Who We Are

Devin Law & IP

A Proven Legal Blueprint to Secure What You've Built.

Devin Law & IP is a boutique law firm with over 15 years of combined experience from its founders and partners. The firm operates on principles of transparency, integrity, and shared values, and delivers sustainable legal solutions through dedicated practice groups.

We serve diverse international clients by forming specialized teams with sector expertise. Long-term client relationships, diversity, continuous education and professional development are our core institutional values.

Founded on professionalism, transparency and long-term value creation, the firm combines sector expertise with strategic legal insight — providing clear, practical and result-oriented solutions for businesses and individuals.

Alongside its Istanbul headquarters, the firm manages trademark and patent portfolios across multiple jurisdictions through its attorneyship practice — handling filings, oppositions, renewals and enforcement before TÜRKPATENT, EUIPO and WIPO on behalf of local and international rights holders.

This dual structure — Legal Services on one side and Trademark / Patent Attorneyship Services on the other — allows the firm to combine contentious litigation strength with disciplined portfolio administration, so that every matter is handled by a team specialised in its own field.
