REUB EL T and PETER L. VERRILLO Appeal2014-005021 Application 11/689,4701 Technology Center 3700 Before JENNIFER D. BAHR, STEFAN STAICOVICI, and FREDERICK C. LANEY, Administrative Patent Judges. STAICOVICI, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Leo M. Reubelt and Peter L. Verrillo (Appellants) appeal under 35 U.S.C. § 134(a) from the Examiner's decision rejecting under 35 U.S.C. § 103(a) claims 42--46 and 48-64 as being unpatentable over Pearl (US 2001/0041940 Al, pub. Nov. 15, 2001) in view of Kropf (US 6,719,799 Bl, iss. Apr. 13, 2004).2 We have jurisdiction over this appeal under 35 U.S.C. § 6(b ). According to Appellants, the real party in interest is Tomier, Inc. Appeal Br. 2. 2 Claims 1-41and47 are cancelled. Id. at 21-22. Appeal2014-005021 Application 11/689,470 SUMMARY OF DECISION We AFFIRM-IN-PART and enter NEW GROUNDS OF REJECTION pursuant to our authority under 37 C.F.R. § 41.50(b). INVENTION Appellants' invention relates to "a reconstructive joint replacement implant and method of positioning and fitting such an implant." Spec. ,-i 2. Claims 42, 48, and 56 are independent. Claim 42 is illustrative of the claimed invention and reads as follows: 42. A method of implanting an orthopedic reconstructive joint replacement stem implant, the method comprising the steps of: resecting a head of a bone of a joint; broaching a central cavity region in the bone of the joint; evaluating a plurality of stem components each having a distal body portion connected to a proximal body portion at an angular orientation, wherein the angular orientation varies on at least t\,'1/0 of the stem components, and \'I/herein each of the plurality of stem components includes a taper extending from the proximal body portion toward the distal body portion, the taper comprising a medial curved surface and a lateral curved surface of a shape different from the medial curved surface, and wherein a shape of the medial curved surface varies on the at least two of the stem components; selecting the stem component with a fix angle that optimizes engagement of the proximal body portion with the central cavity region and with medial and lateral curved surfaces configured to mimic a geometric shape of the bone; and inserting the stem component into the central cavity region of the bone of the joint. 2 Appeal2014-005021 Application 11/689,470 ANALYSIS Claims 42, 43, and 45 Appellants have not presented arguments for the patentability of claims 43 and 45 apart from claim 42. See Appeal Br. 4-9. Therefore, in accordance with 37 C.F.R. § 41.37(c)(l)(iv) (2015), we select claim 42 as the representative claim to decide the appeal of the rejection of these claims, with claims 43 and 45 standing or falling with claim 42. The Examiner finds that Pearl discloses the claimed method of implanting an orthopedic reconstructive joint replacement stem implant including, inter alia, "providing a series of stems ( 11 a-11 d) with incrementally different superior end wall angles that may range from an acute angle of 85° in Fig. 2A to an obtuse angle of 110° [in Fig. 2D] ... for the purpose of providing a metaphyseal region that is sized and shaped to accommodate a patient's native anatomy" and "selecting the appropriate components from the available inventory for implantation" Non-Final Act. 3-5; see also Pearl iii! 29, 65; Figs. 2A-2D. According to the Examiner, "the variations from stem to stem in the series provided by Pearl include a variation in shape of the medial surface on at least two of the stem components." Non-Final Act. 5. The Examiner further finds that Pearl does not explicitly teach stem components having medial and lateral curved surfaces. Id. The Examiner thus relies upon Kropf to teach an implantable prosthesis 10 having a taper and "a medial curved surface [24] and a lateral curved surface [26], of a shape different from the medial curved surface, which are configured to mimic the geometric shape of the bone." Id. at 6; see also Kropf, Fig. 1. The Examiner concludes that it would have been obvious for a person of ordinary skill in the art to include curved lateral and 3 Appeal2014-005021 Application 11/689,470 medial surfaces, as taught by Kropf~ to Pearl's multiple stems, because such a configuration of a stem component is well known in the art (see Non-Final Act. 6) and "in order to design a prosthesis that is adapted to the respective anatomical aspect of the human bones which are to be connected therewith" (see Ans. 2). Appellants argue that Pearl's stems 11 a-11 d lack a taper including differently shaped curved lateral and medial surfaces, whereas Kropf discloses a single implant having curved medial and lateral surfaces with specific dimensions. Appeal Br. 7-8. We are not persuaded by Appellants' arguments because Appellants cannot show nonobviousness by attacking Pearl and Kropf individually when the rejection, as articulated by the Examiner, is based on a combination of Pearl and Kropf. