Extensions — US Patent 11856414

To provide a comprehensive analysis of US patent 11856414, including patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date, I will use the information available and clarify what cannot be definitively determined without direct USPTO database access.

US Patent 11856414: Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers

Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) can add time to a patent's term to compensate for certain delays by the USPTO during prosecution, such as failing to issue a first Office Action within 14 months of filing, failing to respond to an applicant's reply within 4 months, or failing to issue the patent within 4 months of the issue fee payment. The PTA calculation is typically performed by the USPTO at the time of patent issuance and is included in the Issue Notification Letter. While the provided patent abstract and summary do not explicitly state the PTA amount for US11856414, a direct lookup on the USPTO's Patent Center for the patent number would provide this specific detail.

Patent Term Extensions (PTE):
Patent Term Extensions (PTE) are granted under 35 U.S.C. § 156 for patents on certain products, primarily human drugs, food/color additives, medical devices, animal drugs, and veterinary biological products, to restore patent term lost during premarket regulatory review by agencies like the FDA. Given the title and subject matter of US11856414 ("Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers"), it is highly unlikely to be eligible for PTE, as it does not appear to cover a product requiring premarket government approval.

Continuation Applications:
US11856414 is explicitly identified as a "continuation of U.S. patent application Ser. No. 17/468,509 filed Sep. 7, 2021" This demonstrates a direct continuation relationship.
The patent family information lists US17/468,509 as a parent application, which itself is a continuation of earlier applications.

Divisional Applications:
The provided text does not explicitly mention any divisional applications directly stemming from US11856414. A divisional application arises when a parent application contains claims to more than one invention, and the applicant files a new application for the non-elected invention(s).

Related Family Members:
US11856414 belongs to a patent family with a priority date of October 30, 2013. The family includes several applications and issued patents, indicating a strategy of continuing prosecution and potentially broadening or refining claims over time.
The "Applications Claiming Priority" section lists the following family members, all sharing the priority date of 2013-10-30:

US14/526,799 (now US10034179B2)
US16/039,660 (now US11115834B2)
US17/468,509 (now US11818591B2) (This is the direct parent of US11856414)
US18/447,597 (US11856414B1 itself)

Projected Expiration Date:
The anticipated expiration date listed on Google Patents for US11856414B1 is October 29, 2034.

It's important to note that patent terms typically last 20 years from the earliest non-provisional filing date to which they claim priority. The priority date for this patent family is October 30, 2013. A straightforward 20-year calculation from this date would suggest an expiration around October 30, 2033. The listed "Anticipated expiration" of October 29, 2034, suggests that approximately one year of Patent Term Adjustment (PTA) has been granted. This aligns with the concept of PTA compensating for USPTO delays.
