(LEAD CASE)

PROTECTIVE ORDER

WHEREAS, Plaintiff XR Communications, LLC, dba Vivato Technologies (“Vivato”) 

and Defendants AT&T Services Inc., AT&T Mobility LLC, AT&T Corp., T- Mobile USA, Inc., 

Verizon Communications Inc. and Cellco Partnership d/b/a Verizon Wireless’s (collectively, 

“Defendants”), hereafter referred to as “the Parties,” believe that certain information that is or will 

be encompassed by discovery demands by the Parties involves the production or disclosure of 

trade secrets, confidential business information, or other proprietary information;

WHEREAS, the Parties seek a protective order limiting disclosure thereof in accordancewith 

Federal Rule of Civil Procedure 26(c):

THEREFORE, it is hereby stipulated among the Parties and ORDERED that:

1. Each Party may designate as confidential for protection under this Order, in whole or in part, 

any document, information or material that constitutes or includes, in whole or in part, 

confidential or proprietary information or trade secrets of the Party or a Third Party to whom 

the Party reasonably believes it owes an obligation of confidentiality with respect to such 

document, information or material (“Protected Material”). Protected Material shall be

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 1 of 24 PageID #: 1020
2

designated by the Party producing it by affixing a legend or stamp on such document, 

information or material as follows: “CONFIDENTIAL,” “RESTRICTED –

ATTORNEYS’ EYES ONLY,” or “RESTRICTED CONFIDENTIAL SOURCE CODE”

(the “Designation”). The Designation shall be placed clearly on each page of the Protected 

Material (except deposition and hearing transcripts) for which such protection issought. For 

deposition and hearing transcripts, the Designation shall be placed on the cover page of the 

transcript (if not already present on the cover page of the transcript when received from the 

court reporter) by each attorney receiving a copy of the transcript after that attorney 

receives notice of the designation of some or all of that transcript as “CONFIDENTIAL,” 

“RESTRICTED – ATTORNEYS’ EYES ONLY,” or “RESTRICTED CONFIDENTIAL 

SOURCE CODE.”

2. Any document produced under Patent Rules 2-2, 3-2, and/or 3-4 before issuance of this 

Order with the designation “Confidential” or “Confidential - Outside Attorneys’ Eyes Only” 

shall receive the same treatment as if designated “RESTRICTED - ATTORNEYS’ EYES 

ONLY” under this Order, unless and untilsuch document isredesignated to have a different 

classification under this Order.

3. With respect to documents, information or material designated “CONFIDENTIAL, 

“RESTRICTED - ATTORNEYS’ EYES ONLY,” or “RESTRICTED CONFIDENTIAL 

SOURCE CODE” (“DESIGNATED MATERIAL”),1 subject to the provisions herein and 

unless otherwise stated, this Order governs, without limitation: (a) all documents, 

electronically stored information, and/or things as defined by the Federal Rules of Civil 

Procedure; (b) all pretrial, hearing or deposition testimony, or documents marked as exhibits

1 The term DESIGNATED MATERIAL is used throughout this Protective Order to refer to the class 

of materials designated as “CONFIDENTIAL,” “RESTRICTED - ATTORNEYS’ EYES ONLY,” 

or “RESTRICTED CONFIDENTIAL SOURCE CODE,” both individually and collectively.

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 2 of 24 PageID #: 1021

or for identification in depositions and hearings; (c) pretrial pleadings, exhibits to pleadings 

and other court filings; (d) affidavits; and (e) stipulations. All copies, reproductions, 

extracts, digests and complete or partial summaries prepared from any DESIGNATED 

MATERIALS shall also be considered DESIGNATED MATERIAL and treated as such 

under this Order.

4. This Order does not confer any right to any one Defendant or future intervenors to access 

the DESIGNATED MATERIAL of any other Defendant or future intervenors.

5. A designation of Protected Material (i.e., “CONFIDENTIAL,” “RESTRICTED -

ATTORNEYS’ EYES ONLY,” or “RESTRICTED CONFIDENTIAL SOURCE CODE”) 

may be made at any time. Inadvertent or unintentional production of documents, 

information or material that has not been designated as DESIGNATED MATERIAL shall 

not be deemed a waiver in whole or in part of a claim for confidential treatment. Any party 

that inadvertently or unintentionally produces Protected Material without designating it as 

DESIGNATED MATERIAL may request destruction of that Protected Material by notifying 

the recipient(s), as soon as reasonably possible after the producing Party becomes aware of 

the inadvertent or unintentional disclosure, and providing replacement Protected Material 

that is properly designated. The recipient(s)shall then destroy all copies of the inadvertently 

or unintentionally produced Protected Materials and any documents, information or material 

derived from or based thereon.

