Abstract From the Canadian patent
IFT GmbH 899/001 EP, Abstract, The firing target 1 is intended in particular for military firing practices and is distinguished by the fact that it is made from a polyethylene mixture. The mixture is preferably made up of HDPE and LDPE there, being 80% HDPE and 20% LDPE. In comparison with conventional firing targets of multi-layered plywood, this target 1 permits much higher numbers of shots. This is attributable to the fact that the penetration channel 10 has a distinctly reduced exit opening in relation to the entry opening (which corresponds to the projectile calibre K), the said exit opening in some cases even being completely closed again. (Fig. 2)

Why it's free to use
- Filed November 6, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 6, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
