The boundary that protects both innovation and mobility

The Philips prosecution gives a precise answer to the question this series has followed: an employee’s valuable experience is not automatically a former employer’s property, but specific information can become the subject of federal theft when it was kept secret, had value because it was secret, moved through an unauthorized route, and the required criminal purpose and knowledge can be proved. The final task is to use that answer as a practical boundary test. It must protect Philips’s investment in X-ray technology without treating every remembered skill, lawful disclosure, foreign competitor, or new employment relationship as criminal.

A boundary test that starts with information

The most reliable analysis begins with the information, not with the employee’s identity or the competitor’s nationality. A departing engineer may possess several things at once: general knowledge of a technical field, experience earned through years of work, confidential documents, a design or process, and memories of how a team solved a problem. The law does not give those things one legal status merely because they reside in the same person. A conclusion must keep them separate.

The first question is whether the claimed material is specific enough to evaluate. “Everything the engineer learned at Philips” is too broad to do the work of a trade-secret analysis. The relevant object might be a design, method, process, prototype, procedure, or other engineering information. Under the federal definition, it must also satisfy two conditions together: Philips must have taken reasonable measures to keep it secret, and the material must derive actual or potential independent economic value from not being generally known or readily ascertainable through proper means by someone who could obtain value from it.

Those gates protect both sides of the boundary. They prevent an employer from converting an entire field of knowledge into a permanent restraint on a worker. They also recognize that an information-based advantage can be real even when it is not a single dramatic formula. In the Philips setting, the DOJ described years of proprietary X-ray technology and information copied from internal databases. That is a concrete reason to examine specific technical material. It is not, from the public announcement alone, a reason to declare every engineering judgment or every item in a database a trade secret.

The second question is how the information was obtained, disclosed, or used. Authorized access for assigned work is not the same as authorization to copy material for a competing venture. Copying is not the same act as later disclosure. Using a particular document or process in new technical work is not the same as carrying general expertise into a new job. Recruiting colleagues may explain how a competing team formed, but recruitment alone does not identify a protected secret or establish an information-related offense.

The route matters because federal law treats improper means and lawful acquisition differently. Theft, misrepresentation, bribery, electronic espionage, and breach or inducement of a secrecy duty are examples of improper means. Reverse engineering, independent derivation, and other lawful means are excluded. A competitor can arrive at a similar product through its own work. Similarity may prompt an investigation, but it does not decide whether Philips information was misappropriated.

The third question is whether the facts support a criminal theory rather than only a dispute about confidentiality. Under the § 1832 model supplied by the statute and the Seventh Circuit pattern instruction, the government must prove the trade-secret status of the information, the defendant’s intent to convert it for someone else’s economic benefit, the defendant’s knowledge or belief about its status under the applicable instruction, a knowing unauthorized act or a properly charged attempt or conspiracy theory, the product-or-service connection to interstate or foreign commerce, and the intent or knowledge that the action would injure an owner. The standard is beyond a reasonable doubt for every required element.

That sequence matters more than any single dramatic fact. A competitor’s benefit does not prove the employee’s purpose. A confidential label does not prove statutory status. A foreign company does not prove economic espionage. A person’s knowledge of a technical field does not prove possession of a stolen document. The boundary is built from linked factual and mental-state propositions, not from the emotional force of the overall story.

The fourth question is which legal path the facts actually support. If the information is general know-how or the status is not established, the claim may stop there.
