karo IP Patentanwälte Kahlhöfer Rößler Kreuels PartG mbB

With more than 20 years of experience in the world of intellectual property, the experts of karo IP combine technical and scientific competence and practical know-how in all areas of IP law. The range of the firm’s activities include the prosecution, enforcement and litigation of all types of IP rights (patents, utility models, trademarks, designs), as well as employee invention law and licensing.

The internationally experienced patent attorneys advise companies especially in the automotive and telecommunication sector, with emphasis on futuristic technologies in these fields, such as industry 4.0, smart devices, Internet of Things, medical devices, autonomous driving and communicating cars/vehicles.

karo IP

The firm, based in Dusseldorf and Munich, aims to develop and implement innovative ideas for providing clients with efficient, in-depth and proactive advice. The core IP team has been successfully working together for over 15 years. All attorneys are well experienced German and European patent attorneys covering all fields of technology – with a special focus on physics, engineering, information technology and medical technology.

Some 11 highly adaptable attorneys with a wide-ranging and complementary set of skills make the core of the practice, with teams put together on a case-by-case basis. Supported by highly qualified patent engineers and paralegals, the patent attorneys ensure that the best possible protection in both technological and economic terms is afforded.


karo IP has profound knowledge in patent prosecution. The firm manages contradictory proceedings before patent offices and patent courts, as well as multinational infringement matters worldwide. The practice focuses increasingly on the enforcement of IP rights in the field of mobile communications and the Internet of Things, among others, in Germany.

IP rights also play a progressively important role in mergers and acquisitions. karo IP gives attention to the rising demand of freedom-to-operate analyses (eg, for product launches in Europe) and the management of large patent portfolios. The firm’s patent attorneys analyse IP portfolios for potential legal risks and support its clients’ corporate management through due diligences such as during M&A procedures. Patent litigation work is also an increasingly busy practice area, with the firm frequently participating in major patent disputes in Germany.
