Patent Term Adjustments (PTA)

US Patent 8259688 has an adjusted expiration date of 2030-05-22 due to Patent Term Adjustment (PTA). This is indicated on the Google Patents page for the patent, which states the legal status as "Active, expires 2030-05-22". [cite: https://patents.google.com/patent/[US8259688](/patent/US8259688)/en]

PTA is granted to compensate patent applicants for delays caused by the United States Patent and Trademark Office (USPTO) during the prosecution of a utility or plant patent application. These delays can include the USPTO failing to:

  • Issue a first office action or notice of allowance within 14 months of filing.
  • Respond to an applicant's reply within four months.
  • Issue the patent within four months of payment of the issue fee.
  • Issue a patent within three years of the actual filing date.

The overall PTA is calculated by summing various delays, with reductions for any delays caused by the applicant.

Patent Term Extensions (PTE)

There is no indication that US Patent 8259688 has received a Patent Term Extension (PTE). PTEs are typically granted for patents on certain human drug products, medical devices, animal drug products, and food or color additive products to restore patent term lost while awaiting premarket regulatory approval from a government agency. Since US8259688 is related to wireless communication systems, it would generally not be eligible for a PTE.

Continuation, Divisional, and Related Family Members

US Patent 8259688 claims priority to application number US11/469,794, filed on September 1, 2006. [cite: https://patents.google.com/patent/US8259688/en] The patent also lists other priority applications, including:

These indicate that US8259688 is part of a larger patent family, with multiple continuation applications (e.g., US13/180,135, US13/565,405, etc.) claiming priority back to the initial filing date of US11/469,794. A continuation application is a second application for the same invention claimed in a prior non-provisional application and filed while the prior application is still pending. Divisional applications arise from restriction requirements when the USPTO determines that an application claims more than one invention. The provided information does not explicitly state whether any of the listed applications are divisional applications, but they are clearly related family members.

Projected Expiration Date

The adjusted expiration date for US Patent 8259688 is 2030-05-22.

The statutory patent term is generally 20 years from the earliest non-provisional filing date. The initial filing date for US8259688's priority application was September 1, 2006. Therefore, without any adjustments, the patent would have expired on September 1, 2026. The PTA has extended its life by approximately 3 years and 8 months.
