SECOND CLAIM 

(Infringement of the ’625 Patent; T-Mobile)

information and belief, Defendants have not taken any action to stop their infringement. 

60. The T-Mobile Defendants have, under 35 U.S.C. § 271(a), directly infringed, and continue to 

directly infringe, literally and/or under the doctrine of equivalents, one or more claims, 

3 See, e.g., https://www.oneplus.com/us/tmo-deals (last visited September 26, 2023). 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 11 of 27 PageID #: 11
including without limitation at least claim 16 of the ’625 Patent, by making, using, testing, 

selling, leasing, offering for sale, and/or importing hardware and software used in the cellular, 

Wi-Fi, and IP Multimedia System networks, and by offering access to those networks 

(excluding any products licensed under the ’625 Patent). An exemplary claim chart concerning 

one way in which T-Mobile infringes claim 16 of the ’625 Patent is attached as Exhibit 13.

part of a claimed invention, where the material part is not a staple article of commerce and is 

incapable of substantial noninfringing use. For example, T-Mobile provides, owns, operates, 

sells, offers to sell, leases, uses, and/or imports various hardware and software enabling access 

to the cellular, Wi-Fi, and IP Multimedia System networks (such as that shown in Exhibit 12) 

that are not staple articles of commerce and are incapable of substantial non-infringing uses. 

Accordingly, even if T-Mobile does not provide, own, operate, sell, offer to sell, lease, and/or

directly infringe, literally and/or under the doctrine of equivalents, one or more claims, 

including without limitation at least claim 1 of the ’063 Patent, by making, using, testing, 

selling, leasing, offering for sale, and/or importing networks and network switches that provide 

for the control of user high-speed data across the cellular network (excluding any products 

licensed under the ’063 Patent). An exemplary claim chart concerning one way in which TMobile infringes claim 1 of the ’063 Patent is attached as Exhibit 14. 

69. The T-Mobile Defendants have also indirectly infringed, and continue to indirectly infringe, 

the ’625 Patent under 35 U.S.C. § 271(b) and (c).

70. The T-Mobile Defendants knowingly, intentionally actively aid, abet, and induce others to 

directly infringe at least claim 1 of the ’063 Patent by, for example, offering access to (and 

encouraging use of) the wireless networks. For instance, T-Mobile advertises that data rates

data networks after reaching certain data volume usage. See Exhibit 14. Moreover, Valtrus 

put T-Mobile on notice of its infringement of the ’063 Patent no later than on or about August 

26, 2022. 

71. The T-Mobile Defendants contribute to the direct infringement of at least claim 1 of the ’063 

Patent under 35 U.S.C. § 271(c) by supplying, with knowledge of the ’063 Patent, a material 

part of a claimed invention, where the material part is not a staple article of commerce and is

article of commerce and are incapable of substantial noninfringing use. Accordingly, even if 

T-Mobile does not provide, own, operate, sell, offer to sell, lease, and/or import all of the 

hardware and software involved, it is still contributing to the infringement of others, including 

customers. 

72. The T-Mobile Defendants’ infringement has been willful in view of the above, and their failure 

to take any action, even after being put on notice, to stop their infringement or inducement of, 

or contribution to, infringement by others.

80. The T-Mobile Defendants have been on notice of the ’264 Patent and a specific factual basis 

for their infringement of the ’264 Patent since at least on or about January 5, 2022. On 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 15 of 27 PageID #: 15
information and belief, the T-Mobile Defendants did not take any action to stop their 

infringement. 

81. Defendants have, under 35 U.S.C. § 271(a), directly infringed, literally and/or under the 

doctrine of equivalents, one or more claims, including without limitation at least claim 1 of the 

’264 Patent, by using, testing, selling, leasing, offering for sale, and/or importing mobile 

devices with ARM-based processors supporting DynamIQ Shared Units (excluding any 

products licensed under the ’264 Patent). 

82. For example, the T-Mobile Defendants have sold, offered for sale, used and tested devices, 

including the Lenovo moto g stylus 5G (2022), that contain the Qualcomm Snapdragon Kryo. 

An exemplary claim chart concerning one way in which T-Mobile has infringed claim 1 of the 

’264 Patent is attached as Exhibit 16. 

83. The OnePlus Defendants and T-Mobile Defendants have sold, offered for sale, used and tested 

OnePlus devices, including the OnePlus 8 5G, that contain the Qualcomm Snapdragon 865. 

