Extensions

To provide a detailed analysis of US patent 11347657 regarding its term adjustments, extensions, related applications, and projected expiration date, I need to access the official USPTO patent records directly. While I cannot perform a live, interactive search of the USPTO database like Patent Center (which requires specific login credentials and structured queries beyond my current capabilities), I can interpret the information usually found in such records based on the details already available within the patent document and general patent law principles.

Based on the information available and general patent practice:

Patent Term Adjustments (PTA)

Patent Term Adjustments (PTA) compensate patent owners for delays caused by the USPTO during the patent examination process. This typically includes delays if the USPTO fails to issue a first office action within 14 months of filing, fails to respond to a reply or an appeal within four months, or fails to issue a patent within three years of the application filing date. The total PTA is calculated at the time of patent issuance and is added to the standard 20-year patent term.

To determine the exact PTA for US11347657, one would need to consult the "Issue Notification Letter" that was mailed to the applicant approximately three weeks prior to the patent's issuance (May 31, 2022). This letter details the PTA calculation, including any deductions for applicant delays. Without direct access to this document or the Patent Center details for 11347657, I cannot provide the precise PTA.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are distinct from PTA and are granted under 35 U.S.C. § 156. They restore patent term lost due to delays in regulatory review for certain products, primarily human drugs, medical devices, food additives, and other specified products requiring premarket government approval.

There is no information within the provided patent text for US11347657 that indicates it claims a product subject to regulatory review that would qualify for a PTE. Therefore, it is highly unlikely that US11347657 has received or is eligible for a Patent Term Extension.

Continuation and Divisional Applications

The provided patent text explicitly states that US11347657 is a continuation of several earlier-filed applications:

• U.S. Utility patent application Ser. No. 16/808,304, filed on Mar. 3, 2020.
• U.S. Utility patent application Ser. No. 15/690,006, filed on Aug. 29, 2017 (issued as U.S. patent Ser. No. 10/642,748).
• U.S. Utility patent application Ser. No. 15/074,778, filed on Mar. 18, 2016 (issued as U.S. Pat. No. 9,785,572).
• U.S. Utility patent application Ser. No. 14/880,529, filed on Oct. 12, 2015 (issued as U.S. Pat. No. 9,542,118).
• U.S. Utility patent application Ser. No. 14/848,273, filed on Sep. 8, 2015.

These are all part of the patent's prosecution history, indicating a series of continuation applications. A "continuation application" is a second application for the same invention claimed in a prior nonprovisional application and filed while the prior application is still pending. A "divisional application" is a type of continuing application that claims subject matter disclosed in an earlier filed parent application but distinct from the claims of the parent application. The provided text indicates a chain of continuations, but does not explicitly mention divisional applications stemming from 11347657 itself.

Related Family Members

Based on the continuation chain provided, the following are direct related family members in the United States, sharing a common priority:

• US10642505B1 (issued May 5, 2020, from Ser. No. 15/690,006)
• US9785572B1 (issued Oct. 10, 2017, from Ser. No. 15/074,778)
• US9542118B1 (issued Jan. 10, 2017, from Ser. No. 14/880,529)

Additionally, several provisional applications contribute to the priority date:

• U.S. Provisional Patent Application No. 62/199,969, filed on Jul. 31, 2015.
• U.S. Provisional Patent Application No. 62/194,172, filed on Jul. 17, 2015.
• U.S. Provisional Patent Application No. 62/063,357, filed on Oct. 13, 2014.
• U.S. Provisional Patent Application No. 62/048,162, filed on Sep. 9, 2014.

These documents form the US patent family for the core inventive concepts. A "patent family" can refer to all patent documents in various countries related to a single invention, or more simply, all documents having at least one common priority.

Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally extends 20 years from the earliest filing date of the application, or if it claims priority to an earlier application, 20 years from the filing date of the earliest such application.

US11347657 claims priority from U.S. Provisional Patent Application No. 62/048,162, which was filed on September 9, 2014. This is the earliest priority date established in the patent's lineage.

Therefore, the base expiration date (before any Patent Term Adjustment) for US11347657 is 20 years from September 9, 2014, which is September 9, 2034.

However, as mentioned in the "Patent Term Adjustments" section, any PTA granted would be added to this 20-year term. The Google Patents record for US11347657B1 explicitly states an "Anticipated expiration" date of 2035-09-08. This indicates that approximately one year of Patent Term Adjustment was likely granted. This adjustment would move the expiration from September 9, 2034, to September 8, 2035. This difference between the calculated 20-year term and the "Anticipated expiration" suggests a PTA of approximately one year.
