JUVE Patent

Szleper Henry – France 2020

JUVE Comment

This small IP boutique is well positioned in the French patent litigation market and primarily advises and litigates for clients from the pharma, mechanics and electronics sectors in patent disputes. The team is praised by clients and competitors alike, especially for its “efficiency and high skill”. In addition to national work, activity focuses on advice to German clients in patent disputes in France. Like Cousin & Associés, Szleper Henry nurtures long-standing contacts in Germany, including some notable companies. For Herrenknecht, a German manufacturer of tunneling technology, it won a first-instance victory against French-Chinese competitor NFM/Creusot. With its broad setup the firm is well set for smaller proceedings. Although a client praised the firm for its work in a life sciences nullity suit, the small team lacks the size needed for large, complex pharma or mobile communications disputes. But non-litigation advice is accounting for more work: examples include contractual issues in technology transfers of public research institutes looking to partner with industry, or patents advice in M&A deals.
