THE EMPLOYEE expressly acknowledges that pursuant to Article 163 of the Mexican Labor Law, all rights to any inventions, improvements and any intellectual property rights (“Intellectual/Industrial Property Rights”), made, written, designed, developed or produced by THE EMPLOYEE for the duration of this contract, is property of THE EMPLOYER and must be assigned to the latter. THE EMPLOYER will have the right to freely develop and alter such Intellectual/Industrial Property Rights and to license and assign them to third parties. THE EMPLOYEE agrees to promptly disclose any invention, improvement or intellectual property during the course of employment and undertakes without any additional compensation to execute all such deeds and documents that, at THE EMPLOYER’s sole discretion, are necessary or desirable in order for THE EMPLOYER being able to protect, register, maintain and in any other way be able to fully enjoy its right of intellectual property referred to under this section. THE EMPLOYEE must notify THE EMPLOYER in writing with respect to any invention, improvement or intellectual property conceived before the signing date of this contract. Absence of such notice will result in any invention, improvement or intellectual property devised by THE EMPLOYEE to be subject to the obligations above.
This clause looks incredibly suspicious to me wrt the potential for abuse, especially the last sentence. Or is my interpretation wrong and this clause doesn't mean that the company can seize any IP that I "conceived" before employment and didn't notify the employer about?
If this is the actual meaning, can such a clause be actually enforced or it has no legal power?
