SMITH, KAREN M. HASTINGS, and MICHAEL P. COLAIANNI, Administrative Patent Judges. SMITH, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF CASE Appellant appeals under 35 U.S.C. § 134 from the Examiner's decision to reject claims 1-3, 5-10, 12-24, 27-30, 45--48 and 55. We have jurisdiction under 35 U.S.C. § 6(b). Appeal2014-007134 Application 11/573,666 The claimed invention is directed to a method for creating a silicone shell. App. Br. 3. Claim 1 illustrates the subject matter on appeal and is reproduced below: 1. A method for creating a silicone shell, the method comprising: a) providing a mandrel suitably sized and shaped for forming a desired shell for an implantable mammary prosthesis; b) applying a first coating of a silicone dispersion to the mandrel by spraying the silicone dispersion at less than 15 psi to create a shell having a desired thickness, wherein the silicone dispersion having a defined percent solids; c) partially curing the silicone shell for 10 to 20 minutes in a devolatilization step between applying the first coating and a second coating of the silicone dispersion to the mandrel, without allowing the silicone to fully cure, the first coating and the second coating of silicone being applied by an electrostatically operated rotary atomizer configured to control applying silicone to both an entirety of the mandrel and a portion thereof; and d) removing the silicone shell from the mandrel. Appellant requests review of the following rejections from the Examiner's Final Office Action: I. Claims 1-3, 5, 7, 12, 14--16, 28, and 45--47 rejected under 35 U.S.C. § 103(a) as being unpatentable over Dogan et al., (US 5,630,844, issued May 20, 1997), Iversen et al., (US 5,961,552, issued October 5, 1999), Stephenson et al., (US 2003/0197311 Al, published October 23, 2003), Leidner et al., (US 6,056,993, issued May 2, 2000) and Hufstetler et al., (US 4,761,299, issued August 2, 1988). 1 1 The Examiner denominated this rejection as a new ground in the Answer because the statement of rejection erroneously omitted the reference to Iversen. Ans. 13. Therefore, for the purposes of this opinion, we refer to the 2 Appeal2014-007134 Application 11/573,666 IL Claim 48 rejected under 35 U.S.C. § 103(a) as being unpatentable over Dogan, Iversen, Stephenson, Leidner, Hufstetler and Frisch (US 4,992,312, issued February 12, 1991). III. Claims 1-3, 6-10, 12-24, and 27-30 rejected under 35 U.S.C. § 103(a) as being unpatentable over Falcon et al., (US 2002/0143396 Al, published October 3, 2002), Prewett (US 2005/0216094 Al, published September 29, 2005), Iversen, Stephenson, Leidner, and Hufstetler. OPINION2 The Prior Art Rejections3 After review of the respective positions provided by Appellant and the Examiner, we AFFIRM the Examiner's prior art rejections under 35 U.S.C. § 103(a) for the reasons presented by the Examiner and add the following for emphasis. Independent claim 1 is directed to a method for creating a silicone shell by spraying silicone dispersion coatings on a mandrel at less than 15 psi to create a shell having a desired thickness and partially curing the silicone shell between application of coatings. Answer and the Reply Brief for the respective positions of the Examiner and Appellant with respect to this rejection. 2 For Rejections I and III, Appellant argue independent claims 1 and 2 together and do not present separate arguments for any dependent claim. Reply Br. 3; App. Br. 11. Further, in addressing the separate rejection of claim 48 (Rejection II), Appellant relies on the arguments presented in Rejection I when discussing independent claim 1. App. Br. 11. Accordingly, we select claim 1 as representative of the subject matter before us on appeal and limit our discussion to this claim. Independent claim 2 and all dependent claims stand or fall with independent claim 1. 3 Appellant relies on common arguments in addressing Rejections I and II. See Appeal Brief and Reply Brief, generally. Accordingly, we address these rejections together in the opinion. 3 Appeal2014-007134 Application 11/573,666 The Examiner found the prior art, as represented by Dogan, Falcon and Prewett, discloses as known to form a silicone shell for a mammary prosthesis by providing a suitably shaped mandrel for forming the desired shell, coating a silicone dispersion having a defined percent solids onto the mandrel, setting the applied coating, and removing the shell from the mandrel. Ans. 13-14; Final Act. 8; Dogan Abstract, col. 4, 11. 42--43, col. 8, 11. 30-60; Falcon i-fi-f l, 9, 17, 29; Prewett i-fi-f 18, 38. The Examiner relied on Iversen to establish Dogan's heat setting of the silicone dispersion at 130 °F and Falcon's partial curing of Falcon are partial curing steps resulting in devolatization of the solvent in the silicone rubber dispersion. Ans. 14--15; Final Act. 9; Iversen col. 7, 11. 44--col. 8, 11. 25. The Examiner also found the prior art, as represented by the teachings of Stephenson and Leidner, disclose as well known to electrostatically spray coat a silicone or elastomeric dispersion onto a mandrel to form an article, with Stephenson disclosing the use of an electrostatic rotary atomizer as an alternative to dip coating to accomplish this goal. Ans. 14--16; Final Act. 10-11; Dogan col. 8, 11. 60-65; Stephenson i-fi-f 10, 18, 19, 27; Leidner Abstract, col. 2, 11. 