How to determine Canadian patent life-time?



Is patent CA 2561773 A1 still valid or pending? Event shows: dead in 2008 Please inform of risk of patent infringement.

Citing the Canadian patent office website as reached through the Google Patents link on "dead" applications:

The date that an abandoned application could normally no longer be reinstated.

Dead Application 2009-09-21

Unless the owner is in a coma and can therefore reinstate the right after waking up (I don't know if this is possible in Canada), the patent application is most probably "dead".

I think it cannot be reinstate the dead patent, only if the application erroneously became dead – ASHU VERMA – 2017-04-06T08:53:19.200

1Just a little nit to pick, but I hate when applications are referred to as patents. – Eric S – 2019-05-29T19:18:06.503
