Extensions

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and the projected expiration date for US Patent 12303166, I will use the information available from Google Patents and general USPTO rules regarding patent term. The current date is April 26, 2026.

Based on the information, here's a detailed breakdown:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. It adds days to the 20-year term from the earliest non-provisional filing date. The USPTO automatically determines PTA and provides a notice of this determination by the patent's issue date.

The Google Patents page for US12303166 indicates a filing date of 2024-07-19 and a publication date (and grant date) of 2025-05-20. The time from filing to grant is less than one year, specifically about 10 months. While the patent was granted on May 20, 2025, the Google Patents page currently does not display a specific PTA amount. To get the precise PTA, one would typically need to check the official USPTO Patent Center for the patent's full prosecution history and the PTA calculation. However, given the relatively short pendency period from filing to issuance (less than 36 months, which is a key benchmark for B-delay PTA), it's possible the PTA would be minimal or none, assuming the USPTO met its other statutory deadlines (e.g., issuing a first office action within 14 months, responding to replies within 4 months).

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents claiming products (human drugs, food/color additives, medical devices, animal drugs, and veterinary biological products) that require regulatory approval, to compensate for time lost during the regulatory review process. The application for PTE must be filed within 60 days of the marketing approval date.

Given that US12303166 relates to medical methods and devices for accessing nerves within bone, particularly for basivertebral nerve (BVN) ablation, it falls into the category of patents potentially eligible for PTE due to regulatory review by agencies like the FDA. However, the provided patent information and Google Patents page for US12303166 do not indicate that an application for PTE has been filed or granted. Without this information from the USPTO or FDA records, it cannot be confirmed whether a PTE has been applied to this patent.

Continuation and Divisional Applications

The patent text itself indicates that "This application is a continuation of U.S. patent application Ser. No. 16/368,453, filed on Mar. 28, 2019, which is a continuation of U.S. patent application Ser. No. 15/040,268, filed on Feb. 10, 2016, issued as U.S. Pat. No. 10,265,099, which is a continuation of U.S. patent application Ser. No. 13/862,242 filed on Apr. 12, 2013, issued as U.S. Pat. No. 9,259,241, which is a continuation of U.S. patent application Ser. No. 12/566,895 filed on Sep. 25, 2009, issued as U.S. Pat. No. 8,419,730, which claims the benefit of U.S. Provisional Application 61/100,553 filed on Sep. 26, 2008." This establishes a clear chain of continuation applications.

• Provisional Application: US Provisional Application 61/100,553 filed on Sep. 26, 2008.
• Non-Provisional Applications (Continuation Chain):
  1. U.S. patent application Ser. No. 12/566,895 filed on Sep. 25, 2009, issued as U.S. Pat. No. 8,419,730.
  2. U.S. patent application Ser. No. 13/862,242 filed on Apr. 12, 2013, issued as U.S. Pat. No. 9,259,241.
  3. U.S. patent application Ser. No. 15/040,268, filed on Feb. 10, 2016, issued as U.S. Pat. No. 10,265,099.
  4. U.S. patent application Ser. No. 16/368,453, filed on Mar. 28, 2019.
  5. US18/778,387 (the application for US12303166B2), filed on 2024-07-19.

No specific divisional applications are explicitly mentioned for US12303166 in the provided text. Divisional applications arise when an original application claims two or more independent and distinct inventions, and the USPTO requires restriction to one invention, with the other invention forming the basis of a new, "divisional" application.

Related Family Members

The related family members are those identified in the continuation chain:

• US Provisional Application 61/100,553
• US Pat. No. 8,419,730
• US Pat. No. 9,259,241
• US Pat. No. 10,265,099
• U.S. patent application Ser. No. 16/368,453
• US20240366265A1 (publication of US18/778,387)
• US20250275787A1 (priority to US19/212,313)
• US20260076715A1 (priority to US19/399,248)

These form a patent family stemming from the initial provisional application.

Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest non-provisional filing date, with any PTA added to this term. US12303166 claims benefit from a chain of applications going back to a provisional application filed on September 26, 2008. The earliest non-provisional application in this chain is U.S. patent application Ser. No. 12/566,895, filed on September 25, 2009.

Therefore, the base patent term is 20 years from September 25, 2009.
Base expiration date: September 25, 2009 + 20 years = September 25, 2029.

The Google Patents page explicitly lists "Anticipated expiration: 2029-09-25". This date is consistent with the 20-year term from the earliest non-provisional filing date in its priority chain, assuming no significant PTA or PTE. As noted earlier, the specific PTA is not provided in the readily available Google Patents data, and no PTE is explicitly mentioned. Therefore, based on the current information, the projected expiration date is September 25, 2029.
