`
`JURISDICTION AND VENUE
`
`10.
`
`This Court has subject matter jurisdiction over this action pursuant to 28 U.S.C.
`
`§§ 1331 and 1338(a) because it arises under the patent laws of the United States.
`
`11.
`
`This Court has personal jurisdiction over Defendants, which have committed acts
`
`of infringement in Texas and in this judicial district in violation of 35 U.S.C. § 271. For
`
`instance, Defendants have performed infringing methods, and made and used infringing systems
`
`that provide wireless telecommunications services. The Defendants have derived and continue
`
`to derive substantial revenue from the sale and use of infringing products and services in this
`
`district. In addition, AT&T Inc., AT&T Corp., AT&T Mobility LLC, AT&T Mobility II LLC,
`
`and AT&T Services, Inc. are registered to do business in Texas, and the Defendants own and/or
`
`maintain numerous stores and office locations within Texas. In view of the foregoing, this Court
`
`possesses both general and specific jurisdiction over the Defendants.
`
`12.
`
`AT&T maintains a significant physical presence in this judicial district. For
`
`example, there are numerous AT&T retail stores within this judicial district, including in Allen,
`
`Athens, Beaumont, Canton, Denton, Frisco, Kilgore, Lindale, Longview, Marshall,
`
`Nacogdoches, Sulphur Springs, Texarkana, and Tyler, Texas. AT&T uses these stores to sell
`
`telecommunications services that infringe the Patents-in-Suit (discussed below). These stores are
`
`physical places within the district, are regular and established places of business, and are
`
`AT&T’s places.
`
`13.
`
`AT&T further maintains a foundry within this judicial district in Plano, Texas,
`
`“encompassing all aspects of an industry environment – from manufacturing to distribution to
`
`3
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 4 of 32 PageID #: 4
`
`retail” and enabling AT&T’s customers “to test potential 5G solutions.”1 AT&T uses this
`
`foundry to design, test, use, and sell telecommunications services that infringe the Patents-in-
`
`Suit. This foundry is a physical place within the district, is a regular and established place of
`
`business, and is AT&T’s place.
`
`14.
`
`For at least these reasons, venue is proper in this judicial district. AT&T resides
`
`in this judicial district within the meaning of 28 U.S.C. § 1400(b). AT&T has committed
`
`infringement acts within this district and has regular and established places of business here.
`
`THE PATENTS-IN-SUIT
`
`U.S. Patent No. 7,333,822
`
`15.
`
`On February 19, 2008, the United States Patent and Trademark Office (“USPTO”
`
`or “PTO”) issued U.S. Patent No. 7,333,822, entitled “Method for Transmitting Messages in a
`
`Telecommunication Network.” A true and correct copy of U.S. Patent No. 7,333,822 is attached
`
`hereto as Exhibit A and incorporated herein by this reference.
`
`16.
`
`On July 16, 2008, a third party requester, HTC Corp. filed a request for Inter
`
`Partes Reexamination of U.S. Patent No. 7,333,822, and the PTO instituted reexamination
`
`pursuant to Inter Partes Reexamination Control No. 95/001,211. During this reexamination, the
`
`patent owner amended some of the claims, canceled other claims, and added new claims. The
`
`PTO Examiner subsequently determined that claims 1, 17, 22 and 27-48 are patentable over all
`
`of the prior art cited during the original examination and reexamination. The third-party
`
`requester then filed an appeal to the Patent Trial and Appeal Board (“PTAB”). On May 30,
`
`2013, the PTAB issued a Decision on Appeal affirming the Examiner’s determination that these

`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 5 of 32 PageID #: 5
`
`claims are patentable. On September 13, 2013, the PTO issued Inter Partes Reexamination
`
`Certificate Number 7,333,822 C1, which is now part of the ‘822 patent.
`
`17.
`
`IPCom is the assignee and owner of all right, title, and interest in and to the ’822
`
`Patent, including the right to assert all causes of action arising under said patent and the right to
`
`any and all remedies for infringement, including past damages.
`
`18.
