Case Brief: E.I. DuPont deNemours & Co. v. Christopher
Court: United States Court of Appeals for the Fifth Circuit
Citation: 431 F.2d 1012 (5th Cir. 1970)
Decided: August 25, 1970
Facts:
E.I. DuPont deNemours & Co. (DuPont) was in the process of constructing a new methanol plant in Texas. During the construction, the defendants, John and William Christopher (the Christophers), hired a pilot to fly over the facility and take aerial photographs. DuPont sued, alleging that the Christophers wrongfully obtained trade secrets through aerial surveillance, constituting a misappropriation of trade secrets.
Issue:
The key issue was whether the act of aerial photography of DuPont's construction site constituted a wrongful appropriation of trade secrets under Texas law.
Holding:
The Fifth Circuit Court of Appeals held that the Christophers' actions did indeed constitute a wrongful appropriation of trade secrets, even though no physical trespass occurred.
Legal Reasoning:
- Misappropriation of Trade Secrets: The court emphasized that the acquisition of trade secrets through improper means is actionable under Texas law. The term "improper means" encompasses various methods that are not limited to illegal acts, but include activities deemed unethical or improper by societal standards.
- Reasonable Expectation of Privacy: DuPont had a reasonable expectation of privacy in its construction process and trade secrets, even though the site was open to view from the air. The court noted that it would be unreasonable to expect companies to cover their facilities from aerial observation.
- Balancing Interests: The court weighed the interests of protecting trade secrets against the public interest in allowing free access to information. It concluded that the protection of trade secrets justified restricting such means of obtaining information when they are deemed improper.
- Unfair Competition: The court reasoned that allowing competitors to use such surveillance techniques would promote unfair competition, undermining the incentive for innovation and investment in new technologies.
Conclusion:
The Fifth Circuit ruled in favor of DuPont, finding that the Christophers' use of aerial photography to obtain trade secrets constituted an improper means of appropriation. This decision underscored the principle that trade secrets should be protected from not only illegal but also unethical and improper methods of acquisition.
