No. 17 C 7216
Judge Sara L. Ellis

OPINION AND ORDER
In this patent infringement lawsuit, Plaintiff Medline Industries, Inc. (“Medline”) alleges
that Defendant C.R. Bard, Inc. (“Bard”) infringes claims of U.S. Patent Nos. 9,745,088 (“the
‘088 patent”), 9,795,761 (“the ‘761 patent”), and 9,808,596 (“the ‘596 patent”) (collectively,
“the patents-in-suit”) 1 that generally relate to the configuration of trays and kits used for
catheterization. After Bard served an expert report opining on the invalidity of the asserted
patent claims, Medline moved to strike certain portions of the expert report as violating this
District’s Local Patent Rules. Two days later, Bard responded in kind, moving to strike certain
portions of Medline’s expert report on infringement as violating the Local Patent Rules. Both
motions are now fully briefed. 2 Because Medline has shown that Bard failed to previously
disclose most, but not all, of the invalidity arguments contained in the challenged portions of
Bard’s expert report on invalidity, the Court grants in part and denies in part Medline’s motion to
strike [226]. And because Bard has shown that Medline failed to previously disclose the

1

Medline previously asserted another patent, U.S. Patent No. 9,808,400 (“the ‘400 patent”), but the ‘400
patent is no longer in dispute.

2

In connection with its opposition to Bard’s motion to strike, Medline filed an unopposed motion to seal
certain exhibits. The Court grants that motion [232].

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 2 of 30 PageID #:10094

infringement arguments contained in the challenged portions of Medline’s expert report on
infringement, the Court grants Bard’s motion to strike [228].
BACKGROUND
For more than a decade, this District has had Local Patent Rules. See Judge Matthew F.
Kennelly & Edward D. Manzo, Northern District of Illinois Adopts Local Patent Rules, 9 J.
Marshall Rev. Intell. Prop. L. 202, 202 (Winter 2010) (Local Patent Rules first took effect on
October 1, 2009). “These Local Patent Rules provide a standard structure for patent cases” and
“anticipate and address many of the procedural issues that commonly arise in patent cases.”
N.D. Ill. LPR preamble. Among other things, the Local Patent Rules require each party, “[a]fter
a reasonable period for fact discovery, . . . [to] provide a final statement of its contentions”
regarding infringement and invalidity, which the “party may thereafter amend only ‘upon a
showing of good cause and absence of unfair prejudice, made in timely fashion following
discovery of the basis for the amendment.’” Id. (quoting N.D. Ill. LPR 3.4); see N.D. Ill. LPR
3.1, 3.2.
In July 2018, the parties served their Final Infringement and Invalidity Contentions
pursuant to Local Patent Rule 3.1. A few months later, this District amended that rule. See N.D.
Ill. General Order 18-0022 (Oct. 26, 2018). The amendment requires the patentee to limit the
number of patent claims it asserts in its Final Infringement Contentions and the accused patent
infringer to limit the number of invalidity grounds it asserts in its Final Invalidity Contentions.
Id.; Medline Indus., Inc. v. C.R. Bard, Inc. (“Medline I”), No. 14 C 3618, Doc. 480 at 2 (N.D. Ill.
Jan. 8, 2020). 3 In February 2019, on motion from the parties, the Court ordered Medline to
narrow its asserted patent claims, as required by amended Local Patent Rule 3.1(a), by February

Another district court judge oversees the litigation between Medline and Bard in Case No. 14 C 3618.

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 3 of 30 PageID #:10095

22, 2019, and Bard to narrow its prior art and invalidity grounds, as required by amended Local
Patent Rule 3.1(b), by April 8, 2019.
Fact discovery closed on May 31, 2019. The Court then stayed the litigation from
September 2019 through July 2020 while the Patent Trial and Appeal Board conducted inter
partes reviews (“IPRs”) on all the asserted claims in the patents-in-suit. The claims in the
patents-in-suit survived the IPRs, and the Court thereafter set a schedule for expert discovery.
Per this schedule, the parties were to exchange opening expert reports by October 12, 2020 and
rebuttal reports by November 23, 2020, with expert discovery closing on February 15, 2021.
Medline served an opening expert report from Dr. John Abraham, who opined that Bard’s
SureStep “Bag” and “Meter” single-layer Foley catheter trays or kits infringe the asserted patent
claims. Bard served an opening expert report from Karl Leinsing, who opined that two primary
references—U.S. Patent No. 4,160,505 (“Rauschenberger”) and Bard’s Bardex® I.C. Catheter
Package Assemblies (“Bardex”)—combined with other references render the asserted claims
obvious. After each party identified issues with the other party’s expert report, the parties met
and conferred but were unsuccessful, leading to the current motions.
LEGAL STANDARD
“The Court has broad discretion to manage discovery matters and enforce the Local
Patent Rules.” Oil-Dri Corp. of Am. v. Nestle Purina PetCare Co. (“Oil-Dri II”), No. 15 C 1067,
2018 WL 3130943, at *4 (N.D. Ill. June 26, 2018). Because this District’s Local Patent Rules
are “unique to patent cases” and “are likely to directly affect the substantive patent law theories
that may be presented at trial, being designed specifically to require parties to crystallize their
theories of the case early in the litigation so as to prevent the shifting sands approach to claim
construction,” Federal Circuit law governs the Court’s interpretation of these rules. O2 Micro

meant to prevent a shifting sands approach to claim construction by forcing the parties to
crystallize their theories of the case early in litigation” (citation omitted) (internal quotation

The Local Patent Rules “do not specify the actions that the [Court] may or must take if
there is non-compliance with the requirements for disclosure of contentions.” O2 Micro, 467
F.3d at 1363. “However, the rules are essentially a series of case management orders,” and
under Rule 16(f), the Court “may impose any ‘just’ sanction for the failure to obey a scheduling
order,” such as “prohibiting the disobedient party from supporting or opposing designated claims
or defenses” or “from introducing designated matters in evidence,” as set forth in Rule
37(b)(2)(A)(ii). Id. (citations omitted); Fed. R. Civ. P. 16(f)(1)(C) (authorizing “any just orders,

“[T]he sanction selected must be one that a reasonable jurist, apprised of all the
circumstances, would have chosen as proportionate to the infraction.” Oil-Dri I, 2018 WL

material beyond the scope of the accused infringer’s Final Invalidity Contentions); Pactiv Corp.