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). In this case, the Examiner correctly relies upon Pearl to disclose a plurality of stem components with varying shaped medial and lateral surfaces (see the varying inclination angles of 35°, 40°, 45°, and 50° forming differently shaped medial and lateral surfaces in Figures 2A-2D and 3A-3D of Pearl), and Kropf to disclose that both medial and lateral surfaces on a stem component of a prosthesis are curved. See Non-Final Act. 6-7, Ans. 2. Accordingly, we agree with the Examiner "that the resulting series of stem components taught by Pearl in view of Kropf, would include a shape of the medial curved surface that varies on at least two of the stem components," as called for by claim 42. Id. Appellants next argue that the prosthetic devices as disclosed in Pearl are "merely illustrations" of stems components and thus, Pearl does not disclose a "set of prosthetic devices that are evaluated as claimed." Appeal. Br. 8. Appellants also contend that Kropf likewise "does not teach or 4 Appeal2014-005021 Application 11/689,470 suggest evaluating a plurality of stem components." Id. Once more Appellants are attacking Pearl and Kropf individually when the rejection as articulated by the Examiner is based on a combination of Pearl and Kropf. Here, the Examiner is not using Kropf s disclosure for the claimed "evaluating" step, but rather is using the disclosure of Pearl. Specifically, the Examiner is correct that as Pearl discloses selecting the appropriate components from available inventory to build an appropriate prosthesis, Pearl discloses evaluating a plurality of stem components, as called for by claim 42. See Ans. 3. For example, Pearl specifically discloses that a prosthesis is assembled from separate components, namely, stem 11, body 12, head 13, and insert 14, that are provided in various configurations. See Pearl iii! 29 ("providing a series of stems .... [choosing] [t]he selected stem lla-lld ... "), 30 ("[A] series of bodies 12a-12d are provided .... ), 36 ("[T]he head 13 is typically made available in multiplicity of sizes ... "), 38 ("A plurality of inserts 14 with various locking projection offsets can be provided ... "),and 65. Appellants also contend that the Examiner's reasoning for modifying Pearl's medial and lateral surfaces to be curved, as taught by Kropf, lacks rational underpinnings as Kropf fails to disclose that curved medial and lateral surfaces are configured to mimic the geometric shape of the bone and moreover, what benefits curved medial and lateral surfaces would provide to Pearl's stems. Appeal Br. 8; see also Ans. 2-3 (citing Kropf col. 1, 11. 46- 49). According to Appellants, the portion of Kropf cited by the Examiner to support the conclusion of obviousness does not refer to the curved surfaces to mimic the shape of the bone, but rather refers to the head adjustment to mimic the shape of the bone. Reply Br. 2-3. Although we appreciate that 5 Appeal2014-005021 Application 11/689,470 Kropf does not refer to any specific benefits that the curved medial and lateral surfaces of its shaft 12 would provide to Pearl's stems l la-1 ld (see Appeal Br. 8), nonetheless, we do not agree with Appellants' position because Kropf refers to "adaptation" of its "prosthesis" to human anatomy, whereas the prosthesis is described as having both a shaft (stem) and a dome-shaped joint head. See Kropf, col. 1, 11. 