The non-continuous retroreflective pattern may include retroreflective regions and non-retroreflective regions arranged such that thermal decay through the protective garment is not substantially decreased in the regions corresponding to the retroreflective material.

Why it's free to use
- Filed June 27, 2002 and granted May 14, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2022.
