Legal Document That Protects the Rights of an Owner's Invention

By Mary Jane Freeman

The owner of an invention can protect his right to make, use and sell his invention by obtaining a patent. Once an application is submitted and approved by the U.S. Patent and Trademark Office, it serves as proof that the owner enjoys patent rights over his invention.


A patent as an intellectual property right granted to an inventor by the U.S. Patent and Trademark Office. The patent prevents others from "making, using, offering for sale, or selling" the patent holder's invention for a certain period of time. Patents come in three forms: utility patents, design patents and plant patents.

Proof of Patent

To obtain a patent, an inventor must apply for one. Applications may be submitted by mail or online to the U.S. Patent and Trademark Office. The USPTO publishes most patent applications, usually 18 months after the earliest effective or priority date claimed by the application. Once the USPTO grants a patent, an applicant receives patent rights for a term of 20 years, usually beginning from the date of the application. Thus, an approved patent application can serve as proof of an existing patent and ownership rights in an invention.

The Process of Opening an Estate

Although the process of opening an estate varies from state to state, many aspects of the process are essentially the same. Often, the person who gets the proceedings started is the person named as executor in the decedent's will. If the decedent did not make a will -- and by extension, failed to name an executor -- a family member or close family friend may start proceedings by filing paperwork with the probate court in the county in which the decedent lived.

How to Write a Provisional Patent Application

Filing a formal patent application is expensive and time-consuming, and usually requires the services of an experienced patent attorney. You can, however, file a provisional patent application with much less effort and without retaining an attorney. Filing a provisional patent application will put your invention in "patent pending" status for 12 months, preventing anyone else from filing for patent protection for the same invention. This 12-month window will buy you time to file a formal application.

Ownership vs. Inventorship of a Patent

A patent grants the owner of the patent a temporary legal monopoly on a bundle of rights related to an invention, including the right to profit from it. The inventor, however, is not always the owner of a patent. Patent law provides a number of ways in which someone can obtain patent rights over technology invented by another.
