Expired Patents and Public Domain After a patent has been in place for 20 years for utility patents and 14 years for design and plant patents, the invention becomes part of the public domain.

Prosecuting a patent generally means advocating for the best protection possible with the patent office. Once a patent issues, patent attorneys can help clients license the patent. If someone infringes the patent, patent attorneys enforce the patent in court. If a client is sued for infringement, patent attorneys defend their clients, trying to prove that the patent is in not infringed or is invalid.

There are three types of U. Utility patents protect four broad classes of subject matter: products, machines, compositions of matter, and processes. They also protect the way the invention is constructed or how it works. Design patents protect the aesthetic appearance of a product or a part of a product.

Virtually any product or portion of a product can be the subject of a design patent. Plant patents protect asexually reproduced plants. A patent can be revoked before it expires under three general circumstances. First, if the patent owner or a third party initiates a reexamination of the patent, and the patent office determines that the invention is not patentable.

Second, if it is successfully challenged in a Post Grant Review proceeding or an Inter Partes Review proceeding brought by a third party, or in a lawsuit brought by a third party in Federal Court.

Sometimes the patent applicant may disclaim some or all of the term.

By filing a terminal disclaimer, the applicant gives up the portion of the potential patent term if the application is granted beyond the term of the reference patent.

However, the filing of a terminal disclaimer does not affect Patent Term Extension of a patent. In large patent portfolios, a complex web of terminal disclaimers may propagate and crossover between different families of patents. As such, one must perform a careful analysis of the interplay between standard terms, terminal disclaimers, including the relative filing dates of the terminal disclaimers, and patent term adjustments, in order to determine the expiration dates for the patents in such portfolios.

Even in the absence of a double patenting rejection, a patentee may decide to disclaim or dedicate to the public the entire term, or any terminal part of the term, of a granted patent using a terminal disclaimer. The PTA extension is awarded by the patent office automatically when a patent is granted.

B-delay accrues when the patent office fails to issue a patent within 3 years after an application is filed or enters U. C-delay, which is not as common as A- and B- delays, includes adjustment of patent term for interferences, secrecy orders, and appeals. For example, a time duration may be counted for A-delay because the patent office fails to respond to a reply and also for B-delay because the examination time has been more than 3 years from the filing date.

Such overlap duration cannot be counted more than once. For patents related to products that require regulatory approval before entering into market, e. There are some limitations on PTE.

Consumers and the public benefit from both patented inventions as well as the inventions that the patent helps spur. Patents are essentially a monopoly, which is seen as a necessary means of making research and development a worthwhile investment. A patent may also expire if the inventor or owner fails to pay the required fee on time.

Design patents do not have maintenance fees. Utility patents will require a fee at the 3. The fee also must be paid during the USPTO's specific window for payment, which may change and generally is only a few months.

There also is a grace period that may be granted. The grace period allows the patent owner to pay the fee after the deadline. But if the fee is not paid during this time, the patent will expire. Under certain circumstances, such as extraordinary difficulty in paying the fee, the USPTO may allow the fee to be paid and patent retaken even after the grace period. The patent must also be renewed annually in order to justify the continued government grant of monopoly rights.

The fees increase as the patent nears the year mark, therefore decreasing the incentive to keep the patent if it's not economically useful. This patent expiration policy is carefully designed to attempt to balance innovation incentives by inventors with the larger public welfare. The exclusive economic use of the patent rewards the inventor for pushing human knowledge forward.

However, if all such inventions were restricted for a long time afterward, it would significantly slow down inventions by others and thus overall social well-being.
