기술보호 측면에서의 특허 명세서 작성 전략 -얼음 정수기 소송 사례를 중심으로-

For strong protection of technologies, all inventions should be included in the patent specification in detail. Attention should be paid to the preparation of specifications such as stating the claim in a manner that includes all major technical features. In particular, it is necessary to prepare a specification that can be amended in patent litigation, if necessary. In this study, a strategy for preparing a patent specification was proposed after reviewing amendment issues in the case of ice water purifiers, which were recently the subject of patent infringement litigation and patent invalidation. The amendments should be made so that the defendant's product does not deviate from the infringement while adding a minimum of features to the claim. Hence, the technical characteristics of the patent were classified and the amendment suitability was calculated. It was confirmed that it is important to include various technologies that are expected to be employed by competitors or that are likely to be adopted in the flow of technology development in preparation for subsequent patent disputes. In addition, the matter included in the drawings can be technically interpreted in various ways and used for amendments. Hence, it is necessary to prepare and attach a number of drawings.
