Utility Patent Application Guide

A utility patent protects how a claimed product works. Since there are three types of patents – Utility, Design and Plant, it is important to understand the distinction among the three.  A utility patent example can help get an idea of how a utility invention patent application looks like.

To begin with, let us first understand what a utility patent protects. It protects the product, process or machine. In other words, if you come up with a new process, chemical compound, method or a manufactured product it gets protected as a utility patent. Also, it encompasses improvements (innovations) in the existing products.

A utility patent is further divided into three categories:

  • Chemical
  • Electrical and
  • Mechanical

Once you understand that your invention falls under the category of a utility patent make sure it falls under the patentability criteria set by the USPTO. You can find this out by conducting a thorough patentability search.

How Utility Patent Examples are Important?

It works this way; you have come up with an invention and looking forward to getting a patent for it. Or maybe you are in the middle of creating an invention but want to secure it as your own legally.  But, at this very step, you are confused about how to take it further. Consider filing a provisional application.

  • If you are in the middle of inventing something but are not ready for final submission to the USPTO consider filing a provisional application.
  • It is a cheaper way of securing your invention at least for a period of a year. After this period file a non-provisional patent application for the patent grant of 20 years.
  • It temporarily secures the invention in your name.
