U.S. patents include three different types of patents: invention patents, design patents and plant patents. The United States Patent and Trademark Office (USPTO) issues the following three types of patent certificates:

1. Invention patent (Utilitypatent): A method, machine, product or combination of things, or a new and useful improvement. Obtain a patent under the provisions and conditions prescribed by this Act.

2. Patent for design: Anyone who creates a novel, original and decorative product design may obtain a patent in accordance with the provisions and requirements of this law.

3. Plant patent (Patent for plant): Anyone who invents, discovers and asexually propagates any special and new plant varieties, including changes, variants, mixtures and newly discovered plant seedlings in cultivation, may apply for a patent based on this patent. The Act provides for patenting, but does not cover plants propagated from tubers or plants found in a non-cultivated state.

4. The provisional application (Provisional Application) must be converted into a formal application within one year: only the description and drawings must be submitted, and it must be converted into a formal patent application within one year, or a new patent application must be filed with this provisional application as priority. Formal application. Enjoy the filing date for provisional applications. Since the patent term of a provisional application will be 20 years from the filing date of the provisional application, most applicants are unlikely to choose to directly convert the provisional application into a general application.

Note: There is no type of patent protection for new inventions in the United States.
