1. The decision made by the Intellectual Property Tribunal on May 29, 2018 by the Intellectual Property Tribunal on the case No. 2017Da2550 is revoked.

2. The costs of lawsuit shall be.

(c) shall be.

) It is reasonable to see that ordinary technicians are not written to the extent that they can be easily carried out. (a) In civil engineering or construction fields, aggregate (OD: OV Dry terms terms (AD) dry condition (AD) means drying sand from 105°C for more than 24 hours, depending on the status of brine (including water);

The dry condition (AD: Air Dry, SSD (SD) table (SD) table table inside Surface Dry (SDD) refers to the condition of construction inside sand surf, while the surface is dried. This is obtained by building only a sand surface after 24 hours after sand was stored in the water.

The term "absorbing rate" is defined as "(SD) weight - dried (OD) weight 】 100/out (OD) weight" in the proportion of the water content contained in the aggregate in the condition of scalking (D) compared to the dry condition. The term "water rate" is defined as "(s sand content - dried (OD) weight) *100/out (OD) weight" in the proportion of water content contained in the sand compared to the dry condition. In general, it is reasonable to see that sand is used as a scale such as absorption rate, absorption rate, etc. in the abnormal condition of sand ingredients, and that it is reasonable to see that it is under the premise of the abnormal status of composition in the determination of ordinary ingredients. In full view of the above, it is reasonable to see that sand is used as a specific absorption rate, such as absorption rate, and that it is used as a specific absorption rate in the case of aggregate 257/27/200 or less in the case of soil absorption rate (OD) in the shape of aggregate.

(B) In light of the fact that the weight of sand, which the Defendant submitted, was about 3.6% in the evidence No. 2, it appears that the provision of the absorption rate of natural aggregate in the KS Standard (KSF 2527) is below 3.0% in the natural aggregate absorption rate, would mean a suled sand. (B) Furthermore, in the description of the invention of this case, GRC.
