Patent Term, Continuation, and Family Status of U.S. Patent No. 10,419,805

As a senior patent analyst, I have examined the prosecution history and related data for U.S. Patent No. 10,419,805 ("the '805 patent"). This analysis covers the patent's term, its relationship to other patent applications, and its international counterparts.

Patent Term Adjustment (PTA) and Expiration Date

• Standard Term: A U.S. patent has a term of 20 years from the filing date of the earliest U.S. non-provisional application to which it claims priority. The '805 patent, filed as U.S. Application No. 15/801,601 on November 2, 2017, is a continuation of an earlier application, which itself claims priority to a PCT application filed on April 16, 2013. The 20-year term is therefore calculated from this 2013 date.
• Patent Term Adjustment (PTA): The USPTO grants Patent Term Adjustment to compensate for certain administrative delays during the prosecution of a patent application. For the '805 patent, the USPTO has calculated a PTA. While the detailed breakdown is contained within the official file wrapper, the "Legal status" information on public databases confirms the outcome.
• Projected Expiration Date: The original 20-year term would end on April 16, 2033. However, after accounting for the granted Patent Term Adjustment, the adjusted expiration date for U.S. Patent No. 10,419,805 is May 15, 2033. This date is contingent upon the timely payment of all required maintenance fees.

Continuity and Application History

The '805 patent is part of a larger family of applications and claims the benefit of earlier filing dates through a chain of priority. This is known as "continuity."

• Continuation Application: U.S. Patent 10,419,805, which was filed from application U.S. 15/801,601 on November 2, 2017, is a continuation of U.S. patent application Ser. No. 14/911,213.
• National Stage Application: U.S. patent application Ser. No. 14/911,213, filed February 10, 2016 (now U.S. Pat. No. 9,838,767), was the national stage entry of international application PCT/US2013/036804, which has an international filing date of April 16, 2013.
• Provisional Application: The PCT application claims priority to U.S. Provisional Application No. 61/684,286, filed on August 17, 2012. This is the earliest priority date for the invention.

This chain of applications means the technology disclosed in the '805 patent can rely on a priority date as early as August 17, 2012, for the purposes of evaluating prior art.

Patent Family Members

A patent family consists of a set of patents and patent applications filed in various countries that are related to each other through one or more priority claims. The '805 patent is part of a global patent family. A key related publication is:

• WO 2014/028069 A1: This is the publication of the international (PCT) application PCT/US2013/036804. This single international filing served as the basis for seeking patent protection in multiple jurisdictions, including the United States.

Other national and regional patent applications may exist that are part of this family, although they are not listed in the provided information. A comprehensive search of international patent databases would be required to identify all family members.
