`IN SUPPORT OF PETITION FOR
`INTER PARTES REVIEW OF U.S. PATENT NO. 8,846,112
`
`1
`
`
`
`
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`I, Dr. Edward Lawson, declare that:
`
`QUALIFICATIONS
`
`1.
`
` I am a Professor Emeritus in Pediatrics at Johns Hopkins University.
`
`I have a Bachelor’s Degree from Harvard University and a Medical Degree from
`
`Northwestern University Medical School. I interned in Pediatrics and did a
`
`neonatology fellowship at Children’s Hospital Medical Center, Boston Hospital for
`
`Women and Beth Israel Hospital in Boston, MA. I was a Research Fellow in
`
`pediatrics at Harvard Medical School.
`
`2.
`
`I have practiced neonatology since 1978. During my practice, I held
`
`various leadership and research positions. I have been active in managing
`
`premature, full-term and older infants with hypoxic respiratory failure of many
`
`different etiologies. I have extensive clinical experience with the utilization of
`
`nitric oxide therapy for relief of persistent pulmonary hypertension, BPD and other
`
`disorders.
`
`3.
`
`I was the Chair of the American Lung Association/American Thoracic
`
`Society Research Committee. I am also an active member of many NIH study
`
`sections where grants related to neonatal pulmonary research have been decided.
`
`4.
`
`I am currently the Editor-in-Chief for the Journal of Perinatology (the
`
`Official Journal of the Section on Neonatal Perinatal Medicine of the American
`
`
`

`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`Academy of Pediatrics). I also have experience as an editor for the Fetal and
`
`Neonatal section of the Journal of Pediatrics.
`
`5.
`
`I joined the Johns Hopkins faculty in 1999. At Johns Hopkins I have
`
`served as the Director of the Sutland/Pakula Family Newborn Critical Care Center,
`
`in the Division of Neonatal and Perinatal Medicine. I also served as the Vice Chair
`
`of the Department of Pediatrics at Hopkins Children’s Center.
`
`6.
`
`7.
`
`A copy of my curriculum vitae is attached as Exhibit 1003.
`
`I am not an employee of Praxair Distribution, Inc.; Praxair, Inc.,
`
`NOxBOX Limited or any affiliated company. Rather, I have been engaged in the
`
`present matter to provide my independent analysis of the issues raised in the
`
`above-mentioned inter partes review of U.S. Patent No. 8,846,112 (“the ‘112
`
`Patent”) Ex. 1001. I have received no compensation for this declaration beyond
`
`my normal hourly compensation of $425 for time actually spent studying the
`
`matter, and I will not receive any added compensation based on the outcome of any
`
`proceeding relating to the ‘112 Patent.
`
`8.
`
`Based upon my extensive knowledge and years of experience in this
`
`field, I have an understanding of how inhaled NO was being used for medical
`
`treatment on or before June 30, 2009, as well as the risks and contraindications
`
`associated with its use. My analysis on this matter, as set forth below, is based on
`
`
`
`3
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`my personal experience and what was known, and in fact, considered to be
`
`standard by one skilled in the art prior to June 30, 2009.
`
`9.
`
`I have reviewed and am familiar with the ‘112 Patent. Ex. 1001.
`
`Additionally, I have reviewed the following documents: (1) Ex. 1006, A.
`
`Greenough & A. D. Miller, Neonatal Respiratory Disorders 149, 183–87, 392 (2nd
`
`ed. 2003) (“Greenough”); (2) Ex. 1007, Jaypee, Pediatric & Neonatal Mechanical
`
`Ventilation 148–58 (Praveen Khilnani ed., 1st ed. 2006) (“Jaypee”); and (3) Ex.

`http://www.accessdata.fda.gov/drugsatfda_docs/nda/99/20845_inomax_prntlbl.pdf
`
`(August 9, 2000). (“INOmax Label”). I was already familiar with the concepts and
`
`physiology of iNO and its uses. I have also reviewed the documents cited
`
`elsewhere herein, as well as any documents cited in the declarations I have
`
`submitted or will submit in other inter partes review petitions arising out of my
`
`engagement in this matter. I have also reviewed the prosecution file history for the
`
`‘112 Patent, as well as the other patents on which I have opined in this
`
`engagement, particularly the declarations submitted during prosecution. Based on
`
`the references and my experience and background, I do not agree that INOT22
`
`study provides evidence that the claims are patentable; nor do I agree that the claim
`
`elements were not known. Specifically, as discussed below, the allegedly
`
`
`
`4
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`unknown aspects of the INOT22 study were clearly disclosed by, for example,
`
`Greenough, the INOmax Label, and Jaypee prior to June 30, 2009.
