Withdrawn Objections & Rejections
The objections and rejections presented herein represent the full set of objections and rejections currently pending in the application. Any objections or rejections not specifically reiterated are hereby withdrawn.
The rejection of claims 35-46, 48-53, and 89-91 under 35 U.S.C. 102(a)(1) or 35 U.S.C. 102(a)(2) as being anticipated by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited) as evidenced by Oxford Languages (retrieved from internet 03/31/2025, previously cited), Blood Bank Guy (retrieved from internet 03/31/2025, previously cited), Severinghaus (Journal of Applied Physiology, 46(3): 599-602, 1979, previously cited), Sharma et al. (Asian J Tranf Sci, 2010, previously cited) and Meyer et al. (Blood Complications, 2011) is withdrawn to address the claim amendments.
The rejection of claim 92 is rejected under 35 U.S.C. 103 as being unpatentable over Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”) in view of view of Masse (Transfus Clin Biol, 2001), as evidenced by Oxford Languages (retrieved from internet 03/31/2025), Blood Bank Guy (retrieved from internet 03/31/2025), Severinghaus (Journal of Applied Physiology, 46(3): 599-602, 1979, previously cited), and Meyer et al. (Blood Complications, 2011) is withdrawn to address the claim amendments.
Claim Interpretation
Claim 1 recites the term “stored” as in a “stored oxygen and carbon dioxide reduced leukoreduced whole blood composition.”
The specification does not define this term.
As understood in the art, as defined by Oxford Languages (retrieved from internet 03/31/2025, previously cited), the verb “store” means “[To] keep or accumulate (something) for future use.”
Thus, giving the term its broadest reasonable interpretation in view of the disclosure and the art, the “stored” blood composition has been interpreted as any oxygen and carbon dioxide reduced leukoreduced whole blood that has been kept or accumulated for future use.
It is noted that the timing of the storage is unlimited in the claims and may be stored for any amount of time.
Claim 1 also recites the term “leukoreduced” which is not specifically defined in the specification.
As evidenced by Blood Bank Guy (retrieved from internet 03/31/2025, previously cited), as understood in the art, leukocyte reduction (leukoreduction), is the process of removing white blood cells from a blood product prior to transfusion.
Claim Rejections - 35 USC § 112(b)
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.
Claims 49-50 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 49 contains the trademark/trade name “TEG”. Where a trademark or trade name is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade name is used to identify/describe a parameter in a specific viscoelastic hemostatic assay and, accordingly, the identification/description is indefinite.
Referring to instances of TEG in the claim as “thromboelastography” (e.g., “thromboelastography angle” in line 5, etc.) would be ameliorative.
Claim 50 is rejected under 35 USC 112(b) for its dependence on claim 49.
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 35-40, 53, and 89-91 are rejected under 35 U.S.C. 102(a)(1) or 35 U.S.C. 102(a)(2) as being anticipated by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited) as evidenced by Severinghaus (Journal of Applied Physiology, 46(3): 599-602, 1979, previously cited).
Claims 35, 41-46, and 48-52 are rejected under 35 U.S.C. 102(a)(1) or 35 U.S.C. 102(a)(2) as being anticipated by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited) as evidenced by Severinghaus (Journal of Applied Physiology, 46(3): 599-602, 1979, previously cited) and Sharma et al. (Asian J Tranf Sci, 2010, previously cited).
In regards to claims 35-39, and 89-90, as newly amended, the claim is drawn to a “stored oxygen and carbon dioxide reduced leukoreduced whole blood composition for transfusion to a trauma patient in need of multiple transfusion.”
While the claims are drawn to a product (a composition), storing that product is a process step. Thus, claim 35 is a product-by-process claim.
In regards to product-by-process claims, according to MPEP 2113, that while the structure implied by the process steps should be considered when assessing the patentability of product-by-process claims over the prior art, especially where the product can only be defined by the process steps by which the product is made, or where the manufacturing process steps would be expected to impart distinctive structural characteristics to the final product. See, e.g., In re Garnero, 412 F.2d 276, 279, 162 USPQ 221, 223 (CCPA 1979), and that the claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process." In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985).
It is further noted that the only process steps are storing, leukoreducing, and oxygen and carbon dioxide reducing whole blood.
