`
`INTRODUCTION
`
`Plaintiff Mobile Telecommunications Technologies, LLC’s (“MTel’s”) proposed
`
`constructions for the claim terms of U.S. Patent Nos. 5,809,428 (the “’428 Patent”), 5,754,946
`
`(the “’946 Patent”), 5,894,506 (the “’506 Patent”), 5,590,403 (the “’403 Patent”), 5,659,891 (the
`
`“’891 Patent”), 5,915,210 (the “’210 Patent”) and 5,786,748 (the “’748 Patent”) (collectively, the
`
`“Patents-in-Suit”) follow the canons prescribed by the Federal Circuit. MTel’s constructions are
`
`consistent with the intrinsic and extrinsic evidence and provide meanings that the jury will
`
`understand. A person having ordinary skill in the art (PHOSITA) at the time each invention was
`
`made would have understood MTel’s constructions as correct. On the other hand, Defendants’
`
`proposed constructions inject structural limitations into the claims, read preferred embodiments
`
`out of the claims, and contradict the claim language. Defendants’ proposals are contrived to
`
`avoid infringement and are otherwise unsupported by black letter law.
`
`II.
`
`STANDARDS OF CLAIM CONSTRUCTION
`
`“Claim construction is a matter of resolution of disputed meanings and technical scope, to
`
`clarify and when necessary to explain what the patentee covered by the claims, for use in
`
`determination of infringement.” U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1568 (Fed.
`
`Cir. 1997). The words of a claim are presumed to use their ordinary and customary meaning,
`
`which “provides an objective baseline from which to begin claim interpretation.” Phillips v.
`
`AWH Corp., 415 F.3d 1303, 1312-1313 (Fed. Cir. 2005) (“[a] fundamental maxim is that the
`
`words in a claim should be given their ordinary meaning”). The ordinary and customary
`
`meaning “is the meaning that the term would have to a PHOSITA at the time of the invention.”
`
`Id. at 1303.
`
`There are only two exceptions to the general rule that claim terms are given their plain
`
`and ordinary meanings: “1) when a patentee sets out a definition and acts as his own

`
`
`
`lexicographer, or 2) when the patentee disavows the full scope of a claim term either in the
`
`specification or during prosecution.” Thorner v. Sony Computer Entm’t Am. LLC , 669 F.3d
`
`1362, 1365 (Fed. Cir. 2012). The purpose of claim construction is to define the proper scope of
`
`the invention and to give meaning to claim language when the jury might otherwise
`
`misunderstand a claim term in the context of the patent and its file history.1 See, e.g., i2 Techs.,
`
`Inc. v. Oracle Corp., No. 6:09-cv-194, 2011 WL 209692, at *4 (E.D. Tex. Jan. 21, 2011) (“The
`
`plain language of the term is understandable; therefore, [the disputed terms] do not require
`
`construction.”). If a claim term is non-technical and derives no special meaning from the patent
`
`and its prosecution history, then the Court has no need to function as a thesaurus. See Brown v.
`
`3M, 265 F.3d 1349, 1352 (Fed. Cir. 2001) (concluding that non-technical terms of art . . . do not
`
`require elaborate interpretation).
`
`III. OVERVIEW OF THE PATENTS-IN-SUIT
`
`The inventors, Dennis W. Cameron, Walter C. Roehr, Jr., Rade Petrovik, Jai P. Bhagat,
`
`Masood Garahi, William D. Hays, and others, filed these patents between November 12, 1992
`
`and February 28, 1997. Each inventor worked at or with Mobile Telecommunications
`
`Technologies Corp., in Jackson, MS, the predecessor-in-interest of MTel. The company owned
`
`and operated the first commercially available, two-way wireless messaging network in the
`
`country, known as the Skytel paging network. Today, the Skytel paging network is still in
`
`operation and is used by first responders and medical professionals because of its reliability.
`
`The ’428 Patent incorporates by reference the entirety of the ’946 Patent (’428 at [1:39]).
`
`The ’946 Patent is a continuation-in-part (CIP) of U.S. Patent. No. 5,590,403.

