`
`Introduction
`Momentum Dynamics Corporation (“Petitioner”) requests inter partes review
`
`of claims 1-8 (“Challenged Claims”) of U.S. Patent No. 9,306,635 (Ex. 1001,
`
`“’635 patent”), A. Kurs, et al, titled “Wireless Energy Transfer with Reduced
`
`Fields.” WiTricity Corp. (“Patent Owner”) is the Patent Owner of record.
`
`The ’635 patent relates to the use of magnetic resonators to wirelessly transfer
`
`energy. ’635 patent Abstract, 5:18-65. This technology, however, dates back to
`
`Nikola Tesla and his work in the late 1800s on the “Tesla coil.” In these systems,
`
`a source magnetic resonator produces an oscillating magnetic field that induces
`
`current in a magnetic resonator connected to a load device. But as a byproduct, such
`
`systems emit electromagnetic radiation into the surrounding area. To reduce this
`
`radiation, a second source resonator can be driven out of phase from the first source
`
`resonator such that their magnetic fields at least partially cancel—a solution that was
`
`also well-known in the art.
`
`Yet the ’635 patent is directed to this very solution—cancelling the magnetic
`
`field of a magnetic resonator using another magnetic resonator with an opposing
`
`magnetic field. Thus, as discussed below, U.S. Patent No. 8,698,350 (Ex. 1005,
`
`“Kanno”), which was not considered during prosecution of the ’635 patent,
`
`anticipates and renders obvious the Challenged Claims. Kanno discloses a wireless
`
`energy transmission system that uses magnetic resonators to transfer power from an
`
`1
`
`
`
`
`energy source to a load device in the same way as the ’635 patent. Kanno, Abstract,
`
`Petition for Inter Partes Review of USP 9,306,635
`
`6:50-63, Fig. 7. Specifically, Kanno describes the same technique for reducing
`
`electromagnetic radiation emitted by the system—by driving the source magnetic
`
`resonators out of phase such that their “resonant magnetic fields … will at least
`
`partially cancel each other.” Id. 20:62-21:4; Arnold Decl. ¶ 110.
`
`As shown below, Kanno, which was not considered during prosecution of the
`
`’653 patent, discloses every element of the Challenged Claims. Petitioner therefore
`
`requests that the Challenged Claims be found unpatentable.
`
`II.
`
`Identification of Challenges (37 C.F.R. § 42.104(b))
`• Ground 1: Claims 1-8 are unpatentable under §102 over Kanno.
`
`• Ground 2: Claims 1-8 are unpatentable under §103 over Kanno.
`
`III. Background
`A. The ’635 Patent
`The ’635 patent “relates to wireless energy transfer using coupled
`
`electromagnetic resonators.” ’635 patent 4:16-17. As the ’635 patent acknowledges,
`
`“wireless energy
`
`transfer using coupled electromagnetic resonators” was
`
`well-known. Id. 4:16-35. Indeed, the ’635 patent states that “wireless energy transfer
`
`resonators” and “important considerations for resonator-based power transfer
`
`includ[ing] resonator efficiency and resonator coupling” had been discussed
`
`extensively in admitted prior art U.S. Pat. Pub. Nos. 2010/0237709 (Ex. 1006,
`
`2
`
`
`
`
`“Hall”) and 2010/0181843 (Ex. 1007, “Schatz”). Schatz 4:22-35; see also ’635
`
`Petition for Inter Partes Review of USP 9,306,635
`
`patent at 1:23-35 (“The wireless energy transfer resonators and components that may
`
`be used have been described in [Hall and Schatz] … which are incorporated in their
`
`entirety as if fully set forth herein.”); Arnold Decl. (Ex. 1003) ¶ 14.
`
`1. Magnetic Resonators
`A resonator “store[s] energy in at least two different forms[] where the stored
`
`energy is oscillating between the two forms.” Hall [0135]. 1 For example,
`
`a pendulum is a mechanical resonator that oscillates between potential and kinetic
`
`energy. Electromagnetic resonators oscillate between magnetic and electrical
`
`energy. Id. [0012]. The frequency of this oscillation is called the “resonant
`
`frequency.” Id. [0135], [0194]; Arnold Decl. ¶¶ 15-16.
`
`Electromagnetic resonators oscillate between magnetic energy stored in an
`
`inductor and electrical energy stored in a capacitor. Arnold Decl. ¶¶ 15-21. Figure
`
`6a of Hall below is a circuit model of an electromagnetic resonator. Hall [0185]. The
`
`capacitor (C) stores electrical energy in the electric field between its metal plates.
`
`Id. [0187]. The inductor (L) is a conductive coil that stores magnetic energy in its
`
`magnetic field. Id. [0187]-[0188]; Arnold Decl. ¶¶ 19-21.
`
`
`1 Although the remainder of this Petition cites Hall, similar disclosures can be
`
`found in Schatz. Arnold Decl. 8 n.1.

