Office Action

§102 §103 §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 . Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(1) because they are unclear/poor quality with low resolution and ambiguous lines. Additionally, the drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they include the following reference character “90” in Figs. 2- 6 but is not mentioned in the description. Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the specification to add the reference character(s) in the description in compliance with 37 CFR 1.121(b) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. In addition to Replacement Sheets containing the corrected drawing figure(s), applicant is required to submit a marked-up copy of each Replacement Sheet including annotations indicating the changes made to the previous version. The marked-up copy must be clearly labeled as “Annotated Sheets” and must be presented in the amendment or remarks section that explains the change(s) to the drawings. See 37 CFR 1.121(d)(1). Failure to timely submit the proposed drawing and marked-up copy will result in the abandonment of the application. Claim Objections Claims 1 and 19 are objected to because of the following informalities: typographical errors. Claims 1 and 19 recite “abutting against the barrel of the syringe; and when the…” Claim 19 additionally recites “for placing the syringe; and the pushing…” Examiner recommends adding a new line for each additional limitation listed after “; and”. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 19 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 19 recites “a pump body” on line 4 rendering the claim indefinite because it is unclear whether it is referring to the same pump body introduced in the first limitation on line 2. Examiner recommends amending claim to recite “the pump body”. Appropriate action is required. 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 first driving mechanism… for driving the…” in claims 1 and 19. 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 § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 2-4 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Wei in view of Liu et al. (EP 4059546 A1, herein, Liu). Regarding claim 2, Wei teaches the syringe fixation device according to claim 1, as recited above. Wei does not appear to expressly teach wherein the transmission rod is provided with a transmission thread on an outer side of the transmission rod close to the second end thereof; and the first driving mechanism comprises a driving motor and a transmission nut, the driving motor is mounted on the pump body, an output shaft of the driving motor is connected to the transmission nut so as to drive the transmission nut to rotate, and the transmission nut is sleeved on the transmission thread. However, Liu teaches wherein the transmission rod (screw rod 141 – Fig.4) is provided with a transmission thread (under broadest reasonable interpretation, the examiner interprets a screw rod as a metal bar with continuous helical threading hence teaching that the transmission rod is threaded) on an outer side of the transmission rod close to the second end thereof; and the first driving mechanism (drive mechanism 15 – Fig.3) comprises a driving motor (“the drive mechanism 15 may be a motor with a drive function”, see para [0034]) and a transmission nut (screw nut 142 – Fig.4), the driving motor is mounted on the pump body (“the pump body device 10 includes a base body 11… a transmission assembly 14 and a drive mechanism 15”, see para [0012]), an output shaft (output shaft 151 – Fig.16) of the driving motor is connected to the transmission nut so as to drive the transmission nut to rotate (“though driving of the drive mechanism 15, the rotary motion of the screw rod 141 can be converted into the linear motion of the screw nut 142”, see para [0035]), and the transmission nut is sleeved on the transmission thread (“a screw nut 142 which is threaded with the screw rod 141”, see para [0035]). It would have been obvious to one of ordinary skill within the art before the effective filing date of the invention to modify the transmission rod as disclosed by Wei in view of Wei to include a transmission nut and output shaft as taught by Liu in order to “to provide an injection pump with a relatively compact structure” (Liu, see para [0004]). Regarding claim 3, Wei teaches the syringe fixation device according to claim 2, as recited above. Wei does not appear to expressly teach wherein the first driving mechanism further comprises a transmission assembly, the transmission assembly being connected to the driving motor and the transmission nut. Liu teaches wherein the first driving mechanism (driving mechanism 15 – Fig.2) further comprises a transmission assembly (transmission assembly 14 – Fig.2), the transmission assembly being connected to the driving motor and the transmission nut (“the transmission assembly 14 of this embodiment also includes a screw nut 142 which is threaded with the screw rod 141… though driving of the drive mechanism 15, the rotary motion of the screw rod 141 can be converted into the linear motion”, see para [0035], Fig.2). It would have been obvious to one of ordinary skill within the art before the effective filing date of the invention to modify the first driving mechanism as disclosed by Wei in view of Wei to include