This book provides a systematic overview of recent German case law on the fair, reasonable, and non-discriminatory (FRAND) licensing of standard-essential patents (SEP). Principal SEP/FRAND concepts are demonstrated and analysed, such as willingness to license, the FRAND offer, reaction duties and the counteroffer, FRAND-compliance of royalties, portfolio transfers, confidentiality disputes and damages. Global forward-looking topics are also considered in relation to German developments.
