Extensions

US Patent 8,018,880 was filed on March 25, 2008, and issued on September 13, 2011.

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

The patent explicitly states that it is "Active, expires 2028-08-13" and includes an entry for "Adjusted expiration" on that date. [cite: Current time information in United States of America.]

Patent Term Adjustment (PTA) is granted by the USPTO to compensate for administrative delays during patent prosecution. It adds to the typical 20-year term from the earliest claimed filing date. The specific "Adjusted expiration" date of August 13, 2028, indicates that some PTA was applied to US 8,018,880.

Patent Term Extensions (PTE) are distinct from PTA and are typically granted for delays due to premarket regulatory review, such as for pharmaceuticals. There is no information in the provided text to suggest that US 8,018,880 received a Patent Term Extension under 35 U.S.C. 156.

Continuation and Divisional Applications

The patent is listed as claiming priority to U.S. Provisional Patent Application No. 60/920,227, filed March 26, 2007, and US12/079,413, filed March 25, 2008. [cite: Current time information in United States of America.]

The USPTO Open Data Portal provides a "Continuity" section where information regarding parent and child applications can be found. A specific search of the USPTO database would be required to definitively confirm if US 8,018,880 is a continuation or divisional of other applications, or if it has led to any such applications. However, based on the provided text, the application number US12/079,413 is listed as an "Application filed by Brixham Solutions Ltd" on March 25, 2008, and US8018880B2 is the publication of this application. [cite: Current time information in United States of America.] It claims priority to the provisional application.
