(a) General rule. Section 1235 provides that a transfer (other than by gift, inheritance, or devise) of all substantial rights to a patent, or of an undivided interest in all such rights to a patent, by a holder to a person other than a related person constitutes the sale or exchange of a capital asset held for more than 1 year (6 months for taxable years beginning before 1977; 9 months for taxable years beginning in 1977), whether or not payments therefor are:
(1) Payable periodically over a period generally coterminous with the transferee's use of the patent, or
(2) Contingent on the productivity, use, or disposition of the property transferred.
(b) Scope of section 1235. If a transfer is not one described in paragraph (a) of this section, section 1235 shall be disregarded in determining whether or not such transfer is the sale or exchange of a capital asset. For example, a transfer by a person other than a holder or a transfer by a holder to a related person is not governed by section 1235. The tax consequences of such transfers shall be determined under other provisions of the internal revenue laws.
(c) Special rules--(1) Payments for infringement. If section 1235 applies to the transfer of all substantial rights to a patent (or an undivided interest therein), amounts received in settlement of, or as the award of damages in, a suit for compensatory damages for infringement of the patent shall be considered payments attributable to a transfer to which section 1235 applies to the extent that such amounts relate to the interest transferred. For taxable years beginning before January 1, 1964, see section 1304, as in effect before such date, and Sec. 1.1304A-1 for treatment of compensatory damages for patent infringement.
(1) Payments for infringement. If section 1235 applies to the transfer of all substantial rights to a patent (or an undivided interest therein), amounts received in settlement of, or as the award of damages in, a suit for compensatory damages for infringement of the patent shall be considered payments attributable to a transfer to which section 1235 applies to the extent that such amounts relate to the interest transferred. For taxable years beginning before January 1, 1964, see section 1304, as in effect before such date, and Sec. 1.1304A-1 for treatment of compensatory damages for patent infringement.
(2) Payments to an employee. Payments received by an employee as compensation for services rendered as an employee under an employment contract requiring the employee to transfer to the employer the rights to any invention by such employee are not attributable to a transfer to which section 1235 applies. However, whether payments received by an employee from his employer (under an employment contract or otherwise) are attributable to the transfer by the employee of all substantial rights to a patent (or an undivided interest therein) or are compensation for services rendered the employer by the employee is a question of fact. In determining which is the case, consideration shall be given not only to all the facts and circumstances of the employment relationship but also to whether the amount of such payments depends upon the production, sale, or use by, or the value to, the employer of the patent rights transferred by the employee. If it is determined that payments are attributable to the transfer of patent rights, and all other requirements under section 1235 are met, such payments shall be treated as proceeds derived from the sale of a patent.
(3) Successive transfers. The applicability of section 1235 to transfers of undivided interest in patents, or to successive transfers of such rights, shall be determined separately with respect to each transfer. For example, X, who is a holder, and Y, who is not a holder, transfer their respective two-thirds and one-third undivided interests in a patent to Z. Assume the transfer by X qualifies under section 1235 and that X in a later transfer acquires all the rights with respect to Y's interest, including the rights to payments from Z. One-third of all the payments thereafter received by X from Z are not attributable to a transfer to which section 1235 applies.
(d) Payor's treatment of payments in a transfer under section 1235. Payments made by the transferee of patent rights pursuant to a transfer satisfying the requirements of section 1235 are payments of the purchase price for the patent rights and are not the payment of royalties.
(e) Effective date. Amounts received or accrued, and payments made or accrued, during any taxable year beginning after December 31, 1953 and ending after August 16, 1954, pursuant to a transfer satisfying the requirements of section 1235, whether such transfer occurred in a taxable year to which the Internal Revenue Code of 1954 applies, or in a year prior thereto, are subject to the provisions of section 1235.
(f) Nonresident aliens. For the special rule relating to nonresident aliens who have gains arising from a transfer to which section 1235 applies, see section 871 and the regulations thereunder. For withholding of tax from income of nonresident aliens, see section 1441 and the regulations thereunder.
