While coming up with an invention may be difficult, getting a patent is pretty simple. Thousands are issued each year. A patent is a document drawn up by the inventor that protects the product for up to 20 years. It gives the inventor the right to not allow others to reproduce, use or sell their product. Here are some steps for writing a patent for your invention.

Decide which kind of patent you're applying for-a plant patent, a design patent or a utility patent.

Compose a declaration of your product that includes all of the following: each inventor's name, address and citizenship; a statement from each inventor attesting to the authenticity of the product and their consent to disclose all information pertaining to it; references to any prior patent filings for this product; and a power of attorney document.

Provide an assignment of invention rights. This statement gives the rights to whoever invented the product and should include the title of the invention, the names of the inventors, the name and address of the person assigning the rights, and the date of execution of the patent.

Include a small-entity form. You must file a claim of small-entity status, the inventor must sign it and you must include payment of the reduced filing fee.

Include a drawing of the invention. Te receive an issue date, you must include drawings of the product that include every feature of the invention that was specified in the claim.

Provide the specifications of the invention. This describes every aspect of the invention from its title to how it works to how you invented it.

Provide Information Disclosure Statements.

Submit the final product. The final patent application should be submitted with a cover sheet that lists the title of the invention, the name of each inventor and the claim for small-entity status.
