`
`
`
`I, Dr. Robert E. Jacobson, MD, of Miami, Florida, declare that:
`
`l. Qualifications
`
`1.
`I am a neurosurgeon with a specialty in spine surgery including spinal
`discectomy and fusion procedures.
`I graduated from medical school in 1969, and
`
`performed general neurosurgery residencies with a research concentration on spine from
`
`1970 through 1975.
`
`I also performed a clinical fellowship in cervical and lumbar spine
`
`surgery under Professor Henk Verbiest from July 1975 to March 1976 in Utrecht,
`
`Netherlands.
`
`I am the inventor of the spinal surgery methods and equipment described,
`
`among other places, in US. Patent No. 4,545,374 (“’374 patent”) (Exhibit 1004), entitled
`
`“Method and instruments for performing a percutaneous lumbar diskectomy,” which is a
`
`patent I had filed on September 3, 1982, and which issued on October 8, 1985.
`
`2.
`
`l have been asked to provide rebuttal testimony to the declaration testimony
`
`of Dr. Barton Sachs regarding what is disclosed in my ‘374 patent.
`
`In this regard, I have
`
`reviewed W 75-93 of Dr. Sachs’ declaration (Exhibit 2038, hereafter “Dr. Sachs Decl.”),
`
`where he provides his opinions regarding my ‘374 patent.
`
`I am very familiar with my own
`
`‘374 patent, although I reviewed my ‘374 patent again as part of my study in providing this
`
`declaration.
`
`I also reviewed other documents referenced in my testimony set forth below.
`
`3.
`
`Dr. Sachs, in his declaration, states that “[t]hough Jacobson uses the word
`
`‘lateral,’ the term does not mean direct lateral.” Dr. Sachs Decl., 1T 75. Dr. Sachs also
`
`states that “Jacobson does not teach a direct lateral approach to the spine,” and further
`
`1
`
`2
`
`
`
`states that he “believe[s] he [Dr. Jacobson] is teaching a similar approach that is
`
`posterolateral.” Dr. Sachs Decl.,1) 76. Copied below is the figure from Dr. Sachs
`
`declaration where he illustrates a “posterolateral approach,” and also illustrates a “direct
`
`lateral approach.”

`

`
`4.
`
`i agree with Dr. Sachs that a posterolateral approach (as labeled in the figure
`
`copied above from his declaration) is different from a direct lateral approach (as also labeled
`
`in the figure copied above).
`
`(I note, however, that approaches referred to as “posterolateral”
`
`may be, and in fact are typically, more posterior than the posteriolateral approach shown in
`
`the figure above.)
`
`I disagree, however, with Dr. Sachs’ opinion that my ‘374 patent teaches
`
`a posterolateral approach and not a direct lateral approach. My ‘374 patent clearly teaches
`
`a direct lateral approach, not a posterolateral approach.
`
`indeed, the approach that I had
`
`developed and used at the time was a direct lateral approach, not a posterolateral
`
`approach.
`
`I believe it is clear — from the figures and the text of my ‘374 patent, especially in
`
`2
`
`3
`
`
`
`view of the timeframe of the early 19805 during which I developed and had a patent filed on
`
`my lateral procedure — that my ‘374 patent discloses a direct lateral approach. For
`
`example, the patient in my method of the ‘374 patent is always placed in a lateral decubitus
`
`(side) position, and the three access instruments including the final access cannula are
`
`passed to the spine using a direct lateral approach. See, e.g., my ‘374 patent, Exhibit 1004,
`
`column 5, lines 5-6 (“To begin the procedure, the patient 6 is placed in the lateral decubitus
`
`position ....”,) column 5, lines 27-28 (“As shown in FIG. 3, the needle is inserted laterally
`
`through the patient’s side above the pelvic crest ....”,) column 5, lines 49-50 (“The speculum
`
`10 is laterally inserted through body tissue ....), column 5, lines 60-62 (“Once the speculum
`
`is properly positioned, the surgeon spreads its jaw blades thereby creating a channel for
`
`cannula insertion”), Figures 3-6.
`
`In this regard, Figure 5 is particularly clear in illustrating
`
`the direct lateral nature of the approach, given that the distal end of the cannula 11 is
`
`depicted in the figure with a straight horizontal line (i.e., not in perspective), thereby
`
`indicating the view of the cannula 11 is a side view or in other words the cannula 11 lies in a
`
`plane that is parallel with the page. Also in Figure 5, the transverse processes that extend
`
`from the two vertebral bodies are sized to be about the same size, thus indicating the view
`
`in Figure 5 of the spine is directly from the front of the spine.
`
`In addition, my ‘374 patent
`
`describes that the entry to the disc space is from the side opposite the disc bulge, such that
`
`the instruments pass all the way across the disc in order to get to the bulge. See, e. 9., my
`
`‘374 patent, Exhibit 1004, column 7, line 67 to column 8, line 5. Extending instruments
`
`3
`
`4
`
`
`
`across the disc to a bulge on the other side of the disc would not be possible with a
`
`posterolateral approach and the instruments I describe in my ‘374 patent.
`
`5.
