Open the CIPO recordAbstract From the Canadian patent
The invention relates to recombinant insect poison allergens and to a specific method for producing them. Said , allergens can be varied according to whether they are produced using folds (conformations) that are identical or different to those that occur naturally. The proteins with folds that do not occur naturally have a reduced IgE reactivity or allergenity and can therefore be used as therapeutic agents in the immunotherapy of allergies.

Why it's free to use
- Filed November 27, 2000 and granted June 19, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 27, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 27, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