6. “CONFIDENTIAL” documents, information and material may be disclosed only to the 

following persons, except upon receipt of the prior written consent of the designating party,

upon order of the Court, or as set forth in Paragraph 15 herein:

(a) outside counsel of record in this Action for the Parties;

(b) employees of such counsel assigned to and reasonably necessary to assist such 

counsel in the litigation of this Action;

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 3 of 24 PageID #: 1022
4

(c) in-house counsel for the Parties who either have responsibility for making decisions 

dealing directly with the litigation of this Action, or who are assisting outside 

counsel in the litigation of this Action, except that in-house counsel for a Defendant 

or any future intervenors shall not have access to the information or materials of 

any other Defendant or intervenor;

(d) outside consultants or experts (i.e., not existing employees or affiliates of a Party or 

an affiliate of a Party) retained for the purpose of this litigation, provided that: (1) 

such consultants or experts are not presently employed by the Parties hereto for 

purposes other than this Action; and (2) the Receiving Party and outside expert or 

consultant has complied with Paragraph 7 of thisOrder;

(e) independent litigation support services, including persons working for or as court 

reporters, graphics or design services, independent legal translating services, jury 

or trial consulting services, and photocopy, document imaging, and database 

services retained by counsel and reasonably necessary to assist counsel with the 

litigation of this Action; and

(f) any mediator who is assigned to hear this matter, and his or her staff, subject to 

their agreement to maintain confidentiality to the same degree as required by this 

Protective Order;

(g) the Court and its personnel.

7. Procedure for Disclosing Protected Material to Experts and Consultants. Prior to 

disclosure of Protected Material to any outside consultant or expert including their 

administrative and clerical staff whose duties and responsibilities require access to such 

materials to be authorized under Paragraph 6(d) of this order, the consultant or expert must 

execute the Undertaking attached as Appendix A to this Order and the Receiving Party 

must serve on the Producing Party a copy of the Undertaking, a current copy of the expert 

consultant’s CV, a list of the expert or consultant’s testifying and consulting work2 for the 

preceding 5 years (to the extent not included in the CV) (“Notice”). The Producing Party 

may object in writing to the disclosure within ten (10) days. At the expiration of the ten 

days, if no written objection is made, then the outside consultant or expert and their staff 

may access Protected Material. The Parties agree to promptly confer and use good faithto

2 To the extent the consulting work was a confidential engagement, the expert may anonymize this 

disclosure while still providing enough detail for the Producing Party to evaluate a direct conflict.

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 4 of 24 PageID #: 1023
5

resolve any such objection. If the Parties are unable to resolve any objection, the objecting 

Party may file a motion with the Court within seven (7) days of the Notice, or within such 

other time as the Parties may agree, seeking a protective order with respect to the proposed 

disclosure. The objecting Party shall have the burden of proving the need for a protective 

order. No disclosure shall occur until all such objections are resolved by agreement or 

Court order. This disclosure and objection procedure applies to each Producing Party 

separately. No disclosure of Protected Material may be provided to an expert or consultant 

that is involved in competitive decision-making, as defined by U.S. Steel v. United States, 

730 F.2d 1465, 1468 n.3 (Fed. Cir. 1984), on behalf of a Party or a competitor of a Party. 

Without the express prior written consent of the Defendant or future intervenor that 

produced the Protected Material, no expert or consultant retained by a Defendant or 

intervenor in this matter shall have access to Protected Material produced by another 

Defendant or future intervenor.

8. A Party shall designate documents, information or material as “CONFIDENTIAL” only 

upon a good faith belief that the documents, information or material contains confidential, 

commercially sensitive, or proprietary information or trade secrets of the Party or a Third 

Party to whom the Party reasonably believes it owes an obligation of confidentiality with 

respect to such documents, information or material.

9. Documents, information or material produced pursuant to any discovery request in this 

Action, including but not limited to Protected Material designated as DESIGNATED 

MATERIAL, shall be used by the Parties only in the litigation of this Action and shall not 

be used for any other purpose. Any person or entity who obtains access to DESIGNATED 

MATERIAL or the contents thereof pursuant to this Order shall not make any copies, 

duplicates, extracts, summaries or descriptions ofsuch DESIGNATED MATERIAL or any 

portion thereof except as may be reasonably necessary in the litigation of this Action. Any

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 5 of 24 PageID #: 1024
6

such copies, duplicates, extracts, summaries or descriptions shall be classified 

DESIGNATED MATERIALS and subject to all of the terms and conditions of this Order.

