Open the CIPO recordAbstract From the Canadian patent
Elements for making butt splices, in optical fibers, formed of a permanently deformable material e.g. metal or polymeric material, can be formed to define three surfaces 78, 79, and 86 for contacting the fibers to be spliced. The surfaces are formed between two legs 74 and 75 of an element such that when the legs are closed onto the fibers, the surfaces center the fibers by embedding the fibers into the surfaces and afford a resilient spring compression reserve force on the aligned fibers to maintain them in contact and clamp the fibers in the element.

Why it's free to use
- Filed October 12, 1990 and granted December 3, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 12, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 12, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
