The European Commission in their recent communication paper (COM (2017) 712 final)(EC paper) titled ‘Setting out the EU approach to Standard Essential Patents’ considered the obligations that are cast upon parties during pre-licensing negotiations of SEPs on FRAND terms. The EC paper has derived such obligations from the behavioral criteria as determined by the CJEU in the Huawei judgement. While Huawei provided the general framework, it further evolved through various court decisions in Germany and in the Unwired Planet case. This chapter reflects on the framework developed in the Huawei judgment and shows how this framework has evolved in the post Huawei cases in Germany and UK. The post Huawei cases have tried to adhere to the overall framework provided under Huawei, although there are number of inconsistencies as to specific obligations. From the perceived inconsistences, this chapter concludes on a note that the overall conduct of the parties would play a major role before granting injunctive relief to SEP holders.
