SCHULMAN __________ Appeal 2011-009420 Application 11/173,863 Technology Center 3700 __________ Before ERIC GRIMES, MELANIE L. McCOLLUM, and JACQUELINE WRIGHT BONILLA, Administrative Patent Judges. McCOLLUM, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims to a biocompatible medical apparatus. The Examiner has rejected the claims as anticipated or obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. STATEMENT OF THE CASE Claims 1, 3-6, and 13-17 are pending and on appeal (App. Br. 2). Claims 1, 3, 4, 6, and 13 are representative and read as follows: Appeal 2011-009420 Application 11/173,863 2 1. A hermetic implantable, biocompatible medical apparatus, comprising a plurality of processing electronics, configured to sense tissue signals, said apparatus comprising: a ceramic case having a wall with an outer surface that encloses said processing electronics; a plurality of electrodes in communication with said processing electronics; a plurality of feedthroughs in said ceramic case, each feedthrough adapted to receive a respective electrode; and an antenna comprised of silver, said antenna the product of thermal processing of silver paste, bonded to the outer surface of the wall of said ceramic case, said antenna in electrical communication with said processing electronics. 3. The apparatus according to claim 1 further comprising a metal interface ring and a braze ring, wherein said metal interface ring is bonded to said ceramic case by said braze ring. 4. The apparatus according to claim 3 further comprising a diaphragm and a weldment, wherein said diaphragm is bonded to said metal interface ring by said weldment. 6. The apparatus according to claim 1, further comprising: a flex connector containing a plurality of electrical conductors, wherein said electrical conductors are each attached to one of said electrodes; and an array of neuro-needles each attached to one of said plurality of electrical conductors. 13. A biocompatible motor cortex stimulator or sensor comprising: processing electronics; a ceramic case having a wall with an outside surface that encloses said processing electronics; at least one electrode in electrical communication with said processing electronics; at least one feedthrough located in the wall of said ceramic case; said electrically conductive feedthrough containing said electrode; and the stimulator or sensor further comprising an antenna, the product of thermal processing of silver paste, said antenna bonded to the outside Appeal 2011-009420 Application 11/173,863 3 surface of the wall of said ceramic case, the antenna in electrical communication with said processing electronics. Claims 1 and 13 stand rejected under 35 U.S.C. § 102(b) as anticipated by or under 35 U.S.C. § 103(a) as obvious over Sun 1 (Ans. 4). Claims 1, 3, 4, and 13-15 stand rejected under 35 U.S.C. § 103(a) as obvious over Fischer 2 in view of Sun (Ans. 7). Claims 5, 6, 16, and 17 stand rejected under 35 U.S.C. § 103(a) as obvious over Fischer in view of Sun and Burgert 3 (Ans. 17). Claims 1, 3-6 and 13-17 stand rejected under 35 U.S.C. § 103(a) as obvious over Burgert in view of Fischer and Sun (Ans. 11). I The Examiner finds that “Sun provides an implantable stimulator . . . having an antenna on the exterior of the housing . . . , where the housing is ceramic . . . , a feedthrough, 50, with electrode/conductor/pin, 52, [and] the broadly claimed „components‟” (Ans. 4). The Examiner also finds that Sun “states that the antenna is a noble metal, which silver is a noble metal, and provides an example of using a noble metal, such as silver” (id.). The Examiner notes that “the claim contains a product by process limitation, „the product of thermal processing of silver paste,‟” but notes that the “patentability of a product does not depend on its method of production” (id.). 1 Sun et al., US 5,861,019, Jan. 19, 1999. 2 Fischer, US 4,785,827, Nov. 22, 1988. 