What is a United States Patent?

What are the various types of United States Patents?


There are several types of United States Patents. The two most common types are utility patents and design patents.

A utility patent protects a new and useful process, machine, manufacture, or composition or any improvement thereof. This is the most common type of patent and it is what most often associate with patents.

A design patent protects a new, original and ornamental design for an article of manufacture. As such, a design patent protects the ornamental appearance of an invention. As such, this is a somewhat narrower patent in terms of the scope of protection as compared to a utility patent.

Provisional Patent Application


A provisional patent application is an application to obtain a patent. It does not get examined by a patent examiner. The applicant has one year to amend the patent application to a utility patent application which must be based on the disclosure contained in the provisional application. If the utility application claiming priority of the parent provisional is filed within the one-year time window, the applicant’s utility patent application is afforded the earlier filing date of the parent provisional.
