Our history
The foundations of Dennemeyer’s extraordinary success story were laid more than 60 years ago in Luxembourg. Since 1962, Dennemeyer has set the service standard for the IP industry and remains dedicated to developing improved ways to protect and preserve IP rights around the world. Initially a patent law firm, we now apply our abilities to the entire chain of IP management as a trustworthy one-stop shop. A succession of innovations has transformed the company headquartered in Luxembourg into one of the world’s foremost IP service providers.

1962 – 1973
Spring in Luxembourg
The story begins. John. J. Dennemeyer establishes a patent law firm in Luxembourg. Business flourishes, the patent world is in full bloom.

It is the time for new inventions, new technologies and new beginnings. Soon, the Luxembourgish patent law firm is becoming a familiar name in the industry, as big clients make it their go-to company for patent-related issues.

1974 – 1984
Seeing the future
The company extends its reach. The first foreign office, Dennemeyer & Co. Ltd., is established in Stockport (UK), where the organization’s first computer-based patent annuity payments are made. The electronic age is dawning, and Dennemeyer & Co. sees what the future needs.

In 1984, the first patent and trademark administration software is released. The world of IP welcomes the new arrival as workflows are streamlined and processes are simplified.

1985 – 2008
Going global
New offices open all over the world for what is maturing into a global company. Tokyo (Japan) in 1987, Paris (France) in 1997, Somerset and Chicago (both United States) in 2004 and Munich (Germany) in 2006 all become home to Dennemeyer offices.

In 1997, the trademark administration software “Hypermark,” the precursor of DIAMS, is acquired. With this pioneering step into the digital realm, the groundwork is laid for what is going to become one of the world’s most powerful IP management systems.

2009 – 2017
Growing further
The Dennemeyer family grows and is now present on almost all continents. The joint venture PAN Asia IP Services Ltd. is created in Beijing (China) in 2010. Meanwhile, Dennemeyer & Associates is established in Brasov (Romania) in 2009 and swiftly expands, with offices opening in Munich (Germany) and Chicago (USA) in 2010, Tokyo (Japan) and Warsaw (Poland) in 2011, Melbourne (Australia) in 2012, Zagreb (Croatia) in 2013, Dubai (UAE) in 2014 and Rio de Janeiro (Brazil) in 2015.

In 2011 the first version of DIAMS iQ is released, making the work of countless professionals a lot less stressful. In the same year, Dennemeyer is awarded the ISO 9001 certification for quality management.

In January 2017, Dennemeyer IP Solutions opens a new office in Singapore. Only a few months later, Dennemeyer & Associates moves onto its sixth continent by opening its office in Johannesburg.

2018 – 2020
New developments
In January 2018, Dennemeyer & Associates further solidifies its global presence with a new office in Paris.

In October of the same year, Dennemeyer acquired Octimine, an innovative startup company that provides cutting-edge patent searching and analysis technology using artificial intelligence (AI). The advanced software is used for prior-art, freedom-to-operate and opposition searches.

December 2019 sees a new member join the Dennemeyer Group: the well-established Italian IP law firm De Simone & Partners. Supporting Dennemeyer’s “glocal” approach, the De Simone brand remains the face of the group in the Italian market while serving as a gateway to Dennemeyer’s international legal and administrative core.

In December the following year, Dennemeyer opens the doors of a new office in Bengaluru (India), offering a local point of contact to clients in a burgeoning market.

2021 – 2023

July 2022 sees the instatement of Dennemeyer’s current CEO, Tobias Diebold. Having joined as Chief Commercial Officer in 2018, Tobias has seen first-hand the incredible expansion of the Group over recent years. From the outset, he made it his ambition to continue “driving growth and innovation that creates value for our clients, employees and all stakeholders.”
