NAZARETH, GREGORY A. BOSER, AND LORRAINE R. GAUNT 1 Appeal2017-008169 Application 14/521,958 Technology Center 3700 Before RICHARD M. LEBOVITZ, RICHARD J. SMITH, and JOHN E. SCHNEIDER, Administrative Patent Judges. LEBOVITZ, Administrative Patent Judge. DECISION ON APPEAL This appeal involves claims directed to implantable electrode lead for electrical stimulation of a body. The Examiner rejected the claims as anticipated under 35 U.S.C. § 102 and as failing to comply with the enablement requirement under 35 U.S.C. § 112. Appellants appeal the rejection pursuant to 35 U.S.C. § 134. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm-in-part. 1 The Appeal Brief ("Appeal Br.") 2 lists Medtronic, Inc. of Minneapolis, Minnesota, the assignee of record, and Medtronic plc of Dublin, Ireland, the ultimate parent entity of Medtronic, Inc. as the real parties in interest. Appeal2017-008169 Application 14/521,958 STATEMENT OF THE CASE The claims stand rejected by the Examiner as follows: Claims 6-15 and 24--31 under 35 U.S.C. § 112(a) for lack of enablement. Ans. 2. Claims 1-15 and 21-31 under 35 U.S.C. § 102(a)(l) based upon a public use or sale or other public availability of the invention. ENABLEMENT REJECTION Claims 6-15 and 24--31 stand rejected by the Examiner under 3 5 U.S.C. § 112(a). The Examiner found that Specification, while being enabling for a platinum-iridium cladding, does not reasonably provide enablement for employing Anomet, Inc. or for cladding in the 1-3 micron range. 2 Ans. 2. Claims 6 and 11 are independent claims. Claim 6 is illustrative of the rejected claims and reads as follows: 6. A system of producing an implantable electrode lead for electrical stimulation of a body of the type comprising an elongated insulative lead body, a conductor within the lead body and an electrode coupled to the conductor, comprising: employing Anomet, Inc to apply a platinum-iridium cladding to a tantalum core to produce an electrode wire in which the cladding forms an exposed surface of the electrode having a maximum thickness of less than three microns; and means for coiling the wire to form the electrode. Independent claim 11 is also a method claim and comprises the same step of "employing Anomet, Inc" as recited in claim 1. 2 Claim 1 also has the limitation of a cladding "having a maximum thickness of less than three microns," but was not rejected for lack of enablement. Claim 1 does not recite the step of "employing Anomet Inc." 2 Appeal2017-008169 Application 14/521,958 According to the Specification, "Anomet, Inc" is a company located in Shrewsbury, Massachusetts. Spec. 3:24--25. The Specification states: The invention is practiced employing a cladding technique provided by Anomet, Inc. Shrewsbury, MA (www.anometproducts.com) to fabricate the wires used to form these electrodes. Unlike the current traditional DPT approach, the inventors understand that Anomet wraps a foil around a core to form the cladding, extruding the clad core within in a nickel/stainless steel outer layer and then etching off the outer layer and drawing the cladded core to finished size. This process as applied to a melt quality tantalum core wire is particularly beneficial in the context of a coiled wire defibrillation electrode as in the present invention. The resultant clad wires can be obtained from Anomet, Inc. Spec. 3 :24--Spec. 4:2. The rejected claims require Anomet, Inc to be "employed" to produce the electrode wire. As we understand the claims, the term "employed" means that Anomet is used to make the electrode wire and that therefore the wire is obtained from Anomet, Inc. The Examiner found that the Specification does not describe or provide guidance on how the wire is produced, but relies entirely on Anomet, Inc. for its production. Ans. 2-3. Appellants do not dispute the Examiner's finding, but rather assert that "Because this component is commercially available, it is sufficient under Section 112 to identify the component and indicate where it may be purchased, i.e., from Anomet, Inc." Appeal Br. 4. Appellants contend that You don't have to know how to apply the coating to practice the claimed inventions. You just need to know about Anomet. Employing Anomet to coat the wire is simple. You ask them to do so and pay them to do it. In other words, you buy it from Anomet. One of skill in the art is presumed to know how to buy components from vendors. 