As defined above, the process step of storing only refers to keeping or accumulating the blood for future use. It is not limited to any particular amount of time nor storage methods. Thus, whole blood in a collection bag after leukapheresis would still reads on this limitation. Additionally, the claim could read on simply collecting blood in vials directly from a patient (donor) because the timing in which the storing occurs is not defined the claims and therefore, blood drawn from a patient in vials (stored) and subsequently leukoreduced is still stored leukoreduced whole blood. Additionally, the level of leukoreduction is not defined, and therefore, the whole may still have some level of white blood cells.
Therefore, the claim does not include process steps where the product can only be defined by the process steps by which the product is made, or where the manufacturing process steps would be expected to impart distinctive structural characteristics to the final product.
The claim additionally states that the stored leukoreduced whole blood composition, which is specifically stored oxygen and carbon dioxide reduced leukoreduced whole blood with platelets (OCR-LRWB+PLT), has the property of having greater 2,3-DAG level after 15 days of storage than before (prior) to storage. However, the claim is only drawn to a “stored” leukoreduced whole blood composition. As above, this implies storage for any amount of time. Thus, this step and corresponding property have been interpreted as being optional and not necessarily limiting the stored leukoreduced whole blood composition.
Furthermore, the claim describes “pre-storage” properties of the leukoreduced whole blood. However, the claim is drawn to a “stored” leukoreduced whole blood composition, not a “pre-stored” composition. Therefore, this property has been interpreted not necessarily limiting the stored leukoreduced whole blood composition.
As a result, the only properties that have been interpreted as limiting to the stored leukoreduced whole blood composition are a) that it has an SO2 level of 30% or less and b) a partial pressure of carbon dioxide of less than 60 mmHg.
Turning to the prior art, Yoshida 2012 discloses a stored “red blood cell sample” (paragraph [0005]; claim 1). Yoshida discloses that this sample can be whole blood specifically (paragraph [0006]; claim 14). Yoshida 2012 discloses that the sample can be treated to remove leukocytes (leukoreduced) (paragraph [0011]).
Yoshida 2012 discloses that the sample can be depleted of both oxygen and carbon dioxide and stored in an oxygen and carbon dioxide impermeable environment for storage (claim 1; paragraph [0006]) (thus, the blood composition is both oxygen and carbon dioxide reduced (OCR), and stored under OCR conditions).
In regards to platelets, while Yoshida 2012 is silent on whether the blood comprises platelets. However, since Yoshida explicitly discloses that the sample can be “whole blood” (paragraph [0006]; claim 14), which a person of ordinary skill in the art would have recognized that the composition comprises platelets.
It is noted that although in some embodiments Yoshida 2012 discloses that a PRP fraction was discarded (paragraph 26), it is well-known that at least some platelets co-centrifuge with the RBC fraction and instant claims do not require a specific number of platelets. Moreover, again as above, Yoshida 2012 explicitly discloses that the sample can be “whole blood” which comprises platelets.
Again, Yoshida 2012 discloses that both O2 and CO2 are reduced from the blood (paragraph [0006]). Yoshida discloses that the partial pressure of O2 and CO2 can be reduced to about 10 mmHg and 5 mmHg, respectively (paragraph [0015]).
A partial pressure of 5 mmHg CO2 overlaps with the range of less than 60 mmHg as in claim 1 (or between 1 and 60 mmHg as in claim 39; or between 1 and 20 mmHg as in claim 90).
In regards to oxygen, as evidenced by Severinghaus, oxygen at a partial pressure of 10 mmHg (mmHg = 1 Torr) is percent saturation of about 9.58%, which is less than 30% as in claim 1 (or 20% as in claim 38; or 10% as in claim 90). Note that in regard to claims 89-90, as stated above, the “pre-storage” conditions are optional and have not been considered to limit the structure of the “stored” composition.
Finally, in regards to 2,3-DPG levels over time, as above, this has been interpreted as optional step, and the process steps do not require storing the whole blood for more than 15 days. Additionally, this appears to be a natural consequence property of storing the composition for at least 15 days in the conditions as in claim 1.
Moreover, as disclosed by Yoshida 2012, removal of carbon dioxide provides for improved maintenance of 2,3-DPG (paragraph [0007]), and removal of oxygen and carbon dioxide results in higher levels of 2,3-DPG following three weeks of storage compared to samples in which either oxygen nor carbon dioxide were depleted (paragraphs [0021, 0033]).
Therefore, the carbon dioxide and oxygen reduced blood compositions as disclosed by Yoshida 2012 would result in a greater 2,3-DPG levels after 15 days of storage.