24, 2013) (striking portions of an expert’s infringement reports that analyzed products the
patentee did not identify as being infringed in its infringement contentions). Unlike Rule
37(c)(1), which does not allow the exclusion of evidence as a sanction for a harmless failure to
disclose or supplement information under Rule 26(a) or (e), Rules 16(f)(1)(C) and
37(b)(2)(A)(ii) do not prohibit the exclusion of evidence even where the violation at issue does
not cause prejudice. Compare Fed. R. Civ. P. 16(f)(1)(C) and Fed. R. Civ. P. 37(b)(2)(A)(ii),
with Fed. R. Civ. P. 37(c)(1); see also Mortg. Grader, Inc. v. First Choice Loan Servs. Inc., 811
F.3d 1314, 1323 (Fed. Cir. 2016) (a district court does not “abuse its discretion by failing to
consider prejudice when it applied a rule that does not require consideration of prejudice”).
ANALYSIS
The Court begins with some initial observations that inform its analysis. Medline’s
expert had six weeks to draft and serve a report in response to Bard’s opening expert report on
invalidity; similarly, Bard’s expert had six weeks to draft and serve a report in response to
Medline’s opening expert report on infringement. To the extent either opening expert report
disclosed a particular infringement or invalidity theory for the first time, the Court questions
whether the parties’ experts could have used this time to adequately respond to the new theory in
their rebuttal expert reports, thereby dispelling any prejudice that may have accompanied the
new disclosure. Indeed, Bard contends that Dr. Abraham (Medline’s expert) could have “easily
respond[ed]” to the disclosures challenged by Medline in his rebuttal expert report, Doc. 234 at

5

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 6 of 30 PageID #:10098

15, 18–19, 4 although the Court notes Bard’s failure to explain why its own expert, Mr. Leinsing,
could not have likewise “easily respond[ed]” to the disclosures with which Bard takes issue.
Nonetheless, both Medline and Bard decided to channel their energy into seeking the
Court’s intervention and precluding the other party’s expert from presenting the purportedly
offending evidence. The rebuttal expert report deadline has now passed, and although each party
may still depose the other party’s expert, this does not allow the deposing party to present
affirmative evidence rebutting that expert’s theories—this would require giving each party the
opportunity to submit a supplemental rebuttal expert report before the close of expert discovery.
At this stage of the litigation and in these circumstances, the Court declines to do so, and it
concludes that the proper remedy for the disclosure of a previously undisclosed theory or
argument in either party’s expert report is preclusion. This is especially appropriate here because
the rules requiring a party to lay all its infringement or invalidity cards on the table in its Final
Contentions (absent a court order based on a showing of good cause and absence of unfair
prejudice) have governed patent litigation in this District for several years. See Kennelly &
Manzo, supra, at 216; N.D. Ill. General Order 13-0004, at LPR 3.1, 3.2, and 3.4 (Feb. 25, 2013).
The Court expects patent litigants to comply with these longstanding rules and disclose any
infringement and invalidity theories their experts may rely upon before proceeding to expert
discovery. See Avnet, 2016 WL 3365430, at *5 (“One of the purposes of final invalidity
contentions is to give notice to plaintiffs of the defendant’s contentions, and the bases for them,
prior to expert discovery.”); see also Hinterberger v. City of Indianapolis, 966 F.3d 523, 528 (7th
Cir. 2020) (noting, in the context of a district court’s non-patent local rules, that “district courts
may require strict compliance” with these rules). With these observations in mind, the Court
now proceeds to address each party’s motion to strike.

I.

Medline’s Motion to Strike
Medline moves to strike two aspects of Mr. Leinsing’s opening expert report. First, it

moves to prelude his reliance upon U.S. Patent No. 3,329,261 (“Serany”). Second, it moves to
strike his opinion that two combinations of references including U.S. Patent No. 5,931,303
(“Salvadori”) render claim 54 of the ‘088 patent obvious.
Both of Medline’s arguments invoke the Local Patent Rules’ requirements regarding an
accused infringer’s Final Invalidity Contentions. The Local Patent Rules require an accused
infringer’s Final Invalidity Contentions to (1) identify with particularity up to twenty-five “items
of prior art per asserted patent that allegedly invalidate[] each asserted claim,” (2) include, “for
each item of prior art, a detailed statement of whether it allegedly anticipates or renders obvious
each asserted claim,” and (3) provide “a chart identifying where specifically in each alleged item
of prior art each element of each asserted claim is found.” N.D. Ill. LPR 2.3(b)(1)–(3); see N.D.
Ill. LPR 3.1(b) (requiring a party’s Final Invalidity Contentions to include the information
required by LPR 2.3(b)). 5 Where the accused infringer contends that “a combination of items of
prior art allegedly makes a claim obvious,” it must identify “each such combination and the
reasons to combine such items.” N.D. Ill. LPR 2.3(b)(2). As of October 2018, and pursuant to
the Court’s February 2019 scheduling order, Bard was also required to limit its Final Invalidity
Contentions, “[f]or each claim alleged to be invalid, . . . to four (4) prior art grounds per claim
and four (4) non-prior art grounds,” with “each combination of references” constituting a
separate ground. N.D. Ill. LPR 3.1(b).

5

This requirement was already in place when Bard served its Final Invalidity Contentions in July 2018.
Compare N.D. Ill. General Order 18-0022, at LPR 2.3 and 3.1, with N.D. Ill. General Order 13-0004, at
LPR 2.3 and 3.1.

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 8 of 30 PageID #:10100

A.

Serany

Medline first argues that Mr. Leinsing improperly relied upon Serany for obviousness
combinations that Bard did not identify in its “Narrowing of Prior Art and Identification of
Invalidity Grounds” (the “Narrowing Disclosure”), which Bard served in April 2019 pursuant to
Local Patent Rule 3.1(b) and this Court’s February 2019 scheduling order. Doc. 226-8 at 2. In
this disclosure, Bard identified four prior art invalidity grounds for each asserted claim of the
patents-in-suit, and for each prior art invalidity ground, Bard directed Medline to the invalidity
claim charts it had provided with its Final Invalidity Contentions. None of Bard’s prior art
invalidity grounds identified Serany as a reference. In his expert report, however, Mr. Leinsing
analyzes Serany, discusses how different aspects of its disclosure purportedly show the state of
the art at the relevant time, and opines as to how Serany’s disclosures and teachings help
demonstrate that other prior art references render various claims obvious.
As already noted, Medline contends that Mr. Leinsing’s reliance upon Serany is improper
because Bard did not identify Serany as a reference in any of the prior art invalidity grounds it
identified in its Narrowing Disclosure. In response, Bard contends that it did not need to identify
Serany as a reference in its Narrowing Disclosure because Mr. Leinsing does not rely upon
Serany as part of “a prior art ground that explicitly discloses the claimed elements”; rather, he
relies upon Serany to describe background information and “to show the state of the art at the
time of alleged invention and motivation to combine prior art identified in the” Narrowing
Disclosure. Doc. 234 at 5 (emphasis omitted).
To prove that a claim would have been obvious, it is not enough for an accused infringer
to demonstrate that two or more prior art references in combination disclose all the claim’s
elements. Forest Labs., LLC v. Sigmapharm Labs., LLC, 918 F.3d 928, 934 (Fed. Cir. 2019)

