Bronze - Firms: litigation

For a holistic, solutions-oriented service at every stage of the patent lifecycle, CASALONGA has it covered. Home to both patent attorneys and attorneys at law, the group provides commercially on-point advice that takes in the big picture from both a technical and legal standpoint – a formula that chimes with innovators of all stripes. Contentious firepower is supplied in abundance by Arnaud Casalonga, who has spent more than 25 years battling it out in cross-border patent disputes. While no industry is off limits, he has lately been carving a niche in the SPC space and maintains a thriving unfair competition practice to boot. Patent attorney Gérard Dossmann is also active on the contentious side, coordinating pan-European litigation campaigns and advocating in EPO opposition proceedings. Chemistry, pharmaceuticals and biotechnology all fall within his wheelhouse. For meticulous, forward-focused prosecution, look no further than Francis Zapalowicz, an electronics specialist who previously helped to design automatic control systems for aircraft; today, he advises on sweeping patent filing programmes, appears in opposition and appeal proceedings, and dispenses infringement advice.
