Career

Wongrat Ratanaprayul is a partner and director of Tilleke & Gibbins’ Indonesia operations, based in Jakarta. She is recognized as a leading practitioner in Indonesia by IAM Patent 1000 and WTR 1000, and in 2023 she was named to Managing Intellectual Property’s list of the Top 250 Women in IP globally. She advises clients on all aspects of IP prosecution in Indonesia, as well as in multiple jurisdictions throughout Southeast Asia, to ensure efficient and effective IP portfolio management. Wongrat’s practice benefits from her exceptional breadth of expertise and her international reach.

Wongrat is a particularly adept patent practitioner, and is much sought-after in highly technical fields including biotechnology, pharmaceuticals, automotive, electronics, and computer-related technology. She regularly interviews inventors to derive information pertinent to drafting patent applications in life sciences and consumer products; provides opinions on freedom-to-operate analyses; routinely conducts patent and design searches; and provides clients with clear and practical patent portfolio management strategies to protect their interests.

Wongrat also oversees the firm’s regulatory affairs practice in Indonesia, serving clients in pharmaceuticals, food, cosmetics, and related industries with respect to product registration and compliance. In addition, she supervises the preparation of trademark applications, registrations, and renewals, and coordinates enforcement strategies to protect brand owners’ interests.

Prior to attending law school, Wongrat worked at Keck Graduate Institute, where she focused her research on proteomics. During her graduate study in biotechnology, she specialized in bioinformatics and annotated mouse genes present on pancreas cDNA.

Before moving to head up the firm’s Indonesia office, Wongrat worked as an attorney-at-law in the firm’s head office in Bangkok for several years. Wongrat is admitted to the bar in Connecticut and Massachusetts and is qualified as a Thai patent agent.
