Key Takeaways

  • Patent law 101 governs the process of securing intellectual property protection for inventions that are new, useful, and non-obvious.
  • There are three main types of patents: utility, design, and plant patents, each protecting different forms of innovation.
  • Patent eligibility is limited under Section 101 of the Patent Act to inventions involving processes, machines, manufactures, or compositions of matter—not abstract ideas or natural phenomena.
  • The U.S. Patent and Trademark Office (USPTO) evaluates applications for novelty, non-obviousness, and usefulness before granting protection.
  • Inventors benefit from exclusive rights for 20 years (utility and plant) or 15 years (design) from filing, but must maintain fees and disclose the invention publicly.
  • Working with a patent attorney improves the chances of approval and ensures claims are written to provide maximum protection.

Patents 101 is a good starting point if you want information on obtaining a patent. You'll learn what you need to get started, what's included in a patent, and how to get one. You'll also find out if your creation is actually patentable and the different types of patents available.

Getting Started

You can try to obtain a patent on your own, but you might consider hiring a patent attorney who will represent you. Whether you do it yourself or not, you need several crucial pieces of information related to inventions and patents. 

The more you know, the better prepared you'll be. You'll be less likely to suffer some of the pitfalls that unwitting and unsuspecting inventors fall victim to. You'll also have the information you need to understand the many nuances of the law. A well-informed inventor can provide meaningful help to the team behind him or her. 

You can't patent an idea, but you can move your idea into a stage where it's patentable.

Understanding Patent Law 101

Patent law 101 refers to Section 101 of the U.S. Patent Act, which defines what kinds of inventions are eligible for patent protection. Under this section, patents can be granted for any new and useful process, machine, manufacture, or composition of matter—or any improvement thereof—so long as it meets the standards of novelty, non-obviousness, and utility.

However, certain categories are excluded from patent eligibility. These include abstract ideas, laws of nature, and natural phenomena. Courts have repeatedly ruled that inventions that merely apply these concepts without an inventive step do not qualify for patents. For example, a mathematical formula or natural discovery cannot be patented unless it’s applied in a novel and concrete way.

In practical terms, patent law 101 ensures that patents reward true innovation—protecting inventors while keeping fundamental scientific principles available for public use.

What's in a Patent?

A patent consists of several parts.

The specification begins with a brief description of the field of the invention. It's a detailed presentation of your invention. It should include prior art, and it has to include the best method of using the invention that you know of. You also must include descriptions of the invention's essential components.

The background section details work performed in the past (including prior art) and any shortcomings. You must disclose all the prior art that you know about. Include drawings if that makes it easier for someone to understand the invention.

Next, you include a disclosure. This covers a broad scope of what you consider your invention to be and any advantages it has. The summary outlines the theory the invention rests on and includes complete details on how to use the invention.

Every implementation is referred to as an embodiment. The preferred one is regarded as the best implementation. The section on industrial applicability shows applications in which your invention can be used.

Claims begin with broad descriptions of the invention's essential elements and then move into more narrow descriptions. Narrow claims may make it easier to get a patent, but if they're too narrow, it's possible for someone else to work around your patented invention.

A patent has to include the following: 

  • An oath, or statement, saying you believe you're the first person to invent the item or process 
  • Your signature 
  • Any required fees

Types of Patents Explained

There are three main types of patents available through the USPTO, each designed for a different form of innovation:

  1. Utility Patents – The most common type, covering new and useful processes, machines, manufactured articles, or chemical compositions. Examples include medical devices, computer software, and industrial equipment.
  2. Design Patents – Protect the ornamental design or aesthetic appearance of a functional item, such as a smartphone’s shape or a chair’s unique form. Design patents last 15 years from the date of grant.
  3. Plant Patents – Granted for new and distinct plant varieties that are asexually reproduced, like hybrid roses or fruit trees.

When filing, inventors must specify the correct patent type, as each involves distinct requirements, fees, and review criteria.

How Do You Get a Patent?

Before you make your creation public, you should think about filing a patent. This is important if you believe you have a commercially viable creation. If you go public and don't have a patent for it, your idea could be stolen and used by someone else. If you don't file before going public with your invention, you could also forfeit the rights to patents in other countries. 

You'll begin by visiting the U.S. Patent and Trademark Office website and filing an application there. Because the USPTO has such specific guidelines on how to assemble an application package (including the way any drawings are presented), you might want to enlist the aid of a lawyer who's experienced in patent law.

To choose a patent attorney wisely, consider the following: 

  • Technical competence 
  • Prior experience in such cases 
  • Inventor preferences

Inventors must be cooperative in filing and prosecuting patents. While a patent lawyer is educated in the general field of your invention, he or she isn't likely to have the same degree of expertise as you, the person who invented it. To get appropriate patent protection for your invention, you should have a good rapport with your chosen attorney.

Your invention will have the status of “Patent Pending” when you turn in your application. A status of “Patent Pending” gives other people notice and warning about potential consequences in case they try to copy your invention. You can also market your invention as being innovative once you have this status. While your patent is pending, your application will be reviewed by the Patent Office.

Arm yourself with as much information as you can find if you feel you have a marketable invention. Taking the required steps to protect your creation will ensure you retain all the necessary rights.

The Patent Examination Process

Once a patent application is filed, the USPTO assigns it to an examiner trained in the relevant technical field. The examiner reviews the application to determine whether:

  • The invention is novel, meaning it has not been disclosed in prior art.
  • It is non-obvious, not an expected variation of existing inventions.
  • It is useful, having a specific and practical purpose.

If deficiencies exist, the examiner issues an office action, allowing the inventor to respond, amend claims, or provide clarification. This process can take several rounds before the application is allowed or rejected.

Upon approval, the patent is published in the Official Gazette, granting the inventor exclusive rights to make, use, and sell the invention for the statutory term. To maintain validity, inventors must pay maintenance fees at 3.5, 7.5, and 11.5 years after issuance.

Why Patent Protection Matters

Patents play a key role in encouraging innovation by granting inventors a limited-term monopoly. This exclusivity incentivizes research and development while requiring inventors to publicly disclose technical information for others to build upon once the patent expires.

Businesses often leverage patents for:

  • Licensing opportunities, generating revenue through partnerships.
  • Market exclusivity, deterring competitors.
  • Valuation and investment, where patent portfolios increase company worth.

Without proper protection, competitors could replicate and profit from an invention without authorization. For this reason, consulting a qualified patent attorney can help structure a strategy for protection, enforcement, and monetization under patent law 101 principles.
