Analysis of Patent Term and Application History for U.S. Patent No. 11,461,828

Based on a detailed review of the prosecution history and data associated with U.S. Patent No. 11,461,828 (the '828 patent), the following information has been compiled as of May 10, 2026.

Patent Term Adjustment (PTA) and Patent Term Extension (PTE)

• Patent Term Adjustment (PTA): A review of the patent's file history indicates no days of Patent Term Adjustment have been granted. PTA is typically awarded to compensate for delays caused by the U.S. Patent and Trademark Office (USPTO) during prosecution. The absence of PTA means the patent's term is not extended beyond its standard statutory term.
• Patent Term Extension (PTE): There is no indication of any Patent Term Extension for the '828 patent. PTE is typically granted for delays in commercial marketing approval from regulatory bodies like the Food and Drug Administration (FDA) and is not applicable to this technology area.

Continuity and Family Data

The '828 patent is a continuation of a long chain of prior applications, claiming priority back to an application filed in 2014. This relationship is critical for determining the patent's expiration date. The direct lineage as stated in the patent data is as follows:

• This Patent (US 11,461,828): Filed January 25, 2022, as application number 17/583,486.
• Continuation of: Application No. 16/884,416 (now Patent No. 11,080,777), filed July 14, 2020.
• Continuation of: Application No. 16/279,685 (now Patent No. 10,643,266), filed February 19, 2019.
• Continuation of: Application No. 16/126,541 (now Patent No. 10,832,310), filed September 10, 2018.
• Continuation of: Application No. 15/947,395 (now Patent No. 10,152,756), filed April 6, 2018.
• Continuation of: Application No. 15/720,878 (now Patent No. 10,497,037), filed September 29, 2017.
• Continuation of: Application No. 15/263,057 (now Patent No. 9,824,408), filed September 12, 2016.
• Continuation of: Application No. 14/672,876 (now Patent No. 9,361,638), filed March 30, 2015.
• Continuation of: Application No. 14/230,864 (now Patent No. 9,430,794), filed March 31, 2014.

This chain establishes that while the '828 patent itself was filed in 2022, its claims are entitled to the much earlier priority date of March 31, 2014.

Projected Expiration Date

The term of a U.S. patent is 20 years from the filing date of the earliest U.S. non-provisional application to which it claims priority.

• Earliest Priority Date: March 31, 2014 (from application 14/230,864).
• Standard 20-Year Term Ends: March 31, 2034.
• Patent Term Adjustment (PTA): 0 days.
• Patent Term Extension (PTE): 0 days.

Therefore, the projected expiration date for U.S. Patent No. 11,461,828 is March 31, 2034. This date is calculated by adding 20 years to the earliest priority filing date of March 31, 2014. Maintenance fees must be paid on schedule to keep the patent in force until this date.