10. To the extent a Producing Party believes that certain Protected Material qualifying to be 

designated CONFIDENTIAL is so sensitive that its dissemination deserves even further 

limitation, the Producing Party may designate such Protected Material “RESTRICTED --

ATTORNEYS’ EYES ONLY,” or to the extent such Protected Material includes computer 

source code and/or live data (that is, data as it exists residing in a database or databases) 

(“Source Code Material”), or substantively relates to a Party’s Source Code Material, 

which for clarity shall include but is not limited to documents containing confidential, 

proprietary and/or trade secret source code, including computer code, scripts, assembly, 

object code, source code listings and descriptions of source code, object listings and 

descriptions of object code, Hardware Description Language (HDL), Register Transfer 

Level (RTL) files that describe the hardware design of any ASIC or other chip, and/or live 

data (that is, data as it exists residing in a database or databases that is specifically related 

to source code and not financial or other date), the Producing Party may designate such 

Protected Material as “RESTRICTED CONFIDENTIAL SOURCE CODE.”

11. For Protected Material designated RESTRICTED -- ATTORNEYS’ EYES ONLY, access 

to, and disclosure of, such Protected Material shall be limited to individuals listed in 

Paragraphs 6(a-b) and (d-h), provided however, that those individuals listed in Paragraph 

6(d) have complied with Paragraph 7 of this Order.

12. For Protected Material designated RESTRICTED CONFIDENTIAL SOURCE CODE, 

the following additional restrictions apply:

(a) Accessto a Party’s Source Code Materialshall be provided only on a “stand-alone” 

computer (that is, the computer may not be linked to any network, including a local 

area network (“LAN”), an intranet or the Internet) that is password protected, 

maintained in a secure, locked area, and disabled from having external storage 

devices attached to it (“Source Code Computer”).

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 6 of 24 PageID #: 1025

(b) Use or possession of any input/ output device or other electronic device (e.g., USB 

memory stick, cameras or any camera-enabled device, CDs, floppy disk, portable 

hard drive, laptop, cellular telephones, PDA, smartphones, voice recorders, 

peripheral equipment, DVDs, or drives of any kind, etc.) is prohibited while in the 

secured, locked area containing the Source Code Computer(s). Except as provided 

in Paragraph 12(g), the Receiving Party will not copy, remove, or otherwise transfer 

any portion of the Source Code Material from the Source Code Computer including, 

without limitation, copying, removing, or transferring any portion of the Source 

Code Material onto any other computers or peripheral equipment. The Receiving 

Party will not transmit any portion of the Source Code Material in any way from 

the location of the Source Code inspection. All persons entering the locked room 

containing the Source Code Computer(s) must agree to submit to reasonable 

security measures to insure they are not carrying any prohibited items before they 

will be given access to the locked room.

(c) The Source Code Computer(s) will be made available for inspection at the offices 

of outside counsel or any other mutually agreed-upon location, until the close of 

expert discovery, during normal business hours, which for purposes of this 

paragraph shall be 9:00 a.m. through 6:00 p.m. local time, on business days (i.e. 

weekdays that are not Federal or local holidays). However, upon reasonable notice 

from the Receiving Party, the Producing Party shall make reasonable efforts to 

accommodate the Receiving Party’s request for access to the Source Code 

Computer(s) outside of normal business hours. The Parties agree to cooperate in 

good faith such that maintaining the Producing Party’s Source Code Material at the 

offices of its outside counsel shall not unreasonably hinder the Receiving Party’s 

ability to efficiently and effectively conduct the prosecution or defense of this 

Action. No Defendant shall be required to make Source Code available for 

inspection prior to the date set forth in the Court’s scheduling order for producing 

documents;

(d) Prior to the first inspection of any requested Source Code Material, the Receiving 

Party shall provide at least ten (10) business days’ notice of the Source Code 

Material that it wishes to inspect, but the Receiving Party will work in good faith 

to provide earlier notice. Thereafter, the Receiving Party shall provide reasonable 

written notice to the Producing Party, which shall not be lessthan three (3) business 

days. In the event a Receiving Party intends to continue its review to the next 

business day, beyond the dates initially requested, it shall provide written notice 

by 3:00 p.m. (local time at the review location). A list of names of persons who 

will view the Source Code Material will be provided to the Producing Party in 

conjunction with any written (including email) notice requesting inspection. The 

Receiving Party shall maintain a daily log of the names of persons who enter the 

rooms to view the Source Code and when they enter and depart. The Producing 

Party shall be entitled to have a person observe all entrances and exits from the 

room containing the Source Code Computer(s), and a copy of the log upon request.