`
`10. My opinions, explained below, are based on my education,
`
`experience, and background in the field discussed above as well as my review of
`
`the references cited above.
`
`BACKGROUND KNOWLEDGE ONE OF SKILL IN THE ART BEFORE
`
`THE ‘112 PATENT
`
`11. The ʼ112 Patent is entitled “Methods of Distributing a Pharmaceutical
`
`Product Comprising Nitric Oxide Gas for Inhalation.” Ex. 1001 at Cover. The
`
`ʼ112 Patent discusses supplying inhaled NO1 (for example, a cylinder of NO gas)
`
`to doctors
`
`along with
`
`information/instructions
`
`regarding dosage
`
`and
`
`contraindications for treatment. Ex. 1001, Abstract. The ʼ112 Patent discusses a
`
`canister of iNO along with information regarding a pre-screening protocol to
`
`determine whether a patient has a condition, such as left ventricular dysfunction
`
`(“LVD”), that could lead to an Adverse Event or Serious Adverse Event such as
`
`pulmonary edema if the patient is treated with inhaled NO. See, e.g., Ex. 1001 at
`
`1:50-56; 9:24-33; 12:49-61. It also explains that if a patient is determined to have
`
`LVD, he or she is at risk of suffering a Serious Adverse Event such as pulmonary
`
`
`1 “Inhaled nitric oxide” is abbreviated as “iNO.”
`
`
`
`5
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`edema2 upon treatment with iNO. Ex. 1001 at Abstract; 1:50-56. The ’112 Patent
`
`suggests that these patients should be “possibly exclude[d] from treatment.” Ex.
`
`1001 at 1:53-54.
`
`12. Claim 1 of the ’112 Patent is representative:
`
`A method of providing pharmaceutically acceptable nitric oxide gas,
`the method comprising:
`
`obtaining a cylinder containing compressed nitric oxide gas in the
`form of a gaseous blend of nitric oxide and nitrogen;
`supplying the cylinder containing compressed nitric oxide gas to a
`medical provider responsible for treating neonates who have hypoxic
`respiratory failure, including some who do not have left ventricular
`dysfunction;
`providing to the medical provider (i) information that a recommended
`dose of inhaled nitric oxide gas for treatment of neonates with
`hypoxic respiratory failure is 20 ppm nitric oxide
`and (ii) information that, in patients with pre-existing left ventricular
`dysfunction, inhaled nitric oxide may increase pulmonary capillary
`wedge pressure (PCWP), leading to pulmonary edema, the
`information of (ii) being sufficient to cause a medical provider
`considering inhaled nitric oxide treatment for a plurality of neonatal
`patients who (a) are suffering from a condition for which inhaled
`nitric oxide is indicated, and (b) have pre-existing left ventricular
`dysfunction, to elect to avoid treating one or more of the plurality of
`patients with inhaled nitric oxide in order to avoid putting the one or
`more patients at risk of pulmonary edema.
`Ex. 1001 at 14:28-52.
`13.
`In order to determine if a patient has a left ventricular dysfunction, a
`
`practitioner may measure the pulmonary capillary wedge pressure (“wedge
`

`
`
`

`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`pressure”) or perform an echocardiograph.3 Id. I am familiar with these protocols
`
`and treatments, and was an expert in this area prior to the priority date of the ‘112
`
`Patent on June 30, 2009. This expertise comes from the field of pediatric
`
`cardiology and pulmonary hypertension where the differentiation between pre-
`
`capillary pulmonary hypertension that includes normal wedge pressure and post-
`
`capillary pulmonary hypertension is a key distinction in this field. In fact, unless
`
`the patient has a left heart obstruction or dysfunction which is causing pulmonary
`
`venous hypertension, the wedge pressure is normal. Given that these two types of
`
`pulmonary hypertension classifications react differently to therapeutic modalities,
`
`it becomes exceedingly important to decipher between the two classifications.
