Intellectual Property Rights, Média & Technology Law

Everything starts with an idea, but to be exploitable it must be strategically shaped (process, invention, work, know-how, design, etc.) and, if necessary, intelligently protected (confidentiality agreement, co-ownership, deposit, etc.).

At each stage of your project, the lawyers at CIRCLE Law will help you protect (anteriorities, filing, registration) and exploit (license, assignment, distribution) your innovations and creations, whatever their form: software, patentable or non-patentable invention, design, graphics, musical, cinematographic, live performance, creation in the field of fashion, luxury goods, or even web and video game development.
