The judgment below is reversed and the case is remanded to Seoul High Court.

The grounds of appeal are examined.

1.

Thus, the Claim No. 4 invention of this case should be deemed to have been registered by the specification after the correction was made pursuant to Article 136(8) of the Patent Act.

Therefore, the judgment of the court below that deliberated and judged the validity of the Plaintiff’s claim based on the patent right of the instant Claim No. 4 prior to its correction cannot be maintained any longer due to the grounds for retrial under Article 451(1)8 of the Civil Procedure Act.

2.

It is so decided as per Disposition by the assent of all participating Justices on the bench.