3 Johann Burgert et al., Embedded electronics for a 64-channel wireless brain implant, in Microrobotics and Microassembly III (Proceedings of SPIE) 4568: 124-134 (2001). Appeal 2011-009420 Application 11/173,863 4 Alternatively, the Examiner finds that “Sun discloses the claimed invention except for the antenna being a silver antenna” (id.). The Examiner relies on Campbell, 4 Tai, 5 or Schwartz 6 as providing evidence that it was known in the art to use “a silver antenna external to the implantable housing” (id. at 7). The Examiner concludes: It would have been obvious to one having ordinary skill in the art at the time the invention was made to include in the noble antenna of Sun, the use of a silver antenna as taught by Campbell, Tai, or Schwartz, since it was well known in the art that implantable devices use silver antennas to provide the predictable results of a noble metal, such as silver, that is biocompatible and easily manufactured and a relatively inexpensive noble metal. (Id.) Findings of Fact 1. Sun is directed to a “telemetry antenna for an implantable medical device” (Sun, col. 1, ll. 25-27). 2. Sun discloses an “implantable medical device microstrip patch antenna [that] advantageously extends over the available surface area of [a] hermetically sealed enclosure housing” (id. at col. 5, ll. 44-46). 3. Sun states: At present, a wide variety of implanted medical devices are commercially released or proposed for clinical implantation. Such medical devices include implantable cardiac pacemakers as well as implantable cardioverter-defibrillators, pacemaker- cardioverter-defibrillators, drug delivery pumps, cardiomyo- 4 Campbell et al., US 7,289,853 B1, Oct. 30, 2007. 5 Tai et al., US 2006/0271129 A1, Nov. 30, 2006. 6 Schwartz, US 6,746,404 B2, Jun. 8, 2004. Appeal 2011-009420 Application 11/173,863 5 stimulators, cardiac and other physiologic monitors, nerve and muscle stimulators, deep brain stimulators, cochlear implants, artificial hearts, etc. (Id. at col. 4, l. 64, to col. 5, l. 4.) 4. Sun also states that the “following description is directed to various preferred embodiments of the invention implemented in the housing of a cardiac pacemaker or pacemaker-cardioverter-defibrillator IPG” (implantable pulse generator), but that “those of skill in the art will be readily able to adapt the teachings found herein to the other implantable medical devices listed above and others to be devised” (id. at col. 8, ll. 5-12, & col. 2, ll. 7-8). 5. In particular, Sun discloses: IPG 12 is electrically coupled to the heart 18 of the patient 10 through pace/sense electrodes and lead conductor(s) of at least one cardiac pacing lead 14 in a manner known in the art. The IPG 12 contains an operating system that may employ a microcomputer or a digital state machine for timing sensing and pacing functions in accordance with a programmed operating mode. The IPG 12 also contains sense amplifiers for detecting cardiac signals, patient activity sensors or other physiologic sensors for sensing the need for cardiac output, and pulse generating output circuits for delivering pacing pulses to at least one heart chamber of the heart 18 under control of the operating system in a manner well known in the prior art. (Id. at col. 8, ll. 27-39.) 6. Sun also discloses: FIGS. 9 and 10 depict top and side views . . . of a breadboard microstrip RF telemetry antenna 128 that is tested in the test setup of FIG. 11. In this breadboard, a circular, flat radiator patch layer 130 is formed of approximately 0.001 inch thick Appeal 2011-009420 Application 11/173,863 6 sheet of silver having a diameter of 1.5 inches that is fired upon the upper surface of a flat dielectric substrate layer 136. (Id. at col. 12, l. 63, to col. 13, l. 2.) 7. In addition, Sun discloses: FIGS. 16 and 17 depict a third embodiment of an RF telemetry antenna 28 with the radiator patch layer 30, 30' formed on the exterior surface of a dielectric, ceramic, housing 13' of an IPG 12 and having a ground plane layer 48' formed as a conductive layer on the interior surface of the IPG housing 13'. . . . It will be understood that the ground plane layer 48' is insulated electrically from interior circuit components within the IPG housing. This embodiment also illustrates an alternative form of the feedthrough pin 52 which fills the dielectric layer hole 38 and is abutted against the interior surface of the radiator patch layer 30, 30'. (Id. at col. 15, ll. 46-61.) 8. Sun also discloses: In each of the preferred embodiments, the radiator patch layer is preferably formed of a stable, bio-compatible, conductive layer that is applied as a thin plate or thin film deposition over the exterior surface of the dielectric layer. The radiator patch layer may be formed of a noble metal, e.g. gold, platinum, niobium, or an alloy thereof. (Id. at col. 16, ll. 36-41.) 9. Campbell discloses “creat[ing] an antenna by selectively plating highly conductive metals (such as silver or gold) onto the outside surface of the Wireless Pacemaker Housing 128” (Campbell, col. 12, ll. 58-61). 