Open the CIPO recordAbstract From the Canadian patent
An EMI/RFI shielding gasket comprising a resilient elastomeric core enveloped with a fine open format knit or, braided wire mesh and having a strip of pressure sensitive adhesive disposed lengthwise along a surface of the gasket. This strip of adhesive allows the gasket to be removably fastened to an enclosure, circumventing the need for a metal clip and thus making the gasket lighter and less expensive than conventional gaskets.

Why it's free to use
- Filed March 15, 1990 and granted September 27, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 15, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 15, 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.
