On February 12, 2018, Plaintiff Avocent Huntsville, LLC filed a motion for leave to serve
supplemental infringement contentions pursuant to Patent L.R. 3-6. (Pl.’s Mot., Dkt. No. 63.)
On April 5, 2018, the Court held a hearing, and, for the reasons set forth below, DENIES
16
Avocent’s motion for leave to serve supplemental infringement contentions, because it lacks good
17
cause at this juncture.

I.
BACKGROUND
On July 28, 2017, Plaintiff Avocent Huntsville LLC (“Avocent”) brought this action
20
against Defendant ZPE Systems, Inc. (“ZPE”) alleging that ZPE’s products, including the
21
NodeGrid Serial Console, infringe two of Avocent’s patents, U.S. Patent Nos. 7,853,682 (“the
22
‘682 Patent”), and 7,478,152 (“the ‘152 Patent”), both titled “System and Method for
23
Consolidating, Securing and Automating Out-of-Band Access to Nodes in a Data Network.”
24
Avocent and ZPE both sell computer network management appliances.
25
Pursuant to Patent Local Rule 3-1, Avocent served its Infringement Contentions on
26
November 22, 2017. On December 5, 2017, ZPE asserted that Avocent’s charts failed to address
27
the claimed network node claim limitation and demanded a meet and confer to discuss the alleged
28
deficiencies in Avocent’s infringement contentions. (Decl. of James Berquist, “Berquist Decl.,”
1
Dkt. No. 63-1 ¶ 6.) That meet and confer was conducted telephonically on December 8, 2017.
2
(Berquist Decl. ¶ 7.) Thereafter, on January 19, 2018, Avocent served supplemental infringement
3
contentions, but did not seek leave to court before doing so. (Pl.’s Mot. at 1.) ZPE brought this to
4
the district court’s attention on January 24, 2018. (Berquist Decl. ¶ 11.)
5
On February 12, 2018, Avocent filed the instant motion for leave to serve supplemental
6
infringement contentions. (Pl.’s Mot., Dkt. No. 63.) On February 26, 2018, ZPE filed an
7
opposition. (Def.’s Opp’n, Dkt. No. 72.) On March 5, 2018, Avocent filed a reply. (Pl.’s Reply,
8
Dkt. No. 73.)

LEGAL STANDARD
“The Northern District of California has adopted local rules that require parties to state
United States District Court
Northern District of California
11
early in the litigation and with specificity their contentions with respect to infringement and
12
invalidity.” O2 Micro Int'l Ltd. v. Monolithic Power Sys., Inc., 467 F.3d 1355, 1359 (Fed Cir.
13
2006). The patent local rules provide “for a streamlined mechanism to replace the series of
14
interrogatories that accused infringers would likely have propounded in [their] absence” and are
15
“designed to require parties to crystallize their theories of the case early in the litigation and to
16
adhere to those theories once they have been disclosed.” DCG Sys. v. Checkpoint Techs., LLC,
17
No. C 11-03792 PSG, 2012 WL 1309161, at *2 (N.D. Cal. Apr. 16, 2012) (quotations and
18
footnote omitted); O2 Micro Int'l Ltd. 467 F.3d at 1366 n.12 (quoting Nova Measuring
19
Instruments Ltd. v. Nanometrics, Inc., 417 F. Supp. 2d 1121, 1123 (N.D. Cal. 2006)).
20
Patent Local Rule 3-1 requires a party claiming patent infringement to serve on all parties a
21
disclosure of asserted claims and infringement contentions. Pursuant to that local rule, the
22
infringement contentions must contain (a) each claim of each patent that is allegedly infringed by
23
each party, (b) all accused instrumentalities for each asserted claim, (c) a chart identifying
24
specifically where each limitation of each asserted claim is located within each accused
25
instrumentality, (d) a description of the acts of the alleged indirect infringer that induced the direct
26
infringement by a third party, (e) whether each limitation of each asserted claim is alleged to be
27
literally present or present under the doctrine of equivalents in the accused instrumentality, (f) the
28
priority date to which each asserted claim allegedly is entitled if applicable, (g) an identification of
2
1
each apparatus that practices the claimed invention if applicable, and (h) the basis for the party's
2
allegation of willful infringement if applicable. Patent L.R. 3-1.
