`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`I.
`
`QUALIFICATIONS
`
`5. My resume is being provided with this Declaration. As indicated
`
`there, I have eight publications and I am a named inventor on over 130 patents for
`
`medical devices. I have extensive experience with surgical instruments, and
`
`surgical staplers in particular, which is the subject matter of the ’431 Patent.
`
`6.
`
`Specifically, I have been involved in the research and development,
`
`design, and manufacture of medical devices including surgical cutting and stapling
`
`devices since 1992, and am qualified to present the analysis provided in this
`
`declaration.
`
`7.
`
`I was employed in the Research and Development department as an
`
`engineer of Ethicon Endo-Surgery. I was the lead design engineer for endoscopic
`
`linear staplers/cutters. In this lead design engineer role, it was my responsibility to
`
`understand every aspect of these devices.
`
`8.
`
`One early patent of mine is U.S. Patent No. 5,465,895, entitled
`
`“Surgical Stapler Instrument,” and granted on November 14, 1995. The ’895
`
`Patent states: “The present invention relates in general to surgical stapler
`
`instruments which are capable of applying lines of staples to tissue while cutting
`
`the tissue between those staple lines and, more particularly, to improvements
`
`relating to stapler instruments and improvements in processes for forming various
`
`components of such stapler instruments.” ’895 Patent, 1:5-10. My ’895 Patent
`
`5
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`specifically discloses jaws that open and close and a gear-driven knife to cut
`
`stapled tissue. I am thus generally familiar with such mechanisms for surgical
`
`instruments.
`
`9.
`
`Beginning in 1998, I have been a consultant for medical device
`
`companies and law firms. I have consulted in the areas of conceptual design,
`
`prototyping, and turnkey product design.
`
`10.
`
`In addition, I have worked on a variety of surgical products for use in
`
`a wide range of surgical procedures including female reproductive system, female
`
`incontinence, female pelvic floor dysfunction, lung volume reduction, colon,
`
`GERD, bariatrics, CABG, heart valve repair, hernia, general surgical procedures,
`
`and surgical stapling, which is the general subject matter of the patent-at-issue.
`
`11. As part of my consulting practice, I have also acted as a non-testifying
`
`expert in a patent litigation case in the area of medical devices.
`
`12.
`
`I have not testified as an expert witness at trial or by deposition during
`
`the previous four years.
`
`13.
`
`I am being compensated at my usual and customary rate of $200/hour
`
`for my work on this case, plus reimbursement for actual expenses. My
`
`compensation is not contingent upon the conclusions I reach, the outcome of this
`
`inter partes review, or any litigation involving the ’431 Patent.
`