8

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 9 of 30 PageID #:10101

(“An invention is not obvious simply because all of the claimed limitations were known in the
prior art at the time of the invention.”). The accused infringer generally must also show that
there was “a reason, suggestion, or motivation in the prior art that would lead one of ordinary
skill in the art to combine the references, and that would also suggest a reasonable likelihood of
success.” Id. (citation omitted); In re Cyclobenzaprine Hydrochloride Extended-Release
Capsule Patent Litig., 676 F.3d 1063, 1068–69 (Fed. Cir. 2012). A motivation or reason to
combine may be found in, among other things, prior art references or “the background
knowledge, creativity, and common sense of the person of ordinary skill.” Arctic Cat Inc. v.
Bombardier Recreational Prods. Inc., 876 F.3d 1350, 1359–60 (Fed. Cir. 2017); Plantronics,
Inc. v. Aliph, Inc., 724 F.3d 1343, 1354 (Fed. Cir. 2013).
Bard’s failure to identify Serany as a reference in its Narrowing Disclosure precludes Mr.
Leinsing from opining that Serany discloses elements of an asserted claim. See Pactiv, 2013 WL
2384249, at *3 (“To allow an expert to go beyond [a party’s Final Invalidity Contentions] would
render them useless.”). But this failure does not necessarily foreclose Mr. Leinsing from
discussing Serany with respect to other aspects of Bard’s obviousness defense, such as a
motivation to combine or a reasonable expectation of success. An obviousness “ground” based
on two or more prior art references is the “combination of references,” N.D. Ill. LPR 3.1(b),
which the Court interprets to be the combination of references that discloses all the elements of a
particular claim. Evidence showing why one of skill in the art would have combined those
references and would have reasonably expected to succeed in doing so—even if this evidence is
reflected in another prior art reference—is not itself part of the “combination[s] of references”
that Local Patent Rule 3.1(b)’s limitation on prior art grounds affects.

9

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 10 of 30 PageID #:10102

That is not the end of the inquiry, however, because Bard’s Final Invalidity Contentions
still must provide a basis for the discussion and analysis of Serany that Mr. Leinsing provides in
his expert report. See Pactiv, 2013 WL 2384249, at *3 (limiting the accused infringer’s expert to
the invalidity arguments contained in its Final Invalidity Contentions); see also Trading Techs.
Int’l, Inc. v. CQG, Inc., No. 05-cv-4811, 2014 WL 4477932, at *2 (N.D. Ill. Sept. 10, 2014)
(“Expert infringement reports may not introduce theories not previously set forth in infringement
contentions.” (citation omitted)). On this point, the Court rejects Bard’s contention that an
accused infringer’s Final Invalidity Contentions do not need to disclose prior art references that
its expert later uses to show the “state of the art.” Although some courts have followed this or
similar reasoning, see, e.g., Fujifilm Corp. v. Motorola Mobility LLC, No. 12-cv-03587-WHO,
2015 WL 757575, at *29–30 (N.D. Cal. Feb. 20, 2015) (citing cases), 6 it is the Court’s view that
an accused infringer should not be permitted to “circumvent the disclosure requirements of [this
District’s] Local Patent Rules” by offering prior art as “background” or “state of the art”
material, see Medline I, Doc. 480 at 5, 10 (prohibiting Bard from relying upon a prior art
reference “to describe the state of the art” where Bard did not disclose the reference in its Final
Invalidity Contentions); Avnet, 2016 WL 3365430, at *4; Pactiv, 2013 WL 2384249, at *2; see
also Life Techs. Corp. v. Biosearch Techs., Inc., No. C 12-00852 WHA, 2012 WL 4097740, at
*1–2 (N.D. Cal. Sept. 17, 2012) (striking expert’s references to previously undisclosed prior art
that related to “background on the art” and noting other courts’ rejections of similar “attempts to
elude patent local rules by defining materials as ‘background’ or ‘context’”). The Local Patent
Rules were designed to “avoid[] trial by ambush, stratagem, or evasion” and, just as importantly,
were “not intended to create or tolerate clever loopholes.” Wimo Labs LLC v. Polyconcept N.A,
6

The Northern District of California has local patent rules that are similar to this District’s rules. Oil-Dri
Corp. of Am. v. Nestlé Purina Petcare Co., No. 16 C 9179, 2017 WL 1862646, at *3 (N.D. Ill. May 9,
2017).

10

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 11 of 30 PageID #:10103

Inc., 358 F. Supp. 3d 761, 762–63 (N.D. Ill. 2019). Allowing an accused infringer to spring
previously undisclosed prior art analyses for the first time in an expert report under the guise of a
“background” or “state of the art” discussion creates a loophole that allows the accused infringer
to ambush the patentee in expert discovery. 7
Bard attempts to distinguish this District’s decisions in Pactiv and Avnet on the basis that
those cases did not address prior art references that “described the state of the art and provided a
motivation to combine.” Doc. 234 at 14–15. But describing the “state of the art” is essentially
providing background, and the Court does not see how a prior art reference describing the state
of the art at the time of the invention meaningfully differs from one describing the background of
the claimed invention. And that the courts in Pactiv and Avnet did not specifically address prior
art references that the accused infringer’s expert cited to provide a motivation to combine does
not diminish their underlying concern with attempts to evade the disclosure requirements of the
Local Patent Rules.
If Bard intended for its expert to rely upon Serany to provide a motivation to combine or
the state of the art with respect to any asserted claim, it had to disclose some semblance of that
reliance in its Final Invalidity Contentions. Thus, the Court must compare Mr. Leinsing’s
discussion of Serany to Bard’s analysis of Serany in its Final Invalidity Contentions to determine
if the latter provides a sufficient foundation for the former.
First, Mr. Leinsing opines that Serany is relevant to showing that Bardex, in combination
with other references, renders obvious certain claims or claim elements because Serany describes
all the equipment in the catheter tray “being organized in its order of use” and explains that the

7

This is equally true for Bard’s attempt in its Narrowing Disclosure to reserve the right to “rely upon
additional prior art references, including but not limited to the references identified in its final invalidity
contentions, to show the state of the art[, . . .] the level of skill in the art, scope of the art, and motivation
to combine.” Doc. 226-8 at 2 (emphasis added).

11

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 12 of 30 PageID #:10104

inclusion of recesses in the tray compartment to accommodate the flanges of a syringe “makes it
easy to grasp the syringe.” Doc. 234-2 ¶¶ 737, 1033, 1075, 1325, 1354; Doc. 226-15 at 3, 5;
Doc. 226-16 at 3–4; Doc. 226-18 at 3. Bard’s final invalidity claim charts for Bardex as a
primary reference, however, did not refer to Serany in any way. As such, Bard’s Final Invalidity
Contentions do not provide a basis for Mr. Leinsing’s discussion of Serany in connection with
Bardex. The Court grants Medline’s motion to strike as to this aspect of the Leinsing Report and
strikes the references to and discussions of Serany in paragraphs 737, 1033, 1075, 1325, and
1354 of the Leinsing Report, page 32 of Exhibit 4 to the Leinsing Report, pages 37 and 58 of
Exhibit 5 to the Leinsing Report, and pages 72 and 85 of Exhibit 6 to the Leinsing Report.
Second, Mr. Leinsing opines that Serany is relevant to showing that Rauschenberger, in
combination with other references, renders obvious certain claims or claim elements. Because
Bard refers to Serany on several occasions in its final invalidity charts asserting Rauschenberger
against the claims of the ‘088 and ‘761 patents, the Court must take a closer look at Mr.
Leinsing’s analysis and discussion with respect to Serany and Rauschenberger to see if they are
supported by these claim charts. 8
Recesses for a Syringe’s Flanges. Mr. Leinsing opines in the “state of the art” portion of
his report that Serany discloses a tray that is contoured to accommodate a syringe’s flanges so
that an individual can easily grasp and remove the syringe from the tray. This disclosure, he
continues, teaches and provides motivation to a person of ordinary skill in the art (“POSITA”) to
modify Rauschenberger to include one or more recesses in a tray to accommodate the flanges of
a syringe and therefore render obvious claim element 19(b) of the ‘761 patent, which requires a
compartment with “one or more recesses for accommodating flanges of one or more of the first
8

Medline did not provide the Court with Bard’s final invalidity chart asserting Rauschenberger against
the claims of the ‘596 patent, so the Court cannot compare the disclosures in that claim chart to the
Leinsing Report.