33- 4 7. The Examiner concluded that it would have been obvious to one having ordinary skill in the art to spray coat the elastomeric dispersion of either Dogan or Falcon to a mandrel using an electrostatic rotary atomizer in view of the teachings of Stephenson and Leidner. Ans. 16; Final Act. 11. The Examiner found Stephenson and Leidner do not disclose electrostatically spraying the silicone dispersion at less than 15 psi to create a shell. Ans. 17; Final Act. 11. However, the Examiner found Hufstetler discloses it was known to operate a high volume low pressure electrostatic atomizer/sprayer at an air pressure of less than 15 psi to coat the surface to ensure higher 4 Appeal2014-007134 Application 11/573,666 transfer etliciency as compared to conventional spray guns. Ans. 17; Final Act. 12; Hufstetler Abstract, col. 4, 11. 50-53. The Examiner determined it would have been obvious to one having ordinary skill in the art to apply the elastomeric dispersion of Dogan and Falcon using an electrostatic atomizer at pressures of less than 15 psi for the reasons taught by Hufstetler' s disclosure. Ans. 17; Final Act. 12. Appellant argues the subject matter distinguishes the claimed invention from dip casting methods because the claims recite the silicone dispersion having a defined percent solids as opposed to a defined viscosity. Reply Br. 7. We are unpersuaded by this argument. As noted by the Examiner, Dogan discloses spray coating the silicone dispersion having defined solids contents onto a mandrel to form the silicone shell. Ans. 14; Dogan col. 8, 11. 60-65. The Examiner also found Stephenson discloses electrostatically spraying an elastomeric dispersion onto a mandrel as an alternative to a dipping process. Ans. 16; Stephenson i-f 8. Thus, the Examiner provided a reasonable basis for one skilled in the art to use electrostatic spraying to form the silicone shell on a mandrel instead of the dipping process. Appellant has not adequately explained why one skilled in the art would not have been capable of adapting the methods of forming silicone shells of either Dogan or Falcon by using the electrostatic spraying method of Stephenson and Leidner to coat the mandrel given the disclosures of Dogan and Stephenson. While Appellant argues there is no recognition whatsoever in the art that a silicone shell could be produced using electrostatic sprayers at the claimed pressures, Appellant has not adequately explained why one skilled in the art would not have been capable of determining the appropriate 5 Appeal2014-007134 Application 11/573,666 operating pressure to maximize coating etliciency, as disclosed by Hufstetler. Reply Br. 10; Ans. 17, 20; Final Act. 12; Hufstetler Abstract, col. 4, 11. 50-53. See In re Sovish, 769 F.2d 738, 743 (Fed. Cir. 1985) (skill is presumed on the part of one of ordinary skill in the art); In re Bozek, 416 F.2d 1385, 1390 (CCPA 1969). Appellant argues the claims are directed to forming a mammary prosthesis and, thus, are distinguishable from the cited references (Stephenson, Leidner and Hufstetler) that are unrelated to this subject matter. Reply Br. 7. Appellant further argues the prior art cannot be properly combined to teach the claimed subject matter without using improper hindsight. Reply Br. 7-8. We are again unpersuaded. The Examiner found Stephenson and Leidner disclose as known to us electrostatic spraying for the purpose of spraying an elastomeric dispersion onto a mandrel. Ans. 14--16; Final Act. 10-11; Dogan col. 8, 11. 60-65; Stephenson i-fi-f 10, 18, 19, 27; Leidner Abstract, col. 2, 11. 33--47. The Examiner also found Hufstetler discloses as known to operate electrostatic spraying devices at pressures within the claimed range to ensure efficient coating. Ans. 17; Final Act. 12; Hufstetler Abstract, col. 4, 11. 50-53. We find no error in the Examiner's determination that these references would have led one skilled in the art to apply a silicone dispersion over a mandrel using an electrostatic spraying device because Appellant's arguments do not address the Examiner's reasons for relying on the references. Ans. 13-15. Appellant argues the Examiner provided no objective reasoning for incorporating the Iversen' s partial curing of the elastomeric dispersion into the methods of Dogan and Falcon. Reply Br. 7-8; App. Br. 14--15. 6 Appeal2014-007134 Application 11/573,666 We are unpersuaded by this argument as well. Contrary to Appellant's argument, the Examiner did not propose to incorporate the teachings of Iversen. As noted above, the Examiner relied on Iversen to establish Dogan's heat setting of the silicone dispersion at 130 °F and Falcon's partial curing are partial curing steps resulting in devolatization of the solvent in the silicone rubber dispersion. Ans. 14--15; Final Act. 9; Iversen col. 7, 11. 44--col. 8, 11. 25. Appellant's argument does not address the reasons for which the Examiner relied on Iversen. Accordingly, we sustain the Examiner's prior art rejections of claims 1-3, 5-10, 12-24, 27-30, 45--48, and 55 under 35 U.S.C. § 103(a) for the reasons presented by the Examiner and given above. ORDER The Examiner's prior art rejections of claims 1-3, 5-10, 12-24, 27- 30, 45--48, and 55 under 35 U.S.C. § 103(a) are affirmed. TIME PERIOD No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l). AFFIRMED 7 Copy with citationCopy as parenthetical citation
