DECISION ON APPEAL1 1 The two-month time period for filing an appeal or commencing a civil action, as recited in 37 C.F.R. § 1.304, or for filing a request for rehearing, as recited in 37 C.F.R. § 41.52, begins to run from the “MAIL DATE” (paper delivery mode) or the “NOTIFICATION DATE” (electronic delivery mode) shown in the PTOL-90A cover letter attached to this decision. Appeal 2009-009157 Application 11/082,002 2 STATEMENT OF THE CASE Todd A. Hagan (Appellant) appeals under 35 U.S.C. § 134 from the Examiner’s decision finally rejecting claims 14-16, 18-21, and 23 under 35 U.S.C. § 102(b) as anticipated by Weinstein (U.S. Patent No. 5,558,264, issued Sep. 24, 1996). The Examiner objected to claims 8-10, 17, and 22 as being dependent upon a rejected base claim, but as otherwise allowable if rewritten in independent form to include the subject matter of the base claim and any intervening claims. On Jan. 12, 2009, the Examiner issued an Examiner’s Amendment cancelling claims 1-7 and 11-13 pursuant to an Order Returning Undocketed Appeal to Examiner mailed Dec. 24, 2008. In addition, the Examiner withdrew the nonstatutory obviousness-type double patenting rejection in consideration of the filing of a Terminal Disclaimer. We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. The Invention The claims on appeal relate to a fastening tool including a housing assembly and a magazine assembly. The housing assembly includes a nosepiece. The magazine assembly is coupled to the housing assembly and includes a canister configured to hold a plurality of collated fasteners. Claims 14 and 19, reproduced below in pertinent part and with emphasis added, are representative of the subject matter on appeal. 14. A fastening tool comprising: . . . . ; and a feeder pawl assembly coupled to the magazine assembly and including a feed pawl and a spreader pawl, the feed pawl movable to engage a first fastener of the collated fasteners and advance the first fastener into the nosepiece during a feed motion, the spreader pawl locating between a pair of subsequent fasteners of the collated Appeal 2009-009157 Application 11/082,002 3 fasteners and at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion. 19. A fastening tool comprising: . . . . a plurality of collated fasteners; . . . .; and a feeder pawl assembly coupled to the magazine assembly and comprising: a feed pawl having a feed tooth for locating a feed tooth width between a first pair of adjacent fasteners, the feed tooth operable in a feed direction to advance a fastener of the first pair toward the nosepiece during a feed motion; and a spreader pawl having a spreader tooth adapted to locate between a first gap defined between a second pair of adjacent fasteners, the first gap being smaller than the feed tooth width, the spreader pawl resisting movement of an engaged fastener of the second pair in the feed direction during the feed motion and thereby defining a second gap between the second pair of adjacent fasteners, the second gap having a space suitable to accept the feed tooth width of the feed tooth therebetween. OPINION Issues The determinative issues in this appeal are: (1) Did the Examiner err in interpreting Weinstein to disclose a “spreader pawl . . . at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion” (App. Br., Claims App’x.) as recited in claim 14? Appeal 2009-009157 Application 11/082,002 4 (2) Did the Examiner err in interpreting Weinstein to disclose a “spreader pawl resisting movement of an engaged fastener of the second pair in the feed direction during the feed motion and thereby defining a second gap between the second pair of adjacent fasteners, the second gap having a space suitable to accept the feed tooth width of the feed tooth therebetween” (App. Br., Claims App’x.) as recited in claim 19? Analysis Issue 1 Appellant contends that the spreader pawl or holding claw 250 of Weinstein does not satisfy claim 14’s language of “at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion” (App. Br., Claims App’x.) because “the holding claw (250) simply pivots out of the way of the nails (N) that are advanced in the feed direction.” App. Br. 7. More particularly, Appellant contends that “[t]he holding claim [sic: claw] (250) only engages a fastener at FIGS. 4 and 5 to resist movement of the nail (N) in a direction opposite the feed direction; and at FIG. 6 when it ramps over the same fastener being fed (i.e. not a subsequent fastener as provided in claim 14).” 