Roche now owns the Cetus PCR patent portfolio. The Mullis patent on the
PCR process itself, US4683202 "Process for amplifying nucleic acid
states on the cover page:
Notice: The portion of the term of this patent subsequent to Jul. 28, 2004
has been disclaimed.
I'm no lawyer, but my interpretation is that it expires in less than two
years. Your MJ Research thermal cycler should last much longer. It would
seem that this situation should affect the licensing fee.
For the record, I have no connection to either company.
