The US6967208 was filed in 17 Sep 2002, published in 22 Nov 2005. With 20 years from date of filing as an expiry date for a patent it would expire on 16 Sep 2022. However needed to know if there was an extension provided to this patent.
You can check this by yourself on the US Public Pair site. Select "Patent Number" and enter 6967208. When the specific record is visible, click on the "Patent Term Adjustments" tab. When I do this I see "Total PTA Adjustments:" listed as 139 days.
