Extensions

US Patent 10,516,775, titled "Method and system for communication," was issued on December 24, 2019, from an application filed on January 11, 2019. Here's a breakdown of its term adjustments, extensions, related applications, and projected expiration date based on available information:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can increase the term of a patent to compensate for certain delays by the USPTO during the prosecution of a utility or plant patent application. Such delays include failure to: issue a first Office Action within 14 months of filing; respond to an applicant's reply within 4 months; or issue the patent within 4 months of payment of the issue fee. The patent term can also be extended if the patent fails to issue within three years of its actual filing date. However, any extension can be reduced by delays caused by the applicant.

To get the exact PTA for US10516775, one would typically need to check the "Issue Notification Letter" which is mailed to applicants approximately three weeks before the patent issues, or access the patent's file history in USPTO's Patent Center. The USPTO does not calculate expiration dates for patents, but provides a calculator and guidelines for estimating them, which requires specific information from the patent's file.

Without direct access to the official USPTO Patent Center file history for US10516775 to confirm any granted PTA, it cannot be definitively stated here.

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 some of the patent term lost while awaiting premarket government approval from a regulatory agency like the FDA.

Given that US Patent 10,516,775 pertains to a "Method and system for communication" and not to a product requiring regulatory approval from agencies like the FDA, it is highly unlikely to be eligible for Patent Term Extension under 35 U.S.C. § 156.

Continuation and Divisional Applications

The patent text itself provides information regarding its lineage in the "CROSS REFERENCE" section. US10516775 is a continuation of several earlier applications:

• U.S. patent application Ser. No. 16/112,587, filed on August 24, 2018 (now U.S. Pat. No. 10,277,728).
• U.S. patent application Ser. No. 15/421,237, filed on January 31, 2017 (now U.S. Pat. No. 10,110,725).
• U.S. patent application Ser. No. 14/865,561, filed on September 25, 2015 (now U.S. Pat. No. 9,591,117).

This means US10516775 is a continuation application, claiming benefit from these earlier-filed nonprovisional applications. A continuation application is a follow-up application that discloses and claims only subject matter disclosed in a prior-filed, copending nonprovisional application, without introducing new matter.

The patent also claims the benefit of two provisional applications:

• U.S. provisional application No. 62/083,085 filed on November 21, 2014.
• U.S. provisional application No. 62/118,264 filed on February 19, 2015.

The term "divisional application" refers to an application for a distinct invention carved out of a prior, broader application. While the patent text mentions "continuation" specifically, it does not explicitly state that US10516775 is a divisional application. However, divisional applications are part of the broader family of continuing applications.

Related Family Members

Based on the cross-reference information, the identified family members are:

• US Patent 10,277,728 (parent of 10516775)
• US Patent 10,110,725 (parent of 10,277,728)
• US Patent 9,591,117 (parent of 10,110,725)
• U.S. provisional application No. 62/083,085
• U.S. provisional application No. 62/118,264

Additionally, the Google Patents information for US10516775 lists priority claims to subsequent applications, indicating further family members that are continuations or divisionals of US10516775:

• US17/150,786 (priority to 2021-01-15), which is US11316964B1
• US17/699,581 (priority to 2022-03-21), which is US11611649B2
• US19/303,950 (priority to 2025-08-19), which is US20250385966A1

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, excluding provisional applications, to which the patent claims priority.

US10516775 claims priority to U.S. patent application Ser. No. 14/865,561, filed on September 25, 2015, which itself claims the benefit of U.S. provisional application No. 62/083,085 filed on November 21, 2014. The earliest non-provisional filing date in the chain of applications for US10516775 is September 25, 2015 (from US14/865,561).

Therefore, the base patent term would be 20 years from September 25, 2015.
Base expiration date: September 25, 2015 + 20 years = September 25, 2035.

The Google Patents page for US10516775 also states an "Anticipated expiration" date of 2035-09-25. This confirms the calculation based on the earliest non-provisional filing date.

This projected expiration date does not include any potential Patent Term Adjustment (PTA) that might have been granted due to USPTO delays during prosecution. Without specific PTA data from the USPTO file wrapper, a precise adjusted expiration date cannot be determined, but the base term provides a strong estimate.
