Analysis of Patent Term, Adjustments, and Family for US 12,409,014 B2

As of May 6, 2026, the following details pertain to the term and application history of US patent 12,409,014 B2.

Patent Term Adjustment (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): A search of the USPTO's public records for application number 18/604,331, which issued as patent 12,409,014 B2, indicates that no Patent Term Adjustment (PTA) has been granted. PTA is awarded to compensate for certain administrative delays by the USPTO during prosecution. The absence of a PTA grant means the patent term is not extended for this reason.
• Patent Term Extension (PTE): There is no indication of any Patent Term Extension (PTE). PTE is typically granted for delays caused by pre-market regulatory review by agencies like the FDA and is not applicable in this case.

Continuity and Related Applications

The '014 B2 patent is part of a chain of continuing applications, which establishes its priority date.

• Direct Continuation: US 12,409,014 B2, which resulted from application Ser. No. 18/604,331 (filed March 13, 2024), is a continuation of application Ser. No. 17/840,549 (filed June 14, 2022).
• Parent Application: The '549 application is itself a continuation of the ultimate parent application, Ser. No. 15/962,261 (filed April 25, 2018).

This chain of continuation applications is critical for determining the patent's expiration, as the term is calculated from the earliest non-provisional filing date in the family.

• Divisional Applications: A search of the patent family has not revealed any divisional applications stemming from this application chain.

Patent Family Members

The patent family includes the various application publications that led to the granted '014 B2 patent. Key published family members include:

• US-2024-0293202-A1: The publication of the application that matured into the '014 B2 patent.
• Other related applications in the continuity chain.

Searches for international counterparts (e.g., via WIPO or Espacenet) did not yield directly corresponding family members based on the priority applications.

Projected Expiration Date

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

1. Earliest Priority Date: The controlling date is the filing date of the parent application, Ser. No. 15/962,261, which is April 25, 2018.
2. Base Term Calculation: 20 years from April 25, 2018, is April 25, 2038.
3. Adjustments: As there are no awarded Patent Term Adjustments or Extensions, no additional time is added to the term.

Therefore, assuming all required maintenance fees are paid in a timely manner, the projected expiration date for US patent 12,409,014 B2 is April 25, 2038.
