`
`INTRODUCTION
`
`A. Background
`
`Heart Failure Technologies, LLC (“Petitioner”) filed a petition to institute an
`
`inter partes review of claims 1 and 10 of U.S. Patent 7,582,051 (the “ ’051
`
`patent”). Paper 4 (“Pet.”). Patent Owner CardioKinetix, Inc. timely filed a
`
`preliminary response. Paper 10 (“Prelim. Resp.”). The standard for instituting an
`
`inter partes review is set forth in 35 U.S.C. § 314(a), which provides as follows:
`
`THRESHOLD.—The Director may not authorize an inter
`partes review to be instituted unless the Director
`determines that the information presented in the petition
`filed under section 311 and any response filed under
`section 313 shows that there is a reasonable likelihood
`that the petitioner would prevail with respect to at least 1
`of the claims challenged in the petition.
`
`Petitioner presents the following grounds of unpatentability (Pet. 3):

`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`We determine that the record before us does not demonstrate that there is a
`
`reasonable likelihood that Petitioner would prevail with respect to at least one
`
`challenged claim. We consequently deny the petition and decline to institute an
`
`inter partes review of the ’051 patent.
`
`B. The Invention
`
`The ’051 patent (Ex. 1001) is entitled “Peripheral Seal for a Ventricular
`
`Partitioning Device,” and relates generally to a device used to divide a heart
`
`chamber into a productive portion and a non-productive portion. Abstr. The
`
`device finds particular application in patients having hearts with weakened walls or
`
`enlarged chambers, due to various forms of congestive heart failure. Col. 2,
`
`ll. 38-45. Partitioning relieves stress on the weakened wall tissue and reduces
`
`chamber volume, thereby improving the heart function measurement known as
`
`ejection fraction. Id.
`
`Figure 1 of the ’051 patent is reproduced below:
`
`Figure 1 illustrates partitioning device 10. The device includes an
`
`expandable frame 13 formed from ribs 14 that extend from hub 12 to free proximal
`
`ends 16. Col. 5, ll. 45-51. Partitioning membrane 11 is secured to the frame and is
`
`unfurled when the free proximal ends expand radially. Id. at ll. 53-54. When
`
`
`

`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`unfurled, the membrane presents a pressure receiving surface 17 (the undersurface,
`
`not indicated in Fig. 1). Id. at ll. 53-55. The membrane has a peripheral edge 18
`
`(also not indicated in Fig. 1) that may have serrations. Id. at ll. 57-58. A
`
`continuous expansive strand 19 extends around the periphery of the membrane on
`
`the undersurface. Id. at 59-60. The strand applies pressure to the membrane to
`
`seal the periphery to the wall of the ventricular chamber. Id. at 60-63. The strand
`
`is biased outwardly and ensures that folds or wrinkles are not formed when the
`
`device is expanded for deployment. Col. 3, l. 66 to col. 4, l. 2.
`
`Claim 1 illustrates the claimed subject matter and is reproduced below:
`
`1. A device for treating a patient by partitioning a
`chamber of the patient's heart into a primary productive
`portion and a secondary non-productive portion, the
`device comprising:
`
`an expandable frame formed of a plurality of ribs
`having distal ends secured to a central hub and
`free, outwardly flared, proximal ends,
`
`a pressure receiving membrane formed at least in part
`of flexible material, the membrane forming a
`recess in an expanded, deployed configuration,
`wherein the membrane comprises a loose and
`flexible peripheral region configured to seal to a
`ventricular wall surface to partition the ventricle
`and create the secondary non-productive portion,
`wherein the flexible peripheral region of the
`membrane comprises notched serrations; and
`
`an outwardly biased member which is secured to the
`membrane at a position that is radially inward from
`the loose peripheral region of the membrane,
`wherein
`the outwardly biased member
`is
`configured to stiffen at least a portion of the
`membrane so as to reduce wrinkling of the
`membrane so that the peripheral region of the
`