10. In particular, Campbell discloses that “a highly conductive metal, such as gold, can be bonded to the surface of the Wireless Pacemaker Housing 128 to form a modified loop antenna” (id. at col. 12, l. 67, to col. 13, l. 2). Appeal 2011-009420 Application 11/173,863 7 11. Campbell also discloses that this “method is also effective if Selective Double Plating 182 is used, wherein a very high conductivity metal is selectively plated onto the Wireless Pacemaker Housing 128, such as silver, and a protective metal is plated over it which is compatible with implantation, such as gold” (id. at col. 13, ll. 45-49). 12. Schwartz discloses “a telemetric medical system comprising a telemetric medical sensor for implantation in a patient‟s body for measuring a parameter therein” (Schwartz, col. 2, ll. 36-38). 13. In particular, Schwartz discloses: “The sensor 50 . . . includes an antenna coil 68 which is operatively connected to the internal components of the sensor 50 by an antenna lead 70. . . . The material used for the antenna wire is approximately 90% silver content with a cladding of platinum iridium of approximately 10% content.” (Id. at col. 8, ll. 55-61.) Analysis Appellant argues that “Sun teaches an antenna and not a hermetic enclosure” (App. Br. 4). In addition, Appellant argues that Sun does not teach “a ceramic case that encloses electronic components” (id.). We are not persuaded. Sun is directed to an antenna (Finding of Fact (FF) 1). However, Sun clearly discloses extending the antenna over a hermetically sealed enclosure housing (FF 2). In particular, Sun discloses “an RF telemetry antenna 28 with the radiator patch layer 30, 30' formed on the exterior surface of a dielectric, ceramic, housing 13' of an IPG 12,” and “interior circuit components within the IPG housing” (FF 7; see also FF 5). Sun may not specifically recite the electronic components recited in paragraph 17 of the Appeal 2011-009420 Application 11/173,863 8 Specification. However, claims 1 and 13 merely recite “processing electronics.” We do not interpret this language to require the particular electronic components recited in paragraph 17 of the Specification. Appellant also argues that “Sun does not teach a stimulator” (App. Br. 4). We are not persuaded. We note initially that claim 1 does not recite a stimulator. In addition, we note Appellant‟s admission that pacemaker-cardioverter-defibrillators, which are disclosed in Sun (FF 4), “do provide stimulation/sensing” (Reply Br. 4). Furthermore, Sun discloses that “those of skill in the art will be readily able to adapt [its] teachings . . . to . . . other implantable medical devices,” such as nerve stimulators and deep brain stimulators (FF 3-4). In addition, Appellant argues that “Sun does not teach a silver antenna” and, in fact, teaches away from implanting a silver antenna (App. Br. 4 & 9). We are not persuaded. Sun discloses: “[T]he radiator patch layer is preferably formed of a stable, bio-compatible, conductive layer. . . . The radiator patch layer may be formed of a noble metal, e.g. gold, platinum, niobium, or an alloy thereof.” (FF 8.) As noted by Appellant (App. Br. 5), Sun does not specifically list silver, except in the context of a breadboard (FF 6). In addition, Appellant provides a Declaration 7 stating: “[T]he term „noble metal‟ means a non- reactive metal in a specific environment. . . . Silver . . . reacts when implanted. . . . Silver is not considered noble by Sun. . . .” (Dec. 1 ¶ 4.) 7 Declaration Under 37 CFR 1.132 of Dr. Guangqiang Jiang dated April 7, 2010. Appeal 2011-009420 Application 11/173,863 9 However, the Examiner provides evidence to support his finding that “the use of a silver antenna external to the implantable housing” was known in the art (Ans. 7). We conclude that at least Campbell 8 and Schwartz support this finding (FF 9-13). As noted by Appellant (Reply Br. 5-6), both Campbell and Schwartz teach silver covered by another metal (FF 11 & 13). However, we do not interpret claims 1 and 13 to exclude silver coated with another metal. Therefore, we conclude that the preponderance of the evidence of record supports the Examiner‟s conclusion that Sun, as evidenced by Campbell and Schwartz, teaches or suggests an antenna comprised of silver. Conclusion The evidence supports the Examiner‟s conclusion that Sun teaches or suggests claims 1 and 13. We therefore affirm the rejection of claims 1 and 13 over Sun. II The Examiner relies on Fischer for disclosing “a ceramic outer surface . . . , with brazed weld ring (e.g. 20), metal interface ring (e.g. 36/38) and diaphragm (e.g. . . . 