In regards to the effect of the preamble, that the composition is “for” transfusion to a trauma patient in need of multiple transfusions, Applicant should note that this is an intended use of the composition (see MPEP 2111.02). Since the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention and does not result in a structural difference between the claimed invention and the prior art, it is not considered limiting. Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020); Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020); In re Otto, 312 F.2d 937, 938, 136 USPQ 458, 459 (CCPA 1963).
However, even if it were, Yoshida 2012 discloses that the composition can be transfused to patients (paragraph [0022]), the blood composition of Yoshida 2012, is at least capable of performing this intended use.
In regards to claim 40, Yoshida discloses embodiments wherein AS-3 (which comprises citrate-phosphate-dextrose and adenine) is added to is added to blood (paragraph [0031]).
In regards to claim 41, whether the OCR-LRWB has reduced levels of a biologic modifier (BRM) selected from the group consisting of a cytokine, a chemokine, an ispropstane, and an oxidized lipid product relative to non-OCR-LRWB, this appears to be a property of OCR-LRWB not a limitation per se.
This is supported by the specification which states “oxygen reduced leukoreduced whole blood (OR-LRWB) . . . has reduced levels of biological response modifiers (BRMs) relative to conventionally stored whole blood (paragraph [0074]).
Additionally, as evidenced by Sharma, it is known in the art that the process of leukoreduction itself is sufficient reduce inflammatory cytokines (BRMs) accumulation during storage which reduces immune responses in patients (with a variety of conditions) following transfusion (Timing of Leukofiltration, p4).
Therefore, since Yoshida 2012 discloses the stored leukoreduced whole blood product of claim 35, the product as disclosed by Yoshida 2012, would appear to have the same properties as in claims 41 absent evidence to the contrary.
In regards to claims 42-46 and 48, whether the leukoreduced whole blood product has reduced inflammatory response relative to a patient in need with a different blood product (as are any of the other conditions in claims 43-48, such as “reduced immune modulation”, as in claim 43), these are also properties of the if transfused in the patient and are intended uses.
In the instant case, as above, as evidenced by Sharma, it is known in the art that the process of leukoreduction itself is sufficient reduce inflammatory cytokines (BRMs) accumulation during storage which reduces immune responses in patients (with a variety of conditions) following transfusion (Timing of Leukofiltration, p4).
Therefore, since Yoshida 2012 discloses the stored leukoreduced whole blood product of claim 35, the product as disclosed by Yoshida 2012, would appear to have the same properties as in claims 42-46 and 48 or would be expected to be suitable for these intended uses absent evidence to the contrary.
In regards to claims 49-52, regards to whether the leukoreduced whole blood has equivalent or better coagulation parameters as measured by thromboelastography (or equivalent or better parameters or levels of conditions in claims 50-52), these are properties of stored leukoreduced whole blood, if measured, and do not require additional process steps. Thus, they have been interpreted as optional. Furthermore, since Yoshida 2012 discloses the stored leukoreduced whole blood product of claim 35, the product as disclosed by Yoshida 2012, would appear to have the same properties as in claims 449-52 is further process steps were performed, absent evidence to the contrary.
In the instant case, as above, as evidenced by Sharma, it is known in the art that the process of leukoreduction itself is sufficient reduce platelet-refractoriness (p.5, col2, see Table 3), thereby allowed stored leukoreduced blood to exhibit equivalent or greater TEG coagulation parameters than stored non-leukoreduced blood.
In regards to claim 53, Yoshida discloses that the blood can be stored for at least three weeks (paragraph [0006]).
In regards to claim 91, these are intended uses of the preamble (see MPEP 2111.02). As discussed above, Yoshida 2012 discloses that the composition can be transfused to patients broadly (paragraph [0022]). Therefore, Yoshida 2012 appears suitable for these intended uses absent evidence to the contrary.
Therefore, Yoshida discloses the invention as claimed.
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.
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.
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 92 is rejected under 35 U.S.C. 103 as being unpatentable over Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited) in view of view of Masse (Transfus Clin Biol, 2001, previously cited), as evidenced Severinghaus (Journal of Applied Physiology, 46(3): 599-602, 1979, previously cited).
Yoshida discloses claim 35 as discussed above.
In regards to claim 92, as above, Yoshida 2012 teaches that the whole blood can be depleted, but is silent as to the level of reduction. However, a person ordinary skill in the art would have been motivated to reduce white blood cells by at least 5 logs in order to reduce the chances of triggering an immune response in recipients, and because as taught by Masse, this reduces more than 99.90% of leukocytes (Leukocyte technology, p298). Furthermore, because as taught by Masse, methods for reducing leukocytes by 5 logs is known in the art (Leukocyte technology, p298), it could have been done with predictable results and a reasonable expectation of success.
