Filing a provisional patent application in the U.S. is often a useful strategy for start-up tech companies. A provisional patent application allows a company to preserve an earlier filing date at a minimal expense and delays a much more significant expenditure associated with a non-provisional application by one year. By the anniversary of the provisional application filing, a non-provisional application must be filed in order to take benefit of the provisional filing date. A provisional application is especially useful if it provides a detailed description of the invention and preferably explains valuable alternative implementations. Otherwise any new subject matter added to the non-provisional application will not be given the benefit of the provisional application filing date.
Options for Non-Provisional Patent Filings
With the enactment of the Leahy-Smith America Invents Act (AIA) in 2011, there are now multiple opportunities to speed up the patenting process for which companies, such as those focusing on nanotechnology related inventions, can take advantage when filing a non-provisional. The two main options are (1) prioritized examination and (2) accelerated examination.
