Extensions

To provide a comprehensive detail for US Patent 12427372, I need to consult the official USPTO Patent Center or Public Search tools, which directly provide information on prosecution history, including any PTA, PTE, and related applications. My current access is limited to general search results and the information previously provided about the patent from Google Patents.

Based on the available information:

• Patent Term Adjustments (PTA): The USPTO automatically determines and transmits a notice of any PTA on or before the date of patent issuance. PTA extends the patent term to compensate for certain delays caused by the USPTO during prosecution, such as failing to issue an office action within 14 months of filing, responding to a reply within four months, or issuing a patent within 36 months of the filing date. Since US12427372 was granted on 2025-09-30, the PTA would have been calculated and notified at that time. Without direct access to the patent's full prosecution history on the USPTO Patent Center, the specific PTA for US12427372 cannot be determined here.
• Patent Term Extensions (PTE): PTEs are granted for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost due to premarket government approval from a regulatory agency like the FDA. Given that US12427372 is for a "leg training device," it is highly unlikely to be eligible for a PTE, as it does not fall into the categories of products requiring regulatory approval under 35 U.S.C. § 156.
• Continuation Applications: A continuation application allows an applicant to pursue more patent claims from an earlier "parent" application while retaining the earlier priority date. These must be filed before the parent application issues or becomes abandoned. The provided patent information for US12427372 does not explicitly list any continuation applications. However, new USPTO fees for continuation applications were implemented in 2025, applying to applications filed six or more years after their earliest benefit date, with higher fees for those filed nine or more years after.
• Divisional Applications: A divisional application is filed when an examiner determines that a single patent application contains two or more patentable inventions and issues a restriction requirement. The applicant can then choose one invention to pursue in the parent application and file divisional applications for the non-elected inventions, also retaining the priority date of the original application. The provided patent information for US12427372 does not explicitly list any divisional applications.
• Related Family Members: The Google Patents page for US12427372 lists "US20250082992A1" as another version and a publication. This indicates that US20250082992A1 is a published patent application that corresponds to the granted patent US12427372B2. The application number is US18/955,928 [cite: Publication number: US12427372B2, Other versions: US20250082992A1, Application number: US18/955,928].
• Projected Expiration Date: The default term for a U.S. utility patent is 20 years from its earliest effective filing date, not including any provisional applications. US12427372 has a filing date of 2024-11-21 [cite: Filing date: 2024-11-21]. Therefore, without any PTA, the anticipated expiration date would be 20 years from the filing date, which is 2044-11-21. Google Patents also lists this as the "Anticipated expiration" date [cite: Anticipated expiration: 2044-11-21]. If there were any PTA, this date would be later. As noted above, a specific PTA amount is not available from the provided data.
