I'm attempting to form a non-provisional utility patent relating to a method and apparatus used for chemical separations. My question is concerning field of invention and subsequently prior art. Here’s an example of my issue:
I’ve come up with a novel way for coffee shops to extract caffeine from coffee beans (I.e. make a cup of coffee). My new method and apparatus are substantially different from any of the coffee machines used in the industry today. However, the invention has similarities when compared to industrial caffeine extractors. These industrial extractors are not extracting caffeine with the intent of making cups of coffee, but rather mass producing products such as energy pills.
Now, I'm not concerned with my invention being too similar when compared with the industrial extractor. I’m only wondering if the industrial processes should be included within the Background of the Invention. Should I mention these as prior art? Or should I focus on the methods and apparatus used by the coffee shops representing the target application of my invention?
Hope this question isn’t too convoluted to understand. Any help would be greatly appreciated.
