Extensions

To provide a comprehensive analysis of US Patent 10379301, including patent term adjustments, extensions, related applications, and the projected expiration date, a direct search of the USPTO's Patent Center or Public Pair database would be ideal. Since direct access to these systems is not available, the information will be extracted from the Google Patents entry and augmented by general knowledge of patent law and search results.

US Patent 10379301:

• Filing Date: February 14, 2017 [cite: US10379301B2]
• Issue Date: August 13, 2019 [cite: US10379301B2]

Patent Term Adjustment (PTA)

Patent Term Adjustment (PTA) is granted to compensate patent applicants for certain delays incurred by the USPTO during the prosecution of a patent application. This adjustment is added to the standard 20-year patent term.

The Google Patents legal status for US10379301 does not explicitly list a calculated PTA amount. However, the "Anticipated expiration" date is listed as February 14, 2037 [cite: US10379301B2].
The standard patent term is 20 years from the earliest effective filing date. For US10379301, the filing date is February 14, 2017. Twenty years from this date would be February 14, 2037. Since the "Anticipated expiration" date matches this 20-year period, it implies that no Patent Term Adjustment was applied, or any potential adjustment was offset by applicant delays. [cite: US10379301B2]

Patent Term Extension (PTE)

Patent Term Extension (PTE) is typically available for patents covering pharmaceutical products that undergo lengthy FDA approval processes. This provision is governed by 35 U.S.C. § 156.

Given that US10379301 pertains to a "Multi-channel parallel optical receiving device" and is not related to a pharmaceutical product, it is highly unlikely to have received any Patent Term Extension (PTE).

Continuation Applications and Divisional Applications

• Continuation Application: A continuation application is a second application for the same invention claimed in a prior, co-pending parent application, typically filed to pursue rejected claims or a different scope of claims based on the exact same disclosure. A continuation application cannot contain any new subject matter.
• Divisional Application: A divisional application claims a distinct invention disclosed but not claimed in a parent application, filed in response to a USPTO restriction requirement. It also claims the benefit of the parent's filing date.

The Google Patents entry for US10379301 lists "Applications Claiming Priority (2)" and "Family Applications (1)". [cite: US10379301B2]

The following applications claim priority from the same priority date (2016-05-23) as US10379301 or are otherwise related:

• US15/432,242: This is the application number for US10379301 itself. [cite: US10379301B2]
• US20170336582A1: This is a publication of US15/432,242. [cite: US10379301B2]
• CN201610346007.8A / CN105866904A: This is a Chinese patent application/publication with the same priority date (2016-05-23). [cite: US10379301B2]
• CN2016103460078: Another Chinese application with the same priority date. [cite: US10379301B2]
• TW105135616A / TWI616695B: This is a Taiwanese patent application/publication, also sharing the same priority date. [cite: US10379301B2]

Based on the provided information, US10379301 (application US15/432,242) does not appear to be a continuation or divisional of an earlier U.S. patent application itself. It claims priority to an earlier foreign priority date (2016-05-23). The "Family Applications" section lists only US15/432,242 [cite: US10379301B2].

However, the "Publications" section lists US20170336582A1 as a publication of US15/432,242 [cite: US10379301B2]. This indicates that US15/432,242 was the original non-provisional application from which US10379301 issued. There are no other US applications listed under "Applications Claiming Priority" or "Family Applications" that would suggest US10379301 is a child of an earlier US application. If there were continuation or divisional applications, they would typically be listed with their own application numbers and their relationship to the parent. The USPTO assigns new application numbers to continuation or divisional applications.

Related Family Members

The patent family refers to a group of patent applications and patents that protect the same invention in different countries or through different types of applications.

The family for US10379301 (Family ID=56635726) includes:

• US15/432,242 (US10379301B2): The U.S. patent itself. [cite: US10379301B2]
• CN201610346007.8A (CN105866904A): A Chinese patent application/publication. [cite: US10379301B2]
• TW105135616A (TWI616695B): A Taiwanese patent application/publication. [cite: US10379301B2]

These are considered national counterparts or related applications stemming from the same priority date, protecting the same underlying invention in different jurisdictions.

Projected Expiration Date

The "Anticipated expiration" date for US10379301 is listed as February 14, 2037 [cite: US10379301B2].

This date is calculated as 20 years from the filing date of the application (February 14, 2017). As discussed in the PTA section, the absence of an explicitly stated PTA or a later expiration date suggests that no PTA was awarded, or any award was negated by applicant delays. Therefore, the patent is currently projected to expire on this date, barring any future events such as terminal disclaimers (which are not indicated) or successful requests for reconsideration of PTA.