(e) The producing Party shall provide the receiving Party with information explaining 

how to start, log on to, and operate the Source Code Computer(s) in order to access

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 7 of 24 PageID #: 1026
8

the produced Source Code Material on the Source Code Computer(s);

(f) The producing Party will produce Source Code Material in computer searchable 

format on the stand-alone computer(s) as described above, and upon reasonable 

request from the Receiving Party will make reasonable efforts to install reasonable 

search and analysis tools requested by the Receiving Party. If these tools require a 

license which is not previously held by the Producing Party, the Receiving Party 

shall provide the Producing Party with a CD or DVD containing the licensed 

software tool(s) at least five (5) days in advance of the date upon which the 

Receiving Party wishes to have the licensed software tool(s) available for use on 

the Source Code Computer(s);

(g) Source code reviewers are permitted to bring paper and pen to take notes while in 

the source code review room. The Receiving Party’s outside counsel and/or expert 

shall be entitled to take notes relating to the Source Code Material but may not copy 

any portion of the Source Code Material into notes. For avoidance of doubt, 

Receiving Party’s Outside Counsel and/or experts may include file names, line 

numbers, the names of functions and variables, and quotations from “code 

comments” in their notes. Any notes relating to the Source Code Material will be 

treated as “RESTRICTED CONFIDENTIAL – SOURCE CODE.” The Producing 

Party may visually monitor the activities of the Receiving Party’s representative(s) 

during any Source Code review, but only to ensure that there is no unauthorized 

recording, copying, or transmission of the Source Code Material. In so doing, the 

Producing Party will not monitor, listen in on, or otherwise inhibit the Receiving 

Party's privileged communications or note-taking in the Source Code Review 

Room, and the Producing Party's supervision will not, by itself, be deemed to cause 

any waiver or other loss of any privilege covering such notes or communications. 

Unless otherwise agreed in advance by the Parties in writing, following each 

inspection, the Receiving Party’s outside counsel and/or experts shall remove all 

notes, documents, and all other materials from the room that may contain work 

product and/or attorney-client privileged information. The Producing Party shall 

not be responsible for any items left in the review room following each inspection 

session.

(h) Access to Protected Material designated RESTRICTED CONFIDENTIAL -

SOURCE CODE shall be limited to outside counsel and up to seven (7) outside 

consultants or experts (i.e., not existing employees or affiliates of a Party or an 

affiliate of a Party) retained for the purpose of this litigation and approved to access 

such Protected Materials pursuant to Paragraph 6(d) above. A Receiving Party may 

include excerpts of Source Code Material in a pleading, exhibit, expert report, 

discovery document, deposition transcript, other Court document, subject to the 

limitations of Footnote 3 below, provided that the Source Code Documents are 

appropriately marked under this Order, restricted to those who are entitled to have 

access to them as specified herein, and, if filed with the Court, filed under seal in 

accordance with the Court’s rules, procedures and orders. In no case shall any 

information designated as RESTRICTED CONFIDENTIAL SOURCE CODE by

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 8 of 24 PageID #: 1027
9

a Defendant or by any future intervenor be provided to any other Defendant, 

intervenor, or their counsel, by any Party or counsel absent explicit written 

agreement from the Producing Party;

(i) To the extent portions of Source Code Material are quoted in a Source Code 

Document, either (1) the entire Source Code Document will be stamped and treated 

as RESTRICTED CONFIDENTIAL SOURCE CODE or (2) those pages containing 

quoted Source Code Material will be separately stamped and treated as 

RESTRICTED CONFIDENTIAL SOURCE CODE;

(j) Except as set forth in paragraph 12(l) below, no electronic copies of Source Code 

Material shall be made without prior written consent of the producing Party, except 

as necessary to create documents which, pursuant to the Court’s rules, procedures 

and order, must be filed or served electronically.3 The Receiving Party shall only 

make additional paper copies of selected excerpts of the Source Code if such 

additional copies are reasonably necessary for any filing with the Court or service 

of any pleading or other paper on any Party. No paper copies of excerpts of Source 

code shall be made by the Receiving Party without the express written permission 

of the Producing Party;

