Held: Genes are products of nature

Today the US Supreme Court rules that there cannot be patents on genomic DNA information (PDF – 139kb), only modified DNA products like cDNA. Note that the decision was effectively unanimous, the opinion was written by Thomas, and Scalia’s concurrent opinion is essentially an admission of ignorance in the specialty field. I have not had time to read the full opinion, but at initial review this seems like a very reasonable result. Naturally occurring DNA sequences are, well, natural. Sequences modified with intent may be patent eligible. It will be interesting to see in the future if discovery of naturally occurring sequences that are identical to patented sequences modified naively to match a natural variant will invalidate patents.

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…Myriad did not create or alter either the genetic information encoded in the BCRA1 and BCRA2 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…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. – SCOTUS (PDF -139kb)