3
A party may amend its infringement contentions “only by order of the Court upon a timely
4
showing of good cause.” Patent L.R. 3-6. Non-exhaustive examples of circumstances that may,
5
absent undue prejudice to the non-moving party, support a finding of good cause include: (1) an
6
adverse claim construction; (2) recent discovery of material prior art despite an earlier diligent
7
search; and (3) recent discovery of nonpublic information about the accused product that, despite
8
diligent efforts, was not discovered before service of the infringement contentions. Id.
9
10
III.
DISCUSSION
Plaintiff seeks to amend its infringement contentions, which it believes comported with
United States District Court
Northern District of California
11
Patent L.R. 3-1, because ZPE asserted they were insufficient based on differing claim construction
12
language. (Pl.’s Mot. at 5-6.)
13
Defendant contends that Plaintiff has not demonstrated good cause, because it ignored
14
ZPE’s repeated requests for details regarding how the network nodes claim limitation was met.
15
(Def.’s Opp’n at 7.)
16
The good cause analysis proceeds in two steps: “first, the court must determine whether the
17
moving party was diligent in amending its contentions; second the court must determine whether
18
the non-moving party would suffer undue prejudice if the motion to amend were granted.” DCG
19
Sys., 2012 WL 1309161, at *3. “If the court finds that the moving party was not diligent in
20
amending its infringement contentions, there is no need to consider the question of prejudice to the
21
non-moving party, although a court in its discretion may elect to do so.” Apple Inc. v. Samsung
22
Elecs. Co., No. CV 12-00630 LHK, 2012 WL 5632618, at *2 (N.D. Cal. Nov. 15, 2012)
23
(footnotes omitted).
24
A.
25
“[T]he diligence required for a showing of good cause has two phases: (1) diligence in
Diligence
26
discovering the basis for amendment; and (2) diligence in seeking amendment once the basis for
27
amendment has been discovered.” Positive Techs., Inc. v. Sony Elecs., Inc., No. C 11-2226 SI,
28
2013 WL 322556, at *2 (N.D. Cal. Jan. 28, 2013). “The burden is on the movant to establish
3
1
diligence rather than on the opposing party to establish lack of diligence.” Radware Ltd. v. F5
2
Networks, Inc., No. C-13-02021-RMW, 2014 WL 3728482, at *1 (N.D. Cal. July 28, 2014). “In
3
considering the party’s diligence, the critical question is whether the party could have discovered
4
the new information earlier had it acted with the requisite diligence.” Id.
5
Plaintiff claims that it was diligent in providing the additional detail after the December 8,
6
2017 meet and confer, because it sent ZPE amended infringement contentions on January 19,
7
2018, rather than delaying disclosure until after leave could be granted. (Pl.’s Mot. at 7.) The
8
Court notes, however, that Avocent did not seek leave of court for several weeks when, on
9
February 12, 2018, it finally filed the instant motion.
10
Defendant argues that Plaintiff’s proposed amendments constitute an attempt to address
United States District Court
Northern District of California
11
ZPE’s non-infringement theory that a claim limitation has gone unaddressed. (Def.’s Opp’n at 6.)
12
ZPE contends that courts in this district have routinely denied motions for leave to amend
13
infringement contentions on the grounds that patentees may amend their infringement contentions
14
to respond to non-infringement positions taken by an opposing party. Id. at 6-7. Defendant cites to
15
Verinata Health, in which the Court concluded that the plaintiff’s surprise by defendant’s
16
noninfringement theories was insufficient to meet the good cause burden. Verinata Health, Inc. v.
17
Ariosa Diagnostics, Inc., 236 F. Supp. 3d 1110, 1114–15 (N.D. Cal. 2017)(“Illumina's proposed
18
amendments are merely responsive to Ariosa's noninfringement contentions rather than raising
19
theories based on previously unknown information.”); see also Finjan, Inc. v. Symantec Corp.,
20
2017 WL 4025219, at *3 (N.D. Cal. Sept. 13, 2017). Had Illumina identified new nonpublic
21
information that led to its proposed amendments, it may have shown good cause to amend its
22
infringement contentions. Verinata Health, 236 F. Supp. 3d at 1115. This case is factually distinct
23
because ZPE made no additional noninfringement disclosures in the two months between the
24
service of the original and supplemental infringement contentions. (Pl.’s Reply at 6.)
25
Here, instead, Avocent claims that its original infringement contentions were sufficient,
26
and that it is only seeking leave to amend to satisfy ZPE’s criticisms of the original contentions.
