Lorenz Seidler Gossel

What Lorenz Seidler Gossel does

Lorenz Seidler Gossel is a Munich-based IP boutique law firm operating as a Partnerschaft mbB (German partnership form), founded in 1962. The firm specializes in trademark, patent, copyright, design, and competition/unfair competition law, with a combined bench of attorneys-at-law and patent attorneys — a configuration relatively rare in Germany. It serves three stated client segments: international corporations, German mid-sized companies, and start-ups, with publicly named clients including adidas, Casio Europe, Telefónica, ProSiebenSat.1, Ford, Gabor Shoes, Julius Blum, Salamander, and Fresenius Medical Care.

The firm operates from a single Munich office with approximately 12 equity partners and a broader professional team of roughly two dozen attorneys/patent attorneys supported by administrative staff. Its service offering spans IP prosecution (trademark and patent filings, design registration), IP litigation (including before the Unified Patent Court following the 2023 unitary patent regime), IP portfolio advisory, licensing, and unfair competition matters. Revenue mechanics follow the standard professional-services model: hourly fees, retainers, and success-based fees depending on matter type. The firm has no external shareholders, parent company, or funding — it is wholly partner-owned — and there is no indication of external investment.

Strategically, the firm has executed a measured expansion over 2022–2024, including the addition of multiple counsels and associates, the 2024 admission of Xiaodi Wang (a Chinese-qualified patent attorney) as partner, the launch of a Chinese-language website targeting inbound Chinese applicants, and the build-out of a Unitary Patent / UPC practice. These moves indicate deliberate widening of geographic reach (China inbound) and product surface (pan-European patent enforcement) while preserving the single-office boutique structure. The firm maintains consistent placement across major legal directories — Chambers, Legal 500, JUVE, WTR 1000, IAM Patent 1000, and MIP IP Stars.
