Article 10A. 
Inventions Developed by Employee. 
§ 66‑57.1.  Employee's right to certain inventions.
Any provision in an employment agreement which provides that the employee shall assign or offer to assign any of his rights in an invention to his employer shall not apply to an invention that the  employee developed entirely on his own time without using the employer's equipment, supplies, facility or trade secret information except for those inventions that (i) relate to the employer's business or actual or demonstrably anticipated research or development, or (ii) result from any work performed by the employee for the employer. To the extent a provision in an employment agreement purports to apply to the type of invention described, it is against the public policy of this State and is unenforceable. The employee shall bear the burden of proof in establishing that his invention qualifies under this section. (1981, c. 488, s. 1.)

§ 66‑57.2.  Employer's rights.
(a)	An employer may not require a provision of an employment agreement made unenforceable under G.S. 66‑57.1 as a condition of employment or continued employment. An employer, in an employment agreement, may require that the employee report all inventions developed by the employee, solely or jointly, during the term of his employment to the employer, including those asserted by the employee as nonassignable, for the purpose of determining employee or employer rights.
(b)	An employer's ownership of an employee's invention, discovery, or development that has or becomes vested in the employer by contract or by operation of law shall not be subject to revocation or rescission in the event of a dispute between the employer and employee concerning payment of compensation or benefits to the employee, subject to any contrary provision in the employee's written employment agreement. The foregoing provision shall not apply where the employee proves that the employer acquired ownership of the employee's invention, discovery, or development fraudulently.
(c)	If required by a contract between the employer and the United States or its agencies, the employer may require that full title to certain patents and inventions be in the United States.  (1981, c. 488, s. 1; 2016‑114, s. 4.)
