Leinen Derichs

What Leinen Derichs does

Leinen & Derichs Anwaltskanzlei is a German law firm partnership (Partnerschaft) headquartered in Cologne, operating under the legal name "Leinen & Derichs Anwaltskanzlei" with more than 80 years of continuous practice. As of the latest data, the firm employs 6 people, anchored by two named partners: Lothar Schmude (partner since 1980, specializing in health and medical law, including physician contract law, medical malpractice, and hospital law) and Dr. Walter Müller (partner since 1991, specializing in construction and architectural law and holding the Fachanwalt für Bau- und Architektenrecht designation since 2010). The firm's service offering is organized around two horizontal practice areas: Bau & Immobilien (Construction & Real Estate), covering public planning law, property law, architect/engineer law, broker law, and private construction law; and Gesundheit & Recht (Health & Law), covering medical law, hospital law, ambulatory care structures, medical products law, pharmaceutical law, and nursing law.

The underlying technology stack is minimal and consistent with a traditional German boutique: an informational website using SSL encryption and basic web analytics (Google Analytics, Matomo), with no proprietary software products, no APIs or SDKs, and no AI/ML capabilities. Service delivery relies on direct attorney-led advisory, contract drafting, legal project management, and litigation representation, with interdisciplinary cooperation with auditors and non-legal specialists where matters require it.

The business model is professional-services based. Revenue is generated primarily through legal fees governed by the Rechtsanwaltsvergütungsgesetz (RVG, the German Legal Fee Act), with the option to negotiate individual fee agreements for specialized or complex matters. Pricing is not publicly disclosed. Distribution is entirely direct: clients engage the firm through phone, email, or website contact at the Cologne office, and the firm claims to serve clients both nationwide across Germany and internationally from this single location. Customer acquisition leans on professional network memberships, referrals, and association-driven visibility rather than paid advertising, and the firm holds a founding membership (since 2003) in Netzwerk Bauanwälte, a nationwide network of construction law specialists.
