A dart (10) of a dart game provides a freely rotatable and reciprocating biased point (11) with a tip (12) that when the tip (12), hits a wire mesh (W) on a normal dart board or target (T) this , causes the point (11) to reciprocatingly collapse or migrate into the dart barrel (18) but due to the forward momentum of the flight of the dart (10) the forward momentum urges the tip (12) off of the wire (W) and causes penetration of the tip (12) into target (T) whereby eliminating, or reducing substantially incidents of, direct hit of the dart tip (12) on the wire (W) whereby the dart (10) would bounce off the dart board or target (T) onto the ground with no points being awarded for the shot. …

Why it's free to use
- Filed April 22, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 22, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 22, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
