An Attorneys’ Eyes Only protective order is the top tier of a litigation confidentiality order: it restricts the most sensitive documents exchanged in a lawsuit so that only the opposing side’s outside lawyers and a small group of approved people can see them. The opposing party itself — its executives, employees, and often its in-house counsel — is shut out. Federal courts use this tool when a lawsuit forces competitors to hand over trade secrets, pricing data, customer lists, or similar material that could cause real competitive harm if the wrong people saw it.
Where AEO Sits in a Protective Order
Most protective orders in federal civil cases set up at least two tiers of confidentiality. The lower tier, usually labeled “Confidential,” covers sensitive business information that a limited number of the opposing party’s employees can review, typically people with a direct role in overseeing the lawsuit. The higher tier, labeled “Highly Confidential — Attorneys’ Eyes Only,” is reserved for information so sensitive that even limited employee access would create too great a risk of competitive harm.
AEO is not the default. A document qualifies for the higher designation only when disclosure, even to a small group of the opposing party’s people, would create a substantial risk of serious harm that less restrictive treatment cannot prevent. Current pricing structures, customer lists a competitor could poach from, unreleased product roadmaps, and confidential merger plans are the kinds of materials that typically justify it. If ordinary “Confidential” treatment adequately protects the information, AEO is overkill and a court can strip the designation.
Who Can See AEO Materials
The whole point of an AEO designation is a short access list. Wording varies by case, but federal model protective orders converge on a similar group of permitted viewers:
- Outside counsel of record, along with associates, paralegals, and litigation support staff at their firm who need access for the work.
- Retained experts and consultants hired specifically for the litigation, provided they sign an acknowledgment agreeing to be bound by the order.
- Witnesses who authored or received the document, or who are being prepared for deposition or trial testimony. They can usually view the material temporarily but cannot keep a copy.
- The court and its staff, including judges, clerks, and court reporters.
- Litigation vendors such as copying services, e-discovery platforms, and jury consultants, after signing the required acknowledgment.
Conspicuously absent is the opposing party itself. Company officers, directors, employees, and frequently in-house counsel cannot see AEO materials. The restriction exists because these people make business decisions. If a marketing director at Company A reviews Company B’s customer list during litigation, there is no realistic way to un-know that information once the case ends. The risk of even subconscious competitive use is why courts draw this hard line.
The In-House Counsel Question
One of the sharpest practical disputes around AEO orders involves in-house lawyers. They are licensed attorneys, often deeply involved in managing the case. Shutting them out of key documents can hamper the party’s ability to prepare. But in-house lawyers also advise on pricing, product design, and competitive strategy, which is precisely why the AEO wall exists.
Courts evaluate in-house counsel access using the “competitive decisionmaker” test, rooted in the Federal Circuit’s decision in U.S. Steel Corp. v. United States. The inquiry focuses on whether the lawyer participates in decisions like pricing, product development, or bid review, where a competitor’s confidential information could influence the outcome. Courts also look at how separated the lawyer’s litigation work is from the company’s competitive operations, and the level of supervision the lawyer is under.1U.S. Government Accountability Office.

If an in-house attorney can show they play no role in competitive decisionmaking, some protective orders create a carve-out allowing access after the producing party is notified and given a chance to object. The burden sits on the requesting side, and courts take it seriously. An in-house lawyer who regularly sits in on pricing meetings is almost certainly going to be excluded.
How a Document Gets the AEO Label
The producing party decides which documents warrant AEO treatment. Each page of a physical document, or each digital file, gets stamped or labeled with the “HIGHLY CONFIDENTIAL — ATTORNEYS’ EYES ONLY” legend. That label is the receiving party’s notice that heightened access restrictions apply.
The designation is provisional. It reflects the producing party’s good-faith judgment that the material contains information whose disclosure to the opposing party’s people would cause serious competitive harm that less restrictive treatment cannot avoid. Producing parties are expected to make document-by-document assessments. Slapping AEO on an entire production without reviewing individual documents is the fastest way to lose credibility with the court and have designations stripped. A party must show more than just being a competitor of the receiving party; it needs to articulate the specific harm that would flow from broader disclosure.
