• Provisional Patent Application (US Only): Simplified legal and form requirements; not subject to exam; inexpensive filing fee; cannot mature to issued patent • Regular US Application (Nonprovisional): complex legal and form requirements, subject to exam; can mature to issued patent; more expensive • International Application (PCT): single application for 115 countries; very expensive A patent is in effect for 20 years from the date of filing the application. What are the barriers to patentability? One of the largest barriers to patentability is public disclosure of an invention to the public before a patent application is filed. The application can take up to several years to be processed by the U.S. patent office. Fortunately, researchers can disclose their invention after an application has been filed even if a patent has not been awarded.
