Daniels Health Sciences, L.L.C. v. Vascular Health Sciences, L.L.C.
710 F.3d 579
5th Cir.2013Background
- DHS sued VHS for misappropriation of trade secrets, breach of CNDA, and trademark violations related to Provasca and Arterosil.
- DHS and VHS formed DHS to research Provasca and VHS to market it; later VHS began Arterosil after severing ties.
- Daniels created The Path to Provasca and required confidentiality; CNDA signed by VHS prior to presentations.
- DHS alleged VHS used confidential information to develop and market Arterosil, violating CNDA and misappropriating trade secrets.
- District court granted TRO and then a preliminary injunction after findings of likelihood of success and irreparable harm.
- This court stayed the injunction pending appeal, then affirmed in part, remanding to narrow scope and expedite trial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Likelihood of success on the merits | DHS showed breach and misappropriation through the CNDA and compilation as trade secret. | The confidential information wasn't properly identified and remedies were overstated. | District court findings supported likelihood of success. |
| Irreparable harm | Harm includes reputational damage and jeopardized funding for Provasca. | Harm was speculative and damages could be redressed at law. | Irreparable harm likely established. |
| Balance of hardships | VHS’s damages are compensable; public interest favors DHS’s development. | VHS invested in Arterosil; injunction harms VHS. | Public and private interests weighed in DHS’s favor; injunction maintained. |
| Public interest | Protecting scientific progress and confidentiality benefits the public. | Restrains beneficial product development and profits. | Public interest favored DHS to protect confidential information and potential breakthroughs. |
| Scope of the preliminary injunction | injunction should cover misuse of confidential information and related product actions. | Overbreadth risks barring public-domain materials and unrelated products. | Remand to narrow scope; clarify terms to avoid overbreadth. |