Therefore, the combined teachings of Yoshida 2012 and Masse renders the invention unpatentable as claimed.
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. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); 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); 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) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used.

Claims 35-46, 48-53, and 89-92 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of copending Application No. 17/772,947 as evidenced by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited).
Although the conflicting claims of copending Application No. 17/772,947 are not identical to the currently prosecuted claims 35-46, 48-53, and 89-92, they are not patently distinct from each other because said claims of both inventions are drawn to stored oxygen-reduced blood that can be whole blood (which comprises platelets) and leukoreduced, wherein the blood is oxygen and carbon dioxide-reduced, at levels of less than 30% and 60 mm Hg, respectively.
While the co-pending Application is silent as to levels of 2,3-DPG after 15 days of storage, this has been interpreted as optional step, and the process steps do not require storing the whole blood for more than 15 days. Additionally, this appears to be a natural consequence property of storing the composition for at least 15 days in the conditions as in claim 1.
Moreover, as evidenced by Yoshida 2012, removal of carbon dioxide provides for improved maintenance of 2,3-DPG (paragraph [0007]), and removal of oxygen and carbon dioxide results in higher levels of 2,3-DPG following three weeks of storage compared to samples in which either oxygen nor carbon dioxide were depleted (paragraphs [0021, 0033]).
Therefore, a carbon dioxide and oxygen reduced blood would result in a greater 2,3-DPG levels after 15 days of storage.
In regards to whether the stored blood can be administered to a trauma patient, in regards to the effect of the preamble, that the composition is “for” transfusion to a trauma patient in need of multiple transfusions, Applicant should note that this is an intended use of the composition (see MPEP 2111.02). Since the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention and does not result in a structural difference between the claimed invention and the prior art, it is not considered limiting. Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020); Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020); In re Otto, 312 F.2d 937, 938, 136 USPQ 458, 459 (CCPA 1963).
However, even if it were, the co-pending Application is still drawn to a stored oxygen-reduced blood that can be whole blood (which comprises platelets) and leukoreduced, wherein the blood is oxygen and carbon dioxide-reduced, at levels of less than 30% and 60 mm Hg, respectively, and therefore, is suitable for this intended use.
This is a provisional nonstatutory double patenting rejection.
Claims 35-46, 48-53, and 89-92 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of copending Application No. 18/152,140 as evidenced by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited).
Although the conflicting claims of copending Application No. 18/152,140 are not identical to the currently prosecuted claims 35-46, 48-53, and 89-92, they are not patently distinct from each other because said claims of both inventions are drawn to stored oxygen-reduced blood that can be whole blood (which comprises platelets) and leukoreduced, wherein the blood is oxygen and carbon dioxide-reduced, at levels of less than 30% and 60 mm Hg, respectively.
While the co-pending Application is silent as to levels of 2,3-DPG after 15 days of storage, this has been interpreted as optional step, and the process steps do not require storing the whole blood for more than 15 days. Additionally, this appears to be a natural consequence property of storing the composition for at least 15 days in the conditions as in claim 1.
Moreover, as evidenced by Yoshida 2012, removal of carbon dioxide provides for improved maintenance of 2,3-DPG (paragraph [0007]), and removal of oxygen and carbon dioxide results in higher levels of 2,3-DPG following three weeks of storage compared to samples in which either oxygen nor carbon dioxide were depleted (paragraphs [0021, 0033]).
Therefore, a carbon dioxide and oxygen reduced blood would result in a greater 2,3-DPG levels after 15 days of storage.
This is a provisional nonstatutory double patenting rejection.
Claims 35-46, 48-53, and 89-92 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 35, 49, 89-105 of copending Application No. 17/954,138 in view of Yoshida et al. (US2013/0004937A1, 2013, on IDS 04/27/2021, previously cited) as evidenced by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited).
Although the conflicting claims of copending Application No. 17/954,138 are not identical to the currently prosecuted claims 35-46, 48-53, and 89-92, they are not patently distinct from each other because said claims of both inventions are drawn to stored oxygen-reduced blood that can be whole blood (which comprises platelets) , wherein the blood is oxygen and carbon dioxide-reduced, at levels of less than 30% and 60 mm Hg, respectively.
