3. The defendant's argument regarding the defendant's assertion is without merit since the defendant's defect exists in the RSV test key among the goods supplied by the plaintiff, and the damage occurred to the defendant. Thus, the plaintiff's unpaid claim for the price of goods and the defendant's claim for compensation for damage should be offset on an equal amount, or there is no evidence to prove that there is a defect in the above test key supplied by the plaintiff. Thus, the above argument by the defendant is without merit.

4. In conclusion, the plaintiff's claim of this case is justified and it is so decided as per Disposition.
