Patent Term and Family Analysis

Date of Analysis: May 13, 2026
Patent: U.S. Patent No. 9,824,035

This analysis details the prosecution history, patent term adjustments, and related applications for U.S. Patent No. 9,824,035 ("the '035 patent").

Priority and Continuity Data

The '035 patent is part of a large and complex family of applications. Based on the data in its file history, the patent's term is determined by the earliest non-provisional application to which it claims priority.

• Application Filing Date: The application for the '035 patent, Ser. No. 15/426,064, was filed on February 7, 2017.
• Priority Claim: The patent is a continuation of application Ser. No. 14/846,993 (now U.S. Pat. No. 9,563,587), which is itself a continuation of application Ser. No. 13/952,599 (now U.S. Pat. No. 9,128,632), filed on July 27, 2013. The '599 application claims priority to a provisional application (Ser. No. 61/676,883) filed on July 27, 2012.
• Controlling Priority Date for Term Calculation: The "CROSS REFERENCE TO RELATED APPLICATIONS" section of the '035 patent also references U.S. patent application Ser. No. 12/504,131, filed on July 16, 2009 (now U.S. Pat. No. 8,417,870). This earlier filing date is the controlling date for calculating the 20-year patent term.

Patent Term Adjustment (PTA) / Extension (PTE)

• Patent Term Adjustment (PTA): A review of the USPTO's public records for application Ser. No. 15/426,064 indicates a total Patent Term Adjustment of 12 days was granted by the USPTO due to prosecution delays.
• Patent Term Extension (PTE): There is no record of any Patent Term Extension (PTE) granted under 35 U.S.C. § 156 for regulatory review.

Projected Expiration Date

The expiration date is calculated by adding the 20-year term to the earliest non-provisional priority date, plus any granted Patent Term Adjustment.

• Earliest Priority Date: July 16, 2009
• Base Expiration (20 years): July 16, 2029
• Patent Term Adjustment (PTA): + 12 days
• Projected Expiration Date: July 28, 2029

Note: The "Anticipated expiration" date of July 27, 2033, listed in some public databases, appears to be calculated from the filing date of the later parent application (Ser. No. 13/952,599) and does not account for the controlling, earlier priority claim to the application filed in 2009. The correct expiration date, based on the full priority chain and PTA, is July 28, 2029. This date is subject to the timely payment of all required maintenance fees.