`
`Case 2:12-cv-00832-JRG-RSP Document 103 Filed 02/06/14 Page 7 of 32 PageID #: 2103
`
`
`
`A. The Inventions Described and Claimed in the ’428 Patent.
`
`The ’428 Patent teaches a system for reducing the errors that once plagued wireless data
`
`communications: undelivered messages. Previously, a mobile unit could only acknowledge that
`
`it had accurately received a message. The acknowledgment, however, did not tell the network
`
`whether the mobile unit had received: (1) the actual message (“Honey, I’ll be home for dinner”);
`
`or (2) a probe message (a message sent to determine whether an address can be reached). The
`
`’428 Patent enables a mobile unit to distinctively acknowledge whether a successfully delivered
`
`message was a data message or a probe message.
`
`Prior to the ’428 Patent, messages that could not be delivered immediately might be lost,
`
`never to be delivered unless the sender sent the message again. The ’428 Patent allows
`
`undelivered messages to be stored for processing or delivery later.
`
`B.
`
`The Inventions Described and Claimed in the ’946 Patent.
`
`Mobile units receive messages. Many messages are automatically sent if the mobile unit
`
`does not acknowledge receipt of the complete message. This compounds message traffic on the
`
`network, reducing capacity and decreasing quality of service. Even still, some errors are not
`
`corrected automatically. In addition, sometimes a portion of a message is not received and needs
`
`to be resent, refreshed, completed, or updated. ’946 Patent at [17:20-21] (“message or a partial
`
`message to be retransmitted”)). At times, a user may wish to have additional pages of an article,
`
`or to open photos or attachments, or to have items updated. The ’946 Patent solves these
`
`problems while eliminating network congestion (and increasing capacity) due to unnecessary
`
`automatically sent messages. The ’946 Patent teaches allowing a user to request that the network
`
`send the part of the message not previously received. If the user does not request the rest of the
`
`message, it is not sent. Id. at 17:6-7 (“indicates that the message has not been completely or
`
`properly received”).

`
`
`
`The ’946 Patent enables a user to transmit a signal indicating that the mobile unit wants
`
`something sent, typically a part of a message that was not received. The network then sends the
`
`requested part of the message to the mobile unit. The invention increases efficiency and lowers
`
`costs by allowing the user the flexibility to elect not to request transmission of unneeded portions
`
`of messages. Id. at 17:24-27.
`
`C.
`
`The Inventions Described and Claimed in the ’891 Patent.
`
`The ’891 Patent describes and claims methods for operating more than one carrier in a
`
`channel to achieve higher capacity at a range of operating parameters, without undue interference
`
`protection. ’891 at [2:15-25]. Transmissions occur in channels, and multicarrier modulation
`
`enables efficient use of limited frequency bandwidth available. To avoid interference caused by
`
`signals straying between channels, signals are confined by emissions masks.
`
`The ’891 Patent discloses a method that includes operating multiple carriers in a channel
`
`using inventive parameters. Specifically, the difference between the center frequency of the
`
`outer most carriers within the channel and the edge of the mask that defines the channel has to be
`
`more than half the frequency difference between the center frequencies of each adjacent carrier.
`
`Id. at [4:12-34].
`
`Below, Fig. 3B illustrates a channel defined by a mask. 32a and 32b are overlapping
`
`carriers within the channel. The frequency differences between the center frequency of carrier
`
`32a and 32b (the dashed lines) and the nearest band edge of the mask is greater than half the
`
`frequency difference between the center frequencies of carriers 32a and 32b. Id. at [4:24-34].

`
`The Inventions Described and Claimed in the ’506 Patent.
`
`The inventions of the ’506 Patent save time for users and save capacity for networks.
`
`’506 at [1:40]. The ’506 teaches a way to use symbols, thoughts, and phrases as canned
`
`messages. Emoticons are an example: when a smartphone user types a colon and a closed
`
`parenthesis (or “:)”) the recipient message recipient sees a happy face: .
`
`The ’506 Patent teaches the use of a file of canned messages and a corresponding file of
`
`message codes. Each canned message is retrievable using its corresponding code. Id. at [1:55-
`
`57]. The network and the mobile units can each have a file of canned messages and a
`
`corresponding file of message codes.
`
`The canned message or code files on a mobile unit may be updated from files stored on
`
`the network. That way updated canned message files on the network can be used by all the
`
`network users. But files on a network may also be updated from the subscriber terminal (mobile
`
`unit). For example, interest groups may have their own customized canned messages. Id. at
`
`[2:1-6].
`
`Canned messages can accommodate multiple response options. Id. at [2:13-27]. For
`
`example, a “Calendar” invite is a canned message that can accommodate multiple optional
`
`responses; the recipient of a calendar invite can optionally respond with: “accept,” “decline,”
`
`“tentative,” or the recipient may be allowed to suggest a time or date. In addition, the canned

