Open the CIPO recordAbstract From the Canadian patent
A folded (e.g. Z-folded) mailer type business form is constructed so that it may be printed using an IBM 3800 printer without sticking to the printer fuser or backer rolls. Pressure sensitive adhesive patterns (e.g. discontinuous strips) are placed on the first face of a paper sheet near a first transverse edge, and the second face of the paper sheet near a second transverse edge. The spacings from the edge are about 5/16 inches in each case, sufficient to insure that the adhesive is not engaged by the printer rolls during pausing of the printer.

Why it's free to use
- Filed March 31, 1992 and granted August 7, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 31, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 31, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