While the copending Application does not explicitly require that the blood composition be leukoreduced, a person of ordinary skill in the art would have been motivated to leukoreduce the blood because Yoshida teaches that leukoreduction may include removing white blood cells that can carry viruses and cause fevers (paragraph [0026]). Furthermore, because Yoshida teaches a system leukoreducing whole blood (paragraphs [0026, 0035, etc.; Fig. 2), it could have been done with predictable results and a reasonable expectation of success.
While the co-pending Application is silent as to levels of 2,3-DPG after 15 days of storage, this has been interpreted as optional step, and the process steps do not require storing the whole blood for more than 15 days. Additionally, this appears to be a natural consequence property of storing the composition for at least 15 days in the conditions as in claim 1.
Moreover, as evidenced by Yoshida 2012, removal of carbon dioxide provides for improved maintenance of 2,3-DPG (paragraph [0007]), and removal of oxygen and carbon dioxide results in higher levels of 2,3-DPG following three weeks of storage compared to samples in which either oxygen nor carbon dioxide were depleted (paragraphs [0021, 0033]).
Therefore, a carbon dioxide and oxygen reduced blood would result in a greater 2,3-DPG levels after 15 days of storage.
This is a provisional nonstatutory double patenting rejection.
Claims 35-46, 48-53, and 89-92 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 19, 22-23, 28, 30, 33-36, 38, 41, 43-47 of copending Application No. 16/289,118 in view of Yoshida et al. (US2013/0004937A1, 2013, on IDS 04/27/2021, previously cited) as evidenced by Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited).
Although the conflicting claims of copending Application No. 16/289,118 are not identical to the currently prosecuted claims 35-46, 48-53, and 89-92, they are not patently distinct from each other because said claims of both inventions are drawn to stored oxygen-reduced blood that can be whole blood (which comprises platelets) , wherein the blood is oxygen and carbon dioxide-reduced, at levels of less than 30% and 60 mm Hg, respectively, and with 2,3-DPG levels that are higher after storage.
While the copending Application does not explicitly require that the blood composition be leukoreduced, a person of ordinary skill in the art would have been motivated to leukoreduce the blood because Yoshida teaches that leukoreduction may include removing white blood cells that can carry viruses and cause fevers (paragraph [0026]).

Claims 35-46, 48-53, and 89-92 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 109-116 and 121-128 of copending Application No. 18/297,193 in view of Yoshida et al. (US20120225416A1, on IDS 04/27/2021, hereafter “Yoshida 2012”, previously cited).
Although the conflicting claims of copending Application No. 18/297,193 are not identical to the currently prosecuted claims 35-46, 48-53, and 89-92, they are not patently distinct from each other because said claims of both inventions are drawn to stored oxygen-reduced blood that can be whole blood (which comprises platelets) , wherein the blood is oxygen-reduced, at levels of less than 30%.
While the co-pending Application does not explicitly requiring reducing carbon dioxide to a level of 69 mmHg or less, a person of ordinary skill in the art would have been motivated to do so because Yoshida 2012 teaches that depleting red blood cells samples (including whole blood) enhances red blood cell quality and survival during storage (paragraph [0011]; claim 14). Furthermore, because Yoshida 2012 teaches methods for depleting whole blood samples of carbon dioxide below 60 mmHg (claims 1, 10, and 14), it could have been done with predictable results and a reasonable expectation of success.
In regards to an increased 2,3-DAG level after 15 days of storage, as discussed above, this has been interpreted as optional step, and the process steps do not require storing the whole blood for more than 15 days. Additionally, this appears to be a natural consequence property of storing the composition for at least 15 days in the conditions as in claim 1.
However, as taught by Yoshida 2012, removal of carbon dioxide provides for improved maintenance of 2,3-DPG (paragraph [0007]), and removal of oxygen and carbon dioxide results in higher levels of 2,3-DPG following three weeks of storage compared to samples in which either oxygen nor carbon dioxide were depleted (paragraphs [0021, 0033]).
Therefore, a carbon dioxide and oxygen reduced blood would result in a greater 2,3-DPG levels after 15 days of storage.
In regards to whether the stored blood can be administered to a trauma patient, in regards to the effect of the preamble, that the composition is “for” transfusion to a trauma patient in need of multiple transfusions, Applicant should note that this is an intended use of the composition (see MPEP 2111.02). Since the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention and does not result in a structural difference between the claimed invention and the prior art, it is not considered limiting.

However, even if it were, the co-pending Application is still drawn to a stored oxygen-reduced blood that can be whole blood (which comprises platelets) and leukoreduced, wherein the blood is oxygen-reduced, at levels of less than 30%, and is therefore, is suitable for this intended use.
