`Petition for Inter Partes Review
`INTRODUCTION AND STATEMENT OF RELIEF REQUESTED (37
`C.F.R. § 42.22(A))
`
`General Electric Co. D/B/A GE Healthcare (“Petitioner”) petitions for the
`
`I.
`
`
`
`institution of inter partes review of claims 47-80 (the “Challenged Claims”) of
`
`U.S. Patent No. RE45,725 to John P. Mugler, III,, et al (“the ’725 Patent,” attached
`
`as Ex. 1001). USPTO records indicate that the ’725 Patent is assigned to
`
`University of Virginia Patent Foundation (“P.O.”), which is currently asserting the
`
`’725 Patent against Petitioner in a concurrent litigation. See Ex. 1012.
`
`II. MANDATORY NOTICES
`
`A. Real Party-in-Interest
`
`
`
`
`
`General Electric Co. (Petitioner) is the real party-in-interest.
`
`B. Related Matters
`
`P.O. has sued Petitioner in the U.S. District Court for the Western District of
`
`Virginia, alleging infringement of the ’725 Patent (Ex. 1001). UVAPF v. General
`
`Electric Co., No. 3:14-cv-00051-nkm (“GE Litigation”). On October 16, 2015,
`
`P.O. filed a motion for leave “request[ing] that the Court permit UVAPF to file
`
`[an] amended complaint” adding the ’725 Patent. Ex. 1008. On October 19, 2015,
`
`the Court granted P.O.’s motion for leave (Ex. 1011), and P.O. filed an amended
`
`complaint asserting the ’725 Patent against Petitioner. Ex. 1012. Thus, Petitioner
`
`was not “served with a complaint” under § 315(b) until October 19, 2015. See
`
`TRW Automotive US v. Magna Elecs., Inc., IPR2014-00293, Paper No. 18 at 5-11
`
`
`
`-1-
`
`
`
`(P.T.A.B. June 27, 2014) (holding that, “regardless of any prior ‘consent’ by a
`
`Petitioner,” a proposed amended complaint attached to a Patent Owner’s motion
`
`requesting leave to amend a pleading is “not an actual ‘complaint’ within the
`
`meaning of § 315(b).”).
`
`
`
`The ’725 Patent is a continuation of U.S. Patent No. RE44,644 (“the ’644
`
`Patent,” Ex. 1007). In the GE Litigation, P.O. also has asserted the ’644 Patent.
`
`The ’644 Patent is the subject of three instituted inter partes reviews, styled as
`
`General Electric Co. v. University of Virginia Patent Foundation in Case Nos.
`
`IPR2016-00357, IPR2016-00358, and IPR2016-00359 (“’644 IPRs”). The GE
`
`Litigation is stayed until the resolution of the ’644 IPRs.

`
`CERTIFICATION OF GROUNDS FOR STANDING
`
`
`
`- 2 -
`
`
`
`
`
`
`
`Petitioner certifies pursuant to Rule 42.104(a) that the patent for which
`
`review is sought is available for inter partes review and that Petitioner is not
`
`barred or estopped from requesting an inter partes review challenging the patent
`
`claims on the grounds identified in this Petition.
`
`IV. OVERVIEW OF CHALLENGE AND RELIEF REQUESTED
`
`
`
`The Challenged Claims are unpatentable as being anticipated under 35
`
`U.S.C. §§ 102(a),(b) and/or for being obvious under 35 U.S.C. § 103. Specifically:
`
`A. GROUND 1: Claims 47-80 are anticipated under §§ 102(a)
`and/or 102(b) by Mugler et al, “Three-Dimensional T2-
`Weighted Imaging of the Brain Using Very Long Spin-Echo
`Trains,” Proceedings of the International Society for Magnetic
`Resonance in Medicine, Eighth Meeting, April 2000 at 687
`(“Mugler 2000”) (Ex. 1002)
`B. GROUND 2: Claims 47-80 are obvious under § 103(a) over
`Mugler 2000 in view of Mugler, “Overview of MR Imaging
`Pulse Sequences,” Physics of MR Imaging, Vol. 7, No. 4, pp.
