Maikowski & Ninnemann – Germany 2020

JUVE Comment

This patent attorney firm is one of the market-leading names when it comes to the representation of technical aspects in big-ticket patent litigation. There are few economically important mobile communications cases it is not involved in. The patent attorneys represent many notable industry giants in the shape of Apple, Google, HTC, Lenovo and Vodafone – chiefly in the defence against NPE suits. For LG and Hoccer, on the other hand, they are involved in active suits concerning mobile communications technologies. Just how well the firm is established among important law firms, as well as among companies, is shown by the fact that it represented Google alongside Quinn Emanuel concerning an important Android feature. The law firm generally conducts litigation without external patent attorneys. The firm underscored its outstanding mobile communications expertise with work for Continental as one of the main suppliers to Daimler in the current connected cars proceedings. Besides rigorous litigation work in the mobile communications sector, the firm operates a technically broad prosecution practice. Maikowski & Ninnemann has consistently safeguarded this by establishing new offices with young patent attorneys in traditional fields of technology: last year it launched in Frankfurt and quickly landed more prosecution work from Rhein-Main industry. Opening a Düsseldorf office would be the next logical step.


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 international disputes. The firm also intensified connections to technology corporates like 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.