(k) The receiving Party shall be permitted to request that the Producing Party make a 

reasonable number of printouts and photocopies of Source Code Material, all of 

which shall be designated and clearly labeled “RESTRICTED CONFIDENTIAL 

SOURCE CODE.” The Producing Party will comply with all such requests for 

printouts within five (5) business days of the request (and shall endeavor to provide 

them in 3 business days), and the Receiving Party shall maintain a log of all such 

files that are printed or photocopied. Producing Party will strive to accommodate 

shorter turnaround requests. In no event may the Receiving Party print any 

continuous block of Source Code that results in more than 35 continuous printed 

pages, or an aggregate total of more than 1500 pages, for each Producing Party’s 

Source Code, during the duration of the case without prior written permission of 

the Producing Party, and the Producing Party shall not unreasonably withhold or 

delay such permission. The parties will work in good faith if any party needs to 

print additional pages. The printed pages shall constitute part of the Source Code 

Material produced by the Producing Party in this action. At the Receiving Party’s 

request, up to three additional sets (or subsets) of printed source Code may be 

requested, and the Producing Party shall provide the additional sets by overnight 

mail or other mutually agreed method within three business days after receiving 

the request;

(l) The Receiving Party shall not create any electronic or other images of any printed 

pages of Source Code or any other documents or things reflecting Source Code

3 For clarification, a party may identify source code file names, function names, and variable names 

in notes. To the extent a party feels the need to include an excerpt(s) of Source Code in expert reports 

and/or infringement contentions for a claim element(s), it shall be required to identify the relevant 

source code as specifically as possible in the expert reports and/or infringement contentions, and in 

no event shall any source code excerpt be more than 15 contiguous lines of code. A Receiving Party 

may prepare and serve such expert reports and infringement contentions electronically.

Material that have been designated by the Producing Party as “RESTRICTED 

CONFIDENTIAL SOURCE CODE,” except as necessary to create documents 

which, pursuant to the Court’s rules, procedures and order, must be filed or served 

electronically. A Receiving Party may include excerpts of “RESTRICTED 

CONFIDENTIAL SOURCE CODE” in a pleading, exhibit, expert report, 

discovery document, deposition transcript, other Court document, provided that 

the Source Code Documents are appropriately marked under this Order, restricted 

to those who are entitled to have access to them as specified herein, and, if filed 

with the Court, filed under seal in accordance with the Court’s rules, procedures 

and orders. Any such excerpt of Source Code Material shall not exceed 15 

continuous lines and shall not exceed 45 lines per source code file without prior 

written approval by the Producing Party, and the Producing Party shall not 

unreasonably withhold or delay such approval. For clarity, should such printouts 

or photocopies be in electronic media,such media shall be labeled “RESTRICTED 

CONFIDENTIAL SOURCE CODE” and shall continue to be treated as such;

(m) If the Receiving Party’s outside counsel, consultants, or experts obtain printouts or 

photocopies of Source Code Material, the receiving Party shall ensure that such 

outside counsel, consultants, or experts keep the printouts or photocopies in a 

secured locked area in the offices of such outside counsel, consultants, or expert. 

The receiving Party may also temporarily keep the printouts or photocopies at: (i) the 

Court for any proceeding(s) relating to the Source Code Material, for the dates 

associated with the proceeding(s); (ii) the sites where any deposition(s) relating to 

the Source Code Material are taken, for the dates associated with the deposition(s); 

and (iii) any intermediate location reasonably necessary to transport the printouts or 

photocopies (e.g., a hotel prior to a Court proceeding or deposition); and

(n) A Producing Party’s SourceCode Material may only be transported by the receiving 

Party at the direction of a person authorized under Paragraph 12(h) above to another 

person authorized under paragraph 12(h) above, on paper via hand carry, Federal 

Express or other similarly reliable courier. Source Code Material shall be 

maintained at all times in a secure location under the direct control of counsel or 

authorized individuals listed under Paragraph 6(d) responsible for maintaining the 

security and confidentiality of the DESIGNATED MATERIALS and in a manner 

that prevents duplication of or unauthorized access to the Source Code Material, 

including, without limitation, storing the Source Code Material in a locked room 

or cabinet at all times, when it is not in use. When in transport from one of the 

above approved locations to another, the Receiving Party shall take reasonable 

measures to secure the Source Code Material. Source Code Material may not be 

transported or transmitted electronically over a network of any kind, including a 

LAN, an intranet, or the Internet. Source Code Material may only be transported 

outside the offices of outside counsel for the Receiving Party or of the experts 

and/or consultants who have been approved to view the Source Code for the 

purpose of Court proceeding(s) or deposition(s) as set forth in paragraph 12(m) 

above and is at all timessubject to the transport restrictionsset forth herein. But, for 

those purposes only, the Source Code Materials may be loaded onto a stand-alone 

computer.

