>What about licenses and patents of these products in Germany and Europe,
Taq Patent was ruled to be valid in Europe i.e. Roche won. There is no
further appeal court within Europe. Roche patent stands.
>Who ones the patent for Pfu DNA polymerase and how long will it be valid?
Stratagene patent and primarily an NEB patent that covers all polB type
sequences that hybridise to VENT DNA sequence under conditions specified
in the patent. Basically any polB sequence from a Pyrococcus or
Thermococcus is covered due to very high percentage DNA homology.
European patent office has a very good search engine and will pull up
all the granted patents and there dates.
>Can a compoany in Germany sell Taq ond/or Pfu without any license, is it
You would infringe the patents, but it is up to the patent owners to
pursue you should they wish to. If they pursue then you may need deep

All monoclonals to Taq covered by patent issued to Kodak and now owned
by I can't remember who. All Hotstart methods are covered by patents,
regardless of what they are.
> And how with mixtures from Taq
Taq:Proof reading enzyme mixes covered under a Wayne Barnes patent now
owned by Takara Bio.
I love deadlines. I especially like the whooshing noise they make as
