444 S.W.3d 251
Tex. App.2014Background
- Halliburton develops wellbore plugs; Wilkinson was a Halliburton technician (1998–2008) with access to confidential engineering, test, and vendor information and signed a patent/employment agreement assigning inventions and materials to Halliburton.
- While still employed and shortly after leaving, Wilkinson took Halliburton documents, used confidential information to design a competing plug for Axis, and Axis sold over 1,300 units generating substantial revenue and profit.
- Halliburton sued Wilkinson and Axis for trade-secret misappropriation, breach of contract, and breach of fiduciary duty; a jury found for Halliburton on all claims and awarded monetary damages to Halliburton.
- The trial court’s initial injunction prohibited use/disclosure of trade secrets but limited use restrictions to a finite period (first 10 months, later extended to 18 months) and did not declare Halliburton the owner of designs; it did order turnover of hard copies and some electronic materials.
- Halliburton appealed, arguing it was entitled to a perpetual injunction, a declaratory judgment of ownership of designs/documents created or made available to Wilkinson while employed, and an order requiring destruction of appellees’ electronic copies.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether injunction duration should be perpetual or limited | Halliburton: perpetual injunction required to remove unfair advantage from misappropriation | Axis/Wilkinson: limited "lead-time" injunction is sufficient; trade secrets are publicly ascertainable or reverse-engineerable | Court: reversed trial court; perpetual injunction required because defendants failed to prove limited duration would remove advantage |
| Whether injunction language was impermissibly vague | Halliburton: language ("to the extent that") allows defendants to decide scope; needs clarity to enjoin the proven product | Defendants: language appropriately narrows the injunction to what uses rely on Halliburton trade secrets | Court: modified injunction to remove ambiguous qualifier and unambiguously enjoin products proven to be based on Halliburton trade secrets |
| Whether declaratory judgment of ownership should be rendered | Halliburton: contract and evidence show designs/documents created or made available to Wilkinson are Halliburton's property; declaratory relief necessary to prevent future harm | Defendants: no jury finding that designs were "inventions"; declaratory relief unnecessary and may duplicate damages | Court: held Halliburton entitled to declaratory judgment of ownership under contract (no "invention" finding required) |
| Whether defendants must destroy electronic copies | Halliburton: destruction is necessary corollary to ownership declaration and turnover to prevent continued use | Defendants: this is additional injunctive relief requiring abuse-of-discretion review | Court: ordered destruction of electronic copies as necessary to effectuate exclusive ownership and prevent ongoing harm |
