Law, Stephen, M.2023-06-072023-06-07https://unbscholar.lib.unb.ca/handle/1882/35160Hybrid licences tie trade secret rights (which have no fixed expiration) to related patent rights (which expire). Although level royalty hybrid licences, which charge a single royalty for both rights, have been prohibited, it can be shown that infinite-term licensing (ITL) for patent rights may be better than a limited-term patent, when returns to the licensor are fixed. This paper explains hybrid licensing as a means of privately implementing the efficient ITL outcome when returns to the licensor are constrained but not necessarily fixed, without requiring a change in the length of the patent term.Englishhttp://purl.org/coar/access_right/c_16ecsenior report
