JUVE Patent

König Szynka Tilmann von Renesse – Germany 2019

JUVE Comment

This patent attorney firm from Düsseldorf stands out for its outstanding reputation for litigation, predominantly for pharma and biotech clients. The name partners in particular are extremely visible and regularly represent core clients such as Bayer and Eli Lilly in oppositions and infringement cases over economically significant medicines. The firm is well versed in coordinating international proceedings – a role which usually falls to lawyers and which shows just how well the boutique’s patent attorneys are anchored among its clients. The patent attorneys also have a solid work flow in filing for a loyal client base.


Litigation by patent attorneys, often in cases of a precedent nature, primarily for biotech and pharmaceuticals companies; mechanics patents.

European strategy

Even without international cooperation and foreign offices, KSTR is excellently equipped for the UPC, as its outstanding reputation for litigation in pharmaceuticals and mechanics patents secures many direct contacts to companies. KSTR also works with several law firms. Of these, only Hogan Lovells is so far building up its own patent attorney team for litigation. But KSTR will have to keep an eye on the trend among law firms of establishing mixed litigation teams to protect its strong position.
