Patent Term and Continuity Analysis for US 10,959,649

Date of Analysis: May 10, 2026

This analysis details the term adjustments, related applications, and projected expiration date for US Patent 10,959,649, based on data from the USPTO and other public patent information services.

Patent Term Adjustment (PTA)

A Patent Term Adjustment extends the term of a patent to compensate for delays caused by the USPTO during the prosecution of the patent application. For US patent 10,959,649, a significant PTA was granted.

• Total PTA Granted: 197 days.
• Source of Delay: The adjustment was granted primarily due to "B Delay," which occurs when the USPTO fails to issue a patent within three years of the application's filing date. The application was filed on January 29, 2015, and the patent was issued on March 30, 2021, a period well over the three-year mark, thus warranting the adjustment.

Patent Term Extension (PTE)

No Patent Term Extensions (PTE) were found for this patent. PTE is typically granted for delays caused by regulatory review (e.g., by the FDA) and is not applicable in this case as the invention is not a pharmaceutical or medical device requiring such review.

Continuity and Related Applications

A review of the patent's prosecution history and family data reveals the following:

• Continuation or Divisional Status: US patent 10,959,649 is not a continuation or divisional of any prior US patent application. It is an original application.
