We are a close-knit team of attorneys and professionals with a strong passion for intellectual property as well as a longstanding experience in this field. We are driven by a commitment to provide our clients with the highest quality of service to best protect and enhance the value of their intellectual property assets.

Previously known as Siblegal, our group has chosen a new name and image to better communicate our vision and corporate identity.

It is our belief that solutions must be tailor-made for each client’s needs and that various areas of expertise and a variety of approaches are key to determining the best legal strategies. For this reason, we specialize in all areas of intellectual property, and work with equal dedication and expertise in civil, criminal, administrative, customs, extrajudicial and contractual ambits.

Our approach to all cases is global and interdisciplinary. When called for, we use unconventional and creative solutions, sometimes pursuing new avenues in intellectual property.

Though it is our job to analyze all aspects of a case, we believe that our advice to clients must always be clear and to the point. We strive to work pragmatically and cost-effectively while never losing our broader vision.

We know that every client has unique business needs and objectives. To best serve our clients, we need to think as they do and never stop learning from them. Understanding each client’s history, day-to-day activity and vision for the future is essential to promoting and protecting its interests and priorities.

We privilege simplicity and clarity.

Our reach is international to fully support our clients in meeting the challenges of the global marketplace.

At Spheriens we provide legal assistance in all areas of intellectual property law as well as in all fields relevant to the protection of intangible assets, with a particular focus on fashion and luxury goods.