`
`
`
`messages may be phrased to accept the addition of one or more parameters, which may be filled
`
`in by the sender. A canned message with parameters might be, for example, “Call me at _:__ at
`
`(___) ___-_____.” The sending party may want the receiving party to call at “4:00 p.m.” at
`
`phone number (512) 512-1212. Thus, the canned message prompts the sending party to fill-in
`
`two parameters: time and phone number.
`
`E.
`
`The Inventions Described and Claimed in the ’403 Patent.
`
`The ’403 Patent describes and claims methods for transmitting information and
`
`communicating messages in a two-way wireless data communication network. ’403 at [1:9-14;
`
`33:10-34:63]. One method is to transmit information to a mobile device using two or more sets
`
`of transmitters during two or more time periods. Id. at [33:10-34: 34]. During the first period,
`
`the sets of transmitters transmit in simulcast a block of information, which means they transmit
`
`the same information at the same time. Simulcast transmission increases the chances that the
`
`information will be received by a mobile device. Id. at [4:54-58]. During a second time period,
`
`the sets of transmitters transmit different blocks of information. Id. at [5:11-28]. The techniques
`
`of the ’403 Patent increase coverage and throughput. Id. at 4:44-48].
`
`The ’403 Patent also describes and claims “zone dithering.” Transmitters cover an area
`
`called a “zone.” Fig. 25 (right) shows a blue
`
`Zone 1 and a red Zone 2. The transmitters
`
`(the Xs 2512, 2514, and 2516) are normally
`
`in Zone 1 (shown by the solid blue line), but
`
`can instead be assigned to an expanded Zone
`
`2 (dashed red line). Zone dithering is the
`
`process of assigning transmitters either to Zone 1 or to Zone 2 dynamically to meet the demands
`
`for network services. Id. at [10-11, 4:60-5:3]. Zone dithering assigns transmitters into zones in

`
`response to the level of mobile data traffic, or in response to interference. Id. at [5:65-6:23]. In
`
`Fig. 25, the mobile devices (the Rs) that had previously been in an area of interference are shown
`
`in purple.
`
`F.
`
`The Inventions Described and Claimed in the ’210 Patent.
`
`The ’210 Patent is a continuation of the ’403 Patent. The ’210 Patent describes and
`
`claims transmitting information and communicating messages in a multi-carrier simulcast
`
`system. ’210 at [5:25-40; 33:45-34:44]. Multi-carrier simultaneous transmission allows for high
`
`transmission rates because multiple unique data streams are sent at the same time. Id. at [13:3-
`
`14; 48-49]. The ’210 Patent discloses a system in which a second transmitter simulcasts with a
`
`first transmitter, but is spatially separated from the first. Id . at [33:56]. Both transmitters
`
`generate multiple carrier signals within the selected frequency band—at substantially the same
`
`frequencies as each other. Id. at [5:25-40].
`
`The ’210 Patent Fig. 9 (below) illustrates eight multiple carriers 904 . . . 932, each of
`
`which can be modulated to carry a data stream. Id. at [13:3-14, 48-49].

`Apple’s Proposal
`
`Samsung’s Proposal
`
`“probe

`
`No construction necessary;
`plain and ordinary meaning.
`
`’428 Patent,
`Claim 1
`
`
`
`A message sent by
`the network
`operation center to
`locate a mobile unit
`
`
`
`Same as Apple
`
`The plain and ordinary meaning of “probe message” is clear from the context of the
`
`Claim, which is a message that is sent to determine whether an address can be reached. See Exh.
`
`1, Newton’s TeleCom Dictionary, 11th Ed., 481 (1996) (defining “Probe” as “an empty message
`
`that is sent to reach a particular address to determine if an address can be reached”). Defendants
`
`propose adding “locate,” which improperly imports a limitation from the Specification into the
`
`Claims. See Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005) (“[A]lthough the
`
`specification often describes very specific embodiments of the invention, we have repeatedly
`
`warned against confining the claims to those embodiments”); See Nikon Corp. v. ASM
`
`Lithography B.V., 308 F.Supp.2d 1039, 1088 (N.D. Cal. 2004) (“A ‘cardinal sin of claim
`
`construction,’ the Federal Circuit has observed, is to import limitations into claims where claim
`
`language permits a construction broader than the embodiments.”). By including “locate,”
`
`Defendants improperly combine the functions of the “probe message” and the “probe
`