`
`This is well established in the pulmonary hypertension field, and lead to the
`
`separation and distinct diagnostic classification of these two types of pulmonary
`
`hypertension many years ago. See e.g., Ex. 1008, Widlitz, et al., Pulmonary
`
`arterial hypertension in children, 21 Eur.Respir. J. 155-176 at 156-57 (2003)
`
`(“Widlitz”); Ex. 1007, Jaypee at 156. Although the clinical classifications apply to
`
`pulmonary hypertension generally, the teachings are equally applicable to the
`
`context of pulmonary hypertension treated with inhaled NO and the effect of left
`
`ventricular heart disease.
`
`3 Echocardiography is the use of ultrasound waves to investigate the actions of
`
`the heart.
`
`
`
`7
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`14. Pulmonary arterial hypertension is characterized by an increased
`
`pulmonary artery pressure and increased pulmonary vascular resistance. See, e.g.
`
`Ex. 1001 at 3:18-23. Nitric oxide is a selective pulmonary vasodilator that
`
`increases the partial pressure of arterial oxygen by dilating pulmonary vessels in
`
`ventilated areas of the lung, and directing blood flow away from areas with low
`
`ventilation/perfusion ratios toward regions with normal ratios. Ex. 1001 at 3:32-
`
`39. Before June 30, 2009, it was known to those of skill in the art that nitric oxide
`
`may be used as a vasodilator.4 See, e.g. Ex. 1007, Jaypee at 148. Nitric oxide is a
`
`gaseous chemical compound used to treat patients with severe breathing problems.
`
`Nitric oxide is particularly useful in the treatment of pulmonary hypertension, as
`
`inhaled nitric oxide can lead to selective pulmonary vasodilation, therefore
`
`reducing pulmonary vascular resistance, decreasing pulmonary arterial pressure,
`
`and easing right ventricular afterload. Ex. 1008, Widlitz at 156-57, 161. Once
`
`inhaled, the nitric oxide diffuses across alveolar membranes to closely adjacent
`
`vessels. This activates guanylate cyclase in pulmonary smooth muscle cells, which
`
`in turn increases intracellular cyclic guanosine monophosphate (cGMP) production
`
`in the cells. The increased cGMP causes pulmonary smooth muscles to relax
`
`resulting in pulmonary arteriole dilation. Ex. 1008, Widlitz at 169-170.
`
`4 Vasodilation is the widening of blood vessel that results from relaxation of
`
`smooth muscle cells within the vessel walls.
`
`
`

`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`15. While not all patients and not all conditions are responsive to
`
`treatment with inhaled NO, pulmonary hypertension, specifically persistent
`
`pulmonary hypertension of the newborn (PPHN), is a condition that may be treated
`
`with inhaled NO. See, e.g. Ex. 1007, Jaypee at 149-150. Twenty parts per million
`
`of inhaled NO is approved by the FDA to treat neonatal hypoxic respiratory
`
`failure5 and has been approved since 2000. Id.; see also Ex. 1010, Center for Drug
`
`Evaluation and Research, Application Number: NDA 20845, INOMAX, Final
`
`Printed
`
`Labeling,
`
`available
`
`at
`
`http://www.accessdata.fda.gov/drugsatfda_docs/nda/99/20845_inomax_prntlbl.pdf
`
`(August 9, 2000) at 6 (“INOmax label”). It is indeed the only pathology for which
`
`
`5 Hypoxic respiratory failure and hypoxemic respiratory failure, conditions where
`
`the cells of the body do not have enough oxygen, may be caused by pulmonary
`
`hypertension. Therefore, treatment of pulmonary hypertension would also
`
`result in treatment of hypoxic respiratory failure caused by pulmonary
`
`hypertension. Hypoxic respiratory failure may lead to hypoxia (a condition
`
`characterized by low oxygen in all organs; where the tissue does not have
`
`enough oxygen). Treatment of hypoxia may be understood to include treatment
`
`of hypoxic respiratory failure, as the hypoxia is the condition that causes harm
`
`to the patient.
`

`
`inhaled nitric oxide has been approved in the United States. 6 Id. While inhaled
`
`NO certainly has its therapeutic benefits, experienced practitioners are also aware
`
`of a few undesirable side effects and potential complications in certain patients.
