There are several ways to save the cost of prosecuting a patent application and maintaining once it has been granted. And the key to considerably lowering the expense is to reduce the number of claims by incorporating multiple claims.
There are three ways in which reducing the number of claims can help save cost. First, an applicant can save cost during substantive examination, where the applicant must pay the total amount of US$37 multiplied by the number of claims in addition to the official fee of US$121. Second, once the patent has been granted, the applicant can reduce the amount of annuities, where they are charged based on the basic fee of US$36 multiplied by the number of granted claims in addition to the official fee of US$42. Lastly, the applicant can save the cost of translating the claims and the costs of prosecution and maintenance.
Much like EPO and JPO, multiple dependent sub-claims are permissible under Korean patent law. And for PCT route applications, it is recommendable to redraft claims to reduce the number of claims by using multiple dependent claims before starting the international phase.
But the Korean Rule of claim dependency is different from that of the EPO and the USPTO. According to the Korean Regulation, “No claim referring to two or more claims shall refer to another dependent claim to which two or more claims are referred.” This is to avoid high complexity caused by limitless dependent sub-claims. Therefore, the number of claims must be reduced within the limitation of the Rule in Korea.
In closing, an applicant can effectively reduce the number of claims without altering the scope of claims, and accordingly is able substantially to cut the cost of prosecuting an application and maintaining the granted patent.
