Intellectual Property – patents — DNA

A naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated, but cDNA is patent eligible because it is not naturally occurring.

Myriad’s DNA claim falls within the law of nature exception. Myriad’s principal contribution was uncovering the precise location and genetic sequence of the BRCA1 and BRCA2 genes. Diamond v. Chakrabarty, 447 U. S. 303, is central to the patent-eligibility inquiry whether such action was new “with markedly different characteristics from any found in nature,” id., at 310. Myriad did not create or alter either the genetic information encoded in the BCRA1 andBCRA2 genes or the genetic structure of the DNA. It found an important and useful gene, but groundbreaking, innovative, or even brilliant discovery does not by itself satisfy the §101 inquiry. See Funk Brothers Seed Co. v. Kalo Inoculant Co., 333 U. S. 127. Finding the location of the BRCA1 and BRCA2 genes does not render the genes patent eligible “new . . . composition[s] of matter,” §101. Myriad’s patent descriptions highlight the problem with its claims: They detail the extensive process of discovery, but extensive effort alone is insufficient to satisfy §101’s demands. Myriad’s claims are not saved by the fact that isolating DNA from the human genome severs the chemical bonds that bind gene molecules together. The claims are not expressed in terms of chemical composition, nor do they rely on the chemical changes resulting from the isolation of a particular DNA section. Instead, they focus on the genetic information encoded in the BRCA1 and BRCA2 genes. Finally, Myriad argues that the Patent and Trademark Office’s past practice of awarding gene patents is entitled to deference, citing J. E. M. Ag Supply, Inc. v. Pioneer Hi-Bred Int’l, Inc., 534 U. S. 124, a case where Congress had endorsed a PTO practice in subsequent legislation. There has been no such endorsement here, and the United States argued in the Federal Circuit and in this Court that isolated DNA was not patent eligible under §101.

cDNA is not a “product of nature,” so it is patent eligible under§101. cDNA does not present the same obstacles to patentability as naturally occurring, isolated DNA segments. Its creation results in an exons-only molecule, which is not naturally occurring. Its order of the exons may be dictated by nature, but the lab technician unquestionably creates something new when introns are removed from a DNA sequence to make cDNA.

689 F. 3d 1303, affirmed in part and reversed in part.

12-398 Association for Molecular Pathology v. Myriad Genetics, Inc.

Thomas, J.; Scalia, J., concurring.
