The two merging partners of the law firm Kraus & Lederer, Lederer & Keller and Kraus & Weisert, can look back on decades of successful consultancy work in the field of intellectual property law.

Lederer & Keller was founded in Hamburg in 1934 by Dr van der Werth. Dr Lederer moved the office to Munich. Lederer & Keller was last located in Unsöldstr. in Lehel in Munich.

Kraus & Weisert was founded by Dr Kraus and Dr Weisert who, with the opening of the European Patent Office in November 1977, began representing a number of US and Japanese companies before this important international institution. The first European patent application filed by Kraus & Weisert for a US client was dated 1 June 1978 and was the 19th patent application received by the EPO.

Today, Kraus & Lederer represents and supports clients from all over the world with a comprehensive range of outstanding patent services for Germany, Europe and the world market.

Munich is Germany’s high-tech capital and one of the leading business centers in Europe. This city is home to many international companies and important administrative organisations. The European Patent Office, the German Patent and Trademark Office and the German Federal Patents Court are all located here.

These important institutions are within a few minutes of Kraus & Lederer’s offices. This is a genuine advantage, as we think that the best way to communicate when accuracy and speed are decisive is often a personal conversation – and this is equally true of our work with clients.

Munich is the center of patenting in Germany and Europe.

Ever increasing innovative activity is reflected in the rising number of patent applications filed both with the German Patent and Trademark Office as well as the European Patent Office. Around these two Munich institutions, a patenting infrastructure of huge international importance has evolved.

Kraus & Lederer is there for you.

Munich - A business center of inspiring quality.