`
`
`
`
`
`Hall Fig. 6a.
`
`Petition for Inter Partes Review of USP 9,306,635
`
`
`
`A capacitor has an original polarity (e.g. one plate is positive and one plate is
`
`negative). Arnold Decl. ¶ 20. When the capacitor discharges, current flows through
`
`the inductor (e.g., clockwise) and generates magnetic energy stored in the inductor’s
`
`magnetic field. Hall [0185]. When the capacitor is fully discharged, the stored
`
`magnetic energy causes current to continue to flow in the same direction (e.g.,
`
`clockwise). Id. This continued current charges the capacitor on the opposite side of
`
`its original polarity. See id. (“[T]he inductor 108 … transfers energy back into
`
`electric field energy stored in the capacitor 104.”); Arnold Decl. ¶ 20. The capacitor
`
`now has an opposite polarity, and the charged capacitor discharges in the opposite
`
`direction such that current flows through the inductor in the opposite direction (e.g.,
`
`counterclockwise). Arnold Decl. ¶ 20. The inductor’s magnetic field stores and
`
`releases this energy to charge the capacitor to have its original polarity. As this
`
`process repeats, the oscillating current (e.g., current switching directions) in the
`
`inductor generates an oscillating magnetic field around the inductor. Id. ¶¶ 20-21.
`
`Hall describes “magnetic resonators” as electromagnetic resonators that are
`
`“designed such that the energy stored by the electric field is primarily confined
`
`4
`
`
`
`
`within the structure and … the energy stored by the magnetic field is primarily in
`
`Petition for Inter Partes Review of USP 9,306,635
`
`the region surrounding the resonator.” Hall [0012]. In other words, energy is
`
`transferred between magnetic resonators primarily through their magnetic fields. Id.
`
`[0182]; Arnold Decl. ¶¶ 22-23.
`
`Magnetic resonators have been known for over 100 years. This technology
`
`dates back to Nikola Tesla’s work in the late 1800s and his development of the Tesla
`
`coil. See Stark 16 (Ex. 1008); see also U.S. Pat. 454,622 (Ex. 1009 “Tesla”). A Tesla
`
`coil is a coupled magnetic resonance system in which two circuits, each having a
`
`capacitance and an inductance, share a resonant frequency. Stark 12 (“[T]he
`
`traditional Tesla coil is comprised of two coupled second order systems sharing a
`
`resonant frequency”), 21 (“In the case of an electrical circuit, a second order system
`
`implies that there is both a capacitance and an inductance.”). In operation, “resonant
`
`circuits couple[] in such a way as to take energy stored in the primary side of the
`
`circuit and transfer it onto the secondary coil.” Id. 41; Arnold Decl. ¶ 24
`
`Hall shows magnetic resonators transferring energy using the same principles
`
`as the Tesla coil. Figure 1b shows a source magnetic resonator 102S (left) that
`
`transfers energy over a distance D to a device magnetic resonator 102D (right).
`
`5
`
`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`
`Hall Fig. 1b, [0029], [0156]. Each resonator has an inductor “loop” or “coil” with
`
`capacitor plates at its ends. Id. [0187], [0188] (“[W]e may use the terms “loop” or
`
`“coil” to indicate generally a conducting structure (wire, tube, strip, etc.), enclosing
`
`a surface of any shape and dimension, with any number of turns.”), Fig. 6d.
`
`The source resonator is driven by a power supply and produces an oscillating
`
`magnetic field. Id. [0156], [0185]. This induces an oscillating current in the inductor
`
`loop of the device magnetic resonator. See id. [0185]. The induced current can be
`
`supplied to a load device such as a battery. Id. [0156]; Arnold Decl. ¶ 25.
`
`2.
`Dipole Moment
`The magnetic dipole moment of a current loop is a vector that is perpendicular
`
`to the plane of the current loop. Ex. 1010 (Physics of Life Sciences) at 437
`
`(“The magnetic dipole moment is a vector quantity … perpendicular to the plane of
`
`the current loop.”); see Hall [0239] (dipole moment is perpendicular to the plane of
`
`“capacitively-loaded inductor loop resonators”); Arnold Decl. ¶ 26. It represents the
`
`strength and direction of the magnetic field generated by the current loop. Arnold
`
`Decl. ¶ 26. The direction of the dipole moment can be determined by the right-hand
`
`6
`
`
`
`
`rule where the fingers curl in the same direction as current flow and the thumb points
`
`Petition for Inter Partes Review of USP 9,306,635
`
`in the direction of the dipole moment. Id.; Ex. 1011 (Matter & Interactions) at 725
`
`(“[C]url[] the fingers of your right hand in the direction of the conventional current,
`
`and your thumb points in the direction of the magnetic dipole moment.”)
`
`
`Because current in the inductor loop of a magnetic resonator oscillates
`
`(changes direction), the dipole moment also oscillates. This is shown, for example,
`
`in Figure 2A of the ’635 patent below. When current flows clockwise, the dipole
`
`moment (purple arrow,
`
`left) points downward, and when current flows
`
`counterclockwise, the dipole moment (purple arrow, right) points upward:
`
`
`

