This passion drives our efforts to help you safeguard your identity and originality. Ensuring that you maintain your lead on your competitors is of vital importance to us. How do we achieve this?

And by providing smart IT solutions. Our lead in IT allows us to provide customised solutions like no other.


When Marius Knijff and Miep Ras founded Knijff Trademark Attorneys in 1989, they made diversity and inclusivity key in the company’s operations. And more than three decades later, they still are.

The Knijff team is a tight-knit group of people from all sorts of backgrounds. Men and women are represented as follows among both our staff (29% vs 71%) and our partners (56% vs 44%). The company welcomes all skilled people regardless of gender, sexual orientation, background, religion or age. This ideal mix makes Knijff the strong and social company it is today.

Our recruitment, assessment and pay policies are based on an individual’s potential, inquisitive mind and willpower, creating a level playing field for all. We are all on the same team, a team that is all the stronger for its diversity. With so many different backgrounds and talents, Knijff offers an environment that is home to all and where all can flourish.

Knijff is proud of its staff and committed to offering them the very best working conditions. These include a choice of working from home or the office, the offer of inhouse training or personal courses, or customised solutions in case of illness for instance. Staff turnover is very low, and many people have been with Knijff for a long time. Some of our staff have even returned to Knijff after a stay elsewhere.


Sustainable environment

Sustainability is key for the society in which we live. Knijff takes its responsibility very seriously indeed. We contribute wherever and whenever we can. That includes enabling our staff to work from home. And with fewer cars on the road, nature benefits.

Waste reduction is another priority for us. Any waste is recycled or reused where possible. Since we introduced our digital office years ago, we have been able to drastically reduce our paper consumption.

Sustainability features in all of our decisions. Our vehicle fleet consists almost entirely of electrical cars and we recently doubled the number of charging stations at the office, now serving both staff and visitors.


We sponsor and fund social and ecological projects such as our pro bono services to Europa Nostra and our contributions to School at Sea. Our annual business gifts are carefully selected to ensure that proceeds from their sale go to charity or contribute to creating a sustainable society. Such examples are the WakaWaka Powerbank and the Chilly’s Bottle.

Knijff is committed to taking responsibility for its impact on man, the environment and society, both now and in the future.
