Robert K S noted
... the supreme importance of the language "A person shall be entitled to a patent unless..."
And patentsusa reminded us that
Judge Dyk’s concurrence provided a discussion of how the test was understood at the time of the Patent Act of 1793, on which the current statutory language is based. Judge Dyk noted that “methods of organizing human activities” were never considered patentable at the time the patent statutes were written, even though they clearly existed at that time.
I'm not a judge or even an attorney, but my opinion is that the black letter law
shall be entitled to a patent unless ... should trump tradition.
In other areas of the law, such as taxes, clever attorneys are always figuring out ways to skirt the letter of the law by "inventing" new investment schemes. And Congress, using its wisdom and considering the impact on their campaign contributions, may choose to outlaw such investment schemes. But unless and until the law becomes effective, the activity is not illegal.
By analogy, patent law plainly states that a person
shall be entitled to a patent unless and then provides a list of "unlesses". Congress can take the reasoning of Judge Dyk's opinion and incorporate that into law. But until "a method of organizing human activities" is listed as one of the "unlesses", or proscribed as not being an invention or a discovery, such methods should be patentable.
I'm not going to submit this note to the Supremes as an amicus curić; I'm guessing that Justice Roberts and his band of eight will have the benefit of more scholarly analyses.