`661-697 (Nov. 1999) (“Mugler Overview”) (Ex. 1005)
`C. GROUND 3: Claims 47-80 are obvious under § 103(a) over
`Alsop, “The Sensitivity of Low Flip Angle RARE Imaging,”
`Magnetic Resonance in Medicine, Vol. 37, pp. 176-184
`(“Alsop”) (Ex. 1004) in view of Mugler et al, “Three-
`Dimensional Spin-Echo-Train Proton-Density-Weighted
`Imaging Using Shaped Signal Evolutions,” Proceedings of the
`International Society for Magnetic Resonance in Medicine,
`Seventh Meeting, May 1999 at 1631(“Mugler 1999”) (Ex.
`1003)
`D. GROUND 4: Claims 47-80 are obvious under § 103(a) based
`on Alsop in view of Mugler 1999, further in view of Mugler
`Overview
`
`
`
`
`
`This Petition is supported by the declaration of Dr. Norbert Pelc (Ex. 1009).

`
`
`
`
`
`V. OVERVIEW
`
`A. Technical Background
`
`
`
`Magnetic resonance imaging (MRI) uses magnetic field and radio frequency
`
`(RF) pulses applied to an object, such as anatomical structures in a patient’s body,
`
`to produce a signal that can be processed into images of the object. An MRI scan
`
`uses an ordered combination of RF and gradient pulses, called a pulse sequence,
`
`designed to acquire data to from the image. Ex. 1009 ¶¶ 40-42. There are three
`
`inherent properties of all matter that are used to distinguish between types of
`
`tissues in an MR scan: proton density, T1 relaxation, and T2 relaxation. Because
`
`the values of these three properties are different for various substances within the
`
`body, the difference in values for particular substances may be exploited to
`
`generate contrast to form an image. Id. at ¶¶ 45-46. “Spin-echo” and “fast-spin-
`
`echo” pulse sequences are well known sequences that have an excitation RF pulse
`
`followed by one or more refocusing RF pulses. The pulses are applied at a “flip
`
`angle” relative to the main magnetic field.
`
`B.
`
`The ’725 Patent
`
`(i)
`
`Summary of Alleged Invention of the ’725 Patent
`
`
`
`The Challenged Claims of the ’725 Patent are substantially similar to those
`
`of the ’644 Patent at issue in the ’644 IPRs. See Ex. 1015. Like the ’644 Patent, the
`
`’725 Patent generally relates to spin-echo imaging. See Ex. 1001 at 3:65-4:6. The
`
`
`
`- 4 -
`
`
`
`
`
`’725 Patent explains its purported advancement over the prior art as incorporating
`
`the effect of tissue relaxation in its determination of flip angle values. See, e.g., Ex.
`
`1001 at 3:38-62 (contrasting the prior art, which “derived variable flip-angle series
`
`. . . when T1 and T2 relaxation are neglected,” with “[t]he present invention
`
`method and apparatus” which “explicitly consider the T1 and T2 relaxation times
`
`for the tissues of interest and thereby permit the desired image contrast … .”).
`
`Consideration of T1 and T2 relaxation times occurs as part of a 4-step algorithm
`
`for calculating the flip angles. Ex. 1001 at 10:33-11:14. It is this algorithm for
`
`calculating, or selecting, the flip angles for an MR pulse sequence, which includes
`
`the effects of T1 and T2 relaxation, that the ’725 Patent regards as its advancement
`
`over the prior art. Ex. 1009 ¶ 51-56.
`
`(ii) The Prosecution History
`
`
`
`The ’725 Patent is a continuation of the ’644 Patent, which is a reissue of
`
`U.S. Pat. No. 7,164,268 (“the ’268 Patent”) (Ex. 1013). See Ex. 1001 at 1. Each
`
`claim of the ’268 Patent required a “calculating flip angles” step that includes “i)
`
`selecting values of T1 and T2 relaxation times and selecting proton density,” “ii)
`
`selecting a prescribed time course of the amplitudes and phases of the radio-
`
`frequency magnetic resonance signals . . . .”, and “iii) selecting characteristics of
`
`said contrast-preparation step, said data-acquisition step and a magnetization-
`
`recovery step . . . .” Ex. 1013 at cls. 1-46.