12

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 13 of 30 PageID #:10105

syringe or the second syringe,” and claim 16 of the ‘596 patent, which requires a compartment
with “one or more contours to accommodate a flange of at least one of the first syringe or the
second syringe.” Doc. 234-2 at 9–10 & ¶¶ 959, 1200; Doc. 226-9 at 76–77; Doc. 226-13 at 5;
Doc. 226-14 at 4–5.
In its final invalidity claim chart for claim element 19(b) of the ‘761 patent, Bard asserted
that it would have been obvious to modify Rauschenberger “in view of” four pieces of prior art,
including Serany, such that the tray’s first compartment had recesses to accommodate a syringe’s
flanges. Doc. 226-9 at 77–78. This assertion, however, identifies Serany as a reference to be
combined with Rauschenberger to disclose an element of a claim, which Bard’s Narrowing
Disclosure did not disclose. Bard did not specifically identify Serany as a reference that
provided the motivation to combine Rauschenberger with other references to disclose claim
element 19(b). Id. at 80–81; cf. id. at 12–13, 40–41, 49–50, 53–54 (identifying specific
references as providing a motivation to combine with respect to other claims). Accordingly,
Bard’s Final Invalidity Contentions do not disclose Mr. Leinsing’s reliance upon Serany to
provide a motivation to combine Rauschenberger with respect to claim 19 of the ‘761 patent.
The Court therefore grants Medline’s motion to strike that aspect of the Leinsing Report and
strikes the references to and discussions about Serany in paragraph 959 of the Leinsing Report
and page 25 of Exhibit 2 to the Leinsing Report.
However, Medline did not provide the Court with Bard’s final invalidity chart asserting
Rauschenberger against the claims of the ‘596 patent, so the Court does not know whether this
chart provides a sufficient basis for Mr. Leinsing’s reliance upon Serany to provide a motivation
to combine Rauschenberger with other references to disclose claim 16 of the ‘596 patent. And
the Court will not assume that the claim chart’s disclosure is inadequate. Thus, the Court denies

13

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 14 of 30 PageID #:10106

Medline’s motion to strike that aspect of the Leinsing Report, i.e., Mr. Leinsing’s references to
and discussions about Serany in paragraph 1200 of the Leinsing Report and page 31 of Exhibit 3
to the Leinsing Report. That said, the Court reiterates that Bard’s failure to identify Serany as a
reference in its Narrowing Disclosure means that Mr. Leinsing cannot opine that Serany itself
discloses the elements of claim 16 of the ‘596 patent or any other asserted claim.
Ordering Components in the Tray. Mr. Leinsing also opines in the “state of the art”
portion of his report that it was “very well-known in the art” to order the “components within a
tray in accordance with their use during a catheterization procedure,” as shown by Serany, which
teaches a tray that provides components in their preferred order of use and items arranged in a
logical step-by-step order. Doc. 234-2 at 4–5 & ¶¶ 251, 253–54. According to Mr. Leinsing,
this disclosure would have taught or motivated a POSITA to arrange items within the tray in
accordance with their use during a catheterization procedure, and it shows that a POSITA would
have had a reasonable expectation of success in doing so. Id. ¶¶ 548, 551, 563, 575, 923. Mr.
Leinsing relied upon Serany’s “ordering” teaching to opine that Rauschenberger, in view of other
references, rendered obvious claim element 1(e) of the ‘088 patent, which requires, in relevant
part, ordering the two syringes in the tray “in accordance with their use during a catheterization
procedure”; claim element 1(f), which requires the tray to have at least two compartments, with
the first compartment supporting two syringes; and claim element 1(g), which requires the first
compartment to have a base member defining “a mnemonic device indicating which of the first
syringe or the second syringe should be used first in the catheterization procedure.” Id. ¶¶ 548,
551, 563, 575; Doc. 226-6 at 15–16, 18; Doc. 226-17 at 3–5. He also opines that arranging items
in order of use, as taught by Serany, supports his opinion that Rauschenberger and other
references render obvious claim element 1(b) of the ‘761 patent, which recites “a first

14

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 15 of 30 PageID #:10107

compartment supporting a first syringe and a second syringe at different heights based upon
order of use in a Foley catheterization procedure.” Doc. 234-2 ¶ 923; Doc. 226-9 at 5; Doc. 22613 at 3.
Bard’s final invalidity claim charts for the ‘088 and ‘761 patents do not provide a basis
for these opinions. In its invalidity chart addressing elements 1(e), 1(f), and 1(g) of the ‘088
patent, Bard did not mention Serany in any respect, let alone as the source of a motivation to
combine references to arrange syringes in accordance with their order of use. True, elements
1(e), 1(f), and 1(g) also refer to element 1(b), which cites Serany in connection with placing two
syringes in the tray, with one syringe used for lubrication and one to inflate a catheter balloon,
but this citation does nothing to suggest that Bard intended to rely upon Serany to provide the
motivation to combine references that disclose the ordering of syringes in accordance with their
use during a catheterization procedure (claim element 1(e)), using one compartment to support
two syringes (claim element 1(f)), or defining a mnemonic device indicating which of two
syringes should be used first in a procedure (claim element 1(g)). As for its final invalidity chart
for claim element 1(b) of the ‘761 patent, Bard only asserted that Serany, along with other
references, demonstrated that it was well-known in the art to provide a syringe filled with
lubricant in the catheter tray and to provide a tray configured to accommodate a Foley catheter
with at least two syringes. Bard did not make any assertion suggesting that Serany’s teaching of
arranging items in the tray by order of use was relevant to the aspect of the claim element
requiring syringes to be placed at different heights in the tray. See Doc. 226-9 at 5–8, 11–16; cf.
Doc. 234-2 ¶¶ 923–24 (opinion of Mr. Leinsing that Serany’s teaching of arranging items in the
tray by order of use related to positioning the syringes at different heights in the tray based upon
order of use). Accordingly, the Court grants Medline’s motion to strike Mr. Leinsing’s reliance

