I may be ignorant of us law but cannot one devise a novel mutation that 
improves taq however marginally?

would this get around the patent laws?

(Patenting some thing you did not invent surely is a little difficult. 
Patenting a process I can understand but a naturally occurring product? Ok,
so recombinant taq is not natural because of the production, so just use a
differrent method of production (different vector). It's a bit like patenting
grass for feeding cattle....)
