What Does Expired for Non-Payment Mean for Patents?

By Brenna Davis

A patent is a right conferred by the government to intellectual property that gives the patent-holder sole authorization to sell, make or distribute the item. Patents in the United States can only be granted by the U.S. Patent and Trademark Office. Inventors and discoverers of new, useful, non-obvious inventions can patent their items, granting them sole rights to profit from and sell the item for a set period of time. The patent office also offers patents for plants and for designs. To retain a patent, you must pay patent maintenance fees to the patent and trademark office. If you do not pay these fees, your patent will expire.

Types of Patents

The USPTO offers three types of patents. Utility patents are available to inventors or discoverers of new inventions or processes. Utility patents are the most commonly sought-after patent. Design patents are offered to those who invent or discover the design for an invention or process. Inventions, designs and processes patented through design or utility patents must be unique. Plant patents are available to those who invent or discover a new plant and who cause such plant to reproduce asexually. Plant and utility patents last for 20 years from the date of patent application, whereas design patents last for 14 years.

Patent Maintenance Fees

To receive a patent, you must apply through the USPTO. After your patent is granted, you are required to pay patent maintenance fees three and one-half years, seven and one-half years and 11 and one-half years after the date of first application. Patent fees increase at each due date and they vary, depending upon whether the patent holder is classified as a small entity by the USPTO. The USPTO defines a small entity as a person, non-profit organization or small business, "...who has not assigned, granted, conveyed, or licensed, and is under no obligation under contract or law to assign, grant, convey, or license, any rights in the invention." The patent office will not notify you personally when the fee is due, but the office issues a weekly list of patents for which maintenance fees are currently payable. Maintenance fees may be paid up to six months in advance.

Patent Expiration

There is a six-month grace period after the due date of patent maintenance fees during which your patent will not expire. If you pay during this period, you will be subject to a late payment surcharge. Failure to pay during this time, however, will cause your patent to expire.

Patent Reinstatement

Patents may be reinstated up to two years after expiration due to nonpayment. To qualify for reinstatement, the patent holder must demonstrate that the nonpayment was unavoidable or unintentional. Examples of "unavoidable" patent late payments might occur when the patent holder is debilitated by surgery or has died and his heirs did not realize the payment must be made. The late fees for unavoidable non-payments are lower, but require documentation. "Unintentional" late payments do not require documentation and are accepted at the discretion of the patent office. However, your rights to the patent are not protected while the patent is expired. 35 U.S.C. 41(c)(2) states that someone who sells an expired patent when it expires due to nonpayment is not subject to charges of patent infringement. After your patent is reinstated, however, others may not sell the item.

How to Get a Temporary Patent

A provisional patent offers some of the same protections of a non-provisional patent, such as legal protection of your invention from use by someone else, but is cheaper than a non-provisional patent and expires 12 months from the filing date. An applicant who files a provisional application must file a corresponding non-provisional application for patent during the 12-month pendency period of the provisional application to benefit from the earlier filing of the provisional application. An alternative to filing a corresponding non-provisional application is to convert the provisional application to a non-provisional application by filing a grantable petition requesting such a conversion within 12 months of the provisional application filing date. If you do not do this, you may be prevented from filing a patent for your invention in the future. Once granted a provisional patent, you may use the term "patent pending" on your invention.

How to Patent a Toy Idea

It is impossible to patent a mere idea -- you must first reduce it to tangible form. To be eligible for a patent, your toy must be unique, useful and non-obvious. Of these three patent requirements, non-obviousness is the most difficult to meet, due to the low-tech nature of most toys -- your toy must exhibit a degree of innovation beyond the "state of the art" that would not be obvious to a skilled toy manufacturer. Toy designs are normally filed as utility patents, which expire 20 years after the original patent application filing date.

How Long Is a Patent Valid?

A patent is a governmental grant of a short-term monopoly to inventors. U.S. patent laws enable a patent holder to prevent others from making, using or selling the patented invention for a specific time period. How long a patent remains valid depends on the type of patent and other factors.