15

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 16 of 30 PageID #:10108

upon Serany to supply a teaching or motivation to combine with respect to claim elements 1(e),
1(f), and 1(g) of the ‘088 patent and claim element 1(b) of the ‘761 patent and strikes the
references to and discussions about Serany in paragraphs 548, 551, 563, 575, and 923 of the
Leinsing Report, pages 12 and 22 of Exhibit 1 to the Leinsing Report, and page 10 of Exhibit 2
to the Leinsing Report.
“Ready for Use” System. Finally, Mr. Leinsing opines that Serany discloses “a system
that is ‘ready for use’ so that other parts do not have to be fetched from a storage closet” while
discussing a closed-system Foley catheter, which is “a coiled medical device including a Foley
catheter, a fluid receptacle, and a tube coupling the Foley catheter to the fluid receptacle.” Doc.
234-2 ¶¶ 620–21, 1145, 1149–50. Mr. Leinsing discusses Serany’s “ready for use” system and a
closed-system Foley catheter in relation to claim 33 of the ‘088 patent, which claims a medical
procedure kit with a “Foley catheter coupled to a fluid bag,” and claim 7 of the ‘596 patent,
which recites, in relevant part, a “coiled medical device including a Foley catheter, a fluid
receptacle, and a tube coupling the Foley catheter to the fluid receptacle.” Id.; Doc. 226-6 at 59;
Doc. 226-12 at 24; Doc. 226-14 at 3; Doc. 226-17 at 6.
Bard’s final invalidity contention argument for claim 33 of the ‘088 patent did not
specifically identify Serany as a source for the motivation to combine Rauschenberger with any
other reference to provide a Foley catheter coupled to a fluid bag. 9 Instead, Bard’s argument
merely identifies Serany as a reference to be combined with Rauschenberger—a combination
that Bard did not disclose in its Narrowing Disclosure. The Court accordingly strikes Mr.
Leinsing’s reference to and discussion about Serany’s “ready to use” system with respect to

9

The Court has also considered claim 33’s incorporation by reference of the argument and evidence for
claim 28 and claim 28’s incorporation by reference of the argument and evidence for claim 7. Bard’s
argument and evidence for these claims do not specifically identify Serany as a source for a motivation to
combine references to disclose a Foley catheter coupled to a fluid bag.

16

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 17 of 30 PageID #:10109

claim 33 of the ‘088 patent, as found in paragraph 621 of the Leinsing Report and page 32 of
Exhibit 1 to the Leinsing Report. But as already noted, Medline did not provide Bard’s final
invalidity claim chart for the ‘596 patent, so the Court cannot determine whether these
contentions provide a basis for Mr. Leinsing’s discussion of Serany’s “ready to use” system with
respect to claim 7 of the ‘596 patent. The Court denies Medline’s motion to strike that aspect of
the Leinsing Report, i.e., Mr. Leinsing’s references to and discussions about Serany in paragraph
1150 of the Leinsing Report and page 14 of Exhibit 3 to the Leinsing Report.
In sum, the Court strikes Mr. Leinsing’s references to and discussions about Serany in
paragraphs 548, 551, 563, 575, 621, 737, 923, 959, 1033, 1075, 1325, and 1354 of the Leinsing
Report; pages 12, 22, and 32 of Exhibit 1 to the Leinsing Report; pages 10 and 25 of Exhibit 2 to
the Leinsing Report; page 32 of Exhibit 4 to the Leinsing Report; pages 37 and 58 of Exhibit 5 to
the Leinsing Report; and pages 72 and 85 of Exhibit 6 to the Leinsing Report. The Court
otherwise denies Medline’s motion to strike with respect to Serany.
B.

Salvadori

Next, Medline takes issue with Mr. Leinsing’s reliance upon Salvadori to opine that
claim 54 of the ‘088 patent is obvious. Claim 54 recites “[t]he medical procedure kit of claim
45, further comprising one or more swabsticks disposed within the single layer tray.” Doc. 2266 at 97. In its Final Invalidity Contentions, Bard asserted that Rauschenberger rendered claim 54
obvious and that “[a]s shown by one or more of the following references, it was well known in
the art at the time of the alleged invention to include one or more swabsticks disposed within the
single-layer tray.” Id. at 97–98. Bard did not, however, identify Salvadori as one of these
references, nor did Bard’s claim 54 argument refer to any other claim or claim element that
disclosed Salvadori. Bard’s final invalidity chart for the ‘088 patent and the other primary

17

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 18 of 30 PageID #:10110

reference upon which Mr. Leinsing relies, Bardex, also did not refer to Salvadori with respect to
claim 54. Yet Mr. Leinsing opines in his expert report that Rauschenberger “in view of Bardex
and Salvadori,” and Bardex “in view of Salvadori,” render obvious claim 54 of the ‘088 patent.
Doc. 226-3 ¶¶ 667, 671, 854, 859; Doc. 226-17 at 7–9; Doc. 226-18 at 4–7.
Medline argues that these opinions are improper because Bard did not assert these
obviousness combinations against claim 54 of the ‘088 patent in its Final Invalidity Contentions.
The Court agrees: an expert’s report may not introduce an argument that the party did not
previously set forth in its Final Contentions. Trading Techs., 2014 WL 4477932, at *2; Pactiv,
2013 WL 2384249, at *3.
Bard does not dispute that its Final Invalidity Contentions failed to assert that the
Rauschenberger-Bardex-Salvadori and Bardex-Salvadori combinations rendered claim 54 of the
‘088 patent obvious. Bard instead argues that Mr. Leinsing’s opinion on these points is
permissible because both its Preliminary and Final Invalidity Contentions identified Salvadori as
a reference that, in combination with other references, invalidated other claims of the ‘088
patent. That is, Bard essentially contends that Mr. Leinsing can rely upon Salvadori to opine as
to the invalidity of claim 54 so long as Bard’s invalidity contentions identified that reference as
part of a combination that purportedly invalidates any other claim from the ‘088 patent, and even
if that combination differs from the combination upon which Mr. Leinsing relies. But Bard’s
position contravenes the purpose of the Local Patent Rules’ requirements regarding Final
Invalidity Contentions: to ensure that the patent owner knows precisely which combination(s) of
prior art references the accused infringer intends to assert against which claim(s) heading into
expert discovery. See N.D. Ill. LPR 2.3(b)(2), (3) (requiring the accused infringer to identify
obviousness combinations for “each asserted claim”); LPR 3.1(b) (requiring the accused