`
`One such well-known negative reaction is NO in patients with left ventricular
`
`dysfunction. In these particular patients, inhaled NO can reduce pulmonary
`
`vascular resistance, decreasing the afterload to the right heart, and ultimately
`
`improving right heart output and venous return to the left ventricle. In a poorly
`
`functioning left ventricle, pulmonary edema can occur. Thus, practitioners
`
`thoroughly evaluate their patients prior to treatment, and exclude patients from NO
`
`therapy upon determination of left ventricular dysfunction See, e.g., Ex. 1011,
`
`Pilbeam, Mechanical Ventilation, Special Techniques in Mechanical Ventilation, §
`
`4: Nitric Oxide, (4th ed. 2006) (“Pilbeam”) at 4-6. Such examinations were
`
`commonly done prior to June 30, 2009. Id.
`
`
`6 INOmax, in conjunction with ventilatory support and other appropriate agents,
`
`is indicated for the treatment of term and near-term (>34 weeks) neonates with
`
`hypoxic respiratory failure associated with clinical or echocardiographic
`
`evidence of pulmonary hypertension, where it improves oxygenation and
`
`reduces the need for extracorporeal oxygenation. Ex. 1010 at 4; see also Ex.
`
`1001 at 3:34-52.
`
`
`
`10
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`16. Before June 30, 2009, it was known that, in addition to systolic and
`
`diastolic left ventricular dysfunction, any obstruction to the pulmonary venous
`
`flow, or lesions that may increase pulmonary venous pressure (such as obstructed
`
`pulmonary venous return, mitral stenosis7 or insufficiency, etc.) increase the risk of
`
`a patient suffering a serious adverse event upon treatment with inhaled NO. See,
`
`e.g. Ex. 1007, Jaypee at 151-54. Furthermore, it was also known that NO may not
`
`be beneficial in patients with a high degree of structural pulmonary abnormalities,
`
`such as hypoplasia, as they interfere with the action of the gas.
`
`17. As part of the general medical practice before June 30, 2009, doctors
`
`implemented a clinical diagnostic procedure to assess patient conditions, treatment
`
`options, and potential risks from any potential treatment. First, doctors would
`
`assess the condition of the patient to see if the patient had a condition likely to be
`
`helped by inhaled NO, such as pulmonary hypertension. Second, doctors would
`
`assess whether inhaled NO would likely trigger adverse events in the patient. This
`
`process was performed for all patients. As is clear from the studies which include
`
`numerous patients, one skilled in the art would have understood that a process for
`
`selecting a patient to be treated, or a method of treatment, could be applied to one
`
`7 Mitral stenosis is a condition where the mitral valve, which separates the upper
`
`and lower chambers on the left side of the heart, does not open fully, restricting
`
`blood flow.
`
`
`
`11
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`patient, or to a plurality of patients. See generally Ex. 1006, Greenough, Ex. 1007
`
`Jaypee (disclosing studies
`
`treating multiple patients with
`
`inhaled NO).
`
`Additionally, as Greenough and Jaypee both disclose diagnostic processes for
`
`determining whether a patient should be treated with iNO, one skilled in the art
`
`would understand that multiple patients may be tested and/or treated (e.g. a single
`
`test may have multiple outcomes: either, a patient is a candidate for treatment, or a
`
`patient is not). Additionally, the INOmax label discloses that clinical trials
`
`identified a plurality of patients to be treated with 20 ppm iNO. Ex. 1010 at 2-3.
`
`18. Doctors who were considering prescribing inhaled NO prior to June
`
`30, 2009, like today, would not do so for patients at risk of adverse events or
`
`serious adverse events.
`
`19.
`
`It was a well-known clinical practice on or before June 30, 2009, to
`
`suggest an echocardiogram before administering inhaled NO. Indeed, before June
`
`30, 2009, my team followed this practice before starting nitric oxide, and the
`
`intensive care or neonatology specialists consistently confirmed that it was done
`
`before treatment. We even often assessed the efficacy by echocardiography
`
`through the evaluation of pulmonary pressure, right ventricular anatomy and
`
`
`
`12
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`function as well as shunt8 direction through the ductus arteriosus and the foramen
`
`ovale.
`
`20. Additionally, wedge pressure over 20 mm Hg is a physiological
`
`indicator of conditions that increases risk for patients if they were to receive
`
`treatment with inhaled NO, including left heart dysfunction.9 As was known in the
`
`art prior to June 30, 2009, wedge pressure can be measured by inserting a
`
`pulmonary catheter with an inflated balloon into a small pulmonary arterial branch
`
`8 A cardiovascular shunt is a diversion of the blood flow through an anomalous
`
`opening from the left side of the heart to the right side (from the systemic to the
`
`pulmonary circulation), or from the right side to the left side (from the
`
`pulmonary to the systemic circulation).
