RGTH

RGTH is a German IP law firm founded in 1873. With offices in Hamburg, Munich, Frankfurt, Düsseldorf and Berlin and 18 attorneys, we help companies win the European IP battle—before the EPO and in court. Our team blends first rate technical depth across mechanical and process engineering, electronics and software, and chemistry/biotech/materials with sharp litigation judgment. We prosecute patents, utility models, designs and trademarks, but we are equally built for disputes: oppositions, nullity actions and, crucially, Unified Patent Court (UPC) proceedings. We act for plaintiffs and defendants, shaping pan European enforcement and defence strategies, from urgent injunction work to merits and validity. Recent highlights include representing JinkoSolar against LONGi Green Energy in UPC litigation concerning unitary patents for advanced solar cell and module technology. Expect clear risk calls, decisive next steps and efficient cross border execution—fast, pragmatic, and aligned with business objectives.