`
`
`membrane may seal against a ventricular wall
`surface defining in part the heart chamber.
`
`C. Claim Construction
`
`Consistent with the statute and the legislative history of the AIA, the Board
`
`will interpret claims of an unexpired patent using the broadest reasonable
`
`construction in light of the specification of the patent. See Office Patent Trial
`
`Practice Guide, 77 Fed. Reg. 48756, 48766 (Aug. 14, 2012); 37 CFR
`
`§ 42.100(b). Petitioner does not propose any constructions deviating from this
`
`standard. Pet. 5. Patent Owner directs no comments to claim construction in the
`
`Preliminary Response.
`
`II. ANALYSIS
`
`A. Overview
`
`Petitioner contends that claims 1 and 10 are (1) obvious over Murphy and
`
`Khairkhahan in combination with either Lane or Salahieh, and (2) obvious over
`
`Lesh, Khairkhahan, and Nikolic, also in combination with either Lane or Salahieh.
`
`Pet. 3; see chart supra.
`
`B. Obviousness of claims 1 and 10 over Murphy, Khairkhahan, and Lane
`
`Petitioner’s presentation of this challenge appears at pages 5-17 of the
`
`petition.
`
`Murphy describes a device and method for reshaping a ventricle that has
`
`non-viable tissue in its wall. Col. 6, l. 65–col. 7, l. 7. The ventricle is reshaped by
`
`“imbricating” it, meaning that edges of the ventricle wall having non-viable tissue
`
`between them are brought together so that the non-viable tissue is excluded. Id.
`
`Figure 2b of Murphy is reproduced below:
`
` 5
`
`

`Universal Remote Control v. Universal Electronics, Trial No. IPR2014-01109
`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`
`
`Figure 2b shows a shaping device 210, which has a main wire 212 running
`
`through its center and a series of back ribs 214a-d coupled to the main wire at
`
`collar 216. Col. 4, ll. 45-50. A patch (not shown) may be coupled to the shaping
`
`device. Col. 6, ll. 31-33. The patch is sized to cover the non-viable tissue that is to
`
`be excluded, col. 8, ll. 6-11, and is positioned to align with that tissue. Col. 10,
`
`ll. 44-47. The ventricle wall is reshaped by pressing it against the shaping device
`
`using a molding instrument. Col. 7, ll. 8-13. A clasping instrument applies
`
`implements (such as sutures, staples, or clips) to the ventricle wall along the edges
`
`of the portion to be excluded. Id. at ll. 13-21. When the implements are closed,
`
`the ventricle wall will have been pulled over the shaping device and will maintain
`
`its shape. Id. at ll. 25-28.
`
`Khairkhahan describes devices and methods for occluding the left atrial
`
`appendage, a portion of the heart in which blood may clot when it stagnates there
`
`during atrial fibrillation. Khairkhahan ¶ [0003].
`
`Figures 3 and 4 of Khairkhahan are reproduced below:
`

`Universal Remote Control v. Universal Electronics, Trial No. IPR2014-01109
`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`
`
`
`
`Figures 3 and 4 show an occluding device 10, which has an occlusion
`
`member 11 and stabilizing member 194. Id. at ¶ [0062]. The occlusion member
`
`includes a mesh-like barrier 15 secured to a frame that is formed by an array of
`
`radially outwardly-extending spokes 17. Id. at ¶¶ [0044], [0047], [0048]. The
`
`spokes extend from hub 16. Id. at ¶ [0046]. Each spoke has a proximal zone 212
`
`with an “enhanced degree of flexibility” to assist engagement of the occlusion
`
`member with the wall of the left atrial appendage. Id. at ¶ [0064]. Each spoke
`
`terminates with a proximal point 214, which may be either embedded in the barrier
`
`or extend beyond it to assist further with engagement. Id. at ¶ [0065].
`
`Lane describes replacement heart valve assemblies. Abstr. The assembly
`
`includes a prosthesis, which serves as an interface between the surrounding tissue
`
`and the replacement valve. Col. 1, ll. 60-67. The prosthesis includes an annular
`
`ring that is implantable in the surrounding tissue and a sewing cuff to which the
`
`replacement valve is stitched. Id.
`
`Detail from Figure 17A is reproduced below:

`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`
`
`The detail from Figure 17A shows a heart valve assembly, which includes a
`
`prosthesis (gasket member 312) and a valve (crown 314). Col. 24, ll. 19-21. The
`
`gasket member includes annular ring 318, flexible baleen element 330, sewing cuff
`
`320, and covering fabric 336. Id. at ll. 22-26. The baleen element has a base 380
`
`from which fingers 382 extend. Col. 25, ll. 57-59. The fingers may be biased to
`
`extend outwardly. Id. at 65-66. When they do so, they press the fabric covering
`
`against the surrounding tissue to enhance the seal formed by the gasket member.
`
`Col. 27, l. 64 to col. 28, l. 2. The fingers may have uniform or varying lengths,
`
`may define undulations or lobes, or may vary in thickness. Col. 26, ll. 4-15;
`
`Figs. 20A-D.
`
`Petitioner argues that Murphy and Khairkhahan disclose all limitations of
`
`each of claims 1 and 10 except the requirement that the peripheral region of the
`
`membrane have “notched serrations.” Pet. 6-7. In particular, Petitioner contends
`
` 8
`
`
`
`
`
`Universal Electronics Exhibit 2009, Page 8
`Universal Remote Control v. Universal Electronics, Trial No. IPR2014-01109
`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`that Khairkhahan discloses the claimed outwardly biased member. Pet. 9, 13.
`
`Petitioner argues that Lane discloses the notched serrations. Id. at 7-8. Petitioner
`
`asserts that a person having ordinary skill in the art would have had reason to
`
`combine the relevant teachings of Murphy, Khairkhahan, and Lane to reach the
`
`claimed subject matter because these references “are related to the repair of a
`
`human heart.” Pet. 5; see also Pet. 9.
`
`Patent Owner argues, among other things, that the petition fails to explain
`
`how Khairkhahan discloses the outwardly biased member. Prelim. Resp. 10,
`
`37-39. Patent Owner also argues that Petitioner has made no more than a bare
`
`assertion of obviousness, without any explanation of how the teachings of the
`
`references would be arranged or combined or why a person of ordinary skill would
`
`have made the combination. Prelim. Resp. 8, 39-41.
`
`We agree with Patent Owner on both points. The fact that Murphy,
`
`Khairkhahan, and Lane all concern human heart repair is not in itself sufficient
`
`rationale for making the combination. Many heart repair devices exist. That fact
`
`alone would not make it obvious to combine their features. Petitioner must show
`
`some reason why a person of ordinary skill in the art would have thought to
`
`combine particular available elements of knowledge, as evidenced by the prior art,
`
`to reach the claimed invention. See KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398,
`
`418 (2007). This, the Petitioner has not done. That the references relied upon all
`
`relate to human heart repair does not amount to “some articulated reasoning with
`
`some rational underpinning to support the legal conclusion of obviousness.” See
`
`id. (internal quotations omitted).
`
`Moreover, we agree further with Patent Owner that Petitioner has not
`
`explained satisfactorily how the references, when combined, meet the “outwardly
`
`biased member” limitation. Petitioner relies on Khairkhahan alone for disclosure
`
` 9
`
`
`
`
`
`Universal Electronics Exhibit 2009, Page 9
`Universal Remote Control v. Universal Electronics, Trial No. IPR2014-01109
`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`of this limitation, but simply reproduces Khairkhahan’s Figure 3 and paraphrases
`
`two paragraphs of Khairkhahan’s specification. See, e.g., Pet. 13. Petitioner does
`
`not identify what structure shown or described in these excerpts meets the
`
`limitation. No structure shown in the Khairkhahan excerpts Petitioner relies on is
`
`plainly an “outwardly biased member” as recited in claims 1 and 10. The petition
`
`thus does not make clear the relevance of the cited disclosure to the claim
`
`limitation at issue. It was Petitioner’s burden to demonstrate how the prior art
`
`would have made obvious the claimed subject matter as a whole, and Petitioner has
`
`not done this. Petitioner’s presentation is incomplete in this respect and, therefore,
`
`insufficient to demonstrate a reasonable likelihood of prevailing on this
`
`obviousness challenge.
`
`For these reasons, we determine that Petitioner has not demonstrated a
`
`reasonable likelihood that claims 1 and 10 are unpatentable over Murphy,
`
`Khairkhahan, and Lane.
`
`C. Obviousness of claims 1 and 10 over Murphy, Khairkhahan, and
`Salahieh
`
`Petitioner’s presentation of this challenge appears at pages 17-28 of the
`
`petition. This challenge, however, suffers from the same deficiencies discussed
`
`above. Petitioner offers the same inadequate rationale for combining the
`
`respective references: that they all relate to repair of the human heart. See Pet. 18.
`
`As discussed, this assertion is insufficient to support an obviousness challenge.
`
`See supra. Moreover, this challenge also relies on Khairkhahan for disclosing the
`
`“outwardly biased member” limitation, but Petitioner does not explain how the
`
`cited passages of Khairkhahan meet that limitation. See, e.g., Pet. 25.

