Firm overview

History
In 1966, Ernest T. Freylinger laid the foundations of our present industrial property consulting office in Luxembourg.

With the help of his wife who wrote letters on a typewriter, Ernest T. Freylinger prospected in Luxembourg and all around the world trying to convince many companies about the importance of protecting their intellectual assets.

Over the following years, Ernest T. Freylinger managed to gain the confidence of important clients in Luxembourg and created business partnerships with other IP offices, mainly in Luxembourg and in Belgium.

These collaborations allowed the office to expand its services on an international basis. Office Freylinger has continued to grow and now relies on a wide range of national and international clients, from the corner shopkeeper up to the multinational company.

At the turn of the century, the rejuvenation of the staff, new openings in the fields of industrial property as well as a constant improvement and variety of the provided services have contributed to place Office Freylinger as the main and largest Luxembourg IP Office.

Values
We assist our clients in developing adequate Intellectual Property strategies to help them in acquiring and expanding strong market positions.

Our core values are: SECURITY, PLEASURE and CREATIVITY.

We provide tailor-made services to vigorously protect our client’s rights and interests. We strongly rely on our highly qualified and motivated IP attorneys and paralegals to provide high quality work for our clients.

Quality
Having been involved in numerous opposition/appeal proceedings and infringement cases, we know how important it is to carefully draft and amend intellectual property right applications during their prosecution.

Our philosophy is that IP rights are commercial tools, which must be able to furnish a return on investment. This return on investment can be achieved by capitalising on a monopoly, by giving licences to competitors and/or by enforcing patent rights against infringers. All these actions are only possible if the rights are carefully drafted.

Quality control
Having numerous direct clients requiring our services, the quality of our services is one of our most important assets. Quality generates trust from our clients and trust is the most essential requirement in our profession.

Confidentiality
Each employee is bound by the provisions of the Luxembourg law and has a strict confidentiality clause in his or her employment contract. The fact that the confidentiality of our work and of the information given to us by our clients is a crucial factor is regularly reminded to the team.

Optimizing expenses
Optimizing expenses is a permanent concern. Therefore, as from the early beginnings of our work, we keep a close eye on expenses affecting our clients.

Our ability to directly act before many national Patent and Trademark offices in Europe allows us to minimise the costs to the client for numerous actions performed before these offices.

For providing services in the rest of the World, we rely on a broad network of confirmed foreign associates, which are respected members of the various professional organisations. Our clients benefit from our transparency in cost matters as well as from our reasonable rates.
