Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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 10 is rejected under 35 U.S.C. 103 as being unpatentable over Harald (EP1008388A1 attached NPL, English Machine translation). Regarding claim 10, Harald does not explicitly disclose one or more slide channels oriented parallel to the first linear path, wherein actuation of the first rail assembly is guided by the one or more slide channels; However, Harald disclose one or more slides oriented parallel to the first linear path, wherein actuation of the first rail assembly is guided by the one or more slide (paragraphs 0034, 0043 and 45); and The crusher including the necessary frames and supports (paragraph 0022); Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to select the type of slides as desired, including one or more slide channels oriented parallel to the first linear path, wherein actuation of the first rail assembly is guided by the one or more slide channels; in order to have the blades sliding against each other, exerting a horizontal shearing effect (Harald: paragraph 0034) Claim 11-15 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Harald (EP1008388A1 attached NPL, English Machine translation) in view of Tanaka (US20050173570A1). Regarding claim 11, Harald discloses a pulverizer system, comprising: a first rail assembly (paragraph 0051 and figs.1-2: (1)) including a first plurality of rails extending along a first plane (figs.2-3), each of the first plurality of rails separated from each other by first gaps and the first plurality of rails including at least one rail tooth (figs.2-3); a second rail assembly (paragraph 0051 and figs.1-22: (2)) including a second plurality of rails extending along a second plane (figs.2-3), each of the second plurality of rails separated from each other by second gaps, the first plurality of rails receivable in the second gaps and the second plurality of rails receivable in the first gaps (figs.2-3); a first linear actuator secured to the first rail assembly, the first linear actuator actuatable along a first linear path to urge the first rail assembly at least partially through the second gaps of the second rail assembly (figs.1-3; paragraphs 0019, 0022, 0028, 0034 and 0051); a second linear actuator secured to the second rail assembly, the second linear actuator actuatable along a second linear path to urge the second rail assembly at least partially through the first gaps of the first rail assembly (figs.1-3; paragraphs 0019, 0022, 0028, 0034 and 0051); Harald does not disclose a prime mover, wherein the prime mover wherein the prime mover provides power to one or more of the first linear actuator and the second linear actuator. Tanaka teaches a prime mover (fig.19: (181)), wherein the prime mover provides power to one or more of a first actuator and a second actuator (fig.19: (169, 173, 174, 176, 177)) (paragraphs 0009 and 0155-00159). Both of the prior arts of Harald and Tanaka are related to a pulverizer system having jaw crushers, Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Harald to have a prime mover, wherein the prime mover provides power to one or more of a first actuator and a second actuator as taught by Tanaka in order to provides that baseline mechanical energy, which a hydraulic pump then converts into pressurized fluid energy; thereby having a prime mover, wherein the prime mover wherein the prime mover provides power to one or more of the first linear actuator and the second linear actuator. Regarding claim 12, Harald discloses one or more side walls including a top end and a bottom end (figs.1-2: see the side walls of elements (1) and (2)), the one or more side walls defining a first opening (fig.1: the top opening between elements (1) and (2)) located at the top end of the one or more side walls and a second opening located at the bottom end of the one or more side walls (fig.1: the bottom opening between elements (1) and (2)), wherein solid waste material is insertable into the first opening, and wherein processed waste material exits the pulverizer system through the second opening (paragraphs 0022 and 0036). Therefore, the modification of Harald in view of Tanaka teaches the limitations of claim 12. Regarding claim 13, Harald discloses wherein the first rail assembly and the second rail assembly each include a plurality of teeth, wherein the plurality of teeth is configured to pulverize solid waste material into processed waste material (figs.1-3). Therefore, the modification of Harald in view of Tanaka teaches the limitations of claim 13. Regarding claims 14-15, Harald does not disclose an electronic control unit (ECU) in communication with one or more of the first linear actuator, the second linear actuator, and the prime mover, the ECU configured to control a timing of the first linear actuator and the second linear actuator; wherein the ECU selectively distributes the power from the prime mover to the first linear actuator and the second linear actuator. Tanaka teaches an electronic control unit (ECU) (fig.19: (205)) in communication with one or more of the first actuator, the second actuator, and the prime mover, the ECU configured to control a timing of the first linear actuator and the second linear actuator; wherein the ECU selectively distributes the power from the prime mover to the first actuator and the second actuator (figs.19-25; paragraphs 0216-245); Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Harald to have an electronic control unit (ECU) in communication with one or more of the first actuator, the second actuator, and the prime mover, the ECU configured to control a timing of the first linear actuator and the second linear actuator; wherein the ECU selectively distributes the power from the prime mover to the first linear actuator and the second linear actuator as taught by Tanaka since it has been held that combining prior art elements according to known methods to yield predictable results requires only routine skill in the art. [KSR Int’l Co. v. Teleflex Inc., 127 S.Ct. 1727, 1742, 82 USPQ2d 1385, 1396 (2007)]; thereby having an electronic control unit (ECU) in communication with one or more of the first linear actuator, the second linear actuator, and the prime mover, the ECU configured to control a timing of the first linear actuator and the second linear actuator; wherein the ECU selectively distributes the power from the prime mover to the first linear actuator and the second linear actuator. Regarding claim 17, Harald does not disclose a conveyer belt assembly located at the second opening, wherein the processed waste material is receivable on the conveyer belt assembly. Tanaka teaches a conveyer belt assembly located at a second opening, wherein the processed material is receivable on the conveyer belt assembly (paragraph 0040). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Harald to have a conveyer belt assembly located at a second opening, wherein the processed material is receivable on the conveyer belt assembly as taught by Tanaka since it has been held that combining prior art elements according to known methods to yield predictable results requires only routine skill in the art. [KSR Int’l Co. v. Teleflex Inc., 127 S.Ct. 1727, 1742, 82 USPQ2d 1385, 1396 (2007)]; thereby having a conveyer belt assembly located at the second opening, wherein the processed waste material is receivable on the conveyer belt assembly. Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Harald (EP1008388A1 attached NPL, English Machine translation) in view of Tanaka (US20050173570A1) as applied to claim 15 above, and further in view of Janne (WO2000025926A1) Regarding claim 16, Harald in view of Tanaka does not disclose a force sensor in one or more of the first linear actuator and the second linear actuator, wherein the ECU may selectively control an ON/OFF state based on data received from the force sensor. Janne discloses a force sensor in one or more of a first actuator and a linear actuator, wherein a ECU may selectively control an ON/OFF state based on data received from the force sensor (abstract and claim 1 and claim 7). Both of the prior arts of Harald and Janne are related to a pulverizer system having jaw crushers, Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Harald in view of Tanaka to have a force sensor in one or more of a first actuator and a linear actuator, wherein a ECU may selectively control an ON/OFF state based on data received from the force sensor as taught by Janne, since it has been held that combining prior art elements according to known methods to yield predictable results requires only routine skill in the art. [KSR Int’l Co. v. Teleflex Inc., 127 S.Ct. 1727, 1742, 82 USPQ2d 1385, 1396 (2007)]; thereby having a conveyer belt assembly located at the second opening, wherein the processed waste material is receivable on the conveyer belt assembly.
