"KLAKA is one of the top addresses for legal disputes concerning patent-, trademark-, and design-matters. The highly specialised team convinces with the enforcement of protection rights as well as the defence against unjustified claims. A particular strength of the law firm is the additional specialising on competition law, which is significantly important in the area of standard-essential patents (RAND-objection)."

"Olaf Giebe and Constantin Kurtz are particularly specialised on patent disputes in the areas of electronics and telecommunication. A special strength of both lawyers is, to recognise the essential aspects of highly complex patent disputes, to then develop a matching strategy for the further approach and to correctly place the deciding arguments in procedural documents as well as in verbal negotiations."
