Patent Litigation and PTAB cases:	See patent lawsuits and PTAB cases for patent 9,085,601
Patent Claims:	1. A pharmaceutical composition prepared from a crystalline monohydrate form of the compound (1-{9-[(4S,2R,3R,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-6-aminop- urin-2-yl}pyrazol-4-yl)-N-methylcarboxamide by adding at least one pharmaceutically acceptable carrier. 2. The pharmaceutical composition of claim 1, wherein the monohydrate is substantially free of 2-hydrazinoadenosine. 3. The pharmaceutical composition of claim 2, wherein the monohydrate is substantially free of other hydrates or amorphous form. 4. The pharmaceutical composition of claim 3, wherein the monohydrate has a purity of at least about 99.6%. 5. The pharmaceutical composition of claim 4, wherein the monohydrate exhibits an X-ray powder diffraction pattern having peaks at diffraction angle 2.theta. (.degree.) of about 6, about 9, about 11, about 13, about 14.5, about 16.5, and about 18 as measured by Cu-K.alpha.1 X-ray powder diffractometry.
