A&CO Law Office, established in 2013, is a mid-sized full-service law firm with a strong focus on Intellectual Property. Since its establishment, the firm has been committed to providing practical, commercially driven, and high-quality legal services to both domestic and international clients across a wide range of industries.
Our Intellectual Property practice has long been one of the firm's core strengths and is widely recognized for its strategic, solution-oriented approach. The team advises clients on a broad spectrum of IP matters, including trademark prosecution, enforcement, litigation, licensing, portfolio management, anti-counterfeiting measures, and general advisory work. We regularly assist multinational corporations, local enterprises, and emerging businesses in protecting, managing, and enforcing their intellectual property rights in Indonesia.
What distinguishes our practice is our ability to combine in-depth legal expertise with a practical understanding of our clients' commercial objectives. We recognize that every matter presents unique legal and business considerations, and therefore each case is approached through careful analysis, strategic planning, and close collaboration among our practitioners to develop solutions that are tailored to our clients' specific needs.
A key strength of the practice lies in the extensive experience and deep knowledge of our partners, who have been actively involved in the Intellectual Property field for many years. Several of our partners also play active roles in leading professional organizations, including serving as a Member of the Anti-Counterfeiting Committee of the APAA Indonesia Group and as Vice Coordinator for the Special Capital Region of Jakarta at the Indonesian Intellectual Property Attorneys Association (Asosiasi Konsultan Hak Kekayaan Intelektual Indonesia – AKHKI). Their involvement enables the firm to remain well informed of legislative developments, enforcement trends, and best practices within Indonesia's evolving intellectual property landscape.
Over the years, the firm has successfully represented clients in numerous contentious and non-contentious intellectual property matters, consistently delivering commercially sound and favorable outcomes. This track record reflects not only the firm's legal capabilities but also its commitment to responsiveness, teamwork, and long-term client relationships when handling complex and commercially sensitive matters.
The firm continues to strengthen its Intellectual Property practice by investing in continuous professional development, adapting to developments in technology and digital business, and expanding its capabilities in cross-border and commercially driven IP matters. We also place significant emphasis on efficiency and client service by leveraging technology, streamlining internal processes,
and maintaining effective coordination across our team to deliver timely, practical, and cost-effective legal support.
