Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 51 and 53 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claims 51 and 53, the phrases "preferably" and “in particular” renders the claims indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention.

µC2 can be either a control or evaluation electronics) Regarding claim 51, Heusser discloses: wherein the first valve section (S2) comprises at least one first actuating unit (m4) and wherein the second valve section (SX) comprises at least one second actuating unit (m5), wherein the first actuating unit (m4) and the second actuating unit (m5) are connected to a movement control unit (µC2) of the first valve section electronics module (16), wherein the first actuating unit (m4) is a first solenoid or a first electromechanical drive, and wherein the second actuating unit (m5) is a second solenoid or a second electromechanical drive (see paragraph 0040) Regarding claim 52, Heusser discloses: wherein the first valve section electronics module (16) comprises a backbone communication unit K (see paragraph 0039) Regarding claim 53, Heusser discloses: wherein the second valve section (SX) comprises a movable hydraulic closing member (12), the movable hydraulic closing member (12) is a spool piston (12), wherein the second valve section electronics module (16) comprises a second position sensor (72) for monitoring a position of the closing member 12 (see paragraph 0040) Regarding claim 54, Heusser discloses: wherein the second position sensor (72) is connected to a secondary control unit (µC2) of the first valve section electronics module 16 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 39 is/are rejected under 35 U.S.C. 103 as being unpatentable over Heusser in view of Altice et al. (U.S. 2013/0178093). Regarding claim 39, Heusser discloses the invention as essentially claimed, but fails to disclose wherein the main electronics module comprises a voltage connection and a voltage regulator, wherein a supply voltage can be applied to the valve section electronics module via an electrical backbone. Altice teaches a valve controller wherein a main electronics module (202) comprises a voltage connection and a voltage regulator (206), wherein a supply voltage can be applied to a valve section electronics module (204) via an electrical backbone (see paragraphs 0018 and 0033). It would have been obvious to one of ordinary skill in the art at the time the invention was effectively filed to have modified Heusser to provide wherein the main electronics module comprises a voltage connection and a voltage regulator, wherein a supply voltage can be applied to the valve section electronics module via an electrical backbone. Doing so would regulate the voltage to one level (see paragraph 0037), as recognized by Altice. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Arbter et al. (U.S. 2010/0211227) discloses: a hydraulic valve assembly, comprising: a connection block 14b (see paragraph 0039); at least one valve section (16, 25a, 25b, 41) hydraulically connected to the connection block 14b (see Figures 1 and 4; see paragraph 0040); a main electronics holder with a main electronics module (95) disposed therein (see paragraph 0044; see Figure 1);wherein the valve section (16, 25a, 25b, 41) comprises a valve section electronics holder (41) with a valve section electronics module (25a) disposed therein (see paragraph 0043).
