Extensions

To provide the most accurate details regarding Patent Term Adjustments (PTA), Patent Term Extensions (PTE), continuation/divisional applications, and the projected expiration date for US patent 10812646, direct access to the USPTO's Patent Center or Public Patent Search tool would be ideal. The USPTO does not calculate expiration dates for patents but provides resources and calculators for estimation, as these calculations can be complex and involve various factors like the earliest effective filing date, PTA, PTE, and terminal disclaimers.

Based on the provided patent text and general knowledge of USPTO patent term rules:

1. Patent Term Adjustments (PTA):
PTA is granted to compensate for delays by the USPTO during patent prosecution, such as failing to issue an office action within 14 months, respond to a reply within four months, or issue a patent within 36 months of filing. The patent text for US10812646 does not explicitly state a PTA amount. To determine the exact PTA, one would typically examine the Issue Notification Letter or the patent's file history in Patent Center. However, a granted patent (like 10812646) would have its PTA calculated and displayed at the time of issuance.

2. Patent Term Extensions (PTE):
PTE is available for patents on certain products (human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products) to restore time lost during premarket government approval from regulatory agencies like the FDA. There is no indication within the provided information that US10812646 falls under these categories, which typically apply to pharmaceutical or medical device patents. Therefore, it is highly unlikely to have a PTE.

3. Continuation Applications, Divisional Applications, and Related Family Members:
US10812646 is part of a patent family. The provided patent text explicitly states:

• This application is a Continuation of U.S. patent application Ser. No. 16/370,233, filed on Mar. 29, 2019. [cite: The full patent text]
• U.S. patent application Ser. No. 16/370,233 is a Continuation of U.S. patent application Ser. No. 15/326,365, filed on Jan. 13, 2017, now U.S. patent Ser. No. 10/298,737, issued on May 21, 2019. [cite: The full patent text]
• U.S. patent application Ser. No. 15/326,365 is the U.S. National Phase under 35 U.S.C. § 371 of International Application No. PCT/JP2014/068826, filed on Jul. 15, 2014. [cite: The full patent text]

Additionally, the "Priority Applications" and "Applications Claiming Priority" sections indicate other related applications:

• Priority to US16/576,079 (which is US10812646 itself). [cite: The full patent text]
• Priority to US17/066,896 (patent/US11349977B2), filed 2020-10-09. [cite: The full patent text]
• Priority to US17/744,135 (patent/US11778084B2), filed 2022-05-13. [cite: The full patent text]
• Priority to US18/460,978 (patent/US12225153B2), filed 2023-09-05. [cite: The full patent text]

This indicates that US10812646 is part of a larger family of applications, with several continuations claiming priority back to the initial international filing. A divisional application is typically filed when the USPTO issues a restriction requirement, indicating that the original application contains more than one invention. The provided patent text does not specifically mention "divisional applications" in relation to US10812646.

4. Projected Expiration Date:
For U.S. utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest filing date of the application, or the earliest filing date to which priority is claimed.

The earliest priority date for US10812646 is 2014-07-15, from International Application No. PCT/JP2014/068826. [cite: The full patent text]
Therefore, the base 20-year term would typically run from this date.

• Base Expiration Date: July 15, 2014 + 20 years = July 15, 2034.

The patent text confirms this, stating the "Anticipated expiration" date as 2034-07-15. [cite: The full patent text] This expiration date already accounts for the 20-year term from the earliest priority date.

Any PTA granted would add to this base term. However, without direct access to the official PTA calculation from the USPTO for patent 10812646, it is not possible to provide a definitive adjusted expiration date. The "Anticipated expiration" date provided on the Google Patents page typically incorporates any PTA awarded. [cite: The full patent text] As such, the projected expiration date is July 15, 2034.