`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`II. MY UNDERSTANDING OF CLAIM CONSTRUCTION
`
`14.
`
`I understand that claim terms are read in light of the patent’s
`
`specification and file history as understood by a person of ordinary skill in the art
`
`at the time of the purported invention. I further understand that in an inter partes
`
`review proceeding of an unexpired patent, such as the ’431 Patent, the claim terms
`
`are to be given their broadest reasonable interpretation (“BRI”) consistent with the
`
`specification. I understand that constructions under the BRI standard should be at
`
`least as broad as constructions under the plain and ordinary meaning standard used
`
`in district court litigation.
`
`III. LEGAL STANDARDS
`
`15.
`
`I am not a lawyer and do not provide any legal opinions. Although I
`
`am not a lawyer, I have been advised that certain legal standards are to be applied
`
`by technical experts in forming opinions regarding meaning and validity of patent
`
`claims.
`
`16. As part of this inquiry, I have been asked to consider the level of
`
`ordinary skill in the field that someone would have had at the time the claimed
`
`invention was made. In deciding the level of ordinary skill, I considered the
`
`following:
`
`
`
`
`
`the levels of education and experience of persons working in the field;
`
`the types of problems encountered in the field; and
`
`7
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`
`
`the sophistication of the technology.
`
`17.
`
`I understand that a claim is invalid if a single prior art reference
`
`(including information that the single prior art reference specifically incorporates
`
`by reference) discloses a claimed invention (the invention thus lacks novelty) or if
`
`the claim would have been obvious to one of ordinary skill in the art at the time of
`
`the purported invention based on the teachings of one or more prior art references.
`
`18.
`
`I understand that the time of the purported invention is the earliest
`
`possible effective filing date of the application that discloses the claimed subject
`
`matter.
`
`19.
`
`I am informed that a claim can be invalid based on anticipation if each
`
`limitation of the claim is found in the four corners of a single prior art reference
`
`(including any incorporated material), either explicitly or inherently.
`
`20.
`
`I am informed that a claim can be invalid based on obviousness in
`
`light of a single prior art reference alone (based on general knowledge in the art),
`
`or based upon a combination of prior art references, where there is some reason
`
`one of ordinary skill in the art would make the combination.
`
`21.
`
`I am informed that when evaluating whether an invention would have
`
`been obvious, the question is whether the differences between the subject matter
`
`sought to be patented and the prior art are such that the subject matter as a whole
`
`would have been obvious to a person of ordinary skill in the art at the time the
`
`8
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`purported invention was made. In other words, the question is not whether a single
`
`element “would have been obvious” but whether the claim as a whole would have
`
`been obvious given what was known in the prior art.
`
`22.
`
`I understand that an obviousness analysis should (1) identify the
`
`particular references that, singly or in combination, make the patent obvious; (2)
`
`specifically identify which elements of the patent claim appear in each of the
`
`asserted references; and (3) explain a motivation, teaching, need or market pressure
`
`that would have inspired a person of ordinary skill in the art to combine prior art
`
`references to solve a problem.
`
`23.
`
`I understand that certain objective indicia should be considered, if
`
`available, regarding whether a patent claim would have been obvious or
`
`nonobvious. Such indicia include: commercial success of products covered by the
`
`patent claims; a long-felt need for the invention; failed attempts by others to make
`
`the invention; copying of the invention by others in the field; unexpected results
`
`achieved by the invention as compared to the closest prior art; praise of the
`
`invention by the infringer or others in the field; the taking of licenses under the
`
`patent by others; expressions of surprise by experts and those skilled in the art at
`
`the making of the invention; and the patentee proceeded contrary to the accepted
`
`wisdom of the prior art. I am not aware of any such indicia that would be pertinent
`
`to the challenged claims.
`
`9
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`24. Furthermore, I understand that the United Sates Supreme Court in its
`
`KSR vs. Teleflex decision ruled that “if a technique has been used to improve one
`
`device, and a person of ordinary skill in the art would have recognized that it
`
`would improve similar devices in the same way, using the technique is obvious
`
`unless its actual application is beyond that person’s skill.”
`
`IV. LEVEL OF ORDINARY SKILL IN THE ART
`
`25. A person of ordinary skill in the art at the time of the alleged
`
`invention would have had the equivalent of a Bachelor’s degree or higher in
`
`mechanical engineering with at least 3 years working experience in the design of
`
`comparable surgical devices. Additional education in a relevant field, such as
`
`mechanical engineering or robotics (to the extent pertinent), or industry experience
`
`may compensate for a deficit in one of the other aspects of the requirements stated
`
`above.
`
`26.
`
`I am a person of at least ordinary skill in the art, and was such a
`
`person as of the priority date of the ’431 Patent, which I am informed by counsel
`
`that, for purposes of this petition, is May 27, 2011. I was also a person of at least
`
`ordinary skill in the art as of June 4, 2007, the filing date of the grandparent ’380
`
`patent.
`
`V. OVERVIEW OF THE ’431 PATENT
`
`27. The ’431 Patent’s specification generally has two parts. It first
`
`10
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`discusses a hand-held embodiment at length, and this material generally comes
`
`from the original application filed in 2007. In 2011, the applicant filed a
`
`“continuation-in-part” application that added new material related to a robotic
`
`embodiment, essentially adapting the handheld surgical instrument to work with
`
`then-existing surgical robot systems, such as those made by Intuitive Surgical.
`
`Each of the claims of the ’431 Patent concern the robotic embodiments. The
`
`claims also require a “transmission arrangement” that allows rotary motion to be
`
`selectively applied to at least two different functions, such as staple firing and
`
`articulation. Some claims require the transmission to operate with a shifter gear
`
`and shifter shaft. However, Ethicon did not invent shiftable transmissions or
`
`surgical robots, and the ’431 Patent claims simply combine these two typical and
`
`conventional components—and in a manner that already existed in the prior art.
`
`VI. PROSECUTION HISTORY OF THE ’431 PATENT
`
`28. During prosecution of the ’431 Patent, the Examiner rejected many of
`
`Applicant’s original claims as anticipated by U.S. Patent Application No.
`
`2002/0072736, which is assigned to Petitioner Intuitive Surgical and discloses the
`
`same robotic surgical system as Tierney. IS1002 (File History), 373-77. The
`
`Examiner also rejected two of Applicant’s original claims because they would have
`
`been obvious over the ’736 application in view of U.S. Patent No. 6,981,628. Id.,
`
`377-79.
`
`11
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`29.
`
`In response to this rejection, the applicant amended the rejected
`
`claims to require “application of separate control motions to different portions of
`
`an end effector from a single rotatable driven element of the tool drive assembly.”
`
`IS1002 (File History), 345, 354-55 (emphasis in original) (also arguing that “a
`
`plurality of driven elements [] are required to control the end effector elements
`
`112a, 112b” in the tool drive assembly of the robotic system disclosed in the ’736
`
`application). A notice of allowance subsequently issued. Id., 168. As explained
`
`below, however, application of separate control motions to different portions of an
`
`end effector from a single rotatable driven element of a tool drive assembly was
`
`not new, and is disclosed by Whitman.
`
`VII. THE ’431 PATENT’S PRIORITY DATE
`
`30. The ’431 Patent claims priority as a continuation of U.S. App. No.
`
`13/118,223 (the “’223 Application”), filed on May 27, 2011, now U.S. Patent No.
`
`8,931,682 (IS1009, “Timm Patent”), which is a continuation-in-part of U.S. App.
`
`No. 13/020,053 (the “’053 Application”), filed on Feb. 3, 2011 and issued as U.S.
`
`Patent No. 8,196,796 (IS1008, “Shelton Patent”), which is a continuation of U.S.
`
`App. No. 11/810,015 (the “’015 Application”), filed on June 4, 2007 and issued as
`
`U.S. Patent No. 7,905,380 (the “’380 Patent”). I have not been asked to consider,
`
`and so have not considered, whether the parent ’223 Application provides written
`
`description support for the ’431 Patent. I have, however, considered whether the
`
`12
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`grandparent Shelton Patent (IS008) and great grandparent ’380 Patent provide
`
`written description support for the challenged claims of the ’431 Patent, and I have
`
`concluded that they do not. In particular, each challenged claim of the ’431 Patent
`
`claims a “robotic system.”
`
`31.
`
`I reviewed the Shelton Patent and the ’380 Patent and saw no
`
`disclosure of a “robotic system,” as required by the claims. Rather, they discuss –
`
`and thus one of ordinary skill in the art would understand them to disclose – only a
`
`handheld endoscopic surgical instrument. Accordingly, a person of skill in the art
`
`would not understand the inventors to have possession of the alleged invention of
`
`the challenged claims prior to the filing of the 2011 application. My
`
`understanding, therefore, is that the ’431 Patent has a priority date no earlier than
`
`May 27, 2011.
`
`32. Again, I offer no opinion as to whether the parent ’223 Application
`
`provides written description support for any claim of the ’431 Patent, and
`
`understand that the burden to show such a disclosure in an alleged priority
`
`document falls on the patentee.
`
`VIII. INTERPRETATION OF THE ’431 PATENT CLAIMS
`
`33.
`
`I apply the broadest reasonable interpretation of the terms of the
`
`challenged claims of the ’431 Patent. Under BRI, I do not believe the claims to
`
`require clarification beyond the plain meaning of those terms. I am informed that
`
`13
`
`

