Judge Stark grants motion for summary judgment of invalidity for obviousness.

Judge Leonard P. Stark recently granted a motion for summary judgment of invalidity for obviousness filed by several generic defendants in an ANDA suit involving methods for treating or preventing osteoporosis through dosing of risedronate. Warner Chilcott Company, LLC v. Teva Pharmaceuticals USA, Inc., et al., C.A. No. 08-627-LPS (D. Del. Mar. 28, 2014). Judge Stark cited two related litigations in the District of New Jersey where similar patented methods and the same prior art were considered, and concluded that “Defendants have presented clear and convincing evidence that the prior art demonstrates that high doses of risedronate are safe and effective.” Id. at 11.
