`
`II.
`
`INTRODUCTION
`
`Inter Partes Review of USPN 6,205,411
`
`The ’411 patent was filed on November 12, 1998. It has three independent
`
`claims and 14 dependent claims, all directed to methods and systems for planning
`
`and guiding implantation of an artificial component into a joint (hip, knee, hand
`
`and wrist, elbow, shoulder, or foot and ankle). The same systems and methods,
`
`however, were described in detail by several of the named inventors in articles
`
`published at least as early as 1996 and 1995, both well over a year before the ’411
`
`patent was filed. As a result, the’411 patent claims are unpatentable.
`
`The ’411 patent is a continuation-in-part of an application filed February 21,
`
`1997, which issued as U.S. Patent No. 5,880,976 (“the ’976 patent”). The
`
`independent claims of the ’411 patent, however, specifically recite implantation in
`
`“a hip joint, a knee joint, a hand and wrist joint, an elbow joint, a shoulder joint,
`
`[or] a foot and ankle joint.” Other than the hip joint, this is new matter with no
`
`support in the parent application, as the parent merely disclosed a “joint” and only
`
`specifically discussed a hip joint. This new matter is included in each claim that
`
`remains in the ’411 patent. All of the claims are therefore entitled only to their
`
`actual filing date of November 12, 1998.
`
`The Examiner’s views on priority are unclear from the prosecution history.
`
`In an April 5, 2000, office action, the Examiner stated that because the scope of the
`
`sf-3468564
`
`2
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`’976 patent was open-ended, it covered “joint” generally as recited in the ’976
`
`patent and also the specific joints recited in the ’411 patent claims. (Ex. 1002 at
`
`265.) On the next page of the same office action, the Examiner incorrectly and
`
`more broadly stated that the ’976 patent actually disclosed and claimed “[a]n
`
`apparatus for facilitating the implantation of an artificial component in one of a hip
`
`joint, a knee joint, a hand and wrist joint, an elbow joint, a shoulder joint, and a
`
`foot and ankle joint.” (Id. at 266.) In the September 21, 2000, Notice of
`
`Allowance, however, the Examiner pointed to the same specific language as the
`
`patentable improvement provided by the ’411 patent over the ’976 patent:
`
`The instant application is directed to a nonobvious
`
`improvement over the invention described in U.S. Patent
`
`No. 5,880,976 . . . . The improvement comprises an
`
`apparatus for facilitating the implantation of an artificial
`
`component in one of a hip joint, a knee joint, a hand and
`
`wrist joint, an elbow joint, a shoulder joint, and a foot
`
`and ankle joint. This patentable distinction is included in
`
`each of the independent claims 1, 10, and 29. (Id. at 287-
`
`88.)
`
`The Examiner’s September 21, 2000, view is partially correct: the specific
`
`list of joints is indeed a distinction between the ’411 patent and its parent. The
`
`distinction is not, however, patentable. The purported invention was thoroughly
`
`described years earlier, both in an article published at least as early as 1996, two
`
`sf-3468564
`
`3
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`years before the continuation-in-part filing date, which is the earliest priority date
`
`to which the ’411 patent is entitled; and in an article published at least as early as
`
`1995, which is 1-2 years before even the filing date of the ’976 parent application.
`
`This Petition for inter partes review shows how DiGioia (Ex. 1005), an
`
`article published at least as early as 1996, and DiGioia II (Ex. 1006), an article
`
`published at least as early as 1995, anticipate or render obvious each of the
`
`Challenged Claims of the ’411 patent. Indeed, these references disclose nearly all
`
`of the ’411 claimed methods and systems, with only a few minor differences that
`
`would have been obvious in view of other art. Part III of this Petition summarizes
`
`the ’411 patent, its prosecution history, and priority, and Part IV sets forth the
`
`detailed grounds for invalidity of the ’411 patent’s challenged independent and
`
`dependent claims in view of DiGioia, DiGioia II plus Chao, and other prior art.
`
`Petitioner has established a reasonable likelihood that it will prevail on at least one
`
`claim of the ’411 Patent, if not all of them. Accordingly, Petitioner respectfully
`
`requests a Decision to institute inter partes review.
`
`III. THE ’411 PATENT
`
`A.
