What Kilian, Kilian & Partner mbB does

Kilian · Kilian & Partner mbB is a Munich-based German patent law partnership (Partnerschaft mbB) founded circa 1994, operating continuously for approximately 30 years and specializing exclusively in intellectual property and industrial property protection. The firm employs five patent attorneys plus administrative support staff, with all attorneys holding dual qualifications as German Patent Attorneys and European Patent Attorneys/European Trademark and Design Attorneys admitted before the DPMA, EPO, EUIPO, WIPO, and the Unified Patent Court (UPC). Managing Partners Marco Müller-Gürtner (since 2003) and Christoph Kilian (since 2005) lead the practice alongside Dr. Marion Scharping, Dieter H. Konnerth, and Matthias Fischer (of counsel since end-2023).

The firm's core offering covers the full IP lifecycle: preparation and prosecution of patent, utility model, trademark, and design applications; opposition, nullity, and cancellation proceedings; infringement actions including preliminary injunctions; freedom-to-operate analyses; state-of-the-art and competitor-litigation searches; patent, trademark, and design monitoring; and worldwide annuity and renewal administration. Adjacent practice areas include employee invention law (including establishing internal invention management systems for corporate clients), competition law, internet law (domain disputes), and customs enforcement (border seizure and destruction proceedings). Technical coverage is unusually broad for a five-attorney firm, spanning mechanical engineering, electrical engineering, microelectronics/semiconductor, sensorics, image processing, medical technology, optics, printing, analytics, automotive, e-mobility, and plant engineering.

The business model is fee-for-service professional services, with revenue generated from per-matter and hourly engagements; pricing is not publicly disclosed. GTM is direct relationship-based, serving both German and international clients with multilingual support in German, English, and Japanese. Digital infrastructure consists of a secure Document Exchange Server and the eKKP Patent Renewal System client portal, which support operational efficiency but are not commercial products. Ownership is concentrated among the managing partners with no external investors, and the firm has no subsidiaries, partnerships, or acquisition history.
