INTRODUCTION
The plaintiff, Quest Licensing Corporation ("Quest"), filed complaints against defendants

Bloomberg L.P. and Bloomberg Finance L.P. (collectively, "Bloomberg"), Interactive Data

Corporation ("IDC"), FactSet Research Systems, Inc., and SunGard Data Systems 1 alleging
infringement of U.S. Patent No. 7,194,468 ("the '468 patent"). Presently before the court is
defendants' Motion for Summary Judgment of Non-Infringement of the '468 patent. (D.I. 193.)
For the reasons that follow, the court will grant defendants' motion for summary judgment of noninfringement of the '468 patent.

II.

BACKGROUND
Quest accuses the defendants of infringing claims 1-3, 6, 10-12, 14, 15, 26, and 29-32 of

the '468 patent. The '468 patent discloses an apparatus and a method enabling a subscriber to
receive via mobile telecommunications network information that is updated in real time such as
financial market information. Claim 1 of the '468 patent reads as follows:
Apparatus for supplying interested subscribers via a mobile telecommunications network
changing information for each of a plurality of different sets of data, the apparatus
compnsmg:
first receiving means for receiving said changing information;
second receiving means for receiving said changing information in synchronism
with said first receiving means;
a data base for storing information received by the first receiving means relating
to said different sets of data;
communication means for storing, for each interested subscriber, information
associating that interested subscriber with a corresponding group of said different
sets of data;
a subscriber profile store for storing, for each interested subscriber, information
associating that interested subscriber with a corresponding group of said different
sets of data;
means for supplying to each interested subscriber via the mobile
telecommunications network information from the data base for the
corresponding group of data sets associated in the subscriber profile store with

that interested subscriber when communication with that interested subscriber is
established; and
means for supplying from said second receiving means to each interested
subscriber via the mobile telecommunications network changing information
relating to the corresponding group of data sets associated with that interested
subscriber once said information has been supplied to that interested subscriber
from the data base.
'468 patent at 18:28-57 (emphasis added). All of the asserted claims require receiving and/or
supplying "changing information." (Id. at 18:28-24:59.)
The court issued its Order (D .I. 13 8) construing the disputed claim terms of the '468 patent
on March 11, 2016. On September 9, 2016, the defendants filed a letter request for summary
judgment with the court, seeking a judgment of non-infringement of all asserted claims. (D.I.
176.) Thecourtgranteddefendants'requestonNovember15,2016. (D.I.191.) Defendantsmove
for summary judgment of non-infringement on the grounds that the defendants' accused systems
do not receive or supply "only data that has changed" as required by all of the asserted claims of
the patent-in-suit.

STANDARD OF REVIEW
"The court shall grant summary judgment if the movant shows that there is no genuine

issue as to any material fact and that the moving party is entitled to a judgment as a matter oflaw."
Fed. R. Civ. P. 56(a). The moving party bears the burden of proving that no genuine issue of
material fact exists. Matsushita Elec. Indus. Co., Ltd. v. Zenith Radio Corp., 475 U.S. 574, 585
n.10 (1986). A fact is material if it "could affect the outcome" of the proceeding. Lamont v. New

Jersey, 637 F.3d 177, 181 (3d Cir. 2011). There is a genuine issue "ifthe evidence is sufficient to
permit a reasonable jury to return a verdict for the non-moving party." Id. When determining
whether a genuine issue of material facts exists, the district court must view the evidence in the
light most favorable to the nonmoving party and draw inferences in that party's favor. Wishkin v.
3