`

`in District Court, different legal standards apply that may narrow the claims in a
`
`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`way not applicable under BRI.
`
`IX. OVERVIEW OF THE PRIOR ART
`
`A.
`
`Shelton Application
`
`34. The following annotated figures from the Shelton Application
`
`illustrate a typical prior art motorized surgical stapler:
`
`
`
`14
`
`Elongated Shaft
`Assembly 56
`
`Shifter
`handles 164
`
`Trigger 54
`
`End Effector 58
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`
`
`Shelton Application, FIGs. 1, 8.
`
`35. This prior art surgical stapler has a knife that cuts the tissue between
`
`two rows of staples. Id., FIG. 2 (element 99). As is typical, there is a transmission
`
`between the motor and the end effector to transmit the rotary motion (and may
`
`often, if desired, convert high motor speed into a lower speed / higher torque
`
`motion). The transmission also uses a shifter to reverse the direction of the knife
`
`(controlled by shifter handles 164). Id., ¶¶56-57, 63-65, FIG. 5. The Shelton
`
`Application uses a sliding transmission in which movement of the shifter handles
`
`causes “forward” and “reversing” gears to slide into and out of engagement with
`
`15
`
`Transmission
`
`End
`effector
`
`Trigger 54
`
`Shifter
`Handles
`164
`
`

