I recently contacted Hoffman la Roche, the holders of the PCR patent,
with a view to obtaining a license at some future date, for assays
being developed in my laboratory.
Much to my surprise, I received a reply not from Roche but from
Perkin-Elmer, informing me that they have obtained the rights to
licence agricultural applications of PCR from Roche.
What shocked me however, were the conditions that pekin elmer are
1) A 10,000 USD one-off payment
2) A 15% royalty based on the *cost* of the assay.