`
`9 Wedge pressure is referred to in the literature as pulmonary capillary wedge
`
`pressure (“PCWP”), pulmonary arterial wedge pressure (“PAWP”), or merely
`
`“wedge.” See, e.g., Ex. 1012, M. Hoeper, et al., Definitions and Diagnosis of
`
`Pulmonary Hypertension 62:25 J. of the American College of Cardiology D44
`
`(2013) (“Hoeper”) (noting that pulmonary capillary wedge pressure, pulmonary
`
`arterial wedge pressure, wedge pressure, and wedge are all used to refer to the
`
`same concept and also noting that “wedge” and “wedge pressure” are
`
`commonly used in daily clinical practice, even in non-English speaking
`
`countries).
`
`
`
`13
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`(e.g., a Swan-Ganz catheter). See, e.g., Ex. 1013, Royster, et al., Differences in
`
`Pulmonary Artery Wedge Pressures Obtained by Balloon Inflation Versus
`
`Impaction Techniques, 61 Anesthesiology, 339 – 341 (1984) (“Royster”); see also,
`
`Ex. 1014, Goyal et al., Efficacy of nitroglycerin inhalation in reducing pulmonary
`
`arterial hypertension in children with congenital heart disease, British Journal of
`
`Anaesthesia, 97(2): 208-14 (2006) (“Goyal”) at 209, col. 1, lines 16-20 (showing
`
`measurement of wedge pressure in infants and other children). A rise in wedge
`
`pressure upon treatment with inhaled NO suggests left ventricular dysfunction.
`
`One skilled in the art would have known prior to June 30, 2009, that older children
`
`and adults could have wedge pressure measured with a catheter. While not
`
`typically performed in neonates, one skilled in the art would have known to
`
`measure wedge pressure with a catheter in emergency situations.
`
`21. Before June 30, 2009, it was well-known that wedge pressure could
`
`also be determined through extrapolation based on information gained through
`
`echocardiography. See, e.g., Ex. 1015, Pozzoli, et al., Non-Invasive Estimation of
`
`Left Ventricular Filling Pressures by Doppler Echocardiography, 3 Eur J
`
`Echocardiogr., 3:75-79 (2002) (“Pozzoli”). Wedge pressure may be extrapolated
`
`by the physician in his/her mind from echocardiographic information to identify
`
`whether left heart dysfunction exists and, concomitantly, that physiologically a
`
`wedge pressure exists over a certain value. A pediatric cardiologist with skill and
`
`
`
`14
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`extensive experience with echocardiography would be able to extrapolate wedge
`
`pressure with accuracy to be of use in making a diagnosis or determining whether
`
`the patient in question has a condition such as left ventricular dysfunction that
`
`would require assessment of the risks of treatment and likely contraindicate
`
`treatment with inhaled NO. Even with such skill, a precisely accurate numerical
`
`value will not be reached, only an estimate.
`
`22. As part of regular clinical practice before June 30, 2009, patients not
`
`at risk of adverse events such as pulmonary edema were treated with inhaled NO,
`
`and patients that revealed risk factors during echocardiography, measurement of
`
`wedge pressure, blood gas level, or other clinical assessment were not treated,
`
`assuming the risk of harm to the patient outweighed the potential benefits of
`
`treatment. If the diagnostic results were unclear, or if a potential benefit was
`
`expected, as part of the diagnostic process, one skilled in the art would have known
`
`to administer inhaled NO as a test to see how a patient would react to the drug and
`
`to determine whether a patient had left ventricular dysfunction. Such a patient
`
`would have been carefully evaluated
`
`through
`
`regular and
`
`repeated
`
`echocardiography and clinical evaluation while the test inhaled NO was
`
`administered. If the patient responded in such a way as to suggest that he or she
`
`had left ventricular dysfunction, full treatment with inhaled NO would not have
`
`been prescribed, and the test treatment would have been stopped. All physicians
`
`
`
`15
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`have a basic understanding of negative side effects, and one skilled in the art would
`
`have known not to administer inhaled NO if it would cause harm to the patient that
`
`outweighed the benefits of treatment.
