The aim of this invention is to provide universal toilet fish which will be able to remove all the objects which might fall into the toilet.

Why it's free to use
- Filed May 20, 1994 and granted May 12, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 20, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 20, 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.
