DERRICK, and CHRISTOPHER C. KENNEDY, Administrative Patent Judges. HOUSEL, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 28–41. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as nScrypt, Inc. Appeal Brief (“Appeal Br.”) filed June 12, 2018, 3. Appeal 2019-005384 Application 12/552,448 2 CLAIMED SUBJECT MATTER The invention relates to methods for dispensing various materials including high viscosity materials at high speeds. Specification (“Spec.”) filed September 2, 2009, 1:10–12.2 Claim 28, reproduced below from the Claims Appendix to the Appeal Brief, is illustrative of the claimed subject matter: 28. A method for depositing a material on a substrate in a continuous line pattern, the method comprising steps of: providing an apparatus with at least one material dispenser comprising: (i) a tip orifice defining an opening within a pen tip through which the material exits the dispenser, (ii) at least one elongate feed channel having an inlet and a spaced outlet adjacent the tip orifice, the at least one feed channel having material therein and being sized and shaped so that the material therein may flow through the at least one channel from the inlet to the outlet, (iii) a valve for controlling the flow of material through the outlet of the at least one feed channel, the valve being moveable between an open position, in which materials is permitted to flow through the outlet, and a closed position, in which material is not permitted to flow through the outlet, (iv) an actuator operatively coupled to the valve for selectively moving the valve between the open position and the closed position; positioning the pen tip at a predetermined writing gap above the substrate, the predetermined writing gap having a distance of more than 75 micrometers above the substrate, the distance being greater than a line height for the continuous line pattern such that the pen tip is positioned above the continuous line pattern; and controlling velocity of the flow of material through the outlet and dispense speed to control dispensed line height and dispensed line width parameters based on the predetermined 2 This Decision also cites to the Final Office Action (“Final Act.”) dated January 4, 2017, the Examiner’s Answer (“Ans.”) dated October 3, 2018, and the Reply Brief (“Reply Br.”) filed November 27, 2018.

OPINION We review the appealed rejections for error based upon the issues Appellant identifies, and in light of the arguments and evidence produced thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential), cited with approval in In re Jung, 637 F.3d 1356, 1365 (Fed. Cir. 2011) (“[I]t has long been the Board’s practice to require an applicant to identify the alleged error in the examiner’s rejections . . . .”). After considering the argued claims and each of Appellant’s arguments, we are not persuaded of reversible error in the appealed rejections. We offer the following for emphasis only. Rejection 1: Obviousness of claims 28, 29, 35, 40, and 41 over Warren in view of Prentice, Brown, Drumheller, and Rutkowski Appellant argues these claims as a group. We select claim 28 to address Appellant’s arguments. In accordance with 37 C.F.R. § 41.37(c)(1)(iv) (2017), claims 29, 35, 40, and 41 stand or fall with claim 28. Appeal 2019-005384 Application 12/552,448 5 The Examiner’s Position The Examiner finds that Warren teaches a method for depositing a material on a substrate so as to form a circuit or electronic components using a material dispenser substantially as recited in claim 28, wherein the pen tip is positioned at a predetermined writing gap (or vertical distance) above the substrate and the material flow rate (or velocity) is controlled in order to obtain the desired dispense line properties such as line height and width. Final Act. 3–4. The Examiner finds that Warren’s flow rate control is based on the predetermined writing gap, but acknowledges that Warren fails to disclose a range of values for the writing gap. Id. at 4–5. For this missing feature, the Examiner finds that Prentice similarly discloses a method for dispensing material on a substrate, wherein a predetermined writing gap distance between a dispenser tip and a substrate may be about 0.010–0.040 in. (254–1016 µm), so as to dispense uniform lines of viscous material onto the substrate. Final Act. 5. The Examiner further finds that Prentice teaches this predetermined writing gap to be a result-effective variable, wherein a gap that is too large negatively affects the dispensation quality and a gap that is too small results in crashes with the substrate. Id. Moreover, the Examiner finds that Prentice teaches controlling the flow rate (velocity) of the dispensed material, at a predetermined writing gap, in order to control the line dimensions (width and height) of the dispensed material. Id. As such, the Examiner finds that Prentice’s flow rate control is inherently dependent on, i.e., based on, the predetermined writing gap. Id. In addition, the Examiner finds that Brown discloses a method for dispensing material on a substrate, wherein the flow rate of dispensed Appeal 2019-005384 Application 12/552,448 6 material may be increased in response to an increase in a writing gap in order to achieve uniform dispensation of dispensed material onto the substrate. Final Act. 6. The Examiner finds that Brown provides further guidance on controlling flow rate based on a writing gap in order to achieve uniform material dispensation. Id. Therefore, based on the teachings of Prentice and Brown, the Examiner concludes that it would have been obvious, through routine optimization, to select a predetermined writing gap and control flow rate based on the writing gap in Warren’s method to allow for dispensation of uniform lines. Id. at 5–6. The Examiner next finds that Drumheller discloses a method for dispensing long lines of a material at a variety of writing speeds on a substrate, wherein the dispensed line width may be 