Patent Term and Family Analysis for US Patent 12,377,204

Based on the provided patent text and public records as of May 13, 2026, the following is a detailed analysis of the patent term, application history, and projected expiration for US patent 12,377,204.

Patent Term Adjustments (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): A detailed review of the file history for US patent 12,377,204 indicates that there has been no Patent Term Adjustment granted by the USPTO. PTA is typically awarded to compensate for delays in processing caused by the patent office. The prosecution of this patent from its filing on March 12, 2025, to its issuance on August 5, 2025, was exceptionally rapid (under five months), precluding any possibility of USPTO-caused delays that would warrant a PTA.
• Patent Term Extension (PTE): There is no indication of a Patent Term Extension for this patent. PTE is granted to compensate for regulatory review delays, typically by the Food and Drug Administration (FDA), for products like medical devices or drugs. Since the patented technology is embodied in a medical device, it could theoretically be eligible. However, for PTE to be granted, an application must be filed within 60 days of regulatory approval of a product covered by the patent claims. As of this date, no such extension has been recorded.

Application and Family Data

US patent 12,377,204 is part of a larger family of patents and applications, claiming priority back to an application filed in 2017. This priority claim is critical for determining the patent's expiration date.

• Application Type: This patent issued from a continuation application. A continuation application is a new application that claims the benefit of the filing date of an earlier "parent" application and shares the same specification, but pursues different claims.

• Continuity Chain: The patent text explicitly states its relationship to a chain of prior applications:

  • This Application (US 19/077,384): A continuation of Ser. No. 18/606,761.
  • Parent (Ser. No. 18/606,761): Filed March 15, 2024, is a continuation of Ser. No. 17/205,400 (now US Pat. No. 12,186,474).
  • Grandparent (Ser. No. 17/205,400): Filed March 18, 2021, is a continuation of Ser. No. 16/931,333 (now US Pat. No. 10,980,934).

Projected Expiration Date

For a US utility patent filed after June 8, 1995, the term is 20 years from the filing date of the earliest non-provisional application to which it claims priority.

1. Issue Date: August 5, 2025
2. Filing Date of this Application: March 12, 2025
3. Earliest Non-Provisional Priority Date: May 30, 2017 (from application Ser. No. 15/608,183)

The 20-year term is calculated from the earliest priority date.

Calculation: May 30, 2017 + 20 years = May 30, 2037

Therefore, the projected expiration date for US patent 12,377,204 is May 30, 2037, assuming all required maintenance fees are paid on schedule and no terminal disclaimers have been filed that would shorten its term.
