Open the CIPO recordAbstract From the Canadian patent
A flexible electric heater may be formed from multiple congruent planar layers secured to one another to form a laminate in a variety of configurations. A junction box is adhered to the planar layers over an opening in an outer layer. An adhesive catchment area in the laminate is filled with adhesive, and the adhesive extends into the junction box where it fills a second adhesive catchment area. The mass of continuous adhesive thus formed seals and bonds the junction box to the flexible planar layers. Conductors from the electrical heater pass through the adhesive and may be strain relieved.

Why it's free to use
- Filed November 19, 1996 and granted August 13, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 19, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 19, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
