IP trials and litigation

Assignees of intellectual property rights such as patents, utility models, trademarks and designs have the right to issue letters of warning urging infringing parties to discontinue infringement and pay compensation for damages suffered.


 For patents, judging whether the protected rights are infringed requires a comparison of the patented claims against the infringing product in accordance with established infringement judgment criteria. This calls for the assistance of a patent attorney specializing in the technical field in question. Similarly, assistance from a patent attorney versed in the field is crucial for design and trademark cases.

In cases where issuance of a warning letter leads to
an outright dispute,

1) an invalidation trial or a trial to confirm the scope of patent rights may be held at the Intellectual Property Tribunal, or 2) an injunction claim against infringement or litigation for damages may be filed with the Seoul Central District Court, or a criminal procedure initiated by the Public Prosecutor.

1) usually falls within the scope of a patent attorney, while the procedures of 2) require the expertise of a lawyer. However, 1) and 2) are usually interconnected, and the effective resolution of an IP dispute normally involves collaboration between patent attorney and lawyer.
