In  J.E.M. Ag Supply, Inc. v. Pioneer Hi-Bred International, Inc., 534 U.S. 124 
(2001), the Court described Section 101 as a “dynamic provision designed to 
encompass new and unforeseen inventions,” id. at 135, that case arising in the context 
of eligibility of newly developed plant varieties for patenting.  The Court stated: “As in 
Chakrabarty, we decline to narrow the reach of §101 where Congress has given us no 
indication that it intends this result.”  Id. at 145-46.  The Court reiterated that “Congress 
plainly contemplated that the patent laws would be given wide scope,” id. at 130 
(quoting Chakrabarty, 447 U.S. at 308), and that the language of Section 101 is 
“extremely broad,” id.  This is not language of restriction, and it reflects the statutory 
policy and purpose of inclusion, not exclusion, in Section 101. 
The Court’s decisions of an earlier age do not support this court’s restrictions of 
Section 101
 
 
My colleagues also find support for their restrictions on patent-eligible “process” 
inventions in the pre-Section 101 decisions O’Reilly v. Morse, 56 U.S. (15 How.) 62 
(1853), Cochrane v. Deener, 94 U.S. 780 (1876), and Tilghman v. Proctor, 102 U.S. 707 
(1880).  Although the Court in Benson and in Flook took care to state that these early 
decisions do not require the restrictions that the Court was rejecting, this court now 
places heavy reliance on these early decisions, which this court describes as 
“consistent with the machine-or-transformation test later articulated in Benson and 
reaffirmed in Diehr.”  Maj. op. at 12.  As I have discussed, no such test was “articulated 
in Benson” and “reaffirmed in Diehr.” 
However, these early cases do show, contrary to the majority opinion, that a 
“process” has always been a distinct category of patentable invention, and not tied to 
either apparatus or transformation, as this court now holds.  For example, in Tilghman v.