An exemplary claim chart concerning one way in which T-Mobile Defendants and OnePlus 

Defendants have infringed claim 1 of the ’264 Patent is attached as Exhibit 17. 

84. The T-Mobile Defendants also indirectly infringed the ’264 Patent under 35 U.S.C. § 271(b)

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 16 of 27 PageID #: 16
86. The T-Mobile Defendants contributed to the direct infringement of at least claim 1 of the ’264 

Patent under 35 U.S.C. § 271(c) by supplying, with knowledge of the ’264 Patent, a material 

part of a claimed invention, where the material part is not a staple article of commerce and is 

incapable of substantial noninfringing use. For example, the identified ARM-based processor 

supporting DynamIQ Shared Units (per the claim chart) is a material part of the claimed 

invention, is not a staple article of commerce, and is incapable of substantial non-infringing 

uses. Additionally, the T-Mobile Defendants sold mobile devices, including those noted above, 

that contain Qualcomm Snapdragon chips (and/or similar chips in the Snapdragon 8xx family), 

which, when used, form a material part of the claimed invention, where the material part is not 

a staple article of commerce and is incapable of substantial non-infringing use. 

87. The T-Mobile Defendants’ infringement has been willful in view of the above, and their failure 

to take any action, even after being put on notice, to stop their infringement or inducement of, 

or contribution to, infringement by others. 

SIXTH CLAIM 

(Infringement of the ’892 Patent; T-Mobile) 

88. Valtrus re-alleges and incorporates herein by reference paragraphs 1-87 of its Complaint.

for their infringement of the ’892 Patent since at least on or about June 13, 2023. On 

information and belief, the T-Mobile Defendants have not taken any action to stop their 

infringement. 

91. The T-Mobile Defendants have, under 35 U.S.C. § 271(a), directly infringed, and continue to 

directly infringe, literally and/or under the doctrine of equivalents, one or more claims, 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 17 of 27 PageID #: 17
including without limitation at least claim 10 of the ’892 Patent, by using, testing, selling, 

leasing, offering for sale, and/or importing mesh network systems comprising access points 

(excluding any products licensed under the ’892 Patent). For example, T-Mobile has sold, 

offered for sale, imported, used and tested mesh network compatible access points and 

extenders such as the Google Nest Wi-Fi mesh network system. An exemplary claim chart 

concerning one way in which T-Mobile infringes claim 10 of the ’892 Patent is attached as

92. The T-Mobile Defendants also indirectly infringed, and continue to indirectly infringe, the ’892 

Patent under 35 U.S.C. § 271(b) and (c). 

93. The T-Mobile Defendants are knowingly and intentionally actively aiding, abetting, and 

inducing others to directly infringe at least claim 10 of the ’892 Patent (such as customers in 

this District and throughout the United States) by, for example, selling, offering for sale, and 

encouraging customers to use and create infringing mesh network systems comprising access 

points.5

 Moreover, Valtrus put T-Mobile on notice of its infringement of the ’892 Patent no 

later than on or about September 25, 2023.

Patent under 35 U.S.C. § 271(c) by supplying, with knowledge of the ’892 Patent, a material 

part of a claimed invention, where the material part is not a staple article of commerce and is 

incapable of substantial noninfringing use. For example, the identified mesh Wi-Fi devices are 

a material part of the claimed invention, are not staple articles of commerce, and are incapable 

of substantial non-infringing uses. 

5 See, e.g., https://www.t-mobile.com/home-internet/what-is-mesh-wifi (last visited September 

26, 2023). 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 18 of 27 PageID #: 18
95. The T-Mobile Defendants’ infringement has been willful in view of the above, and their failure 

to take any action, even after being put on notice, to stop their infringement or inducement of, 

or contribution to, infringement by others. 

SEVENTH CLAIM

96. Valtrus re-alleges and incorporates herein by reference paragraphs 1-95 of its Complaint. 

97. The ’155 Patent is generally directed to systems and methods for the management and control 

of interactive media sessions. 

98. The T-Mobile Defendants have been on notice of the ’155 Patent and a specific factual basis 

for their infringement of the same since at least on or about September 25, 2023. On 

information and belief, the T-Mobile Defendants have not taken any action to stop their 

infringement. 

