Washington Appeals Court Reinstates Trade Secrets Lawsuit Against Former Podiatry Employee
A legal battle over patient data in the Seattle area has taken a significant turn after a Washington state appeals court decided to revive a lawsuit involving two podiatry practices. The case centers on allegations that a former employee stole proprietary patient information to benefit his own new business.
The Core of the Dispute: Patient Data and Trade Secrets
The legal conflict involves Mill Creek Foot & Ankle Clinic and its owner, Dr. Joseph Hall, who brought claims against a former employee, Nathan Hansen. According to court documents, the dispute arose after Hansen left the clinic to establish his own practice, Hansen Foot & Ankle LLC.
Dr. Hall alleges that Hansen stole patient data from the clinic to help build his separate practice. This led to claims regarding the misappropriation of trade secrets and breaches of contract. In the medical field, patient lists and contact data are often viewed as protected trade secrets because they represent years of business development and professional relationships.
The Appeals Court Decision
After an initial phase of litigation, the case was recently reinstated by the Washington Court of Appeals. The court’s decision allows the trade secrets and contract claims brought by Mill Creek Foot & Ankle Clinic and Dr. Hall to proceed against Hansen. This ruling effectively revives the litigation, meaning the allegations of data theft will now be addressed more fully in court.
The reinstatement of these claims highlights the legal protections available to medical practices when former staff members are accused of using internal data to compete unfairly in the same local market.
Key Takeaways of the Case
- Parties Involved: Mill Creek Foot & Ankle Clinic (Dr. Joseph Hall) vs. Nathan Hansen and Hansen Foot & Ankle LLC.
- Primary Allegation: The theft of patient data for the purpose of starting a competing podiatry practice.
- Legal Status: The Washington Court of Appeals has reinstated the trade secrets and contract claims on appeal.
Why This Matters for Medical Practices
This case serves as a reminder of the importance of clear employment contracts and data security protocols within healthcare settings. When a provider transitions from an employee to a competitor, the ownership of patient records and the use of “trade secrets” often become flashpoints for litigation.

For practice owners, this ruling underscores the potential for legal recourse when patient data is allegedly misappropriated. For employees, it emphasizes the risks associated with taking proprietary information when departing a clinic.
Looking Ahead
With the case now revived, the legal proceedings will likely focus on the evidence regarding how the patient data was accessed and used. The outcome will depend on whether the court finds that the information stolen constitutes a protected trade secret and if a valid contract was breached during Nathan Hansen’s departure from Mill Creek Foot & Ankle Clinic.
