EireOg v. Cisco — E.D. Tex. Limits Expert Testimony on Corporate Control, Bars Public-Policy Commentary Before Patent Trial

Background

EireOg Innovations Ltd. accuses products containing certain Intel chips, sold by Cisco, of infringing U.S. Patent 8,504,777. Cisco’s central defense is a license: Cisco argues that Intel’s membership in RPX Corporation grants an implied license under the ‘777 patent, because EireOg is functionally controlled by its Atlantic IP US and Atlantic IP Ireland parent entities (both of whom had dealings with RPX), making EireOg an “affiliate” or alter ego subject to RPX’s defensive patent pool. The parties filed cross-motions to exclude each other’s expert reports on the corporate-control question — John Ale (for Cisco) and Mark Chandler (for EireOg) — plus a Cisco motion to exclude Eric Chaffee, which EireOg mooted by stipulating it would not call Chaffee at trial.

The Court’s Holding

Magistrate Judge Payne granted the motions in part and denied them in part, narrowing both experts’ testimony to stay within Federal Rule of Evidence 702, 703, and 704 boundaries and consistent with the court’s prior report and recommendation on the license cross-motions.

Corporate-intent testimony is permitted. The court declined to treat Ale’s opinions about Atlantic IP’s motivations for forming EireOg as impermissible state-of-mind testimony. Under Network-1 Technologies v. Alcatel-Lucent, an expert may describe “actions typically taken under certain factual circumstances” without usurping the factfinder’s role — as long as the expert doesn’t opine on a specific party’s subjective intent. Ale’s testimony on why parties would enter particular agreements stays on the permissible side of that line.

Factual-background sections allowed. The court rejected EireOg’s argument that Ale’s “factual background” section was prejudicial expert endorsement of non-expert evidence. Rule 703 permits experts to rely on otherwise inadmissible evidence in forming opinions; reciting the factual basis is not the same as introducing that basis as substantive proof.

Chandler’s reliance on collateral RPX agreement and on Padian’s testimony is admissible. The court allowed Chandler to distinguish the Atlantic IP IE–RPX agreement from the Atlantic IP US–RPX agreement and to rely on Padian testimony in forming his “Control” definition, noting that any dispute over the weight of that reliance goes to cross-examination, not admissibility.

Already-decided license theories are out. Because the court’s prior report and recommendation already resolved the “affiliate,” “alter ego,” Daingean, and revenue-sharing theories in Cisco’s favor, both sides’ expert paragraphs that opine exclusively to those issues are stricken. The parties had largely conceded these withdrawals.

Fiduciary-duty testimony survives. The court allowed Chandler’s opinions on the fiduciary duties of seconded employees who sit on EireOg’s board while also serving Atlantic IP. Those opinions identify a legal duty rather than supply a legal conclusion, and they are relevant to whether control exists given the conflicting loyalties.

Public-policy and economic-effect testimony excluded. Chandler cannot offer the eight pages of his report that argue public policy in favor of the patent system or discuss the economic effects of patent assertion entities. That testimony risks jury confusion and unfair prejudice under Rule 403, especially because it strays from the specific corporate-control inquiry. The court left room for Chandler to describe “relevant functional aspects of the industry” within his expertise.

The court summarized the permitted scope of trial testimony for both Ale and Chandler: undisputed paragraphs, EireOg’s and related companies’ underlying business model and corporate structure, factual background and contract terms on the license dispute (especially the “Control” issue, with legal standards reserved for jury instructions), and typical actions taken for corporate governance under analogous circumstances.

Key Takeaways

• The NPE / RPX defense lives on. Cisco’s argument that Intel’s RPX membership carries over to EireOg through corporate control survives to trial, with expert testimony on both sides now scoped within the Network-1 boundary.
• Experts can opine on typical motivations — just not on a party’s specific state of mind. The practical takeaway from Judge Payne’s opinion is that an expert can tell the jury why parties generally enter affiliate-licensing agreements, structure power-of-attorney assignments, or second employees — so long as the testimony stops short of asserting what Atlantic IP or EireOg specifically intended.
• Policy arguments stay out. The court’s exclusion of Chandler’s eight pages on patent-system policy mirrors the growing skepticism in E.D. Tex. of efforts to use patent trials as platforms for broader NPE-versus-operating-company debates. EireOg‘s Motion in Limine No. 8 already barred that framing; the Daubert order closes the loop.
• Fiduciary duty to both master and servant. The court’s receptivity to Chandler’s fiduciary-duty line suggests a possible evidentiary pathway to breaking control-based license arguments: showing that individuals seconded from NPE parents to affiliates face structural conflicts that limit parental control in practice.

Why It Matters

Patent assertion entity structures increasingly rely on opaque parent-subsidiary arrangements precisely to keep patent-pool licenses from reaching the asserted claims. Cisco’s RPX defense in EireOg is one of several recent efforts to pierce that structure by treating the NPE subsidiary as an affiliate or alter ego of a licensed parent. Judge Payne’s order shows how trial courts are drawing the evidentiary line around expert testimony on that issue: industry-structure and typical-motivation opinions in, state-of-mind claims and policy advocacy out. Defendants pursuing these defenses will want both experts and demonstrative exhibits tuned to that framing before trial.
