Abstract From the Canadian patent

A free fruit-flavored chewing gum is provided with enhanced long-term flavor intensity without compromising the initial flavor burst and without necessarily relying on encapsulation as a means of flavor enhancement. The free fruit flavor is enhanced by including in the, chewing gum, a sufficient quantity of a restrainer having a Solubility Parameter within 2.0 J/m3 x 10-3 of the Solubility Parameter of the free fruit flavoring agent whose flavor is being enhanced. The free fruit flavoring agent is attracted to and/or attaches to, the water, insoluble restrainer to provide a controlled yet highly efficient, release of flavor during chewing.

Why it's free to use

  • Filed April 4, 1995 and granted August 10, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 4, 2015.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 4, 2017.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
