Open the CIPO recordAbstract From the Canadian patent
Rhizomucor miehei derived aspartic proteases having enhanced milk clotting activity are obtained by deglycosylating the proteases or by producing them in microbial host species which do not glycosylate the proteases or which glycosylate them to lesser extend than Rhizomucor miehei strains naturally producing aspartic proteases in a glycosylated form. Such improved proteases are useful in cheese manufacturing.

Why it's free to use
- Filed December 20, 1995 and granted September 28, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 20, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