`
`The invention of the ’822 Patent pertains to methods for transmitting messages in
`
`a mobile telecommunications network that can utilize two kinds of message services, such as: a
`
`short message service (“SMS”) and a multimedia messaging service (“MMS”). See ’822 Patent,
`
`4:23-29. Such networks may comprise telecommunications equipment including Multimedia
`
`Messaging Service Centers (“MMSCs”), Short Message Service Centers (“SMSCs”), wireless
`
`base stations, and mobile phones. Id., 2:27-30, 2:66-3:31. The invention of the ’822 Patent is
`
`designed, inter alia, to solve certain technical problems affecting message transmission. Id. For
`
`example, in order to transmit messages, telecommunications equipment needs to set up a
`
`“connection” (or “session”). Id., 4:25-29. However, setting up these connections requires
`
`certain “overhead” defined by the use of network resources, including “bandwidth” and
`
`“signaling” resources. Id., 4:25-29, 4:64-5:6. Among other things, the invention of the ’822
`
`Patent reduces the amount of overhead needed to transmit messages within the network. Id.
`
`This improves efficiency and capacity.
`
`19.
`
`The ’822 Patent claims are directed to patent-eligible, non-abstract ideas in that
`
`they provide technical solutions to at least the technical problems described above. The claims
`
`relate to the sending of a dedicated MMS message using a short message of the SMS service,
`
`wherein the short message may include: a header portion, a data portion having an identification
`
`of a type of the dedicated MMS message, and also an identifier for indicating a presence of the
`
`5
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 6 of 32 PageID #: 6
`
`dedicated MMS message in the data portion of the short message. Id., 5:50-8:34. In one
`
`embodiment, the short message carries a dedicated MMS notification message, which may
`
`indicate the presence of another type of MMS message on an MMS server in the
`
`telecommunications network. Id., 6:55-7:60. By using the short message to send the dedicated
`
`MMS notification message, the telecommunications network is able to dispense with the
`
`“overhead” associated with “setting up a connection/session.” Id., 4:25-29, 4:67-5:6. The ’822
`
`Patent further explains that by employing the claimed methods, no “additional signaling for
`
`transmitting notifications” is required, and therefore network bandwidth and signaling resources
`
`are conserved. Id., 4:67-5:6. Thus, the claimed inventions are directed to patent-eligible, non-
`
`abstract ideas because they improve the overall functioning of a telecommunications system.
`
`Further, the methods claimed in the ’822 Patent cannot be performed as mental steps by a
`
`human, nor do they represent the application of a generic computer to any well-known method of
`
`organizing human behavior.
`
`U.S. Patent No. 10,382,909
`
`20.
`
`On August 13, 2019, the PTO issued United States Patent No. 10,382,909,
`
`entitled “Method for Transmitting Messages in a Telecommunications Network.” A true and
`
`correct copy of the ’909 Patent is attached hereto as Exhibit B and incorporated herein by this
`
`reference.
`
`21.
`
`The ’909 Patent is a Division of application No. 11/975,428, which is a
`
`continuation of the ’822 Patent. See ’909 Patent, cover page. The ’909 Patent and the ’822
`
`Patent share the same figures and written description. During examination of the ’909 Patent,
`
`the Examiner reviewed the art cited during prosecution of the ’822 Patent, the art cited in the
`
`Inter Partes Reexamination of the ’822 Patent, Control No. 95/001,211, and the PTAB’s
`
`6
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 7 of 32 PageID #: 7
`
`Decision on Appeal in the reexamination of the ’822 Patent. The Examiner subsequently
`
`determined the claims of the ’909 Patent to be patentable.
`
`22.
`
`IPCom is the assignee and owner of all right, title, and interest in and to the ’909
`
`Patent, including the right to assert all causes of action arising under said patent and the right to
`
`any and all remedies for infringement, including past damages.
`
`23.
`
`The ’909 Patent describes, inter alia, methods and apparatus for use in
`
`transmitting messages in a mobile telecommunications network that provides SMS and MMS
`
`services using MMSCs, SMSCs, wireless base stations, and mobile phones. See ’909 Patent,
`
`3:3-34, 7:39-52, 8:12-9:26. The invention of the ’909 Patent solves technical problems involving
`
`the transmission of messages. Id. In order to transmit the messages, the telecommunications
`
`equipment needs to set up a “connection” (or “session”), but setting up these connections
`
`requires certain “overhead” defined by use of network resources, including “bandwidth”
`
`resources. Id., 4:11-63. The invention of the ’909 Patent reduces the amount of overhead
`
`needed to send messages. Id. This improves the efficiency and capacity of the network.
