The effective filing date is the date on which a patent application is deemed to have been submitted. This date is significant as it establishes the invention’s priority and prevents prior art from being considered. It also determines the timeframe for filing in other countries and establishes the date of constructive reduction to practice. The child application typically inherits the filing date of the parent application to demonstrate priority under the continuity doctrine.
The effective filing date of a patent application is crucial as it determines the invention’s priority and the ability to file in other countries. It also marks the closing of prior art and establishes the date of constructive reduction to practice. For instance, if an inventor files a patent application on January 1, 2021, that becomes the effective filing date, allowing them to claim priority over similar inventions filed after that date, even if the application is approved later. In the case of a continuing application, the effective filing date may match the parent filing date, meaning the priority is based on the original application. These examples highlight the significance of the effective filing date in determining invention priority and international filing eligibility, as well as its potential alignment with the parent filing date in continuing applications.
