Open the CIPO recordAbstract From the Canadian patent
A halogenated organic compound is introduced into a plasma. In the plasma state, substances are very reactive and chemical substances which are not readily decomposed such as halogenated organic compounds are decomposed in a short time. Specifically in a, high-temperature plasma exceeding 10,000°C almost all, molecules are considered to dissociate into atoms. A reactive substance such as water is introduced into a plasma together with a halogenated organic compound. The decomposed halogenated organic compound is caused to react with the reactive substance, for preventing the decomposed organic compound from returning to its original state.

Why it's free to use
- Filed November 9, 1989 and granted May 12, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 9, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