`
`24.
`
`The ’909 Patent claims are directed to patent-eligible, non-abstract ideas because
`
`they provide technical solutions to the technical problems described above. The claims relate to
`
`sending a dedicated MMS message using a short message of the SMS service. Id., 4:11-5:13. In
`
`one embodiment, the short message carries a dedicated MMS notification message, which may
`
`indicate the presence of another type of MMS message on an MMS server in the
`
`telecommunications network. See id.; see also id., 6:30-7:29. By using the short message to
`
`send the dedicated MMS notification message, the telecommunications network is able to
`
`dispense with the “overhead” associated with “setting up a connection/session.” Id., 4:11-63.
`
`The ’909 Patent further explains that by employing the claimed methods, no “additional
`
`7
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 8 of 32 PageID #: 8
`
`signaling for transmitting notifications” is required, and therefore the network bandwidth and
`
`signaling resources are conserved. Id. Thus, the claimed inventions are also directed to patent-
`
`eligible, non-abstract ideas because they improve the overall functioning of a
`
`telecommunications system. Further, the methods claimed in the ’909 Patent cannot be
`
`performed as mental steps by a human, nor do they represent the application of a generic
`
`computer to any well-known method of organizing human behavior.
`
`U.S. Patent No. 6,813,261
`
`25.
`
`On November 2, 2004, the PTO issued United States Patent Number 6,813,261,
`
`entitled “Method of Mobile Communication and Apparatus Therefor.” IPCom is the assignee
`
`and owner of all right, title, and interest in and to the ’261 Patent, including the right to assert all
`
`causes of action arising under said patent and the right to any and all remedies for infringement,
`
`including past damages. A true and correct copy of the ’261 Patent is attached hereto as Exhibit
`
`C and incorporated herein by this reference.
`
`26.
`
`In general, the ’261 Patent describes methods and apparatuses for initiating and
`
`establishing “efficient communication of data between a base station and a plurality of mobile
`
`terminals” in a cellular network. See, e.g., ’261 Patent at Abstract. The invention includes, for
`
`example, a base station that “receiv[es] an alert signal from a mobile terminal,” “evaluat[es] the
`
`alert signal for the presence of a particular code by comparing the alert signal with a plurality of
`
`codes,” and “if the particular code is present, transmit[s] an alert response to the mobile terminal,
`
`the alert response containing data corresponding to the particular code.” Id. at 19:9-20:3.
`
`27.
`
`The ’261 Patent claims relate to technical solutions to technical problems that
`
`arise in the design and implementation of traditional cellular networks. More particularly, the
`
`patent identifies several technical drawbacks of prior art systems, including, for example:
`
`8
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 9 of 32 PageID #: 9
`
`
`
`
`
`“In the above-mentioned conventional mobile communication system…a plurality
`of reservation packets collide in the base station when the reservation packets are
`transmitted from a plurality of mobile terminals to the base station, and the contents
`of the reservation packets cannot be correctly read out in the base station. Therefore,
`the mobile terminals must transmit reservation packets again. In order to transmit
`the reservation package again as described above, waiting times are set in random
`fashion so that the reservation packages will not collide again. When the reservation
`packets collide, the transmission efficiency of data greatly decreases.” Id., 1:58-
`2:2.
`
`“Furthermore, in the above-mentioned conventional mobile communications
`system…data for making a reservation are transmitted and received in addition to
`the data that are to be transmitted. Therefore, a ratio for the data that are desired to
`be transmitted decreases in the whole data that are transmitted and received
`between the base station and the mobile terminals. When the consecutive data are
`to be transmitted being divided into a plurality of data packages…, in particular, a
`reservation packet is transmitted for the transmission of each data packet, and the
`packets occupy a large ratio in the whole data transmitted and received between the
`base station and the mobile terminal.” Id., 2:3-16. As a result, “the ratio for the
`data that are desired to be transmitted becomes low with respect to the entire
`amount of data” and “the communication capacity of data decreases by an amount
`corresponding to the electric power of transmitting the reservation packets.” Id., 2:
`48-50, 2:62-67.
