Genes and Patents

The US Supreme Court has just ruled in the Myriad case. The Court holds:

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

(a) The Patent Act permits patents to be issued to “[w]hoever invents or discovers any new and useful . . . composition of matter,” §101, but “laws of nature, natural phenomena, and abstract ideas”“ ‘are basic tools of scientific and technological work’ ” that lie beyond the domain of patent protection,The rule against patents on naturally occurring things has limits, however. Patent protection strikes a delicate balance between creating “incentives that lead to creation, invention, and discovery” and “impeding]the flow of information that might permit, indeed spur, invention.”  This standard is used to determine whether Myriad’s patents claim a “new and useful . . . composition of matter,” §101, or claim naturally occurring phenomena. 

(b) 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. cDNA is not a “product of nature,” so it is patent eligible under§101. 

(c) 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. 

(d) This case, it is important to note, does not involve method claims, patents on new applications of knowledge about the BRCA1 and BRCA2 genes, or the patentability of DNA in which the order of the naturally occurring nucleotides has been altered.

This is a game changing decision and is worth the reading.
