The American Inventors Protection Act, 35 U.S.C. Sn. 154(d) allows the inventor rights under pending patent to claim damages for infringement. This statute gives the inventor provisional rights to obtain reasonable royalties from those who use, sell, offer to sell or import a product or invention, which is under the consideration of USPTO, or in “patent pending” mode. Regardless of the “patent pending” notice in the product, the inventor or rights holder, will have to send an actual notice to the infringer informing the patent is under consideration and asking to stop the infringement, usually as a “cease and desist notice". They can however make the claim for damages only after the receiving the patent.
The ability of inventors or right holders to assert such rights, starts when the USPTO publishes the patent application, which takes place 18 months after the filing date or priority date claimed by an application. Such claims for reasonable royalties however, do not hold unless the claimed infringement is identical to the invention described in the published patent application. The inventor or right-holder, also has to bring in action against such infringers within six years after obtaining the patent, failing which the claim to royalties lapses. Infringers also have the option to challenge the application for patent at the USPTO within two months of publication, on reasonable grounds.
In real-life, “Patent pending” may be worthless for products with short life cycles, as by the time the inventor issues a cease-and-desist notice to the infringer, the product demand may already have run its course anyway. Competitors and infringers however, remain less likely to infringe on capital-intensive products with “patent pending” notices, for such products require a long time to recoup their investments, forcing infringers to ignore “cease and desist notices” and risk lawsuits claiming royalties. Other infringers, wanting to milk a lucrative market when the opportunity exists, may actually infringe deliberately, especially when the product requires low start up costs, hoping to negotiate royalties when eventually slapped with a lawsuit.
The marking of articles as “patented” or “patent pending” when it is not the case, is against the law and attracts a penalty.
