facilities used for the act of infringement, or other measures necessary to prevent the infringement.  
Article 127 (Acts Deemed to be Infringement)

IP/N/1/KOR/P/5 
Page 75transfer of in fringing articles, the amount of losses may be calculated by multiplying the number of 
transferred articles by the profit per unit of the articles that the patentee or exclusive licensee might 
have sold in the absence of said infringement. In such cases, the compensation may not exceed an 
amount calculated by multiplying the estimated profit per unit by the amount obtained by subtracting 
the number of articles actually sold from the number of products that the patentee or exclusive 
licensee could have produced: Provided, That where the patentee or exclusive licensee was unable 
to sell his/her product for reasons, other than infringement, a sum calculated according to the 
number of articles subject to the said circumstances shall be deducted. <Newly Inserted by Act No.
