Hiroshi J. Sheraton

Baker & McKenzie LLP


Hiroshi Sheraton's practice covers all aspects of intellectual property law with a particular emphasis on contentious patent and trade mark matters and life sciences. Much of his work is cross-border in nature. He regularly co-ordinates pan-European and global IP litigation and advises clients on international IP strategies for patent litigation and brand protection. He represents clients in the UKIPO, EPO, OHIM, the English Courts and the CJEU. He has experience of IP matters across Europe and has litigated IP cases in Germany, France, Spain, Italy, the Netherlands, Belgium, Austria, Ireland, Northern Ireland and Luxembourg, the USA and Asia Pacific.

Although he has a first degree in biochemistry and molecular biology, he covers all areas of technology from pharmaceuticals/biotech products and agrochemicals to electronics and software.

Practice Focus

Hiroshi is particularly involved at the interface between IP law and other legal disciplines such as EU competition law. He is currently involved in one of the first "reverse payment" patent settlement cases pending before the European Commission, and has been involved in some of the leading cases concerning "Euro-defences" to IP infringement and abusive assertion of IP rights. He also has experience advising on pharmaceutical regulatory issues where they interact with traditional IP rights such as matters concerning Supplementary Protection Certificates, data exclusivity and clinical trials. In the brand protection arena, Hiroshi assists several household name brands on enforcement and portfolio management issues especially in highly regulated industries such as alcohol beverages and online gaming.
