DECISION ON APPEAL STATEMENT OF THE CASE Marion Becella (Appellant) seeks our review under 35 U.S.C. § 134 of the final rejection of claims 1-20. We have jurisdiction under 35 U.S.C. § 6(b) (2002). Appeal 2009-006876 Application 10/472,840 2 SUMMARY OF DECISION We AFFIRM. THE INVENTION Appellant’s claimed invention is directed to a drive belt having a woven fabric traction layer (Spec. 1: 3-12). Claims 1, 19 and 20, reproduced below, are representative of the subject matter on appeal. 1. Drive belt having as a traction layer a woven fabric, which comprises exactly two layers of woven fabric, which are interlaced together, wherein the woven fabric contains weft threads and warp threads which are multifilaments, and wherein at least one of the woven fabric layers has a plain weave, a derived plain weave, a mixed plain weave or a satin weave. 19. A method of using a drive belt for driving a machine, the method comprising: providing a drive belt having as a traction layer a woven fabric, which comprises exactly two layers of woven fabric, which are interlaced together, wherein the woven fabric contains weft threads and warp threads which are multifilaments, and wherein at least one of the woven fabric layers has a plain weave, a derived plain weave, a mixed plain weave or a satin weave; bringing the drive belt in force-transmitting engagement with the machine to be driven; and, driving the drive belt. 20. A drive belt, comprising: a traction layer with exactly two layers of woven fabric being interlaced together, wherein the woven fabric contains weft threads and warp Appeal 2009-006876 Application 10/472,840 3 threads which are multifilaments, the traction layer being provided with a coating selected from the group consisting of rubber and a rubber-like thermoplastic material; wherein at least one of the woven fabric layers has a plain weave, a derived plain weave, a mixed plain weave or a satin weave. THE REJECTIONS The Examiner relies upon the following as evidence of unpatentability: Habegger US 4,767,389 Aug. 30, 1988 Tate US 4,821,780 Apr. 18, 1989 Appellant’s Admitted Prior Art in the Specification (Spec.1: 1-Spec. 2: 4) (hereinafter referred to as the “Instant Specification”1) The following rejections2 by the Examiner are before us for review: 1. Claims 1-6, 8-13, 19 and 20 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Tate in view of the Instant Specification. 2. Claims 7 and 14-18 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Tate in view of the Instant Specification, and further in view of Habegger. 1 Both Appellant (App. Br. 3, 7) and the Examiner (Ans. 3) refer to the portion of Appellant’s Specification deemed by the Examiner to be admitted prior art as the “Instant Specification.” We will do the same in this appeal. 2 The rejection of claims 1, 3, 19 and 20 under 35 U.S.C. § 102(b) as being anticipated by Tate, as set forth in the Final Rejection mailed December 11, 2007 (Final Rejection 2), has been withdrawn and is, therefore, not part of this appeal (Ans. 3). Appeal 2009-006876 Application 10/472,840 4 ISSUES The issues before us are: (1) whether the Examiner erred in finding that Tate’s woven fabric wire is a drive belt as recited in claims 1, 19 and 20 (App. Br. 5); (2) whether the Examiner erred in concluding that the combined teachings of Tate and the Instant Specification would have led a person having ordinary skill in the art to a woven fabric drive belt comprising threads which are multifilaments as called for in claim 1 (App. Br. 7); and (3) whether the Examiner erred in concluding that the combined teachings of Tate and the Instant Specification would have led a person having ordinary skill in the art to a woven fabric drive belt having a rubber coated traction layer as called for in claim 20 (App. Br. 6, 9). FINDINGS OF FACT We find that the following enumerated findings are supported by at least a preponderance of the evidence. Ethicon, Inc. v. Quigg, 849 F.2d 1422, 1427 (Fed. Cir. 1988) (explaining the general evidentiary standard for proceedings before the Office). Appellant’s Specification 1. Appellant’s Specification describes in the background of the invention that: [t]he term “belt” is used herein as a collective term for drive belts, conveyor belts and process belts. The traction layer of a belt, especially of a drive belt, frequently consists . . . of a woven fabric. This traction layer is rubber coated. . . . . Appeal 2009-006876 Application 10/472,840 5 The woven fabric can be produced from all known types of yarn, such as for example multifilaments, monofilaments . . . (Spec. 1: 2-13 and Spec. 2: 1-3). 2. One of Appellant’s objects is to provide a drive belt that permits a large transmission of force and remains flexible (Spec. 2: 23-28). The Examiner’s Findings 3. The Examiner finds that Tate describes a papermaker’s fabric wire used to convey the paper making materials through the process (Ans. 4). 4. The Examiner finds that “[p]apermaker’s fabrics are known to be used in endless belt form and travel around rollers.” (Ans. 4). 