`
`Background and Summary of Patent
`
`The ’411 patent is directed to systems and methods for facilitating
`
`implantation of an artificial component in a hip joint, knee joint, hand and wrist
`
`joint, elbow joint, shoulder joint, or foot and ankle joint. The apparatus and related
`
`sf-3468564
`
`4
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`method consist of essentially two pieces: a pre-operative geometric planner and a
`
`pre-operative kinematic biomechanical simulator that communicates with the
`
`geometric planner.
`
`The ’411 specification describes as background several challenges and
`
`concerns related to hip arthroplasty, which is a procedure to restore the function of
`
`a joint by resurfacing, remodeling, or complete replacement. Dislocation of the
`
`implanted component was known to be a major problem, but could be lessened
`
`with certain implantation angles. (Ex. 1001 at 1:37-55.) Variations in individual
`
`anatomies were also known to cause complications, as there is no single optimal
`
`component design and orientation. (Id. at 2:56-61.) According to the ’411
`
`specification, most prior operation planning methods for hip joint surgery used
`
`acetate templates and a single anterior-posterior x-ray, providing only a two-
`
`dimensional image of the pelvis. (Id. at 3:10-18.) The ’411 specification states
`
`that prior intra-operative positioning devices assumed that the pelvis and trunk
`
`were aligned in a known orientation and did not take into account individual
`
`anatomies. (Id. at 3:19-32.) Several other prior solutions assumed that a correct
`
`and precise implant position would be provided, and therefore did not solve the
`
`issue of determining or confirming a high-quality implant position. (Id. at 4:28-
`
`41.)
`
`sf-3468564
`
`5
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`The ’411 applicants proposed to address these problems by combining a pre-
`
`operative geometric planner and a kinematic biomechanical simulator. (Ex. 1001
`
`at 4:59-65.) The geometric planner creates geometric models of both the target
`
`joint and the artificial components to be implanted. (Id. at 5:63-67.) The simulator
`
`simulates movement of the joint to assist in determining implant positions,
`
`including angular orientation. (Id. at 6:1-5.) In some embodiments, the positions
`
`and geometric models are used with intra-operative navigational software to guide
`
`the surgeon. (Id. at 6:45-48.) In others, all three pieces—the planner, the
`
`simulator, and the navigational software—are implemented using a computer
`
`system with a display monitor. (Id. at 6:8-12.) The computer system could include
`
`a tracking device so relative locations of objects can be tracked and displayed
`
`during the operation. (Id. at 6:21-26.)
`
`The ’411 patent has three independent claims and 14 dependent claims.
`
`Independent claim 1 specifies the joints into which an artificial component will be
`
`implanted and claims a pre-operative geometric planner and a pre-operative
`
`kinematic biomechanical simulator in communication with the geometric planner.
`
`Independent claim 10 claims a computer system with the components set out in
`
`claim 1, and adds a tracking device in communication with the system.
`
`Independent claim 17 is directed to a method of facilitating implantation of an
`
`artificial component into one of the specified joints, comprising the steps of:
`
`sf-3468564
`
`6
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`creating a bone model; creating a component model; simulating movement of the
`
`joint with the implant; calculating a range of motion; determining an implant
`
`position based on a predetermined range of motion and the calculated range of
`
`motion; identifying the implant position in the bone model; aligning the bone
`
`model with the actual bone and placing the implant based on tracking data; and
`
`tracking the implant and bone to maintain alignment.
`
`B.
`
`Prosecution History and Priority
`
`The ’411 patent was filed on November 12, 1998. It is a continuation-in-
`
`part of application 08/803,993 (“the ’993 application”), which was filed on
`
`February 21, 1997, and issued as the ’976 patent. (Ex. 1003.) All three
`
`independent claims in the ’411 patent recite implantation in “a knee joint, a hand
`
`and wrist joint, an elbow joint, a shoulder joint, [or] a foot and ankle joint.”
`
`(Ex. 1001 at Abstract.) This specific list is in the preamble of each independent
`
`claim, and provides antecedent basis for “the joint” in the claim language of each.
`
`See Highmark, Inc. v. Allcare Health Mgmt. Sys., 687 F.3d 1300, 1311 (Fed. Cir.
`
`2012) (preamble limiting where “limitations in the body of the claim rely upon and
`
`derive antecedent basis from the preamble”) (quotations and citation omitted),
`
`rev’d on other grounds, 134 S. Ct. 1744 (2014).
