While (technically qualified) patent attorneys are responsible for issues relating to validity, infringement proceedings require the involvement of (legally qualified) attorneys at law. This entails a very close collaboration between these two different types of attorneys. They represent their clients in both proceedings as a team and complement each other in all legal and technical matters.<\/p>\n<p>BOEHMERT &amp; BOEHMERT is one of only a handful of law firms in Germany that provides a combined representation by both types of attorneys. The seamless collaboration in teams that consist of specialized attorneys at law who are experienced in litigating patent cases and patent attorneys who have the technical expertise guarantees an effective handling of all legal disputes relating to patent law.<\/p>\n<p>We provide services in all areas relating to patent and utility model litigation. At an early stage, applications are frequently structured in a way that they can be best enforced in the event of a dispute. We provide comprehensive assistance as disputes arise (which includes the development of different dispute resolution strategies, including informal notifications of infringers, warning letters, protective letters and preliminary injunctions). We represent our clients in all infringement and nullity matters, both before German courts and the German and European Patent Offices.<\/p>\n<p>Our large network of associated law firms, which has been established and tested out for many years, helps us coordinate and frequently assist with foreign and multinational legal disputes.<\/p>\n<\/div><\/section><\/p><\/div><div class='av-flex-placeholder'><\/div><div  class='flex_column av-51rgm-2564bf8f1abb2f3264864c8311d98759 av_two_fifth  avia-builder-el-11  el_after_av_three_fifth  avia-builder-el-last  lightblue-box flex_column_table_cell av-equal-height-column av-align-middle'     ><\/div><\/div><!--close column table wrapper.