27
(Pl.’s Mot. at 7; Pl.’s Reply at 7.) Thus, the basis for discovering the asserted need for amendment
28
was through the meet and confer efforts which alerted Avocent to the parties differing claim
4
1
construction definitions. (See Pl.’s Reply at 8-9.) Even in its reply, Avocent contends that it has
2
not changed its infringement theory and “that the additional information supplemented Avocent’s
3
earlier disclosure” in an effort to counter ZPE’s claim construction. (Pl.’s Reply at 9-10.) To the
4
extent that Plaintiff is attempting to only add clarifying information regarding the accused
5
products, such information may be provided in conjunction with the claim construction process.
6
Thus, this is not a sufficient basis for amendment, particularly given that Avocent is essentially
7
conceding that it had all of the pertinent information at the time it served its original infringement
8
contentions. That ZPE was allegedly threatening to move to strike the original contentions is of
9
no consequence, as no such motion was filed. (Pl.’s Mot. at 6; Pl.’s Reply at 11.) Thus, Plaintiff’s
reliance on Monolithic Power Sys., Inc. v. Silergy Corp., 2015 WL 5440674, in which the
11
United States District Court
Northern District of California
10
infringement contentions were stricken, is misplaced. (Pl.’s Reply at 11.) While the undersigned
12
has no doubt that Avocent supplemented its infringement contentions in good faith reliance on
13
ZPE’s representation that the failure to supplement would result in a motion to strike, that,
14
unfortunately, does not give rise to good cause.
15
Since good cause does not exist, the undersigned need not address the second part of the
16
diligence inquiry. Thus, the first prong of the good cause analysis set forth in Patent Local Rule 3-
17
6 is not satisfied. This, however, does not necessarily prevent Avocent from seeking leave to
18
amend its infringement contentions post-claim construction should the district court adopt ZPE’s
19
proposed construction. See Patent L.R. 3-6(a).
20
B.
Undue prejudice
21
The second prong of the good cause analysis requires the court to consider "whether the
22
non-moving party would suffer undue prejudice if the motion to amend were granted." DCG Sys.,
23
2012 WL 1309161, at *3. Since the first prong of the good cause analysis is not satisfied, the
24
Court need address whether Defendant would be unduly prejudiced.
25
C.
26
The undersigned is concerned that the parties have not sufficiently met and conferred in
Meeting and Conferring and Professional Conduct
27
connection with this motion. While ZPE claims to be a small company with limited financial
28
resources, it appears to have created unnecessary motion practice through its refusal to stipulate to
5
1
amending the infringement contentions despite having requested that they be supplemented and
2
participating in the December 8, 2017 meet and confer.1 At the hearing, Plaintiff’s counsel stated
3
that ZPE threatened a motion to strike, and that he believed that the supplemental contentions,
4
which were costly to amend, resulted in that motion not being filed. Given the apparent tenor of
5
the meet and confer, and that no motion to strike was filed, the Court finds Plaintiff’s
6
representation credible, and is concerned with the gamesmanship that seems to have occurred.
The parties are reminded of their obligation to meet and confer in good faith and stipulate
7
8
whenever possible to avoid further unnecessary motion practice, which gives rise to an
9
unnecessary expense to the parties and a waste of judicial resources. The parties are directed to
review the Northern District’s Guidelines for Professional Conduct, which should aid them in their
11
United States District Court
Northern District of California
10
future interactions. (Available at: https://cand.uscourts.gov/professional_conduct_guidelines).
12
IV.
For the reasons set forth above, the undersigned DENIES Plaintiff’s motion for leave to
13
14
serve supplemental infringement contentions.
IT IS SO ORDERED.

ZPE’s local counsel Scott Kolassa, who attended the hearing, did not participate in the meet and
confer efforts, which were conducted by lead attorney Robert Whitman. Mr. Kolassa represented
that he attended the hearing, so his client would not incur the travel costs associated with Mr.
Whitman’s attendance. Mr. Whitman, however, could have appeared by telephone pursuant to the
undersigned’s “Procedures for Telephonic Appearances” (available at:
https://cand.uscourts.gov/kaworders). Mr. Whitman’s absence meant that the Court did not have
the benefit of his interpretation of the meet and confer discussions, and must give more weight to
Plaintiff’s counsel’s understanding of what transpired.