`
`The specific joints set out in the preamble constitute subject matter not
`
`found in the ’993 application or ’976 patent, as that application and patent
`
`sf-3468564
`
`7
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`disclosed “joint” generally with “hip” as the only specific example. (See, e.g., Ex.
`
`1003 at 21, 1:17-33 (discussing hip replacement operations).) Adding specificity
`
`to narrow claims after an earlier, broader disclosure constitutes new matter, and the
`
`’411 patent claims are therefore not supported by the disclosure of the ’993
`
`application. MPEP § 2163.05 Part II (“The introduction of claim changes which
`
`involve narrowing the claims by introducing elements or limitations which are not
`
`supported by the as-filed disclosure” constitutes new matter.). As a result, the ’411
`
`patent is only entitled to its own filing date for all claims—not the filing date of the
`
`’993 application. See Cordance Corp. v. Amazon.com, Inc., 658 F.3d 1330, 1333-
`
`35 (Fed. Cir. 2011) (continuation-in-part claims not entitled to parent filing date
`
`where parent lacks written description support for CIP claims).
`
`The Examiner issued a single non-final rejection on April 5, 2000, on the
`
`grounds that 1) the claims were invalid due to non-statutory double patenting over
`
`claims of the ’976 patent; 2) the claims (particularly claims 1 and 10) were directed
`
`to non-statutory subject matter under 35 U.S.C. § 101, because they were “devoid
`
`of any limitation to a practical application” (Ex. 1002 at 269); and 3) the claims
`
`were invalid due to statutory double patenting over claims that were exact
`
`duplicates of claims of the ’976 patent.
`
`To resolve the double patenting rejections, Patent Owner canceled the claims
`
`that were exact duplicates of claims of the ’976 patent and submitted a terminal
`
`sf-3468564
`
`8
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`disclaimer for the remaining claims. To resolve the Section 101 rejection, Patent
`
`Owner amended claims 1 and 10 to claim that the “pre-operative geometric planner
`
`outputs at least one geometric model of the joint and the pre-operative kinematic
`
`biomechanical simulator outputs a position for implantation of the artificial
`
`component.” (Ex. 1002 at 282.) Notably, this language specifies “the joint” and
`
`thus relies on the new matter language in the preamble for antecedent basis.
`
`The Patent Office issued a notice of allowance on September 21, 2000, and
`
`the ’411 patent issued on March 20, 2001.
`
`IV. DETAILED EXPLANATION OF GROUNDS FOR INVALIDITY
`
`Pursuant to 37 C.F.R. §§ 42.22(a)(1) and 42.104(b), Petitioner respectfully
`
`requests the cancellation of claims 1-17 of the ’411 patent as they are unpatentable
`
`for the reasons set forth in this Petition. Specifically, Petitioner shows below that
`
`all of the claims of the ’411 patent are anticipated or rendered obvious by the ’411
`
`inventors’ own disclosures well over a year before the ’411 patent was filed. As
`
`demonstrated in Part IV.B, DiGioia is an article published at least as early as 1996
`
`that teaches nearly all of the elements of the claimed systems and methods, with
`
`only minor variations that would have been obvious to one of skill in the art.
`
`DiGioia II is an article published even earlier that teaches, in combination with
`
`another article by the same authors, the claimed systems and methods as well.
`
`sf-3468564
`
`9
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`In each of the following sections, Petitioner sets forth the specific art and
`
`statutory grounds on which the challenge is based in a table at the beginning of the
`
`section. 37 C.F.R. §§ 42.22(a)(2) and 42.104(b)(2). Petitioner then presents a
`
`discussion of how the claims are unpatentable under the statutory grounds raised.
`
`37 C.F.R. § 42.104(b)(4). Finally, Petitioner sets forth a claim chart that specifies
`
`where each element of each of the Challenged Claims is met by the prior art for
`
`ease of reference. Id. The showing in these sections establishes more than a
`
`reasonable likelihood of prevailing as to each ground of invalidity.
