This is not strictly true. Both the recombinant taq patent and the PCR
process patent are granted in Europe. I don't see that much is going to
change in the near future as virtually all enzyme sold is recombinant
and through licensed companies. From an article in New Scientist I
thought Roche had until October to respond. Only if it is abandoned then
will it they have lost the native patent.  

My mind's made up. Don't confuse me with the facts!
