Ed Nowogroski Insurance v. Rucker: Why Memorizing a Customer List Is Still Theft

Washington's Supreme Court held that a memorized customer list can be a trade secret. The form of the information is legally irrelevant under the UTSA.

When a departing salesperson walks out the door with the company’s client relationships stored in his head rather than in his briefcase, has he stolen anything the law will recognize? In Ed Nowogroski Insurance, Inc. v. Rucker, 137 Wn.2d 427, 971 P.2d 936 (Wash. 1999), the Supreme Court of Washington answered decisively. Deciding the case en banc on February 25, 1999, with Chief Justice Guy writing for the court, it held that the form of a trade secret, whether written on a page or committed to memory, is legally immaterial under the Uniform Trade Secrets Act.

The decision matters because the “I only memorized it” defense is one of the most common responses a trade secret plaintiff hears from a former employee. Nowogroski is the leading appellate authority rejecting that defense outright, and it reframes the entire inquiry around the nature of the information rather than the medium in which it traveled.

The facts and how the case rose

Ed Nowogroski Insurance, Inc. was a family-owned insurance agency. Michael Rucker, Darwin Rieck, and Jerry Kiser worked there as salesmen and account servicers, each with day-to-day access to the agency’s confidential customer information: who the clients were, what coverage they carried, their premium and commission histories, and their renewal dates. Rucker had signed an agreement acknowledging that the agency’s customer lists and file information were trade secrets and promising not to solicit business he had not personally produced.

The three men left to join a competitor, Potter Leonard and Cahan, Inc., and began soliciting Nowogroski’s clients. The agency sued under the Washington Uniform Trade Secrets Act, RCW 19.108.010 et seq., and won at trial. The court found that the customer information was a protectable trade secret and that the former employees had misappropriated it.

The trial court, however, drew a line that would become the heart of the appeal. As to Rieck’s solicitation of the agency’s fifty largest customers, it awarded no damages, reasoning that Rieck had not taken any written list but had simply remembered those clients. In the trial court’s view, memorized information fell outside the statute. The Court of Appeals reversed on that point, holding that the written-versus-memorized distinction had no legal significance, and the former employees and their new firm petitioned the Supreme Court on that single question.

The doctrinal frame: what the UTSA actually protects

The Uniform Trade Secrets Act defines a trade secret as information that “derives independent economic value, actual or potential, from not being generally known” and is “the subject of efforts that are reasonable under the circumstances to maintain its secrecy.” Nothing in that definition speaks to the physical form of the information. A trade secret can be a formula, a pattern, a compilation, a program, a device, a method, a technique, or a process.

The court seized on that statutory silence. Because the legislature protected “methods” and “techniques” alongside tangible compilations, the statute plainly contemplated intangible information. As the opinion put it, “The form of information, whether written or memorized, is immaterial under the trade secrets statute; the Uniform Trade Secrets Act makes no distinction about the form of trade secrets.” The question the statute asks is whether the information meets the two-part definition, not whether the misappropriator carried it out on paper or in his head.

This framing is important for the broader “what qualifies” question. A customer list is not automatically a trade secret. A list of names anyone could assemble from a phone book or a public directory derives no independent value from secrecy and would fail. What qualified in Nowogroski was a compiled body of client relationships and account details built up over years, kept confidential, and valuable precisely because a competitor did not have it. Once that compilation qualifies, the medium in which a departing employee reproduces it does not change its character.

Rejecting the old memory rule

The former employees leaned on an older strand of authority, the so-called memory rule, associated with the Restatement (Second) of Agency § 396 (1958). Under that view, an employee was free to use the names of customers he could remember, on the theory that memorized information had become part of the employee’s own general knowledge and experience.