`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`For these reasons, we determine that Petitioner has not demonstrated a
`
`reasonable likelihood of prevailing on its assertion that claims 1 and 10 are
`
`unpatentable over Murphy, Khairkhahan, and Salahieh.
`
`D. Obviousness of claims 1 and 10 over Lesh, Khairkhahan, Nikolic, and
`Lane
`
`Petitioner’s presentation of this challenge appears at pages 28-45 of the
`
`petition.
`
`Lesh, like Khairkhahan, describes devices and methods for occluding the left
`
`atrial appendage. Abstr. Figure 1 is reproduced below:
`
`
`
`Figure 1 of Lesh shows an occluding device 10 having occluding member 11
`
`and retention member 12. Col. 7, ll. 31-33. The occluding member is disc-shaped
`
`and is formed from a frame structure 14 of arms extending from hub 16 to outer
`
`rim 13. Id. at ll. 35-41. The outer rim may contain a radial hoop 21 that maintains
`
`the ring shape of the outer rim and facilitates its radial expansion. Id. at ll. 64-67.
`
`The outer rim seals against the surface of the left atrial appendage. Col. 8,
`
`ll. 60-62.
`
`
`
`

`Universal Remote Control v. Universal Electronics, Trial No. IPR2014-01109
`
`

`

`Case IPR2013-00183
`Patent 7,582,051
`
`
`This challenge suffers from the same deficiencies as the challenges
`
`discussed above. Petitioner offers the same inadequate rationale for combining the
`
`respective references: that they all relate to repair of the human heart. See Pet. 29.
`
`As discussed, this assertion is insufficient to support an obviousness challenge.
`
`See supra.
`
`Petitioner also does not persuade us that the cited references disclose the
`
`“outwardly biased member” limitation. Petitioner cites Khairkhahan and Lesh as
`
`each disclosing this limitation. See, e.g., Pet. 38-39. Petitioner excerpts from
`
`Khairkhahan the same portions as in the challenges discussed supra, and similarly
`
`gives no explanation as to how the cited passages meet the claim limitation.
`
`Petitioner also cites Figures 1-3 of Lesh and portions of the specification that
`
`describe the outer rim and the radial hoop. Id. Petitioner, however, does not
`
`explain how either of these structures satisfies the requirement that the outwardly
`
`biased member be “at a position that is radially inward” from the peripheral region
`
`of the membrane. As can be seen in Lesh’s Figure 1, and as can be inferred from
`
`its name, the outer rim is at the outermost edge of the occluding device. Petitioner
`
`has not explained how Lesh’s radially outermost position meets the claimed
`
`“position that is radially inward.”
`
`Thus, Petitioner has neither provided an adequate rationale for the
`
`combination of the cited references, nor shown that the references, when
`
`combined, disclose the claimed subject matter or otherwise would have made it
`
`obvious. For these reasons, we determine that Petitioner has not demonstrated a
`
`reasonable likelihood that claims 1 and 10 are unpatentable over Lesh,
`
`Khairkhahan, Nikolic, and Lane.

`
`
`E. Obviousness of claims 1 and 10 over Lesh, Khairkhahan, Nikolic, and
`Salahieh
`
`Petitioner’s presentation of this challenge appears at pages 45-59 of the
`
`petition. This challenge suffers from the same deficiencies discussed in section
`
`II.D, supra, for the challenge based on Lesh, Khairkhahan, Nikolic, and Lane.
`
`Petitioner offers the same inadequate rationale for combining the respective
`
`references as for the other challenges: that they all relate to repair of the human
`
`heart. See Pet. 45. This assertion is insufficient to support an obviousness
`
`challenge. Moreover, this challenge relies on Khairkhahan or Lesh for disclosing
`
`the “outwardly biased member” limitation, but Petitioner does not explain how the
`
`cited passages of Khairkhahan or Lesh meet that limitation. See, e.g., Pet. 54-55.
`
`For these reasons, we determine that Petitioner has not demonstrated a
`
`reasonable likelihood that claims 1 and 10 are unpatentable over Lesh,
`
`Khairkhahan, Nikolic, and Salahieh.
`
`III. SUMMARY
`
`Petitioner has not shown that there is a reasonable likelihood that it would
`
`prevail with respect to at least one of the claims challenged in the petition. The
`
`petition is therefore denied.
`
`IV. ORDER
`
`For the reasons given, it is
`
`
`
`ORDERED that the petition challenging the patentability of claims 1
`
`and 10 of Patent 7,582,051 is denied.