`
`28.
`
`The ’261 Patent claims are directed to a patent-eligible, non-abstract idea as they
`
`relate to technical solutions to overcome at least the above described problems. For example, the
`
`patent identifies numerous advantages that the claimed techniques provide compared to
`
`traditional cellular networks. See, e.g., ’261 Patent, 3:1-7:15 (describing “representative
`
`examples of methods and apparatuses” which provide technology capable of (1) “efficiently
`
`transmitting and receiving data between the base station and a plurality of mobile terminals”; (2)
`
`“detecting the individual alert signals even when a plurality of alert signals are transmitted from
`
`a plurality of mobile terminals to the base station”; and (3) “maintaining, at a low level, the value
`
`of the alert signals transmitted from the mobile terminals”). The claimed techniques enhance the
`
`process for initiating and establishing data transfer between multiple mobile terminals and a base
`
`station, and therefore, improve the function of a computer and computer communication systems
`

`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 10 of 32 PageID #: 10
`
`within cellular networks. The methods claimed in the ’261 Patent cannot be performed as mental
`
`steps by a human, nor do they represent the application of a generic computer to any well-known
`
`method of organizing human behavior.
`
`29.
`
`The ’261 Patent claims inventive concepts that are significantly more than any
`
`patent-ineligible, abstract idea. In particular, the claimed technology, including individual
`
`limitations as well as ordered combinations of limitations, were not well-understood, routine, or
`
`conventional, and cover multiple advantages, and combinations of advantages, that were not
`
`well-understood, routine, or conventional. See, e.g., id. at 1:30-7:10.
`
`U.S. Patent No. 7,006,463
`
`30.
`
`On February 28, 2006, the PTO issued United States Patent Number 7,006,463,
`
`entitled, “CDMA Communication System and Its Transmission Power Control Method.” IPCom
`
`is the assignee and owner of all right, title, and interest in and to the ’463 Patent, including the
`
`right to assert any and all causes of action arising under said patent and the right to any remedies
`
`for infringement, including past damages. A true and correct copy of the ’463 Patent is attached
`
`hereto as Exhibit D and incorporated herein by this reference.
`
`31.
`
`In general, the ’463 Patent pertains to methods and apparatuses for providing
`
`“uplink channel transmission power control” in a CDMA telecommunications network. See,
`
`e.g., ’463 Patent at Abstract. Since “mobile terminals share the same frequency band to
`
`communicate with a single base station” uplink power control is important to limit unwanted
`
`interference in the communication channel. Id. at 1:19-31. The invention of the ’463 Patent
`
`provides for improved uplink power control involving, for example, transmitting power control
`
`signals to multiple “mobile terminals by using [a] common channel shared by the mobile
`
`terminals.” See, e.g., ’463 Patent at Abstract.
`
`10
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 11 of 32 PageID #: 11
`
`32.
`
`The invention of the ’463 Patent provides technical solutions to technical
`
`problems in conventional power control methods. Traditional transmission power control
`
`methods (e.g., for voice-only) operate under the assumption that there exists a pair of uplink and
`
`downlink traffic channels. Id. at 2:40-47. As the patent explains: “[i]f a paired downlink
`
`channel is provided only for the transmission power control of the uplink traffic channel, one
`
`downlink traffic channel is occupied by the transmission power control of only the uplink traffic
`
`channel. The use efficiency of traffic channels is lowered.” Id. at 2:48-52.
`
`33.
`
`The ’463 Patent claims are directed to a patent-eligible, non-abstract idea. To
`
`solve the above described technical problem in the prior art, the patent describes “a single
`
`downlink traffic channel common for all mobile stations,” which allows a base station to control
`
`the transmission power of a plurality of mobile stations without consuming capacity on
`
`individual downlink traffic channels, thereby increasing network efficiency. Id. at 2:53-57; see
`
`also id. at 10:10-25, 10:59-11:10. The ’463 Patent’s claimed techniques improve the
`
`performance and function of communication systems and cannot be performed as mental steps
`
`by a human, nor do they represent the application of a generic computer to any well-known
`
`method of organizing human behavior.
`
`34.
