With over 100 seasoned attorneys and foreign legal counsels, Lee & Ko’s IP group delivers superior legal services focused on helping clients navigate the complex legal landscape while meeting their specialised requirements with practical and effective solutions. The IP group is dedicated to the protection, transfer, counselling and enforcement of IP rights.

Patent prosecution and patent office trials

The IP group assists clients in multiple industry sectors, including biotechnology, specialty chemicals, semiconductors, materials science, electronics, mechanical, pharmaceuticals, telecommunications and computer software. The IP group’s patent attorneys have significant experience litigating before the Korean Intellectual Property Office (KIPO) in invalidity and scope confirmation actions, and in carrying out freedom-to-operate analysis. The breadth and scope of their experience allow the IP group’s patent attorneys to create robust patents by evaluating the patent applications during preparation, filing and prosecution with a critical eye towards enforcement. The combined prosecution, transactional and litigation experience enables the IP group’s patent attorneys to ensure that clients develop valuable patent portfolios which offer the broadest protection while ensuring patent validity and enforceability.

Patent litigation, enforcement and dispute resolution

Success in any litigious matter can mean many things. However success is defined, the IP group produces results for the clients. The IP group understands that clients need a trial team with substantial technical and scientific knowledge, but also of substantive law and the rules and procedures governing legal proceedings. Many of the IP group’s litigators have strong technology-related backgrounds and skills which cover a wide range of technical fields. The IP group also includes litigators who were former judges specialising in IP law and IP cases while serving on the Supreme Court, Patent Court or Seoul High Court, as well as former examiners and administrative law judges from the KIPO. When criminal issues arise, the IP group works closely with attorneys, who formerly served as public prosecutors, at Lee & Ko’s white collar crime group. Complemented by insight received from senior lead litigators, many of whom have 20 to 30 years of trial experience, and seasoned foreign legal counsels, the IP group is in a unique position to create an effective trial team that can provide comprehensive legal services framed by technical, strategic, judicial, administrative and international perspectives.

Patent development and counselling

The IP group assists clients in developing and deploying a portfolio of strategic IP assets. Beyond the knowledge of IP matters and underlying technology, the IP group is fully aware of the fact that a key component to the success of any client includes the strategic use and licensing of its IP portfolio. The IP group has unrivalled experience in negotiating licensing, distribution and joint venture agreements covering all areas of intellectual property. Besides licence negotiation and drafting, the IP group provides counselling for clients on licensing strategies, IP-related competition law issues and strategic product development and distribution.

Patent strategy and management

A particular strength of the IP group lies in patent strategy and patent portfolio management. Strengthened by the broad scope of its scientific and technological expertise, the IP group works with clients to formulate patent strategies – relating to patent prosecution, enforcement, transaction and litigation – that are in line with clients’ business objectives, while providing additional services that include risk assessment, patent due diligence, technology mapping and regulatory guidance.