3 Appeal2017-008169 Application 14/521,958 Appeal Br. 4. The step of "employing Anomet" means using the company. Anomet is a company, not a process. The company uses the process. The person practicing the invention as claimed doesn't need to know how the coating is applied any more than an electrical engineer needs to know how to make a transistor in order to use one in a circuit. Reply Br. 5. Appellants' argument does not persuade us that the Examiner erred in rejecting the claims for lack of enablement. It is undisputed that the rejected claims require one of ordinary skill in the art to obtain electrode wire from Anomet in order to practice the claimed method. For a Specification to be enabling under 35 U.S.C. § 112, a material necessary to practice the claim must be available to the public for the pendency of the patent. In re Lundak, 773 F.2d 1216 (Fed. Circ. 1985); In reArgoudelis, 434 F.2d 1390 (CCPA 1970), John E. Schneider, Microorganisms and the Patent Office: To Deposit or Not to Deposit, That is the Question. 52 Fordham L. Rev. 592, 595-596 (1984). Thus, in Lundak, where the invention was found to depend on the use of a microorganism, and the microorganism was not known or readily available, a deposit of the microorganism in a publically accessible depository was considered necessary to meet the enablement requirement to ensure that the claims were enabled for the life of the patent. In this case, where the electrode wire provided by Anomet is necessary to carry out the claimed method, the availability of the wire must be ensured for the patent's pendency to meet the enablement requirement under 35 U.S.C. § 112. Because the claim explicitly names Anomet, Inc. in the claim as the wire's sole source, and the Specification lacks a description of how the wire 4 Appeal2017-008169 Application 14/521,958 is made, the Examiner had a reasonable basis to question the enablement of the rejected claims. In re Wright, 999 F.2d 1557, 1562 (Fed. Cir. 1993). In response, Appellants assert that the wire is commercially available from Anomet, Inc., but do not provide any assurances that Anomet, Inc., which is explicitly recited in the claim as the source of the electrode wire, will make the claimed electrode commercially for the patent's pendency, should a patent on the claims issue. Thus, even if the disclosure is initially enabling, there is no assurance that it will be enabled for the patent's pendency. See In re Metcalfe, 410 F.2d 1378, 1382 (CCPA 1969). Consequently, we affirm the enablement rejection of claims 6 and 11, and dependent claims 7-10 and 24--31. ANTICIPATION REJECTION Independent claim 1 is directed to an implantable electrode comprising: 1) an elongated insulative body; 2) a conductor in the body; and 3) an electrode coupled to the conductor comprising a coiled wire comprising "a platinum-iridium cladding directly overlaying an un- smoothed melt quality tantalum core." Independent claim 5 is directed to a method of making an implantable electrode with the same three elements of the implantable electrode of claim 1. Independent claims 5, 6, and 11 are directed to methods of producing the electrode lead having the same limitations. The Examiner rejected that the claims based on the "public availability of the invention" because the Specification "disclose[ s] the invention is practiced employing a cladding technique provided by Anomet, Inc. to fabricate the wires used to form the electrodes. The coiled wire 5 Appeal2017-008169 Application 14/521,958 defibrillation electrode of the present invention is stated on page 4 of the specification to be obtained from Anomet, Inc." Ans. 3. The Specification discloses that Anomet makes the electrode wire. Spec. 3. The Specification also discloses that the wire "is particularly beneficial in the context of a coiled wire defibrillation electrode as in the present invention. The resultant clad wires can be obtained from Anomet, Inc." Id. at 3 :30-4:2. The Specification states that "the resultant composite wire displays improved rotary bend fatigue performance" and describes aspects of the coiling process, indicating that Anomet, Inc. does not provide the coiled wire itself (id. at 4: 16-27), despite the Examiner's conclusion to the contrary (Ans. 3). However, even if Anomet, Inc. sells the coiled wire of element (3) of claims 1, 5, 6, and 11, the Examiner did not identify disclosure in the Specification that Anomet, Inc. provides (1) the elongated insulative body or (2) the conductor within in the lead body as required by all of the rejected claims. A claim is anticipated under 35 U.S.C. § 102 when a publication "disclose[ s] all elements of the claim within the four comers of the document" and "arranged as in the claim." Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1369 (Fed. Cir. 2008). In this case, the Examiner did not provide evidence that Anomet provides all the elements of claims 1, 5, 6, and 11, particularly 1) an elongated insulative body; and 2) a conductor in the lead body. Consequently, the anticipation rejection of claims 1, 5, 6, and 11, and of dependent claims 2--4, 7-10, 12-15, and 21-31, is reversed. 6 Appeal2017-008169 Application 14/521,958 TIME PERIOD No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv).