`
`When I was in the process of developing the method shown in my ‘374 patent
`
`during the early 19803 and working with attorneys from the law firm of Pennie & Edmonds
`
`on the patent application that became my ‘374 patent, the phrase “direct lateral” was not a
`
`phrase that I used in the technical parlance of my profession, and in fact, at that time i had
`
`never heard the phrase “direct lateral” to describe a 90 degree lateral approach to the spine.
`
`Instead, in the early 19803, I (and others) simply used the term “lateral” when referring to a
`
`90 degree lateral approach to the spine. When we wanted to refer to a posterolateral
`
`approach to the spine (which was also known at the time), we called that approach a
`
`posterolateral approach.
`
`It is only recently in the last few years that | first heard the phrase
`
`“direct lateral” in referring to a 90 degree lateral approach.
`
`6.
`
`The posterolateral approach to the spine was well known when l was doing
`
`my work developing my lateral method in the early 19803. The posterolateral approach
`
`dates back to the 19403 with procedures that made injections into the spinal disc. For
`
`example, a posterolateral approach to the spine was used in the procedure discussed in the
`
`background section of my ‘374 patent to inject a chymopapain enzyme into the disc with a
`
`spinal needle. See my ‘374 patent, column 1, line 65 through column 2, line 5.
`
`In the
`
`19803, around the same time l was developing my lateral approach procedure, Dr. Parviz
`
`Kambin was developing his posterolateral procedure that involves providing an access
`
`4
`
`5
`
`
`
`cannula for access to the disc space of the spine along a posterolateral approach, and that
`
`is described in his patents. See, e.g., Exhibit 1013, U.S. Patent No. 4,573,448 to Kambin,
`
`Figure 10 and column 5, lines 5-6; Exhibit 1048, U.S. Patent No. 5,395,317 to Kambin,
`
`Figures 10-12, column 2, lines 45-46 and column 3, lines 64-66. Dr. Kambin’s
`
`posterolateral approach procedure was different from my direct lateral procedure. For
`
`example, my lateral procedure and Dr. Kambin’s posterolateral procedure differed from one
`
`another in that they involved different anatomical considerations in accessing the spine, and
`
`Dr. Kambin’s approach had certain advantages and disadvantages as compared to my
`
`direct lateral method described in my ‘374 patent. One of the advantages of my direct
`
`lateral approach, as compared to posterolateral approaches, is that my direct lateral
`
`approach provided for a larger access cannula to the spine that is anatomically impossible
`
`to place in a posterolateral position because the different anatomic structures composing
`
`“Kambin’s triangle,” the nerve root, the facet joint, and the annulus limit the size of the
`
`space. All posterolateral approaches ever used — from discograms, chymopapain, and
`
`percutaneous discectomy — go behind the exiting nerve root. My lateral approach goes
`
`anterior or ventral of the nerve root. This allows a larger access port or cannula and a true
`
`90 degree lateral approach to the disc space providing the ability to manipulate the
`
`instruments completely across the disc space side to side (right to left or left to right) in the
`
`coronal plane as well as front to back (posterior to anterior or vice-versa) in the saggital
`
`6
`
`
`
`plane. For these reasons, my lateral approach was quite different from the posterolateral
`
`approaches then known.
`
`7.
`
`Indeed, during the 1980s, there were often debates at conferences regarding
`
`the relative merits of my direct 90 degree lateral approach versus Dr. Kambin’s
`
`posterolateral approach.
`
`In view of that background, I believe that it would have been well
`
`known among spine surgeons and others in the spinal medical community in the 19805 that
`
`posterolateral methods such as Dr. Kambin’s approached the spine from a different angle
`
`as compared to my direct lateral procedure described in my ‘374 patent.
`
`8.
`
`In addition, shortly after I had developed my direct lateral procedure set forth
`
`in my ‘374 patent, l began teaching that procedure to other orthopedic and neurologic
`
`surgeons.
`
`In the 19803, approximately 50 spine surgeons observed me perform the
`
`procedure described in my ‘374 patent, and many of them began doing the procedure
`
`themselves after the procedure. One of the first spine surgeons who observed me perform
`
`my direct lateral procedure was Dr. William A. Friedman, of the University of Florida, who is
`
`now Chairman of the Department of Neurosurgery at the University of Florida. He had
`
`heard me speak about my lateral method at a Florida Neurological Society meeting, and
`
`then invited me to the University of Florida to speak and perform the surgery on a patient
`
`with him using the same instruments and approach method set forth in my ‘374 patent.
`
`Following this visit and procedure, Dr. Friedman started performing the lateral surgeries as I
`
`had taught them to him, and he remained in contact with me while he was doing those
`
`6
`
`7
`
`
`
`procedures.
