CIVIL ACTION NO. 2:22-cv-0343-JRG-RSP

MEMORANDUM ORDER
Before the Court is Correct Transmission’s Motion for Leave to Supplement Opening
Expert Report of Dr. Ricardo Valerdi (Dkt. No. 215.). For the reasons that follow, the motion is
DENIED.
I.

BACKGROUND
On October 22, 2023 the Court entered is Claim Construction Order. On December 15,

2023 Nokia provided non-infringement rebuttal reports. On February 7, 2024 CT served Nokia
with the proposed supplemental expert report that is the subject of this motion.
II.

APPLICABLE LAW
Fed. R. Civ. P. 16(b) provides that a schedule modification, such as permitting a

supplemental expert report, may only be made for good cause. See Reliance Ins. Co. v. Louisiana
Land & Expl. Co., 110 F.3d 253, 257 (5th Cir. 1997). In Reliance Ins. Co., the Fifth Circuit
provided that good cause may be examined under the Court’s standard four part test: “(1) the
explanation for the failure to [submit a complete report on time]; (2) the importance of the
testimony; (3) potential prejudice in allowing the testimony; and (4) the availability of a
continuance to cure such prejudice.” Id. (citing Geiserman v. MacDonald, 893 F.2d 787, 791 (5th
Cir.1990).)

III.

ANALYSIS
A. DILIGENCE
CT argues that any lack of diligence in preparing Dr. Valerdi’s supplemental report should

be placed on Nokia. (Mot. at 4-5.) CT contends that Nokia failed to properly disclose noninfringement positions until its rebuttal expert report despite on-point interrogatories, and now CT
should be permitted to respond. (Id.) In particular, CT contends that it could not prepare its doctrine
of equivalents arguments without Nokia’s non-infringement positions. (Id.) CT further contends
that because Dr. Valerdi’s supplementation is limited and merely provides specificity to previously
disclosed theories it should be permitted. (Id.)
Nokia responds that CT’s motion misconstrues the obligations around infringement
contentions and the doctrine of equivalents and is not merely a limited refinement of Dr. Valerdi’s
theories but introduces entirely new theories. (Opp. at 8-11.) Nokia contends that Dr. Valerdi’s
supplementation focuses on doctrine of equivalents arguments that were never presented in Dr.
Valerdi’s initial report. (Id. at 7-8.) Nokia further argues that it is CT’s burden to show
infringement, including under doctrine of equivalents, and thus CT should not be permitted to raise
these new theories in rebuttal to Nokia’s non-infringement arguments. (Id.) Further, Nokia
contends that it did provide a fulsome response to CT’s discovery requests and that this response
put CT on notice of Nokia’s non-infringement argument. (Id. at 9-10.)
The Court finds that CT was not sufficiently diligent in preparing its infringement report.
First, there is no dispute that a doctrine of equivalents theory of infringement is properly included
in CT’s opening infringement report. While many litigants present the doctrine of equivalents as a
response to an argument that a limitation is not literally met, this does not entitle CT to a reply
report. Second, the Court finds that Nokia’s interrogatory response as of October provided

2

sufficient disclosure of Nokia’s non-infringement contentions. 1 In this light, CT has no explanation
for its delay until February to prepare its supplemental report.
B. IMPORTANCE
CT contends its supplemental report is important as it relates to infringement. (Mot. at 6.)
Nokia contends that while this theory may be important at trial, it clearly was not important in
developing this case for trial. (Opp. at 11-12.)
The Court finds that while an infringement argument is generally important, in view of
CT’s choice to only pursue this argument on the eve of trial, this factor cannot outweigh the lack
of diligence.
C. PREJUDICE
CT contends its supplemental report will not prejudice Nokia because it merely provides
greater
specificity and CT has offered Dr. Valerdi up for a limited deposition. (Mot. at 6-7.)
.
The Court disagrees. The proposed supplementation does significantly more than offer
greater specificity. Dr. Valerdi’s opening report providing boiler plate reference to the doctrine of
equivalents does not reserve some right for CT to provide actual arguments under the doctrine
later. Moreover, a limited deposition is far from enough for Nokia to respond to Dr. Valerdi’s
doctrine of equivalents. A doctrine of equivalents argument is an infringement argument to which
Nokia would be permitted to respond, i.e. with a non-infringement report.
IV.

the above
provided
reasons,
the motion
is DENIED.

While not dispositive, the Court finds CT’s choice to not move to compel Nokia’s response to its non-infringement
contention interrogatory weighs against CT’s complaint here.
