Legal services

Labour Law

Thorough legal advice on labour law
We advise companies on all aspects of individual and collective employment law. We consider ourselves more than just legal advisers of the company but as “sparring partners” of our clients to exchange ideas at any time.
Our advice is generally aimed at preventing conflict. If the desired results cannot be achieved out of court, we will enforce your rights in court. Thanks to our long-standing experience, we can develop the right strategy for any proceedings.
Collective employment law
Another important focus of our activities involves negotiations with employee representative bodies and equivalent bodies for public sector employees. If an agreement cannot be reached, we will enforce your rights before the arbitration committee and in court proceedings.
Business immigration
We assist both companies looking to attract qualified experts from abroad and expatriates wanting to work in Germany. Thanks to our proven expertise in this legal area and years of close cooperation with both the local immigration authorities and the numerous diplomatic missions (embassies and consulates), we can often facilitate a faster and smoother start into a new position.
Termination of employment contracts
We assist companies, company bodies and senior managers in the (imminent) termination of employment relationships. We develop strategies and then rigorously implement them. Our expertise is not limited to out of court advice but also includes the conduct of unfair dismissal proceedings.
Social security law
Numerous areas of social security law directly intersect with employment law. We give full consideration to these areas to ensure our clients receive the best possible advice.
Contract drafting
We draft and review employment contracts, bonus schemes and agreements on objectives. We also have proven expertise in drafting contracts and variable compensation components for company bodies – particularly the board and managing directors.
Use of external staff
We advise on all aspects of using external staff and draft the required contractual provisions for you. In addition, we represent your rights in relation to the supply of temporary workers before public authorities and in court.
The present times are characterised by the fast pace of life. Companies must always be prepared for sudden changes and act accordingly. We assist you in this aim and support you in all restructuring processes.
International employee secondments
Globalisation has a significant impact on the labour world. It leads to an increasing need for cross-border employee secondments. We create the necessary legal framework in these scenarios, e.g. by drafting the relevant contracts or communicating with public authorities to obtain the required documentation. Moreover, we can rely on a well-established network of colleagues who can advise on the employment law provisions applicable at the place of secondment.

IP/IT/Media Law

Patent law

We enforce our clients’ patents against infringement by third parties both before the national courts and the Unified Patent Court (UPC). In addition, we represent our clients against warning letters, preliminary injunctions or lawsuits for alleged patent infringement. We carefully analyse the infringement situation and advise both on FTO as well as during ongoing patent infringement proceedings (Second Opinion). In addition, we cooperate with experienced patent lawyers belonging to our well-established network to represent our clients in legal validity proceedings (Rechtsbestandsverfahren) in patent offices and courts.

Trademark law

With effective measures we defend your trademark against infringers and product pirates. In addition, we represent our clients against groundless warning letters, preliminary injunctions and lawsuits for alleged trademark infringement.
We also advise you strategically with respect to developing your national or international trademark portfolio. Where conflicts involve third countries, we rely on our well-established network of experienced colleagues in nearly all countries in the world.

Unfair competition (UWG)

We provide thorough advice on unfair competition, particularly in litigation proceedings. We advise on effective action against competitors’ unfair practices and we represent our clients against groundless warning letters, preliminary injunctions and lawsuits for allegedly unfair competition practices. In addition, we provide preventive advice to ensure compliance with relevant legal provisions, in particular with regard to advertising (off- and online).

Design law

We defend your design rights against infringers and product pirates. In addition, we represent our clients against groundless warning letters, preliminary injunctions and lawsuits for alleged design right infringement. We also assist you with the registration of German, European and international designs. We also assist you in developing of the right registration strategy for your national or international design portfolio. Where conflicts involve third countries, we rely on our well-established network of experienced colleagues in nearly all countries in the world.

Copyright and Media Law

We advise on all aspects of Copyright and Media Law, both in and out of court. Our particular areas of focus include the drafting and review of contracts granting rights (testimonial contracts, buy-out contracts etc.) and the enforcement of Copyright.

We advise and represent both companies and individuals against unfounded defamatory statements by third parties. In addition, we also provide preventive advice on defamation law issues, e.g. on press releases about ongoing court proceedings.
IT Law

We advise on issues relating to Information Technology Law, e.g. on software projects or IT contracts in e-commerce. Advising innovative start-ups is a focus of our activities.

Contract Law

We draft contracts in the abovementioned areas, e.g. licence agreements, non-disclosure agreements, R&D contracts, advertising and testimonial contracts and cooperation agreements. We also represent you in legal disputes relating to these types of contracts.

Labour law & IP/IT/media law
Employees’ inventions law
We advise and represent both employee-inventors and companies in matters relating to the employee’s inventions law. One area of our focus consists of advising companies on how to deal with typical employee’s inventions and on inventions by corporate bodies. We draw up customised guidelines for our clients that provide details on how to register and claim an invention and how to remunerate the inventor. Thanks to our dual expertise, we always give due consideration to the aspects of labour law . In disputes regarding the inventor’s right to remuneration, we represent our clients in both the courts and the Arbitration Board of the German Patent and Trade Mark Office.
Protection of (employee) data
We advise companies on all data protection issues, particularly protection of employee data. The potential ramifications of mishandling data have become considerably more serious for the parties involved since the General Data Protection Regulation (GDPR) entered into force.
We can assist you in designing and implementing internal processes that ensure that data is processed in accordance with the law, with a specific focus on employee data.
Moreover, we can represent you in disputes before data protection agencies and enforce your rights in court if necessary.
Protection of trade secrets
We advise companies on the protection of their trade secrets. Compliance with the new statutory requirements is of particular significance in this regard. To this end, we prepare customised guidelines and instructions for your company, which ensure that trade secrets are effectively protected.
In addition, we can rely on our experience of representing clients in numerous proceedings relating to the protection of trade secrets. We represent you before employment and civil courts to enforce all claims relating to the unlawful disclosure of trade secrets, in particular in claims for injunction, disclosure and damages. When the unlawful disclosure of trade secrets is suspected, we can conduct inspection proceedings if possible, to collect evidence for our clients. Moreover, we advise on the criminal aspects of the protection of trade secrets when enforcing our clients’ rights.
Non-competition covenants
We advise comprehensively on competition issues involving current or former employees, company bodies and shareholders. In this context, we advise our clients on the legal options regarding contractual and post-contractual non-competition covenants and draft the required agreements.
We also represent our clients in litigation disputes, both to enforce non-competition covenants and to challenge invalid non-competition covenants.
IP compliance
Another focus of our activities regards liability risks due to the infringement of intellectual property rights (patents, registered patterns, trademarks, designs). In the last few years, the liability of company bodies (e.g. managing directors) has been the subject of numerous rulings of the higher and supreme courts. We advise on this very issue from both an IP law and an employment/service contract law perspective.
The prerequisites for liability and measures to avoid liability must be carefully considered. Depending on the intellectual property right affected, these are treated differently by the civil division of the Bundesgerichtshofs.
In addition to civil law aspects, we also advise on criminal liability for infringement of intellectual property rights. Our advice is aimed at both companies and criminal defence lawyers who request intellectual property expertise in ongoing proceedings. It should be noted that the essential prerequisites for criminal liability correspond to those for civil liability. Calling in civil law expertise can add significant value in this context.