`
`In addition, and with my permission, Dr. Friedman authored one paper and co-
`
`authored another describing my direct lateral procedure that is also described in my ‘374
`
`patent. See Exhibit 1036, Friedman, Percutaneous Discectomy: An Alternative to
`
`Chemonuc/eo/ysis?, NEUROSURGERY, Vol. 13, No. 5, pp. 542-47 (1983) (stating at page 547
`
`that “[t]he author thanks Dr. Robert Jacobson for teaching him the percutaneous discectomy
`
`technique. Dr. Jacobson developed this methodology”) (hereafter “Friedman 1983 Paper”);
`
`see also Exhibit 1037, Kanter and Friedman, Percutaneous Discectomy: An Anatomical
`
`Study, NEUROSURGERY, Vol. 16, No. 2, pp. 141-147 (1985) (stating at page 146 that “[t]he
`
`authors recognize Dr. Robert Jacobson, who developed this methodology”) (hereafter
`
`“Kanter & Friedman 1985 Paper”).
`
`I believe it is clear from the figures and textual
`
`description in both of Dr. Friedman’s papers from 1983 and 1985, respectively, that the
`
`direct lateral procedure shown in Dr. Friedman’s papers is my direct lateral procedure as
`
`described in my ‘374 patent. See, e.g., Exhibit 1036, Friedman 1983 Paper, FIGS. 3-6, and
`
`p. 542, col. 2, line 4 through p. 544, col. 1, line 6; Exhibit 1037, Kanter & Friedman 1985
`
`Paper, FIGS. 1, 5 and 9-10, Table 1, and p. 141, col. 1, line 1 through p. 142, col. 1, line 11;
`
`Exhibit 1004, my ‘374 patent, throughout.
`
`I also believe it is clear that these papers
`
`(Exhibits 1036 and 1037) corroborate that my approach was a 90 degree lateral approach to
`
`the spine, as is shown for example in Figure 3 from Exhibit 1036 copied below:
`
`8

`inc lateral aspcci of thc narhologrml micrspam ch ULLI mu Md: of

`is. «mental.
`
`Accordingly, Dr. Friedman’s papers corroborate that my direct lateral approach to the spine
`
`was a 90 degree direct lateral approach, not a posterolateral approach.
`
`9.
`
`In 11 88 of his declaration, Dr. Sachs makes reference to the discussion in my
`
`‘374 patent where I state that my lateral access system may be used to perform other spinal
`
`procedures, including spinal fusion. See my ‘374 patent, column 6:9-13. Dr. Sachs states
`8
`
`9
`
`
`
`that my ‘374 patent does not “ever expressly reference an implant for performing a fusion.”
`
`Dr. Sachs declaration, 1f 88. Dr. Sachs then discusses a variety of things that may be
`
`implanted into a patient’s intradiscal space in order to accomplish fusion, and appears to
`
`use the term “implant” in a narrow sense to conclude that my ‘374 patents reference to
`
`fusion would not necessarily involve introduction of an implant into the patient. See Dr.
`
`Sachs declaration, W 88—89.
`
`10.
`
`Responding directly to Dr. Sachs’ testimony in 1111 88—89 of his declaration:
`
`First, the method disclosed in my ‘374 patent teaches a surgical procedure in which an
`
`access cannula is provided to a spinal disc space. Spinal disc spaces, of course, are
`
`located in the anterior column of the spine. The purpose of my method in providing such an
`
`access corridor to the disc space in the anterior column of the spine is to perform a spinal
`
`surgical procedure there. As such, the reference in my ‘374 patent to performing a fusion
`
`procedure through my disclosed direct lateral access cannula would necessarily involve
`
`implanting something into the disc space that would be intended to remain in the disc space
`
`after surgery to facilitate inter-body fusion. Beginning in the early 1980’s when I used my
`
`lateral access system disclosed in my ‘374 patent to perform a direct lateral fusion
`
`procedure on patients, I used allograft bone dowels readily available to me (which I
`
`customized/trimmed) as the implant I inserted laterally into the disc space to promote fusion
`
`between at least two adjacent vertebral bodies. Allograft bone dowels are implant
`
`structures that are made from bone obtained from cadaveric donors.
`
`In other words,
`
`9
`
`10
`
`10
`
`
`
`allograft bone dowels are not obtained from the patient who was undergoing the fusion
`
`procedure and ultimately received the bone dowel implant.
`
`(if it comes from the patient,
`
`such bone dowels were and are referred to as autograft implants). Allograft bone dowels
`
`were readily available to me for use as implants in fusion procedures as early as 1972
`
`through the University of Miami Tissue Bank where I trained and did research with Dr.
`
`Theodore Malinin.
`
`I worked with allograft bone grafts from 1972 both in the research lab
`
`and clinically. At that time, because of the close association and proximity of the University
`
`of Miami Tissue Bank, we routinely used allograft bone dowels for Cloward cervical inter-
`
`body fusion procedures, and so the concept of an intra—spinal allograft bone dowel was a
`
`concept with which I was quite familiar by the time I was developing my lateral fusion
`
`method in the early 1980’s. Additionally, the hospital where I developed my percutaneous
`
`discectomy technique was directly across the street from the Tissue Bank and | maintained
`
`my contact with them. We kept sterile bottled supplies of various size bone allograft in the
`
`operating room so it was straight-fonNard to decide to place an allograft through the
`
`percutaneous access cannula into the disc space.
`
`in a fusion procedure using my ‘374
`
`patented method, i would place one or more customized/trimmed allograft bone dowels
`
`across the disc space from side to side.