`
`The ’463 Patent claims inventive concepts that are significantly more than any
`
`patent-ineligible, abstract idea. In particular, the claimed technology, including individual
`
`limitations as well as ordered combinations of limitations, were not well-understood, routine, or
`
`conventional, and cover multiple advantages, and combinations of advantages, that were not
`
`well-understood, routine, or conventional. See, e.g., id. at 2:40-57.

`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 12 of 32 PageID #: 12
`
`35.
`
`On January 3, 2006, the PTO issued United States Patent Number 6,983,147,
`
`entitled “Method of transmitting signaling information, a master station, a mobile station and
`
`message elements.” IPCom is the assignee and owner of all right, title, and interest in and to the
`
`’147 Patent, including the right to assert all causes of action arising under said patent and the
`
`right to any and all remedies for infringement, including past damages. A true and correct copy
`
`of the ’147 Patent is attached hereto as Exhibit E and incorporated herein by this reference
`
`36.
`
`In general, the ’147 Patent describes methods and apparatuses for “transmitting
`
`signaling information between a master station and a slave station.” See ’147 Patent at Abstract.
`
`For example, “a message, which contains information regarding whether data to be sent is
`
`processed in the master station to increase the reception quality of this data at the slave station, is
`
`transmitted with the signaling information from the master station to the slave station” in a
`
`cellular network. See id. The invention may include, for example, a “transmitting station” that
`
`“transmit[s] information” “regarding whether data to be sent is processed by an additional
`
`transmitting station,” which is “successively assigned to the receiving station to increase a
`
`reception quality at the receiving station in accordance with measures relating to a transmission
`
`channel between the receiving station and as least one of the transmitting station and the
`
`additional transmitting station.” Id., 22:65-23:6.
`
`37.
`
`The ’147 Patent claims technical solutions to technical problems in the design and
`
`implementation of cellular networks, such as when initiating data transfers between multiple
`
`transmitters and a single mobile receiver. The ’147 Patent specification identifies technical
`
`drawbacks of traditional cellular networks, including at least, for example “that it is not known in
`
`the mobile station whether or not the base station is transmitting the data predistorted over the at
`
`least one specially allocated transmission channel. Therefore, the mobile station cannot decide
`
`12
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 13 of 32 PageID #: 13
`
`whether or not it must eliminate distortion from the data received by the base station over the
`
`specially set-up transmission channel.” Id., 1:31-37.
`
`38.
`
`The ’147 Patent claims are directed to a patent-eligible, non-abstract idea. They
`
`cover technical solutions to improve computer and electronic communications between cellular
`
`transmitters and receivers. For example, the patent identifies numerous specific advantages that
`
`the claimed techniques provide compared to traditional cellular networks. See, e.g., id. at 1:41-
`
`64 (describing “example method[s] according to the present invention” which provide
`
`technology capable of at least (1) “[S]etting up a transmission channel from the master station to
`
`the slave station, the slave station is able to decide how it may detect the data to be sent by the
`
`master station or the data to be sent by the other master station downstream from and assigned to
`
`the slave station in order to be able to guarantee optimum data reception”; (2) “If the slave
`
`station determines that the data to be sent by the corresponding master station has already been
`
`processed in the corresponding master station, then it may omit a complicated distortion
`
`elimination because the data will arrive at the slave station with a suitably increased reception
`
`quality”; and (3) “Power consumption at the slave station may be minimized in this manner,
`
`which may be advantageous when configuring the slave station as a mobile station with battery
`
`operation”). Further, the claimed technologies cannot be performed as mental steps by a human,
`
`nor do they represent the application of a generic computer to any well-known method of
`
`organizing human behavior.

`
`The ’147 Patent claims inventive concepts that are significantly more than any
`
`patent-ineligible, abstract idea. In particular, the claimed technology, including individual
`
`limitations as well as ordered combinations of limitations, were not well-understood, routine, or

`
`well-understood, routine, or conventional. See, e.g., id. at 22:62-23:16.
`
`U.S. Patent No. 7,778,310
`
`40.
`
`On August 17, 2010, the PTO issued United States Patent Number 7,778,310,
`
`entitled “Code division Multiple Access Mobile Communication System.” IPCom is the
`
`assignee and owner of all right, title, and interest in and to the ’310 Patent, including the right to
`
`assert all causes of action arising under said patent and the right to any remedies for infringement
`
`of it, including past damages. A true and correct copy of U.S. Patent No. 7,778,310 is attached
`
`hereto as Exhibit F and incorporated herein by this reference.