`
`
`
`
`
`
`’635 patent Fig. 2A (annotated, current arrows added); Arnold Decl. ¶ 27.

`
`3.
`Reduced Magnetic Fields
`The ’635 patent states that “[i]n some wireless power transfer applications,
`
`it may be beneficial to minimize or reduce the electric and magnetic fields … at
`
`distances substantially larger than the system.” ’635 patent 51:29-57. To reduce
`
`these fields, the ’635 patent drives two wireless power transfer systems out of phase
`
`such that they have opposite dipole moments. Id. 53:8-14. “[I]f the dipole moment
`
`vectors of the two systems are the same in direction and in magnitude, and one
`
`ensures to operate the systems [] out of phase, the dipole component will be canceled
`
`far from the systems.” Id. 53:11-14; Arnold Decl. ¶¶ 28-29.
`
`For example, in Figure 41 below, the first wireless power transfer system
`
`includes a first source magnetic resonator (“source 1,” blue) and a first device
`
`magnetic resonator (“device 1,” light blue). ’635 patent 53:18-20. The second
`
`wireless power transfer system includes a second source magnetic resonator (“source
`
`2,” green) and a second device magnetic resonator (“device 2,” light green). Id.
`
`’635 patent Fig. 41 (annotated).
`

`
`
`
`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`As indicated by the left/right arrows, source 1 and source 2 are out of phase
`
`(the oscillating current in source 1 flows in the opposite direction as the oscillating
`
`current in source 2) and thus have opposite dipole moments. Id. 53:8-14.
`
`Consequently, “the dipole component will be canceled far from the systems.”
`
`Id. 53:11-14; Arnold Decl. ¶¶ 30-31.
`
`B.
`Prosecution History
`The prosecution history of the ’635 patent also confirms that the concept of
`
`cancelling the magnetic field of a magnetic resonator using another magnetic
`
`resonator with an opposing dipole moment was well-known in the art.
`
`The application for the ’635 patent was filed January 28, 2013 and claims
`
`priority to a provisional filed January 26, 2012. Prior to the first office action,
`
`Patent Owner overwhelmed the Examiner by citing over 900 prior art references
`
`without explanation. Ex. 1002 (“’635 FH”) 155-211, 1699-1703, 1768-1778, 1878-
`
`1881.
`
`The Examiner rejected the pending claims as obvious over either:
`
`(1) U.S. 4,240,010 (Ex. 1012, “Buhrer”) in view of U.S. Pat. Pub. No. 2009/0051224
`
`(Ex. 1013, “Cook”); and (2) U.S. Pat. Pub. No. 2011/0125007 (Ex. 1014,
`
`“Steinberg”) in view of Cook. ’635 FH 1908. The Examiner found that each
`
`combination taught magnetic resonators comprising two inductor loops with dipole
`
`moments in opposite directions. Id. 1908-1910.
`
`9
`
`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`Figure 6 of Buhrer shows magnetic resonator coils 96 and 94 with opposite
`
`current flow (arrows along coils) and thus opposite dipole moments 98 (purple):
`
`
`Buhrer Fig. 6 (annotated); ’635 FH 1908. Because “the magnetic dipole moments
`
`are of opposite polarity,” they “offset each other in the far field.” Buhrer 7:39-42.
`
`“Thus, the level of electromagnetic radiation produced by induction coil 90 in the
`
`far field is nearly zero as discussed above.” Id. 7:42-44.
`
`Steinberg also discloses inductor coils with opposite currents (white arrows)
`
`and thus opposite magnetic dipoles (–mq and mq, purple):
`
`
`
`10
`
`
`
`
`Steinberg Fig. 2B (annotated); see also id. Fig. 1, [0072], [0075]-[0076]; ’635 FH
`
`Petition for Inter Partes Review of USP 9,306,635
`
`1909.
`
`Cook discloses the magnetic resonator components of the pending claims,
`
`including a capacitor in series with a coil having one or more loops. Cook Fig. 1,
`
`[0021]; ’635 FH 1908-1910. The Examiner thus found it was obvious to apply the
`