10-14 and 43-48. Furthermore, Pearl specifically discloses that the shape of the metaphyseal region of a prosthesis3 is important with respect to "accommodating the native anatomy." Pearl ii 33. Pearl further explains that its modular prosthesis is designed to "effectively replicate the anatomic position of the patient's articular surface." Id. ii 35. Accordingly, the combined teachings of Pearl and Kropf disclose selecting a stem component with curved medial and lateral surfaces that replicate human anatomy and thus, "mimic[ s] the geometric shape of the bone," as called for by claim 42. In conclusion, for the foregoing reasons, we sustain the rejection of claim 42 as being unpatentable over the combined teachings of Pearl and Kropf. Claims 43 and 45 fall with claim 42. Claim 44 The Examiner finds that Pearl fails to disclose, using a single instrument, as called for by claim 44. Non-Final Act. 5. According to the Examiner, Appellants' Specification uses the terms "ream" and "broach" interchangeably and thus the claimed limitation lacks criticality. Id. at 5-6 3 The metaphyseal region of the prosthesis corresponds to the region connecting body 12 to stem 11 and to form varying inclination angles 35°, 40°, 45°, and 50°. See Pearl, Figs. 2A-2D and 3A-3D. 6 Appeal2014-005021 Application 11/689,470 (citing Spec. iJ 63 ). The Examiner concludes that it would have been obvious to modify Pearl and use a single instrument because a person of ordinary skill in the art would have "easily recognized the benefits of combining the steps of reaming and broaching through the use of a single instrument, in order to simplify the surgical procedure and minimize invasiveness." Ans. 3. Alternatively, the Examiner takes the position that "the inherent use of a single instrument to perform broaching, as taught by Pearl, can be construed to meet this limitation since a broach is a tool that is used to shape or enlarge a hole and can therefore include the function of reaming, as claimed." Id. at 3--4. Although we appreciate the Examiner's position that using a single instrument for reaming and broaching would simplify the surgical procedure and minimize invasiveness, nonetheless, the Examiner has failed to set forth any findings as to whether the prior art discloses an instrument that can "concurrently broach and ream." Although we appreciate the Examiner's position that combining the broaching and reaming steps would provide benefits to the implantation method of Pearl, as modified by Kropf, nonetheless, the Examiner has not set forth any findings that a single instrument that can both ream and broach is taught in the prior art. Reamers and broaches are known to be separate instruments that have different functions for processing materials. See Pearl iii! 58, 60, 62, 64. Thus, the Examiner has not made the initial factual findings required to demonstrate a prima facie case of obviousness. See In re Warner, 379 F.2d 1011, 1017 (CCPA 1967). As to the Examiner's position that Pearl's tool can inherently perform both reaming and broaching because they represent the same process, we do 7 Appeal2014-005021 Application 11/689,470 not agree because Pearl specifically discloses different tools for performing different functions, that is, a reamer for reaming a canal and a broach for "follow[ing] the reamed canal." Pearl iii! 58, 60, 64. "The mere fact that a certain thing may result from a given set of circumstances is not sufficient." In re Robertson, 169 F.3d 743, 745 (Fed. Cir. 1999) (citations omitted). Therefore, we agree with Appellants that Pearl fails to disclose necessarily using a single instrument for concurrently reaming and broaching. See Reply Br. 3-4. In conclusion, for the foregoing reasons, we do not sustain the rejection of claim 44 under 35 U.S.C. § 103(a) as unpatentable over Pearl and Kropf. Claim 46 Appellants argue that neither Pearl nor Kropf discloses the limitation "inserting the proximal body portion of the stem implant into the central cavity region of the bone of the joint in a direction to avoid the supraspinatus."4 Appeal Br. 11. We do not agree with Appellants' position because the Examiner finds that "it is inherent that the proximal portion of the stem implant of Pearl is inserted into the central cavity region of the bone of the joint in a direction to 4 The supraspinatus is "a muscle of the back of the shoulder that arises from the supraspinous fossa of the scapula, that inserts into the top of the greater tubercle of the humerus, that is one of the muscles making up the rotator cuff of the shoulder, and that rotates the humerus laterally and helps to abduct the arm." Merriam-Webster Medical Dictionary 22, 2016). 