`
`The grounds for invalidity set forth below are supported by the declaration
`
`of Robert Howe, who provides testimony regarding the prior art and the
`
`understanding of one of ordinary skill in the art. Robert Howe’s declaration is
`
`attached as Exhibit 1004. Petitioner notes that during inter partes review a claim is
`
`given the “broadest reasonable construction in light of the specification.” See 37
`
`C.F.R. § 42.100(b). Petitioner submits, for the purposes of this inter partes review
`
`only, that claim terms are presumed to take on their broadest reasonable ordinary
`
`and customary meaning to a person of ordinary skill in the art in light of the
`
`specification of the ’411 patent. Petitioner reserves the right to advocate a different
`
`claim construction in district court or any other forum.
`
`A. DiGioia.
`
`Ground 1 is based on DiGioia (Ex. 1005) and is addressed below.

`(“DiGioia II”) (Ex. 1006) and
`knowledge of person of ordinary
`skill.
`
`
`
`DiGioia is an article published at least as early as 1996. (See Ex. 1002 at 96
`
`(Patent Owner admitting in IDS that DiGioia has a 1996 publication date).) As
`
`discussed above, the earliest priority date for claims 1-17 of the ’411 patent can be
`
`no earlier than November 12, 1998, two years later. Thus, DiGioia qualifies as
`
`prior art under § 102(b).
`
`DiGioia describes a system and methods to determine optimal implant
`
`placement during hip replacement surgery through the use of pre-operative
`
`planning, a range of motion simulator, and intra-operative navigational tracking
`
`and guidance. As it explains, a common problem causing complications after hip
`
`replacement surgery is poor positioning of the implant. The DiGioia system,
`
`sf-3468564
`
`11
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`called HipNav, allowed the surgeon to specify a component position, after which
`
`the range of motion simulator would estimate femoral range of motion based on
`
`parameters provided by the pre-operative planner. The feedback from the
`
`simulator allowed the surgeon to determine patient-specific optimal implant
`
`placement. The intra-operative tracking and guidance helped place the implant in
`
`that optimal position, regardless of the position of the patient on the operating
`
`table.
`
`DiGioia is clearly relevant to the patentability of the claims of the ’411
`
`patent, as it describes in detail the systems and methods claimed in the ’411 patent
`
`over a year before the ’411 patent was filed. Like the system disclosed in the
`
`’411’s independent system claims 1 and 10, DiGioia discloses:
`
`(1) a computer system for facilitating implantation of an artificial
`
`component in one of the specified joint types (Ex. 1005 at 1 (HipNav “allows a
`
`surgeon to determine optimal patient specific acetabular implant placement and
`
`accurately achieve the desired acetabular implant placement during surgery”)) with
`
`(2) a pre-operative geometric planner (id. at 2 (“[P]re-operative planner
`
`allows the surgeon to manually specify the position of the acetabular component
`
`within the pelvis based upon pre-operative CT images,” and is therefore
`
`geometric)) and
`
`sf-3468564
`
`12
`
`
`
`
`
`(3) a pre-operative kinematic biomechanical simulator in
`
`Inter Partes Review of USPN 6,205,411
`
`communication with the geometric planner (id. at Fig. 3 (depicting range of
`
`motion simulator with arrows illustrating communication between simulator and
`
`planner)), where
`
`(4) the geometric planner outputs a geometric model of the joint (id. at 2
`
`(simulator receives from pre-operative planner implant placement parameters,
`
`which are necessarily based upon and described relative to geometric model of
`
`joint)), and
`
`(5) a tracking device communicating with the computer system (id. at 4
`
`(intra-operative system includes Optotrak optical tracking camera capable of
`
`tracking special LEDs)).
`
`Similarly, like the method disclosed in the ’411’s independent method claim
`
`17, DiGioia discloses a computerized method:
`
`(1) for facilitating implantation of an artificial implant in one of the
`
`specified joint types (Ex. 1005 at 1), comprising
`
`(2) creating a three-dimensional bone model (id. at 5-6, Fig. 8 (system
`
`uses pelvic surface model constructed from CT data using techniques discussed in
`
`three-dimensional modeling article)),
`

`
`(3) creating a three-dimensional component model (id. at Fig. 4
`
`(depicting positioning of implant component across three orthogonal views of
`
`pelvis)),
`
`(4) simulating movement of the joint with the artificial implant in a test
`
`position (id. at 2 (discussing range of motion simulator)),
`
`(5) calculating a range of motion (id. at 3-4 (simulator performs kinematic
`
`analysis to determine envelope of safe range of motion)),
`
`(6) identifying the implant position in the bone model (id. at 3 (surgeon
`
`can position cross sections of implant upon orthogonal view of pelvis)),
`
`(7) aligning the bone model with the bone based on tracking data (id. at
`
`5 (disclosing registration process to align position of patient to pre-operative
`
`plan)), and
`
`(8) tracking the implant and bone to maintain alignment and determine
`
`the position of the implant relative to the bone (id. at 5-7 (discussing tracking of
`
`implant and bone and use of navigational feedback)).