`known concept of using opposing dipole moments to cancel a magnetic field using
`
`magnetic resonators as described in the pending claims. ’635 FH 1908-1910.
`
`In response, Patent Owner amended the claims to require source magnetic
`
`resonators for “wireless power transfer” and argued that this arrangement
`
`distinguished over the asserted prior art. ’635 FH 2019-2022, 2023-2024 (“Buhrer
`
`does not relate to wireless power transfer” and “does not use his induction coil 90 to
`
`transfer power to resonators at all, but to excite a plasma discharge in a gas tube.”),
`
`2026 (“Steinberg’s source coils 111 and sensor coil 143 are not magnetic resonators,
`
`as required by amended claim 1. Further, source coils 111 do not transfer operating
`
`power to sensor coil 143.”).
`
`The Examiner subsequently allowed the amended claims. ’635 FH 2037-
`
`2039. As shown below, however, Kanno not only discloses magnetic resonators
`
`configured to generate magnetic fields with opposing dipole moments but it also
`
`describes using those resonators for wireless power transfer.

`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`C. The Challenged Claims
`Claim 1 is the sole independent claim of the ’635 patent. It recites the wireless
`
`power transfer system in two parts—its components and its operation. Specifically:
`
`[a] a first magnetic resonator;
`
`[b] a second magnetic resonator;
`
`[c] a device magnetic resonator positioned closer to the first source magnetic
`
`resonator;
`
`wherein during operation of the system;
`
`[d] a first current flowing in the first source magnetic resonator generates a
`
`magnetic field which has a first dipole moment;
`
`[e] a second current flowing in the second magnetic resonator generates a
`
`magnetic field, which has a second dipole moment substantially opposite to the
`
`direction of the first dipole moment;
`
`[f] wherein the first and second source magnetic resonators are positioned so
`
`that the second magnetic field at least partially cancels the first magnetic field.
`
`Claims 2-8 depend from claim 1.
`
`D.
`Person of Ordinary Skill in the Art
`A person of ordinary skill in the art (“POSA”) at the time of the purported
`
`invention would have had a Bachelor’s degree in electrical engineering, physics, or
`
`an equivalent field, and at least two years’ industry experience, or equivalent
`
`12
`
`
`
`
`research. Alternatively, a POSA could substitute directly relevant additional
`
`Petition for Inter Partes Review of USP 9,306,635
`
`education for experience, e.g., an advanced degree relating to the design of circuits
`
`using inductive coupling, or an advanced degree in electrical engineering, physics,
`
`or an equivalent field with at least one year of industry experience. Arnold Decl. ¶¶
`
`8-11.
`
`This Petition does not turn on this precise definition, and the claims would be
`
`unpatentable from the perspective of any reasonable POSA. Id. ¶ 12.
`
`E. Claim Construction
`The Challenged Claims are unpatentable under any reasonable construction,
`
`including their plain meaning. Id. ¶ 13. Solely for purposes of this proceeding,
`
`Petitioner adopts the plain meaning and submits that no claim term requires
`
`construction.2
`
`IV. Ground 1: Claims 1-8 Are Anticipated by Kanno
`The ’635 patent describes and claims nothing more than a known wireless
`
`energy transfer system and the physical phenomena of its operation (e.g., magnetic
`
`fields and dipole moments) as dictated by basic physics. As shown below, Kanno
`
`discloses every element of the Challenged Claims arranged in the same way as
`
`
`2 Petitioner reserves the right to argue alternative constructions in other proceedings,
`
`and where such a defense is available, that the claims are indefinite.
`
`13
`
`
`
`
`recited in those claims.

