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 10,874,304, I would typically access the Public PAIR or Patent Center system on the USPTO website. However, since I cannot directly access those live systems, I will rely on the provided patent text and general knowledge about how these terms are applied.

Based on the provided patent text and general USPTO rules:

Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. The patent document itself does not explicitly state the PTA amount. This information is usually found on the issue notification or in the patent's file wrapper in Patent Center. Without direct access to the USPTO's official patent records for US10874304, the precise PTA cannot be determined.

Patent Term Extensions (PTE):
Patent Term Extensions (PTE) are available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost during premarket government approval from a regulatory agency. The patent, US10874304, is related to a "Semiconductor source based near infrared measurement device," which could potentially fall under the "medical devices" category. However, the provided text does not indicate whether a PTE application has been filed or granted for this patent. Such information would typically be found in the patent's image file or in the USPTO's lists of PTE applications and granted extensions.

Continuation and Divisional Applications, and Related Family Members:
The patent text explicitly states its lineage, indicating it is part of a larger family of applications:
"U.S. application Ser. No. 16/506,885 is also a continuation of U.S. application Ser. No. 16/188,194 filed Nov. 12, 2018 (now U.S. Pat.

It also lists other related applications:

No. 9,651,533), which is a continuation of U.S. application Ser. No. 14/109,007 filed Dec. 17, 2013."

From the provided text, the earliest priority date mentioned is December 17, 2013, derived from U.S. application Ser. No. 14/109,007.

Projected Expiration Date:
For U.S. utility patents filed on or after June 8, 1995, the patent term is generally 20 years from the earliest filing date of the patent application, or the earliest application to which priority is claimed under 35 U.S.C. §§ 120, 121, or 365(c). This 20-year term can be adjusted by PTA or extended by PTE.

The earliest priority date mentioned in the patent text is December 17, 2013, for U.S. application Ser. No. 14/109,007. Therefore, the base expiration date (before any adjustments or extensions) would be 20 years from this date.

Base Expiration Date = December 17, 2013 + 20 years = December 17, 2033.

The Google Patents page itself lists "Anticipated expiration: 2033-12-17" under its legal status section, which aligns with the 20-year term from the earliest priority date. This date does not appear to include any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE), as those would typically extend the term beyond the 20-year anniversary of the earliest priority date. Since the patent was issued on December 29, 2020, and the filing date of the application (US16/669,794) was October 31, 2019, there could be PTA granted due to USPTO delays in examination or issuance. However, the precise PTA amount would need to be confirmed by reviewing the official USPTO file history in Patent Center.

Therefore, the projected expiration date listed on Google Patents is December 17, 2033. This date is based on the 20-year term from the earliest priority claim, without accounting for potential PTA or PTE. [cite: "Anticipated expiration 2033-12-17"]
