Extensions

To determine the specifics of US patent 12539795, including patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date, I will refer to the patent document itself and USPTO guidelines.

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE):
The provided patent text does not explicitly state any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) that were granted for US12539795. PTA is granted to compensate for certain delays in patent prosecution by the USPTO, while PTE is granted for delays due to regulatory review processes, particularly for drugs and medical devices. Since US12539795 is for a "Personal transportation vehicle," it is unlikely to qualify for PTE. To definitively determine PTA, one would typically need to consult the "Patent Term Adjustment" section in the official USPTO patent record (e.g., in Public PAIR or Patent Center).

Continuation Applications, Divisional Applications, and Related Family Members:
US12539795 is part of a patent family, as indicated by its "Related Applications" section. It explicitly states:
"The present application claims priority to and is a continuation of U.S. patent application Ser. No. 18/390,811, filed on Dec. 20, 2023, which is a continuation of U.S. patent application Ser. No. 17/173,506, filed on Feb. 11, 2021, now issued as U.S. Pat. No. 11,884,191, which is a continuation of U.S. patent application Ser. No. 15/872,678, filed on Jan. 16, 2018, now issued as U.S. Pat. No. 10,940,780."

Therefore, the following are related family members:

• US Patent 10,940,780 (Parent application: Ser. No. 15/872,678, filed Jan. 16, 2018)
• US Patent 11,884,191 (Parent application: Ser. No. 17/173,506, filed Feb. 11, 2021)
• US Patent 12,246,630 (Parent application: Ser. No. 18/390,811, filed Dec. 20, 2023)
• US Patent 12,539,795 (Current patent, a continuation of Ser. No. 18/390,811, filed Feb. 7, 2025)

The patent explicitly identifies itself as a continuation application. There is no mention of divisional applications in the provided text.

Projected Expiration Date:
For U.S. patents (other than design patents) issued from applications filed on or after June 8, 1995, the patent term generally ends 20 years from the earliest filing date for which a benefit is claimed under 35 U.S.C. §§ 120, 121, or 365(c).

In this case, US12539795 claims priority back to U.S. patent application Ser. No. 15/872,678, which was filed on January 16, 2018.

Therefore, the standard 20-year patent term would expire on January 16, 2038.

However, this calculation does not account for any potential Patent Term Adjustments (PTA) that might have been awarded. While the patent itself does not specify PTA, the "Legal status" section on Google Patents states an "Anticipated expiration" of 2038-01-16. This suggests that no PTA was awarded or, if awarded, it did not extend the term beyond the standard 20 years from the earliest priority date.

It is important to note that the actual expiration date can be affected by factors such as terminal disclaimers or maintenance fee payments. Without access to the full prosecution history from the USPTO Patent Center, this remains the projected expiration date based on the earliest priority claim and the provided summary.