`

`bevel gear 114. Id. Below is highlighted the shifter shaft with a forward gear 136
`
`and reversing gear 134 that are selectively engaged with the bevel gear 114.
`
`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`
`
`Id., FIG. 5.
`
`36. When the shifter handles 164 are moved to the downward position,
`
`the knife is driven by the “forward gear” and thus moves forward to cut tissue, and
`
`when the shifter handles 164 are in the upward position, the knife is driven by the
`
`“reversing gear” and thus reverses direction. Id., ¶65.
`
`B.
`
`Tierney
`
`37. The ’431 Patent incorporates by reference, and largely copies, the
`
`prior art drive interfaces for surgical robots designed by Petitioner Intuitive
`
`Surgical and disclosed in its prior art patents, including Tierney:
`
`Over the years a variety of minimally invasive robotic (or
`
`“telesurgical”) systems have been developed to increase surgical
`
`16
`
`

`

`Attorney Docket No. 11030-0049IP7
`IPR of U.S. Patent No. 8,616,431
`
`dexterity as well as to permit a surgeon to operate on a patient in
`
`an intuitive manner. Many of such systems are disclosed in the
`
`following U.S. patents which are each herein incorporated by
`
`reference in their respective entirety: [such as]. . . U.S. Pat. No.
`
`7,524,320, entitled “Mechanical Actuator Interface System For
`
`Robotic Surgical Tools” [(“Tierney”)] . . . .
`
`’431 Patent, 26:11-34. Not surprisingly, the surgical robot of the ’431 Patent bears
`
`a striking resemblance to Tierney:

`C. Whitman
`
`38.
`
`In 2009, Whitman disclosed a surgical instrument with a shiftable
`
`transmission that permits a single drive element to be selectively coupled to one of
`
`multiple drivers to control four different functions of a surgical tool. FIG. 3B of
`
`Whitman, for example, depicts an embodiment with “function selector block 609”
`
`that can select among four different functions, such as “[1] rotation, [2]
`
`19
`
`

`

`
`articulation, [3] opening/closing of the jaws relative to each other, and [4] firing
`
`the cutting and/or stapling mechanism.” Whitman, ¶114. Each of these functions
`
`is selectively driven by “function shaft 611” depending on the placement of
`
`“function selector block 609.” Id., ¶¶92-94, 142-74, 241-44.
`
`
`
`
`
`Id., FIG. 3B. When function selector block is in the first position (3001 in FIG.
`
`3B), function shaft 611 is coupled to rotating tube 677 such that rotation of the
`
`function shaft 611 will cause the end effector to rotate. Id., ¶¶142-45. If the
`
`function selector block is moved to the second position (3002 in FIG. 3B), then
`
`function shaft 611 is coupled to articulation gear shaft 693 such that rotation of the
`
`function shaft 611 will cause the end effector to articulate. Id., ¶¶147-54.

`
`D. Zemlock
`
`39. Zemlock discloses a powered surgical instrument with a “[s]hift motor
`
`220 [that] is configured to selectively move [a] drive gear 200 between a plurality
`
`of positions.” Zemlock, ¶48, FIGs. 5-7, 9-11, 14. The drive gear is mounted on
`
`the shifter shaft and corresponds to the recited “driven gear” of claim 7. In the
`
`’431 Patent, the “driven” gear is “driven” by the shaft rotation, and drives gears
`
`associated with each function depending on the driven gear’s position. Zemlock’s
`
`transmission works in the same way. “[D]rive gear 200” is driven by the shaft, and
`
`drives gears associated with each function depending on drive gear 200’s axial
`
`position. Id.
`
`40. The drive gear is moved axially by the shifter shaft to mesh with
`
`different gears arranged axially adjacent the shifter shaft. Each of the gears that
`
`the drive gear can mesh with provides a different function (e.g., articulation or
`
`rotation). FIG. 10 illustrates the transmission with the “driven gear” (drive gear
`
`200) in the third position.

`
`Zemlock, FIG. 10.
`
`
`
`41. Zemlock states: “The first position, illustrated in FIGs. 5 and 6,
`
`enables rotation of end effector 160; the second position, illustrated in FIG. 7,
`
`enables articulation of end effector 160; and the third position, illustrated in FIGS.
`
`9-11 and 14, enables actuation of powered surgical instrument 100.” Zemlock,
`
`¶48. Zemlock also discloses that in place of a shift motor, a three-position
`
`solenoid can be used. Id., ¶47 (“It is envisioned that a three-position solenoid, for
`
`instance, can be used as an alternative to shift motor 220.”), FIGs. 4-7, 9-11 and
`
`14.

