Continuing our 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐁𝐚𝐬𝐞 𝐏𝐚𝐭𝐞𝐧𝐭 𝐒𝐞𝐫𝐢𝐞𝐬, a practical guide for inventors, startups, and researchers to better understand patent protection in India.
It’s time to understand the difference between a utility patent and a design patent which is essential for any inventor/researcher seeking to protect an innovation. Choosing the appropriate type of patent determines the scope and strength of legal protection. In many jurisdictions, particularly in the United States, inventors may apply for either a utility patent or a design patent depending on whether they wish to safeguard the functional aspects of their invention or its ornamental appearance. While both types of patents grant exclusive rights, they differ significantly in terms of scope, application requirements, duration of protection, and overall cost.
Utility Patent
A utility patent protects the functional aspects of an invention: how it works, how it is used, and how it is made.
It covers:
- Processes or methods
- Machines/Devices
- Manufactured items
- Chemical compositions/Formulations
- Functional improvements to existing inventions
Example: If you invent a new type of engine that improves fuel efficiency, a utility patent would protect the mechanical system and operational method.
In India, such protection is granted under the Patents Act, 1970 and requires novelty, inventive step, and industrial applicability. A patent is granted for twenty years from the filing date and confers the right to exclude others from making, using, selling, or importing the invention without authorization.
Design Patent
A design patent protects the ornamental appearance or aesthetic features of a product: how it looks rather than how it works.
It covers:
- Shape
- Surface ornamentation
- Configuration
- Visual design of a product
Example: The distinctive curved shape of a smartphone may be protected by a design patent, even if the internal electronics are protected separately by a utility patent.
A design patent, in contrast, protects the ornamental or aesthetic appearance of a product rather than its function. The term originates in U.S. law, where ornamental protection is incorporated within the patent framework under the Patent Act of 1952. It covers features such as shape, configuration, pattern, surface ornamentation, or visual layout, provided they are not dictated solely by function. India follows a different structure. Functional inventions are governed by the Patents Act, 1970, while aesthetic features are protected independently under the Designs Act, 2000. Design protection in India is therefore not a category of patent but a separate statutory right. It protects visual features judged solely by the eye and is granted for ten years, extendable by five.
