patents/licenses and Taq/Pfu DNA polymerase

[news.uni-muenster.de]

Hello!

A lot of compansie in Germany sell Taq DNA polymerase and Pfu DNA polymerase 
without any license.

What about licenses and patents of these products in Germany and Europe, 
respectively?

Who ones the patent for Pfu DNA polymerase and how long will it be valid?

Can a compoany in Germany sell Taq ond/or Pfu without any license, is it 
legal?

And whout about products like HotStart Taq DNA polymerase (Taq DNA 
polymerase plus antibodies against the Taq)?

Thank you

Jo