`
`Claim Interpretation
`
`23.
`
`I understand that, for purposes of my analysis, the terms and phrases
`
`appearing in a patent claim should be interpreted according to their “broadest
`
`reasonable construction in light of the specification of the patent in which it
`
`appears.” 37 C.F.R. § 42.100(b). I further understand that the words of the claims
`
`should be given their plain meaning unless that meaning is inconsistent with the
`
`patent specification. I also understand that the words of the claims should be
`
`interpreted as they would have been interpreted by a person of ordinary skill in the
`
`art at the time of the invention was made (not today). I understand that the Board
`
`previously construed the claim phrase “term or near-term neonate” to mean “an
`
`infant aged 1 month or younger born between around 37 and 40 weeks gestation or
`
`greater than around 34 weeks gestation” to a person of ordinary skill in the art. For
`
`the other claim terms in the ‘112 Patent, I applied the plain and ordinary meaning
`
`of all the other terms used in the claims of the ‘112 Patent as those terms would
`
`have been known to one of ordinary skill in the art. For my analysis, I was
`
`instructed to use June 30, 2009, as the point in time for claim interpretation
`
`purposes.
`

`
`16
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`Level of Skill in the Art
`
`24.
`
`In my opinion, a person of ordinary skill in the art would be a
`
`neonatologist or pediatric cardiologist with experience treating neonatal heart and
`
`lung disease and have experience prescribing inhaled NO before June 30, 2009. I
`
`understand that a person of ordinary skill in the art is a hypothetical person who is
`
`presumed to be aware of all pertinent art, thinks along conventional wisdom in the
`
`art, and is a person of ordinary creativity. A person of ordinary skill in the art of
`
`treatment of patients with inhaled NO would have had knowledge of the scientific
`
`literature concerning administration of inhaled NO, including contraindications and
`
`risks as of June 30, 2009. Such a person of ordinary skill in the art would have had
`
`knowledge of the scientific literature related to pulmonary hypertension and
`
`hypoxic respiratory failure. The person of ordinary skill in the art would also have
`
`extensive knowledge and experience with echocardiography. A person of ordinary
`
`skill in the art would have known how to research the scientific literature regarding
`
`the use of inhaled NO. Typically, a person of ordinary skill in the art would be an
`
`experienced neonatologist, pediatric cardiologist, pediatric pulmonologist or
`
`pediatric intensivist.
`

`
`INOmax LABEL AND GREENOUGH IN VIEW OF JAYPEE
`
`
`

`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`26. The ‘112 Patent contains a discussion of the FDA approval for sale of
`
`a product called INOmax®. See generally Ex. 1001 at 3:34-4:22. As part of this
`
`FDA approval, the ’112 Patent discusses certain approved “prescribing information
`
`for INOmax®” that was “in effect in 2009.” Ex. 1001 at 3:45-47. The reference I
`
`refer to as the INOmax label contains this prescribing information. See Ex. 1014.
`
`This reference was submitted to the FDA in 1999, and published in 2000. Thus,
`
`INOmax label was published and available several years before the June 30, 2009
`
`earliest priority date of the ’112 Patent.
`
`27.
`
`In general,
`
`the INOmax
`
`label reference contains prescribing
`
`information that was distributed to medical providers purchasing and using
`
`INOmax® branded iNO gas for therapy. It describes INOmax as “a drug
`
`administered by inhalation” whose active substance is nitric oxide. Ex. 1010 at 1.
`
`INOmax label describes that “INOmax is a gaseous blend of nitric oxide (0.8%)
`
`and nitrogen (99.2%).” Ex. 1010 at 1. It also states that INOmax is “supplied in
`
`aluminum cylinders” of varying sizes and concentrations. Ex. 1010 at 1, 6-7.
`
`Consistent with the discussion above, the INOmax label informed medical
`
`providers that “nitric oxide produces pulmonary vasodilation” and can be used to
`
`treat neonates with PPHN to improve oxygenation. Ex. 1010 at. 1.
`
`28. The INOmax label reference contains “prescribing information” that
`
`was given to medical providers responsible for treating those individuals to whom
`
`
`
`18
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`INOmax label is directed - that is, neonates who have hypoxic respiratory failure.
