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 . Claims 1 – 15 are canceled. 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. Claims 1 & 45 & 47 are 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 claims 1 & 45 The phrase “electromagnetic sample spinning field” is ambiguous. Does this mean the sample itself contains a “spinning field”? Or does it mean that the spinning sample itself is subject to an electromagnetic field that produces the torque? For purposes of examination the Examiner will assume “broadest possible interpretation”—i.e., the sample is subjected to a magnetic field. Regarding claim 47 The claim uses the phrase “particles not packed in a rotor”. Does this mean these particles of the sample are not rotating? It would be helpful to clarify this language. 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. Claim(s) 16, 25, 30, 31, 32, 35 – 38, 45, 46 is/are rejected under 35 U.S.C. 103 as being unpatentable over Schoeter (CN-104793157-A) in view of Song et al. (US-20160033599-A1). Regarding claim 16 Schoeter discloses A magnetic resonance device (¶ 2 under Background Technology) comprising: a sample spinning apparatus (¶ 2 under Invention Contents) configured to spin a sample about a sample spinning axis (¶ 8 under Background Technology); and a resonance structure for exposing the spinning sample to an electromagnetic excitation field to manipulate a nuclear or electronic spin state of the sample (¶ 2 under Background Technology), Although strongly implied, Schroeter does not explicitly teach “wherein the sample spinning apparatus is configured to exert a torque on the sample by interaction of the sample with an electromagnetic sample spinning field”. Song, however, discloses wherein the sample spinning apparatus is configured to exert a torque on the sample by interaction of the sample with an electromagnetic sample spinning field ([0035]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the facility of the “torque exerted on sample by electromagnetic field” as taught by Song in the device of Schoeter. The justification for this modification would be to generate an NMR spectrum ([0035]). Regarding claim 25 Schoeter in view of Song teach the magnetic resonance device of claim 16, Song, applied to claim 25, further teaches comprising a sample support structure configured to support the sample ([0017], the flat-bottomed container is the “sample support structure”).

Regarding claim 36 Schoeter in view of Song teach the magnetic resonance device of claim 16, Song, applied to claim 36, further teaches wherein the magnetic resonance device comprises a cylindrical probe body defining a cylinder axis ([0037]), and wherein the sample spinning axis has an orientation at the magic angle Θₘ⁻ = arctan √2 relative to the cylinder axis of the cylindrical probe body ([0005]). Regarding claim 37 Schoeter discloses A magnetic resonance system (¶ 2 under Background Technology), comprising a magnet device for generating a static magnetic field along a static field direction (¶ 2 under Background Technology) and a magnetic resonance device comprising: a sample spinning apparatus (¶ 2 under Invention Contents) configured to spin a sample about a sample spinning axis (¶ 8 under Background Technology); and a resonance structure for exposing the spinning sample to an electromagnetic excitation field to manipulate a nuclear or electronic spin state of the sample (¶ 2 under Background Technology), Schoeter does not disclose “wherein the sample spinning apparatus is configured to exert a torque on the sample by interaction of the sample with an electromagnetic sample spinning field”. Song, however, teaches wherein the sample spinning apparatus is configured to exert a torque on the sample by interaction of the sample with an electromagnetic sample spinning field ([0035]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the facility of the “torque exerted on sample by electromagnetic field” as taught by Song in the device of Schoeter. The justification for this modification would be to generate an NMR spectrum ([0035]).

Regarding claim 45 Schoeter discloses A magnetic resonance method (¶ 2 under Background Technology), comprising: exposing a sample to a static magnetic field along a static field direction (¶ 2 under Background Technology); spinning the sample about a sample spinning axis (¶ 8 under Background Technology); creating an excitation field to manipulate a spin state of the spinning sample; and measuring a response of the sample to the manipulation of the spin state, wherein torque is exerted on the sample by interaction of the sample with an electromagnetic sample spinning field. Regarding claim 46 Schoeter in view of Song teach the magnetic resonance method of claim 45, Song, applied to claim 46, further teaches wherein the sample spinning axis has an orientation at the magic angle Θₘ= = arctan √2 relative to the static field direction ([0005]).
