Open the CIPO recordAbstract From the Canadian patent
The shoulder area of wedding and party dresses are usually puffed up using crinoline netting which is very, cumbersome and difficult to work. A simple solution to this problem includes a fabric panel in the shape of a truncated segment of a circle with a pocket in the long straight edge thereof. When the convex side of the panel is pleated or otherwise gathered, the panel assumes an arch shape. Inserting of a resilient strip of plastic into the pocket and sewing of the gathered edge into a sleeve at the seam between the bodice and sleeve of a garment results in a puffy shoulder which retains its shape.

Why it's free to use
- Filed September 9, 1994 and granted January 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 9, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
