Subsequent to the publication of the 12th edition of the standard work “Gross/Strunk, The License Agreement (Der Lizenzvertrag)” in 2020, Michael Gross now published the 5th edition of the standard work "Gross/Strunk , Lizenzgebühren (Royalty Rates)”. Together with the 3rd edition of the standard work “Gross, IP-IT-Mediation” these books are the indispensible basis for a realistic setup to draft and negotiate license agreements and for successful negotiations in patent infringement proceedings.
