67895 patent applications have been filed at the German Patent Office in 2018.

Patents and utility models

67895 patent applications have been filed at the German Patent and Trademark Office in 2018. Each of these patent applications had their own motivation. Protection of technological progress. Basis for technology sales. Protection of the investment for the development costs. Employee Inventions. One thing is in common to all of these patent applications: Due diligence needed in the preparation thereof, because the possibilities for amendments are limited to the disclosure at the filing date.

We advise creative minds and innovative companies to possibilities for protection of their inventions and outline the appropriate filing strategies. So it may be advisable from an economic viewpoint, to register a utility model instead of a patent.

A core task are searches for the state of the art documents and the assessment of search results. We also perform as part of the portfolio management extensions and monitor the patent activities of the competition. The defense and enforcement of patents, we take over in all warning letter, interim disposal as well as in litigation. We are glad to advise on the layout of license agreements and contracts relating to research and development collaborations, etc.


Trademarks are quality promises and the basis for successful marketing your goods and services. The focus is on your customer recognizing your products and services via your trademark. Secure your brand in the business via the registration of a trademark. We assist you building a trademark strategy in regard to your business sector, starting with advice on registration options, on the search in respective registers, on the appropriate formulation of the list of goods/services and on the application process in Germany, Europe or Worldwide. We do advice in all matters of trademark law. We also perform as part of the portfolio management collision monitoring and renewals for you.

Many years of experience we rely on in upholding and enforcing brands in all adversary proceedings and in regard to of brand exploitation through licensing agreements.

Dr. Petri holds a lectureship for trademark and media law at the Julius-Maximilians-University of Würzburg and at the University of Applied Sciences Würzburg-Schweinfurt.


Do you trust in your product? Then have the courage to apply for a trademark!
The influence of design on the market success of a product has never been more than today.


The influence of design on the market success of a product has never been more than today. A stylish design is "sexy" and distinguishes your product from the competing crowd. For effective design protection, the distinct visual features need to be filed at the register. Protect your product design effective against imitators - in the internet or at trade shows. In all aspects of the design law, we have extensive experience. Prior to filing, it is possible to perform searches for known designs. If there are no obvious concerns to the novelty and individual character of your design, we can advise you on the different registration options in Germany, the European Union and other countries throughout the world.

Design protection can often be operated with relative little efforts, but is a perfect protection against piracy. Hence, for more and more applicants, design protection gets into focus - and rightly so. Talk to us! We look forward to your creativity.

Competition law

In the daily competition for market share, the fight for the "pole position" is fought with hooks and eyes. Some of the competition overshoots! So their action may be objectionable under the laws on competition, for example, misleading advertising claims, superlativ claims, reduction of competitors, slavish product imitations or the use of trade secrets. Together, we are committed to fair competition and decide together how you can enforce your rights in the most sensible way. We do check your advertising terms in view of competition law, defend you against warning letters or interim injunctions or file interim injunctions in your name and enforce your claims in court.


The competition for market share is fought with hooks and eyes.

Contract law is a matter of trust. Trust us!

Contract law

Intellectual property rights are not registered for their own sake.

The focus is on the systematic exploitation of the own intellectual property right position - usually by the sole own use or the granting of manufacturing and distribution licenses for third parties. We are glad to check and work out with you exploitation contracts on patents, trademarks as well as designs, represent you in contract negotiations and enforce your claims in courts. This applies, in particular, to contracts for the transfer of intellectual property rights.

Another focus of our work is the support of R & D cooperation’s between different companies, businesses and individual inventors or between companies and universities.

Contract law is a matter of trust and lives of lawyers' experience. Trust us!


„To think means to compare“ (Walther Rathenau)

We stand any comparison - but no one can do everything. That's why we do only what we really can! Our core activity is the worldwide prosecution and litigation of intellectual property rights such as patents, trademarks and designs. We also advise these rights, i.e. in the outline of licensing contracts or research and development contracts, but also in sales contracts and in competition, copyright or advertising law as well as in the employee inventors law.

We have experience. We advise world's leading companies build an effective intellectual property portfolio and develop patent, trademark and design strategies that exactly match the interests of our clients. Different clients have different interests. We know that.

Compromise is good - but not always the silver bullet. Careless settlements and convenient flexibility endangers in the long run your competitive position. We have special expertise in the legal enforcement of claims under the patent, trademark, design, competition and contract law. We know how your opponent ticks and we know the courts.

Legal work costs money. And money, one need to talk about. In general, we work on the basis of payment arrangements; for certain projects also fixed prices can be agreed. Before the start of our work we calculate the costs as precisely as possible and let everyone know for what it is. In a good client-attorney relationship there is no arguing about money.

We look forward to seeing you!
