Appeal No. 2003-1092 Application No. 09/692,730 select specific concentrations from patentee’s broadly disclosed range which fall within the Appellants’ disclosed and claimed range of lysine concentration. If so and if the Examiner further believes that the slurry resulting from these selections is indistinguishable from the slurry claimed by the Appellants, the Examiner must express these beliefs and the reasons therefor in the context of a rejection under 35 U.S.C. § 103. On the other hand, if the Examiner believes the appealed claims are patentable over Grumbine, this belief and the reasons therefor must be expressly stated in the record of this application file. In any case, it is paramount that the record be clarified as to whether and why the Examiner considers the appealed claims to be patentable or unpatentable over the above discussed disclosure of Grumbine. 66Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