`
`See Ex. 1010 at 4 (iNO indicated for treatment of “neonates with hypoxic
`
`respiratory failure”). The INOmax label does not indicate that a practitioner should
`
`determine if such neonates do or do not have LVD and therefore discloses treating
`
`neonates with hypoxic respiratory failure but without LVD. Ex. 1010 at 4. A
`
`person of skill in the art reading the INOmax label reference understands that it
`
`discloses a protocol (or method) for administering nitric oxide gas, and that the
`
`protocol information contained in the INOmax label is provided to medical
`
`providers along with cylinders of nitric oxide gas to educate the providers as to the
`
`use of the nitric oxide gas.
`
`29. The INOmax label reference therefore discloses providing cylinders of
`
`a gaseous blend of nitric oxide and nitrogen to medical providers who will be
`
`treating patients with the drug. Ex. 1010 at 1. Further, the INOmax label reference
`
`discloses that iNO is indicated for treatment of term and near-term neonates with
`
`hypoxic respiratory failure, meaning that the information contained therein is
`
`provided to medical providers who will be treating such patients.
`
`30. The INOmax label reference contains an “Administration” section that
`
`discusses FDA-approved delivery mechanisms. Ex. 1010 at 6. This section states
`
`that “[t]he nitric oxide delivery systems used in the clinical trials provided
`
`operator-determined concentrations of nitric oxide in the breathing gas, and the
`
`
`
`19
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`concentration was constant throughout the respiratory cycle.” Ex. 1010 at 6. To a
`
`person of skill in the art, this passage (and the rest of the “Administration” section)
`
`discloses a device that delivers nitric oxide gas into an inspiratory limb of a
`
`breathing circuit.” Since the INOmax label reference mandates such delivery
`
`devices for those medical providers wishing to treat neonates with nitric oxide, it
`
`discloses both obtaining such a device and supplying such a device to the medical
`
`provider.
`
`31. The INOmax label reference also contains “INDICATIONS” and
`
`“CONTRAINDICATIONS” sections. Ex. 1010 at 4. The “INDICATIONS”
`
`section contains information communicated to medical providers to explain the
`
`characteristics of neonatal patients indicated for treatment. Ex. 1010 at 4.
`
`“CONTRAINDICATIONS” contains
`
`information communicated
`
`to medical
`
`providers to explain situations in which inhaled nitric oxide should not be used for
`
`treatment of neonates. Ex. 1010 at 4. Contraindications are indicative of the
`
`risk/benefit analysis that must be undertaken in order to decide to treat or not treat
`
`infants with iNO. There are two types of contraindications: absolute and relative.
`
`Absolute contraindications mean that a patient showing the contraindication must
`
`be excluded from treatment. Relative contraindications provide information that
`
`patients expressing the contraindicated condition should be treated cautiously and
`
`if one skilled in the art does decide to begin treatment, if negative effects occur,
`
`
`
`20
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`treatment should be stopped. The contraindications on the INOmax label appear to
`
`be relative contraindications.
`
`32. A person of skill
`
`in
`
`the art would understand
`
`that
`
`the
`
`“INDICATIONS” and “CONTRAINDICATIONS” sections contain the iNO
`
`indications and contraindications approved by the FDA. However, a person of
`
`skill in the art would also understand that the INOmax label reference more
`
`generally discloses providing information to medical providers regarding when to
`
`use iNO and when not to use iNO. Thus, as additional indications and
`
`contraindications become known, the INOmax label reference suggests to those of
`
`skill in the art that those additional indications and contraindications would have
`
`been provided to medical providers.
`
`33. The INOmax label states that “[t]he recommended dose of INOmax is
`
`20 ppm.” Ex. 1010 at 6. Since the INOmax label reference discloses that INOmax
`
`is “indicated for the treatment of term and near-term (>34 weeks) neonates with
`
`hypoxic respiratory failure…” (Ex. 1010 at 4, emphasis added), it discloses
`
`providing a medical provider with information that a recommended dose of inhaled
`
`nitric oxide gas for treatment of hypoxic respiratory failure is 20 ppm nitric oxide.
`
`34. The INOmax label further discloses that the determination of whether
`
`a neonate has hypoxic respiratory failure can be based on a diagnostic process in
`
`the form of “echocardiographic evidence of pulmonary hypertension.” Ex. 1010 at
`
`
`
`21
`
`
`
`Declaration of Dr. Edward Lawson Regarding U.S. Patent No. 8,846,112
`
`4. Accordingly, the INOmax label discloses
