Extensions

To provide accurate information regarding US Patent 11716171, including patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date, I need to access detailed information from the USPTO database.

Unfortunately, my current tools do not allow me to directly perform a live, authenticated search of the USPTO database or Patent Center for specific PTA/PTE calculations, or to retrieve a complete list of related applications with their specific designations (continuation, divisional, etc.). While I can perform general Google searches, these often lead to summary information or articles about how to find such details, rather than the raw data itself from the official USPTO records for a given patent.

The Google Patents record for US11716171 does provide some relevant information, such as:

• Filing Date: 2021-01-11 [cite: Filing date]
• Publication Date: 2023-08-01 [cite: Publication date]
• Adjusted expiration: 2036-07-28 [cite: Adjusted expiration]

Based on this, I can infer the following:

• Projected Expiration Date: The Google Patents record explicitly states an "Adjusted expiration" date of 2036-07-28 [cite: Adjusted expiration]. This date likely already incorporates any Patent Term Adjustments (PTA) that may have been granted. For utility patents filed on or after June 8, 1995, the basic patent term is 20 years from the earliest effective filing date. The original priority date for this patent is 2015-03-04 [cite: Priority date], and the filing date of the application that directly led to US11716171 is 2021-01-11 [cite: Filing date]. The fact that the expiration is listed as 2036-07-28 suggests a term calculation that is not a straightforward 20 years from the earliest priority or filing date, indicating the presence of adjustments.

Regarding Patent Term Adjustments (PTA):
PTA extends the term of a U.S. patent to compensate for certain delays caused by the USPTO during the prosecution of a utility or plant patent application. The USPTO automatically determines the PTA period and transmits a notice of this determination no later than the patent's issue date. The "Adjusted expiration" date of 2036-07-28 on the Google Patents record suggests that PTA has been applied and accounted for in this projected expiration.

Regarding Patent Term Extensions (PTE):
PTEs are available for patents covering pharmaceutical products, food or color additives, medical devices, animal drugs, and veterinary biological products to restore patent term lost while awaiting premarket government approval from a regulatory agency, such as the FDA. There is no information within the provided patent text or search results to indicate that US11716171 is related to such products or that a PTE application has been filed or granted.

Regarding Continuation and Divisional Applications, and Related Family Members:
The patent mentions priority to several Korean Patent Applications and a PCT application, as well as being a continuation of earlier U.S. patent applications:

• Continuation of U.S. patent application Ser. No. 16/377,829, filed Apr. 8, 2019 [cite: CROSS-REFERENCE TO RELATED PATENT APPLICATIONS]
• Which is a continuation of U.S. patent application Ser. No. 15/555,075, filed Jan. 2, 2018 [cite: CROSS-REFERENCE TO RELATED PATENT APPLICATIONS]
• Which is a U.S. National Stage Application under 35 U.S.C. §371 of PCT Application No. PCT/KR2016/002199, filed Mar. 4, 2016 [cite: CROSS-REFERENCE TO RELATED PATENT APPLICATIONS]
• Which claims priority to Korean Patent Application No's. 10-2015-0030369, filed Mar. 4, 2015, 10-2015-0036754, filed Mar. 17, 2015 and 10-2015-0066670, filed May 13, 2015 [cite: CROSS-REFERENCE TO RELATED PATENT APPLICATIONS].

A continuation application shares the same disclosure as its parent but pursues different claims, with no new subject matter added. A divisional application is filed when an examiner determines there is more than one invention in the scope of claims, and the applicant selects one invention to proceed with, while filing divisional applications for the unselected inventions. The provided text explicitly identifies this patent as a continuation application.

The Google Patents page also lists "Other versions" including US20210211236A1 [cite: Other versions]. This is a published patent application that is a family member. It also lists later priority dates:

• Priority to US18/209,079 (2023-06-13) [cite: 2023-06-13 Priority to US18/209,079]
• Priority to US18/911,756 (2024-10-10) [cite: 2024-10-10 Priority to US18/911,756]

To fully detail all related family members and definitively categorize them as continuations, divisionals, or continuation-in-part applications, direct access to the USPTO's Patent Center or Public Search with the ability to navigate the application's prosecution history would be required. However, based on the provided text, US11716171 is a continuation application stemming from a chain of prior applications, and it has other priority applications listed subsequent to its own filing date, indicating a complex family tree.