`
`The few claim elements that are not explicitly disclosed by DiGioia are
`
`minor, obvious variations. For example, claim 1 requires the pre-operative
`
`kinematic biomechanical simulator to output a position for implantation of the
`
`artificial component. The DiGioia system discloses that feedback from the
`
`simulator can aid the surgeon in determining optimal implant placement.

`
`(Ex. 1005 at 2.) It would have been obvious to utilize the feedback to modify the
`
`position of an implant, re-run the simulation to determine optimal position, and
`
`output that position to the pre-operative planner. (Ex. 1004 ¶ 38.) This is also
`
`suggested by DiGioia Figure 3, which depicts bi-directional communication
`
`between the pre-operative planner and the range of motion simulator. (Id.)
`
`Similarly, claim 17 requires the system to determine an implant position based on a
`
`predetermined range of motion and the calculated range of motion. DiGioia
`
`discloses calculation of a range of motion and states the surgeon may choose to
`
`modify a selected position to achieve optimal implant positioning. (Ex. 1005 at 3.)
`
`It would have been obvious to consider the specific patient’s functional needs and
`
`the range of motion needed to perform those functional needs, which could be
`
`predetermined, to help in determining optimal implant positioning. (Ex. 1004
`
`¶ 41.)
`
`DiGioia also matches the ’411 patent’s dependent claims:
`
`• Claims 2 and 15 add an intra-operative navigational module in
`
`communication with the pre-operative kinematic biomechanical
`
`simulator. DiGioia illustrates that the system also includes an “Intra-
`
`operative Tracking & Guidance” component. DiGioia indicates that
`
`this component includes an “intra-operative guidance system” which
`
`includes “registration of pre-operative information . . . to the position
`
`sf-3468564
`
`15
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`of the patient. (Ex. 1005 at 5.) Once anatomical location is
`
`determined “via registration, navigational feedback can be provided to
`
`the surgeon on a television monitor, as seen in Figure 9.” (Id. at 6.)
`
`• Claim 3 requires a tracking device in communication with said intra-
`
`operative navigational module. DiGioia discloses that the intra-
`
`operative system includes “an ‘Optotrak’ optical tracking camera . . .
`
`which is capable of tracking the position of special light emitting
`
`diodes . . . to allow highly reliably tracking.” (Ex. 1005 at 4.) “In
`
`order to determine the location of the pelvis and the acetabular
`
`implant during surgery, Optotrak targets are attached to several
`
`conventional surgical tools, as seen in Figure 7.” (Id.) DiGioia
`
`indicates that “[o]nce the location of the pelvis is determined . . .
`
`navigational feedback can be provided to the surgeon.” (Id. at 6.)
`
`Thus, because the navigation module relies upon the tracking device,
`
`the navigation module is in communication with the tracking device.
`
`• Claim 4 requires the pre-operative geometric planner to be responsive
`
`to a skeletal data source. DiGioia states that the “first step in using
`
`the HipNav system is the pre-operative CT scan which is used to
`
`determine the patient’s specific bony geometry. The CT images are
`
`used in the pre-operative planner which allows the surgeon to
`
`sf-3468564
`
`16
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`determine appropriate implant size and placement.” (Ex. 1005 at 3.)
`
`Therefore, the data source inherently is a skeletal data source.
`
`• Claim 5 adds that the skeletal data source includes geometric data.
`
`DiGioia states that “the pre-operative CT scan . . . is used to determine
`
`the patient’s specific bony geometry” (Ex. 1005 at 3) and therefore the
`
`skeletal data source inherently includes geometric data.