4–12 mils (102–305 µm). Final Act. 7. The Examiner concludes that it would have been obvious to dispense long lines of material having line widths within the range recited in claim 28 (less than 300 µm) as Drumheller teaches that such widths are suitable for circuit lines and Warren discloses that the dispensed material may be circuit lines. Id. at 7–8. The Examiner further finds that Drumheller, like Warren and Prentice, discloses that writing speed may be adjusted or varied to allow for the formation of uniform lines. Final Act. 8. However, the Examiner acknowledges that these references fail to expressly teach positioning the pen tip at a height greater than the line height. Id. For this feature, the Examiner finds that Rutkowski teaches that the dispensing tip may be elevated above a line of dispensed material in order to accurately dispense a line with desired properties, including line width and height. Id. at 8–9. The Examiner concludes that it would have been obvious to set the pen tip in Appeal 2019-005384 Application 12/552,448 7 Warren’s method to be above the dispensed line height in order to allow for the dispensation of a line with certain used defined properties. Id. at 9. Appellant’s Position Appellant argues that the combination of Warren, Prentice, Brown, Drumheller, and Rutkowski fails to teach the step of controlling flow rate (velocity of the flow of material through the outlet) and dispense speed to control line width and height based on the predetermined writing gap, wherein the larger the gap, the higher the flow rate. Appeal Br. 13. Appellant contends that Warren and Brown fail to teach this step. Id. at 15. Appellant notes that Prentice positions and maintains its nozzle at a nominal height above the substrate so as to optimize the continuous dispensation of material. Appeal Br. 14. Appellant contends, however, that Prentice does not teach that greater speeds can be maintained while maintaining precise control by having a larger writing gap, nor controlling flow rate and dispense speed to control line width and height based on the gap. Id. at 14–15. Appellant also notes that Drumheller teaches a dynamic pen control system to maintain a desired dispensed line thickness to width ratio, but contends that Drumheller fails to teach this step. Appeal Br. 13–14. As to Rutkowski, Appellant notes that this reference teaches that the pen tip may be precisely located on the substrate to provide precise line width and height determined by the flow rate and dispense speed. Appeal Br. 14. However, Appellant contends that this teaching is inconsistent with Appellant’s flow rate and dispense speed control step. Id. Appeal 2019-005384 Application 12/552,448 8 Appellant next argues that a skilled artisan would not have combined Brown’s teaching with those of Warren and Prentice because Brown’s dispensing relates to spraying, not to 3D printing. Appeal Br. 15. Appellant notes that Brown is directed to a system for uniformly distributing a divergent stream of liquid onto a surface, wherein the flow rate is adjusted based on the distance between the spray nozzle and the substrate in order to provide a uniform coating of liquid. Id. at 16–17. Appellant contends that Brown is not directed to depositing a material on a substrate in a continuous line pattern. Id. at 17. Moreover, Appellant asserts that neither Warren nor Prentice are concerned with uniform distribution of liquid. Id. Finally, Appellant argues that, contrary to the Examiner’s findings of inherency, the references do not support these findings. Appeal Br. 18. In particular, Appellant asserts that the Examiner finds that Warren and Prentice inherently control flow rate based on the predetermined writing gap. Id. Appellant contends that Warren’s and Prentice’s flow rates and dispense speeds need not be based on the gap, “and the Examiner evinces nothing to indicate otherwise.” Id. at 19. Analysis Appellant’s arguments are not persuasive for the reasons the Examiner provides in the Examiner’s Answer, Response to Argument. Ans. 3–6. We note that the Examiner responds to Appellant’s arguments by directing attention to the prior Decision on Appeal (“Decision” or “Dec.”) dated January 29, 2016, which stated, contrary to Appellant’s position, that “the combined teachings of Warren and Prentice would have suggested controlling velocity of material flow and dispense speed based on Appeal 2019-005384 Application 12/552,448 9 parameters including the predetermined writing gap.” Ans. 3; Dec. 4. Appellant fails to address either the Examiner’s response or the prior Decision in this regard. Further, Appellant fails to explain with any particularity why Warren, Brown, and Drumheller fail to teach controlling velocity of material flow and dispense speed based on the writing gap. As to Appellant’s contention that Prentice fails to teach that greater speeds can be maintained while maintaining precise control by having a larger writing gap, we note that claim 28 does not recite any limitation that the dispense speed is greater when the gap is larger. However, given that Warren and Prentice suggest controlling flow rate and dispense speed based on the writing gap, one of ordinary skill in the art would reasonably conclude that greater flow rates and/or dispense speeds may be obtained for larger writing gaps through no more than routine optimization as set forth by the Examiner. Likewise, although Appellant concedes that Rutkowski teaches the pen tip may be precisely located on the substrate to provide precise line width and height determined by the flow rate and dispense speed, Appellant fails to explain with any particularity how this teaching is inconsistent with Appellant’s flow rate and dispense speed control step. We are also not persuaded that Brown is not directed to depositing a material on a substrate in a continuous line pattern or is otherwise non- analogous prior art. Appellant has not shown that Brown’s projection