Yuhan Patent & Trademark Law Firm

What Yuhan Patent & Trademark Law Firm does

Yuhan Patent & Trademark Law Firm (유한특허법률사무소) is a privately held South Korean intellectual property law firm headquartered in Hwaseong-si, southern Gyeonggi Province, owned and led by representative patent attorney Bu Yong-bin. The firm delivers a full lifecycle of IP services covering domestic and international filing, prosecution, opposition, trial, and patent-court litigation across the four foundational Korean IP categories — patents (특허권), utility models (실용신안권), trademarks (상표권), and designs (디자인권) — supplemented by licensing and technology transfer contracting, infringement analysis, warning-letter issuance, and IP trend/valuation consulting.

The firm's service delivery rests on a small bench of credentialed professionals: Korean patent attorneys (변리사) with diverse technical backgrounds in electronics, electrical engineering, semiconductors, computer engineering, IT/telecommunications, and mechanical systems; a cooperative patent attorney specialized in chemistry, materials, and energy; and an advisory lawyer providing general legal counsel. International reach is delivered through cooperative relationships with leading foreign IP law firms in the United States, Japan, China, and Europe, enabling multi-jurisdiction portfolio management without an in-house foreign desk. The firm operates as a single-location professional services practice with no disclosed parent company, venture backing, technology platform, or digital product.

The business model is fee-for-service professional billing on individual IP matters, acquired through direct consultation requests (phone and email) and in-person engagement at enterprise operational sites in southern Gyeonggi Province. There are no disclosed pricing schedules, no named customer accounts, and no public revenue figures; headcount disclosed in the input is approximately five professionals. Marketing is conducted through direct field engagement rather than digital or referral channels, with the firm's local presence and face-to-face service positioned as its primary differentiator against Seoul-centric IP practices.
