`
`I have reviewed and understand the Grangaud thesis in French and English (Ex. 1002 and
`
`1003), the Massonet thesis in French and English (Ex. 1004 and 1005), the six Massonet
`
`et al. journal articles in French and English (Exs. 1008-1019), the three Dowling et al.

`
`Patent No.(“USPAT”) 5,310,764 (Ex. 1021), and the description of those publications in
`
`the Petition for Inter Partes Review and think each description set forth in Sections
`
`III(C), IV, and V accurately summarizes the disclosure of the relevant Exhibit.
`
`16.
`
`I have reviewed and understand the claim charts in the Petition for Inter Partes Review,
`
`which claims charts are a condensed version of the claims charts in this Declaration. In
`
`my opinion, a person of ordinary skill in the art would agree that each chart identifies and
`
`discusses representative subject matter from the Exhibits cited in a given claims chart and
`
`(i) teaches each and every claim limitation of claims 1, 3, and 8-27 of the’533 patent as to
`
`the claims charts for Ground 1 in Cyan.IPR.One and in Cyan.IPRTwo (see Claims
`
`Charts for claims 25 and 27 for more detail on the absence of astaxanthin in the brain and

`
`spinal cord), and (ii) renders obvious each of claims 1-27 of the’533 patent as to the
`
`claims charts for Ground 2 in Cyan.IPR.One and in Cyan.IPRTwo.
`
`“Cyan.IPR.One” refers to the Petition for Inter Partes Review filed by Cyanotech to
`
`challenge USPAT 5,527,533 andthat cites Grangaud’s thesis (Ex. 1002) as the base
`
`reference in Ground 1 thereof. “Cyan.IPRTwo” refers to the Petition for Inter Partes
`
`Review filed by Cyanotech to challenge USPAT 5,527,533 and that cites Massonet’s
`
`thesis (Ex. 1004) as the base reference in Ground 1 thereof.
`
`In my opinion, a person of ordinary skill in the art would find the Grangaud thesis, the
`
`Massonet thesis, the Massonet et al. journal articles, the Dowling et al. journal articles,
`
`and USPAT 5,310,764 recited in the Exhibits List of Cyan.IPR.One and of
`
`Cyan.IPRTwoto be enabling disclosures of the subject matter each discusses.
`
`After searching on the terms “astaxanthin” or “vitamin A” in Chemical Abstracts, for
`
`instance,a diligent searcher would have easily been able to locate and retrieve the cited
`
`publications prior to the Critical Date, determine the author’s name, and search on the
`

`
`thesis (Ex. 1004), or any of the journal articles in the Exhibits List of Cyan.IPR.One or

