality of your invention is what sets it apart → Utility Patent.
• If the appearance is its main selling point → Industrial Design Registration.
• If both functionality and aesthetics are unique → Consider filing for both.

Step 3: Avoid Common Mistakes

Mistake 1: Believing an Industrial Design Protects Function

A frequent error is assuming that registering an industrial design will protect the product as a whole. In reality, it only covers the visual design, leaving the functional features vulnerable.

For example, in Pearl & Dean (Philippines), Inc. v. Shoemart, Inc., the Supreme Court emphasized that aesthetic elements do not extend protection to functional innovations, which must instead be patented as inventions.

Mistake 2: Ignoring Industrial Design Protection

On the other hand, some inventors overlook industrial design filings, thinking only the utility patent matters. This is risky—competitors may copy your product’s look and feel while avoiding infringement on functional claims.

Design registrations are also faster and cheaper to obtain, making them a practical tool to fight knock-offs on e-commerce platforms while waiting for your patent application to be granted.

Mistake 3: Waiting Too Long to File

In the Philippines, patents and industrial designs follow the “first-to-file” rule. Delaying your application risks losing your rights entirely if someone else files before you. Unlike the U.S., the Philippines does not provide a broad one-year grace period—though there are limited disclosures exempted (such as those made at recognized exhibitions or against an abusive third party).

Real-World Examples in the Philippines

1. Utility Patent Example:
   A Filipino startup developed a solar-powered water filtration device aimed at rural communities. Its novelty was in the filtration process and energy efficiency, so a utility patent was granted to cover the technology.
2. Industrial Design Example:
   A local toy company registered the distinct shape of its educational building blocks as an industrial design. Even though the blocks themselves were simple, their unique appearance provided commercial distinction in the market.
3. Both Utility & Design Protection:
   In the electronics sector, a company developing durable yet stylish mobile phone casings filed both:
   • Utility patent for the shock-absorption technology.
   • Industrial design for the casing’s stylish contours and colors.

Copyright Overlap

Sometimes, copyright law can also apply—especially for graphical works, software code, or decorative artworks applied to functional products. For example, a unique textile pattern may be protected both as a copyrightable artistic work and as an industrial design. However, copyright in applied art is often limited, so combining it with design registration gives stronger commercial protection.

Practical Tip for Entrepreneurs

If you are still raising funds and want to keep your options open, you may consider filing a provisional patent application with the IPOPHL. This gives you 12 months to refine your invention and secure financing before converting to a full utility patent.

✅ Bottom line:

• File a utility patent if your innovation is about how it works.
• File an industrial design if it’s about how it looks.
• File both if your product is unique in both aspects.
• Don’t wait—file early to secure rights.
