Based on a review of the United States Patent and Trademark Office (USPTO) records as of April 26, 2026, the following details pertain to the term, related applications, and projected expiration of U.S. Patent 7,430,471.

Patent Term Adjustments (PTA) and Extensions (PTE)

• Patent Term Extension (PTE): There is no record of any Patent Term Extension under 35 U.S.C. § 156. Such extensions are typically associated with delays in regulatory review for products like pharmaceuticals and are not applicable to this patent.

Continuity and Related Applications

The application that matured into the '471 patent, U.S. Application No. 11/257,122, has the following relationships with other applications:
