SCHOPFER, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving apparatus and method claims related to jaw-type surgical instruments and inserts therefor. The Examiner rejected the claims as obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm-in-part. 1 According to Appellants, the real party in interest is Vitalitec International, Inc. App. Br. 2. Appeal 2012-005726 Application 10/664,273 2 STATEMENT OF THE CASE Background The present application describes a jaw-type surgical instrument including an insert for engaging body tissue with increased traction. Spec. ¶ 0001. The Claims Claims 1–3, 5–19,2 23–49, and 51–54 are on appeal. Independent claim 1 is representative and reads as follows. 1. An insert for attachment to a jaw-type surgical instrument adapted for grasping or occluding a vessel, said insert comprising an elongate member having opposed proximal and distal ends, a compliant cushion having a tissue- engaging contact surface and having a plurality of molded, hooked traction elements on at least a region of said surface, wherein said hooked traction elements are of unitary construction with said tissue engaging contact surface, said insert further comprising a back surface opposite to said contact surface, and a jaw attachment member on the back surface, wherein said contact surface and said back surface extend between said opposed proximal and distal ends and face opposite directions. App. Br. 18 (Claims App’x). 2 Although the Examiner and Appellants indicate that claims 20 and 21 also stand rejected (Ans. 3, App. Br. 4), none of the rejections in the Office Action mailed Apr. 26, 2011 or in the Answer includes claim 20 or claim 21. Therefore, these claims are not subject to any outstanding rejection. Appeal 2012-005726 Application 10/664,273 3 The Rejections 1. The Examiner maintains that claims 1–3, 15–19, 30–33, 48, 49, and 51–53 are unpatentable under 35 U.S.C. § 103(a) over Fogarty3 in view of Pierce.4 2. The Examiner maintains that claims 5–7, 23–25, and 42–47 are unpatentable under 35 U.S.C. § 103(a) over Fogarty and Pierce in view of Bramstedt.5 3. The Examiner maintains that claims 8–14, 26–29, and 34–41 are unpatentable under 35 U.S.C. § 103(a) over Fogarty, Pierce, and Bramstedt in view of Romanko.6 4. The Examiner maintains that claim 54 is unpatentable under 35 U.S.C. § 103(a) over the combination of Fogarty and Pierce in view of Romanko. DISCUSSION 1. Fogarty in view of Pierce Appellants argue for reversal of this rejection on the basis of the limitations in three groups of claims: (a) independent claims 1, 19, 30, 32, 48, and 497; (b) dependent claim 3; and (c) dependent claims 52 and 53. See App. Br. 13–15. We address these groups separately below. (a) Claims 1, 19, 30, 32, 48, and 49. 3 Fogarty et al., US 6,228,104 B1, issued May 8, 2001. 4 Pierce, US 5,893,878, issued Apr. 13, 1999. 5 Bramstedt, US 2,706,987, issued Apr. 26, 1955. 6 Romanko et al., US 6,484,371 B1, issued Nov. 26, 2002. 7 Pursuant to 37 C.F.R. § 41.37(c)(1)(vii)(2008), this ground of rejection, as it applies to this group of claims, is decided on the basis of claim 1. Appeal 2012-005726 Application 10/664,273 4 According to the Examiner, Fogarty teaches an insert for attachment to a jaw-type surgical instrument as required by claim 1, except that Fogarty does not include hooked traction elements on the insert. Ans. 5. With respect to the hooked traction elements, the Examiner relies on Pierce. The Examiner finds that Pierce teaches a jaw-type instrument with a surface having a plurality of molded, hooked traction elements (24 and 80 together in Figure 13) of unitary construction with the tissue engaging surface of the device. Id. The Examiner concludes that it would have been obvious “to have hooked elements as this aids in securely holding tissue.” Id. Appellants raise two issues with respect to this ground of rejection as it applies to claim 1. First, Appellants argue that the structures 24 and 80 in Pierce are not hooks as called for in the claims. App. Br. 13. Second, Appellants argue that the devices taught by Fogarty and Pierce are “sufficiently different” such that a person of ordinary skill in the art would not consider combining them and would not expect there to be interchangeable features between them. Id. at 13–14. Findings of Fact The following findings of fact (“FF”) are supported by a preponderance of the evidence of record. 1. Fogarty discloses a surgical clamp comprising: a pair of elongate jaws connected together for movement toward each other, at least one of the jaws having an outer surface in opposition to the other jaw. An elongate cavity extends longitudinally within the jaw. The cavity is adapted for slidably receiving a clamp pad. An elongate channel opens through the outer surface and longitudinally connects the cavity to the outer surface. The channel is generally commensurate with the cavity longitudinally.

Cir. y r Appeal 2012-005726 Application 10/664,273 7 2011) (citation omitted). During prosecution, an application’s claims are given their broadest reasonable scope consistent with the specification. In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004). The words used in a claim must be read in light of the specification, as it would be interpreted by one of ordinary skill in the art. Id. Further, The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. In re Keller, 642 F.2d 413, 425 (CCPA 1981) (citations omitted). Similarly, the Federal Circuit has stated: It is well-established that a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements. In re Etter, 756 F.2d 852, 859 (Fed. Cir. 1985) (en banc) (“Etter’s assertions that Azure cannot be incorporated in Ambrosio are basically irrelevant, the criterion being not whether the references could be physically combined but whether the claimed inventions are rendered obvious by the teachings of the prior art as a whole.”); In re Sneed, 710 F.2d 1544, 1550 (Fed. Cir. 1983) (“[I]t is not necessary that the inventions of the references be physically combinable to render obvious the invention under review.”); In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . .”). In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012). Analysis Appellants do not dispute that Fogarty discloses every limitation of claim 1 other than the requirement that the tissue-engaging surface includes Appeal 2012-005726 Application 10/664,273 8 a plurality of molded, hooked traction elements. See Ans. 5; App. Br. 13– 14; FF 1. Pierce discloses “[a]n apparatus for surgically manipulating tissue without causing irreparable damage to the tissue during retention and manipulation.” FF 2. Pierce describes a tissue manipulator 10 with a contact member 18 attached near its distal end with a plurality of projections 24 on the contact member. FF 3. Pierce states that the contact member includes “a plurality of serrations, teeth, stipples, barbs, hooks or other type projections[.]” FF 4. Pierce also discloses that the “projections are preferably configured to point in the desired direction of traction or retrograde of the tissue.” FF 5. Further, Pierce describes an embodiment in Figure 13 that is the result of one method of constructing the pointed projections on its device, resulting in a plurality of second lower profile projections 80 beneath the pointed projections 24. FF 6. Appellants first argue that the structures 24 and 80 in Pierce are not hooks as called for in the claims. App. Br. 13. Rather, Appellants assert, “24 is a point of material which is raised up out of the base material, leaving the underlying depression 80 as shown.” Id. (citing Pierce, col. 6, ll. 3–19). Appellants contend that these structures are not hooks because “[t]here is a structural difference between a projection and a hook.” Id. We find this argument unpersuasive. Pierce expressly states that the projections on the contact member may be hooks. FF 4. Further, the Examiner defines a hook as “a curved substance for catching, pulling, holding or suspending something.” Ans. 5. We find that the Examiner’s definition of hook is consistent with the ordinary meaning of the term (see, e.g., FF 8), and we find that the Examiner’s interpretation of hooked traction elements is consistent with the Appeal 2012-005726 Application 10/664,273 9 broadest reasonable interpretation of the claims in light of the Specification. We conclude that under the definition of hook provided by the Examiner, the portions of the device of Pierce including projections 24 and 80, as shown in Figure 13, are hooked traction elements as required by the claims because together they constitute a curved portion for catching and holding tissue. Appellants also argue that the devices taught by Pierce and Fogarty are sufficiently different that a skilled artisan “would not consider combining them.” App. Br. 13. Appellants state that “Fogarty already discloses a textured surface . . . and there is no need to look for a hook structure . . . for incorporation into [the device of] Fogarty.” Id. at 13–14. Further, Appellants argue that it is not clear how the injection molded surface of Fogarty would be substituted for the gouged surface disclosed in Pierce and there is no suggestion in either reference to make this substitution. Id. at 14. Finally, Appellants assert that “a person skilled in the art would not expect interchangeable features between [the devices of Fogarty and Pierce].” Id. We find that this argument by Appellants is also unpersuasive. First, we agree with the Examiner that both Fogarty and Pierce “describe surgical instruments with jaws for retaining tissue.” Ans. 9. Thus, we find that they are not so different that one of ordinary skill in the art would not consider combining them. We also agree with the Examiner that Pierce provides sufficient teaching to suggest that it would have been obvious to combine Fogarty and Pierce to include hooked elements that cause minimal trauma and aid in securely holding tissue. See Ans. 5. As noted, Pierce discloses that the contact member of the device includes hooks that “minimally puncture the tissue surface” and are “configured to point in the desired Appeal 2012-005726 Application 10/664,273 10 direction of traction.” FF 4; FF 5. Pierce also discloses that the device is designed to provide “substantial holding power over the contact surface with less reliance on pressure induced friction” where the incisions made by the device are “of insufficient size to [affect] the structural integrity of the organ.” FF 7. Finally, we note that, contrary to the assertions made by Appellants, “a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.” In re Mouttet, 686 F.3d at 1332 (citations omitted). We conclude that the teachings of Fogarty and Pierce are sufficient to suggest to one of ordinary skill in the art the combination proposed by the Examiner. See In re Keller, 642 F.2d at 425. Based on the foregoing, we find that the Examiner has established a prima facie case of obviousness with respect to claims 1, 19, 30, 32, 48, and 49, which Appellants have failed to rebut. Accordingly, we affirm this rejection with respect to this group of claims. Claims 2, 1518, 31, 33, and 51 fall with their respective independent claim. 37 C.F.R. § 41.37(c)(1)(vii). (b) Claim 3 Claim 3 requires that the molded, hooked traction elements of claim 1 be “configured to have at least one crook.” With respect to claim 3, the Examiner finds that the hooked traction elements in the device of Pierce include two crooks, elements 24 and 80 in Figure 13. Ans. 5. Appellants argue that elements 24 and 80 in Pierce are separate structures and cannot be considered one hook with two crooks. App. Br. 14–15. As noted above, the Examiner defines a hook as “a curved substance for catching, pulling, holding or suspending something.” Ans. 5. Further, Appeal 2012-005726 Application 10/664,273 11 with respect to claim 3, the Examiner defines the word crook as “a curved or hooked thing” according to the World English Dictionary. Id. at 9. The Examiner then defines the hook of Pierce as elements 24 and 80 together, which have two curved areas, or crooks, as shown in Figure 13. Id.; FF 6. As an initial matter, we find that the Examiner’s definition of “crook” is consistent with the ordinary meaning of the term. See, e.g., FF 9. Under the definitions of hook and crook provided by the Examiner, we find that each hooked traction element in Figure 13 of Pierce includes two curved portions, which may reasonably be described as crooks, as required by the claim. See FF 6. Appellants assert that elements 24 and 80 are separate structures that cannot be considered together to form a hooked traction element because these elements independently extend from the surface of the device of Pierce. Reply Br. 2–3. While elements 24 and 80 may be considered as two hooks, as suggested by Appellants, we disagree with the conclusion that they cannot also be defined together as a hooked traction element as required by the claims, particularly because they are formed as a pair in the construction process. See FF 6. Further, Appellants have not pointed to any portion of the record before us that would preclude this interpretation. Based on the foregoing, we find that the Examiner has established a prima facie case of obviousness with respect to claim 3, which Appellants have failed to rebut. Accordingly, we affirm the rejection of claim 3. (c) Claims 52 and 53. Regarding claims 52 and 53, the Examiner asserts that Fogarty and Pierce teach the claimed invention other than the requirement that the device have two separate overmolds that connect the jaw attachment member to the App App cush more conc sepa vario v.

(quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Analysis Claim 52 requires that the insert of claim 1 includes four elements: a first overmold, a second overmold, a compliant cushion, and a jaw attachment member. Figure 9A depicts such an arrangement of elements including first overmold 510 and second overmold 508. FF 10. Fogarty discloses an insert having a neck 96 that connects a draw cord 86 to a pad body 98. FF 11. Fogarty also discloses that the pad body is made of an elastomer having a shore durometer between 15A and 70A and that the neck 96 may be made of a different material than the pad body, such as plastic. FF 12; FF 13. We find that the Examiner, on this record, fails to establish why one of ordinary skill in the art would have modified the structure of Fogarty as shown in Figure 4 to include the arrangement of separate elements required by claim 52, including a first overmold with the required rigidity, a second overmold with the required rigidity and lower rigidity than the first overmold, a compliant cushion, and a jaw attachment member. The Examiner acknowledges that Fogarty does not disclose separate pieces connecting the jaw attachment member to the cushion. Ans. 6. However, the Examiner asserts that “constructing a formerly integral structure in various elements involves only routine [skill] in the art.” Id. We disagree that this principle alone is sufficient to reject the claims as obvious, and the Examiner provides no reason why a person of ordinary skill in the art would have found it obvious make such a change in Fogarty. Appeal 2012-005726 Application 10/664,273 15 The Examiner also asserts that it would have been obvious to use a more rigid material, such as plastic, for the first overmold in order “to maintain the position of the cushion in the jaws.” Ans. 6. While Fogarty does disclose that the neck 96 may be made of plastic (FF 13), the Examiner does not explain how the use of plastic in the neck of Fogarty would lead a person of ordinary skill in the art to modify Fogarty to meet the arrangement of elements required by these claims. Accordingly, we conclude that the Examiner has not provided an apparent reason to modify the structure of Fogarty to meet the claim requirements. Based on the foregoing, we find that the Examiner has not established a prima facie case of obviousness, and thus, we reverse the rejection of claims 52 and 53. 2. Fogarty and Pierce in view of Bramstedt Regarding the limitations added by dependent claims 5–7, 23–25, and 42–47, the Examiner acknowledges that Fogarty and Pierce are silent regarding the height of the traction elements. Ans. 7. The Examiner relies on Bramstedt for these limitations, stating that Bramstedt teaches surgical clamp inserts with elements that are 0.004–0.008 inches high “in order to provide lessened or reduced residual witness marks corresponding to less trauma to the clamped vessel.” Id. (citing Bramstedt, col. 1, l. 35). The Examiner concludes that it would have been obvious to modify the device of Fogarty and Pierce to include traction elements that are no more than 0.3 mm high “in order to provide lessened or reduced residual witness marks corresponding to less trauma to the clamped vessel.” Id. The sole issue presented with respect to this rejection is whether the evidence of record supports the Examiner’s conclusion that it would have Appeal 2012-005726 Application 10/664,273 16 been obvious to one of ordinary skill in the art to modify the device of Fogarty and Pierce based on the teachings of Bramstedt. Findings of Fact 14. Bramstedt discloses “an insert member for surgical needle clamps,” designed to “securely hold a surgical needle against slipping.” Bramstedt col. 1, ll. 15–16 and 37–38. 15. Bramstedt discloses that the “needle clamp jaw insert” has “pyramidal teeth and made from a material having a Rockwell hardness of between 53 and 70 with the angle of inclination of the sides of the pyramid forming each tooth being between 40 and 45 deg. and the height of each tooth being between .004 and .008 inch.” Bramstedt col. 1, ll. 30–35. 