Maikowski & Ninnemann – Germany 2021

JUVE Comment

This pure patent attorney firm is undisputedly one of the market-leading outfits when it comes to litigation in technical matters in major patent suits. Few mobile communications cases of high economic importance occur without its involvement. Apple and LG, for example, entrusted the patent attorneys with additional proceedings. Only a few patent attorney firms, such as Samson & Partner, have a similar visibility in SEPs and FRAND proceedings. The patent attorneys mainly advise patent users on defending NPE suits. In exceptional cases, e.g. for LG and Hoccer, they work on active suits involving telecommunications patents. The activity for LG could offer further potential if the Korean company discontinues its mobile communications business and exploits its patents more.

Maikowski & Ninnemann underscored its preeminent expertise in mobile communications by representing Continental as one of Daimler’s most important suppliers in connected cars proceedings. Younger patent attorneys, such as Christoph Schröder and Andreas Tanner, used these varied activities to strengthen their market profiles – an important step as the market’s perception of litigation work has focused too heavily on Gunnar Baumgärtel for many years.

Intensive litigation work in the mobile communications sector is offset by a technically broad prosecution practice. Maikowski & Ninnemann has consistently secured this, too, by establishing new offices with young patent attorneys. The appointment of a patent attorney to equity partner in Frankfurt underlines the success of this expansion. Opening an office in Düsseldorf would be a consistent next step in view of litigation work.


Litigation related to mobile communications. Technical expertise in telecoms, semiconductors and engineering.

European strategy

With its litigation experience and strong ties to most relevant litigation firms in the German market, Maikowski & Ninnemann has moved into position for advising on many international disputes. The firm also intensified connections to technology corporates like Apple, Google and LG to reduce its dependence on law firms such as Hogan Lovells, for instance, which are integrating their own patent attorneys. Still, Maikowski & Ninnemann also banks on a self-sufficient patent attorney practice and strengthened its patent filing work in other technical areas, so it is less dependent on other firms.
