Does anyone know when the Roche patents on recombinant Taq polymerase expire for Europe and the US?
From what I know it expired at the end of 2005 and Europe at 2006.Here are two links that may help you.1) http://www.drugresearcher.com/news/ng.asp?id=59065-roche-s-patent2) http://www.applera.com/corpcomm/applerapress.nsf/ABIDisplayPress/E22007EB8AD1C1E188257032000516DA?OpenDocument&type=abi
Here is another link which corroborates that the US patent expired on March 28 2005...Advice on How to Survive the Taq Wars
However, the previously cited article may be off by one day, because the patent disclaimers of products using Taq reported here, here, and here indicate "The PCR process is the subject of European Patent Nos. 201,184 and 200,262 owned by Hoffman-LaRoche. Those patents will expire on March 28, 2006. The corresponding PCR process patents in the United States expired on March 29, 2005."
