Office Action

§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 . Election/Restrictions Applicant's election with traverse of Group I, and the species “quality” from the cell-relevant data in the reply filed on 06/16/2025 is acknowledged. Regarding Group I, the traversal is on the ground(s) that the method cannot be performed independently of the claimed system and merely recites a use of it. This is not found persuasive because the restriction is on the grounds that the common technical feature, the cell quantifying component, does not define a contribution over the prior art of reference. The requirement is still deemed proper and is therefore made FINAL. Claims 42-45 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 06/16/2025. It is noted that Claim 44 has further been cancelled. Regarding the species election, the traversal is on the ground(s) that the various types of cell relevant data recited in Claim 34 are no patentably distinct, nor are they mutually exclusive. Examiner withdraws the species restriction and further notes the applicant has now submitted on record the different types of cell relevant data in Claim 34 are not patentably distinct and therefore, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention 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 39 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. Regarding Claim 39, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). 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 31-34 and 36-41 are rejected under 35 U.S.C. 103 as unpatentable over Fraser et al. (US20040106196A1). Regarding Claim 31, Fraser teaches the following: Systems for using cells derived from adipose tissue that are placed directly into a recipient (para 15)(a system for cell processing) A processing device which measures the amount of tissue/fluid to be moved along a particular pathway using volumetric mechanisms (para 95)(a cell quantifying component configured for quantifying a volume flow in the system) Alternatively, the volume may be determined by measurement of the weight of material (para 97)(quantifying the weight of the tissue) An agitation/incubation chamber 102 where mixing is done by agitation rocking (para 99) which creates the micro fragmented tissue, the tissue being adipose tissue (Abstract), and placed back into the recipient (para 68)(autologous)(an Autologous Micro-Fragmented Adipose Tissue component (AMFAT)) A cell collection container 26 which includes a cell concentrator like a centrifuge device (para 77)(a centrifuge component) The software component includes automated collection of “run data” including … temperature and volume measurements, tissue volume and cell number parameters (para 100)(system configured for generating cell-relevant data) Fraser further teaches the device could be incorporated into the controller system (para 100) and the steps such as the mixing mechanisms may be automated (para 95). Fraser does not explicitly teach at least one operational parameter of the AMFAT component or the centrifuge component is generated base on cell-relevant data. However it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to automate a parameter of the mixing mechanism (part of the AMFAT component) based on the cell-relevant data that is being collected by the software component and incorporated into the controller system. One would have been motivated to make this modification as it would allow further automation of operational parameter adjustment which would result in improved performance of the procedures (para 95). Regarding Claim 32, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches the tissue collection container 12 include a tissue collecting inlet port 14 (para 75) and the tissue collection container is placed into the agitation chamber 102 where the tissue is collected prior to placement or while it is positioned within the device (para 96-97)(the AMFAT component comprises an inlet for feeding tissues into the AMFAT component). Regarding Claim 33, Fraser teaches all of the limitations of Claim 32 (see above). Fraser further teaches the agitation chamber is agitated by rocking (para 99) requiring there to be a component which rocks or swivels the agitation chamber. As above, Fraser further teaches the steps such as the mixing mechanisms may be automated (para 95). Fraser does not explicitly teach at least one operational parameter of the swivel component is generated base on cell-relevant data. However it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to automate a parameter of the mixing mechanism (swivel component) based on the cell-relevant data that is being collected by the software component and incorporated into the controller system. One would have been motivated to make this modification as it would allow further automation of operational parameter adjustment which would result in improved performance of the procedures (para 95). Regarding Claim 34, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches The software component includes automated collection of “run data” including … temperature and volume measurements, tissue volume and cell number (quality) parameters (para 100)(a portion of the cell relevant data is generated by the cell quantifying component and the cell relevant data comprises at least one of… temperature or quality). Regarding Claim 36, Fraser teaches all of the limitations of Claim 33 (see above). Fraser further teaches additive line 42 is provided to deliver one or more enzymes to the tissue collection chamber (para 83)(an enzyme component, configured to add at least one enzyme in the volume flow). Regarding Claim 37, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches a temperature control device to change the temperature of the fluid being deliver to tissue collecting container (para 81)(a temperature controller, configured to maintain an optimized predetermined temperature of the volume flow) Regarding Claim 38, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches one or more additives may be added to the various containers as needed to enhance the results (para 93)(an additive component , configured to add at least one predetermined additive to an end product of the system). Regarding Claim 39, Fraser teaches all of the limitations of Claim 36 (see above). Fraser further teaches additive line 42 is provided to deliver one or more enzymes to the tissue collection chamber (which is part of the agitation chamber)(para 83)(configured to feed at least one enzyme from the enzyme component to the swivel component). Regarding Claim 40, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches the tissue collection chamber includes an aspiration port 18 which is coupled to a suction device 20 which may be a syringe, which should be capable of aspirating tissue from a patient (para 76)(one syringe driver, configured to transfer the volume flow in the system). Regarding Claim 41, Fraser teaches all of the limitations of Claim 31 (see above). Fraser further teaches a user interface screen 106 (implying user data) and the volume which may be determined by measurement of the weight (cell-relevant data) may displayed on the user interface screen (configured to extract user data and further associate the user data with the cell-relevant data). Alternatively, the user interface configured to extract user data and further associate the user data with the cell-relevant data is an intended use of the device. A recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim (see MPEP 2114). The user interface of Fraser would be capable of associating the cell-relevant data with the user data and therefore meets the claim.