8 Appeal2014-005021 Application 11/689,470 avoid the supraspinatus." Ans. 4. An artisan must be presumed to know something about the art apart from what the references disclose. See In re Jacoby, 309 F.2d 513, 516 (CCPA 1962). In this case, a person of ordinary skill in the art of orthopedic surgery would have understood to avoid the supraspinatus when operating on a patient to insert the implant of Pearl, as modified by Kropf, to avoid injury to the supraspinatus and, as the Examiner correctly explains, "deficient rotator cuff muscles can produce poor results and complications." Ans. 4. Appellants have not persuasively shown error in the Examiner's findings and reasoning. In conclusion, for the foregoing reasons, we also sustain the rejection of claim 46 as unpatentable over the combined teachings of Pearl and Kropf. Claims 48, 49, 51, 54, and 62 Appellants have not presented arguments for the patentability of claims 49, 51, 54, and 62 apart from claim 48. See Appeal Br. 11-14. Therefore, we select claim 48 as the representative claim to decide the appeal of the rejection of these claims, with claims 49, 51, 54 and 62 standing or falling with claim 48. Independent claim 48 requires, inter alia, each of a plurality of stem components to include a "proximal body portion ... comprising a bearing surface adapted to support a head component having a geometric head center ... wherein the head center is spaced from the longitudinal axis ... at a medial offset distance" and "at least two of the plurality of stem components include different medial offset distances." Appeal Br. 22. The Examiner finds that "the head center of Pearl is [] spaced from a longitudinal axis of the distal body portion at a medial offset distance." 9 Appeal2014-005021 Application 11/689,470 Non-Final Act. 9. The Examiner further takes the position that as "the limitations regarding the head component are not positively claimed, they are given little patentable weight." Id. at 10. According to the Examiner, Id. [T]he device taught by Pearl is at least fully capable of supporting a head component having a geometric head center located within the proximal portion, when the head component is engaged with the bearing surface, and spaced from a longitudinal axis extending through the distal body by various medial offset distances, as claimed by applicant. In addition to the arguments presented supra with regards to the rejection of claim 42, which we have found unpersuasive, Appellants further argue that neither Pearl nor Kropf discloses the above recited limitations. Appeal Br. 12-13. We agree with the Examiner's position for the following reasons. The fact that a geometric head center and a medial offset distance are not specifically mentioned in either Pearl or Kropf does not, without more, establish that the Examiner erred. What a reference teaches or suggests must be examined in the context of the knowledge, skill, and reasoning ability of a skilled artisan and is not limited to what a reference specifically "talks about" or what is specifically "mentioned" or "written" in the reference. Syntex (U.S.A.) LLC v. Apotex, Inc. 407 F.3d 1371, 1380 (Fed. Cir. 2005). "[A] person of ordinary skill is also a person of ordinary creativity, not an automaton." KSR v. Teleflex, 550 U.S. 398, 421 (2007). In this case, as all geometric objects have a geometric center, Pearl's head 13 likewise has a geometric head center. Furthermore, as Pearl's head 13 is laterally offset from stem 11, the geometric head center is likewise laterally offset by a distance from longitudinal axis SCL of stem 11, that is, by a medial offset 10 Appeal2014-005021 Application 11/689,470 distance. 