18

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 19 of 30 PageID #:10111

infringer to identify, at most, four prior art grounds “[f]or each claim alleged to be invalid,” with
“each combination of references” constituting a separate ground); Avnet, 2016 WL 3365430, at
*5 (“One of the purposes of final invalidity contentions is to give notice to plaintiffs of the
defendant’s contentions, and the bases for them, prior to expert discovery.”). To accept Bard’s
argument would strip the Final Invalidity Contentions of any meaning. See Pactiv, 2013 WL
2384249, at *3 (“To allow an expert to go beyond [a party’s Final Invalidity Contentions] would
render them useless and ignore the specificity requirements of [] Local Patent Rule 2.3.”).
Bard also points out that its Narrowing Disclosure identified Salvadori as a reference to
be combined with other references to render claim 54 of the ‘088 patent obvious. At the outset,
Bard’s identification of Salvadori in its Narrowing Disclosure as a reference to combine with
Bardex and Rauschenberger to invalidate claim 54 was improper because, as already noted, its
Final Invalidity Contention claim charts for those references did not disclose any obviousness
combinations involving Salvadori for claim 54. Adding an obviousness combination that was
not previously disclosed in a party’s Final Invalidity Contentions is the antithesis of “narrowing”
the prior art grounds at issue. 10 But even if Bard’s final invalidity charts for claim 54 of the ‘088
patent had disclosed the Rauschenberger-Bardex-Salvadori and Bardex-Salvadori obviousness
combinations upon which Mr. Leinsing relies, Bard’s Narrowing Disclosure did not identify
these precise combinations. Allowing Mr. Leinsing to now rely upon a combination of prior art
references that Bard did not choose as one of its four “prior art grounds” would defeat the
purpose of Local Patent Rule 3.1(b)’s narrowing requirement.

10

Bard attempts to blame Medline for not calling out its identification of previously undisclosed
obviousness combinations in its Narrowing Disclosure in April 2019, when Bard served the document.
Given that Medline did not know which of the identified prior art grounds Bard’s expert would opine
about until October 2020, Medline did not unduly delay in raising the issue. In any event, the Court will
not penalize Medline for Bard’s failure to comply with the ordinary meaning of a “narrowing” disclosure.

19

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 20 of 30 PageID #:10112

Ultimately, Bard’s contention is that Medline has been on notice that Bard intended to
apply Salvadori to the ‘088 patent since January 2017, when it served its Preliminary Invalidity
Contentions, and to claim 54 since April 2019, when it served its Narrowing Disclosure. But the
question is not whether Medline knew that Bard intended to rely upon Salvadori in some manner
to invalidate claim 54. The question is whether Bard’s disclosures put Medline on notice that
Bard intended to rely upon Salvadori in the manner Mr. Leinsing does in his expert report—as a
reference to be combined with Bardex or with Rauschenberger and Bardex. Bard’s Invalidity
Contentions and Narrowing Disclosure did not provide this notice.
For these reasons, the Court strikes any reference to and discussion of Salvadori in
paragraphs 322, 667–72, and 854–60 of the Leinsing Report, pages 42–44 of Exhibit 1 to the
Leinsing Report, and pages 68–71 of Exhibit 4 to the Leinsing Report. The Court also strikes the
reference to Salvadori’s disclosure of swabs or swab sticks in paragraphs 250 and 384 of the
Leinsing Report.
II.

Bard’s Motion to Strike
Bard, for its part, moves to strike two aspects of Dr. Abraham’s infringement opinion.

First, it moves to strike his opinion that Bard’s “Meter” SureStep trays infringe claim 7 of the
‘596 patent. Second, it moves to strike his opinion that Bard’s SureStep trays infringe claim 54
of the ‘088 patent.
A.

“Meter” Trays and Claim 7 of the ‘596 Patent

Bard’s first argument concerns the specificity required by the Local Patent Rules for
identifying the products the patentee accuses of infringement (the “Accused Instrumentalities”).
The Local Patent Rules require a patentee’s Final Infringement Contentions to identify,
“separately for each asserted claim, . . . each accused apparatus, product device, process, method,

20

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 21 of 30 PageID #:10113

act, or other instrumentality (‘Accused Instrumentality’) of the opposing party of which the party
claiming infringement is aware.” N.D. Ill. LPR 2.2(b); see N.D. Ill. LPR 3.1(a)(2) (requiring a
party’s Final Infringement Contentions to include the information required by LPR 2.2(a)–(h)). 11
The patentee must identify “[e]ach Accused Instrumentality . . . by name, if known, or by any
product, device, or apparatus which, when used, allegedly results in the practice of the claimed
method or process.” N.D. Ill. LPR 2.2(b).
As part of its Final Infringement Contentions, Medline identified the Accused
Instrumentalities as “Bard’s Foley catheter tray products marketed as the Bard SureStep Foley
Tray System (‘SureStep’).” Doc. 228-3 at 3; see also Doc. 228-5 at 2 (identifying the Accused
Instrumentality as “Bard’s SureStep Foley Tray System (the ‘Sure Step System’)” in its
infringement claim chart for the ‘596 patent). Medline further defined “SureStep” or the
“SureStep System” as including “catheterization systems sold in different configurations,
including but not limited to systems with drainage bags, urine meters, Foley catheters of different
sizes and/or materials, and other variations in tray contents and/or design,” and it asserted that
the Accused Instrumentalities included “all such configurations of Bard’s SureStep System”
unless otherwise noted. Doc. 228-3 at 3; Doc. 228-5 at 2 n.1. In a footnote dropped in its claim
chart for the ‘596 patent, Medline added that “the disclosures herein are exemplary and, unless
otherwise noted, are intended to illustrate where each element of each asserted claim is found
within all SureStep System products, regardless of any minor variations in tray design and/or
contents.” Doc. 228-5 at 2 n.1.

11

This requirement was already in place when Medline served its Final Infringement Contentions in July
2018. Compare N.D. Ill. General Order 18-0022, at LPR 2.2 and 3.1, with N.D. Ill. General Order 130004, at LPR 2.2 and 3.1.

21

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 22 of 30 PageID #:10114

Relevant here are Bard’s “Bag” SureStep kit and “Meter” SureStep kit. 12 The Bag kit
includes a catheter, tubing, and a fluid drainage bag; the Meter kit includes these items, as well
as a urine meter. Medline’s final infringement claim chart for the ‘596 patent includes
photographs of the Meter tray for certain claims, and it expressly refers to the Meter tray for
claim 16. But Medline’s arguments concerning claim 7 do not refer to the Meter tray, and they
only cite to photographs of the Bag tray. In his expert report and accompanying claim charts,
though, Dr. Abraham cites to photographs and diagrams of both the Bag and Meter trays or kits
to support his infringement opinions regarding claim 7. Moreover, in defining the SureStep
products accused of infringement, Dr. Abraham explained that
for the purposes of my analysis in this report, there are essentially
two tray configurations used in the SureStep products that have
been sold during the life of the patents at issue in this case. More
specifically, there are two sizes of trays. I refer to these tray
variants as the smaller and larger trays, or as the Bag and Meter
trays or Bag and Meter kits[.] . . . [T]he SureStep Bag kits and
SureStep Meter kits are representative of all of the accused
products in this case.
Doc. 228-6 ¶¶ 60–61.
Bard argues that the Court should strike the portions of the Abraham Report where Dr.
Abraham opines that the Meter tray infringes claim 7 of the ‘596 patent because Medline’s final
infringement contentions did not disclose the Meter tray as an Accused Instrumentality with
respect to claim 7. Medline responds with several arguments—none of which are persuasive.
First, Medline points out that the definition of “SureStep System” it used with its Final
Infringement Contentions encompassed all variants of the SureStep kit, including catheterization
systems with “urine meters.” That is true, but Medline’s expansive and non-limiting definition
did not identify the Meter tray or kit with the specificity required by Local Patent Rule 2.2 with
12

A kit includes, among other things, a tray. The distinction between a kit and a tray is irrelevant to the
Court’s analysis, and the Court uses kit and tray interchangeably.

