PCR machine patents

[the End]

A machine which alternates the temperature of an incubation chamber
between different value is not necessarily a "PCR Machine". It has been 
pointed out that the concept of amplification of a DNA sequence by annealing
oligonucleotides was proposed well before the current patents were 
filed, and that this evidence was improperly introduced and therefore
excluded at the last go-round between Dupont and Cetus. Lets hope the 
mamufactures of "Thermocylers" are more adept this time.