·Potter, 476 F.3d 180, 184 (3d Cir. 2007). If the moving party is able to demonstrate an absence
of disputed material facts, the nonmoving party must then "come forward with 'specific facts
showing that there is a genuine issue for trial."' Matsushita, 475 U.S. at 587 (citing Fed. R. Civ.
P. 56(e)) ..
The mere existence of some evidence in support of the nonmoving party will not be
suffi.eient for denial of a summary judgment motion. Anderson v. Liberty Lobby, Inc., 477 U.S.
242, 249 (1986). Rather, the nonmoving party must present enough evidence to enable a jury to
reasonably find for it on that issue. Id. The party opposing summary judgment must present more
than just "mere allegations, general denials, or ... vague statements" to show the existence of a
genuine issue. Quiroga v. Hasbro, Inc., 934 F.2d 497, 500 (3d Cir. 1991). As such, a nonmoving
party must support their assertion that a material fact is in dispute by: "(A) citing to particular parts
of materials in the record, including depositions, documents, electronically stored information,
affidavits or declarations, stipulations (including those made for purposes of the motion only),
admissions, interrogatory answers, or other materials"; or "(B) showing that the materials cited do
not establish the absence or presence of a genuine dispute, or that an adverse party cannot produce
admissible evidence to support the fact." Fed. R. Civ. P. 56(c)(l). The moving party is entitled to
judgment as a matter of law if the nonmoving party fails to make· a sufficient showing on an
essential element of its case for which it has the burden of proof. Celotex, 477 U.S. at 322.
IV.

DISCUSSION
A. Patent Infringement Standard
A patent is infringed when a person "without authority makes, uses or sells any patented

invention, within the United States ... during the term of the patent." 35 U.S.C. § 271(a). A
patent infringement analysis entails two steps: "(1) claim construction to determine the scope of
the claims, followed by (2) determination of whether the properly construed claim encompasses
4

the accused device." Bai v. L & L Wings, Inc., 160 F.3d 1350, 1353 (Fed. Cir. 1998) (citations
omitted). The first step, clailn construction, is a matter of law for the court to decide. Markman

v. Westview Instruments, Inc., 517 U.S. 370, 372 (1996). The second step, the determination of ·
infringement, is a question of fact. Bai, 160 F.3d at 1353. "Literal infringement of a claim occurs
when every limitation recited in a claim appears in the accused device, i.e., when 'the properly
construed claim reads on the accused device exactly."' KCJ Corp. v. Kinetic Concepts, Inc., 223
F.3d 1351, 1358 (Fed. Cir.2000) (citation omitted). The patent owner has the burden of proving
infringement and must meet its burden by a preponderance of the evidence.

SmithKline

Diagnostics, Inc. v. Helena Lab. Corp., 859 F.2d 878, 889 (Fed. Cir. 1988) (citations omitted).

B. Disputed Limitation: "Changing [Price] Information"
Summary judgment of non-infringement is appropriate because Quest has not identified a
genuine issue of material fact regarding the limitation "changing information." Under the court's
construction, the term "changing information" means "only [price] data that has changed." (D.I.
13 8 at 1.) In support of its motion, Defendants argue that it is undisputed that defendants' accused
systems receive and supply transaction information-such as stock trades, bids and quotes-that
always includes non-changing information such as the stock symbol. (D.I. 194 at 11.) On the
other hand, Quest contends that there is a material factual dispute as to whether sending nonrepeating price data along with a ticker symbol (or other identifier) is within the scope of the
claims. (D.I. 207 at 16.) Quest argues, that under the court's construction of "changing [price]
information," the attachment of the stock symbol or other identifier does not preclude a finding of
infringement. (D.I. 207 at 1.)

5t--

The court agrees with the defendants. Initially, for the first time in the proceedings, Quest
1

contends that stock symbols are "changing information." (D.I. 208 at 2.) This assertion flies

5

directly in the face of the court's claim construction. (Id.) The court has construed the term
"changing information" to mean "only [price] data that has changed." (D.I. 138.) In its Order
construing this limitation, the court stated the following:
The plaintiff seeks plain and ordinary meaning, or "information subject to
change over the course of a period of time." The court rejects this definition for
two reasons. First, as the defendants note, the specification emphasizes
conservation of bandwidth as central to this invention. See 468 patent at 1:2327. By sending updates that include only changed information, the system can
accomplish this goal. 468 patent at 2:29-39, 13: 18-23. Second, the plaintiffs
own statements to the Patent Trial and Appeal Board ("PTAB") support the
defendants' construction. In its Preliminary Response to the Covered Business
Method Patent Review ("CBMR"), the plaintiff stated that the "claims also
provide for an apparatus whereby only changed information of interest to the
subscriber is sent to that subscriber's mobile device." (D.I. 123 at ASS
(emphasis in original).) The court declines to construe this term inconsistently
with the explanation the patent owner provided to the PTAB.
(Id. at 1 n.2.}

