§102 §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 Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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(s) 1-4, 6-10, 12-15, 17-21, and 23 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2019/0216380 A1 to Isosevic et al. (“Isosevic”). Regarding Claim 1, Isosevic discloses a device for obtaining a blood sample (Abstract), the device comprising: a holder for receiving a sample source (holder 12 receives a finger that supplies a blood sample, Para. [0060]; Fig. 10), the holder having an actuation portion (actuation portion 24, Fig. 2) and a port (port 26, Fig. 2); a container engagement portion connected to the holder (container engagement portion 72 connects to holder 12 via port 26, Fig. 10); and a collection container removably connectable to the container engagement portion (blood collector portion 74 connects to container engagement portion 72, Fig. 10; blood collector portion 74 can be removed and a cap 76 placed on it, Para. [0080]; Fig. 10), the container defining a collection cavity (blood collector portion 74 contains collection cavity 70, Fig. 10), wherein the actuation portion comprises at least two wings that are angled relative to a patient's finger held in the holder (actuation portion 24 has wings 38 at an angle from finger 19 in holder 12, Fig. 23) to create a pressure gradient towards a fingertip of the patient's finger (actuation portion 24 applies pressure to a portion of finger 19, Para. [0065]; Fig. 23). Regarding claim 2, Isosevic discloses the device of claim 1, wherein the at least two wings are positioned on the holder at a position proximal of a fingernail of the patient's finger and distal from a first knuckle of the patient's finger (wings 38 are positioned proximal the tip of a fingernail and distal a knuckle, Fig. 23). Regarding Claim 3, Isosevic discloses the device of claim 1, wherein each of the at least two wings includes a touch pad that ensures a user squeezes the wings at a desired location (touch pad is space of wing 38 above ridge closest to port 26, the ridge is functionally capable of using friction to keep a user's finger or grip on the touch pad, Fig. 14). Regarding claim 4, Isosevic discloses the device of claim 1, wherein the holder further comprises a stability extension portion provided on a proximal end of the holder (stability extension portion 40 on a proximal end of holder 12, Fig. 10). Regarding claim 6, Isosevic discloses the device of claim 1, wherein at least one wing of the at least two wings includes an anti-touch protrusion that extends outwardly from an outer surface of the wings (wing 38 includes a ridge on its outer surface closest to port 26, Fig. 14). Regarding claim 7, Isosevic discloses the device of claim 6, wherein the anti-touch protrusion is positioned beneath a touch pad of the at least one wing to ensure a user grips the at least one wing at the touch pad and not beneath the touch pad (touch pad is space of wing 38 above ridge closest to port 26, the ridge is functionally capable of preventing a user's finger or grip from slipping beneath the touch pad, Fig. 14). Regarding claim 8, Isosevic discloses the device of claim 1, wherein a proximal end of the holder includes a flared edge to receive the patient's finger (proximal-most edge of stability extension portion 40 flares upward in a circular shape and receives finger 19, Fig. 27). Regarding claim 9, Isosevic discloses the device of claim 1, wherein a transition portion is positioned between the holder and the container engagement portion to receive at least a portion of the patient's finger during use of the device (finger end guard 30 between the majority of holder 12 and container engagement portion 72, Fig. 10; finger end guard 30 receives fingertip, Fig. 23). Regarding claim 10, Isosevic discloses the device of claim 1, wherein a distal end of the holder includes a curved edge to receive a patient's fingertip while allowing the patient's fingernail to extend past the distal end of the holder (curved finger end guard 30 receives fingertip but is short enough to allow a long fingernail to extend past finger end guard 30, Figs. 10 and 23). Regarding claim 12, Isosevic discloses a device for obtaining a blood sample (Abstract), the device comprising: a holder for receiving a sample source (holder 12 receives a finger that supplies a blood sample, Para. [0060]; Fig. 10), the holder having an actuation portion (actuation portion 24, Fig. 2) and a port (port 26, Fig. 2); and a container engagement portion connected to the holder (container engagement portion 72 connects to holder 12 via port 26, Fig. 10); wherein the actuation portion comprises at least two wings that are angled relative to a patient's finger held in the holder (actuation portion 24 has wings 38 at an angle from finger 19 in holder 12, Fig. 23) to create a pressure gradient towards a fingertip of the patient's finger (actuation portion 24 applies pressure to a portion of finger 19, Para. [0065]; Fig. 23). Regarding claim 13, Isosevic discloses the device of claim 12, wherein the at least two wings are positioned on the holder at a position proximal of a fingernail of the patient's finger and distal from a first knuckle of the patient's finger (wings 38 are positioned proximal the tip of a fingernail and distal a knuckle, Fig. 23).

[0065]; Fig. 23). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 5 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Isosevic in view of US 7,591,791 B2 to Keren. Regarding claim 5, Isosevic discloses the device of claim 4. Isosevic fails to explicitly disclose wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder. Keren is in the field of blood tests (Abstract) and teaches wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder (distal end of cavity 16 has rubber flange 18 which enhances gripping of the finger and keeps the finger in place, Col. 4, Lns. 31-33; Fig. 3). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Isosevic with wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder of Keren. The motivation being to stabilize the finger and thus properly draw a blood sample from a safe location on the finger. Regarding Claim 16, Isosevic discloses the device of claim 15. Isosevic fails to explicitly disclose wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder. Keren is in the field of blood tests (Abstract) and teaches wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder (distal end of cavity 16 has rubber flange 18 which enhances gripping of the finger and keeps the finger in place, Col. 4, Lns. 31-33; Fig. 3). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Isosevic with wherein the stability extension portion includes at least one retention bump that extends inwardly from an inner surface of the stability extension portion to contact the patient's finger held in the holder of Keren. The motivation being to stabilize the finger and thus properly draw a blood sample from a safe location on the finger. Claim(s) 11 and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Isosevic in view of US 8,333,715 B1 to Alferness. Regarding claim 11, Isosevic discloses the device of claim 1. Isosevic fails to explicitly disclose wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion. Alferness is in the field of blood glucose sampling (Abstract) and teaches wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion (a protruding on the outer grip of blood glucose sampling device 56 into the test finger 59 specifically impedes venous return but still allowing arterial flow, Col. 7, Lns. 43-59; Fig. 5). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Isosevic with wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion of Alferness. The motivation being to reduce bleeding while focusing on drawing blood selectively from only the venous or arterial route. Regarding claim 22, Isosevic discloses the device of claim 12. Isosevic fails to explicitly disclose wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion. Alferness is in the field of blood glucose sampling (Abstract) and teaches wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion (a protruding on the outer grip of blood glucose sampling device 56 into the test finger 59 specifically impedes venous return but still allowing arterial flow, Col. 7, Lns. 43-59; Fig. 5). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Isosevic with wherein the holder includes a finger receiving portion that includes at least one bulge on an outer surface of the finger receiving portion to prevent pressure on an arterial blood supply of the patient's finger held in the finger receiving portion of Alferness. The motivation being to reduce bleeding while focusing on drawing blood selectively from only the venous or arterial route.
