Open the CIPO recordAbstract From the Canadian patent
The inventors have isolated novel genes with a high homology to the T. lanuginosus lipase gene and are thus well suited for use in gene shuffling. Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The expressed proteins may further be screened to identify lipolytic enzymes with improved properties. The invention also provides a polynucleotide comprising …

Why it's free to use
- Filed February 25, 2002 and granted September 8, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 25, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
