At licenstageren pålægges pligt til at meddele licensgiveren licens på de af ham tilførte forbedringer af den overførte knowhow og/eller de meddelte patenter, vil normalt heller ikke have nogen konkurrencebegrænsende virkning, forudsat at licenstageren i henhold til aftalen har adgang til licensgiverens fremtidige erfaringer og opfindelser.
Undertakings by the licensee to grant back to the licensor a licence for improvements to the licensed know-how and/or patents are generally not restrictive of competition if the licensee is entitled by the contract to share in future experience and inventions made by the licensor.
