The use of export restrictions enables the licensor to regulate the competitive impact of the licensee's activities upon his own interests in other markets. The different types of export restrictions vary in intensity and can be used individually or in combination with one another. The most restrictive is the global export prohibition. In such cases, the economic activity of the licensee is limited to his domestic market; and frequently the licensee is also prohibited from selling the products covered by the licence to any third party who would export them. The requirement that the licensee obtain the licensor's prior approval to export is less restrictive, in that the possibility of exporting is not ruled out; but the licensor retains control over exports, and reserves the option of a global ban. As an alternative, approval for exports to specified countries may be provided for in the licence agreement. The extent of the restrictive nature of this provision will depend largely on the relative bargaining powers of the licensor, the licensee, and the government of the licensee's country.
Not all export restrictions are territorial constraints. A licensor can place a ceiling on the licensee's exports by means of an export quota, expressed in physical or monetary terms. This can either be coupled with a territorial limitation or used by itself. In the latter case, the competitive impact of the licensee's export activity is limited rather than directed. In addition, a licensor can use, singly or in connection with some form of territorial constraint, a provision restricting exports to specified products or specified product forms, and a provision prohibiting the exportation of products that are similar to, or substitutes for, the licensed goods. The latter restriction is frequently related to prohibition of the use of a trademark in export sales. Finally, the licensor can attempt to use the licence contract for the purpose of retaining control over the export (as well as of the domestic) price of the licensed product.
Other potential restrictive provisions deal with the tying of purchases of essential inputs to the licensor; restrictions on production patterns; payments of a minimum royalty; restrictions on the use of the acquired technology after the termination of the contract; restrictions on disclosure of the technology used; agreements not to challenge the validity of patents and trademarks transferred; and the mutual exchange, or unilateral grant-back, of technical improvements.
