I would like to use the method disclosed (via claims) in this patent for my invention http://www.google.com/patents/US8568309 .
That is, I am creating a glucometer, using this inventor's method for rendering blood glucose values, but this is just one purpose of my glucometer. My innovation is not the method this patent divulges. My innovation is that I am adding functionality to this preexisting glucometer (for the sake of argument, lets say that I am inventing a glucometer that can ALSO turn water into wine).
Would this be considered infringement? If so, how does anything get created in the world if inventors can't create technology that is derivative (but not the same) as previous technology?
if this is not infringement, should I even include a description of his method in my patent? Should I claim his method and use his software block diagrams in my figures?
