To promote the Progress of … useful Arts, by securing for limited Times to … Inventors the exclusive Right to their respective … Discoveries.” This statement in our Constitution makes science the basis of our patent law.

Of course, this is easier said than done in light of the pace at which technology is advancing.

Central to this article is the court’s understanding of exactly what constituted “isolated DNA,” since patents now claiming isolated DNA may no longer be patent eligible or claims reciting “isolated DNA” or similar terms may be invalid.
