It would appear that some posters are getting confused between patents, trademarks and copyrights. They are distinctly different.
A patent confers on an inventor the sole right to use, make or sell an invention for a period of time (20 years in Canada).
A trademark is some distinctive mark, name or logo that permits consumers to distinguish the trademark holders products from other manufacturers.
Copyright deals with protecting literary, musicial, dramatic or artistic works for the lifetime of the creator + 50 years.