a transmission assembly as taught by Liu in order to “to provide an injection pump with a relatively compact structure” (Liu, see para [0004]). Regarding claim 4, Wei teaches the syringe fixation device according to claim 3, as recited above. Wei does not appear to expressly teach wherein the transmission nut is connected to the pump body and is rotatable about an axis of the transmission nut, transmission teeth are provided on an outer side of the transmission nut; and the transmission assembly comprises at least one transmission gear, the transmission gear is sleeved on the output shaft of the driving motor and meshes with the transmission teeth. Liu teaches wherein the transmission nut (screw nut 142 – Fig.2) is connected to the pump body and is rotatable about an axis of the transmission nut, transmission teeth are provided on an outer side of the transmission nut (“the screw nut 142 has a spiral tooth 142a”, see para [0035]); and the transmission assembly (transmission assembly 14 – Fig.2) comprises at least one transmission gear (“the transmission assembly 14 of this embodiment also includes a gear mechanism 143”, see para [0062]), the transmission gear is sleeved on the output shaft (output shaft 151 – Fig.16) of the driving motor and meshes with the transmission teeth (“The output shaft of the drive mechanism 15 is in drive connection with the primary gear 1432'”, see para [0063], Fig.12). It would have been obvious to one of ordinary skill within the art before the effective filing date of the invention to modify the syringe fixation device as disclosed by Wei in view of Wei to include a transmission teeth, nut and gear as taught by Liu in order to “ensure that the torque output of the drive mechanism is amplified, but also ensure that the rotation speed of the screw rod meets the requirements” (Liu, see para [0064]). Regarding claim 17, Wei teaches the syringe fixation device according to claim 1, recited above. Wei does not appear to expressly teach the syringe fixation device further comprising a pushing member provided to apply pressure to the plunger, said pushing member being actuated by a pump via a pushing rod; a pressure sensor in contact with an end portion of the plunger and being provided to measure a pressure value between the pushing member and thereby determine a pressure-dependent state of the plunger. Lui teaches a syringe fixation device further comprising a pushing member (push-pull box assembly 20 – Fig.12) provided to apply pressure to the plunger, said pushing member being actuated by a pump via a pushing rod (connection shaft 13 – Fig.12); a pressure sensor in contact with an end portion of the plunger and being provided to measure a pressure value between the pushing member and thereby determine a pressure-dependent state of the plunger (“the pressure sensor assembly 27, which is arranged inside the box 21m can detect the pressure inside the barrel of the syringe 200 and transmit the detection signal to the main board 80”, see para [0081]). It would have been obvious to one of ordinary skill within the art before the effective filing date of the invention to modify the syringe fixation device to further comprise a pressure sensor as taught by Liu in order to “effectively improving the structural compactness of the internal parts of the push-pull box assembly 20 and reducing the overall volume of the push-pull box assembly 20” (Liu, see para [0067]). Allowable Subject Matter Claims 10-15 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: Claims 10-15 in this application have been indicated as allowable subject matter because the prior art of record fails to disclose or make obvious the claimed invention including the following features: “wherein the guide groove comprises a linear groove section and a spiral groove section that are connected to each other, wherein an extension direction of the linear groove section is parallel to an axis of the guide ring, the linear groove section has a guide inlet formed at the second end of the cylindrical body, the spiral groove section is closer to the fixing block than the linear groove section, and an extension direction of the spiral groove section surrounds the axis of the guide ring”. “wherein a mounting groove is provided in a side surface of the cylindrical body close to the second end thereof and has a mounting opening formed at the second end of the cylindrical body; the second end of the cylindrical body is provided with a connecting cylinder, said connecting cylinder having a smaller radius than the cylindrical body; the syringe fixation device further includes a first mounting frame, the first mounting frame comprising a first mounting ring and a first connecting arm, said first mounting ring being sleeved on the connecting cylinder; the first connecting arm is arranged in an axial direction of the first mounting ring and is connected to the first mounting ring, and the first connecting arm is mounted in the mounting groove; and the guide protrusion is provided on a side of the first connecting arm facing away from the mounting groove”. Claims 12-15 are allowable by virtue of dependency on claim 11. The combination of the claimed limitations are novel and found to be allowable over the prior art. The cited references taken singly or in combination do not anticipate or make obvious the Applicant' s claimed invention.
