February 28, 2008 - Procter & Gamble Co. won a patent infringement lawsuit against Teva Pharmaceuticals USA Inc. over a generic version of P&G's osteoporosis drug Actonel that the Israel-based Teva wanted to market in the US.
P&G filed the lawsuit against Teva to enforce P&G's patent for risedronate, the active ingredient in Actonel. Teva had claimed P&G's Actonel patent was not valid due to the obviousness of the invention.
I think P & G should have won as they did. Oblviousness of an invention is no excuse. The same goes with your driver's license and many other important issues. A person and/or company needs to be informed of important issues such as patents and patent infringement.