5. The Examiner finds that “[a] papermaker’s fabric could be broadly considered a ‘drive belt’ as recited, as the fabric does transmit driving motion from a driving roller to a non-driven roller.” (Ans. 4). 6. The Examiner finds that: [t]he papermaker’s fabric in Tate is used as a belt to both convey and as a process belt in the papermaking process. Also rollers around which the fabric is wrapped drive the belt. The papermaker’s fabric disclosed is clearly a “drive belt” by both appellant’s own definition and the broadest reasonable interpretation of the term “drive belt.” (Ans. 6-7). 7. The Examiner finds that Tate describes essentially all of the limitations called for in the claims; except that Tate does not describe the use of multifilaments (Ans. 5). Appeal 2009-006876 Application 10/472,840 6 8. The Examiner finds that Appellant’s Instant Specification “in the discussion of the background of the invention, clearly teaches the widely known and practiced use of all types of yarns monofilament and multifilament in woven belt fabrics.” 3 (Ans. 5). 9. The Examiner finds in regards to claim 20 that (a) the portion of the fabric that contacts the rollers is considered the claimed traction layer (Ans. 4), and (b) the coating layer called for in the claim is admitted as prior art by Appellant (Ans. 5). The Board’s Findings 10. Tate describes a multi-layer fabric for papermaking having at least two layers formed by interweaving warp and wefts with each other, wherein the uppermost layer is adapted to support a paper slurry thereon (col. 3, ll. 1-23). 11. Tate further describes that the multi-layer fabric has mesh openings for even drainage, wherein the lower-most layer may be rigidly woven to maintain the runnability of the fabric and wear resistance (col. 5, l. 21-col. 6, l. 3). 12. A person having ordinary skill in the art would understand that a conveyor belt usually comprises a belt as a continuous loop of material that is rotatable about at least two rollers or rolling shafts, 3 Kositzke (U.S. Patent No. 4,909,284, issued Mar. 20, 1990), referred to by Appellant (App. Br. 8) and the Examiner (Ans. 7), further supports the Examiner’s finding that it is old and well known in the papermaking art to have a wire made from multilayered fabric, wherein the weave selected for the wire may be a two layer weave of synthetic yarns such as multifilament or monofilament yarns (col. 2, ll. 33-35) and the wire is in the form of an endless belt 30 (fig. 4). Appeal 2009-006876 Application 10/472,840 7 wherein one of the rollers or rolling shafts is powered and at least one of the other rollers or rolling shafts is non-powered. 13. A person having ordinary skill in the art would understand that a belt in a conveyor belt is a drive belt since the belt is capable of transferring power from a powered roller or rolling shaft to a non- powered roller or rolling shaft, wherein the non-powered roller or rolling shaft is a machine or machine part. 14. A person having ordinary skill in the art would understand that the lower-most portion of a belt that contacts rollers or rolling shafts is a traction layer, and that rubber or a rubber coating would improve traction between the rollers and the belt. 15. The ordinary meaning of the word “drive” includes “the means for giving motion to a machine or a machine part.” MERRIAM- WEBSTER’S COLLEGIATE DICTIONARY (10th ed. 1999). 16. The ordinary meaning of the word “belt” includes “a continuous band of tough flexible material for transmitting motion and power or conveying materials.” MERRIAM-WEBSTER’S COLLEGIATE DICTIONARY (10th ed. 1999). 17. Additional findings as necessary appear in the Analysis portion of this opinion. PRINCIPLES OF LAW Obviousness “Section 103 forbids issuance of a patent when ‘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 Appeal 2009-006876 Application 10/472,840 8 invention was made to a person having ordinary skill in the art to which said subject matter pertains.’” KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including (1) the scope and content of the prior art, (2) any differences between the claimed subject matter and the prior art, (3) the level of skill in the art, and (4) where in evidence, so-called secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17-18 (1966). See also KSR, 550 U.S. at 407 (“While the sequence of these questions might be reordered in any particular case, the [Graham] factors continue to define the inquiry that controls.”). In KSR, the Supreme Court stated that “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” Id. at 416 (citing United States v. Adams, 383 U.S. 39, 50-51 (1966)). In KSR, the Supreme Court held that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. In KSR, the Supreme Court stated that: Often, it will be necessary for a court to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge possessed by a person having ordinary skill in the art, all in order to determine whether there was an apparent reason to Appeal 2009-006876 Application 10/472,840 9 combine the known elements in the fashion claimed by the patent at issue. Id. at 418. The Court noted that “[t]o facilitate review, this analysis should be made