22

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 23 of 30 PageID #:10115

respect to claim 7. See N.D. Ill. LPR 2.2(b) (requiring the patentee to identify the Accused
Instrumentality “separately for each asserted claim”); Medline Indus., Inc. v. C.R. Bard, Inc.
(“Medline II”), No. 14 C 3618, Doc. 481 at 4 (N.D. Ill. Jan. 8, 2020) (“A general reference to an
entire line of products, without more, falls short of [Local Patent Rule 2.2’s] requirements and
fails to provide an accused party with adequate notice as to the products in dispute.”). When
Medline served its Final Infringement Contentions, it knew about the Meter tray, as
demonstrated by Medline’s identification of it by name and its use of photographs of the Meter
tray to support its infringement arguments for claims other than claim 7. If Medline intended to
accuse the Meter tray of infringing claim 7 as well, it should have cited photographs of the Meter
tray for that claim and referred to it by name, as it did for other claims. See N.D. Ill. LPR 2.2(b)
(“Each Accused Instrumentality must be identified by name, if known[.]”); Fujitsu, 2013 WL
2300782, at *5 (“If Fujitsu Limited intended to rely on the inclusion of the LIAM-E, LRAME, or
SPM modules in the Tellabs® 7100 system for purposes of proving infringement, it should have
explicitly said so.”). Medline failed to do so. And the fact that Dr. Abraham found it necessary
(or at least prudent) to identify the Bag and Meter trays separately and cite to diagrams and
photographs of both products to opine that Bard infringes claim 7 further shows the insufficiency
of Medline’s disclosure. Cf. Medline II, Doc. 481 at 4 (“Medline’s attempt to amalgamate all
four trays is belied by [its expert’s] report, which provides separate claim charts for Tray C and
D.”).
Second, Medline contends that Bard’s non-infringement arguments regarding claim 7 of
the ‘596 patent show that Bard was on notice that the Meter tray was at issue for that claim. In
its Final Non-Infringement Contentions, Bard argued that “at least the meter tray” did not
infringe claim 7 because “the alleged fluid receptacle is not ‘between the second compartment

23

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 24 of 30 PageID #:10116

base member and the Foley catheter,’” Doc. 231-2 at 2–3, which suggests that Bard at least
suspected that the Meter tray might be in play for claim 7. But suspecting that Medline might
contend that the Meter tray infringes claim 7 and knowing for certain that Medline was making
this contention are two different things, and the rules governing Final Infringement Contentions
are intended to establish the latter. See KlausTech, Inc. v. Google LLC, No. 10-cv-05899-JSW
(DMR), 2018 WL 5109383, at *4 (N.D. Cal. Sept. 14, 2018) (“Implicit disclosures are contrary
to the purpose of the local patent rules, which require parties to ‘disclose the basis for their
contentions’ in order to ‘make them explicit and streamline patent litigation.’” (citation
omitted)).
Third, the fact that Medline’s allegations for claim 10 of the ‘596 patent purport to
illustrate infringement with a photograph of the Meter tray does not mean that Medline
sufficiently alleged that the Meter tray infringes claim 7. Even though claim 10 depends on
claim 7, they are still two separate claims, and the Local Patent Rules require the patentee to
identify “separately for each asserted claim, . . . each accused apparatus, product device, process,
method, act, or other instrumentality.” N.D. Ill. LPR 2.2(b) (emphases added); see also N.D. Ill.
LPR 2.2(c) (requiring a claim chart “identifying specifically where each element of each asserted
claim is found within each Accused Instrumentality”). To be sure, Bard may have questioned, as
the Court does, why Medline identified only Bag tray photographs for claim 7 and then switched
to a Meter tray photograph for claim 10, when the Meter tray must satisfy all the elements of
claim 7 before it can infringe claim 10. See Wahpeton Canvas Co. v. Frontier, Inc., 870 F.2d
1546, 1552 n.9 (Fed. Cir. 1989) (“One who does not infringe an independent claim cannot
infringe a claim dependent on (and thus containing all the limitations of) that claim.”); Cap Co.
v. McAfee, Inc., No. 14-cv-05068-JD, 2015 WL 4734951, at *2 (N.D. Cal. Aug. 10, 2015)

24

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 25 of 30 PageID #:10117

(“Infringement cannot be shown by a muddled hash of elements from different products[.]”).
But it was not Bard’s obligation to assume that this decision reflected Medline’s intention to
assert that the Meter tray satisfied all the elements of claim 7, especially considering the ease
with which Medline could have included photographs of the Meter tray in its chart for these
elements. Cf. MLC Intell. Prop., LLC v. Micron Tech., Inc., No. 14-cv-03657-SI, 2019 WL
1865921, at *7 (N.D. Cal. Apr. 25, 2019) (“[T]he onus is not on Micron to ‘grasp’ the scope of
MLC’s claim 45(d) [infringement] theory by piecing together bits of different contentions from
claims 30, 42 and 45, deciding on its own what is or is not a ‘scrivener’s error[.]’”).
This is not a situation where a patentee is accusing dozens of similarly functioning
products of infringement and it is burdensome and impractical for the patentee to include
evidence for each product in its claim charts. Here, there are just two products at issue: the Bag
kit and the Meter kit. There was no burden or impracticality preventing Medline from
specifically identifying the Meter kit as an Accused Instrumentality with respect to claim 7 by
including a handful of photographs showing the product and, more simply, calling it out by
name, as it had done with other claims. Its failure to do so renders Dr. Abraham’s infringement
opinions regarding claim 7 and the Meter kit improper. See Trading Techs., 2014 WL 4477932,
at *2 (“Expert infringement reports may not introduce theories not previously set forth in
infringement contentions.” (citation omitted)); Fujitsu, 2013 WL 2300782, at *4–7 (striking
portions of an expert’s infringement report that analyzed products the patentee did not identify as
being infringed in its infringement contentions). The Court, therefore, grants Bard’s motion to
strike those portions of the Abraham Report that opine that the Meter tray or kit infringes claim 7
of the ‘596 patent.

Claim 54 of the ‘088 Patent

Bard’s second argument involves the disclosure required for a patentee’s infringement
contentions regarding a particular claim. A patentee’s Final Infringement Contentions must
include a claim chart that specifically identifies “where each element of each asserted claim is
found within each Accused Instrumentality.” N.D. Ill. LPR 2.2(c).
As already noted, claim 54 of the ‘088 patent recites “[t]he medical procedure kit of
claim 45, further comprising one or more swabsticks disposed within the single layer tray.” In
its final infringement claim chart for the ‘088 patent, Medline’s argument for this claim simply
was to see “claims 45 and element 1(a) above,” i.e., see its arguments regarding claim 45 and the
first element of claim 1. Doc. 228-7 at 42. Dr. Abraham, however, provides a more detailed
explanation of Bard’s infringement of claim 54 in his expert report. He opines that “[t]he
SureStep kits contain one or more swabsticks disposed within the single layer tray,” as shown in
the two following photographs of the SureStep Bag kit and the SureStep Meter Kit:

SureStep Bag Kit

SureStep Meter Kit

Doc. 228-6 ¶ 217. Dr. Abraham further notes that the “SureStep directions for use” also
reference “swabsticks.” Id. ¶ 218.

