The polygons are , defined in objects instantiated from classes by control points and the layers as depth , values of control points. A pattern object sweeps rotationally about a wellbore in a , wellbore polygon to define a pattern of elements fewer in number with , distance from the wellbore.

Why it's free to use
- Filed December 15, 1999 and granted March 27, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 15, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 15, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
