The Ipsilon Story: Growth Driven by Innovation, Excellence, and Strategic Acquisitions

Ipsilon was founded by Valérie Feray in 2000 in France. Under her leadership, the company has achieved remarkable growth over the past two decades, capitalising on both organic growth — notably through the opening of regional and international offices in Germany and the United States — and external growth by integrating several firms in France and the Benelux.

Ipsilon’s strength lies in its DNA, defined by excellence, proximity, and commitment. Customers and employees are always at the heart of the group’s focus, which has enabled it to be recognised as a leading firm in benchmark rankings.

A major turning point came in 2022 with the investment from Waterland Private Equity. Since then, Ipsilon has made several strategic acquisitions that have significantly expanded its portfolio of services and reinforced its ambition to become a major player in intellectual property both in Europe and worldwide.

Ipsilon is selective about the companies it integrates, ensuring they share its entrepreneurial DNA — characterised by operational flexibility and responsiveness — without ever compromising on excellence.

The company offers a wide range of services covering all areas of industrial and intellectual property, from patent and trade mark drafting to litigation. Present in France, the Benelux, Germany, the United States, and China, the group employs around 450 people.

Today, Ipsilon is the largest IP firm in the EU, the market leader in the Benelux, and one of the top three IP consultancies in France. It enjoys a leading position in major industry rankings such as the Financial Times, Juve Patent, and Décideurs Magazine, thanks to its expertise across all technical fields.

Under the continued leadership of Valérie Feray, Ipsilon is expanding its international footprint while remaining true to the core values that have driven its success since its inception.

“With a partner like Waterland, we have been able to look to the future in an ambitious way. In just two years, our partnership has almost tripled the size of our company.” – Valérie Feray
