A sign becomes
a right.

We advise companies and private individuals on filing, defending and enforcing their trademark rights. We handle trademark applications ourselves or guide you through them so that all legal requirements are met — and we enforce trademark rights, for example by issuing cease-and-desist warnings (Abmahnungen) or initiating court proceedings against trademark infringements. We likewise defend you against unjustified third-party claims and develop trademark strategies that secure the long-term protection and value of your trademark.

What we do.

01

Filing strategy

Even before filing, strategy determines the value of a trademark: Which form of sign, which classes of goods and services, which geographic scope of protection? We develop filing strategies that fit both trademark and market — including a clearance search.

02

Filing in Germany & abroad

We file trademarks nationally with the DPMA (German Patent and Trade Mark Office), as an EU trademark with the EUIPO, and internationally via WIPO — or we support you in doing so, keeping track of classes, deadlines and formalities so that protection is secure from day one.

03

Defense & enforcement

We defend your trademarks and enforce them — from opposition and cancellation proceedings through cease-and-desist warnings to court proceedings against trademark infringements. We likewise fend off unjustified third-party claims.

04

Business designations & domains

Not every name right arises through registration. We protect trade names and business designations (Unternehmenskennzeichen, §§ 5, 15 MarkenG (German Trademark Act)) and represent you in domain disputes — where the law of distinctive signs and digital presence collide.

Why a trademark

A trademark is often a company's most valuable intangible asset — and at the same time the easiest one to lose. Protecting it early and correctly secures not just a sign, but the value behind it.

Frequent questions.

[ FAQ ]
Question 01
Searches

Do I need a clearance search before filing?

As a rule, yes. A clearance search shows whether earlier rights stand in the way and whether your sign is even eligible for protection. That substantially lowers the risk of later oppositions and cease-and-desist warnings — and protects you from investing in a trademark you cannot keep.

Question 02
Territory

DPMA, EUIPO, or international — which filing is the right one?

A national trademark filed with the DPMA protects you in Germany, the EU trademark filed with the EUIPO throughout the entire EU, and the international registration via WIPO in member states of your choosing. Which option is right depends on your markets and your budget — we help you weigh the options.

Question 03
Warning letters

I have received a cease-and-desist warning for trademark infringement — what should I do?

Take the deadlines seriously, but do not rush into signing a cease-and-desist declaration (Unterlassungserklärung). We examine whether the claim is justified and how far it reaches, and respond accordingly — from a modified cease-and-desist declaration to a full defense.

Question 04
Distinctions

Trademark, business designation, or domain — what protects what?

A registered trademark protects a sign for specific goods and services. Trade names and business designations arise through use (§§ 5, 15 MarkenG). A domain is initially merely registered and can collide with prior sign rights. We bring these layers into alignment.

Question 05
Patents

Do you also handle patents and utility models?

Patent and utility model law is a distinct, highly technical field handled by patent attorneys. We support you there and work together with patent attorneys, but do not take on the technical representation ourselves — our focus is on trademarks, business designations, and domains.
