Case Summary
Honeywell International, Inc. v. OPTO Electronics Co., Ltd., decided by Fourth Circuit on April 29, 2025, resulted in a defendant win outcome. The Fourth Circuit affirmed the district court's grant of summary judgment to Honeywell, finding that OPTO Electronics failed to establish a claim for trade secret misappropriation under the Defend Trade Secrets Act (DTSA). The court reasoned that OPTO did not demonstrate that the information it sought to protect met the definition of a trade secret, specifically that it was not generally known or readily ascertainable, and that OPTO failed to show that Honeywell acquired the information through improper means. Therefore, the appellate court upheld the lower court's decision that no genuine dispute of material fact existed regarding the trade secret claim. The court held: The court held that information is not a trade secret under the DTSA if it is generally known or readily ascertainable, affirming that OPTO failed to show its alleged trade secrets met this threshold.. The court held that OPTO did not present sufficient evidence that Honeywell acquired the alleged trade secrets through improper means, a necessary element for a DTSA claim.. The court affirmed that a plaintiff must demonstrate both the existence of a trade secret and its misappropriation to succeed on a DTSA claim.. The court found that OPTO's failure to establish either the trade secret status of the information or its misappropriation by Honeywell warranted summary judgment for Honeywell.. The court concluded that OPTO's arguments regarding the alleged trade secrets were speculative and lacked the concrete evidence required to survive summary judgment.. This decision reinforces the high bar for plaintiffs seeking trade secret protection under the DTSA, emphasizing the need for specific evidence demonstrating that the information is not generally known or readily ascertainable. Businesses must be diligent in documenting and protecting their proprietary information to qualify for legal recourse.

Legal Tests Applied
Trade Secret Misappropriation under the Defend Trade Secrets Act (DTSA)
Elements: The existence of a trade secret · Misappropriation of the trade secret
The court found that OPTO failed to establish the existence of a trade secret because the information OPTO sought to protect was not shown to be generally known or readily ascertainable by proper means.

Statutory References
| 18 U.S.C. § 1839(3) | Definition of Trade Secret — This statute defines a trade secret as information that the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known or readily ascertainable. OPTO failed to meet this definition. |
| 18 U.S.C. § 1839(5) | Definition of Misappropriation — This statute defines misappropriation to include the acquisition, disclosure, or use of a trade secret by improper means. OPTO did not show that Honeywell acquired the information through improper means. |
Key Legal Definitions
Rule Statements

Know Your Rights
Real-world scenarios derived from this court's ruling:
Scenario: You are a software developer who created a unique algorithm for optimizing ad placement. You suspect a competitor has used a very similar algorithm after hiring one of your former employees.
Your Rights: You have the right to protect your trade secrets under the DTSA if you can prove the algorithm is a trade secret (not generally known or readily ascertainable by proper means) and that the competitor acquired or used it improperly.
What To Do: Gather evidence of your algorithm's uniqueness, the steps you took to keep it secret (e.g., NDAs, limited access), and any proof of the competitor's improper acquisition or use. Consult with an attorney specializing in trade secret law to assess your case.
Scenario: Your company developed a proprietary manufacturing process. You discover a former supplier is now selling products using a process that appears identical to yours.
Your Rights: You have the right to pursue a trade secret misappropriation claim if you can demonstrate your process meets the definition of a trade secret and the supplier obtained or used it improperly, potentially through breach of a confidentiality agreement or other wrongful means.
What To Do: Document your process, evidence of its secrecy (e.g., internal controls, limited disclosures), and the supplier's actions. Seek legal counsel to understand your options for enforcing your trade secret rights.
Is It Legal?
Common legal questions answered by this ruling:
Is it legal to use information that a former employee brings to your company?
Depends. If the information is a publicly available trade secret or the employee is free to use it, it may be legal. However, if the information is a protected trade secret and the employee is bound by confidentiality agreements, or if you acquire it through improper means, it is likely illegal and constitutes misappropriation.
This applies under federal law (DTSA) and state laws governing trade secrets.
Practical Implications
For Businesses seeking to protect proprietary information
This ruling reinforces the need for businesses to actively demonstrate that their information is not generally known or readily ascertainable by proper means and that they have taken reasonable steps to maintain its secrecy. Simply claiming information is secret is insufficient; proof is required.
For Companies accused of trade secret misappropriation
This case suggests that if the plaintiff cannot meet their initial burden of proving the existence of a trade secret and improper acquisition, summary judgment may be granted, potentially avoiding a lengthy trial.

Q: What did OPTO Electronics need to prove to win its trade secret case against Honeywell?

Q: Why did the Fourth Circuit rule in favor of Honeywell?
The Fourth Circuit affirmed summary judgment for Honeywell because OPTO failed to provide sufficient evidence that its information met the definition of a trade secret and that Honeywell obtained it improperly.
Q: What does 'generally known or readily ascertainable' mean in trade secret law?
It means the information is publicly available or can be easily figured out through legitimate methods, so it doesn't qualify for trade secret protection.
Q: What are 'improper means' of acquiring information?
Improper means include illegal or wrongful actions like theft, bribery, or misrepresentation to obtain information.
Q: What is the burden of proof in a trade secret misappropriation case?
The plaintiff, in this case OPTO, bears the burden of proving all elements of its trade secret claim, including the existence of a trade secret and its misappropriation.

Businesses can protect trade secrets through measures like non-disclosure agreements (NDAs), limiting access to sensitive information, using passwords and encryption, and marking documents as confidential.
Q: Does this ruling mean OPTO can never sue Honeywell again?
This ruling specifically addresses the trade secret misappropriation claim based on the evidence presented at the summary judgment stage. OPTO might have other claims or could potentially refile if they discover new evidence meeting the DTSA requirements, but this specific claim was resolved.
Q: What kind of evidence is needed to show information is 'not readily ascertainable'?
