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 . Status of claims: 100-119 are pending below. Response to Arguments Applicant’s arguments with respect to claims 100-119 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant’s remarks – (page 4-5) Applicant argued Statement of Common Ownership, establishing that the present application and Staker were commonly owned or subject to an obligation of assignment to Apton Biosystems, Inc. not later than the effective filing date of the present application. Applicant notes that while the present application and Staker have since been assigned to a different entity - Illumina Cambridge Limited - these patent properties remain commonly owned and were commonly owned or subject to assignment to the same entity (i.e., Apton Biosystem, Inc.) not later than the September 19, 2018 effective date of the present application. Accordingly, Staker is disqualified as prior art under 35 U.S.C. 102(b)(2)(C). See MPEP 717.02(a). As Staker is not prior art under 35 USC 102(a)(1) and is disqualified as 35 USC 102(a)(2) prior art under 35 USC 102(b)(2)(C). Please see Remarks for further detail. Examiner’s response – Examiner respectfully agree. And updated search has provided a new combination of prior arts that teaches the instant invention. Please see the Office Action below for further details. 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. Claims 100-118 are rejected under 35 U.S.C. 103 as being unpatentable over Quake (2006/0019267) in view of KLEIN et al (US 2017/0128365) and Hesselberth (US 2015/0087526).

Quake et al teaches all the subject matter above, but not the following: (a) treating the two molecules with an attractant or a repellant. KLEIN et al (US 2017/0128365) teaches the following subject matter: (a) treating the two molecules with an attractant or a repellant (0315 detail use of zwitterion as an electrostatic attraction). Quake et al and KLEIN et al are both in the field of image analysis, especially analysis of molecules on a substrate regarding measurement of centers (KLEIN et al detail in 0311) such that the combine outcome is predictable. Therefore it would have been obvious to one having ordinary skill before the effective filing date to modify Quake et al by KLEIN et al regarding attractant or repellant prove an effect highly effective lubrication hydrated charged groups as disclosed by KLEIN et al in 0312. Quake et al and KLEIN et al both teach all the subject matter above, but not the following: Separate from each other.

Claim 103: KLEIN et al teach: The method of claim 100, wherein the treating the two molecules with the attractant or the repellant comprises encasing the two molecules in a shell of the attractant or the repellant (0499 detail coverage/encasing). Claim 104: KLEIN et al teach: The method of claim 103, further comprising removing the shell of the two molecules prior to imaging the substrate (0458 detail rinsed in de-ionized water to remove; 0551 detail attributed to removal of residual intact). Claim 105: KLEIN et al teach: The method of claim 100, wherein the placing of the two molecules onto the substrate comprises dragging or pulling the two molecules (0315 detail use of zwitterion as an electrostatic attraction). Claim 106: Quake teach: The method of claim 100, further comprising exposing the two molecules placed onto the substrate to a gas-liquid interface such that the two molecules form a monolayer across the substrate (0131 detail tachment can be achieved by anchoring a hydrophobic chain into a lipidic monolayer or bilayer.). Claim 107: Quake teach: The method of claim 106, wherein the gas-liquid interface is an air-water-interface (figure 6 and interface of glass (expose to air) and water, where refracted light was reflected back and not continued in the liquid phase as the critical angel for total internal reflection). Claim 108: Quake teach: The method of claim 100, wherein the two molecules comprise concatemers (0333 comparing of sequence with one or more nucleotides downstream of the region of interest,). Claim 109: Quake teach: The method of claim 108, wherein the concatemers are hybridized to ssDNA hairs (0102-0103; 0105-0106; 0117; 0130).
