WSL Patentanwälte Partnerschaft mbB

What WSL Patentanwälte Partnerschaft mbB does

WSL Patentanwälte Partnerschaft mbB is a German intellectual property law firm founded in 1949, headquartered in Wiesbaden with a second office opened in Munich in 2024. The firm is organised as a Partnerschaft mit beschränkter Berufshaftung (mbB) under the Partnerschaftsgesellschaftsgesetz and is led by ten partners. It provides patent prosecution and litigation, utility-model protection, trademark and design registration and enforcement, opposition and nullity proceedings, IP strategy and transactions, and employee-invention counselling, representing clients before the German Patent and Trademark Office, the European Patent Office, EUIPO, and the Unified Patent Court (UPC). Geographic reach claimed covers Europe, North America, Central and South America, Africa, and Asia through European opposition and nullity filings (up to 39 countries), African portfolio work (20+ countries), and direct application work in the Americas and Asia.

The firm differentiates on the basis of technical depth: partners hold doctoral degrees in disciplines spanning mechanics, electrical engineering, physics, inorganic and organic chemistry, polymer chemistry, biochemistry, biotechnology, pharmacy, medical technology, and software, supported by European Patent Attorney and European Patent Litigator credentials. In 2021, it merged with Mehler Achler Patentanwälte to expand capacity and technical breadth. Its marketing relies on the firm website, an educational "IP-Wissen" content section, and professional referral networks; customer-facing segments include corporate IP managers and counsel, individual inventors and start-ups, managing directors and senior executives, and investors performing IP due diligence.

The business model is fee-based professional services with revenue driven by billable hours across prosecution and contentious work; the firm does not publicly disclose pricing or revenue, retains no external investors, and maintains professional liability insurance with R+V Allgemeine Versicherung AG. Operating information systems include Microsoft Teams for communications, ProCall Enterprise for on-premises UC, and standard office tooling — no proprietary technology product is sold.
