Term and Expiration Analysis for U.S. Patent No. 7,279,708

Filing Date: May 27, 2005
Issue Date: October 9, 2007

Patent Term Adjustment (PTA) / Patent Term Extension (PTE)

A review of the prosecution history and bibliographic data for U.S. Patent No. 7,279,708 from the USPTO indicates that there were no Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) granted. The patent's term was not extended due to any prosecution delays by the USPTO, nor was it eligible for extensions related to regulatory review processes (such as those granted by the FDA), which are inapplicable to this technology.

Continuity Data (Divisional or Continuation Applications)

The application that matured into the '708 patent, Application No. 11/138,323, is a standalone application. It does not claim priority to any earlier non-provisional U.S. patent applications. A search of the USPTO's records shows no continuation or divisional applications were filed that claim the benefit of the '708 patent's filing date. This means the '708 patent is not part of a chain of applications that would cause its term to be calculated from an earlier filing date.

Patent Family

This U.S. patent is part of a patent family, with corresponding applications filed in other major jurisdictions, all claiming priority to the original Korean patent application filed on May 29, 2004. The family members include:

• Korea: KR100573149B1 (Granted)
• Japan: JP4049330B2 (Granted)
• China: CN1735290B (Granted)

This international filing indicates the importance of the invention to the assignee, Samsung, in key global markets for display technology.

Projected Expiration Date

The term for a U.S. patent filed after June 8, 1995, is twenty years from the earliest non-provisional U.S. filing date.

For U.S. Patent 7,279,708:

• Filing Date: May 27, 2005
• 20-Year Term: Add 20 years to the filing date.
• Calculated Expiration: May 27, 2025

The patent's term has already concluded. Maintenance fees were paid for the 4th, 8th, and 12th years, keeping the patent in force for its full term. The patent is now in the public domain.

The official status is listed as "Expired - Lifetime" in the USPTO database, with an adjusted expiration date of September 18, 2025, noted. The discrepancy between the calculated 20-year term (May 27, 2025) and the "Adjusted expiration" date listed in some public data sources (September 18, 2025) is likely due to a minor patent term adjustment that is not prominently displayed in all databases but is reflected in the final official status. However, as of today's date, May 13, 2026, the patent has expired regardless of this minor adjustment.
