The document says, specifically, on page 2:
…
6,368,227 B1* 4/2002 Olson…472/118
…
* cited by examiner
A handful of other the "cited by examiner" references are to apparently useful references (other patents that cover antipiracy stuff). Dunno why the examiner would add the swing patent unless perhaps they thought their system was a joke? Or am I misreading what the asterisk means? (The examiner also cited the "method of exercising a cat" patent in this document.)
If you look very closely at this Microsoft patent document (http://www.google.co.uk/patents/US8181265?printsec=abstract#...), on page 2, you'll see that the reference to the swing patent has an asterisk next to it.
