What we offer

Oppolzer | Seifert  specializes in German and European competition law.


Cartel Investigations

Oppolzer | Seifert represents and defends clients in cartel investigations by the German Federal Cartel Office or the European Commission as well as before German and European courts. We can assist you in the event that your office or home is subject to an unannounced inspection by the competition authorities.  

We advise clients in relation to all forms of alleged anticompetitive behavior, be it horizontal cartel agreements, vertical restraints or the abuse of a dominant market position.

Cartel Damage Litigation

Oppolzer | Seifert represents customers or competitors that have suffered damages as a result of competition law infringements. We lead settlement negotiations and, where necessary, enforce our clients‘ claims in court. 

We have extensive experience in the representation of claimants (e.g. in the cartel cases regarding TV-advertising, sugar, and trucks) and have longstanding and close contact and relationships with leading competition economists and litigation funds, enabling us to offer you a comprehensive one-stop service in the recovery of damages.

Merger Control

Oppolzer | Seifert files merger notifications with the German Federal Cartel Office and the European Commission. Where transactions require merger clearance in multiple jurisdictions we can rely on a longstanding international network of leading antitrust counsel. 

We also examine mergers planned by third party companies and make sure your competition concerns are heard in the authorities‘ merger control proceedings and, where required, through appeal procedures. 

Joint Ventures and Cooperations

Oppolzer | Seifert devises joint ventures and drafts cooperation agreements between competitors, e.g. regarding joint research and development, joint production or purchasing.

Distribution Agreements and related Competition Law

Oppolzer | Seifert reviews existing and proposed distribution agreements and drafts tailor-made distribution systems compliant with competition law.

We examine long-term or exclusive supply-contracts and advise and represent clients that are affected by anticompetitive delivery or purchase restrictions. 


Oppolzer | Seifert conducts antitrust compliance trainings for executives and (sales) staff and supports clients in the implementation of tailor-made compliance management systems. 

If an antitrust infringement is suspected, we investigate internally and – if need be – file leniency applications with the German Federal Cartel Office, the European Commission and competition authorities in other jurisdictions.
