IN THE UNITED STATES DISTRICT COURT 

FOR THE EASTERN DISTRICT OF TEXAS 

UNITED STATES OF AMERICA, 

v. 

KYLE CARTER

Defendant

 Case No. 4:23-cr-225 

Hon. Amos L. Mazzant, III 

VIVATURE, INC.’S NOTICE OF OPPOSITION TO DISCLOSURE OF ITS 

PRIVILEGED MATERIAL AND PARTIALLY OPPOSED REQUEST FOR 

DISCLOSURE 

TO THE HONORABLE AMOS L. MAZZANT: 

Vivature, Inc. (“Vivature”), by and through undersigned counsel, respectfully provides 

Notice of its Opposition to any attempt by the Government to introduce as evidence in the trial in 

this matter any document or communication protected by Vivature’s attorney-client privilege 

and/or the attorney work-product doctrine. Vivature further respectfully requests that the 

Government be ordered to identify any exhibits it intends to introduce or testimony it intends to 

elicit in the trial in this matter that would otherwise be protected by Vivature’s attorney-client 

privilege and/or the attorney work-product doctrine so that Vivature may have an opportunity to 

be heard in order to protect its privilege. 

I. The Government’s Notification of Alleged Waiver. 

In the course of an email exchange between the Government and the undersigned counsel 

regarding since-withdrawn trial subpoenas, the Government indicated for the first time on the night 

of August 12 that it “understand[s] there is a subject matter waiver with respect to Vivature’s 

privilege as it pertains to the athletic training portion of its business” because of “recent disclosures 

regarding Matt Lipton.”1

 Given that this occurred in the context of a discussion regarding other 

1 See Exhibit 1. The portions of the email exchange referring to other items under discussion between the Government 

and undersigned counsel have been redacted for this public filing. Mr. Lipton previously served as outside counsel 

Case 4:23-cr-00225-ALM-AGD Document 112 Filed 08/15/24 Page 1 of 27 PageID #: 1135
2 

issues related to Dr. Carter’s trial, Vivature can only assume that the Government intends to utilize 

some documents and/or testimony regarding Mr. Lipton and/or his otherwise protected advice and 

communications during the present trial. 

The undersigned counsel has now responded to the Government three times (August 12,2

August 13,3

 and August 144) seeking clarifying information from the Government regarding the 

nature of these alleged disclosures, who made them, how and why those constitute subject-matter 

waiver by Vivature for its privilege over a portion of its business for a decade-long period 

(including up to eight (8) years after Mr. Lipton ceased providing services to Vivature), and what 

use the Government intends to make of these otherwise privileged communications. The 

Government has failed to provide any response to any of these requests for information. 

II. Vivature has Neither Intentionally nor Inadvertently Waived its 

Attorney-Client and/or Attorney Work Product Doctrine Privileges. 

As the Eastern District has long recognized, “subject matter waivers should be 

‘construe[d] ... narrowly while accommodating fundamental fairness.’” DataTreasury Corp. v. 

Wells Fargo & Co., No. 2:06-CV-72 DF, 2009 WL 10679940, at *3 (E.D. Tex. Nov. 13, 2009)

(quoting Hunter v. Copeland, No. 03–2584, 2004 WL 2472487, at *2 (E.D. La. Nov. 1, 2004) 

(citing U.S. v. Skeddle, 989 F.Supp. 917, 919 (N.D. Ohio 1997))). Here, despite the Government’s 

vague reference to “recent disclosures” in its August 12, 2024 email, Vivature has neither 

intentionally nor inadvertently waived its privilege in any respect, let alone regarding any advice 

Mr. Lipton may have provided from approximately 2014-2016. Certainly, Vivature is not engaged 

(including periods as outside general counsel) to Vivature from approximately 2014 through 2016, providing advice 

on a number of matters, including the athletic training portion of its business. 

2 See Exhibit 2. 

3 See Exhibit 3. 

4 See Exhibit 4. 

Case 4:23-cr-00225-ALM-AGD Document 112 Filed 08/15/24 Page 2 of 27 PageID #: 1136

in a “selective waiver of privilege” that would provide it with an “unfair advantage” necessitating 

the Court’s review under Federal Rule of Evidence 502(a). Id. (citing Equity Residential v. Kendall 

Risk Mgmt. Co., 246 F.R.D. 557, 568 (N.D. Ill. 2007); Wunderlich–Malec Sys., Inc. v. Eisenmann 

Corp., No. 05–c–04343, 2006 WL 3370700 (N.D. Ill. Nov. 17, 2006)). 

III. Conclusion 

With the trial in this matter ongoing and the Government’s failure to respond to Vivature’s 

multiple requests for clarification, Vivature is providing this Notice of Opposition to ensure that 

Vivature’s privilege is protected. Vivature respectfully requests that the Court order the 

Government to identify any exhibits it intends to introduce or testimony it intends to elicit in the 

trial in this matter that would otherwise be protected by Vivature’s attorney-client privilege and/or 

the attorney work-product doctrine. Vivature further respectfully requests that the Government be 

ordered to identify such exhibits and/or testimony sufficiently in advance that Vivature may have 

the opportunity to object and a hearing be held to establish the basis for the Government’s alleged 

waiver.

Subject: RE: Trial Subpoenas - USA v. Carter 4:23CR225

Anand, Adrian, and Glenn: 

With Dr. Carter’s trial starting today, please let me know as soon as possible the answers to the questions 

below. Namely: 

• What disclosures you think have been made implicating Vivature’s privilege? 

• Who made those disclosures? 

• How those disclosures constitute a subject matter waiver “with respect to Vivature’s privilege as it pertains to 

the athletic training portion of its business”? 

Since Dr. Carter’s trial is starting today and testimony could start as early as this afternoon, if I have not heard back from 

y’all by this 4 pm this afternoon, I will be forced to file a notice to the Court advising them of Vivature’s opposition to 

any alleged subject matter waiver and requesting the identification of any exhibits you propose to introduce in Dr. 

Carter’s trial where Vivature’s privilege was allegedly “waived,” and a hearing on the same (if necessary). 

Kind regards, 

Ryan

Anand, Adrian, and Glenn: 

Finally, for the avoidance of doubt after my responses below last night and this morning, Vivature does not agree that 

there has been any intentional waiver of any of its privileges nor that there has been a subject matter waiver with 

respect to Matt Lipton and/or the athletic training portion of its business. 

Thanks,

 Anand, 

Just following up on the below because I’m trying to understand what disclosures you think have been 

made, by whom, and how those constitute a subject matter waiver. 

Thanks,

Anand, 

 

Thank you, couple of items below: 

1.

2.

3. What disclosures regarding Matt Lipton are you referencing? And what subject 

matter waiver do you understand there to be regrading Mr. Lipton and the 

athletic training portion of Vivature’s business? 

 

Thanks,