explicit.” Id. (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”)). However, “the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR, 550 U.S. at 418. Claim Construction When construing claim terminology in the United States Patent and Trademark Office, claims are to be given their broadest reasonable interpretation consistent with the specification, reading claim language in light of the specification as it would be interpreted by one of ordinary skill in the art. In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004). ANALYSIS Rejection of claims 1-6, 8-13, 19 and 20 under 35 U.S.C. § 103(a) as being unpatentable over Tate in view of the Instant Specification Appellant argues claims 1-6 and 8-13 as a group (App. Br. 7). As such, we select claim 1 as representative of the group, and claims 2-6 and 8- 13 will stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(vii) (2007). Appellant argues claim 19 and 20 separately (App. Br. 6-8). Appeal 2009-006876 Application 10/472,840 10 Claims 1-6 and 8-13 Appellant contends that (1) Tate’s papermaker’s fabric is not a drive belt as called for in claim 1, as a drive belt is used to enable power transmission from a source to a machine (App. Br. 5); and (2) a person having ordinary skill would never use Tate’s papermaker’s fabric as a drive belt to transmit power (App. Br. 5). The Examiner found that (1) Tate’s papermaker fabric wire is used to convey paper making materials (Fact 3, see also Fact 10); (2) “[p]apermaker’s fabrics are known to be used in endless belt form and travel around rollers” (Fact 4); and (3) that “[a] papermaker’s fabric could be broadly considered a ‘drive belt’ as recited, as the fabric does transmit driving motion from a driving roller to a non-driven roller.” (Facts 5-6). Initially, we will construe the meaning of the claim term “drive belt.” The ordinary meaning of the word “drive” includes “the means for giving motion to a machine or a machine part.” (Fact 15). The ordinary meaning of the word “belt” includes “a continuous band of tough flexible material for transmitting motion and power or conveying materials.” (Fact 16). Appellant’s object of providing a drive belt that permits a large transmission of force and remains flexible (Fact 2), is consistent with this ordinary meaning. A person having ordinary skill in the art would understand the phrase “drive belt,” as called for in independent claim 1 in light of the ordinary meanings of the words used in the phrase, to refer to a continuous band of material for transmitting motion and power to a machine or machine part. See In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004) Appeal 2009-006876 Application 10/472,840 11 (When construing claim terminology in the United States Patent and Trademark Office, claims are to be given their broadest reasonable interpretation consistent with the specification, reading claim language in light of the specification as it would be interpreted by one of ordinary skill in the art.). Appellant has not contested the Examiner’s finding that Tate’s papermaker’s fabric is in the form of a conveyor belt (see Fact 4)4. A person having ordinary skill in the art would understand (1) that a conveyor belt usually comprises a belt as a continuous loop of material that is rotatable about at least two rollers or rolling shafts, wherein one of the rollers or rolling shafts is powered and at least one of the other rollers or rolling shafts is non-powered (Fact 12), and that a belt in a conveyor belt is a drive belt since the belt is capable of transfering power from the powered roller or rolling shaft to the non-powered roller or rolling shaft, wherein the non-powered roller or rolling shaft is a machine or machine part (Fact 13). Therefore, we find that Tate describes a drive belt as recited in claim 1. Appellant further contends that the fact that Appellant’s Specification states in the background that multifilaments have been used for woven fabrics in a traction layer of drive belts does not make it obvious to use them in a papermaker’s fabric. (App. Br. 7). The Examiner found that, while Tate describes the use of monofilaments and not multifilaments as called for in claim 1 in a papermaker’s fabric (Fact 7), the Instant Specification describes the use of 4 See also Footnote 3. Appeal 2009-006876 Application 10/472,840 12 monofilaments or multifilaments in woven belt fabrics. (Fact 8, see also Fact 1). Tate describes a woven fabric drive belt formed from monofilament yarns (Fact 10). Appellant’s Specification describes that woven fabric in belts could be produced by monofilament or multifilament yarns. (Fact 1). This description implies that a multifilament yarn could have been simply substituted for a monofilament yarn when making a drive belt. We conclude that it would have been obvious to a person having ordinary skill in the art to combine the teachings of Tate and the Instant Specification by substituting for Tate’s monofilament yarns the multifilament yarns as taught by the Instant Specification (Fact 1). The Appellant provides no reason why such a substitution would have been beyond the level of ordinary skill in the art or why the substitution might have done more than yield a