Open the CIPO recordAbstract From the Canadian patent
A cloning vector contains a DNA sequence derived from a Nocardioform microorganism, and is capable of expressing the DNA sequence in a host microorganism. Recombinant cholesterol oxidase is produced by a host microbial cell transformed with a cloning vector containing cholesterol oxidase encoding DNA derived from a Nocardioform microorganism. A method for determining cholesterol oxidase in a sample of fluid from a human includes contacting the sample with the Nocardioform microorganism derived recombinant cholesterol oxidase.

Why it's free to use
- Filed November 14, 1989 and granted December 14, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 14, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 14, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
