Extensions

To provide comprehensive details on patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US Patent 10,624,575, a direct query to the USPTO Public Patent Application Information Retrieval (PAIR) system or a similar specialized patent database would be ideal. Since I do not have real-time access to such systems, I will rely on information typically found in a patent's front page data and general patent law principles.

Based on the information provided and general patent practice:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays by the USPTO during the prosecution of a patent application. These delays generally fall into three categories: "A delay" (USPTO failing to act within certain deadlines, e.g., issuing a first office action within 14 months of filing), "B delay" (application pending for more than three years), and "C delay" (delays due to interference, secrecy order, or successful appeal). Any PTA can be reduced by applicant-caused delays.

The provided patent text for US10624575 does not explicitly state the granted PTA. However, the Google Patents information for US10624575 shows an "Adjusted expiration" date of 2037-09-08. This "Adjusted expiration" date implies that PTA has been calculated and applied, as the standard 20-year term from the filing date (April 26, 2017) would be April 26, 2037. The difference between these dates (September 8, 2037, vs. April 26, 2037) represents the period of PTA.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents claiming products (e.g., human drugs, medical devices, food additives) that require regulatory approval before commercial marketing. This aims to restore patent term lost during the regulatory review process.

Given that US10624575 relates to "Monitoring sleep using microactivity states" and involves a "wearable device," it's plausible that it could be related to a medical device, which might be eligible for PTE. However, the patent text does not indicate that any PTE has been sought or granted. Eligibility for PTE requires specific conditions, including the patent claiming a product subject to regulatory review and the product being the first permitted commercial marketing. Without information about specific product approvals and related regulatory review periods, it's impossible to confirm if PTE has been applied or would be applicable to this patent.

Continuation and Divisional Applications

• Continuation Application: A continuation application is filed for the same invention disclosed in a prior, co-pending nonprovisional application, and its disclosure must not introduce new matter. It allows the applicant to pursue new claims after the parent application has been prosecuted.
• Divisional Application: A divisional application is a type of continuing application that results from an earlier application (the "parent" application) that claimed more than one independent and distinct invention. If the USPTO issues a restriction requirement, the applicant can elect one invention to prosecute in the parent application and file divisional applications for the non-elected inventions.

The provided patent text states that US10624575 is a "continuation-in-part of International Application No. PCT/CN2016/109624, filed on Dec. 13, 2016, which claims priority to Chinese Patent Application No. 201510939058.7, filed on Dec. 14, 2015." A "continuation-in-part" application typically includes new matter in addition to the subject matter of the parent application. The Google Patents information also lists "US20170224275A1" as "Other versions", which is the publication of the application that led to US10624575.

This indicates that US10624575 itself is a continuation-in-part of a PCT application. There is no information within the provided text to suggest that further continuation or divisional applications have been filed from US10624575.

Related Family Members

The patent text explicitly identifies the following related family members:

• International Application No. PCT/CN2016/109624, filed on December 13, 2016.
• Chinese Patent Application No. 201510939058.7, filed on December 14, 2015 (priority claim).
• US20170224275A1: This is the U.S. patent application publication corresponding to the application that matured into US10624575B2.

These represent the immediate family members directly referenced in the patent or its associated Google Patents entry.

Projected Expiration Date

The standard patent term for utility patents filed on or after June 8, 1995, is 20 years from the earliest claimed non-provisional filing date.

For US10624575, the filing date is April 26, 2017. However, the patent also claims priority to the PCT application filed on December 13, 2016, and the Chinese application filed on December 14, 2015. The 20-year term is typically calculated from the earliest non-provisional filing date for which a benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 386(c). In this case, the earliest effective filing date would likely be derived from the PCT application (December 13, 2016).

20 years from December 13, 2016, would be December 13, 2036.

However, the Google Patents listing explicitly states the "Adjusted expiration" date as 2037-09-08. This date already incorporates any Patent Term Adjustments (PTA) that were granted due to USPTO delays during prosecution. Therefore, the projected expiration date for US Patent 10,624,575 is September 8, 2037.
