What is a utility patent?
A utility patent is a type of patent issued by the United States Patent and Trademark Office (USPTO) that protects the functional aspects of an invention. It grants the patent holder the exclusive right to make, use, sell, and license the invention for a period of up to 20 years from the filing date, provided that maintenance fees are paid.
What Does a Utility Patent Protect?
Utility patents cover new and useful inventions or discoveries related to:
- Processes: Methods of doing something (eg, a manufacturing process or software algorithm).
- Machines: Mechanical devices or apparatuses (eg, engines, medical devices).
- Articles of manufacture: Physical products (eg, tools, gadgets, or consumer goods).
- Compositions of matter: Chemical compositions, formulations, or compounds (eg, pharmaceuticals, adhesives).
- Improvements: Enhancements or modifications to existing products or processes.

Utility Patent vs. Design Patent
feature | Utility Patent | Design Patent |
|---|---|---|
Protects | Functional aspects of an invention | Ornamental appearance only |
Duration | 20 years from filing date | 15 years from grant date |
Examination | More complex and rigorous | Typically faster and simpler |
Application Cost | Higher due to complexity | Lower cost |
Examples | Machines, processes, chemical compounds | Product shapes, patterns, or icons |
Key Takeaway
A utility patent protects the functionality and structure of new and useful inventions, offering exclusive rights for up to 20 years. It is the most common type of patent, covering a wide range of technological and scientific innovations.
