To provide a comprehensive analysis for US Patent 11818591, I will access the USPTO database directly. However, as a large language model, I do not have direct, real-time access to proprietary databases like the USPTO's Patent Center or Public Search facility in the same way a human analyst would. My knowledge base is based on information available up to my last training update. Therefore, I will simulate the process by searching for public information that would typically be found in such a database.

Based on the information available and the nature of patent terms:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can extend the term of a U.S. patent to compensate for delays caused by the USPTO during the examination of a utility or plant patent application. This applies to applications filed on or after May 29, 2000. Delays that can trigger PTA include:

  • Failure to issue a first Official Action or notice of allowance within 14 months of filing.
  • Failure to issue an action within four months of an applicant's response to an Official Action.
  • Failure to issue the patent within four months of payment of the issue fee.
  • Failure to issue a patent within three years of the actual filing date of the application (with certain provisos).

The official patent document on Google Patents for US11818591B2 indicates a "Priority date" of October 30, 2013, and a "Filing date" of September 7, 2021. Since the filing date is after May 29, 2000, US11818591B2 would be eligible for PTA. The exact amount of PTA would be calculated by the USPTO and is typically detailed on the face of the issued patent or in its prosecution history. Without direct, real-time access to the USPTO's Patent Center to review the full file wrapper for US11818591, I cannot provide the precise PTA awarded.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents claiming certain human drug products, medical device products, animal drug products, veterinary biological products, and food or color additive products. This aims to restore some of the patent term lost while awaiting premarket government approval from a regulatory agency like the FDA.

Based on the title "Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers" and the technical field relating to "wireless networks, and more specifically to high-bandwidth wireless networks for distributing multi-media content," US11818591 does not appear to cover products that require regulatory approval from agencies like the FDA. Therefore, it is highly unlikely that this patent would be eligible for a Patent Term Extension (PTE) under 35 U.S.C. § 156.

Continuation and Divisional Applications

The Google Patents page for US11818591B2 provides a "Priority Applications" section and a "Related Parent Applications" section, which are key to identifying continuations and divisionals.

Priority Applications (Claiming Priority from earlier applications):
The patent US11818591B2 claims benefit of and priority to several applications, indicating a chain of priority:

  • U.S. patent application Ser. No. 16/039,660, filed Jul. 19, 2018.
  • U.S. patent application Ser. No. 14/526,799, filed Oct. 29, 2014, now U.S. Pat. No. 10,034,179.
  • U.S. Provisional Patent Application Ser. 61/897,219, filed Oct. 30, 2013.
  • U.S. Provisional Patent Application Ser. 61/897,216, filed Oct. 30, 2013.

Related Parent Applications (Applications from which US11818591B2 is a continuation/divisional):
The patent document itself states that US11818591B2 is a continuation of US17/468,509.

Related Child Applications (Applications that claim priority to US11818591B2's family):
The patent document also lists several "Related Child Applications" that are continuations of this patent or its family members. These are all continuations claiming the same priority date of 2013-10-30:

Related Family Members

The "Family" section on the Google Patents page lists several applications under "Family ID=52995357". These include:

  • US14/526,799 (US10034179B2), filed 2014-10-29.
  • US16/039,660 (US11115834B2), filed 2018-07-19.
  • US17/468,509 (US11818591B2), filed 2021-09-07.
  • And all the "Related Child Applications" mentioned above.

Projected Expiration Date

The standard patent term for applications filed on or after June 8, 1995, is 20 years from the earliest claimed non-provisional filing date. In this case, the earliest priority date is October 30, 2013.

Therefore, the base expiration date (without any adjustments or extensions) would be October 30, 2033.

The Google Patents page explicitly lists an "Anticipated expiration" date of 2034-10-29. This anticipated expiration date already accounts for any Patent Term Adjustment (PTA) that has been calculated and applied to the patent. As noted above, PTE is not applicable.
