Lesson 14: What is a Patent?

Welcome to Lesson 14 of our Exploring Intellectual Property Law series. In this lesson, we will discuss patents, a critical component of intellectual property law.

Definition of a Patent

According to the United States Patent and Trademark Office (USPTO), a patent is an intellectual property right granted to an inventor to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States for a limited time, in exchange for public disclosure of the invention when the patent is granted.

Types of Patents

There are three main types of patents:

  • Utility patents

To learn about these types of patents, you can proceed to Lesson 15: Types of Patents.

Requirements for a Patent

To be patentable, an invention must meet the following criteria:

  • Novelty
  • Non-obviousness
  • Utility

The sections below explain these criteria in more detail.

Novelty

The invention must be new. This means that it must not have been previously disclosed to the public before the date of the patent application. If an invention is already known, it cannot be patented. This criterion ensures that patents are only granted to truly new inventions.

Non-obviousness

The invention must not be obvious to someone with knowledge and skills in the subject area. This requirement prevents the granting of patents for trivial advancements or combinations of existing ideas.

Utility

The invention must be useful. This means that it must have some practical application or be capable of some kind of useful result. This requirement bars the patenting of inventions that are purely theoretical or have no real-world application.

Benefits of Patents

Patents provide several benefits to inventors and society, including:

  • Encouraging innovation by providing exclusive rights
  • Promoting disclosure of information to the public
  • Providing a source of revenue through licensing and sales

Limitations and Challenges

While patents offer significant advantages, they also come with limitations and challenges, such as:

  • High costs of obtaining and maintaining patents
  • Complex and lengthy application process
  • Potential for patent disputes and litigation