`
`41.
`
`In general, the ’310 Patent describes methods where “[i]n a mobile
`
`communication system using a code division multiple access (CDMA) method, spreading code
`
`detection and frame/slot timing synchronization (cell search) is conducted by using a long code
`
`masked symbol.” See ’310 Patent at Abstract; see also, e.g., 2:63-67 (“In order to conduct the
`
`cell search at high speed while suppressing the gate size and the power consumption, the
`
`spreading factor of the long code masked symbol is made smaller than spreading factors of other
`
`portions of the perch channels.”). For example, “[t]he spreading factor of the long code masked
`
`symbol is set to a value lower than spreading factors of other ordinary symbols,” in a cellular
`
`network. See id. The invention includes, for example, “transmitting, from a base station, control
`
`signals via first and second perch channels” where “perch channels being formed such that a
`
`long period code assigned to said base station and a first short period code are mapped in a first
`
`section of one slot of said first perch channel,” and also “transmitting, from said base station, a
`
`predetermined short period code mapped in a second section of said one slot of said second perch
`
`channel” where “said predetermined short period code for use by a mobile terminal for
`
`14
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 15 of 32 PageID #: 15
`
`performing cell search by calculating a correlation value for said second section of said one slot,”
`
`and “wherein said predetermined short period code is transmitted plural times within said second
`
`section of said one slot,” and finally “wherein said second section of said one slot of the first
`
`perch channel further includes a common short code, and spreading factors of said common short
`
`code and of said predetermined short period code are smaller than a spreading factor of said first
`
`short period code.” Id., 6:26-46.
`

`
`The ’310 Patent describes and claims technical solutions to technical problems in
`
`the design and implementation of wireless networks, and in particular, when performing
`
`synchronization and/or slot timing between a transmitter and mobile receiver. The ’310 Patent
`
`specification identifies technical drawbacks of traditional cellular networks, including at least,
`
`for example “[i]n the conventional system which conducts spreading process in the long code
`
`masked symbol section at the same symbol rate as in the data symbol section, it took the longest
`
`time in a first stage (slot timing synchronization) of the cell search” and “[i]f the MF with 64 taps
`
`is used, coefficient mode switchover becomes necessary in order to derive correlation values at
`
`all timing instants. This results in a problem that the time required for timing synchronization, in
`
`turn the time required for cell search becomes longer. On the other hand, if a MF with 256 taps
`
`is used, then the received signal can be despread with coefficients corresponding to one symbol
`
`set in the MF intact. Since the coefficient mode switchover thus becomes unnecessary,
`
`correlation at all timing instants can be derived at high speed. However, both the gate size and
`
`power consumption of the MF become very large.” Id. at 2:25-30 and 2:49-59.
`
`43.
`
`The ’310 Patent claims are directed to a patent-eligible, non-abstract idea. They
`
`provide specific technical solutions in order to improve computer and electronic communications
`
`between cellular transmitters and receivers. For example, the patent identifies numerous specific
`
`15
`
`
`
`Case 2:20-cv-00322-JRG Document 1 Filed 10/01/20 Page 16 of 32 PageID #: 16
`
`advantages that IPCom’s claimed techniques provide compared to traditional cellular
`
`networks. See, e.g., id. at Abstract (describing a benefit of the invention that “it becomes
`
`possible to reduce the circuit scale and power dissipation of the mobile terminal and raise the
`
`speed of cell search”) and 3:10-11 (“without increasing the gate size and power consumption,
`
`fast cell search thus becomes possible”). Further, the claimed technologies cannot be performed
`
`as mental steps by a human, nor do they represent the application of a generic computer to any
`
`well-known method of organizing human behavior.
`
`44.
`
`The ’310 Patent claims inventive concepts that are significantly more than any
`
`patent-ineligible, abstract idea. In particular, the claimed technology, including individual
`
`limitations as well as ordered combinations of limitations, were not well-understood, routine, or
`
`conventional, and cover multiple advantages, and combinations of advantages, that were not
`
`well-understood, routine, or conventional. See, e.g., id. at 6:26-53.
