Allowable Subject Matter Claims 3-10 and 17-18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 3, the prior art of record, taken alone or in combination, fails to teach or fairly suggest, in combining with other limitations recited in claim 1 and a combination of limitations that wherein the ground flexible printed circuit board includes: a base film; a ground pad disposed at one end of the base film; an opening spaced apart from the ground pad and extending through the base film; a terminal extending from the base film and located in the opening, wherein the terminal includes a plurality of metal terminal patterns on a rear surface of the terminal; and a plurality of resistance patterns located on one side of the opening and disposed on the base film. None of the reference art of record discloses or renders obvious such a combination. Regarding claim 17, the prior art of record, taken alone or in combination, fails to teach or fairly suggest, in combining with other limitations recited in claim 16 and a combination of limitations that wherein the ground flexible printed circuit board includes: a base film; a ground pad disposed on the base film; an opening extending through the base film; a terminal extending from the base film and located in the opening; and a plurality of resistance patterns disposed on the base film. None of the reference art of record discloses or renders obvious such a combination. Claims 4-10 are objected as being dependent on claim 3. Claim 18 is objected as being dependent on claim 17. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Yeon (US 20050078459) teaches a display device comprising a flexible printed circuit board (200) that is disposed at one end of the display panel (110); the flexible printed circuit board comprises at least one hole (242).