`
`The words “treating”, “damage”, “injury”, and “disease” have commonly accepted
`
`meanings in the field of ‘533 patent (i.e., the pharmaceutical/medical arts) with regard to
`
`“treating an individual suffering from” damage, injury, or disease. Stedman’s Medical
`
`Dictionary, 28th Edition (2006) (Philadelphia, Wolters Kluwer Health ), attached as Ex.
`
`1040, provides definitions appropriate for the ‘533 patent of the terms “treating”,
`
`“damage”, “injury”, and “disease”:
`
`“Treating” means “To manage a disease by medicinal, surgical, or other measures, to
`
`care for a patient medically or surgically.”.
`
`“Damage” means “Harm, diminution, or destruction of an organ, body part, system, or
`
`fimction”
`
`“Injury” means “1. The damage or wound of trauma. 2. Lesion.” .
`
`“Disease” means a “1. An interruption, cessation, or disorder of a body, system, or organ
`
`structure or function. SYN: illness, morbus, sickness. 2. A morbid entity ordinarily
`
`characterized by two or more of the following criteria: recognized etiologic agent(s),
`
`identifiable group of signs and symptoms, or consistent anatomic alterations”.
`
`Substantially similar definitions for such terms are found in other medical dictionaries,
`
`such as Dorland’sMedical Dictionary (Elsevier).
`
`21.
`
`22.
`
`There are two classes of carotenoids: xanthophylls (e.g, lutein, zeaxanthin, canthaxanthin,
`
`and astaxanthin), and other carotenes (e. g., (x-, [5-, and y-carotene). See attached Ex. 1032
`
`(molecular skeletons of xanthophylls and B-carotene). Xanthophylls lutein, zeaxanthin, and
`
`astaxanthin are much stronger antioxidants than or-, [5-, and y-carotenes and other carotenes.
`
`Before explaining in detail how Grangaud and Massonet performed and published the same
`
`methods as claimed in the ‘533 patent decades before the Critical Date, I first point out where
`
`the ‘533 patent is scientifically in error:
`
`Today, almost two decades after the Critical Date, there is no evidence that astaxanthin is
`
`transported into, much less accumulates, in the brain and spinal cord, or in any part of the
`
`central nervous system other than the retina. If astaxanthin accumulated in the brain and
`
`Page 6 of 197
`
`
`
`FJ. Schweigert Declaration 26 June 2013
`
`Cyan.|PR.One and Cyan.|PR.Two
`
`23.
`
`24.
`
`25.
`
`spinal cord, those organs would be pigmented, just as the macula luteain the human retina is
`
`pigmented by the xanthophylls lutein and zeaxanthin, and the corpus luteum in the human
`
`ovary is pigmented by the carotene B-carotene.
`
`The statement in the ‘533 patent that “In addition, astaxanthin has a protective effect on
`
`the central nervous system in general, especially damage to the brain and spinal cord caused
`
`by free radicals.” (Ex. 1001, 14:60-62), has no support in the ‘533 patent (including the file
`
`history thereof)as to the brain and spinal cord, is scientifically erroneous,and cannot be
`
`supported even today (excluding damage to the retina, embryologically, the retina is an
`
`outgrowth of the developing brain, and is therefore is part of the central nervous system).
`
`Therefore, claims 25 and 27 of the ‘533 patent are scientifically erroneous.
`
`Astaxanthin is one of the strongest antioxidants known, in addition to benefiting from the
`
`antioxidant properties of astaxanthin, in the rat retina astaxanthin is converted into vitamin
`
`A(Exs. 1008 and 1010), an essential vitamin.
`
`Transport of astaxanthin from the bloodstream into a tissue requires specialized “binding
`
`proteins” that are present in the retina and a few other animal tissues. Suppression of free
`
`radicals necessarily occurs if astaxanthin is present in animal tissue that contains free
`
`radicals, such as retinal tissue exposed to bright light. Irradiating the retina with bright light
`
`creates excited states of oxygen that characterize peroxyl radicals (R000) andsinglet oxygen
`
`(102) radicals.
`
`Any administration of astaxanthin (other than topical) necessarily results in blood-based
`
`transport of astaxanthin to the retina. The only blood-based access to the eye in vertebrates
`
`is through the retinal and uveal capillary networks that service the retina (including the
`
`retinal pigment epithelium (“RPE”)), and the iris and ciliary body, respectively. Retinal
`
`tissue contains binding proteins that preferentially transport xamhophyll carotenoids, like
`
`lutein, zeaxanthin, canthaxanthin, and astaxanthin, from the retinal capillary network into
`
`retinal tissue, but disfavor transport into retinal tissue of carotene carotenoids, like B-
`
`carotene. Transport of astaxanthin in the bloodstreamrequires specialized “binding
`
`proteins”. Transport of astaxanthin from the bloodstream into a tissue,and accumulation of
`
`astaxanthin in a given type of tissue, requires specialized “binding proteins” that are present
`
`in some, but not all, animal tissue.