`
`Further, Defendants’ proposed construction unnecessarily limits the origin of a message
`
`(e.g., “sent by the network operation center”). Where appropriate, the Claims already discloses
`
`from where the messages originate. See ’428 at [9:16-19, 26-28] (“a network operations center
`
`. . . comprising . . . means for transmitting a probe message to the mobile unit if, after

`
`
`
`
`
`’946 Patent, Claim 8
`
`
`
`These claims do not require construction as there is no material claim construction
`
`dispute. O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir.
`
`2008). MTel does not contend that retransmission occurs automatically without any user
`
`involvement. Furthermore, the terms plain and ordinary meanings are clear. “Only upon
`
`actuation of the switch” means “not until the switch is put into action.” This meaning is clear
`
`from the Claim, which would be easily understandable to the jury without construction. Further,
`
`extrinsic evidence supports this plain and ordinary meaning. See Exh. 2, Random House
`
`Dictionary (1987) (defining “actuate” as “to put into action; start a process; turn on: to actuate a
`
`machine.”).
`
`Defendants inject a requirement that “actuation” be “user actuation.” While it is clear
`
`that the user must “desire[] retransmission from the communications network” (’946 at [32:2-4]),
`
`the patent does not require the user directly actuate the switch. Rather, the user may direct the
`
`switch to actuate through a physical (e.g., keyboard, touchscreen, etc.) and/or software (e.g.,
`
`operating system) based interface. ’946 at [17:38-40] (“The request retransmission button 1622
`
`could also be configured in a variety of ways and could be located anywhere on the mobile
`
`unit.”). If the patentees wanted to restrict “actuation” to the user actuation, they could have done
`
`so in either clause of Claim 1.3 Defendants’ “as opposed to automatically” limitation is also
`
`unnecessary as the claim language makes clear that transmission occurs “only upon” the
`
`“actuation of the switch” or the “receipt of the indication.”
`
`
`3
`Indeed, after many negotiations between the applicant and the USPTO, the applicant proposed the third and
`final amendment to Claim 1. Applicant added “actuatable to specify a portion of the displayed message for
`which a user desires retransmission” and deleted “allowing a user to selectively request retransmission of a
`portion of said message.” Thus, Defendants propose including a limitation specifically withdrawn by the
`patentees during prosecution. Exh. 3 at 1-2.

`
`In the alternative:

`
`
`
`A PHOSITA would understand the plain and ordinary meaning of “canned” to be
`
`“predefined” and “message” to be “a sequence of characters used to convey information or data.”
`
`Exh. 1, Newton’s TeleCom Dictionary, 11th Ed., 373 (1996) (defining “message”). “Response”
`
`simply means “an answer to an inquiry.” Id . at 510 (1996) (defining “response”). A “canned
`
`message” is described in the Specification as “certain messages with an improved degree of
`
`message compression.” ’506 at [1:40-41].
`
`Defendants limit a “canned message” to a “textual word or phrase,” but the ’506 Patent
`
`does not prohibit a message from being expressed by characters or symbols. Also, by inserting
`
`the limitation “previously stored,” Defendants create confusion because the Specification
`
`contemplates the canned messages being “updated.” See, e.g., ’506 at [2:1-6] (“In accordance
`
`with a feature of the present invention, the . . . canned message files may be updated . . . in order
`
`to customize the canned messages according to the needs of a particular group or organization of
`
`subscribers.”). The purpose of claim construction is “to clarify, and when necessary to explain

`
`Finally, the storage of responses and canned messages is clear from the claim language itself.
`
`See, e.g., ’506 at [9:58-61] (“maintaining at a network operation center a first file of canned
`
`messages and message codes respectively assigned to the canned messages”); ’506 at [10:53-56]
