Thanks for the kudos on abstruse, I still remember the obtuse quote in the Shawshank Redemption.
As for: "I would REALLY like to know what he meant", I did the best I could/can in my prior reply.
I have no legal training, but my understanding is that "Lifescan's Accused Products" means that Lifescan sells products that infringe on DECN's patent.
P.S. I enjoyed your YouTube link, and agree it was appropriate.
