IAM Patent 1000: The World’s Leading Patent Professionals 2019:
Making its way onto our firm table for the first time this year is Stuttgart-based boutique Unit4 IP, which has recently been wowing clients with its flexible, personalised and top-quality litigation and transactional work. Unit4 already has excellent links with Mittelstand companies in the area and is starting to gain wider renown among larger German firms. Infringement and licensing agreement maven Arno Grohmann is at the heart of the firm’s activities, as one satisfied client attests. “He a truly clever strategist, an excellent litigator and a real game changer. Besides his profound legal expertise, he also has deep technical and commercial knowledge. With his pragmatic and thoughtful approach, he is of indispensable value for us.”

WTR 1000 The World’s Leading Trademark Professionals 2019:
UNIT4 IP has become a formidable player in German intellectual property. The trail-blazing boutique advises corporate companies from an array of industries – automotive, computing, pharmaceutical, fashion, retail and publishing – and is particularly popular among global players from the United States. Notable clients include Gilead Sciences, YUM! Brands, easyGroup and Intel. In a huge development for the practice, it also recently took over worldwide management of the portfolios of Porsche and Bugatti International. Jan Weiser, Ursula Stelzenmüller and Ekkehard Stolz are all rainmakers. Weiser builds impregnable portfolios brick by brick in close cooperation with business executives, then expertly fends off challenges from competitors in the courtroom. The “extremely impressive” Stelzenmüller “approaches disputes practically and achieves resolutions that make sense for her clients. She is always a real pleasure to work with.” Stolz is another “stellar lawyer” with “a wealth of experience” under his belt; when it comes to parallel imports issues, there are few in his class.

JUVE Handbook German Commercial Law Firms 2018/ 2019:
"2.5 years after the firm was founded, the former Lichtenstein Körner lawyers, also known as Unit4 IP, have succeeded in establishing themselves in the classical field of Soft IP and trademark law. This is due to the fact that they further sharpened their profile, with a focus on trademark administration, strategic consulting and trademark infringement suits, and thus were able to acquire additional renowned clients. Publicly known is the activity for Amazon in formal trademark law, and also for Porsche and Bugatti the firm is active in trademark prosecution and enforcement. (…).“

Juve Handbuch Wirtschaftskanzleien 2016/2017:
„Die als Spin-off von Lichtenstein Körner Anfang 2016 gestartete Kanzlei konnte sich auf die Treue ihrer langj. Mandanten verlassen, die oft aus den USA kommen. Aber auch einige namh. Mittelständler folgten den jungen Partnern, die die komplette Bandbreite im klassischen IP abdecken. Dr. Ursula Stelzenmüller („Spezialistin für Unions- und nicht traditionelle Marken“, Mandant) ist v.a. mit dem formellen Markenrecht betraut, während Dr. Ekkehard Stolz („bin ihm auch in die neue Einheit gefolgt“, Mandant) u. Jan Weiser stärker in Verletzungsverfahren und im Designrecht tätig sind. Ein weiterer Partner betreut Patentprozesse.“

WTR 1000 The World’s Leading Trademark Professionals 2018:
“After setting up shop in 2016, Unit4 IP has well and truly hit the ground running. It wins plaudits from clients and peers alike for its “extremely clear” advice, enterprising spirit and vitality and has already accrued an impressive client catalogue comprising start-ups, small to medium-sized enterprises and household names from the United States; cracking examples include EasyGroup, Intel, Gilead Sciences and Yum! Brands. They all receive a hands-on, uniquely personalised service from one of the team’s three trademark stars: Ursula Stelzenmüller, Ekkehard Stolz and Jan Weiser. “Stelzenmüller is extremely knowledgeable, professional, experienced and sensitive to clients’ needs.” She maps out creative, effective filing strategies and excels in opposition and cancellation proceedings before the DPMA and EUIPO. Stolz stands out for his ability to “distinguish between the theoretical and real-world risks that proposed marks might throw up” and for the clarity of his advice. A commercially minded litigator, Weiser comes to the rescue when infringement trouble is brewing; he knows how to think on his feet and lets nothing run away from him.”

JUVE Handbook German Commercial Law Firms 2018:
“This firm launched a year and a half ago as a Lichtenstein Körner spinoff and, according to competitors, made a “good start”. The four partners are active in all fields of classic soft IP and expanded existing work massively. The firm is increasingly active in trademark infringement suits, e.g. for an international electronics corporate. The most visible litigator is Dr. Ekkehard Stolz, whom one client describes as a “pivotal partner in trademarks”. In trademark administration and defense, as well as border confiscation, the boutique advises Gap and Banana Republic. The hiring of a new graduate and an experienced associate from CMS highlights the positive development. (4 partners, 2 associates)“

WTR 1000 The World’s Leading Trademark Professionals 2017:
“Founded in January 2016, UNIT4 IP has got off to a fantastic start. The boutique has already cultivated a dazzling clientele featuring both nascent start-ups and world-renowned entities from sectors such as pharmaceuticals, fashion, retail and publishing. Its professionals have extensive experience working with US enterprises and so know how to tailor services to North American practices and expectations. Of late, it has been busy representing businesses before the EUIPO and tackling tricky domain name matters. Ursula Stelzenmüller assuredly guides clients through both contentious and non-contentious mazes; she is a noted anti-counterfeiting hawk who manages large-scale border seizures with finesse. Ekkehard Stolz flies high in pan-European litigation and has invaluable experience across the soft IP field; he serves on the German Association of Intellectual Property and Copyright Law’s Special Committee for Design Law and the International Trademark Association’s Parallel Imports Committee. Jan Weiser has carved out a niche in non-traditional marks, advising on a spate of cutting-edge matters.”
