HUASUN is a law firm of patent attorneys and attorneys-at-law. We consult and represent our clients in all the issues of German and European intellectual property rights. The emphases of our work concern patents, utility models, designs and trademarks etc. We also provide legal service in other areas, such as in the area of German corporate law or commercial law.

We are the only law firm of patent attorneys and attorneys-at-law in Germany grounded by person with Chinese background. The law firm was grounded by Yiming Sun. Yiming Sun is the first German patent attorney with Chinese nationality and he is also European trademark & design attorney. Our team members come from China and Germany. Christian Heitzer is one of the very few German attorneys-at-law with exceptional scientific and legal qualifications.

We consult Chinese clients directly in Chinese. As a law firm of patent attorneys and attorneys-at-law, we can competently support Chinese clients especially in all issues of intellectual property rights, which nowadays still remain a weakness for many Chinese companies.

We work closely with many other Chinese and European law firms, which enables us to support you with comprehensive legal service in Chinese and European law.
