It's a continuation application for an older patent as mentioned in the description. That's why new applications and grants keep appearing with the same name as older ones.

Apparently they're used to expand the scope of existing patents in order to increase the strength of a patent portfolio.

In this case the original application was filed in 2008, which means it'll expire in 2033 if they can get a 5 year extension on top of the regular 20 years.