99. The T-Mobile Defendants have, under 35 U.S.C. 271(a), directly infringed, and continue to 

directly infringe, literally and/or under the doctrine of equivalents, one or more claims,

components operable to implement an IMS (excluding any products licensed under the ‘155 

Patent). An exemplary claim chart concerning one way in which T-Mobile infringes claim 1 

of the ’155 Patent is attached as Exhibit 19. 

100. The T-Mobile Defendants also indirectly infringed, and continue to indirectly infringe, the 

’155 Patent under 35 U.S.C. § 271(b) and (c). 

101. The T-Mobile Defendants knowingly and intentionally actively aided, abetted, and induced 

others to directly infringe at least claim 1 of the ’155 Patent (such as customers in this District 

and throughout the United States) by, for example, selling, offering for sale, and encouraging 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 19 of 27 PageID #: 19
customers to use hardware/software compatible with IMS. Moreover, Valtrus put the T-Mobile 

Defendants on notice of their infringement of the ’155 Patent no later than on or about 

September 25, 2023. 

102. The T-Mobile Defendants contributed to the direct infringement of at least claim 1 of the

EIGHTH CLAIM 

(Infringement of the ’539 Patent; T-Mobile and OnePlus) 

104. Valtrus re-alleges and incorporates herein by reference paragraphs 1-103 of its Complaint. 

105. The ’539 Patent is generally directed to computer architecture and techniques for 

controlling access to resources in a computer system. 

106. The OnePlus Defendants have been on notice of the ’539 Patent and a specific factual basis 

for their infringement of the ’539 Patent since at least on or about September 16, 2022. The TMobile Defendants have been on notice of the ’539 Patent and a specific factual basis for their 

infringement of the ’539 Patent since at least on or about September 25, 2023. On information 

and belief, Defendants have not taken any action to stop their infringement. 

107. Defendants have, under 35 U.S.C. § 271(a), directly infringed, and continue to directly 

infringe, literally and/or under the doctrine of equivalents, one or more claims, including 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 20 of 27 PageID #: 20
without limitation at least claim 1 of the ’539 Patent, by making, using, testing, selling, offering 

for sale, and/or importing devices featuring a processor based on an ARM A-Profile 

architecture, such as ARMv8-A (excluding any products licensed under the ’539 Patent). 

108. For example, OnePlus and T-Mobile have sold, offered for sale, used and tested OnePlus 

devices, including the OnePlus 9 5G, that contain the Qualcomm Snapdragon 865. An 

exemplary claim chart concerning one way in which T-Mobile and OnePlus have infringed 

claim 1 of the ’539 Patent is attached as Exhibit 20. 

109. Defendants also indirectly infringed, and continue to indirectly infringe, the ’539 Patent 

under 35 U.S.C. § 271(b) and (c). 

110. Defendants knowingly and intentionally actively aided, abetted, and induced others to 

directly infringe at least claim 1 of the ’539 Patent (such as customers in this District and 

throughout the United States) by, for example, selling, offering for sale, and encouraging 

customers to use mobile devices with infringing chips. Moreover, Valtrus put the OnePlus 

Defendants on notice of their infringement of the ’539 Patent no later than on or about 

September 16, 2022, and the T-Mobile Defendants on notice of their infringement of the ’539 

Patent no later than on or about September 25, 2023. 

111. Defendants contributed to the direct infringement of at least claim 1 of the ’539 Patent 

under 35 U.S.C. § 271(c) by supplying, with knowledge of the ’539 Patent, a material part of 

a claimed invention, where the material part is not a staple article of commerce and is incapable 

of substantial noninfringing use. For example, the identified ARM A-profile based processors 

(per the claim chart) are a material part of the claimed invention, are not a staple article of 

commerce, and are incapable of substantial non-infringing uses. Additionally, Defendants sold 

mobile devices, including those noted above, that contain ARM A-profile based processors, 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 21 of 27 PageID #: 21
which, when used, form a material part of the invention, where the material part is not a staple 

article of commerce and is incapable of substantial non-infringing use. 

112. Defendants’ infringement has been willful in view of the above, and their failure to take 

any action, even after being put on notice, to stop their infringement or inducement of, or 

contribution to, infringement by others. 

