What Is Patentable Subject Matter and what it includes?


A patentable subject matter refers to the standards set forth by the USPTO (United States Patent and Trademark Office). These standards are set for a patent application in order to receive patent protection. Also, the USPTO law defines patentable subject matter as: “Whoever invents or discovers any new and useful process, the machine, manufacture, or composition of matter or any new and useful improvement thereof may obtain a patent therefor, subject to the conditions and requirements of this title.”

Moreover, an invention must satisfy 2 criteria in order to qualify as patentable subject matter. One of them is statutory and the other one is judicial. The requirements are:

  • Firstly, the subject matter of the invention must fall under the category of the machine, process, manufacture or composition of matter.
  • Secondly, the subject matter must not fall within the exceptions recognized by the court; that are, physical phenomena, laws of nature, and abstract ideas.

Patentable Subject Matter: Terminologies

You must understand the difference between what patentable subject matter is and what isn’t. For this, you are required to know about certain key terms used. They are:

Utility patent preserves the working and use of a particular product or invention. It includes process, machine, products, or matter composition.

Moreover, they are meant for the invention having a useful purpose, for example, a new engine for cars.

A Utility Patent lasts for 20 years from the date of filing, if you file it after 8 June 1995.

  • Design Patents

The design patent deals with the visual shape or design upgrade to the article of manufacture. It describes a new ornamental feature of the item and protects the way how an invention looks.

The design patents get a time period of 15 years from the date of issue if you file it after 13 May 2015.

For example, you can attain a utility patent for a new function of the watch and you can also attain a design patent for it if you made any new ornamental changes.

  • Plant Patents

You may obtain a Plant Patent if you discover or reproduce (through cross-pollination) a new variety of the plant. The plant must not be present in any uncultivated state.

A Plant patent also has a lifespan of 20 years from the filing date, if filed after 8 June 1995.
