Wallinger Ricker Schlotter Tostmann was founded in 2007 following the merger of the leading automotive and mechanical engineering IP firm Wallinger and Partners, founded by Michael Wallinger in 1989, and the chemistry/pharmaceutical IP practice group of an international US-based law firm, led by Mathias Ricker – the firm’s European IP coordinator and co-founder of the Munich IP group.

Since 2007 Wallinger Ricker Schlotter Tostmann has continued to expand and now includes more than 25 lawyers and technical experts. The firm relies on experienced patent attorneys and attorneys at law to serve its clients, most of whom have significant IP experience, while many also have a strong industry background, having worked in R&D and management positions before joining Wallinger Ricker Schlotter Tostmann.

While some of these attorneys joined from different law firms, Wallinger Ricker Schlotter Tostmann has also established a successful patent attorney trainee programme that consistently adds home-grown talent to the team.
