Jakarta, Indonesia.

Assegaf Hamzah & Partners (AHP), one of the largest firms in Indonesia and a member of Singaporean Big Four firm Rajah & Tann’s regional network, has expanded its intellectual property practice.

AHP will acquire local IP boutique Dewi Soeharto Law Partnership (DSLP) on June 5. The four-lawyer boutique has focused its practice on advising blue-chip companies and social institutions on copyrights, trademarks and patents matters since 2007, according to a Rajah & Tann Asia statement. AHP was founded in 2001 and has approximately 130 lawyers, 22 of whom are partners.

DSLP founder and sole partner Dewi Soeharto will co-lead AHP’s IP practice together with AHP co-founder Chandra Hamzah, who currently heads the IP practice.

AHP is expanding its IP practice at a time when Indonesia has been building a more effective foundation for IP policy, according to the U.S. Chamber of Commerce’s latest international IP index, which ranks 50 economies based on 40 indicators across eight IP-related categories, such as patents, trademarks and enforcement.

Indonesia’s overall score this year was 12.14 out of 40, up from 9.64 out of 35 last year. However, the country is still ranked near the bottom—at No. 43 out of 50 economies—and is the lowest ranked Southeast Asian nation in the index.

Indonesia improved in the copyrights, related rights and limitations category, though its score worsened in the patents, related rights and limitations and enforcement categories, according to the index.
