Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a transfer film support unit in claim 1, a first stretching unit in claim 1, a second stretching unit in claim 1, a fixing unit in claim 2, a first vertical driving unit in claim 2, a second vertical driving unit in claim 2, an auxiliary support part in claim 3, a third vertical driving unit in claim 3, a main support part in claim 8, a fourth vertical driving unit in claim 8, a transfer film support unit in claim 11, a first stretching unit in claim 11, a second stretching unit in claim 11, a third stretching unit in claim 11, a fixing unit in claim 12, a first vertical driving unit in claim 12, a second vertical driving unit in claim 12, an auxiliary support part in claim 14, a third vertical driving unit in claim 14, a main support part in claim 15, a fourth vertical driving unit in claim 15, and a fifth vertical driving unit in claim 16. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura [US2008/0190902] in view of Shimizu [KR2012-0094428, machine translation provided]. Nakamura disclose a transfer film stretching device comprising: a transfer film support unit (371) having a top surface configured to receive a transfer film (Figures 9-11; paragraph 0065), it is noted the transfer film is considered to be the material worked upon and the device of Nakamura would be capable of working upon a transfer film as disclosed in the claim, a first stretching unit (36) outside the transfer film support unit (371) and configured to move in one direction or another direction of a third direction while fixing an outer edge of the transfer film to stretch a width of the transfer film in an outer circumferential direction (Figures 9-11; paragraph 0064). Nakamura discloses the first stretching unit includes a holding means and clamp, but fails to disclose a second stretching unit between the first stretching unit and the transfer film support unit. Shimizu discloses a dicing tape stretching device comprising a support unit (table 10), a frame fixing unit (18) and frame (F) for holding an outer edge of the tape, wherein a second stretching unit (lifting ring 12) between the first stretching unit (18) and the transfer film support unit (10) (Figures 4-6; see Brief Description of Drawings from machine translation). It would have been obvious to one of ordinary skill in the art at the time of invention to modify the device of Nakamura by including a second stretching unit as taught by Shimizu in order to provide a greater range and control over the stretching force applied to the film. With respect to claim 7, Nakamura discloses the first stretching unit has a cylindrical columnal shape having an opening (Figure 9). Shimizu discloses the second stretching unit (16) is in the opening of the first stretching unit (F), and the transfer film support unit (10) is in the opening of the second stretching unit (Figure 1). Allowable Subject Matter Claims 2-6 and 8-10 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. Claims 11-20 are allowed.
