Extensions

To provide details on Patent Term Adjustments (PTA), Patent Term Extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US Patent 8471812, a direct search of the USPTO database for this specific patent number is necessary. However, as a large language model, I do not have direct, real-time access to the USPTO's Patent Center or Public Search tools. The USPTO itself states that it does not calculate expiration dates and provides a downloadable calculator for estimation purposes.

Based on the general information provided in the patent text:

• Projected Expiration Date: The patent is listed as "Active" with an "adjusted expiration" date of 2031-04-23.
• Continuation/Divisional Applications: The patent abstract and description do not explicitly state if US8471812 is a continuation or divisional application. However, the legal status information mentions a priority date of 2005-09-23 to US11/233,043 and also mentions a priority to US13/901,949 on 2013-05-24. These indicate a relationship to other applications. For applications filed after June 8, 1995, the patent term is generally 20 years from the earliest filing date in a chain of applications (continuation, divisional, or continuation-in-part).
• Related Family Members: The patent lists US20090267895A1 and US20140139435A1 as "Other versions" or related publications. Additionally, it lists EP06815091.1A and PCT/US2006/036795 as priority applications.

To definitively determine any specific Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) that may have been granted to US8471812, or to precisely identify all continuation/divisional applications and their impact on the patent term, one would need to access the "Patent Term Adjustment" section within the USPTO's Patent Center for this specific patent number. PTA is granted to compensate for delays caused by the USPTO during prosecution. PTE can be awarded for delays in obtaining regulatory approval for certain patented products.