2nd Reply Br. 2.2 2 On Apr. 24, 2008, Appellant filed a Reply Brief (1st Reply Br.) in response to the Examiner’s Answer (1st Ans.) mailed Feb. 28, 2008. On Dec. 24, 2008, an Order Returning Undocketed Appeal to Examiner (Order) was mailed requiring the Examiner to cancel claims in accordance with Ex parte Ghuman and to consider a Terminal Disclaimer filed on Nov. 29, 2007. The Examiner responded to the Order with an Examiner’s Amendment mailed Jan. 12, 2009 and a second Examiner’s Answer (2nd Ans.) mailed Mar. 30, 2009. On May 5, 2009, Appellant filed a second Reply Brief (2nd Reply Br.) in response to the second Examiner’s Answer. Appeal 2009-009157 Application 11/082,002 5 The Examiner’s position is that Weinstein anticipates claim 14 and points to column 5, lines 25-40 as providing support for the language of “the spreader pawl locating between a pair of subsequent fasteners of the collated fasteners and at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion.” 2nd Ans. 4. As noted above, Appellant argues that Weinstein does not perform the same function as the claimed invention. See App. Br. 7. The Examiner argues that Weinstein clearly shows all of the recited structural features including a spreader pawl “clearly capable of resisting or partially inhibiting movement of one of the adjacent fasteners toward the nosepiece in a feed direction during the feed operation.” 2nd Ans. 5. The Examiner then posits that “[w]hile it is noted that the device of Weinstein may not perform the same function or in the same manner as [Appellant’s] invention, it is deemed that the claims are not restrictive to such device.” Id. A patent applicant is free to recite features of an apparatus either structurally or functionally. See In re Swinehart, 439 F.2d 210, 212 (CCPA 1971) (“[T]here is nothing intrinsically wrong with [defining something by what it does rather than what it is] in drafting patent claims.”). As stated in Swinehart, 439 F.2d at 213: [W]here the Patent Office has reason to believe that a functional limitation asserted to be critical for establishing novelty in the claimed subject matter may, in fact, be an inherent characteristic of the prior art, it possesses the authority to require the applicant to prove that the subject matter shown to be in the prior art does not possess the characteristic relied on. Appeal 2009-009157 Application 11/082,002 6 Nevertheless, before an applicant can be put to this burdensome task, the examiner must provide sufficient evidence or scientific reasoning to establish the reasonableness of the Examiner’s belief that the functional limitation is an inherent characteristic of the prior art. The fact that a certain result or characteristic may occur or be present in the prior art is not sufficient to establish the inherency of that result or characteristic. In re Rijckaert, 9 F.3d 1531, 1534 (Fed. Cir. 1993). Weinstein discloses a fastener-driving tool 10 designed to drive fasteners, such as nails N, from a coiled strip S. Col. 3, ll. 20-24. The tool 10 includes a generally hollow housing structure 12 mounting a fastener- feeding mechanism 20 for feeding nails N into the tool 10. Col. 3, ll. 38-44. The tool includes a cylinder body 30 mounted within the housing structure 12. Col. 3, ll. 50-52. The tool 10 includes a nosepiece 50 mounted to the cylinder body 30 and to which the feeding mechanism 20 is mounted. Col. 4, ll. 1-4. The nosepiece functions for receiving a nail N from the feeding mechanism 20 and for guiding the nail N as it is driven by a driving blade 42. Col. 4, ll. 5-8. The fastener-feeding mechanism 20 includes a canister 200 having a fixed portion 202 fixed to the housing structure 12 and the nosepiece 50 and a pivotable portion 204 which may be pivoted to an open position for loading a coiled strip S into the canister 200. Col. 4, ll. 31-41. The fastener-feeding mechanism 20 includes a feeding claw 240 mounted to a piston pin 242 so as to be movable between withdrawn and advanced positions by a feeding piston 230. Col. 4, ll. 63-66. The feeding claw 240 has notched end fingers 246 adapted to engage one of the nails N of the strip S to advance the strip S when the feeding claw 240 is moved from the withdrawn position to the advanced position. Col. 5, ll. 8-14. The fastener- Appeal 2009-009157 Application 11/082,002 7 feeding mechanism 20 also includes a holding claw 250 which is biased in an engaging position as shown in Figs. 4 and 5 and a disengaging position as shown in Fig. 6. Col. 5, ll. 23-31. The holding claw 250 has distal end fingers 260 adapted to fit between two nails N of the strip S to engage the preceding nail N and to hold the engaged nail N so that the strip S including the engaged nail N does not move with the feeding claw 240 when the feeding piston 230 moves from the withdrawn position to the advanced position. Col. 5, ll. 31-39. We agree with Appellant that Weinstein’s spreader pawl or holding claw 250 does not function to “at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion” as recited in claim 14. The Examiner’s position that Weinstein is “clearly capable of resisting or partially inhibiting movement of one of the adjacent fasteners toward the nosepiece