Schei v. AT&T Inc.

Background

Network Apps, LLC, Kyle Schei, and John Wantz sued AT&T Mobility LLC and AT&T Services, Inc. for breach of contract and patent infringement. The plaintiffs alleged that AT&T used technology and proprietary information developed by Mya Number, whose assets were later assigned to Network Apps, in connection with AT&T’s NumberSync service. The opinion addresses only Defendants’ motion to disqualify Plaintiffs’ counsel; it does not decide the contract or patent claims.

AT&T sought to disqualify attorneys Kevin Cadwell, David Clonts, and Michael Reeder based on their earlier work for AT&T while employed at other firms. AT&T also sought to disqualify CCRT and its attorney Lisa Thomas through imputation of any conflict, and Ross LLP and its attorneys Peter Ross and Richard Schwartz based on their relationship with CCRT. AT&T did not seek to disqualify Lazare Potter & Giacovas LLP or David Potter.

Legal Standard

The court explained that federal courts have inherent authority to disqualify lawyers to protect the integrity of the adversarial process. Because disqualification can interfere with a party’s choice of counsel and can be used for tactical purposes, such motions are disfavored and require a high standard of proof. For successive representations, the moving party generally must show that it was the former client, that the prior and current matters are substantially related, and that the lawyer had access to, or was likely to have had access to, relevant privileged information.

A substantial relationship requires more than a common area of law or broad subject matter. The factual issues in the earlier and current matters must be identical, essentially the same, or otherwise closely connected. General knowledge of a former client’s business, policies, practices, or litigation strategy ordinarily is not enough.

The Court’s Analysis

The court held that AT&T had not shown a substantial relationship between the earlier matters handled by Cadwell, Clonts, or Reeder and the NumberSync technology and the ’728 Patent at issue in this case. The earlier matters involved broad topics such as text messaging, number provisioning, call interception, and other patent litigation. The court found that references to these general telecommunications concepts did not establish that the earlier cases involved the same technology or material facts as the current litigation.

The court also rejected AT&T’s argument that the attorneys’ lengthy relationships with AT&T, familiarity with AT&T’s operations and network architecture, or exposure to AT&T’s general litigation and settlement strategies required disqualification. Although the attorneys had exchanged privileged communications with AT&T in their earlier representations, AT&T did not show that those communications were relevant to this lawsuit or would give the attorneys an unfair litigation advantage.

AT&T pointed to the attorneys’ past interactions with anticipated witnesses, including McNamara and Buyukdura. The court found those interactions insufficient because AT&T did not show that the attorneys received relevant information about NumberSync, its predecessor technology, the ’728 Patent, or the twinning technology at issue. The attorneys stated that they had not previously worked on those subjects, and AT&T did not identify evidence contradicting those statements.

Because AT&T failed to establish a substantial relationship, it was not entitled to a presumption that relevant confidences had been shared. The court therefore concluded that AT&T also failed to prove that the attorneys had actually received relevant confidential information that could be used against AT&T.

Disposition

The court denied Defendants’ motion to disqualify Cadwell, Clonts, and Reeder. Because it found no conflict requiring their disqualification, it also denied the motion as to CCRT and Lisa Thomas. Because CCRT was not disqualified, the court denied the motion as to Ross LLP, Peter Ross, and Richard Schwartz. The court’s conclusion was stated as: “Defendants’ motion to disqualify Plaintiffs’ counsel is DENIED.” The court directed the parties to submit a joint letter about next steps and ordered the opinion filed under seal subject to the parties’ proposed redactions.
