Arnold & Siedsma

Arnold & Siedsma was established in 1920 and over the past 100 years has become a full-service IP firm, offering prosecution and litigation services in relation to patents, trademarks and designs. Our team consists of more than 60 technical and legal professionals. We operate from the Netherlands, Belgium, Germany and Switzerland

As part of a full-service IP firm, our trademark team explores the best suitable strategy for our clients with a broader view than just trademarks. We benefit from IP awareness that is created in the field of patents as well as litigation, and vice versa. But the broader view also reveals solutions to complex issues that are out of the box. We also dare to say “no” to our clients. We have one goal: to meet our clients’ interest in the best possible way.

This can be achieved only by curious people who embrace new challenges and want to experience what is happening in this new world. People involved with clients’ business, seeing the broader picture and advising how IP suits best and brings most. This approach is the pride of our firm!

ISO 9001 certified

For the past 100 years, we have been a reliable partner to our clients with regard to all IP issues. In 2015 we became the first large Dutch IP agency with foreign offices to be ISO 9001 certified. This certification is valid for all our offices in all countries. We are proud of our ISO 9001 certification because it confirms the high quality of the processes of our operation.

Methodology

At Arnold & Siedsma we believe in customised work and this can be seen in the way we operate: say what you do, do what you say, prove it.

The lines of communication with our specialists are short and personal. Service is our top priority. We stay in close touch with our clients so that we can provide them with a fast and responsive service. At Arnold & Siedsma we follow the four eyes principle, and we will assign a dedicated team to each of your cases. The long-term relationships we foster ensure that we know our clients’ business and strategy, which in turn means that the team will be able to give you the best advice for your business, in line with your multi-annual planning. Our attorneys will maintain regular contact with you. The protection of an innovation is of great economic value, but can also be costly. This is why, at Arnold & Siedsma, we attach great importance to clear communication throughout the entire process and we try to work as cost effectively as possible.

Because we are a full-service IP provider, we handle all IP work. Our patent attorneys, trademark attorneys and design attorneys work closely with our litigation team. We can pull together a team from several disciplines, enabling us to handle cross-discipline IP cases quickly, seamlessly and without unnecessary costs. Arnold & Siedsma is uniquely positioned as a service provider in the Netherlands thanks to this team-based approach.

Arnold & Siedsma is your actively involved and knowledgeable partner. We are happy to be of service and contribute to our clients’ ideas.
