Patent Basics For Makers
2026-02-11 | By Maker.io Staff
Patents help inventors protect their inventions from being used, produced, marketed, or sold without their consent. Patent laws can vary wildly between countries, and the many types of available patents can quickly confuse makers. This article explores the basics of United States patents, what can be protected, and the filing process.
What is a Patent?
A patent is a legal document that grants its holder the right to stop others from making, using, selling, or importing the protected invention. It doesn’t give the inventor permission to build or market the invention, but rather the power to take legal action against infringement. As a consequence, patents protect an inventor’s intellectual property by giving them exclusive rights to their creation. For example, if someone invents a new kind of 3D printer nozzle that uses less filament, a patent lets them prevent others from copying or selling that design without approval.
Patents are generally valid only in the country that issues them, and laws differ widely between regions. In the U.S., patents are examined and granted by the United States Patent and Trademark Office (USPTO). A patent attorney can help ensure that applications meet all formal requirements and advise on international protection through treaties.
Types of U.S. Patents
The USPTO recognizes three types of patents—the one to apply for depends on the invention’s purpose. Utility patents cover new or improved and useful processes, machines, articles of manufacture, or compositions of matter. Design patents protect new, original, and ornamental designs for an article of manufacture. Plant patents cover distinct, new plant varieties that are asexually reproduced, such as a new apple variety.

Utility and design patents are usually most relevant for makers, as these types cover machines, tools, mechanical parts, manufacturing processes, and unique ornamental designs. However, the exact type of patent depends on intent. For example, a fork with decorative ridges that happen to improve grip would likely be a design patent. On the other hand, ridges intended primarily for utility, for example, to help people with tremors hold a fork more easily, would favor a utility patent. The choice can be nuanced, so consulting a patent attorney or the USPTO is recommended.
The validity of U.S. patents is limited. While utility patents typically last 20 years from the filing date, design patents last 15 years from the grant date.
What Can Be Patented?
An invention must meet certain criteria to be eligible for a patent. It must be new or novel, meaning it hasn’t been done before. It must also be useful, so it actually works and isn’t just a theory or idea. The inventor must provide a clear description of how to make and use the invention. Finally, it cannot be obvious, meaning it can’t be an evident modification of something already known.
There are a few things that cannot be patented. Examples include laws of nature, physical phenomena, abstract ideas, or suggestions. The USPTO also does not grant patents related to nuclear material or atomic energy used in weapons.
What’s Needed For a Patent?
The exact information and filing process required to apply for a patent depends on the patent type and the issuing country. However, there are a few steps they all have in common.
The process starts with preliminary research, since inventors must ensure that their invention meets the eligibility criteria and that it has not been patented before. Patent offices generally offer online search tools for this purpose.
After ensuring that an invention meets the criteria, inventors have to decide whether they want to file a provisional or non-provisional (full) patent. Provisional patents have more relaxed application rules, making them simpler and cheaper to file. However, they expire after twelve months, and they act more like a reserved sign that inventors can put up while working out a non-provisional patent. Full patents are more costly and follow a formal application process, involving examination by the issuing office.
In the United States, a full patent application includes several key components. It requires forms for the application and fees, along with a patent data sheet. The specification forms the core of the application, containing the title, background, summary, detailed description, claims, and a brief abstract. Drawings that illustrate the invention have to be included if necessary, and the inventor(s) must submit a signed oath confirming they are the original creator(s) and have the right to file.
After submission and paying the fees, the application enters the examination process. During this stage, the patent office reviews the submission, issues feedback or objections, and allows responses or amendments before a final decision.
Summary
Patents help inventors protect their creations, preventing others from making, using, or selling them without permission. In the U.S., the most relevant types for makers are utility patents, which cover how something works, and design patents, which cover how something looks. To qualify, an invention must be new, useful, clearly described, and non-obvious.
The filing process usually starts with research, followed by a decision between a provisional or full (non-provisional) application, and includes submitting forms, specifications, drawings, and an oath. After submission, the patent office reviews the application, and inventors can respond to feedback before a final decision.