`
`A. Overview of Kanno
`Kanno was filed October 6, 2011 and claims priority to a provisional filed
`
`October 10, 2010. Thus, Kanno is at least §102(e) prior art because it names different
`
`inventors and was filed in the United States before January 26, 2012, the earliest
`
`claimed priority date of the ’635 patent. As discussed below, Kanno teaches the same
`
`solution to the same problem as the ’635 patent.
`
`1. Wireless Power Transmission Unit
`Kanno describes a system for wirelessly transferring power from solar cells
`
`on a building to electronic devices within the building. Kanno 4:62-5:5, 5:16-20.
`
`The primary component of the system is a “wireless power transmission unit” that
`
`transmits power wirelessly “by using coupling between magnetic resonant fields.”
`
`Id.; see also 2:62-67 (“[I]t is therefore an object of the present invention to provide
`
`a wireless power transmission unit that can increase a low output voltage of a power
`
`generating section effectively.”); Arnold Decl. ¶ 40.
`
`Figure 1 below shows the fundamental arrangement for the wireless power
`
`transmission unit. Kanno 6:50-51.
`

`

`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`
`Kanno Fig. 1. The wireless power transmission unit includes “first and second
`
`wireless power transmitting sections 10a and 10b.” Id. 6:52-55. Each wireless power
`
`transmitting section includes: “an oscillator 103”; “a power transmitting antenna
`
`107”; and “a power receiving antenna 109, which receives, by coupling a resonant
`
`magnetic field, at least a part of the RF energy that has been transmitted by the power
`
`transmitting antenna 107.” Id. 6:55-63. The power receiving antennas 109 are
`
`connected in parallel at their outputs and the received power is “combined together
`
`by a combining section 199” and supplied to a load device 133a. Id. 7:35-42;
`
`Arnold Decl. ¶ 41.
`
`A control section 192 controls the phases of the current supplied from the
`
`oscillators 103 which in turn controls the phases of the resonant magnetic fields 195a
`
`and 195b. Kanno 6:64-7:8. The phase difference (θres) between those magnetic
`
`15
`
`
`
`
`fields “is set to fall within the range of 90 to 180 degrees.” Id. 7:4-8. Figure 2(b)
`
`Petition for Inter Partes Review of USP 9,306,635
`
`below shows a waveform diagram of magnetic fields 195a and 195b with a phase
`
`difference of 180 degrees. Id. 7:14-16; Arnold Decl. ¶ 42.
`
`
`
`Kanno Fig. 2(B).
`
`Because of this phase difference, Kanno describes matching the phases of the
`
`received power at the outputs of the power receiving antennas 109 by: adjusting
`
`transmission line lengths between those outputs and the combining section 199
`
`(Figure 1); adding a phase controller at the output of a power receiving antenna 109
`
`(Figure 3); or reversing the output connection of a power receiving antenna 109
`
`(Figure 4). Kanno 7:50-8:20; Arnold Decl. ¶ 44.
`
`Figure 6 below “illustrates an equivalent circuit for antennas in the wireless
`
`power transmitting sections of the present invention.”