in a feed direction during the feed operation” (Ans. 3) is flawed because the above-quoted language of claim 14 is not a recitation of intended use that the reference only needs be capable of performing. Rather, the language is functional language and the Examiner has failed to provide sufficient evidence or scientific reasoning to establish the reasonableness of the belief that the functional limitation is an inherent characteristic of the prior art. Indeed, the Examiner has admitted in the Response to Arguments section of the Examiner’s Answer, that Weinstein’s fastener-driving tool 10 may not perform the same function or in the same manner as Appellant’s claimed invention. Accordingly, we are not convinced that there is a sufficient disclosure in Weinstein and evidence or scientific reasoning from the Examiner to support a finding that Weinstein inherently performs the recited function to anticipate claim 14. Appeal 2009-009157 Application 11/082,002 8 In view of the foregoing, we do not sustain the Examiner’s rejection of claims 14-16 and 18 under 35 U.S.C. § 102(b) as anticipated by Weinstein. Issue 2 Appellant contends that the spreader pawl or “holding claw 250 of Weinstein merely rides over the same fastener N that is engaged by the feed pawl 240 … [and] does not locate between a second pair of adjacent fasteners to resist movement of an engaged fastener of the second pair creating a second gap.” App. Br. 9. Appellant also contends that when the spreader pawl or holding claw 250 is in the position illustrated in Fig. 6 of Weinstein, the holding claw 250 is directly engaged with the same fastener as the feed pawl 240 so that the holding claw 250 cannot define a second gap between a second pair of adjacent fasteners during movement of the feed pawl 240 in the feed direction as required by claim 19. App. Br. 9-10. Appellant also contends that as shown in Figs. 4-6 of Weinstein, the gaps between all fasteners N never change during the sequence. 2nd Reply Br. 3. The Examiner’s position is that Weinstein anticipates claim 19 since the holding claw or spreader pawl 250 has a spreader tooth 260 “capable of locating a gap between a second pair of adjacent fasteners (see sequence of Figs[.] 4-6) and clearly capable of resisting movement of an engaged fastener in a feed direction during the feed operation and wherein the gap located by the spreader tooth is suitable to accept the width of the feed tooth (246).” 2nd Ans. 4. As with claim 14, the Examiner also posits that “[w]hile it is noted that the device of Weinstein may not perform the same function or in the same manner as [Appellant’s] invention, it is deemed that the claims are not restrictive to such device.” 2nd Ans. 5. Appeal 2009-009157 Application 11/082,002 9 Weinstein is discussed supra. We agree with Appellant that Weinstein does not meet claim 19’s functional language of the spreader pawl “resisting movement of an engaged fastener of the second pair in the feed direction during the feed motion and thereby defining a second gap between the second pair of adjacent fasteners, the second gap having a space suitable to accept the feed tooth width of the feed tooth therebetween.” The Examiner has failed to provide sufficient evidence or scientific reasoning to establish the reasonableness of the belief that the functional limitation is an inherent characteristic of the prior art. Again, the Examiner has admitted in the Response to Arguments section of the Examiner’s Answer that Weinstein’s fastener-driving tool may not perform the same function or in the same manner as Appellant’s claimed invention. As such, we are not convinced that there is a sufficient disclosure in Weinstein and evidence or scientific reasoning from the Examiner to support a finding that Weinstein inherently performs the recited function to anticipate claim 19. In view of the foregoing, we do not sustain the Examiner’s rejection of claims 19-21 and 23 under 35 U.S.C. § 102(b) as anticipated by Weinstein. CONCLUSIONS The Examiner erred in interpreting Weinstein to disclose a “spreader pawl . . . at least partially inhibiting movement of one of the subsequent fasteners toward the nosepiece during the feed motion” as recited in claim 14. The Examiner erred in interpreting Weinstein to disclose a “spreader pawl resisting movement of an engaged fastener of the second pair in the Appeal 2009-009157 Application 11/082,002 10 feed direction during the feed motion and thereby defining a second gap between the second pair of adjacent fasteners, the second gap having a space suitable to accept the feed tooth width of the feed tooth therebetween” as recited in claim 19. DECISION We reverse the Examiner’s decision to reject claims 14-16, 18-21, and 23 under 35 U.S.C. § 102(b) as anticipated by Weinstein. REVERSED Klh HARNESS, DICKEY & PIERCE, P.L.C. P.O.
