I. Types of Trials in Intellectual Tribunal of Korean Industrial Proprty Office

1. Trial for confirmation of the scope of a patent right

This trial can be initiated only by an interested party. In case of infringement by a third party, a controversy arises as to whether there actually exists an infringement or not. In such case, a patentee or an interested party can demand a Trial for Confirmation of the Scope of a Patent Right with the KIPO in order to receive a judgment officially determining whether or not the subject patent right may cover technically the article manufactured, sold and/or used by an infringer.

2. Trial for invalidation of a patent right

If a patent falls into one of the following particulars, the patent can be invalidated by a Trial:

a) In case that a patent has been granted to a person who has no right to own and enjoy the patent right.

b) In case that a patent has been granted for an invention that is not a new industrial one.

c) In case that a patent has been granted for an invention known and used publicly prior to the filing of the patent application.

e) In case that a patent has been granted for an invention published on the publication circulated in Korea or in a foreign country prior to the filing of the patent application.


f) In case that a patent has been granted for an invention which was filed later than another prior application covering the same invention.

g) In case that a patent has been granted for an invention which can not be carried in business.

The Trial for invalidation of Patent must be demanded by an interested party only or a KIPO Examiner in charge. If a patent is invalidated by a judgment, it is recognized that the patent right did not exist from the beginning.

3. Trial for correction

a) To narrow the scope of the claims,

b) To correct the clerical errors, or

c) To clarify the ambiguous description.

However, it is impossible to broaden the scope of the claims and the amendment must be one which would be acceptable at the time when the patent was granted.

4. Trial for invalidation of correction

If Correction has been made beyond the scope the above trail for correction, an interested party or an Examiner can initiate a trial for the invalidation of correction.