5 We further agree with the Examiner that Pearl discloses a variety of head inserts 14 that allow head 13 to be located at various offset positions with respect to body 12. Non-Final Act. 8-9; see also Pearl ,-i,-i 37, 38, 47, and 48. Therefore, as the location of head 13 changes among different positions relative to stem 11, the location of the geometric center also changes position relative to stem 11, and thus, the distance between the geometric center of head 13 to the longitudinal axis SCL of stem 11 will change accordingly, to thus obtain a plurality of stem components having different medial offset distances, as called for by claim 48. As such, the Examiner is on solid footing to shift the burden to Appellants to prove that Pearl's plural prostheses do not possess a geometric head center that is spaced from the longitudinal axis of the stem by a variable medial offset distance. In re Spada, 911 F.2d 705, 708 (Fed. Cir. 1990). Appellants have not set forth persuasive evidence or reasoning to show otherwise. Lastly, we agree with the Examiner's assertion that the limitation of a "proximal body portion ... adapted to support a head component having a geometric center" is a functional limitation. See Appeal Br. 22. Our reviewing court has stated that the claim term "adapted to" "is frequently used to mean 'made to,' 'designed to,' or 'configured to,' ... [a]lthough the phrase can also mean 'capable of or 'suitable for."' In re Giannelli, 739 F.3d 1375, 1379 (Fed. Cir. 2014) (citing Aspex Eyewear, Inc. v. Marchan Eyewear, Inc., 672 F.3d 1335, 1349 (Fed. Cir. 2012)). In this case, 5 Appellants' Specification describes the medial offset distance as the "distance between the head center and the closest point along the longitudinal axis [of the distal stem portion]." Spec. ,-i 80; see also reference number 207' in Appellants' Figure l lA. 11 Appeal2014-005021 Application 11/689,470 Appellants' Specification describes an implant 150, 180 having a proximal portion 154, 184 with a coupling device 158, 188 for attaching a humeral or femoral head. See Spec. iii! 72, 74, 75, 77; Figs. 9A, 9B. As such, because Pearl's body portion 12 locks head 13 in a lateral offset position using insert 14, we agree with the Examiner that the term "adapted to" means "capable of' in that the "series of stems of Pearl [are] at least fully capable of supporting a head component having a geometric head center that is medially offset at different distances as claimed by [A ]pplicant." Ans. 4. Furthermore, we note that Pearl's proximal portion of body 12 is "made to," "designed to," or "configured to" support a head 13 having a geometric head center located at a medial offset distance, as called for by claim 48. Specifically, Pearl's proximal portion of body 12 is configured to include aperture 21 for receiving locking projection 17 of insert 14 that attaches head 13 in a lateral offset position with respect to the longitudinal axis SCL of stem 11. See Pearl iii! 36, 38; Figs. IA, lB; see also Final Act. 8-9. In this manner, Pearl's proximal portion of body 12 and insert 14 are configured to support head 13 just as Appellants' proximal portion 154, 184 and coupling device 158, 188 are configured to support a humeral or femoral head. In conclusion, for the foregoing reasons, we sustain the rejection of claim 48 as unpatentable over the combined teachings of Pearl and Kropf. Claims 49, 51, 54, and 62 fall with claim 48. Claims 5 0, 5 2, and 64 With respect to the rejection of claims 50, 52, and 64, Appellants argue that the Examiner's modification of Pearl's prostheses, to include 12 Appeal2014-005021 Application 11/689,470 lateral curved surfaces, as taught by Kropt: would not have been obvious to a person of ordinary skill in the art because Kropf does not refer to any specific benefits that the curved lateral surfaces of its shaft 12 would provide to Pearl's stems 11 a-11 d and furthermore, Kropf fails to disclose "surfaces of the shaft 12 [as] being configured to mimic the geometric shape of a bone." Appeal Br. 14-15. Appellants further argue that the Examiner's reasoning for making the combination lacks rational underpinnings. Id. at 15. We are not persuaded by Appellants' arguments for the reasons set forth supra in the rejection of claim 42. Accordingly, we sustain the rejection of claims 50, 52, and 64 over the combined teachings of Pearl and Kropf. Claim 53 Claim 53 depends from independent claim 48 and adds the limitation that "the medial offset distance of each of the three stem components is at least two millimeters different from the medial offset distance of the other two of the three stem components." Appeal Br. 23. The Examiner takes the position that although Pearl does not expressly teach three stem components having the claimed medial offset relationship, nonetheless, it would have been obvious to one having ordinary skill in the art at the time of the invention to specify a distance between the offset positions of Pearl, in order to accommodate the native anatomy, particularly since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. Non-Final Act. 9 (citing Jn re Boesch, 617 F.2d 272 (CCPA 1980)). 