NINTH CLAIM 

(Infringement of the ’364 Patent; T-Mobile and OnePlus) 

113. Valtrus re-alleges and incorporates herein by reference paragraphs 1-112 of its Complaint. 

114. The ’364 Patent is generally directed to an advanced conference call system. 

115. The T-Mobile Defendants have been on notice of the ’364 Patent and a specific factual 

basis for their infringement of the ’364 Patent since at least on or about January 5, 2022. The 

OnePlus Defendants have been on notice of the ’364 Patent and a specific factual basis for 

their infringement of the ’364 Patent since at least on or about September 22, 2021. On 

information and belief, Defendants did not take any action to stop their infringement. 

116. T-Mobile has, under 35 U.S.C. § 271(a), directly infringed, literally and/or under the 

doctrine of equivalents, one or more claims, including without limitation at least claim 1 of the 

’364 Patent, by making, using, testing, selling, offering for sale, and/or importing their 

implementations of a conference call telephone system (excluding any products licensed under 

the ’364 Patent). 

117. Alternatively, and/or in addition, T-Mobile and OnePlus are jointly liable for infringement 

of the ’364 Patent because they acted in a joint enterprise. A joint enterprise existed because, 

as shown in Exhibit 21, there was (1) an agreement, express or implied, between T-Mobile and 

OnePlus (for example, Defendants advertised that they were engaged in a partnership); (2) a 

common purpose to be carried out by the group (for example, Defendants advertised that they 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 22 of 27 PageID #: 22
shared an ideology and sought to build a community in the United States); (3) a community 

or pecuniary interest in that purpose, among the members (for example, Defendants sold 

infringing mobile devices and plans together); and, on information and belief, (4) Defendants 

shared an equal right to a voice in the direction of the enterprise, which gave an equal right of 

control. 

118. For example, Defendants provided a conference call telephone system. An exemplary 

claim chart concerning one way in which Defendants have infringed claim 1 of the ’364 Patent 

is attached as Exhibit 20. 

119. Defendants also indirectly infringed the ’364 Patent under 35 U.S.C. § 271(b) and (c). 

120. Defendants knowingly and intentionally actively aided, abetted, and induced others to 

directly infringe at least claim 1 of the ’364 Patent (such as customers in this District and 

throughout the United States) by, for example, selling, offering for sale, and encouraging 

customers to use conference call telephone systems. Moreover, Valtrus put the T-Mobile 

Defendants on notice of their infringement of the ’364 Patent no later than on or about January 

5, 2022, and the OnePlus Defendants on notice of the ’364 Patent no later than on or about 

September 22, 2021. 

121. Defendants’ infringement has been willful in view of the above and their failure to take any 

action, even after being put on notice, to stop their infringement or inducement of infringement 

by others. 

THE ’050 PATENT 

(T-Mobile) 

122. Valtrus re-alleges and incorporates herein by reference paragraphs 1-121 of its Complaint. 

123. The ’050 patent is generally directed to systems and methods for interference mitigation in 

wireless communications. 

Case 2:23-cv-00444-JRG Document 1 Filed 09/27/23 Page 23 of 27 PageID #: 23
124. T-Mobile Defendants have been on notice of the ’050 patent and a specific factual basis for 

their likely infringement of the ’050 patent since at least on or about January 5, 2022. 

125. Valtrus believes that the T-Mobile Defendants have, under 35 U.S.C. § 271(a), directly 

infringed, and continue to directly infringe, literally and/or under the doctrine of equivalents, 

one or more claims, including without limitation at least claim 1 of the ’050 Patent, by making, 

using, testing, selling, leasing, offering for sale, and/or importing broadband gateway products, 

including, for example, Wi-Fi6 enabled products, which, when operated, perform the method 

of claim 1 of the ’050 patent (excluding any products licensed under the ’050 patent). An 

exemplary claim chart concerning T-Mobile’s likely infringement of claim 1 of the ’050 patent 

is attached as Exhibit 20. Valtrus further believes that the T-Mobile Defendants are indirectly 

infringing the ’050 patent under 35 U.S.C. § 271(b) and/or (c).

WHEREFORE, Valtrus prays for judgment against Defendants as follows: 

A. That the T-Mobile Defendants have infringed each of the Asserted Patents, and unless 

enjoined, will continue to infringe one or more of the Asserted Patents;

attorneys’ fees and costs in this action; and 

I. That Valtrus be awarded such other and further relief, including equitable relief, as this 

Court deems just and proper.
