Office Action

§DP
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 . DETAILED ACTION Priority Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement            The references cited on Form PTO 1449 have been considered. Specification The specification has been checked to the extent necessary to determine the presence of all possible minor errors. However, the applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the "right to exclude" granted by a patent and to prevent possible harassment by multiple assignees. See In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and, In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent is shown to be commonly owned with this application. See 37 CFR 1.130(b). Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). * Claim 8 is rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1 and 6 of U.S. Patent No. 12,285,951. Although the conflicting claims are not identical, they are not patentably distinct from each other because the patent claims fully encompass applicant's instantly claimed invention. Citation of Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. These prior art references (US Pat. 5,392,063) cited in the PTO 892 form show an ink cartridge which is deemed to be relevant to the present invention. These references should be reviewed. Allowable Subject Matter Claims 1-6 are allowed because none of the prior art references of record teaches a supply unit in which a liquid container including a coupling portion is detachably mounted, the supply unit comprising an air damper configured to absorb energy, when engagement of the engaging portion with the liquid container is released in the combination as claimed. Claim 7 is allowed because none of the prior art references of record teaches a liquid container detachably mounted in a supply unit, the supply unit including a liquid introducing portion configured to introduce a liquid, a pressing member configured to generate a pressing force, an engaging portion, and an air damper, the liquid container comprising: a receiving recessed portion configured to store at least a part of the air damper, the air damper being configured to reduce a moving speed of the liquid container moving in the uncoupling direction in the combination as claimed.