Case: 1:17-cv-07216 Document #: 247 Filed: 01/05/21 Page 27 of 30 PageID #:10119

Bard argues that the Court should strike the portions of the Abraham Report where Dr.
Abraham opines that the swab sticks 13 from Bard’s Bag and Meter kits infringe claim 54 because
Medline’s final infringement claim chart failed to disclose this argument. Medline responds that
because its infringement argument for claim 54 directs Bard to “claims 45 and element 1(a)
above,” Bard must consider the full range of evidence that Medline incorporated by reference
from claim 45 and claim element 1(a). Claim 45 ultimately incorporates by reference argument
and evidence from four different claims—claims 1, 8, 25, and 32 14—and claim elements 1(d)(i)
and 1(d)(iii) and claim 8 include the following photograph, which shows three swab sticks like
the photographs upon which Dr. Abraham relied:

Doc. 228-7 at 7, 9–11, 15–17. Claim elements 1(a), 1(b), 1(d)(i), 1(d)(iii) and claim 8 also
include other photographs that appear to show a tray with one swab stick.
Medline’s argument is not persuasive. Initially, the Court does not see why Bard would
have looked at claim 45 (and all the claims and claim elements claim 45 ultimately incorporated

13

The Court’s use of the term “swab sticks” is not meant to suggest that the accused products have
“swabsticks” as that term is used in claim 54 and defined in the ‘088 patent.
14

Claim 45 directed Bard to claims 1 and 32 and claim elements 1(b), 1(c), and 1(d). Claim 32 crossreferenced claim 25, which simply referred to claim 1, claim 8, and claim elements 1(a), 1(b), 1(c), 1(d),
1(d)(i), and 1(d)(ii). Claim 8 told Bard to see claim 1.

by reference) to locate the swab sticks recited in claim 54. Claim 54 is a dependent claim that
adds only one element to the medical procedure kit claimed in claim 45: “one or more swabsticks
disposed within the single layer tray.” Doc. 228-6 at 7. Thus, when Medline asserted
infringement based on “claims 45 and element 1(a) above,” Doc. 228-7 at 42, it presumably
intended for Bard to look to its claim 45 arguments and evidence to address the portion of claim
54 referring to claim 45, and its claim element 1(a) arguments and evidence to address the swab
stick portion of the claim. Medline’s claim element 1(a) arguments and evidence, in turn, do
nothing to suggest that it intended to rely upon the tray’s swab sticks for any aspect of its
infringement argument. The language of claim element 1(a) (“a tray having a compartment for
receiving a medical assembly,” see id. at 2) does not refer to swab sticks, and although Medline
included a photograph of a tray that appears to hold a swab stick for that claim element, Medline
did not indicate that the swab stick was of any relevance to its infringement argument.
At any rate, even if Bard could have been expected to refer to claim 45 and then follow
the various cross-references implicated by that claim, nothing in the arguments provided by
Medline for claim 45 and the claims incorporated by reference provided any basis for Bard to
believe that Medline was relying upon the photographs showing swab sticks to prove
infringement of claim 54. None of the claims (claims 1, 8, 25, 32, or 45) recites a swab stick or
similar limitation. Nor do Medline’s infringement arguments for these claims mention swab
sticks or identify the swab sticks as being a relevant aspect of the included photographs.
Medline’s argument would allow a patentee to simply fill a claim chart with photographs
showing different aspects of the accused product without calling out which aspects of the
photographs satisfy the claim language at issue and (if not apparent) explaining why. The Local
Patent Rules demand more. See N.D. Ill. LPR 2.2(c) (requiring a claim chart “identifying

28

specifically where each element of each asserted claim is found within each Accused
Instrumentality”); Finjan, Inc. v. SonicWall, Inc., No. 17-cv-04467-BLF (VKD), 2019 WL
2077849, at *3–4 (N.D. Cal. May 10, 2019) (similar Local Patent Rule required the plaintiff to
“identify how what is shown in the image [included in a claim chart] maps to the particular claim
limitation for which the image is referenced, such as by circling or labeling in a meaningful way
the elements of the image that correspond to the limitations at issue”).
This is not “elevat[ing] form over substance,” as Medline contends. Doc. 231 at 13.
Rather, this is an example of a party using its expert to provide substance that the party omitted
from its infringement contentions—here, the contention that the swab sticks shown in certain
photographs satisfy the limitation of claim 54 that requires “one or more swabsticks disposed
within the single layer tray.” 15 Dr. Abraham cannot provide this contention for the first time in
his expert report. Trading Techs., 2014 WL 4477932, at *2; Pactiv, 2013 WL 2384249, at *3.
Accordingly, the Court grants Bard’s motion to strike those portions of the Abraham Report
where Dr. Abraham opines that the swab sticks from Bard’s Bag and Meter kits infringe claim
54 of the ‘088 patent.
CONCLUSION
For the foregoing reasons, the Court grants in part and denies in part Medline’s motion to
strike [226] and grants Bard’s motion to strike [228]. The Court strikes (1) any reference to or
discussion of Serany in paragraphs 548, 551, 563, 575, 621, 737, 923, 959, 1033, 1075, 1325,
and 1354 of the Leinsing Report, pages 12, 22, and 32 of Exhibit 1 to the Leinsing Report, pages
10 and 25 of Exhibit 2 to the Leinsing Report, page 32 of Exhibit 4 to the Leinsing Report, pages
37 and 58 of Exhibit 5 to the Leinsing Report, and pages 72 and 85 of Exhibit 6 to the Leinsing
15

Medline’s citation to documentary and testimonial evidence that purportedly shows Bard’s
acknowledgement of its swab sticks and their importance only makes the Court question why Medline did
not refer to any of this evidence in charting the infringement of claim 54.

Report; (2) any reference to or discussion of Salvadori in paragraphs 322, 667–72, and 854–60 of
the Leinsing Report, pages 42–44 of Exhibit 1 to the Leinsing Report, and pages 68–71 of
Exhibit 4 to the Leinsing Report; and (3) the reference to Salvadori’s disclosure of swabs or
swab sticks in paragraphs 250 and 384 of the Leinsing Report. The Court also strikes those
portions of the Abraham Report (including any accompanying claim charts) where Dr. Abraham
opines (1) that the Meter tray or kit infringes claim 7 of the ‘596 patent and (2) that the swab
sticks from Bard’s Bag and Meter kits infringe claim 54 of the ‘088 patent. Finally, the Court
grants Medline’s unopposed motion to seal [232].