The court rejected that rule as inconsistent with modern trade secret doctrine. It observed that “the weight of modern authority is that the manner of taking a trade secret is irrelevant,” and it aligned Washington with the Restatement (Third) of Unfair Competition § 42 (1995), which treats confidential customer information under uniform trade secret rules without regard to whether the employee wrote it down or memorized it. The court also pointed out that Washington had protected memorized customer information long before the UTSA, citing its own 1918 decision in John Davis & Co. v. Miller, so the result was not a departure but a continuation of settled state policy now codified by statute.

The court was careful to preserve the legitimate space for employee mobility. Trade secret law does not lock knowledge inside an employee’s skull. It does not reach the general skills, professional experience, and industry know-how that any worker accumulates and carries to a new job. What it reaches is the employer’s confidential compiled information. The line is not written versus remembered. The line is between the employee’s own general knowledge and the employer’s protected secret.

What the decision changed

Before Nowogroski, a defendant could plausibly argue in some jurisdictions that a clean exit, take nothing tangible, memorize the valuable clients, immunized the later solicitation. After Nowogroski, that argument has no traction in Washington and little elsewhere, because the decision has been cited across the country as the clearest articulation of the form-is-irrelevant rule.

Practically, the decision shifts the litigation onto the ground where trade secret cases belong: was the information a qualifying trade secret, did the employer take reasonable measures to protect it, and did the employee use it to compete? A defendant who says “but I only remembered it” is no longer contesting liability; he is at most describing how he committed the misappropriation. On remand, that is exactly what happened. The Court of Appeals disposition was affirmed, and the case went back for the trial court to recalculate Rieck’s damages to include the fifty large clients it had improperly carved out, with damages measured against the commissions generated by the misappropriated business.

Open questions

Nowogroski settled that form does not matter, but it left the harder line-drawing to future cases. The decision does not supply a bright-line test for separating an employee’s own general recollection of customers from the employer’s protected compilation. A salesperson who genuinely remembers a handful of longtime clients he personally cultivated stands differently from one who reconstructs an entire confidential book from memory, yet the opinion does not map the middle of that spectrum.

Nor does the case resolve how the reasonable-secrecy element interacts with information that lives mostly in employees’ heads. If the value of a client relationship is inherently memorable, how far must an employer go to show it took reasonable steps to keep the compilation secret? The court found reasonable measures present here, the trial court having found that the agency maintained the secrecy of its customer files by educating its staff and by providing employment manuals and employment agreements, but it did not set a floor for less formal workplaces.

Implications for employers and departing employees

  • Do not rely on the memorization defense. In Washington and the many jurisdictions that follow Nowogroski, walking out with the client book in your head is treated the same as walking out with a printout. If the underlying compilation qualifies, using it is misappropriation.

  • The fight is over whether the list qualifies, not the medium. Employers should build the record that their customer information derives value from secrecy and is genuinely confidential. Loose, publicly ascertainable lists remain unprotected regardless of how a competitor obtains them.

  • Reasonable secrecy measures still gate everything. Staff education, employment manuals, employment agreements, and clear designation of client data as protected, the measures the trial court credited Nowogroski with, are what let a plaintiff reach the memorization question at all.

  • Employees keep their general skill. The decision does not trap ordinary professional knowledge inside a former job. The safe path for a departing salesperson is to compete on his own general experience and independently known contacts, not to reconstruct the former employer’s confidential compilation.

Frequently asked questions

Does memorizing a customer list instead of copying it avoid liability? No. In Ed Nowogroski Insurance, Inc. v. Rucker, the Washington Supreme Court held that the form of the information is immaterial under the Uniform Trade Secrets Act. Using a memorized customer list can be misappropriation just as taking a written copy would be.

Does a customer list automatically qualify as a trade secret? No. The list must derive independent economic value from not being generally known and must be the subject of reasonable efforts to keep it secret. A list of readily ascertainable public names usually fails, while a compiled book of clients, policy details, and renewal dates can qualify.

Can an employee use general skill and knowledge learned on the job? Yes. Trade secret law protects the employer’s confidential compiled information, not the employee’s general skills, experience, or the identities of customers the employee can independently recall as a matter of ordinary professional knowledge.
