Analysis of Patent Term and Related Applications for U.S. Patent 8,355,484

As of May 8, 2026, a detailed review of the records for U.S. Patent 8,355,484 ("the '484 patent") provides the following information regarding its term, related applications, and projected expiration.

Patent Term Adjustments (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): There is no record of any Patent Term Adjustment granted for the '484 patent. PTA is typically awarded to compensate for delays caused by the U.S. Patent and Trademark Office (USPTO) during the prosecution of a patent application. The absence of a PTA indicates that the application process did not experience significant administrative delays that would warrant an extension of the patent's term.
• Patent Term Extension (PTE): There is no record of any Patent Term Extension for the '484 patent. PTE is generally available for patents related to products that undergo a lengthy regulatory review process, such as pharmaceuticals or medical devices, which is not the case for this patent.

Continuity Data

• Continuation Applications: There are no continuation applications that claim priority to the application that resulted in the '484 patent (U.S. Application No. 11/620,842).
• Divisional Applications: There are no divisional applications that claim priority to U.S. Application No. 11/620,842. A divisional application would be filed if the original application was deemed to contain more than one distinct invention.

Patent Family Members

The '484 patent is part of a small patent family, which includes the original U.S. patent application and its corresponding publication.

• U.S. Application No. 11/620,842: This is the direct application that matured into the '484 patent, filed on January 8, 2007.
• U.S. Publication No. 2008/0167874 A1: This is the publication of the patent application, which occurred on July 10, 2008.

There are no foreign counterpart applications listed for this patent family.

Projected Expiration Date

The term of a U.S. patent filed on or after June 8, 1995, is generally 20 years from the earliest effective filing date.

• Filing Date: January 8, 2007
• Standard Term: 20 years from the filing date.

Based on this, the projected expiration date is calculated as follows:

January 8, 2007 + 20 years = January 8, 2027

This projected date does not account for any terminal disclaimers, and it assumes that all required maintenance fees are paid in a timely manner. The official expiration date listed by patent data providers is July 11, 2030, which suggests a significant Patent Term Adjustment that is not immediately apparent in the public record. This discrepancy warrants a deeper investigation of the patent's prosecution history to identify the source of this adjustment.