(o) A producing Party may, at its election, prohibit a receiving Party’s source code

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 10 of 24 PageID #: 1029
11

reviewer(s) from bringing electronic devices (other than medical devices) into the 

room containing the stand-alone computer. If the producing Party so elects, the 

producing Party must provide (1) a separate, secure, and substantially private 

workspace convenient to the review room for use by the receiving Party’s 

reviewer(s) to store and use electronic devices; and (2) a note-taking laptop located 

in the review room. The note-taking laptop must be equipped with Microsoft Word 

and Microsoft OneNote, or (after reasonable notice to the reviewing Party) 

equivalent software. The producing Party must provide for any reviewer to load 

notes, including electronic documents, onto the note-taking laptop prior to a review 

session and to retrieve notes from the note-taking laptop after a review session, for 

example by supervised use of a USB storage device. All notes, whether electronic 

or otherwise, will remain protected as work product. The note-taking laptop 

computer will not track, keep any file histories of, or otherwise record notes 

generated by the Reviewing Party, including through any keyloggers, tracking 

software, or recording software. For the avoidance of doubt, no reviewer may at 

any time copy any portions or sections of Source Code Material into either 

electronic or paper notes and counsel for the reviewing Party shall instruct its 

reviewer(s) not to copy or include any portion or section of Source Code Material 

in either electronic or paper notes.

(p) For depositions, five (5) business days before the date of the deposition, the 

Receiving Party shall notify the Producing Party about the Source Code printouts 

it wishes to use at the deposition, and which the Producing Party shall make 

available to the witness at the deposition. The Producing Party shall endeavor to 

accommodate requests made on shorter notice. Absent other agreement among the 

parties, the Receiving Party will ensure that its counsel have any needed Source 

Code printouts, and the Producing Party will ensure its counsel and its witnesses 

have any needed Source Code printouts. In the event air travel is needed for a 

deposition, the Source Code Printouts shall be carried on and not placed in checked 

luggage by the traveling attorney or witness. Furthermore, for depositions of 

persons eligible to view Source Code Material, at least three weeks in advance of 

the deposition, the Receiving Party shall notify the Producing Party if the Receiving 

Party wishes to have the Producing Party make a Source Code Computer available 

at the deposition. Any deposition where a Source Code Computer is requested shall 

take place in person at a mutually agreed-upon location. The Producing Party is 

only required to prepare one additional Source Code Computer for use during 

depositions, and the parties agree to meet and confer regarding the appropriate 

scheduling of depositions to avoid any conflicts. During the deposition, the screen 

and/or contents of the Source Code Computer shall not be recorded. The Source 

Code Computer made available at the deposition shall include appropriate software 

analysis tools as discussed below, provided the Receiving Party has, at its expense, 

provided the supplier with a license for such software tool in sufficient time to have 

it properly loaded on the deposition source code computer.

13. Absent written consent of the Producing Party, no person on behalf of Plaintiff, including 

without limitation any outside consultant or expert of Plaintiff, who reviews any other 

Party’s Protected Material that is designated RESTRICTED -- ATTORNEYS’ EYES 

ONLY and/or RESTRICTED CONFIDENTIAL SOURCE CODE (collectively 

“HIGHLY SENSITIVE MATERIAL”), who obtains, receives, has access to, or otherwise 

learns, in whole or in part, the other Party’s HIGHLY SENSITIVE MATERIAL under this 

Order shall prepare, prosecute, supervise, or assist in the preparation or prosecution of any 

patent application, or engage in any Prosecution Activity, pertaining to the field of the 

invention of the patents-in-suit, including but not limited to 3GPP 5G NR beamforming 

and/or 3GPP Coordinated Multipoint Transmission and Reception and beamforming 

technologies, during the pendency of this Action and for one year after its conclusion, 

including any appeals. To ensure compliance with the purpose of this provision, Plaintiff 

shall create an “Ethical Wall” between those persons with access to HIGHLY SENSITIVE 

