Prosecution History and Patent Term

This section details the prosecution history, related applications, and patent term for U.S. Patent No. 12347711.

Patent Term Adjustments (PTA) / Patent Term Extensions (PTE):

A review of the bibliographic data for US patent 12347711 indicates an "Adjusted expiration" date of May 16, 2043. The standard 20-year term from the earliest non-provisional priority date of August 17, 2021, would typically result in an expiration date of August 17, 2041. The listed adjusted expiration date suggests a significant patent term adjustment was granted by the USPTO, likely to compensate for delays during the patent's prosecution. The provided data does not specify the exact number of PTA days granted, but the difference between the standard and adjusted dates indicates a substantial adjustment. There is no information indicating any patent term extension (PTE) under 35 U.S.C. § 156, which is typically granted for regulatory review delays and is uncommon for this type of technology.

Continuation and Divisional Applications:

The bibliographic data shows that US patent 12347711 claims priority to a chain of applications. Notably, it claims priority to application US17/882,703, filed on August 8, 2022.

This indicates that the patent is part of a continuing prosecution strategy by the applicant to pursue different sets of claims based on the original disclosure. US18/918,311 is a continuation of the application that led to this patent. (Source: https://patents.google.com/patent/[US12347711](/patent/US12347711)/en)
