Open the CIPO recordAbstract From the Canadian patent
The production of an active Pseudomonas glumae lipase isolated from P. glumae PGl (CBS 322.89) and other lipases suitable for application in detergent systems is described in homologous, but particularly in heterologous hosts e.g. Bacillus subtilis. For the latter a "helper function" or "lipase-specific stabilization/translocation protein" is needed, for which a gene is provided which when expressed in, concert with the lipase gene can improve the stabilization, of the intermediates involved in the production and translocation/secretion of the lipase. The hosts are transformed by recombinant DNA methods and modified lipases can be made by site-directed mutation or classical mutation …

Why it's free to use
- Filed July 4, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 4, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 4, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
