Extensions

To get the most accurate and up-to-date information for US Patent 11329655, I will search the USPTO Patent Center and Patent Public Search databases. The USPTO does not calculate expiration dates for patents, but provides tools and guidance to help estimate them, taking into account factors like patent term adjustments (PTA), patent term extensions (PTE), and benefit claims to earlier applications.

Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) extends the term of a U.S. patent to compensate for certain delays caused by the USPTO during the prosecution of utility or plant patent applications. These delays include failing to issue a first office action within 14 months, respond to an applicant's reply within four months, or issue the patent within three years of the actual filing date. Any extension can be reduced by applicant-caused delays. The PTA calculation is typically displayed on the Patent Center screen and included in the Issue Notification Letter.

Patent Term Extensions (PTE):
Patent Term Extension (PTE) is available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost due to premarket government approval from a regulatory agency like the FDA. This patent (US11329655) relates to Field Programmable Gate Arrays (FPGAs) and high-frequency trading, which does not fall under these categories. Therefore, it is highly unlikely to be eligible for a Patent Term Extension under 35 U.S.C. § 156.

Continuation Applications, Divisional Applications, and Related Family Members:
Continuation, continuation-in-part, and divisional applications allow applicants to pursue additional patent protection descended from a "parent" application. These continuing applications must reference the parent's application number and filing date and must be co-pending (not yet abandoned or issued) when the continuing application is filed. The patent term for any continuing application is calculated from the earliest effective filing date under 35 U.S.C. § 154, which is 20 years from that date, subject to PTA. Related applications are usually listed in the "Related U.S. Application Data" section on the patent's front page or in the first paragraph of the specification.

Projected Expiration Date:
For U.S. utility patents filed on or after June 8, 1995, the patent generally expires 20 years from the earliest filing date of the patent application, with any applicable Patent Term Adjustments or Extensions.

To provide specific details on PTA, PTE, continuation/divisional applications, related family members, and the exact projected expiration date, direct access to the full patent prosecution history and official USPTO records for US11329655 through Patent Center (https://patentcenter.uspto.gov/) or Patent Public Search (https://ppubs.uspto.gov/pubwebapp/) would be necessary. These platforms provide the most accurate and current information. As an AI, I do not have live access to these dynamic databases to query and retrieve the real-time, detailed prosecution history for patent 11329655 to definitively determine PTA, identify any continuing applications, or precisely calculate the expiration date.

Based on the information available through Google Patents, the filing date for US11329655 is April 21, 2021. The stated anticipated expiration date is October 31, 2039. This would imply an adjustment to the standard 20-year term from the filing date, as 20 years from April 21, 2021 would be April 21, 2041. The difference (approximately 1 year and 6 months) could be due to various factors, including applicant delays or terminal disclaimers, as the initial Google Patents data indicates an anticipated expiration date, which may already factor in some adjustments. However, without direct access to the USPTO's official patent records for US11329655, I cannot confirm the exact PTA applied, the reasons for it, or details of any continuation or divisional applications.
