Contractual obligation to third parties under Art. 393 § 2 k.c. terminates upon contract dissolution unless extended.

The Supreme Court dismissed the appeal against a judgment ordering patent licensees to pay royalties to co-creators after the patent expired and the license contract was terminated. The court found that the contractual reservation of payment obligations to third parties under Article 393 § 2 of the Civil Code ceases to exist upon the effective dissolution of the main agreement, absent a specific extension clause. Since the licensees failed to prove an agreement extending these obligations beyond the contract's end, the court ruled that the statutory rule governs the termination of such reservations.
