What is going on in the world? I always believed that "common knowledge" is
not patentable. Anything that were published prior to patent (application
file date) are not patentable. That is why some of the industry guide their
dearest IP as "Trade Secret", the boardest possible claim as "patent", and
fight to publish papers if it is potentially might hurt the chance to get
some patent out (avoid it to become "common knowledge")...Is that all
changed lately?
