Life Spine, Inc. v. Aegis Spine, Inc., No. 21-1649 (7th Cir. 2021)
Annotate this Case
Life Spine makes and sells a spinal implant device called the ProLift Expandable Spacer System. Aegis contracted with Life Spine to distribute the ProLift to hospitals and surgeons. Aegis promised to protect Life Spine’s confidential information, act as a fiduciary for Life Spine’s property, and refrain from reverse-engineering the ProLift. Aegis nonetheless funneled information about the ProLift to its parent company, L&K Biomed to help L&K develop a competing spinal implant device. Shortly after L&K’s competing product hit the market, Life Spine sued Aegis for trade secret misappropriation and breach of the distribution agreement. The district court granted Life Spine a preliminary injunction barring Aegis and its business partners from marketing the competing product. Aegis argues that the injunction rested on a flawed legal conclusion—that a company can have trade secret protection in a device that it publicly discloses through patents, displays, and sales.
The Seventh Circuit affirmed. While public domain information cannot be a trade secret, a limited disclosure does not destroy all trade secret protection. Life Spine did not publicly disclose the specific information that it seeks to protect by patenting, displaying, and selling the ProLift. Life Spine’s trade secrets are not in the public domain but are accessible only to third parties who sign confidentiality agreements.
