One of the most noticeable proposals to be enacted by the Patent Reform Act of 2007 is a sweeping change of the patent application process switching it from a “first to invent” system into a “first to file” system.Currently, the United States is the only country working under the “first to invent” system, meaning when similar patent applications are filed, priority will be given to the one claiming the earliest invention date and not determined by the date of the actual application filing.This has led to complications in the U.S. application process, most notably, requiring the United States Patent and Trademark Office to hold lengthy interference hearings to correctly identify the date at which similar patents were invented in order to give proper priority.With the switch to a “first to file” system, priority for applications of similar patents will be wholly determined by the date at which the application was filed instead of the date the patent was claimed to be invented on.
