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) 2, 4-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oya (U.S. Pub. 2015/0283813) in view of Fukuzawa et al (U.S. Pub. 2020/0001603) Regarding claim 2, Fukuzawa discloses wherein the flexible member (polyphenylene sulfide) has a lower strength than that of the orifice plate (harder material than the flexible plates) (Paragraph 0046) It would have been obvious to a person of ordinary skill in the art to incorporate before the effective filing date of the claimed invention to incorporate the teaching of Fukuzawa into the device of Oya, for the purpose of enhancing the quality of an object obtained by the liquid ejection (Paragraph 0089) Regarding claim 4, Fukuzawa discloses wherein the flexible member is composed of a member having a smaller Young’s modulus than that of the orifice plate (Paragraph 0026) It would have been obvious to a person of ordinary skill in the art to incorporate before the effective filing date of the claimed invention to incorporate the teaching of Fukuzawa into the device of Oya, for the purpose of enhancing the quality of an object obtained by the liquid ejection (Paragraph 0089) Regarding claim 5, Oya discloses the claimed invention except for wherein a difference in linear expansion coefficient between the flexible member and the orifice plate is within 15x10-6. It would have been obvious to one having ordinary skill in the art at the time the invention was made to incorporate wherein a difference in linear expansion coefficient between the flexible member and the orifice plate is within 15x10-6, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. It would have been obvious to a person of ordinary skill in the art to incorporate before the effective filing date of the claimed invention to incorporate wherein a difference in linear expansion coefficient between the flexible member and the orifice plate is within 15x10-6, for the purpose of providing a liquid ejecting head achieving high dimensional accuracy at a low cost (Paragraph 0018) Claim(s) 14-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oya (U.S. Pub. 2015/0283813) in view of Hayashi et al (U.S. Pub. 2020/0384773) Regarding claim 14, Hayashi discloses wherein the orifice plate is formed of a first resin layer (60; Paragraph 0030; synthetic resin) provided upright on the substrate to form a sidewall (Figure 3), and a second resin layer (55, 55a, 55b; holding frames formed of resin; Paragraph 0051) supported by the first resin layer so as to oppose the substrate, and provided with the ejection port (Figure 3) It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teaching of Hayashi into the device of Oya, for the purpose of maintaining efficient liquid ejection from the nozzles (Paragraphs 0006-0008) Regarding claim 15, Hayashi discloses wherein the flexible member (54b) is fixed on the second resin layer (55, 55a, 55b) (Figure 3; Paragraphs 0030, 0045, 0051) It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teaching of Hayashi into the device of Oya, for the purpose of maintaining efficient liquid ejection from the nozzles (Paragraphs 0006-0008) Regarding claim 16, Hayashi discloses wherein the flexible member (54b) is sandwiched and fixed between the first resin layer and the second resin layer (Figure 3; Paragraphs 0030, 0045, 0051) It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teaching of Hayashi into the device of Oya, for the purpose of maintaining efficient liquid ejection from the nozzles (Paragraphs 0006-0008) Regarding claim 17, Hayashi discloses wherein a part, which is sandwiched between the first resin layer and the second resin layer, of the flexible member is provided with a through hole (through hole is formed through holding frame and covered by damper 54b and cover 56b; Figure 3; Paragraphs 0030, 0045, 0051) It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teaching of Hayashi into the device of Oya, for the purpose of maintaining efficient liquid ejection from the nozzles (Paragraphs 0006-0008) Allowable Subject Matter Claim 10 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: The primary reason for the allowance of claim 10 is the inclusion of the limitation of wherein the first strip-shaped flexible member and the second strip-shaped flexible member are connected by a flexible member for connection. It is this limitation found in each of the claims, as it is claimed in the combination, that has not been found, taught or suggested by the prior art of record which makes these claims allowable over the prior art.
