Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Rossignol (US 2008/0251542 A1) as applied to claim 1 above. Re: Claim 8, Rossignol discloses the claimed invention including the inner wall of the lower bush of the said inner plug is provided with four equally spaced wall guide grooves, correspond to the thru-holes on top of the inner plug (Fig. 1, inner plug central column defines 4 equally spaced grooves to deliver fluid to the thru holes) except for specifying the claimed number of three equally spaced grooves corresponding to three thru holes. However, it would have been obvious to one having ordinary skill in the art at the time of the effective filing date to include three grooves and three through holes, since such a modification since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The references cited on the PTO-892 provides additional examples of small spray pump heads.