13 Appeal2014-005021 Application 11/689,470 Appellants argue that because Pearl does not disclose medial offset values, but rather head-to-stem angles, it would not have been obvious to optimize the medial offset distances of Pearl's stems, as modified by Kropf. See Appeal Br. 16. Although we appreciate that Pearl discloses a plurality of stem components having different medial offset distances, nonetheless, the Examiner has not shown where Pearl discloses three stem components having the claimed medial offset distance relationship, provides sufficient information to permit values to be determined, or otherwise provides support for the finding that a person of ordinary skill would have considered the claimed medial offset distance relationship between three stem components to be a result-effective variable. As such, we are not persuaded that the medial offset distance relationship between the claimed three stems is a result-effective variable, rendering its optimization within the grasp of one of ordinary skill in the art. Therefore, we do not sustain the rejection of claim 53 as unpatentable over the combined teachings of Pearl and Kropf. Claim 56, 59, 60, and 63 With respect to the rejection of claims 56, 59, 60, and 63, Appellants rely on the same arguments, discussed supra, and asserted against the rejection of claim 42. See Appeal Br. 17-19. Accordingly, for the same reasons as discussed above, we likewise sustain the rejection of claims 56, 59, 60, and 63 over the combined teachings of Pearl and Kropf. 14 Appeal2014-005021 Application 11/689,470 Claims 55 and 61 Claim 55 depends from independent claim 48 and adds the limitation that "the distal body portion and the proximal body portion comprise a single unitary member." Appeal Br. 23. Claim 61 includes the same limitation as claim 55, but depends from independent claim 56. Id. at 24. The Examiner finds that "the stem components taught by Pearl appear to comprise a single unitary member, at least when assembled." Non-Final Act. 7. The Examiner also finds that Kropf discloses "that the use of a monolithic stem is also clearly well known in the art." Ans. 5. Thus, the Examiner attempts to present an alternative rejection in concluding that it would have been obvious "to specify that the distal body portion and the proximal body portion comprise a single unitary member, since it has been held that forming in one piece an article which has formerly been formed in two pieces and put together involves only routine skill in the art." Id (citing Howard v. Detroit Stove Works, 150 U.S. 164 (1893)). During examination, "claims ... are to be given their broadest reasonable interpretation consistent with the specification, [ ] and ... claim language should be read in light of the specification as it would be interpreted by one of ordinary skill in the art." In re Bond, 910 F .2d 831, 833 (Fed. Cir. 1990) (Internal citation and quotations omitted). In this case, an ordinary and customary meaning of the term "unitary" is "having the character of a unit: UNDIVIDED, WHOLE." Merriam Webster's Collegiate Dictionary (l01h ed. 1997). As such, we agree with Appellants that the separate stem 11 and body 12 units of Pearl, when assembled, do not form a unitary unit because they can be disassembled, i.e., divided. Such an interpretation is consistent with Appellants' Specification that describes the 15 Appeal2014-005021 Application 11/689,470 proximal and distal body components as forming a "single piece." See Spec. 25, claim 7. Furthermore, the Examiner's reliance on Howard v. Detroit Stove Works amounts to a per se rule that eliminates the need for fact- specific analysis of claims and prior art and is legally incorrect. Our precedents do not establish any rules of obviousness, just as those precedents themselves expressly declined to create such rules. In re Ochiai, 71 F.3d 1565, 1572 (Fed. Cir. 1995). In conclusion, for the foregoing reasons, we do not sustain the rejection of claims 55 and 61 as unpatentable over the combined