Inventors who hope to monetize or at least protect their inventions will need to get acquainted with the basics of patent law. This includes a working knowledge of the main terms related to patents. Below you will find an alphabetical list of definitions for frequently used words and phrases related to patents. See FindLaw's Patents section for additional articles and resources.

Application - An application for patent filed under federal law that includes all types of patent applications (i.e., utility, design, plant, and reissue) except provisional applications.

Claims - Patent claims define the invention and are what aspects are legally enforceable. The specification must conclude with a claim particularly pointing out and distinctly claiming the subject matter which the patent applicant regards as his invention or discovery.

Oath - A solemn declaration before another, complying with the laws of the state or country where made, that the document in which an applicant for patent declares that (1) he or she is the original or sole inventor, (2) shall state of what country he or she is a citizen, (3) that he or she has reviewed and understands the contents of the specification and claims which the declaration refers to, and (4) acknowledges the duty to disclose information that is material to patentability.

Patent - A property right granted by the Government of the United States of America 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.
Patent Application (See "Application")
Patent Infringement - Any unauthorized making, using, offering to sell, selling or importing into the United States any patented invention is considered infringement.
Patent Number - Unique number assigned to a patent application when it issues as a patent.
Patent Pending - A phrase that often appears on manufactured items. It means that someone has applied for a patent on an invention that is contained in the manufactured item. It serves as a warning that a patent may issue that would cover the item and that copiers should be careful because they might infringe if the patent issues. Once the patent issues, the patent owner will stop using the phrase "patent pending" and start using a phrase such as "covered by U.S. Patent Number XXXXXXX." Applying the patent pending phrase to an item when no patent application has been made can result in a fine.
Patentable - Suitable to be patented; entitled by law to be protected by the issuance of a patent.
Plant Patent Application - Applications to protect invented or discovered, asexually reproduced plant varieties.
Plant Patent - May be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant.

Prior Art - Any pre-existing knowledge, process, or product in the field or marketplace that can impact the validity (as to novelty or "obviousness") of a patent claim.
Restriction - If two or more independent and distinct inventions are claimed in a single application, the examiner may require the applicant to elect (designate) a single invention to which the claims will be restricted (limited to). This requirement is known as a requirement for restriction (also known as a requirement for division).
Scope - What is included; as in the scope of a patent claim.
Specification - A written description of the invention and the manner and process of making and using the same.
Substitute Patent Application - An application which is in essence a duplicate of a prior (earlier filed) application by the same applicant abandoned before the filing of the substitute (later filed) application; a substitute application does not obtain the benefit of the filing date of the prior application.
Term of Art - An expression or phrase that has a defined meaning when used in a particular context or knowledge environment (such as the patenting process, pharmaceuticals, computers, etc.).
Utility Patent Application - A patent application that can be used to protect useful processes, machines, articles of manufacture, and compositions of matter.
Utility Patent - A utility patent may be granted to anyone who invents or discovers any new, useful, and nonobvious process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof.
Withdrawn Patent - An allowed application for patent in which the applicant files correspondence to withdraw the patent from issue; thus preventing it from issuing on the patent issue date. The printed document is sometimes available on the day of publication, but is later retracted and will not be available in the patent database.
