Open the CIPO recordAbstract From the Canadian patent
The present invention provides a panel of transcriptional activator fusion proteins which comprises both tetracycline controlled transactivator proteins and reverse tetracycline transactivator proteins. These transactivators have novel phenotypes such as alterred basal transcriptional activity in the absence of doxycycline, altered induced transcriptional activity in the presence of doxycycline, or differential induction by tetracycline and analogs of tetracycline.

Why it's free to use
- Filed June 5, 2000 and granted February 25, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 5, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 5, 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.
