Most Frequent Ground of Rejection Is Prior Art
Note:
Claims must be rejected if they are not novel under 35 U.S.C. 102 or obvious under 35 U.S.C. 103.

By far the most frequent ground of rejection is on the ground of unpatentability in view of the prior art, that is, that the claimed subject matter is either not novel under 35 U.S.C. 102, or else it is obvious under 35 U.S.C. 103. The language to be used in rejecting claims should be unequivocal. See MPEP § 707.07(d).
