About Us

Kather Augenstein was founded by five established IP specialists at the beginning of 2016 and by now consists of 12 lawyers, who combine their expertise and experience for you. All of our lawyers have many years of experience acting in major cases for significant clients. Our size means that we are much more flexible than many large law firms.

We relish the challenging cases. Our passion is to disentangle complex situations, to decipher apparently contradictory facts, and to get to the root of a problem. We delve into the matter and never give up. Our focus: patents, trademarks, design and unfair competition. When it comes to intellectual property rights, we are second to none – all of us are specialised in this field.

We are a focused and very powerful team with the experience and know-how of the largest law firms. We work closely together, are highly specialised, and combine our knowledge effectively to your advantage. Naturally, this includes issues of international reach as intellectual property does not stop at borders. We work seamlessly with similarly experienced law firms around the world and coordinate international legal disputes.

We are thus able to supervise major mandates with complex issues. In court litigation we do not only master the strategy, we will also bring our creativity and ideas fully to the fore, to get the best possible outcome for you.

We work exclusively in litigation, because we prefer contentious disputes. Contentious and complex proceedings require a special approach and organisation. We appreciate your concern that your interests may not be heard with sufficient care and, also, the stressful situation and heavy pressure that legal disputes entail. We are aware of the impact that a dispute over monopoly rights may have, especially if a ban on production is at stake. We also have extensive experience with arbitration. We are regularly nominated as arbitrators, and are thus familiar with the other side of the bench.
