N.Y. Labor Law § 203-f: Inventions made by employees

§ 203-f. Inventions made by employees. 1. Any provision in an

employment agreement which provides that an employee shall assign, or

offer to assign, any of his or her rights in an invention to his or her

employer shall not apply to an invention that the employee developed

entirely on his or her own time without using the employer's equipment,

supplies, facilities, or trade secret information except for those

inventions that either:

(a) relate at the time of conception or reduction to practice of the

invention to the employer's business, or actual or demonstrably

anticipated research or development of the employer; or

(b) result from any work performed by the employee for the employer.

2. To the extent a provision in an employment agreement purports to

require an employee to assign an invention otherwise excluded from being

required to be assigned under subdivision one of this section, such

provision is against the public policy of this state and shall be

unenforceable.