32) with electronic circuitry inside the housing (e.g. 11a . . . ), with feedthrough and lead/electrode/conductor (e.g. . . . 25)” (Ans. 7). The Examiner finds that “Fischer does not disclose the antenna on the 8 Appellant argues that “Campbell is unavailable as prior art having been filed on 8/30/04, while Appellant filed 7/1/05 with a priority claim to a provisional filing on 7/7/04” (Reply Br. 5). However, the Examiner notes that Campbell “claims priority back to provisional applications” (May 24, 2011, Patent Office comm.), which were filed on March 23, 2004, and August 28, 2003. Thus, we conclude that Appellant has not established that Campbell is unavailable as prior art. Appeal 2011-009420 Application 11/173,863 10 outside of the ceramic housing . . . and diaphragm welded to the metal interface ring” (id. at 7-8). The Examiner relies on Sun for teaching “that it is known to use a noble metal antenna, such as silver, on the exterior of the ceramic case” (id. at 8). The Examiner concludes: It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the IMD as taught by Fischer, with the exterior silver antenna as taught by Sun, since such a modification would provide an IMD with a noble metal antenna, such as silver, on the exterior of the ceramic case in order to provide the predictable results of allowing the system to operate with enhanced data bit rates and low error rates over a long distance and to minimize power consumption. (Id.) Alternatively, the Examiner concludes that it would have been obvious “to include in the noble antenna of Fischer in view of Sun, the use of a silver antenna, since it was well known in the art . . . that implantable devices use silver antennas,” as evidenced by Campbell, Tai, and Schwartz (id. at 8 & 11). In addition, the Examiner concludes: [I]t would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the medical device as taught by . . . Fischer and Sun with welding the interface ring to the diaphragm (a weldment) since it was known in the art that hermetic implantable devices use welding to weld metal rings to a diaphragm/lid of the housing to provide the predictable results of a secure connection that is easily manufactured and provides a hermetic seal. (Id. at 8.) Appeal 2011-009420 Application 11/173,863 11 Additional Findings of Fact 14. Fischer “relates to housings for electronic circuitry adapted to be used subcutaneously” (Fischer, col. 1, ll. 5-7). 15. Fischer discloses: The housing assembly 10 comprises a container sub- assembly 14 comprising (1) a dish-like ceramic portion 15 . . . and (2) a continuous metal sealing flange 20. The metal sealing flange 20 includes first and second portions 21 and 22 disposed at about a right angle to each other. The first portion 21 of the sealing flange 20 . . . is brazed along its entire length to a lip 23 around the periphery of the ceramic portion 15. (Id. at col. 2, l. 62, to col. 3, l. 5.) 16. Fischer also discloses: The housing assembly 10 also comprises a base subassembly 30 comprising (1) a plate-like ceramic portion 32 . . . and (2) a continuous metal sealing flange 36. The metal sealing flange 36 includes first and second portions 37 and 38 disposed at about a right angle to each other. The first portion 37 . . . is brazed to the ceramic portion 32. (Id. at col. 3, ll. 13-22.) 17. In addition, Fischer discloses: [T]he first and second portions 37 and 38 of the sealing flange 36 on the base subassembly 30 are adapted to nest with the first and second portions 21 and 22 of the sealing flange 20 on the container subassembly 14 with the inner surfaces of the ceramic portions 15 and 32 adjacent, and the second portions 22 and 38 of the nested sealing flanges 36 and 20 positioned closely adjacent and projecting along the periphery of the ceramic portion 32 of the base subassembly 30 to a position with their distal edges generally aligned and spaced from the ceramic portion 32 where they can be laser or electron beam welded together entirely around the sealing flanges 20 and 36 to form a weld bead 42. Appeal 2011-009420 Application 11/173,863 12 (Id. at col. 3, ll. 31-44.) Analysis Appellant traverses the rejection of claims 1 and 13 based on the alleged failure