Analysis of U.S. Patent 12,236,947

Date of Analysis: May 8, 2026

Based on the file history and data associated with U.S. Patent 12,236,947, the following is a detailed breakdown of its term, application history, and related family members.

Patent Term Adjustment (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): A formal Patent Term Adjustment is calculated by the USPTO upon issuance to compensate for administrative delays during prosecution. This calculation is complex and depends on specific deadlines for office actions and applicant responses. The provided documentation for US 12,236,947 does not specify the exact number of PTA days granted. This information would typically be available on the front page of the issued patent or through the USPTO's Patent Center portal by reviewing the complete file wrapper. Without this specific data, a precise PTA calculation cannot be made.
• Patent Term Extension (PTE): There is no indication that this patent is eligible for or has been granted a Patent Term Extension. PTE is typically associated with delays in regulatory review for products like pharmaceuticals and is not applicable to this technology area.

Continuity and Family Data

• Continuation Applications: US Patent 12,236,947, which stems from application number US 18/219,906, is a continuation of a prior application. As stated in the patent's description, "This application is a continuation of U.S. application Ser. No. 17/239,894, filed on Apr. 26, 2021".
• Divisional Applications: The prosecution history does not indicate that any divisional applications have been filed from this patent's lineage.
• Patent Family Members: This patent is part of a family of two related U.S. patents. The relationship is as follows:
  • Parent Application: U.S. Application No. 17/239,894, filed on April 26, 2021. This application subsequently issued as U.S. Patent No. 11,735,172 B2 on August 22, 2023.
  • Child Application (Continuation): U.S. Application No. 18/219,906, filed on July 10, 2023. This is the application that matured into the patent under review, U.S. Patent No. 12,236,947 B2.

Projected Expiration Date

The term of a U.S. patent is twenty years from the filing date of the earliest U.S. non-provisional application to which it claims priority. In this case, the earliest effective filing date is that of the parent application (US 17/239,894), which is April 26, 2021.

Therefore, the base expiration date is calculated as:
April 26, 2021 + 20 Years = April 26, 2041.

This projected expiration date is also noted in the legal status information for the patent. It must be emphasized that this date does not include any Patent Term Adjustment (PTA) that may have been granted by the USPTO. Any awarded PTA would be added to this base expiration date, potentially extending the patent's term. The final expiration date can only be confirmed by accessing the official PTA calculation from the USPTO.
