Design Patents vs. Utility Patents: What You Need to Know
Share:
Understanding how to differentiate between a design and a utility patent is critical for innovators and companies wishing to protect their intellectual property. Both patents have distinct legal protections that target specific product, process, or method aspects.
Note: Before we get into the specifics of both, please note that utility patents are different from utility models (which usually have not more than 10 years of coverage and are also called innovation or petty patents in some countries). This article talks about utility patents and not models.
Understanding the Basics
What is a Design Patent?
Design patents are used to protect the visual and ornamental aspects of a product. They focus on the aesthetics of an invention, like its design, shape, surface decor, or configuration. Design patents help protect a brand’s visual identity. Automotive, fashion, and electronics are some of the key industries in which design patents are mostly filed. There are iconic examples, such as Coca-Cola’s bottle shape or the Apple iPhone design.

What is a Utility Patent?
Utility Patents protect the invention’s operational and functional features. They protect the development of new processes, machines, or materials that serve specific tasks. These patents require a thorough search to assess existing functional patents and evaluate the patent database for potential conflicts.
Utility patents are particularly important for companies operating in the manufacturing, pharmaceuticals, and technology sectors, where the ability to innovate in product function is a crucial driver of the market’s growth and success.
Key Differences between Design and Utility Patents
When deciding between utility and design patents, it is important to understand the fundamental differences between the two in order to opt for the right protection for an invention. Here are the critical differences between design and utility patents:
Legal Scope and Protection
Design patents protect the exclusive rights of an inventor when it comes to the visual appearance of a product. On the other hand, utility patents protect the functional aspects of a product.
For example, a company could patent the design of an exclusive chair (its form, lines, and surface characteristics) and the unique mechanism that lets it fold or rotate. In this instance, the design patent would protect the chair’s aesthetics, while the utility patent would ensure its functionality.
For companies aiming to protect both the appearance and functionality of their products, employing both patents and utilizing AI Industrial Design tools for Patent Analysis is a wise choice.
Application Process
Design patents are comparatively more straightforward and quicker to submit. They require applicants to submit thorough sketches of the design’s aesthetic aspects. After being approved, they are typically granted between 12 and 18 months. Their validity can last for up to 15 years.
Utility patents, however, require more detailed documentation. The inventor must be able to provide a full explanation of how the invention is unique and how it operates, along with its technical characteristics, advantages, and specific procedures. Examining the invention is lengthy and takes a few years. The patent remains in force for a longer duration, i.e., for a maximum of 20 years, subject to payment of a maintenance fee.
With the help of AI Industrial Design Search, the process of filing for either type of patent becomes smoother, allowing for a more efficient Patent Analysis to assess existing patents and refine an application strategy.
Strategic Considerations
The decision of whether to file a utility or design patent or both requires a thorough evaluation of your invention’s features and your long-term objectives. Additionally, utilizing search databases, such as patent databases and industrial design databases, and employing AI tools can help give you an idea of the existing prior art and thereby help refine your protection strategy.
Here are some key strategic considerations:
- When to Consider a Design Patent
Design patents are perfect for products whose value is determined by their appearance, not their purpose. This is typical for products where aesthetics heavily influences consumers’ preferences, like clothing, electronics, and home décor.
Businesses that want to differentiate their products from the crowd by using unique designs frequently depend on patents to prevent competitors from copying their design characteristics.
However, there are some limitations. A design patent only protects the visual elements captured in the patent’s illustrations. Any slight changes made by competitors may help them evade the security provided by the patent. Patent Analysis through AI-driven Industrial Design Search tools can help identify these potential loopholes early.
- When to Consider a Utility Patent
Utility patents must be considered if an invention has a new function or process. For instance, if you have created a brand-new engine design that improves fuel efficiency or an instrument for medical use that provides advanced diagnostic capabilities, a utility patent could be the best option to protect these functional advances.
Utility patents provide greater protection since they encompass the fundamental functions of an invention regardless of its appearance.
However, patents for utility purposes are more costly and take longer to obtain because of the complexity of the application process and the maintenance charges for the patent’s validity.
- Combining Both for Maximum Protection
Combining design and utility patents often provides comprehensive protection, especially for products with both functional and distinctive visual elements. For instance, while the ‘touchscreen technology’ of an iPhone is protected by its utility patents, its distinctive rounded corners and edge-to-edge display are protected by design patents.
Similarly, Dyson demonstrates the value of this dual approach, holding both utility and design patents for its vacuum cleaners. The utility patent covers its unique cyclone technology, while the design patent protects elements like the vacuum’s handle shape and the arrangement of its cyclones.
Summing up
Choosing the right type of patent, or combining both utility and design patents, is essential to protect your invention and broaden its potential. By carefully considering the unique features of your creation and carrying out detailed patent research, you can procure the strongest possible protection for your intellectual property. This strategic approach not only protects your innovation but also adds to your brand and builds up your competitive edge in the marketplace. Remember, securing the right patent is a key step in transforming your inventive ideas into a successful reality.
