Facts

Plaintiff manufactured specialized valves and had long kept its manufacturing drawings and related technical information confidential. Whalen worked for plaintiff for many years as chief engineer and later vice-president, and his duties included developing, redesigning, and improving plaintiff's valves, solving field problems, and working with patent counsel to obtain protection and assign rights to plaintiff. The trial court found that it was an implied condition of his employment that improvements, modifications, related designs, and patent rights developed during employment belonged to plaintiff, including work done at home and outside regular hours. While still employed and using information and problems reported to him in confidence, Whalen designed improved valves, concealed them from plaintiff, organized a competing corporation, and quickly marketed the redesigned valves to plaintiff's market after leaving.

Issue

May an employee hired to use his inventive skill to improve his employer's products conceal and appropriate those improvements for his own competing business? Also, may a corporate officer use confidential information and his position to prepare and launch a competing enterprise that injures the corporation?

Rule

Where a person is employed to design improvements to the product of his employer, or to design new products for his employer, he may not use the results of that work for his own use and benefit, particularly to the detriment of the employer. An implied employment agreement may require disclosure, assignment, and nonuse of such improvements, and that obligation applies to work within the scope of employment even if done at home or outside regular hours. In addition, a corporate officer owes a fiduciary duty of undivided loyalty and may not use confidential information or his position to create a competing enterprise that cripples or injures the corporation.

Ridgeway Process Controls, a fictional manufacturer in Tulsa, hires Elena Park as its lead design engineer to redesign existing pressure regulators and solve recurring field failures reported by service technicians. Over several months, Elena develops a new regulator geometry at her apartment at night, keeps it secret, resigns, and begins selling the redesign through her own new company in the same market.

Who has the stronger claim to the redesign under the governing rule?

Explanation. When an employee is hired to design improvements to the employer's products or to devise solutions to product problems, the successful result of that work belongs to the employer if it falls within the scope of the employment. The majority opinion emphasizes that this remains true even if much of the physical work occurs at home or outside regular hours. Patent status is not the source of the employer's right where the parties' employment relationship implies disclosure and assignment obligations.
