Firm overview

Empowering today shaping tomorrow.

From 1912 to future.

Founded in 1912 and managed by the 4th generation, Deris has established a boutique IP company providing services in all areas of intellectual property, on the strong foundation laid a century ago. It brings together the experience and culture of the past, the dynamics of the current period and expectations for the future. Today, Deris is one of the largest IP firms in Turkey and is internationally recognized among the top-tier legal service providers which plays a leading role in the development of IP landscape in Turkey.

ESG and diversity achievements

Our commitment to growth:

Investing in law students & interns

The aim of this approach is to prepare the lawyer candidates for business life in terms of professional and personal development, starting from law school. It includes a holistic approach to the goal, as it covers representation and networking skills as well as professional and personal development.

Leadership Development

Deris' observation in the leadership development programs for working lawyers was that universities do not develop competence in leadership, business perspective, business and people management. It is necessary to raise awareness of issues outside of professional knowledge as early as possible in order to mobilize the potential beyond which performance evaluation is not sufficient over the billed time alone. Both online internship and leadership awareness programs build a qualified pool for further stages at Deris.

Summer Internship

Deris, who receives many summer internship applications every year, can meet this demand by accepting a very limited number of students and without a special program for summer interns. With the pandemic period making distance education compulsory for students, the online summer internship project came to the fore as a result of the technical development of remote working methods.

Deris commits to UNGC

DERIS has joined the world's largest corporate sustainibility initiative "UNITED NATIONS GLOBAL COMPACT" which is a call to companies to align strategies and operations with universal principles of human rights, labour, environment and anti-corruption and take actions that advance societal goals. DERİS submits "CoP - Communication on Progress Report" every year open to public review.

Great for all

Deris was certified as a Great Place to Work for four consecutive years between 2019-2022. It has created and maintains its system to meet the "trust" model of this initiative. Tust model consists of five dimensions: credibility, respect, fairness, pride and camaraderie. Fairness assues that employees believe management practices and policies are fair; assesses the equity, impartiality, and justice employees experience in the workplace.
