This is a bit dated, but touches on some of the patent issues recently discussed here (the full article may be found in the February 1999 issue of Nature Biotechnology): EST patent granted for human kinase homologs (Debra Robertson is the author) In November 1998, the US PTO awarded INCY the first patent for an EST claiming polynucleotides that identify and encode novel human kinases. The first of its kind, this patent could lead to new licensing revenue streams for Incyte and other companies with EST patent claims pending. ... some worry that the language of the patent enables the patentee to claim not only the EST but also the full gene of which it is part ... In response to the Incyte patent, Francis Collins, director of the US National Human Genome Research Institute, remarked at a meeting at the beginning of December that the broad issuing of this EST patent "is a disturbing turn of events" ... "it is disturbing that it seems to move in the direction of the broad claim, where the EST entitles you to claim the entire full–length cDNA and perhaps the whole gene." Specifically, the Incyte patent claims an expression vector comprising polynucleotides from a group of 44 ESTs. The legal and biotechnology communities are concerned that interpretation of the word "comprising" suggests broader patent rights not only to the EST sequence but also to adjacent sequences or even the full–length gene. ... Roy Whitfield, CEO of Incyte, says only that "This EST patent is no different from any of the other patents submitted by Incyte; its scope and validity will be determined by law." Jack Tribble, head of Merck's biotechnology patent group, points out another problem. "If there are multiple patents on ESTs within a well–known gene, one may need a license for all those ESTs so you can use the full–length gene" Whitfield, whose company offers nonexclusive licensing of ESTs, remarks that ESTs are research tools, "like PCR," the use of which is also protected by patent rights and requires a license.