`
`
`
`- 5 -
`
`
`
`
`
`
`
`In contrast, each of the Challenged Claims of the ’725 Patent omits each of
`
`the three “selecting” steps in each claim of the ’268 Patent directed to the disclosed
`
`algorithm for determining flip angles. Ex. 1001 at cls. 47-80.
`
`(iii) Effective Filing Date Of The Challenged Claims
`
`
`
`The ’725 Patent claims the benefit of priority to U.S. Provisional App. No.
`
`60/257,182 (“the ’182 Application”) (Ex. 1014). The priority claim to the ’182
`
`Application is ineffective because the subject matter of the Challenged Claims was
`
`not disclosed in the ’182 Application in the manner required by 35 U.S.C. § 112, ¶
`
`1. See, e.g., SAP America, Inc. v. Pi-Net Int’l, Inc., IPR No. 2014-00414, Paper No.
`
`11 at 11-14 (P.T.A.B. August 18, 2014) (relying on § 112 case law is proper in an
`
`inter partes review to establish effective filing date). It is P.O.’s burden to show
`
`that the ’182 Application provides written description support for the Challenged
`
`Claims. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375,
`
`1378 (Fed.Cir. 2015)(affirming P.T.A.B. that party asserting that a patent is
`
`entitled to the benefit of a provisional filing date has the burden of demonstrating
`
`written description support in the provisional application). To comply with the
`
`written description requirement, the specification “must describe the invention
`
`sufficiently to convey to a person of skill in the art that the patentee had possession
`
`of the claimed invention at the time of the application, i.e., that the patentee
`
`invented what is claimed.” Lizardtech, Inc. v. Earth Resource Mapping, Inc., 424
`
`
`
`- 6 -
`
`
`
`
`
`F.3d 1336, 1345 (Fed Cir. 2005). In particular, the written description must
`
`provide sufficient information to indicate to a person of ordinary skill that the
`
`inventor had possession of the “full scope” of the claims. See, e.g., In re Wertheim,
`
`541 F.2d 257, 262-64 (C.C.P.A. 1976) (emphasis added). “[A]ll the limitations
`
`must appear in the specification” of the priority application, as “[t]he question is
`
`not whether a claimed invention is an obvious variant of that which is disclosed
`
`in the specification.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed.
`
`Cir. 1997) (emphasis added) (expert testimony that claimed subject matter was
`
`“well known” to persons skilled in the art was insufficient to provide written
`
`description support and meant, at best, that the claimed subject matter would have
`
`been obvious to persons skilled in the art). Rather, “one skilled in the art, reading
`
`the original disclosure, must immediately discern the limitation at issue in the
`
`claims.” Purdue Pharma L.P. v. Faulding Inc., 230 F.3d 1320, 1323 (Fed. Cir.
`
`2000). Although the exact terms of the claims need not be used in haec verba to
`
`provide written description, see Eiselstein v. Frank, 52 F.3d 1035, 1038, 34
`
`USPQ2d 1467, 1470 (Fed.Cir.1995), “possession” of an invention can only be
`
`shown by describing the invention with all its claim limitations, even if they are
`
`obvious, and is measured as of the filing date sought. See, e.g., Lockwood, 107
`
`F.3d at 1572. The Challenged Claims are directed to an “invention” that was not
`
`disclosed as being within the inventor’s possession at the time of filing of the ’182
`
`
`
`- 7 -
`
`
`
`
`
`Application. Accordingly, the Challenged Claims are not entitled to the effective
`
`filing date of the ’182 Application.
`
`(A) The Challenged Claims are directed to the results of
`an algorithm for determining flip angles while
`omitting the entirety of the algorithm disclosed by the
`’182 Application for achieving those results
`The ’182 Application discloses that “[o]ur method explicitly considers the
`
`
`
`Tl and T2 relaxation times for the tissues of interest and thereby permits the
`
`desired image contrast to be incorporated into the tissue signal evolutions
`
`corresponding to the long echo train.” Ex. 1014 at 3 (emphasis added). Likewise,
`
`the ’725 Patent states that “[t]he present invention method and apparatus
`
`explicitly consider the T1 and T2 relaxation times for the tissues of interest.”
