# § 901. Definitions
**(a)** As used in this chapter—
**(1)** a “semiconductor chip product” is the final or intermediate form of any product—
**(A)** having two or more layers of metallic, insulating, or semiconductor material, deposited or otherwise placed on, or etched away or otherwise removed from, a piece of semiconductor material in accordance with a predetermined pattern; and
**(B)** intended to perform electronic circuitry functions;
**(2)** a “mask work” is a series of related images, however fixed or encoded—
**(A)** having or representing the predetermined, three-dimensional pattern of metallic, insulating, or semiconductor material present or removed from the layers of a semiconductor chip product; and
**(B)** in which series the relation of the images to one another is that each image has the pattern of the surface of one form of the semiconductor chip product;
**(3)** a mask work is “fixed” in a semiconductor chip product when its embodiment in the product is sufficiently permanent or stable to permit the mask work to be perceived or reproduced from the product for a period of more than transitory duration;
**(4)** to “distribute” means to sell, or to lease, bail, or otherwise transfer, or to offer to sell, lease, bail, or otherwise transfer;
**(5)** to “commercially exploit” a mask work is to distribute to the public for commercial purposes a semiconductor chip product embodying the mask work; except that such term includes an offer to sell or transfer a semiconductor chip product only when the offer is in writing and occurs after the mask work is fixed in the semiconductor chip product;
**(6)** the “owner” of a mask work is the person who created the mask work, the legal representative of that person if that person is deceased or under a legal incapacity, or a party to whom all the rights under this chapter of such person or representative are transferred in accordance with section 903(b); except that, in the case of a work made within the scope of a person’s employment, the owner is the employer for whom the person created the mask work or a party to whom all the rights under this chapter of the employer are transferred in accordance with section 903(b);
**(7)** an “innocent purchaser” is a person who purchases a semiconductor chip product in good faith and without having notice of protection with respect to the semiconductor chip product;
**(8)** having “notice of protection” means having actual knowledge that, or reasonable grounds to believe that, a mask work is protected under this chapter; and
**(9)** an “infringing semiconductor chip product” is a semiconductor chip product which is made, imported, or distributed in violation of the exclusive rights of the owner of a mask work under this chapter.
**(b)** For purposes of this chapter, the distribution or importation of a product incorporating a semiconductor chip product as a part thereof is a distribution or importation of that semiconductor chip product.
