Intellectual Property

Offering both advisory and litigation services, Lazareff Le Bars has developed a highly regarded intellectual property practice, particularly in the area of patents.

Our areas of expertise include mechanical engineering, electronics, information technology, biotechnology – pharmaceuticals and parapharmaceuticals, medical equipment and procedures, food products, chemistry and cosmetics. In this respect, we rely on the assistance from several patent engineers.

As advisors, we assist clients in deploying best practices with regard to patent and trademark registrations, managing IP portfolios and anticipating issues related to international expansion, in order to guard against the depreciation of their intangible assets or malevolent intentions of potential competitors. We provide advice that is tailored to the environments in which companies are evolving in today, particularly in respect to new export markets, and ensure that their rights are rigorously protected at all times.

In the event of a dispute or situation of crisis, we represent clients before courts of law, particularly the Paris Court of First Instance and Court of Appeals, state agencies and intergovernmental organizations such as INPI, USPTO, WIPO, AIPO, ARIPO, EPO and OHIM, as well as arbitral tribunals (particularly the ICC).