`
`Ex. 1001 at 3:55-57 (emphasis added). Similarly, the ’182 Application states that
`
`“[t]his invention consists of . . . for selected T1 and T2 relaxation times.” Id. at
`
`4 (emphasis added). Consistent with the requirement of considering relaxation, the
`
`’182 Application provides a four-step algorithm for determining flip angles that
`
`includes, among other steps, selecting “the T1 and T2 relaxation parameters for the
`
`‘target’ tissue.” Ex. 1014 at 6-7. This four-step algorithm is the only guidance the
`
`’182 Application provides on how to select flip angles; no other algorithm is
`
`disclosed. Ex. 1009 ¶¶ 67-68. As all MR pulse sequences necessarily have flip
`
`angle parameters, and the ’182 Application only provides one algorithm for
`
`selecting the flip angle parameters, a person of ordinary skill would understand the
`
`
`
`- 8 -
`
`
`
`
`
`’182 Application to require that flip angles be selected using the four-step
`
`algorithm in order to achieve the described beneficial results. Id. at ¶ 68.
`
`Furthermore, in the ’644 IPRs, UVAPF has relied extensively on the four-step
`
`algorithm as providing support for the claimed range results. Id.
`
`
`
`Each Challenged Claim omits the limitation “selecting values of T1 and T2
`
`relaxation times.” Furthermore, there is no requirement in any Challenged Claim
`
`that Tl and T2 relaxation times for the tissues of interest be considered in any way,
`
`much less explicitly considered. Ex. 1009 ¶ 69. Not only does each Challenged
`
`Claim omit consideration of T1 and T2 relaxation times—which is described as
`
`“the invention” —but each Challenged Claim also omits the entirety of the four-
`
`step algorithm for determining flip angles. Ex. 1009 ¶ 70. This four-step algorithm
`
`for determining, or calculating, the flip angles is the only disclosure in the ’182
`
`Application with respect to how the flip angles are selected. Id. In addition, the
`
`three imaging examples described in the ’182 Application, referred to as Example
`
`Nos. 1-3, were each obtained using flip angles calculated using the four-step
`
`algorithm to perform the image acquisition. Id. However, each Challenged Claim
`
`merely requires that “said flip angle is selected to vary” and covers all ways of
`
`selecting flip angles, whether or not the flip angles are selected using the process
`
`described in the ’182 Application. The claimed requirement that the flip angles
`
`“vary, among a majority of the total number of said refocusing pulses applied
`
`
`
`- 9 -
`
`
`
`
`
`during the echo train, by decreasing to a minimum value and later increasing” is
`
`just a result of the process used to select flip angles. Id. Likewise, obtaining flip
`
`angles corresponding to pulse sequence parameters with an effective echo time that
`
`is “at least twice” is similarly a result of the process used to select the flip angles.
`
`Id. In addition, the claimed “flip angles result[ing] in a reduced power deposition”
`
`is just a result of the process used to select the flip angles. Id.; Ex. 1001 at cl. 47
`
`(emphasis added).
`
`
`
`Claiming only the results of an algorithm while omitting the steps of the
`
`algorithm for achieving the results does not comply with the written description
`
`requirement. In LizardTech, Inc. v. Earth Res. Mapping, Inc., 424 F.3d 1336, 1346
`
`(Fed. Cir. 2005), the patentee disclosed one algorithm for performing a type of
`
`image compression referred to as “a seamless DWT” that included a step of
`
`summing DWT coefficients. The Federal Circuit held that claims directed only to
`
`the disclosed results of the algorithm that omitted the steps of the algorithm for
`
`achieving those results were invalid for lack of written description. See id. at 1344:
`
`The trouble with allowing claim 21 to cover all ways of performing
`DWT-based compression processes that lead to a seamless DWT is
`that there is no support for such a broad claim in the specification.
`The specification provides only a single way of creating a seamless
`DWT, which is by maintaining updated sums of DWT coefficients.
`There is no evidence that the specification contemplates a more
`generic way of creating a seamless array of DWT coefficients.
