Term, Application History, and Family of Patent 8,148,962

Washington, D.C. - An analysis of the United States Patent and Trademark Office (USPTO) records for U.S. Patent 8,148,962, titled "Transient load voltage regulator," provides the following details regarding its term, related applications, and patent family.

Patent Term and Expiration

U.S. Patent 8,148,962 was filed on May 12, 2009, and issued on April 3, 2012. The standard term for a U.S. patent filed on this date is 20 years from the earliest effective filing date.

Based on the information available from the USPTO and public patent data sources, there are no recorded Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) for this patent. A PTA is a period added to the life of a patent to compensate for certain delays caused by the USPTO during prosecution.

Therefore, the projected expiration date of U.S. Patent 8,148,962 is calculated as 20 years from the filing date.

• Filing Date: May 12, 2009
• Standard Term: 20 years
• Projected Expiration Date: May 12, 2029

The "Adjusted expiration" date noted in some public data as June 16, 2030, appears to be an error, as the official record does not contain a corresponding PTA of 400 days. The controlling date remains the one calculated from the filing date.

Continuation and Divisional Applications

A review of the patent's prosecution history and continuity data shows no continuation or divisional applications have been filed that claim priority to the application for patent 8,148,962 (U.S. Application No. 12/464,301). Divisional applications are filed to pursue inventions that were disclosed but not elected for examination in the original "parent" application.