to teach or suggest silver (App. Br. 10). We are unpersuaded by this argument for the reasons discussed above. With regard to claims 3 and 4, inter alia, Appellant also argues: Neither Fisher nor Sun nor their combination teach a metal interface ring and a braze ring, wherein the metal interface ring is bonded to the ceramic case. Also, Fisher and Sun in combination do not teach a diaphragm and a weldment, where the diaphragm is bonded to the metal interface ring by the weldment. (App. Br. 10.) We are not persuaded. The Examiner considers metal sealing flange 36 to be the metal interface ring and metal sealing flange 20 to be the braze ring (Ans. 7). Fischer discloses that sealing flange 20, which is brazed to a dish-like ceramic portion 15 (FF 15), is welded to sealing flange 36 (FF 17). Thus, Fischer‟s sealing flange 36 is bonded to ceramic portion 15 through sealing flange 20. The Examiner considers ceramic portion 32 to be the diaphragm (Ans. 7). Fischer discloses that metal interface ring 36 “is brazed to the ceramic portion 32” (FF 16). The Examiner finds that Fischer does not disclose the claimed weldment, but concludes that welding would have been obvious (Ans. 7-8). Appellant has not adequately explained why this conclusion is in error. Appeal 2011-009420 Application 11/173,863 13 Conclusion The evidence supports the Examiner‟s conclusion that Fischer and Sun suggest claims 1 and 13. We therefore affirm the obviousness rejection of claims 1 and 13 over Fischer and Sun. The evidence also supports the Examiner‟s conclusion that Fischer and Sun suggest claims 3 and 4. We therefore affirm the obviousness rejection of claims 3 and 4 over Fischer and Sun. Claims 14 and 15 are argued with and therefore fall with claims 3 and 4. 37 C.F.R. § 41.37(c)(1)(vii). III In rejecting claims 5, 6, 16, and 17, the Examiner additionally relies on Burgert for teaching “that it is known to provide from the implant 64 connections/feedthroughs for connection to 64 amplifiers and hence 64 conductors/electrodes . . . , with a flex connector . . . containing electrical conductors . . . for connection to an array of neuro-needles” (Ans. 17). The Examiner concludes: It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the IMD as taught by the modified Fischer, with the 64 feedthroughs with an array of neuro-needles attached to an electrical conductor and a flex connector containing the electrical conductor for connection to the feedthrough conductor/electrode as taught by Burgert, . . . to provide the predictable results of a sensor array that reduces the occurrence of infection and tissue damage at the site of measurement and facilitates the surgical implantation of the array. (Id. at 17-18.) Appeal 2011-009420 Application 11/173,863 14 Additional Findings of Fact 18. Burgert discloses “a surgically implantable device for the study of neural activity in the brain” (Burgert 124: Abstract). 19. In particular, Burgert discloses that an “8x8 array of electrodes collects intra-cortical neural signals and connects them to an analog front end,” which amplifies and digitizes the signals (id.). 20. Burgert also discloses that a “flex circuit connector provides mechanical isolation between the brain and the electronics” (id.). 21. In addition, Burgert discloses: “This array, coupled with a flexible connector we have designed, should also reduce the occurrence of infection and tissue damage at the site of the measurement. This new connector system should also facilitate the surgical implantation of the array, a task that is quite difficult with current systems.” (Id. at 125.) 22. Burgert also discloses: “The 8 by 8 stainless-steel, electrode array serves as the sensor for the system; each electrode is electrically- insulated except at its tip, which is platinum coated (Fig. 1). Each electrode is then connected to a separate analog channel by a trace on the flexible connector.” (Id.) 23. In addition, Burgert discloses: The 8x8 electrode array was manufactured out of a piece of 4140 stainless steel using wire EDM (electron discharge machining). . . . The array was then electroplated with platinum for conductivity. A square piece of Kapton polyimide with 64 holes drilled in it was dropped over the array and secured to each electrode with epoxy, then the base of the array was cut off using EDM to electrically isolate the electrodes, leaving short stubs protruding from the back of the polyimide square. . . . The end of the flexible connector was then aligned with the Appeal 2011-009420 Application 11/173,863 15 stubs of the isolated electrodes, via 64 drilled holes, and hand- soldered in place. (Id. at 127.) 