`
`• Claim 6 requires the geometric planner to output at least one
`
`geometric model of the component. DiGioia states that the “pre-
`
`operative planner allows the surgeon to manually specify the position
`
`of the acetabular component within the pelvis . . . [and then] [t]he
`
`range of motion simulator estimates femoral range of motion based
`
`upon the implant placement parameters provided by the pre-operative
`
`planner.” (Ex. 1005 at 2.) Thus, the pre-operative planner outputs a
`
`geometric model of the component to the range-of-motion simulator.
`
`• Claim 7 requires the pre-operative kinematic biomechanical simulator
`
`to be responsive to the geometric model and output an implant
`
`position. As noted under claim 6, “[t]he range of motion simulator
`
`estimates femoral range of motion based upon the implant placement
`
`parameters provided by the pre-operative planner” (Ex. 1005 at 2) and
`
`therefore is responsive to said geometric model. As discussed under
`
`sf-3468564
`
`17
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`claim 1, it would have been obvious to a person of skill in the art to
`
`utilize the simulator feedback to modify the position of an implant, re-
`
`run the simulation to determine optimal position, and output that
`
`position to the pre-operative planner. (Ex. 1004 ¶ 38.)
`
`• Claim 8 requires the implant position to include an angular orientation
`
`of the component. DiGioia notes that using navigational feedback
`
`provided to the surgeon, “[o]nce aligned, the implant is in the pre-
`
`operatively planned position and orientation.” (Ex. 1005 at 6.) Thus,
`
`pre-operative planning involves determining both the position and
`
`orientation of the implant location.
`
`• Claim 9 adds that the tracking device must be selected from the group
`
`consisting of an acoustic tracking system, shape based recognition
`
`tracking system, video-based tracking system, mechanical tracking
`
`system, electromagnetic tracking system and radio frequency tracking
`
`system, and claim 13 requires that the tracking device include at least
`
`one camera. DiGioia discloses an Optotrak camera-based tracking
`
`system. (Ex. 1005 at 4.) Even if this was not considered a video-
`
`based tracking system, video-based tracking systems were widely
`
`used and known to those of skill in the art in the mid-1990s, and it
`
`would have been obvious to combine video-based capability with the
`
`sf-3468564
`
`18
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`DiGioia system or substitute a video-based tracking system for the
`
`Optotrak camera system. (See Ex. 1004 ¶ 39.)
`
`• Claim 11 adds a display monitor in communication with the computer
`
`system of claim 10. DiGioia states that using “the planner, the
`
`surgeon can position cross sections of the acetabular implant upon
`
`orthogonal views of the pelvis, as seen in Figure 4.” (Ex. 1005 at 3.)
`
`This user interface of the pre-operative planner is a display monitor in
`
`communication with the computer of the pre-operative planner.
`
`• Claim 12 adds a controller in communication with the computer
`
`system. DiGioia states that the “pre-operative planner allows the
`
`surgeon to manually specify the position of the acetabular component
`
`within the pelvis.” (Ex. 1005 at 2.) A controller, such as a mouse,
`
`joystick or keyboard, or voice-activated control, would necessarily
`
`have been provided to allow the surgeon to manually specify the
`
`implant position.
`
`• Claim 14 adds that the tracking device includes at least one target.
`
`DiGioia states that “[i]n order to determine the location of the pelvis
`
`and the acetabular implant during surgery, Optotrak targets are
`
`attached to several conventional surgical tools, as seen in Figure 7.
`
`The pelvis is tracked by attaching a target to the pelvic portion of a
`
`sf-3468564
`
`19
`
`
`
`
`
`Inter Partes Review of USPN 6,205,411
`
`Harris leg length caliper . . . . The acetabular implant is tracked by
`
`attaching a second target to the handle of an HGP II acetabular cup
`
`holder and positioner . . . . A third Optotrak target is required by the
`
`HipNav system to determine operating room coordinates . . . .” (Ex.
`
`1005 at 4-5.)
`
`• Claim 16 adds the requirement of a robotic device and surgical tool.

`Computer Assisted Surgery in Orthopaedics,” Proc. 1st Int’l
`
`Symposium on Medical Robotics and Computer Assisted Surgery, pp.
`
`106-111, 1995 (“DiGioia II”) (Ex. 1006). DiGioia II discloses an
`
`approach to improved surgical techniques incorporating pre-operative
`
`planning with biomechanical analysis and computer or robot-assisted
`
`surgery. (Ex. 1006 at 3.) It depicts a c
