Extensions

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date for US Patent 11668420, I will use the information available from the provided patent text and the USPTO's public resources.

Patent Term Adjustments (PTA)

Patent Term Adjustments (PTA) are awarded to compensate patent applicants for certain delays incurred during the prosecution of a patent application by the USPTO. The PTA amount is usually noted on the face of the issued patent.

The provided patent text for US11668420B2 does not explicitly state a specific number of days for Patent Term Adjustment on its front page. However, it notes the legal status as "Active, expires 2039-12-27". Since the original priority date is 2019-12-27, and a utility patent typically has a term of 20 years from its earliest filing date, the unadjusted expiration date would be 2039-12-27. The fact that the "adjusted expiration" is listed as 2039-12-27 suggests that either no PTA was awarded, or any awarded PTA was offset by applicant delay, resulting in no net adjustment to the 20-year term from the priority date. Without a specific PTA value mentioned in the document, it is not possible to confirm the exact adjustment.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents covering certain products (e.g., human drugs, medical devices) that require regulatory approval before commercial marketing, to compensate for time lost during the regulatory review process.

Based on the nature of the invention (hydraulic fracturing system), US Patent 11668420 does not appear to be eligible for Patent Term Extension under 35 U.S.C. § 156, as it does not relate to pharmaceutical products, food additives, medical devices, or veterinary biological products. Therefore, it is highly unlikely to have received any PTE.

Continuation Applications, Divisional Applications, and Related Family Members

The patent text provides a "Priority Applications" section and "Applications Claiming Priority" section, as well as "Related Parent Applications" and "Related Child Applications" and a "Family" section. These sections help identify continuation, divisional, and related family members.

From the provided text:

• Continuation Applications: US11668420B2 itself is a continuation of U.S. patent application Ser. No. 16/728,359 filed Dec. 27, 2019.
• Related Child Applications: US18/206,313 is listed as a continuation of US11668420B2, with a filing date of 2023-06-06 and identified as US12152711B2.
• Divisional Applications: No specific divisional applications are explicitly mentioned in the provided text.
• Related Family Members: The "Family" section shows the following applications as part of the same family (Family ID=75910393):
  • US16/728,359 (US11009162B1) - Priority Date: 2019-12-27, Filing Date: 2019-12-27.
  • US17/321,936 (US11668420B2) - Priority Date: 2019-12-27, Filing Date: 2021-05-17.
  • US18/206,313 (US12152711B2) - Priority Date: 2019-12-27, Filing Date: 2023-06-06.
  • The family also includes international equivalents, such as AR120897A1.

Projected Expiration Date

The "Legal status" section of the Google Patents information for US11668420B2 explicitly states: "Active, expires 2039-12-27".

This expiration date is consistent with a 20-year patent term from the earliest priority date of 2019-12-27 (which corresponds to US application Ser. No. 16/728,359). As noted in the PTA section, the "Adjusted expiration" date being the same as the unadjusted 20-year term from the priority date suggests no net PTA was applied to extend the patent's life.
