“Reliable, responsive, and capable of providing full-IP services with practical solutions at reasonable costs”, general legal practice Bross & Partners is gaining momentum in the Vietnamese IP sphere. With a newly opened office in Danang — alongside its Ho Chi Minh City and Hanoi outposts — it is now excellently positioned to handle the increasing demand across the whole country. Founder Le Quang Vinh leads the compact squad to represent major domestic and foreign players: he has recently filed patent applications for Korean firms Seoul Semiconductor and Seoul Viosys and undertaken extensive prosecution work on behalf of a top European technology company. On the litigation front, Vinh is defending a VR500 enterprise, PCC1, in an infringement case regarding aluminium cables. One source enthuses: “Le Quang Vinh has rich experience in all IP fields and is an insightful problem solver.”
