2. The judgment patent is a right granted through the examination and registration of the Korean Intellectual Property Office, which is a State agency, and the Patent Act provides that a patent may be invalidated through a separate procedure for the invalidation trial of a patent established in a case where a certain reason exists. Thus, barring special circumstances, a patentee is generally entitled to believe that his/her right is lawful and effective and exercise it (see Supreme Court Decision 2009Do4949, Oct. 28, 2010). Article 126(1) of the Patent Act provides that a patentee may claim the prohibition or prevention against a person who infringes or is likely to infringe his/her right, and Article 127 provides that a patentee shall transfer or transfer the patented goods or methods.
