SEPs licensing across the supply chain: an antitrust perspective

The rise of the Internet of Things (IoT) and the development of 5G are set to add a new layer of complexity to the current practice of standard essential patents (SEPs) licensing. While, until recently, the debate has centred on the nature of fair, reasonable and non-discriminatory (FRAND) commitments and the mechanisms to avoid hold-up and reverse hold-up problems between licensors and licensees, a new hotly-debated issue has now emerged. At its core is the question of whether SEP holders should be required to grant a FRAND licence to any implementer seeking a licence, including component makers (the so-called ‘licence-to-all’ approach), or if they should be allowed freely to target the supply-chain level at which the licence is to be granted (the so-called ‘access-for-all’ approach). After providing an up-to-date overview of the current legal and economic debate, this article focuses on the most recent antitrust case law dealing with the matter on both sides of the Atlantic and argues that no sound economic and legal bases which favour licence-to-all solutions can be identified. * The authors would like to thank the anonymous referees, Luigi Federico Signorini and the participants in the 2021 Annual Conference of European Policy for Intellectual Property (EPIP), in the 38th Annual Conference of the European Law and Economics Association (EALE), in the TILTing Perspectives 2021 (Tilburg University), and in the 16th Annual Conference of the Academic Society for Competition Law (ASCOLA).

The first is Half-Causation Branching, which allows the logical mapping of the inventing space, within which the imaginary invention is located. Implementing this tool reveals two alternative nearby inventions, which if left out of the sought patent protection would render any eventually granted patent practically worthless. Following that, Half-Causation Encapsulation comes to the rescue by allowing the encapsulation of the original imaginary invention, plus the two alternative nearby ones, all in a manner that provides the all-important unity of invention On the one hand, patent agents are not supposed to contribute to their client’s inventive concept to the extent that they become co-inventors. On the other hand, scientists and engineers are not supposed to dedicate so much time and effort to learning about complex patent laws as to become patent agents. Arguably, each should aim to excel in their discipline. However, a structured dialogue should be considerably helpful to each and to the patent process as a whole. It is proposed that Half-Causation, with its logical structure, can provide a basis for such a dialogue. Besides targeting a readership in patent practices and theory, this paper should be of interest to multiple readerships, for example in engineering design, medical discovery and philosophy of technology.
