Allowable Subject Matter Claim 5 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 5, Caswell discloses, the splatter-reducing device of claim 1, however, Caswell does not explicitly disclose, wherein the shroud is slidably coupled to the support frame and the shroud comprises: a top member comprising a top sub-member and a bottom sub-member adjoined at two opposing edges to form a support frame pocket that sandwiches the support frame when the shroud is slidably coupled to the support frame; and four flaps affixed to four respective edges of the top member such that the four flaps suspend from the bottom sub-member to enclose the central region for placing food or liquid to be heated within the cooking appliance. No additional evidence was found to reasonably render a case of obviousness against the claimed invention. As such, claim 5 is allowed. Claims 6-8 are also objected to as being dependent upon claim 5.
