Unlike the laws of other nations that include broad exclusions to eligible subject 
matter, such as European restrictions on software and other method patents, see 
European Patent Convention of 1973, Art. 52(2)(c) and (3), and prohibitions against 
patents deemed contrary to the public morality, see id. at Art. 53(a), U.S. law and policy 
have embraced advances without regard to their subject matter.  That promise of 
protection, in turn, fuels the research that, at least for now, makes this nation the world’s 
innovation leader.

With all of its legal sophistry, the court’s new test for eligibility today does not 
answer the most fundamental question of all:  why would the expansive language of 
section 101 preclude protection of innovation simply because it is not transformational 
or properly linked to a machine (whatever that means)?  Stated even more simply, why 
should some categories of invention deserve no protection? 
This court, which reads the fine print of Supreme Court decisions from the 
Industrial Age with admirable precision, misses the real import of those decisions.  The 
Supreme Court has answered the fundamental question above many times.  The 
Supreme Court has counseled that the only limits on eligibility are inventions that 
embrace natural laws, natural phenomena, and abstract ideas.  See, e.g., Diehr, 450 
U.S. at 185 (“This Court has undoubtedly recognized limits to § 101 and every discovery 
is not embraced within the statutory terms.  Excluded from such patent protection are 
laws of nature, natural phenomena, and abstract ideas.”).  In Diehr, the Supreme 
Court’s last pronouncement on eligibility for “processes,” the Court said directly that its 
only exclusions from the statutory language are these three common law exclusions:
