Stay informed on current IP issues.

All news


For more than 90 years our clients have been coming to us for advice in the fields of patents, trademarks and designs, something which cannot be taken for granted even given the long history of our practice, which was founded in 1928. We therefore feel all the more privileged to have worked with most of our clients for decades.


We have a diverse range of clients – and that is true in more ways than one: we advise our clients all the way from a start-up to a medium-sized business to a multinational company. Our clients are based both at home and abroad and are experts in a huge variety of fields.


As a client of LBP, you naturally benefit from our global network of associate attorneys, built up over decades, which enables us to cover all types of IP rights in all kinds of technologies and in all the countries of the world.


Karlsruhe is the centre of a young, modern technology region having a flourishing economic structure mainly of medium-sized enterprises. Many of these businesses are highly innovative and are international market leaders in their specialist areas.

Meet our team


We provide legal consultation and support in all areas of intellectual property rights. This activity includes:

IP – Intellectual Property

We advise you as to the most appropriate IP right for your product and support you all the way from application to grant and of course beyond!

Intellectual Property Advice

Working in close co-operation with you, we formulate the appropriate IP applications for your invention, your trademark or your design and guide you all the way through to grant or registration – worldwide too!

Enforcement of Your Rights

Our strong team of patent attorneys has the required expertise and the necessary resources to assist you in monitoring and enforcing your own patents, trademarks and designs and in defending them against the IP rights of your competitors.

Defense against Third Party Rights

We review your product to draw up valid non-infringement arguments and develop suitable defensive measures which may, of course, also include counter-attacks.

Contracts and Agreements

Many potential disputes can be settled privately or out-of-court by a mutual agreement in advance of offcial or judicial proceedings. This way of avoiding disputes is a particular focus of our legal practice at LBP.

IP Valuation

The valuation of intellectual property rights – especially patents and trademarks – requires sound legal know-how. We have the competence and practical experience to record property rights in monetary terms, to examine them qualitatively for their value and to assess the risks that may be associated with them.