Quests seeks to avoid the consequences of its own statements, both in the '468 patent
specification and before the PTAB, with the accusation that "the Court narrowed the meaning of
'changing information' at Markman when it adopted defendants' construction." (D.I. 207 at 8-9.)
This is a new argument that is unavailing for the reasons set forth in the court's order. Quest's
answering brief barely touches on the issues raised by the defendants. Instead, Quest spends
substantial portions of its brief attempting to persuade the court to revisit its claims construction
ruling. Quest does not dispute that defendants' accused systems receive and send the stock symbol
every single time the systems receive data from the exchanges or supply data to mobile users.
Given this fact and the record evidence, the court finds, as a matter oflaw, that defendants' accused
systems receive and supply financial exchange transaction information that always includes a

6

unique identifier that does not change (e.g., stock symbol). (D.I. 196, Miller Deel. (Bloomberg)
at~ 3-4; D.I. 197, Batten Deel. (IDC) at~~ 4-5; D.I. 198, Russell Deel. (Schwab) at~~ 3-4.) 2

Quest argues there is a difference in expert opinion between Quest's expert, Dr. Nathaniel
Polish ("Dr. Polish"), and defendants' experts, Dr. Art Brody and Dr. Vijay Madisetti, as to
whether sending a ticker symbol as part of a data packed with a changed price constitutes "only
data that has changed." (D.I. 207 at 17.) Quest cites Leader Techs., Inc. v. Facebook as persuasive
authority that supports its view that this difference sets up a dispute of material fact. C.A. No. 09862-LPS, 2011 WL 1514701, at *2 (D. Del. Mar. 14, 2011) (holding that "[t]he expert witnesses.
. . advanced detailed and plausible, but conflicting, opinions concerning the application of the
Court's claim construction to the accused device for infringement purposes" sufficient to "preclude
summary judgment"). Unlike Leader, here, a classic battle of the experts is not extant. Quest's
expert failed to apply the court's claim construction. In his expert report, Dr. Polish stated that
defendants' accused systems receive "real-time changing data" from exchanges or "real time feeds
from exchanges" and that those systems supply "real-time information"-to the mobile users. (D.I.
194, Ex. 5 ~~ 45, 73; Ex. 6 ~ 46, 48, 69; Ex. 7 ~~ 47, 73.) This opinion ignores the court's use of
the word "only" in its construction of "changing information." This lack of attention to the court's
legal determination is disqualifying. Dr. Polish's new declaration is similarly unhelpful to Quest
and equally lacking in the force needed to fend off the entry of summary judgment.

See

TechSearch, L.L.C. v. Intel Corp., 286 F.3d 1360, 1372 (Fed. Cir. 2002) ("conclusory statements
are insufficient to shoulder the non-movant's burden"); Aristocrat Techs. Australia Pty Ltd V

2
Quest does not contest this fact in its answering brief or cite any materials in the record to contradict this
finding. In fact, for Bloomberg and Schwab, Quest's expert has admitted that non-changing ticker symbols are
always included every time the price information is communicated. See, e.g., D.I. 195, Ex. 5, Polish Bloomberg
Report at if74 ("the price information includes a timestamp that is associated with the prices and ticker symbols that
gets transmitted every time price information is communicated."); Ex. 7 ("the price information includes a
timestamp that is associated with the prices and ticker symbols in the same data structure for the real time data
transmission.").

Int'! Game Tech., 709 F.3d 1348, 1360-61 (Fed. Cir. 2013) (expert's conclusory declaration was

not useful).

Accordingly, summary judgment is appropriate, and the court will grant the

defendants' motion.

V.

CONCLUSION
For the reasons stated above, the defendants' motion for summary judgment of non-

infringement of all asserted claims of the patent-in-suit will be granted.
