I agree that was a pretty good summary of the SCOTUS ruling, but I had to laugh when I read the following statement from Justice Thomas:
“but the lab technician unquestionably creates something new when cDNA is made.”
Except of course for those doggone single exon coding region gene segments that occur in some genes, or bioacitve peptides encoded within single genomic exons, of which there are many.
The concept of cDNA patentability versus the gene sequence non-patentability is silly on one level to those that have cloned both genomic and complementary DNAs. The ideas and methods are similar, as well as many anticipated uses, but essentially only a reverse transcription step makes all the difference.