`
`Timm Application
`
`42. The Timm Application discloses a “surgical instrument that has an
`
`elongate channel assembly configured to operably support a staple cartridge
`
`therein.” Timm Application, Abstract. Notably, the Timm Application discloses
`
`an articulation joint 1512 that is nearly identical to the articulation joint disclosed
`
`in the ’431 Patent. Compare Timm Application, ¶182, FIG. 41 with ’431 Patent,
`
`FIG. 145.
`
`
`X. APPLICATION OF THE PRIOR ART TO THE ’431 PATENT
`
`
`
`A. Ground 1: Claims 1-6 and 10-13 would have been Obvious over
`Tierney in view of Whitman
`
`[1.1] A tool mounting device for coupling a surgical end effector configured to
`selectively perform at least two actions in response to control motions applied
`thereto to a tool drive assembly of a robotic system that is operatively coupled to
`a control unit of the robotic system, said tool mounting device comprising
`
`43.
`
`If this preamble is a limitation, then Tierney discloses it.

`
`drive assembly of a robotic system . . .”
`
`44. Tierney discloses a tool mounting device (the combination of rigid
`
`shaft 102 and proximal housing 108) for coupling a surgical end effector 112 to a
`
`tool drive assembly (the combination of tool holder 129, drive elements 119, and
`
`motors 70). Tierney, FIGs. 1-7L, 14A-C.

`
`
`
`As shown above in FIGs. 4 and 7F, rigid shaft 102 couples end effector 112 to
`
`proximal housing 108, and adapter 128 couples proximal housing 108 to the
`
`combination of tool holder 129, drive elements 119, and motor 70 of manipulator
`
`58. Id.
`
`45. The tool drive assembly is part of a “robotic surgical system 10[,
`
`which] generally includes master controller 150 and a robotic arm slave cart 50.”

`
`As noted above in Section IX.B, the Tierney surgical robot is incorporated by
`
`reference into the ’431 Patent, and the ’431 Patent figures are strikingly similar to
`
`
`
`Tierney’s figures.
`
`“Surgical end effector configured to selectively perform at least two actions
`
`in response to control motions applied thereto”
`
`46. Tierney’s end effector 112 is configured to selectively perform at least
`
`two actions (e.g., at least two of rotation, opening, closing, cutting, and
`
`articulating) in response to control motions provided by “drive system 116.”
`
`Tierney, 9:19-10:11, FIGs. 4A-5H. As explained in Tierney, “drive system 116

`
`mechanically couples first and second end effector elements 112a, 112b to driven
`
`elements 118 of interface 110 [of proximal housing 108]. . . . Stated simply, the
`
`drive system [116] translates mechanical inputs from driven elements 118 into
`
`articulation of the wrist about first and second axes A1, A2, as well as into
`
`actuation of the two element end effector by relative movement of the end effector
`
`elements about axis A2.” Id., 9:19-28. Accordingly, “articulation of the wrist”
`
`and “actuation of the two element end effector” comprise the recited “at least two
`
`actions” that the surgical end effector can perform.
`
`In FIG. 4B of Tierney, control connections are drawn schematically, illustrating
`
`
`
`27
`
`Action 1: articulation of end effector components about axis A1
`
`“End
`effector
`elements
`112a,
`112b”
`
`“Driven elements 118”
`
`Action 2:
`relative

`end effector
`elements
`about axis A2

`
`the control motions for articulation and opening and closing. In Tierney’s primary
`
`embodiments, control cables are used to make the control connections. The
`
`control cables are controlled independently and therefore allow various actions to
`
`be performed selectively. Articulation and opening of the jaws are two such
`
`actions.
`
`“[The tool drive assembly of a robotic system] is operatively coupled to a
`
`control unit of the robotic system”
`
`47. Tierney’s tool drive assembly (the combination of tool holder 129,
`
`drive elements 119, and motor 70 of manipulator 58) is operatively coupled to a
`
`control unit (master controller 150) of robotic surgical system 10. Tierney, 7:1-3,
`
`11:30-32, 12:45-58, FIGs. 1-2B, 8A-9. As shown below, drive elements 119 of
`
`tool holder 129 are part of manipulator 58, which is operatively coupled to
`
`processor 152 of master controller 150 by remote interface adapter (RIA) 56. Id.
`
`The surgeon would sit at the master controller and manipulate the user interface
`
`and such manipulation is translated into signals that control the motors in the tool
`
`drive assembly.

`
`[1.2] a tool mounting portion configured for operable attachment to the tool
`drive assembly of the robotic system
`
`48. Tierney discloses this limitation. As shown above in element [1.1],
`
`Tierney’s tool mounting device (the combination of rigid shaft 102 and proximal
`
`housing 108) includes a tool mounting portion (proximal housing 108) configured
`
`for releasable attachment to the tool drive assembly (the combination of tool holder
`
`129, drive elements 119, and motor 70) of robotic surgical system 10. Tierney,
`
`10:44-11:32, FIG. 7F. As explained in Tierney, “[a
