Which factor is used to determine whether an employer has acquired a shop right?

• A. Whether the invention was created in the employee's free time.
• B. The existence of a patent assignment.
• C. Whether the employee consented to the employer's use of the invention.
• D. The employee's personal financial investment.

Answer: (C)

Shop rights are an implied permission that lets an employer continue using an invention created by an employee, typically when the invention arises in the course of employment or with the employer’s resources. The crucial factor is whether the employee consented to the employer’s use of the invention. That consent signals that the inventor and the employer have agreed—at least in effect—to allow the employer to practice the invention, which is exactly what a shop right licenses. In practice, other elements matter too—such as whether the invention was made using the employer’s facilities or time—but consent to the employer’s use serves as the clearest indicator that a shop right exists. If the employee did not consent to the employer’s use, the employer’s right to practice the invention is much less clear, even if the invention was created during employment.
