Office Action

§112
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 . Response to Request for Reconsideration Withdrawn Rejections The 35 U.S.C. 112(b) rejections of claims 1-9, 11-19, are withdrawn due to Applicant’s arguments in the response filed on April 1, 2026. The 35 U.S.C. 103 rejections of claims 1-19 over Ishikawa as the primary reference, are withdrawn due to Applicant’s arguments in the response filed on April 1, 2026. New Rejection Claim Rejections - 35 USC § 112 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1-19 are rejected under 35 U.S.C. 112(b) as failing to particularly point out and distinctly claim the subject matter which the inventor or a joint invention regards as the invention. It is unclear in claim 1, whether the ink is in a cured state, and the conditions in which the ink is cured in order to obtain the tensile strength of 40-70 MPa and impact resistance of 1-4 ft.lb/in. Claims 2-19 depend on and include all the subject matter of claim 1, but fail to provide any solutions to the indefinite issue described above. Clarifications and amendment with relevant citation(s) from the specification are required. Any inquiry concerning this communication should be directed to Sow-Fun Hon whose telephone number is (571)272-1492.
