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


Citing the candian 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 is most probably "dead".

  • I think it cannot be reinstate the dead patent, only if the application erroneously became dead – ASHU VERMA Apr 6 '17 at 8:53
