Patent and Utility Patent Lawyers

CMS Germany has an effective and experienced team of patent and utility patent specialists. Where issues are particularly complex, we work closely with our clients' own experts and with external patent attorneys.

If all else fails, we represent you in court

Our lawyers advise and represent you in infringement cases. We have extensive experience both on the claimant's and on the defendant's side. In other words, CMS has the right strategy for you in any situation.

During preparations for patent infringement lawsuits we provide support by conducting inspections and other preservation of evidence procedures. We also advise you on nullity, opposition and cancellation proceedings.

In urgent cases we can obtain temporary injunctions on your behalf. We also take criminal and civil action against patent infringements. CMS is also the right partner for you in border seizure proceedings.

We can help prevent court cases

In addition to in-court representation, our experts can also provide out-of-court services on your behalf. Examples include:

CMS Germany's lawyers provide ongoing strategic advice on property rights, including employee inventions.

We advise on exploiting your inventions

We advise on, design and negotiate licensing, research and development and cooperation agreements to ensure the best possible protection for your interests.