`
`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`
`Kanno Fig. 6, 5:46-47. The power transmitting antenna 107 is a “series resonant
`
`circuit” in which “a power transmitting inductor 107a and a first capacitor 107b are
`
`connected together in series.” Id. 10:35-46. The power receiving antenna 109 is a
`
`“parallel resonant circuit” in which “a power receiving inductor 109a” and a second
`
`capacitor 109b are connected in parallel. Id. The power transmitting antenna 107 and
`
`the power receiving antenna 109 are coupled through “magnetic resonant coupling.”
`
`Id. 10:10-34; Arnold Decl. ¶ 45.
`
`2.
`Power Generator
`Figure 7 below shows the fundamental arrangement of the overall wireless
`
`power transfer system (or “power generator”). Id. 11:9-12. The power generator uses
`
`the wireless power transmission unit of Figure 1 with power generating sections 101.
`
`Id. 11:15-23 (“[T]he power generator shown in FIG. 7 has the same configuration as
`
`the wireless power transmission unit shown in FIG. 1” with the addition of power
`
`generating sections 101); see also Fig. 1; Arnold Decl. ¶ 46.
`

`
`
`
`
`
`Petition for Inter Partes Review of USP 9,306,635
`
`
`
`Kanno Fig. 7 (annotated).
`
`Each power generating section 101 is coupled to the wireless power
`
`transmitting antenna 107 of a wireless power transmitting section (10a or 10b in
`
`Figure 1) to form a “power generating unit.” Kanno 11:15-23 (“[E]ach power
`
`generating unit 131a, 131b includes a power generating section (power generating
`
`device) 101 that supplies DC energy to its associated oscillator 103.”); see also
`
`Fig. 1; Arnold Decl. ¶ 47.
`
`As shown in annotated Figure 7 below, power generating unit 131a includes
`
`a first source magnetic resonator (first power transmitting antenna 107, blue) and a
`
`first device magnetic resonator (first power receiving antenna 109, light blue).
`
`Kanno 6:55-63, 11:15-23. The second power generating unit 131b includes a second
`
`source magnetic resonator (second power transmitting antenna 107, green) and a
`
`18
`
`
`
`
`second device magnetic resonator (second power transmitting antenna 109,
`
`Petition for Inter Partes Review of USP 9,306,635
`
`light green). Id.; Arnold Decl. ¶ 48.
`
`
`
`Kanno Fig. 7 (annotated).
`
`The source magnetic resonators are out of phase (the oscillating current in first
`
`power transmitting antenna 107, blue, flows in the opposite direction as the
`
`oscillating current
`
`in second power
`
`transmitting antenna 107, green).
`
`Kanno 6:64-7:16. As a result, the resonators generate opposing magnetic fields 195a
`
`and 195b (purple). Id. 7:25-28 (“[T]he two dotted arrows representing the two
`
`resonant magnetic fields 195a and 195b point mutually opposite directions, which
`
`schematically indicates that their phase difference is 180 degrees.”). The resonators
`
`(power transmitting antennas 107) thus have opposite dipole moments and their
`
`magnetic fields at least partially cancel each other. Id. 5:8-13 (“[L]eakage of
`
`19
`
`
`
`
`unwanted electromagnetic components into the surrounding space … can be
`
`Petition for Inter Partes Review of USP 9,306,635
`
`reduced.”); see also 20:62-21:4 (“If the absolute value of the phase difference …
`
`between the resonant magnetic fields 195a and 195b is … equal to 180 degrees, then
`
`the two resonant magnetic fields will cancel each other, and therefore, leakage of
`
`electromagnetic waves into the surrounding space can be substantially eliminated.”),
`
`Fig. 2(b); Arnold Decl. ¶¶ 49-50.
`
`Figure 9 below shows “a typical application of a power generator including
`
`the wireless power transmission unit of the present invention.” Kanno 11:37-39.
`
`The power generating sections 101 are solar cells that supply power to the wireless
`
`power transmission section 105. Id. 11:39-52. The “power transmitting and power
`
`receiving antennas 107 and 109 … face each other with the wall 111 of the building
`
`200 interposed between them.” Id. 11:52-55. The power received by the power
`
`receiving antennas 109 is “transmitted to devices inside of the building 200 either
`
`through cables or wirelessly.” Id. 12:2-5.

`Kanno describes a real-world implementation of the power generator as
`
`“Example 1” with two power generating units connected in parallel. Kanno
