• Filing Date: April 7, 2006
• Issue Date: October 30, 2007
• Statutory Term: 20 years from the earliest non-provisional filing date.
• Calculated Expiration Date: April 7, 2026

A review of the patent's prosecution history indicates zero days of Patent Term Adjustment (PTA) were granted by the USPTO. The application was processed and issued well within the timeframes that would typically trigger adjustments for USPTO-caused delays.

Therefore, the projected expiration date of the patent was April 7, 2026. As the date of this analysis is April 26, 2026, U.S. Patent No. 7,288,822 has expired and is now in the public domain.

Application History and Related Patents

The '822 patent is part of a small patent family that originated from a single U.S. application.

• Parent Application:

  • Filed: April 7, 2006
  • Status: Issued as U.S. Patent No. 7,288,822 on October 30, 2007.

  • Status: Issued as U.S. Patent No. 7,524,716 on April 28, 2009.

This family relationship is explicitly documented in the "Related U.S. Application Data" section of the '716 patent, which states it is a divisional of application Ser. No. 11/399,827, now U.S. Pat. No. 7,288,822.

Summary of Patent Family:

Patent/Application No.	Filing Date	Issue Date	U.S. Patent No.	Relationship	Status	Expiration Date
11/399,827	Apr 07, 2006	Oct 30, 2007	7,288,822	Parent Application	Expired	Apr 07, 2026
11/755,669	May 30, 2007	Apr 28, 2009	7,524,716	Divisional of '822	Expired	Apr 07, 2026

Because the divisional '716 patent stems from the parent '822 patent's application, it shares the same priority date of April 7, 2006. Its 20-year term is also calculated from this date, meaning it expired on the same day as the '822 patent.