teachings of Pearl and Kropf. Claim 57 and 58 With respect to the rejection of dependent claims 57 and 58, Appellants make the same arguments, discussed supra, and advanced against the rejection of claim 50, 52, and 54. See Appeal Br. 19-20. Accordingly, for the same reasons as discussed above, we likewise sustain the rejection of claims 57 and 58 over the combined teachings of Pearl and Kropf. NEW GROUNDS OF REJECTION We make the following new grounds of rejection pursuant to 37 C.F.R. § 41.50(b). Claims 53, 55, and 61 are rejected under 35 U.S.C. § 103(a) as unpatentable over Pearl and Kropf. We adopt the Examiner's findings and conclusions with respect to the limitations of independent claims 48 and 56 noted in the Non-Final Action, 16 Appeal2014-005021 Application 11/689,470 dated February 15, 2013, and as explained in our discussion above. See Non-Final Act. 7-15. Claim 53 depends from independent claim 48 and adds the limitation that "the medial offset distance of each of the three stem components is at least two millimeters different from the medial offset distance of the other two of the three stem components." Appeal Br. 23. Pearl discloses positioning insert 14 at 2 mm increments to obtain a plurality of locations for head 13. See Pearl ii 50, Fig. 8. For example, each of the locations of insert 14 in the top row of Pearl's Figure 8 corresponds to a separate stem/prosthesis. As such, if inserts 14 of the three stems/prostheses are located 2 mm apart, then it stands to reason that heads 13 of the three stems/prostheses will also be 2 mm apart, and thus the medial offset distance between the three stems/prostheses will also be 2 mm apart, as called for by claim 53. Claim 55 depends from independent claim 48 and adds the limitation that "the distal body portion and the proximal body portion comprise a single unitary member." Appeal Br. 23. Claim 61 includes the same limitation as claim 55, but depends from independent claim 56. Id. at 24. Pearl discloses that, as an alternative to separate stem, body, head, and insert portions, a "wide array of single piece stem-body units may be one piece." Pearl ii 65 (emphasis added). Thus, Pearl discloses a single, unitary stem arrangement, as called for by claims 55 and 61. 17 Appeal2014-005021 Application 11/689,470 SUMMARY The Examiner's decision to reject claims 42--46 and 48-64 is affirmed as to claims 42, 43, 45, 46, 48-52, 54, 56-60, and 62-64 and reversed as to claims 44, 53, 55, and 61. We enter a new ground of rejection of claims 53, 55, and 61 under 35 U.S.C. § 103(a) as unpatentable over Pearl and Kropf. This decision contains a new ground of rejection pursuant to 37 C.F.R. § 41.50(b). 37 C.F.R. § 41.50(b) provides "[a] new ground of rejection pursuant to this paragraph shall not be considered final for judicial review." 37 C.F.R. § 41.50(b) also provides: When the Board enters such a non-final decision, the appellant, within two months from the date of the decision, must exercise one of the following two options with respect to the new ground of rejection to avoid termination of the appeal as to the rejected claims: (1) Reopen prosecution. Submit an appropriate amendment of the claims so rejected or new Evidence relating to the claims so rejected, or both, and have the matter reconsidered by the Examiner, in which event the prosecution will be remanded to the Examiner. The new ground of rejection is binding upon the examiner unless an amendment or new Evidence not previously of Record is made which, in the opinion of the examiner, overcomes the new ground of rejection designated in the decision. Should the examiner reject the claims, appellant may again appeal to the Board pursuant to this subpart. (2) Request rehearing. Request that the proceeding be reheard under § 41.52 by the Board upon the same Record. The request for rehearing must address any new ground of rejection and state with particularity the points believed to have been misapprehended or overlooked in entering the new ground of 18 Appeal2014-005021 Application 11/689,470 rejection and also state all other grounds upon which rehearing is sought. Further guidance on responding to a new ground of rejection can be found in the Manual of Patent Examining Procedure§ 1214.01. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § l .136(a)(l )(iv).
