Accordingly, the information disclosure statement is being considered by the examiner. 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 1, 11, 18, and 20 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 1, 11, and 18, the examiner is unsure how the invention is supposed to know the “linear actuator” is supposed to move? How is the invention supposed to know when the “linear actuator” needs to move the “retractable printhead shield”? Furthermore, the examiner is unsure what component is supposed to help the “linear actuator” move the “retractable printhead shield”? Regarding claim 20, the examiner is unsure how does the invention of the method know which “inkjets” are used and which are unused? What determines an inkjet as “used” or “unused”? How does the invention of the method know when to eject “one or more ink droplets from the plurality of unused inkjets” and when to continue printing on the “print media substrate”? 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.

Therefore, it would be obvious for someone with ordinary skill in the art before the effective filing date of the claimed invention to modify the inkjet printing system taught by Somete to also apply a linear actuator coupled to the retractable printhead shield and configured to slide the retractable printhead shield under the one or more frames taught by Gomez. This would have been done for the purpose of allowing the plurality of printheads to be covered (Gomez, paragraph [0005]). Regarding claim 2, a controller (“controller 50”, Figure 8) operatively connected to the linear actuator (“actuator 218”, Figure 1). Therefore, it would be obvious for someone with ordinary skill in the art before the effective filing date of the claimed invention to modify the inkjet printing system taught by Somete to also apply a controller operatively connecting to the actuator taught by Gomez. This would have been done for the purpose of giving the printer the ability to actuate the actuator through the controller (Gomez, paragraph [0005]). Regarding claim 11, a linear actuator coupled (“actuator 218”, Figure 1) to the retractable printhead shield (“printhead seal assembly 212”, Figure 1) and configured to slide the retractable printhead shield under the one or more frames in a direction perpendicular to a process direction (Paragraph [0020] describes how the “printhead seal assembly 212” that seals the “printhead surface” is moved using the “actuator 218”.). Therefore, it would be obvious for someone with ordinary skill in the art before the effective filing date of the claimed invention to modify the print bar assembly taught by Somete to also apply a linear actuator coupled to the retractable printhead shield and configured to slide the retractable printhead shield under the one or more frames taught by Gomez. This would have been done for the purpose of allowing the plurality of printheads to be covered (Gomez, paragraph [0005]). Somete and Gomez fail to disclose the following limitations: Regarding claim 10, the inkjet printing system of claim 1, wherein second surface of the printhead mounting plate is spaced less than 5 mm vertically apart from the media transport system, and wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm. The combination of Somete and Gomez discloses the claimed invention except for applying wherein second surface of the printhead mounting plate is spaced less than 5 mm vertically apart from the media transport system, and wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm. It would have been obvious to one having ordinary skill in the art at the time the invention was made to apply wherein second surface of the printhead mounting plate is spaced less than 5 mm vertically apart from the media transport system, and wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). Regarding claim 17, the print bar assembly of claim 11, wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm. The combination of Somete and Gomez discloses the claimed invention except for applying wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm. It would have been obvious to one having ordinary skill in the art at the time the invention was made to apply wherein the retractable printhead shield is a thin planar sheet having a thickness of less than 1 mm, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). Claim(s) 3-5 and 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over the combination of Somete and Gomez as applied to claim 1 above, and further in view of Takamichi et al. (JP 2005074763 A) Somete disclose the following limitations: Regarding claim 3, the inkjet printing system of claim 2, wherein the position of the retractable printhead shield (“cap unit 31”, Figure 3). Regarding claim 4, the inkjet printing system of claim 3, wherein the controller (“control part 2”, Figure 2) is configured to (i) determine an unused portion of the one or more printheads received by the one or more frames, and (ii) adjust the position of the retractable printhead shield to cover the unused portion of the one or more printheads (Paragraphs [0052]-[0053] describe how the “control part 2” executes the “operation of the maintenance device 30” when it determines that an image forming job has not been executed for a “predetermined period”. Therefore, the “control part 2” can determine when one or more printheads are not being used. Furthermore, once the “control part 2” determines the one or more printheads are not being used, the execution of the maintenance operation includes moving the “cap unit 31” of the “maintenance device 30” to cover the “head unit 11”.). Regarding claim 5, the inkjet printing system of claim 1, wherein the retractable printhead shield (“cap unit 31”, Figure 3). Somete fails to disclose the following limitations: Regarding claim 3, the inkjet printing system of claim 2, wherein the position of the retractable printhead shield is adjusted based on a width of the print media substrate moving through the printing zone.
