JUVE Patent

Ampersand – Germany 2020

JUVE Comment

The well-positioned team at this small Munich IP boutique around Hosea Haag enjoys a solid market position thanks to his close ties to NPEs like Unwired Planet in mobile communications suits. The firm filed an impressive number of new mobile communications suits for Invte, Onebutton, Uniloc and Wsou Investments. Ampersand has therefore gained a great deal of experience in SEPs and FRAND aspects for plaintiffs. Litigation for Mittelstand companies is also part of the core activity, with frequent work involving complex patents, e.g. in optics. Development in this line of work was static, however, for the small team, as litigation for NPEs kept it busy. Although the firm gained some room to develop further work by naming a second partner, the loss of an up-and-coming associate, who started his own firm, was a setback in 2020. The hiring of a young lawyer has only partly compensated for this. The patent team will have to raise its headcount if it wants to strengthen its mainstay – work for industrial clients.


Litigation for NPEs regarding mobile communications, including SEP and FRAND claims.

European strategy

The nationally independent litigation boutique is well versed in operating in mixed teams from various firms, thanks to its litigation for NPEs in major proceedings. It is thus relatively independent of conflicts of interest and could continue to be the first choice for NPEs at the UPC. These clients are expected to use the new court intensively.
