Date of Analysis: May 13, 2026

This report details the patent term adjustments, related applications, and the projected expiration date for US Patent 8,234,705.

Patent Term Adjustments (PTA) and Extensions (PTE):

A Patent Term Adjustment (PTA) can be granted to compensate for delays caused by the U.S. Patent and Trademark Office (USPTO) during the patent examination process. For US Patent 8,234,705, there is a significant patent term adjustment. The application for this patent (US 11/237,003) was filed on September 27, 2005, and the patent was granted on July 31, 2012. The lengthy prosecution period resulted in a notable adjustment. While the precise calculation of the PTA is not detailed in the available public records, the "Adjusted expiration" date is listed as November 25, 2029.

There is no indication of any Patent Term Extension (PTE) under 35 U.S.C. § 156, which is typically granted for delays in regulatory review by agencies such as the Food and Drug Administration (FDA) and is not applicable to this technology area.

Continuity and Divisional Applications:

US Patent 8,234,705, which issued from application number 11/237,003, claims priority to U.S. Provisional Patent Application No. 60/613,909, filed on September 27, 2004. There is no record of any continuation or divisional applications filed that claim priority to application number 11/237,003. Therefore, this patent does not appear to be part of a larger family of pending applications or issued patents stemming from continuation or divisional filings in the United States.

Patent Family Members:

Based on the available information, US Patent 8,234,705 does not have any direct foreign counterparts or other patent family members. The priority claim is limited to the earlier U.S. provisional application.

Projected Expiration Date:

A U.S. patent filed after June 8, 1995, generally has a term of 20 years from the earliest non-provisional filing date. The application for US Patent 8,234,705 was filed on September 27, 2005. Without any adjustments, the patent would expire on September 27, 2025.

However, due to the aforementioned patent term adjustment, the official "Adjusted expiration" date for US Patent 8,234,705 is November 25, 2029. This indicates a substantial adjustment period was granted due to delays during the patent's prosecution.