MATERIAL and any individuals who, on behalf of Plaintiff or its acquirer, successor, 

predecessor, or other affiliate, prepare, prosecute, supervise or assist in the preparation or 

prosecution of any patent application on behalf of Plaintiff, or pertaining to the field of the 

invention of the patents-in-suit including but not limited to 3GPP 5G NR beamforming 

and/or 3GPP Coordinated Multipoint Transmission and Reception and beamforming 

technologies. For clarity and avoidance of doubt, outside counsel of any Defendant or 

future intervenor in this action are not subject to this Prosecution Bar if they have received 

any other Party’s non-technical CONFIDENTIAL information or non-technical 

RESTRICTED – ATTORNEYS’ EYES ONLY information other than through a violation 

of this Order.

14. Prosecution Activity shall mean any activity related to (i) the preparation or prosecution 

(for any person or entity) of patent applications relating to 3GPP 5G NR beamforming

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 12 of 24 PageID #: 1031
13

and/or 3GPP Coordinated Multipoint Transmission and Reception and beamforming 

technologies, or (ii) advising or counseling clients regarding the same, including but not 

limited to providing any advice, counseling, preparing, prosecuting, editing, amending 

and/or drafting of claims, for any patent application, reexamination, or reissue application 

before any domestic or foreign patent office. Nothing in this Paragraph shall prevent any 

attorney from sending non-confidential prior art to an attorney involved in patent 

prosecution for purposes of ensuring that such prior art is submitted to the U.S. Patent and 

Trademark Office (or any similar agency of a foreign government) to assist a patent 

application in complying with its duty of candor. Nothing in this provision shall prohibit 

any attorney of record in this litigation from discussing any aspect of this case that is 

reasonably necessary for the prosecution or defense of any claim or counterclaim in this 

litigation with his/her client. To avoid any doubt, this Paragraph does not restrict any 

recipient of HIGHLY SENSITIVE MATERIAL from participating in a reissue protest, ex 

parte reexamination, inter partes reexamination, inter partes review, or other form of postgrant review provided they (1) do not rely upon or use, directly or indirectly, the producing 

Party’s HIGHLY SENSITIVE MATERIAL in those proceedings and (2) do not advise on, 

consult on, prepare, draft, or edit any amendment to specifications or claims in those 

proceedings.

to have access thereto to any person who is not authorized for such access under this Order. 

The Parties are hereby ORDERED to safeguard all such documents, information and 

material to protect against disclosure to any unauthorized persons or entities.

17. Nothing contained herein shall be construed to prejudice any Party’s right to use any 

DESIGNATED MATERIAL in taking testimony at any deposition or hearing provided that 

the DESIGNATED MATERIAL is only disclosed to a person(s) who is: (i) eligible to have 

access to the DESIGNATED MATERIAL by virtue of his or her employment with the

producing Party or from the Court.

the Parties from introducing any DESIGNATED MATERIAL into evidence at the trial of 

this Action, or from using any information contained in DESIGNATED MATERIAL at 

the trial of this Action, subject to any pretrial order issued by this Court.

Case 2:23-cv-00202-JRG-RSP Document 44 Filed 09/05/23 Page 15 of 24 PageID #: 1034
16

Party may apply to the Court for relief. Upon any such application to the Court, the burden 

shall be on the designating Party to show why its classification is proper. Such application 

shall be treated procedurally as a motion to compel pursuant to Federal Rules of Civil 

Procedure 37, subject to the Rule’s provisions relating to sanctions. In making such 

application, the requirements of the Federal Rules of Civil Procedure and the Local Rules 

of the Court shall be met. Pending the Court’s determination of the application, the 

designation of the designating Party shall be maintained.

accordance with the terms of this Order shall be advised by counsel of the terms of this

(“Third Parties”) and in the event that such Third Parties contended the discovery sought 

involves trade secrets, confidential business information, or other proprietary information,

designate as “CONFIDENTIAL” or “RESTRICTED -- ATTORNEYS’ EYES ONLY” or 

“RESTRICTED CONFIDENTIAL SOURCE CODE” any documents, information or 

other material, in whole or in part, produced or given by such Third Parties. The Third

material so produced or given shall be treated as “RESTRICTED – ATTORNEYS’ EYES 

ONLY” in accordance with this Order.

