The English-language edition of the commentary on the EU Portability Regulation (2017/1128) has just been published. Co-author is Dr. Sebastian Engels, attorney at BOEHMERT & BOEHMERT. He already contributed to the German-language commentary for the 12th edition 2018 of the renowned Fromm/Nordemann Copyright Commentary.
The freely accessibly online magazine Journal of Intellectual Property, Information Technology and E-Commerce Law (JIPITEC) has now published the English-language commentary. Like every article in the JIPITEC, this is also freely accessible.
