PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE ____________ BEFORE THE BOARD OF PATENT APPEALS AND INTERFERENCES ____________ Ex parte RICHARD HART LUXTON ____________ Appeal 2010-002677 Application 11/337,759 Technology Center 3700 ____________ Before SALLY G. LANE, RICHARD M. LEBOVITZ, and SCOTT R. BOALICK, Administrative Patent Judges. LEBOVITZ, Administrative Patent Judge. DECISION ON APPEAL Appeal 2010-002677 Application 11/337,759 2 This is a decision on the appeal under 35 U.S.C. § 134 by the Patent Applicant from the Patent Examiner’s rejections of claims 28-48 in U.S. Application 11/337,759. The Board’s jurisdiction for this appeal is under 35 U.S.C. §§ 6(b). We affirm. BACKGROUND The claims are directed to a safety razor blade unit comprising a plurality of main cutting edges and a “further cutting edge” at the rear of the unit. The “further cutting edge” has a passage for “through flow of rinsing water.” According to the patent application, the passage “allows effective removal of soap and shaving debris from the underside of the blade so that the performance of this blade will not be impaired by a space on the underside of the blade clogging up.” (Spec. ¶ [008].) The claims stand rejected by the Examiner as follows: 1. Claims 28-33 and 36 under 35 U.S.C. § 103(a) as obvious over Brown1 in view of GP ‘486,2 Rodrigues,3 Meyer,4 Sellera,5 or Asano,6 2. Claims 34, 35, and 37-48 under 35 U.S.C. § 103(a) as obvious over Brown in view GP ‘486, Rodrigues, Meyer, Sellera, or Asano, and further in view of Apprille,7 3. Claims 28-33 and 36 under 35 U.S.C. § 103(a) as obvious over 1 U.S. Patent App. Pub. 2004/0055156 A1 published Mar. 25, 2004. 2 DE 3733486 A1 published Apr. 20, 1989. 3 U.S. Patent No. 2,048,565 issued July 21, 1936. 4 U.S. Patent No. 3,138,865 issued June 30, 1964. 5 U.S. Patent No. 4,077,119 issued Mar. 7, 1978. 6 U.S. Patent No. 4,265,015 issued May 5, 1981. 7 U.S. Patent No. 6,044,542 issued Apr. 4, 2000. Appeal 2010-002677 Application 11/337,759 3 Rozenkranc8 in view of GP ‘486, Rodrigues, Meyer, Sellera, or Asano; and 4. Claims 34, 35, 37-42, 43-45, and 46-48 under 35 U.S.C. § 103(a) as obvious over Rozenkranc in view GP ‘486, Rodrigues, Meyer, Sellera, or Asano, and further in view of Apprille. Claim 28 is representative and reads as follows: 28. A safety razor blade unit comprising an upper face, a bottom face, a front face and a rear face, a plurality of cutting edges positioned between a first guard surface and a first cap surface at the upper face, and a further cutting edge positioned between a second guard surface and a second cap surface at the rear face, a distance between the first guard surface and the first cap surface, measured in a plane tangential thereto, being greater than a distance between the second guard surface and the second cap surface, measured in a plane tangential thereto, and wherein a passage for through flow of rinsing water connects a gap between the further cutting edge and the second guard surface with an opening at the bottom face. DISCUSSION The facts are not in dispute in this appeal. The Brown and Rozenkranc publications were found by the Examiner to describe a safety razor with almost all the features of the claimed safety razor blade unit, but not with a rinse-through passage for the trimming blade (the “further cutting edge”) as recited in claim 28 (Ans. 4 & 9). However, the Examiner found this element to have been described in GP ‘486, Rodrigues, Meyer, Sellera, and Asano. The Examiner determined it would have been obvious to include a rinse-through passage for the trimming blade since “such passages 8 U.S. Patent No. 6,276,061 B1 issued Aug. 21, 2001. Appeal 2010-002677 Application 11/337,759 4 are old and well known” and have the “benefit” of “facilitating cleaning” of the blade after shaving (Ans. 5 & 9-10). Appellant contends that the concept of passages for “through flow of rinsing water” was readily available to both Brown and Rozenkranc, but neither “elected” to use a rinse-through passage for the additional trimming blade (Br. 5 & 7). Rather, Appellant contends that each of Brown and Rozenkranc utilized rinse-through passages for the primary blade, but not the trimming blade (id.). Thus, Appellant argues the skilled worker would have been led away from the idea of providing a rinse-through passage for the trimming blade (id.). Appellant also contends that a trimming blade would cut considerably less hair than the main shaving blades, and that the benefit of a rinse-through passage for it would not have been apparent to the ordinary skilled worker (id.). The fact that rinse-through passages were available to Brown and Rozenkranc, but not utilized for their trimming blades does not constitute a teaching away from the claimed subject matter. Appellant has not invoked the proper standard of obviousness. Under 35 U.S.C. § 103(a): A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Thus, obviousness is determined through the eyes of “a person having ordinary skill in the art.” The issue in these rejections is whether the Appeal 2010-002677 Application 11/337,759 5 ordinary skilled worker would have had reason to use a rinse-through passage in the trimming blade of Brown and Rozenkranc, not whether Brown or Rozenkranc individually made or suggested such a modification to their invention. The Examiner provided a logical and fact-based reason as to why the skilled worker would have incorporated a rinse-through passage into the trimming blade of Brown and Rozenkranc (Ans. 5 & 9-10). Appellant has not identified disclosure in either publication that would have dissuaded the skilled worker from having made such a modification, other than the fact that rinse-through passages were available to Brown and Rozenkranc, but not used by them for the trimming blade. Nor has the Appellant directed us to other evidence that might show that the prior art taught away from the modification. See Spectralytics, Inc. v Cordis Corp., 99 USPQ2d 1012, 1017 (Fed. Cir. 2011) (“It is indeed of interest if the prior art warned against the very modification made by the patentee, but it is not the sole basis on which a trier of fact could find that the prior art led away from the direction taken by the patentee. Instead, the jury could find, based on the expert testimony, that prior Swiss-style machines taught away from embracing vibrations to improve cutting accuracy because all prior machines improved accuracy by dampening vibrations [footnote omitted].”). This, alone, is insufficient to rebut obviousness since an inventor is free to describe the subject matter he or she regards as his invention with the features he or she so chooses. There may be a variety of reasons as to why Brown and Rozenkranc did not include a rinse-through passage for the trimming blade, but without additional evidence, this omission is not Appeal 2010-002677 Application 11/337,759 6 sufficient basis to infer the nonobviousness of it, rather than some other reason. Appellant also contends that it would have not have been obvious to have placed a rinse-through passage underlying the trimming blade because it would accumulate considerable less hair than the main blades. This argument is not persuasive. As long as there is some hair present, the blade would require cleaning and the Examiner’s logic that a passageway would facilitate cleaning still holds. Obviousness rejections 1 and 3 of claim 28 are affirmed. Rejections 2 and 4 are affirmed for the reasons set forth by the Examiner. Claims 29-48 were not separately argued, and therefore fall together. 37 C.F.R. § 41.37(c)(1)(vii). See Br. 6 & 8. TIME PERIOD FOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
