Extensions

To detail the patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and the projected expiration date for US patent 11687971, a direct search of the USPTO database for the specific patent number is required. The provided search results offer general information about these terms but do not contain the specific data for US11687971.

As of April 26, 2026, without direct access to the specific USPTO record for US11687971, I cannot confidently provide the precise details regarding its patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, or its exact projected expiration date.

General information regarding these topics is available:

• Patent Term Adjustment (PTA): PTA compensates patent applicants for certain administrative delays by the USPTO during prosecution of a utility or plant patent application. It adds to the 20-year lifespan of the patent. Delays such as the USPTO failing to issue a first office action within 14 months, respond to an applicant's reply within four months, or issue a patent within 36 months of the filing date can lead to PTA.
• Patent Term Extension (PTE): PTE is granted to patents on certain products (e.g., human drugs, medical devices) to restore patent term lost due to the time spent awaiting premarket government approval from a regulatory agency like the FDA. An application for PTE must be filed within 60 days of regulatory agency approval of commercial marketing.
• Continuation and Divisional Applications: These are "continuing" applications filed during the pendency of a prior application, sharing at least part of the disclosure and a common inventor. A continuation application claims the same invention as an earlier application, while a divisional application claims a distinct invention disclosed but not claimed in the parent, often filed in response to a restriction requirement. Both are generally entitled to the parent's priority date.
• Patent Family Members: These include continuation, divisional, and continuation-in-part (CIP) applications that stem from an earlier-filed application.

To obtain the specific information for US11687971, one would typically use the USPTO's Patent Public Search tool or Patent Center. Without performing a live search on these platforms, the requested details cannot be provided with certainty.