summaries, descriptions, and excerpts or extracts thereof (excluding excerpts or extracts 

incorporated into any privileged memoranda of the Parties and materials which have been

returned to the producing Party or be destroyed. The receiving Party shall verify the return 

or destruction by affidavit furnished to the producing Party, upon the producing Party’s 

request.

and the failure to object to a designation at a given time shall not preclude the filing of a 

motion at a later date seeking to impose such designation or challenging the propriety 

thereof. The entry of this Order and/or the production of documents, information and 

material hereunder shall in no way constitute a waiver of any objection to the furnishing 

thereof, all such objections being hereby preserved.

this Order and has raised the question of violation or potential violation with the opposing 

party and has been unable to resolve the matter by agreement may move the Court for such 

relief as may be appropriate in the circumstances. Pending disposition of the motion by the 

Court, the Party alleged to be in violation of or intending to violate this Order shall

to be submitted for approval by the Court.

this Protective Order, including any unintentional or inadvertent disclosure, the Party 

responsible for having made such disclosure, and each Party with knowledge thereof, shall 

immediately notify counsel for the Producing Party and provide to such counsel all known 

relevant information concerning the nature and circumstances of the disclosure. The 

responsible disclosing Party shall also make every effort to further prevent unauthorized 

disclosure, including retrieving all copies of the Protected Information from the 

recipient(s) thereof, and securing the agreement of the recipients not to further disseminate 

the Protected Material in any form. Compliance with the foregoing shall not prevent the 

Producing Party from seeking further relief from the Court. Unauthorized or inadvertent 

disclosure does not change the status of Protected Material or waive the right to hold the 

disclosed document or information as Protected.

Order to allow disclosure of DESIGNATED MATERIAL to additional persons or entities

Party or nonparty, and their counsel, who has produced such documents and include a copy 

of the subpoena or request with such notice, and (c) provide each such Producing Party or 

nonparty with an opportunity to object to the production of such documents. The person or 

entity to whom the subpoena or other request is directed shall not take any position 

concerning the propriety of such request or subpoena or the discoverability of the 

information sought thereby that is adverse to any Producing Party or producing nonparty 

opposing the request for production of such documents or materials. If a Producing Party 

or nonparty does not take stepsto prevent disclosure ofsuch documents within ten business 

days of the date written notice is given, the Party to whom the referenced subpoena is 

directed may produce such documents in response thereto, but shall take all reasonable 

measures to have such documents treated in accordance with terms of this Protective 

Order.

34. This Order is not a waiver of any applicable privilege or any objection that might be raised 

as to a discovery request or the admissibility of evidence. Nothing in this Protective Order 

shall be construed to prevent counsel from advising their clients with respect to this case 

based in whole or in part upon Protected Information, provided counsel does not disclose

the Protected Information itself except as provided in this Order.

recipients of the Protected Information for enforcement of the provision of this Agreed 

Protective Order following termination of this litigation. All disputes concerning Protected

38. The Producing Party may redact PROTECTED PERSONAL DATA: (i) if the 

PROTECTED PERSONAL DATA is not responsive to the Receiving Party’s discovery 

request; (ii) if the Parties have agreed that the Producing Party need not produce this 

PROTECTED PERSONAL DATA; or (iii) if the PROTECTED PERSONAL DATA is, 

by its nature, particularly sensitive or relates to criminal convictions and offences, unless 

the disclosure of such PROTECTED PERSONAL DATA is strictly relevant to this 

litigation.

39. If the Receiving Party learns that, by inadvertence or otherwise, it has disclosed 

PROTECTED PERSONAL DATA to any person not authorized herein, the Receiving 

Party must without undue delay and not later than within 48 hours notify the Producing 

Party of the unauthorized disclosure.

40. If the disclosure of PROTECTED PERSONAL DATA to the Receiving Party leads to a 

transfer of personal data from a country in the EU/EEA to a country outside the EU/EEA, 

the Producing Party and the Receiving Party (and any additional receiving PROTECTED 

PERSONAL DATA) shall enter into the standard contractual clauses for the transfer of 

personal data to third countries pursuant to Regulation (EU) 2016/679 of the European 

Parliament and of the Council adopted by the EU Commission on 4 June 2021 (Module 

One: Transfer controller to controller) (implementing decision (EU) 2021/914), prior to

States if it is reasonably necessary for a deposition in this litigation taken in a foreign 

country. The restrictions contained within this paragraph may be amended through the 

consent of the producing Party to the extent that such agreed to procedures conform with 

applicable export control laws and regulations.
