KARO IP – Kahlhöfer Rößler Kreuels Patentanwälte PartG mbB

Based in Dusseldorf and Munich, KARO IP – Kahlhöfer Rößler Kreuels Patentanwälte PartG mbB combines practical knowledge and skill in patent law, particularly in automotive and smart technology, with extensive experience in patent infringement matters.

KARO IP was established in 2018 as a spin-off from another well-established patent attorney firm in Dusseldorf. The KARO IP team has been successfully working together for more than 15 years and combines technical and scientific know-how in all IP-rights issues.

All KARO IP attorneys are highly experienced German and European patent attorneys covering all fields of technology, with a special focus on physics, engineering, information technology and medical technology.

Tailor-made solutions

The firm aims to develop and implement ground-breaking new ideas for providing clients with efficient, in-depth and proactive advice. KARO IP develops patent strategies and portfolios, even for such futuristic technologies as autonomous driving, artificial intelligence or blockchain, and represents its clients in all IP-related disputes.

KARO IP offers premium quality that is tailored to the specific needs of its clients. Due to the size of the firm, the core team of nine attorneys with its wide ranging and complementary set of skills is highly adaptable. A team of professionals is put together on a case-by-case basis. Supported by highly qualified patent engineers and paralegals, the patent attorneys of KARO IP ensure that the best possible protection in both technological and economic terms is afforded.

If required, KARO IP can also provide project-related extended teams with specialised patent attorneys and attorneys at law due to close cooperation with ‘best friend’ firms (eg, Braun-Dullaeus Pannen Emmerling).


KARO IP’s clients range from small and medium-sized firms to start-ups and global companies. The team provides engaged, precise and durable work for its clients which are active in different industry sectors, including:

  • automotive (eg, electromobility and autonomous driving);
  • building trade (eg, constructional engineering and smart homes);
  • biotechnology (eg, genetics and pharmaceutics);
  • chemistry (eg, chemical technology and emission control systems);
  • electrotechnology (eg, mechatronics and industry 4.0);

  • computer science (eg, software implementation and mobile communication);
  • engineering (eg, process engineering and construction technology);
  • medicine techniques (eg, imaging and biomechanics); and
  • physics (eg, measurement technology and electricity).


KARO IP has access to a nationwide network of pre-eminent law firms and lawyers specialising in judicial enforcement of IP rights. The firm advises clients in depth and recommends the specialists who are appropriately qualified for their cases. However, KARO IP has no binding commitments to specific colleagues or firms.

Thanks to its international network of cooperating firms, KARO IP can assist clients operating internationally and on short notice ensure that they are represented at international level by specialised lawyers.


KARO IP has profound knowledge in patent prosecution. The firm manages bilateral legal proceedings before patent offices and patent courts, as well as multinational infringement matters in Europe. Its patent attorneys are increasingly committed to the enforcement of IP rights in the field of mobile communications and the Internet of Things, among others, in Germany.

The firm counsels companies, particularly those in the automotive and telecoms sectors, with an emphasis on futuristic technologies in these fields (eg, industry 4.0, smart devices, autonomous driving and communicating cars and vehicles).

KARO IP also gives attention to the rising demand of trademark and design matters, freedom-to-operate analyses and the management of large patent portfolios. An increasing area is KARO IP’s patent litigation work. The firm frequently participates in major patent disputes in Germany.