How the Order Gets Entered
In most cases, the parties negotiate a protective order themselves and present it to the court as a stipulated order. The judge still has to sign it, and signing requires a finding that “good cause” supports the restrictions. A filed stipulation alone is not enough; the order only takes effect once the court issues it.2Federal Judicial Center. Confidential Discovery: A Pocket Guide on Protective Orders
If the parties cannot agree, either side can file a motion under Federal Rule of Civil Procedure 26(c), which authorizes the court to issue protective orders for good cause to shield a party from “annoyance, embarrassment, oppression, or undue burden or expense.” Among the specific protections the rule lists: requiring that a trade secret or other confidential commercial information “not be revealed or be revealed only in a specified way.”3Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery That language is the statutory hook for every AEO designation.
Many federal courts publish model protective orders with AEO provisions already drafted. Parties often start from one of these templates and negotiate case-specific changes. The AEO tier can be built into a broader blanket protective order so the producing party can provisionally designate specific documents at the higher level as it turns them over, without needing a separate court ruling on each one.2Federal Judicial Center. Confidential Discovery: A Pocket Guide on Protective Orders
Challenging an AEO Designation
If you receive an AEO designation you think is overbroad, every protective order includes a process to push back. The challenge typically unfolds in three steps.
First, the challenging party sends written notice identifying each document it disputes and explaining why the AEO label is unwarranted. Second, the parties are required to meet and confer in good faith to try to resolve the dispute without the judge. Many protective orders specify that this must be a real conversation, not just an exchange of letters.4United States District Court Northern District of California. Model Protective Order for Highly Sensitive Confidential Information in Patent Cases
Third, if the parties remain at an impasse, the designating party files a motion asking the court to uphold the designation. The burden of proof falls on the party that applied the AEO label, not on the party challenging it. The designating party must demonstrate “good cause” under Rule 26(c), which courts have interpreted to require showing a “clearly defined and serious injury” supported by specific examples, not vague assertions.3Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Broad claims that documents are “competitively sensitive” without explaining how disclosure would actually hurt the business will not survive scrutiny.
Courts weigh the designating party’s risk of harm against the receiving party’s need to use the information to litigate effectively. This is where over-designation backfires. A party that labels everything AEO forces its opponent to litigate with one hand tied, and judges notice. The practical consequence is that the court may downgrade the designation to ordinary “Confidential” or remove the restriction entirely.
Handling and Storing AEO Materials
Receiving AEO materials imposes real obligations on outside counsel. Physical documents need to be stored in locked cabinets, separate from general case files. Electronic files should live on password-protected systems with access limited to people on the approved list. Copies should be made only when necessary for the litigation, such as providing a working set to a retained expert who has signed the required acknowledgment.
Any sharing of AEO materials with someone not on the approved list is a violation of the court’s order, full stop. That includes well-meaning situations like forwarding a document to your client so they can help you understand it. The restrictions apply equally to information derived from the materials. You cannot read a competitor’s pricing model and then verbally relay the numbers to your client over the phone.
Penalties for Violating an AEO Order
A protective order is a court order, and violating it carries real consequences. Under Federal Rule of Civil Procedure 37(b), a court confronted with a discovery order violation can treat disputed facts as established against the violating party, bar it from supporting or opposing certain claims, strike its pleadings, enter a default judgment, or hold the offender in contempt. Contempt opens the door to additional sanctions, including possible jail time for individuals.5Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
The rule also requires the violating party or its attorney, or both, to pay the other side’s reasonable expenses, including attorney’s fees caused by the violation, unless the failure was substantially justified or an award would be unjust. That fee-shifting provision is not discretionary.5Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions And because AEO violations often involve a competitor gaining access to trade secrets, the producing party may also pursue a separate claim for misappropriation, which carries its own damages.
What Happens When the Case Ends
AEO designations do not expire with the verdict. Protective orders typically require that all AEO documents and copies be either returned to the producing party or destroyed within a set period after the litigation concludes, including any appeals. Sixty days is a common timeframe, though some orders allow 90 days or longer.1U.S. Government Accountability Office. Guide to GAO Protective Orders
Destruction is not just tossing files in the trash. The party disposing of materials must certify in writing to the other side that destruction has occurred. The obligation covers everything: physical documents, electronic copies, backup files, and any notes or work product that reproduces the protected information. Some orders let counsel keep a single archival copy of court filings that reference protected material, but only under the continuing restrictions of the order.
Holding onto AEO materials past the deadline without authorization is itself a violation and subject to the same sanctions. If both sides agree, the retention period can be extended, but that agreement needs to be documented.