`
`
`
`- 10 -
`
`
`
`
`
`(emphasis added). Thus, the Federal Circuit held that “the description of one
`
`method for creating a seamless DWT does not entitle the inventor of the ’835
`
`patent to claim any and all means for achieving that objective.” Id. at 1346
`
`(emphasis added). Because the ’182 Application describes only one method of
`
`selecting flip angles—using the four-step algorithm— but the Challenged Claims
`
`cover all methods of selecting flip angles that achieve the claimed results, the
`
`Challenged Claims run afoul of exactly the same written description shortcoming
`
`that resulted in the invalidation of the claims at issue in LizardTech.
`
`
`
`The invalid claimed combination at issue in LizardTech lacked written
`
`description support even though each individual limitation of the claim was
`
`adequately described. See id. at 1346 (rejecting argument that “section 112 requires
`
`only that each individual step in a claimed process be described adequately”
`
`because that approach “would lead to sweeping, overbroad claims because it would
`
`entitle an inventor to a claim scope far greater than what a person of skill in the art
`
`would understand the inventor to possess.”) Similarly, even if P.O. could somehow
`
`show that each limitation of the Challenged Claims is described in the ’182
`
`Application, P.O. cannot show support for its overbroad claims that cover all ways
`
`of selecting flip angles—including ways other than the only way described in the
`
`’182 Application, the four-step algorithm, and including other ways not yet even
`
`
`
`- 11 -
`
`
`
`
`
`conceived. Accordingly, the Challenged Claims lack written description support
`
`because each covers a broader invention not disclosed in the ’182 Application.
`
`
`
`Likewise, the Challenged Claims lack written description support because
`
`the four-step algorithm is the only method provided by the specification for
`
`selecting flip angles and a person of ordinary skill would not understand the named
`
`inventors of the ’182 Application to have invented an MR pulse sequence that uses
`
`flip angles other than those derived according to the four-step algorithm. Ex. 1009
`
`¶¶ 72-74. See ICU Medical, Inc. v. Alaris Medical Systems, Inc., 558 F.3d 1368,
`
`1377 (Fed. Cir. 2009)(applying LizardTech to affirm district court’s grant of
`
`summary judgment that claims directed to a “spikeless” or “spike-optional”
`
`medical device were invalid for lack of written description because the
`
`“specification describes only medical valves with spikes” and “a person of skill in
`
`the art would not understand the inventor . . . to have invented a spikeless medical
`
`valve.”)
`
`(B) The ’182 Application does not describe the “magnetic-
`field gradient pulses” limitation recited by each
`Challenged Claim
`
`
`
`Each of the Challenged Claims recites a “a data-acquisition step” that
`
`comprises “providing magnetic-field gradient pulses that perform at least one of
`
`encoding spatial information into at least one of the radio-frequency magnetic
`
`
`
`- 12 -
`
`
`
`
`
`resonance signals . . . and dephasing transverse magnetization . . . .” Ex. 1001 at
`
`cls. 75, 140, 157-58, and 176-177 (emphasis added).
`
`
`
`First, the ’182 Application does not provide support for the magnetic field
`
`gradient pulses encoding spatial information into “at least one of” the RF magnetic
`
`resonance signals that follow “at least one of” said refocusing radio-frequency
`
`pulses. Ex. 1009 ¶¶ 75-77. The ’182 Application discloses that “[a]ny form of the
`
`applied spatial-encoding gradient waveforms . . . are applicable.” Ex. 1014 at 6.
`
`However, disclosure of applied spatial-encoding gradient waveforms does not
`
`disclose or suggest that spatial information may be encoded into only one of the
`
`RF magnetic resonance signals for only one of the refocusing RF pulses. Ex. 1009
`
`¶¶ 75-77. The plain meaning of the claimed “at least one” limitation encompasses
`
`within its full scope encoding spatial information into only one of the RF magnetic
`
`resonance signals for only one of the refocusing RF pulses. However, a person of
`
`ordinary skill in the art would understand that applied spatial-encoding gradient
`
`waveforms as disclosed by the ’182 Application necessarily encode spatial
`
`information for all of th