of a divergent stream of material to a substrate is not depositing the material on the substrate in a continuous line pattern. In fact, Brown teaches that the material is discharged continuously. Brown 3:20–33. Moreover, the Examiner finds that Brown is both in Appellant’s field of endeavor and reasonably pertinent to the particular problem with which Appellant was Appeal 2019-005384 Application 12/552,448 10 concerned. Ans. 5–6. A reference is analogous prior art if it is either in the field of the Appellant’s endeavor, or is reasonably pertinent to the particular problem with which the inventor was concerned. In re Kahn, 441 F.3d 977, 987 (Fed. Cir. 2006). The Examiner finds that Appellant’s field of endeavor is the deposition of a material onto selected areas of a substrate involving material flow control. Ans. 6. Appellant does not dispute or otherwise rebut this finding. The Examiner also finds that Brown is concerned with the problem of improving uniformity of deposited material. Id. Further, contrary to Appellant’s assertion that neither Warren nor Prentice are concerned with uniform distribution of material, the Examiner finds that both these references expressly describe that deposition uniformity is desirable. Id.; Warren ¶ 10 (“for dispensing uniform lines of viscous solutions”); Prentice ¶ 55 (“[i]n order to produce a dispense line of uniform width and cross section”). Again, Appellant does not dispute or otherwise rebut this finding. Turning to Appellant’s argument that the Examiner’s inherency findings are unsupported, the Examiner responds that the prior Decision previously supported these findings. Ans. 6. Appellant fails to address either the Examiner’s response or the prior Decision in this regard. The Examiner further explains that these positions merely indicate that these findings (that the references disclose maintaining material flows and speeds at a particular gap distance to achieve particular line height and width) read on the recited controlling flow rate and dispense speed to control line height and width based on the predetermined gap. Id. Although Appellant contends that Warren’s and Prentice’s flow rates and dispense speeds need not be based on the gap, Appellant fails to explain with any particularity why. To the contrary, the Examiner has shown that these references teach controlling Appeal 2019-005384 Application 12/552,448 11 material flow rate and dispense speed, and also that Prentice teaches that the writing gap is a result effective variable wherein “control of velocity and speed necessarily is based on the particular value of this . . . writing gap.” Dec. 4. The Board previously held, “[t]hese findings and the corroborative technical reasoning identified in the Final Action and in the Answer convincingly support the Examiner’s determination that the combined teachings of Warren and Prentice would have suggested controlling velocity of material flow and dispense speed based on parameters including the predetermined writing gap.” Id. Appellant fails to persuasively identify any reason why we should deviate from the Board’s holding.3 3 In the Reply Brief, Appellant presents a new argument not raised in the Appeal Brief concerning Prentice, i.e., that Prentice never discusses a writing gap but merely relies upon a “nominal clearance height.” Reply Br. 27–28. Under regulations governing appeals to the Board, any new argument not timely presented in the Appeal Brief will not be considered when filed in a Reply Brief, absent a showing of good cause explaining why the argument could not have been presented in the Appeal Brief. See 37 C.F.R. § 41.41(b)(2); In re Hyatt, 211 F.3d 1367, 1373 (Fed. Cir. 2000) (noting that an argument not first raised in the brief to the Board is waived on appeal); Ex parte Nakashima, 93 USPQ2d 1834 (BPAI 2010) (explaining that arguments and evidence not timely presented in the principal Brief will not be considered when filed in a Reply Brief, absent a showing of good cause explaining why the argument could not have been presented in the Principal Brief); Ex parte Borden, 93 USPQ2d 1473, 1477 (BPAI 2010) (informative) (“Properly interpreted, the Rules do not require the Board to take up a belated argument that has not been addressed by the Examiner, absent a showing of good cause.”). Appellant has provided this record with no such showing. Indeed, given the importance of Prentice with regard to the issue of writing gap, e.g., that Prentice teaches that the writing gap is a result effective variable, there would seem to be no excuse for failing to raise this issue earlier in the prosecution of this application. Accordingly, we will not consider this new argument in the Reply Brief. Appeal 2019-005384 Application 12/552,448 12 Accordingly, we sustain the Examiner’s rejection of claims 28, 29, 35, 40, and 41 under 35 U.S.C. § 103(a) as unpatentable over Warren in view of Prentice, Brown, Drumheller, and Rutkowski. Rejections 2–5: Obviousness of claims 30–34 and 36–39 over Warren in view of Prentice, Brown, Drumheller, and Rutkowski, and further in view of Lord, Bremner, Lemmo, Churchill, or Gibson Appellant argues that Lord fails to remedy the deficiencies in the combination of Warren, Prentice, Brown, Drumheller, and Rutkowski as applied to claim 28. Appeal Br. 20. Appellant does not separately argue the rejections relying on Bremner, Lemmo, Churchill, or Gibson. Because we are not persuaded of any deficiency in the Warren, Prentice, Brown, Drumheller, and Rutkowski combination as applied to claim 28 requiring curing by Lord (or the remaining applied prior art), we are not persuaded of reversible error in any of Rejections 2–5. Accordingly, we sustain each of obviousness Rejections 2–5. CONCLUSION Upon consideration of the record and for the reasons set forth above and in the Final Office Action and the Examiner’s Answer, the Examiner’s decision to reject claims 28–41 under 35 U.S.C. § 103(a) is affirmed.