16. Bramstedt teaches that “the design and hardness of the teeth of these insert members determines their gripping power and durability.” Bramstedt col. 1, l. 77–col. 2, l. 1. Principles of Law Establishing a prima facie case of obviousness of an invention comprising a combination of known elements requires “an apparent reason to combine the known elements in the fashion claimed . . . .” KSR, 550 U.S. at 418. “[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.” Id. (quoting In re Kahn, 441 F.3d at 988). Analysis In making this rejection the Examiner asserts that Bramstedt discloses traction elements that are 0.004–0.008 inches in height “in order to provide Appeal 2012-005726 Application 10/664,273 17 lessened or reduced residual witness marks corresponding to less trauma to the clamped vessel.” Ans. 7. The Examiner concludes that one of ordinary skill in the art would modify the device of Fogarty and Pierce to include traction elements of similar height for the same reason. Id. The Examiner also argues that Bramstedt is in the same field of endeavor as the present application and is directed to clamping and holding tissue, as are Fogarty and Pierce. Id. at 10. Bramstedt discloses “an insert member for surgical needle clamps.” FF 14. Bramstedt does disclose that teeth of the insert are between 0.004– 0.008 inches tall and that the design and hardness of the teeth determine their gripping power and durability. FF 15; FF 16. However, contrary to the Examiner’s assertions, we find that Bramstedt is not “directed to clamping and holding tissue” and does not disclose that the height of the teeth on the disclosed clamp insert is designed “to provide lessened or reduced residual witness marks corresponding to less trauma in the clamped vessel.” See Ans. 7, 10. Rather, Bramstedt’s insert member is designed to “securely hold a surgical needle against slipping.” FF 14. Thus, we find that the Examiner mischaracterizes the disclosures in Bramstedt. Beyond these mischaracterizations, the Examiner bases this rejection only on the fact that Bramstedt discloses teeth with a height of 0.004–0.008 inches and that the design and hardness of the teeth determines their gripping power and durability. See Ans. 7, 10; FF 15; FF 16. We find that these disclosures are not sufficient to support the Examiner’s rejection because there is no apparent reason to employ the tooth height of Bramstedt in the tissue clamping device of Fogarty and Pierce, given that Fogarty and Pierce are concerned with clamping or manipulating tissue without Appeal 2012-005726 Application 10/664,273 18 damaging the tissue, whereas Bramstedt is concerned with providing an insert with sufficient gripping power and durability for clamping a surgical needle. Based on the foregoing, we conclude that the Examiner has not established that one of ordinary skill in the art would have had an apparent reason to combine Fogarty and Pierce with Bramstedt to create the claimed device, and thus, the Examiner has not established a prima facie case of obviousness. Accordingly, we reverse this rejection. 3. Fogarty, Pierce, and Bramstedt in view of Romanko We find that the Examiner erred in rejecting claims 8–14, 26–29, and 34–41 for the same reasons articulated with respect to the preceding rejection. The Examiner has not identified anything in Romanko that would rectify the Examiner’s error in combining Fogarty and Pierce with Bramstedt. Accordingly, we reverse this rejection. 4. Fogarty and Pierce in view of Romanko With respect to claim 54, the Examiner acknowledges that Fogarty and Pierce do not disclose a hook with a single stem and two crooks extending in opposite directions. Ans. 8. The Examiner asserts that Romanko teaches a hook with this configuration, and the Examiner argues that replacing the hook of Pierce with the hook of Romanko is an obvious substitution of one known element for another and would be expected to yield a device that hooks tissue. Id. The issue presented with respect to this rejection is whether the Examiner erred in considering Romanko as analogous art. Appeal 2012-005726 Application 10/664,273 19 Findings of Fact 17. Romanko is concerned with providing: a new class of fasteners which have reduced notch sensitivity, especially in the lateral direction, and which are lightweight, strong, thin, and flexible (e.g., have a low normalized flex modulus or degree of stiffness), and whose holding power is comparable to or greater than the holding power of conventional hook and loop type fasteners. Romanko col. 4, ll. 32–38. 