24. Burgert also discloses: The connector between the array and the electronics is a flex circuit board: 64 traces that connect the solder pads at the array end to the electronics are etched on a sheet of Kapton. The traces are connected to the electronics by a fine-pitch surface- mount connector. The flex circuit board provides fairly good flexibility in one plane since it will bend up and down easily. (Id. at 128.) Analysis Appellant argues that, “as Dr. Jiang points out in his Declaration of April 7, 2010, Burgert casually mentions a flex connector and offers no teaching or enablement or figures to clarify what the phrase „flex circuit connector‟ means” (App. Br. 13). We are not persuaded. First, we do not agree that Burgert merely casually mentions the flex circuit connector (see FF 20-24). In particular, Burgert states that its connector “is a flex circuit board,” which “provides fairly good flexibility in one plane since it will bend up and down easily” (FF 24). Although Burgert may not disclose a flex connector as depicted in Appellant‟s Figure 3, representative claim 6 generally recites a flex connector. In addition, even if Burgert does not specifically teach how to choose the materials of construction and incorporate a conductor (Dec. 2), Appellant‟s argument does not persuade us that it would not have been within the ordinary level of skill in the art to practice Burgert‟s invention. Appeal 2011-009420 Application 11/173,863 16 Appellant also argues: “No teaching, suggestion or reason to combine is offered by the references being cited. Further, there is nothing to indicate that anyone, not relying on hindsight, would, from the three references cited, arrive at the invention set forth in appellant‟s claims 6 and 17.” (App. Br. 13.) We are not persuaded. Burgert discloses: “This array, coupled with a flexible connector we have designed, should also reduce the occurrence of infection and tissue damage at the site of the measurement. This new connector system should also facilitate the surgical implantation of the array.” (FF 21.) In view of this teaching, the Examiner concludes: It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the IMD as taught by the modified Fischer, . . . with an array of neuro- needles attached to an electrical conductor and a flex connector containing the electrical conductor . . . as taught by Burgert, . . . to provide . . . a sensor array that reduces the occurrence of infection and tissue damage at the site of measurement and facilitates the surgical implantation of the array. (Ans. 17-18.) Appellant has not adequately explained why this conclusion is in error. Conclusion The evidence supports the Examiner‟s conclusion that Fischer, Sun, and Burgert suggest claim 6. We therefore affirm the obviousness rejection of claim 6 over Fischer in view of Sun and Burgert. Claims 5, 16, and 17 are not separately argued and therefore fall with claim 6. 37 C.F.R. § 41.37(c)(1)(vii). Appeal 2011-009420 Application 11/173,863 17 IV With regard to the obviousness rejection of claims 1, 3-6, and 13-17 over Burgert in view of Fischer and Sun, the Examiner concludes: It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the IMD as taught by Burgert, with . . . how the implant is constructed, such as being ceramic, with brazed and metal interface rings, . . . to provide the predictable results of a secure, hermetically sealed housing allowing for sensing/stimulating of the body and to provide a noble metal antenna, such as silver, on the exterior of the ceramic case to provide the predictable results of allowing the system to operate with enhanced data bit rates and low error rates over a long distance and to minimize power consumption. (Ans. 12.) Appellant argues that the “reshuffling of the same three references does not rise to a specific rejection of the cited claims absent a discussion of the elements” (App. Br. 14). However, having detected no error in this combination of references, we affirm the obviousness rejection of claims 1 and 13 over Burgert in view of Fischer and Sun. Claims 3-6 and 14-17 are not separately argued and therefore fall with claims 1 and 13. 37 C.F.R. § 41.37(c)(1)(vii). TIME PERIOD FOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