predictable result. See KSR, 550 U.S. at 416 (holding that “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.”). Therefore, we conclude that Appellant has not demonstrated that the Examiner erred in rejecting claim 1 over Tate in view the Instant Specification. Appellant has likewise not demonstrated error in the Examiner’s rejection of claims 2-6 and 8-13, which stand or fall with claim 1. Appeal 2009-006876 Application 10/472,840 13 Claim 19 Appellant contends that Tate does not describe a drive belt as called for by the steps of claim 19 (App. Br. 6). The Examiner found that Tate describes a drive belt (Facts 3-6). For the same reasons we previously found regarding claim 1, supra, we find that Tate describes a drive belt. Therefore, for the same reasons we previously found regarding claim 1, supra, we conclude that Appellant has not demonstrated that the Examiner erred in rejecting claim 19 over Tate in view the Instant Specification. Claim 20 Appellant contends that Tate does not describe a drive belt or provide a traction layer with a coating selected from the group consisting of rubber and a rubber-like thermoplastic material as called for in claim 20 (App. Br. 6). Appellant further contends that since the water draining function is essential for Tate’s papermaker’s fabric, coating Tate’s papermaker’s fabric with rubber or a rubber-like thermoplastic material would destroy the fabric’s water shedding functionality (App. Br. 9). The Examiner found that Tate describes a drive belt (Facts 3-6). The Examiner further found that (1) the coating layer called for in claim 20 is admitted as prior art by Appellant, and (2) the portion of the fabric that contacts the rollers is considered the claimed traction layer (Fact 9). For the same reasons we previously found regarding claim 1, supra, we find that Tate describes a drive belt. A person having ordinary skill in the art would understand that the portion of a belt that contacts rollers or rolling shafts is a traction layer, and Appeal 2009-006876 Application 10/472,840 14 that rubber or a rubber coating would provide considerable traction between the rollers and the belt (Fact 14). Tate describes that the multi-layer fabric has mesh openings for even drainage (Fact 11). We find that when Tate’s woven fabric belt is provided with a rubber coating, only the yarns, not the mesh spaces between the yarns, need be coated. Further, we find that to provide considerable traction between Tate’s woven fabric belt and the rollers, only the part of the yarns that contact the rollers need be coated. Therefore, we find that Tate’s woven fabric driven belt when coated with rubber could still maintain its mesh openings for drainage (see Facts 10-11). We conclude that it would have been obvious to a person having ordinary skill in the art to combine the teachings of Tate and the Instant Specification by providing Tate’s yarns with a coating of rubber where the yarns contact the rollers as taught by the Instant Specification. (See Fact 1). We find that providing Tate’s yarns with a coating of rubber only where the yarns contact the rollers could have been reasonably predicted to yield the result of improving traction between the rollers and the yarn of the belt. No reason is apparent why providing such a coating would have been beyond the level of ordinary skill in the art. See KSR, 550 U.S. at 417 (holding that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.”). Appeal 2009-006876 Application 10/472,840 15 Therefore, we conclude that Appellant has not demonstrated that the Examiner erred in rejecting claim 1 over Tate in view the Instant Specification. Rejection of claims 7 and 14-18 under 35 U.S.C. § 103(a) as being unpatentable over Tate in view of the Instant Specification, and further in view of Habegger In contesting the rejection of claims 7 and 14-18, Appellant simply relies on the contentions made with respect to the rejection of claim 1 (App. Br. 9). We previously found that Appellant’s contentions regarding the rejection of claim 1 are not persuasive. Therefore, we conclude that Appellant has not demonstrated that the Examiner erred in rejecting claims 7 and 14-18 over Tate in view of the Instant Specification, and further in view of Habegger. CONCLUSIONS Appellant has not established that the Examiner erred in finding that Tate’s woven fabric wire is a drive belt as recited in claims 1, 19 and 20. Appellant has not established that the Examiner erred in concluding that the combined teachings of Tate and the Instant Specification would have led a person having ordinary skill in the art to a woven fabric drive belt comprising threads which are multifilaments as called for in claim 1. Appellant has not established that the Examiner erred in concluding that the combined teachings of Tate and the Instant Specification would have led a person having ordinary skill in the art to a woven fabric drive belt having a rubber coated traction layer as called for in claim 20. Appeal 2009-006876 Application 10/472,840 16 DECISION The decision of the Examiner to reject claims 1-20 is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv) (2007).
