Patent law

Lorenz Seidler Gossel offers comprehensive advice in all matters relating to patents and utility models and represents clients before German courts. Our attorneys-at-law and patent attorneys accompany companies and developers from the first application for the patent or utility model to the drafting of corresponding license agreements and up to the enforcing of rights against third parties. We develop individual application and court strategies tailored to your specific industry for this purpose.

We offer special knowledge of the following industrial and scientific fields: Mechanical engineering, automotive technology, medical engineering, physics, electrical engineering, electronics, general mechanics, chemistry, telecommunications, computer-implemented inventions, material sciences.

Patent applications
We have worked for many years in a wide range of fields in application practice before both the German patent office and the European patent office; we have a correspondingly large amount of experience in drafting patent applications and in all aspects of the examination procedure. Using our global network of specialized colleagues, we also file and prosecute patent and utility model applications outside Germany for our clients. In this regard, we have a great deal of experience in managing extensive international patent families and offer corresponding in-depth knowledge not only in the classical patent countries such as the USA, Japan, China and Korea, but also in countries less know for patents such as Brazil, India, the CIS states or the Gulf region.
Opposition and nullity proceedings
Another traditional focus of our work is the representation of our clients in opposition and nullity proceedings before the EPO, the German Patent and Trademark Office, the Federal Patent Court and the Federal Court of Justice. We combine substantiated technical arguments with in-depth knowledge and many years of experience in the increasingly important procedural aspects and pitfalls of legal proceedings to prepare for our work in opposition and nullity proceedings.
Infringement suits
Our attorneys-at-law and our patent attorneys all have extensive experience in infringement procedures in which we either enforce the IP rights of our clients against infringing parties or defend our clients against unauthorized use of such rights. Our attorneys-at-law have also been consulted for many years by external patent attorneys in infringement suits. Two of our attorneys-at-law also have degrees in technical subjects and so provide correspondingly extensive technical know-how, too. Our own clients enjoy the services of a team of attorney-at-law and patent attorney who can therefore offer joint expertise without any losses in transmission and without any red tape.
Expert opinions on the protective capability and the infringement situation
We give our clients expert advice on the protectability of their inventions and any risk of infringing third-party rights. We use experienced research staff to prepare expert opinions and freedom-to-operate analyses.
R&D contracts, license agreements
We work together with our clients to develop tailored contractual solutions for cooperation with other companies in the development or marketing of their products and for the exploitation of their patent portfolio.
Employee invention law
We advise companies with respect to the setting up and implementing of administrative and incentive structures for dealing with employee inventions and act for employers and employees in disputes about the compensation for employee inventions.

Competition law

Competition law protects the integrity of the market and ensures fair competition. It focuses in particular on fair competition, the prevention of unfair practices, and the enforcement of legitimate claims.

Competition law not only protects your own rights, but also helps to ensure that marketing, advertising, and sales activities comply with the law.

Software law and IT

Legal questions relating to all aspects of trademarks, competition and copyright protection play a significant role in the areas of information technology and the internet. The know-how we have acquired over the years in the classical IP disciplines is complemented by our high expertise in connection with new technologies.

Copyright

Copyright protects intellectual creations in literature, science, and art. It grants the author personal and economic rights to their works, regardless of whether they are registered or not.

Design law

A strong design is often the first impression a product makes on customers—and is therefore a decisive competitive factor. Design law protects this creative achievement and ensures that creative ideas cannot be freely imitated by competitors.

Unitary Patent

With the Unitary Patent and the European Patent Court (EPG), it has been possible for the first time since 2023 to enforce patents with uniform effect centrally in large parts of the European Union. We offer comprehensive advice and support with regard to the new European patent court system and its advantages for your international patent applications. You can find our information brochure on this topic here.

Trademark law

We can offer our clients a full-service in all areas of trademark protection and will stay at your side from the creation of a mark to its registration and its enforcement.