18. Romanko discloses “a mechanical fastener, such as a hook and loop type fastener, which is uniaxially oriented in the longitudinal direction.” Romanko col. 4, ll. 39–41. 19. Romanko discloses that uniaxial orientation in the longitudinal direction provides “improved tensile strength and reduced flex modulus in the longitudinal direction . . . and improved notch sensitivity in the lateral direction.” Romanko col. 4, ll. 44–47. 20. Romanko teaches that “[b]ecause of these properties, the fasteners of the present invention are uniquely suited to provide improved performance in applications such as bundling.” Romanko col. 4, ll. 48–50. 21. The present application is concerned with “atraumatic, jaw-type surgical instruments” having inserts with “an engaging surface that provides increased traction on body tissues.” Spec. ¶ 0001. 22. The Specification states that “there remains a need for jaw-type surgical instruments with atraumatic inserts having improved grasping capabilities, including atraumatic inserts that can Appeal 2012-005726 Application 10/664,273 20 approach or match the gripping and traction supplied by conventional steel jawed instruments.” Spec. ¶ 0010. Principles of Law To rely upon a reference as a basis for an obviousness rejection of Appellants’ claims, the reference must either (1) be in the field of Appellants’ endeavor or (2) be reasonably pertinent to the particular problem with which the inventor was concerned. In re Kahn, 441 F.3d 977, 986–87 (Fed. Cir. 2006) (citing In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992)). Analysis To support this rejection, the Examiner argues that the hooks in Romanko are analogous to the hooks in Pierce and it would have been obvious to modify the hooks in Pierce with the shape of the hooks in Romanko to aid in capturing different types of tissue. Ans. 10. We disagree with the Examiner’s unsupported conclusion for the reasons that follow. Romanko discloses “a mechanical fastener, such as a hook and loop type fastener, which is uniaxially oriented in the longitudinal direction[,]” which provide “improved tensile strength and reduced flex modulus in the longitudinal direction . . . and improved notch sensitivity in the lateral direction.” FF 18; FF 19. Because of these properties, Romanko discloses that the hook and loop fasteners “are uniquely suited to provide improved performance in applications such as bundling.” FF 20. Based on these disclosures, we agree with Appellants that Romanko deals with hook and loop fasteners and not tissue clamping structures. See App. Br. 16. Thus, we find that Romanko is not in the same field of endeavor as the present application. Appeal 2012-005726 Application 10/664,273 21 Next, we consider whether Romanko is reasonably pertinent to the particular problem with which the present application is concerned. Romanko is concerned with providing fasteners with improved properties having holding power comparable to or greater than traditional hook and loop fasteners. FF 17. The present application is concerned with “atraumatic, jaw-type surgical instruments” having inserts with “an engaging surface that provides increased traction on body tissues.” FF 21. The Specification further states that “there remains a need for jaw-type surgical instruments with atraumatic inserts having improved grasping capabilities, including atraumatic inserts that can approach or match the gripping and traction supplied by conventional steel jawed instruments.” FF 22. We find no connection between the problems addressed by Romanko and the need for improved atraumatic inserts expressed in the Specification, and we note that the Examiner does not provide any support in concluding that the hooks of Romanko and Pierce are analogous. Thus, we find that Romanko is not reasonably pertinent to the problem addressed by the present application, and we agree with Appellants that it is not clear why a person of skill in the art would consider the hooks of Romanko “‘to aid in capturing different types of tissue’ as stated by the [E]xaminer.” See Reply Br. 7 Accordingly, we find that the Examiner erred in concluding that Romanko was analogous art, and we conclude that this rejection should be reversed. CONCLUSION For the reasons set forth above, we affirm the rejection of claims 1–3, 15–19, 30–33, 48, 49, and 51, and we reverse the rejections of claims 5–14, 23–29, 34–47, and 52–54.
