In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. DETAILED ACTION Examiner’s Notes Regarding Claim(s) 1-20: when reading the preamble in the context of the entire claim, the recitation of the preamble is not limiting because the body of the claim describes a complete invention and the language recited solely in the preamble does not provide any distinct definition of any of the claimed invention’s limitations.

However, Noe teach(es) an indicator (Fig. 3) including: a penetration prevention layer between medium layer and adhesion layer (Fig. 1: 150). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide Kim Jin Sik, with the teachings of Noe , for the purpose of preventing leaking of color (col. 5, lines 44-46). Regarding Claim(s) 10, Kim Jin Sik disclose(s) the indicator of Claim 9. Kim Jin Sik does not specifically disclose: a penetration prevention layer between medium layer and adhesion layer. However, Noe teach(es) an indicator (Fig. 3) including: a penetration prevention layer between medium layer and adhesion layer (Fig. 1: 150). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide Kim Jin Sik, with the teachings of Noe , for the purpose of preventing leaking of color (col. 5, lines 44-46). Regarding Claim(s) 19, Kim Jin Sik and Noe disclose(s) the indicator of Claim 4.
