The Difference Between Designs and Patents

Design registration and patents are often confused. Both are official rights used to protect a product, but what each one protects is quite different. A patent protects the technical solution of an invention: how a product works and how it solves a problem. Design registration protects the appearance of a product.

The main differences, in general terms, are these:

• Subject matter: patents cover technical solutions and functioning; designs cover appearance and shape.
• Term: a patent runs for 20 years from the filing date; a design registration runs for 5 years, extendable in five-year periods up to a maximum of 25 years.
• Novelty: both require novelty; a patent also requires an inventive step, while a design is assessed on the distinct impression it makes on the informed user.
• Scope: a patent can be used against a competitor who achieves the same solution with a different look; a design focuses on similarity of appearance.

Software and computer programs. Computer programs are not regarded as inventions as such and are excluded from patent protection. However, applications that produce a technical effect may be assessed if they meet the legal requirements. The screen display of an application may be considered for protection as a design. Because this distinction depends on the file, expert advice is important.

Which one should you choose? If the main value of a product comes from a technical solution, a patent search should take priority. If success depends on appearance, shape or aesthetics, design registration may be more suitable. For many products, both protections are considered together: a patent for the technical solution and a design registration for the appearance.

Points to watch. For both patent and design filings, it is important to file before the product is made public, since public disclosure can affect the novelty assessment. The priority periods set by law also differ: 12 months for patents and 6 months for designs. These periods should be considered when planning foreign filings after the first application.

Understanding the boundaries of protection. The limits of patent and design protection are drawn differently. A product's way of working is assessed under patent protection, while its appearance is assessed under design protection. That the same product can be the subject of both shows that the two areas do not exclude each other, but which element belongs to which protection should be separated carefully before filing.

For a decision meeting, prepare two working documents rather than relying on one product photograph. Describe the visual differences in one and the technical problem addressed in the other. A storage container’s surface pattern belongs in the first; the operation of its closing mechanism belongs in the second. Ask the development team to record which changes influence customer preference and which improve performance. This reduces conflicting expectations. Checking that drawings and descriptions refer to the same product version also helps keep the teams aligned when preparing applications.

Conclusion. Patents and design registration do not have to be alternatives to each other. The right choice depends on which aspect of the product is valuable and what competitors could copy.
