Basics of US patents and the patent system.

The patent system plays an important role in stimulating the economy and advancing the quality of life in the United States. It serves as an incentive for innovation by giving inventors an exclusive right to their inventions for a limited period of time. It also increases and hastens the publication of useful knowledge by requiring inventors to disclose their invention to the public. Patents are particularly important in the pharmaceutical and biotechnology industries because they provide a mechanism by which the extremely high product development costs may be recouped. The United States Patent and Trademark Office acts as a gatekeeper in the patent system to prevent patents that do not meet the legal requirements from being thrust on the public. The legal requirements for obtaining a patent are discussed, particularly as they relate to pharmaceutical and biotechnological inventions. The process of examining an application for a patent is briefly described, along with some of the burdens faced by examiners when deciding the patentability of therapy-related inventions.