`
`Astaxanthin’s inherent mode of action in vertebrate tissue, including retinal tissue, is as a
`
`strong antioxidant and free radical scavenger. Suppression of free radicals, such as peroxyl
`
`and singlet oxygen radicals, and offree radical-induced damage necessarily occurs if
`
`astaxanthin is present in animal tissue that contains free radicals, such as retinal tissue
`
`exposed to bright light.
`
`Xerophthalmia (“dry eye disease”) is the first plainly visible sign of vitamin A deficiency in
`
`rats (symptoms of “night blindness” precede visible signs of xerophthalmia). Xerophthalmia
`
`is secondary to retinal damage, injury, and disease, i.e., retinal damage, injury, and disease
`
`from vitamin A deficiency occurs first (and causes night blindness), then xerophthalmia
`
`manifests at a later stage in the cornea and surrounding areas.
`
`Xerophthalmia is caused by severe vitamin A deficiency. Rats and other vertebrates become
`
`diseased, go blind, and die from continued vitamin A deficiency.
`
`Infliction of vitamin A
`
`deficiency is an injury and causes stunted growth as well as retinal, corneal, and other injury
`
`and diseases.
`
`The layered structure of the retina is shown in Ex. 1032. “Inner” retinal layers refer to layers
`
`closer to the center of the ocular globe. “Outer” retinal layers refer to layers closer to the
`
`sclera (outer surface) of the ocular globe. The retina is largely comprised of various types of
`
`neurons, e.g., ganglion, photoreceptor rods, and photoreceptor cones.
`
`Although photoreceptor cells are one of the “bottom” or “outer” layers of the retina,
`
`photoreceptor cell membranes are especially vulnerable to oxidation, due to an unusual
`
`combination of conditions: a high concentration of oxygen and mitochondria, the presence of
`
`light energy, and a high proportion of polyunsaturated fatty acids (“PUFA”) in
`
`theirmembranes. In general, the potential for free radical-induced cellular damage may be
`
`greater in the retina than in any other tissue because the transparency of ocular structures
`
`allows light-induced generation of free radicals (especially peroxyl radicals of PUFAs)in
`
`addition to free radicals produced by normal oxidative metabolism.
`
`31.
`
`All oxygen-consuming tissues produce small amounts of highly reactive free radicals by
`
`univalent reduction of oxygen, an alternative pathway of oxygen reduction through the
`
`cytochrome system. The high density of mitochondria (which use oxygen in synthesizing
`
`ATP, but create free radicals when oxygen is prematurely reduced) in the photoreceptor cells
`
`Page 8 of 197
`
`
`
`F].
`
`Schweigert Declaration 26 June 2013
`
`Cyan.|PR.One and Cyan.|PR.Two
`
`increases the production of free radicals. Free radical production increases dramatically
`
`when bright light strikes the photoreceptor cell membranes. Aerobic cells (which use
`
`mitochondria for glycolysis and ATP production) have evolved many “free radical
`
`scavengers”. A vitamin A-deficient retina, with inadequate amounts of endogenous free
`
`radical scavengers, such as retinol (the alcohol form of vitamin A), cannot neutralize even
`
`normal amounts of free radicals produced in retinal tissue, much less free radicals produced
`
`by photic insult, ischemia, or high intraocular pressure.
`
`Membrane lipid peroxidation is one of the most prominent forms of cellular damage induced
`
`by conditions of oxidative stress(e.g., free radical barrage). The retina contains several
`
`enzymatic free radical scavengers (e.g., superoxide dismutase, and catalase) for neutralizing
`
`free radicals as well as a host of endogenous antioxidant compounds, including (among
`
`others) vitamin E, ascorbate, taurine, glutathione, various vitamin A compounds, and various
`
`carotenoids.
`
`Astaxanthin suppressesfree radicals, such as peroxyl radicals (R000) and singlet oxygen
`
`(102) radicals, and thereby suppresses free radical-induced damage in tissues into which
`
`astaxanthin is transported and accumulates.
`
`Light impinging on the retina penetrates the “inner” layers of the retina (some of which is
`
`called the inner retinal thickness or “IRT” in the ‘533 patent), the middle layer (including the
`
`outer nuclear layer, or “ONL” in the ‘533 patent) of the retina,and passes through the
`
`photoreceptor cell membrane (made primarily of PUFAs) to excite rhodopsin in the rods
`
`(monochrome vision) and photopsins in the cones (color vision) of photoreceptor cells.
`
`Rhodopsin consists of the protein moiety opsin and a reversibly covalently bound cofactor,

`
`retinal (the aldehyde form of vitamin A).
`
`35.
`
`PUFAs exposed to light energy readily form peroxyl radicals that attack and destroy
`
`photoreceptor cell membranesand other membranes and structures in the retina unless the
`
`peroxyl radicals are neutralized by afree radical scavenger, such as an antioxidant. In the
`
`absence of effective free radical scavenging, a barrage of peroxyl radicals is released from
`
`the photoreceptor layer that can travel through the eye causing damage, injury, and disease in
`
`themiddle and inner layers of the retina, and even travel across the vitreous humor to the

`

`
`anterior parts of the eye. For instance, peroxyl radicals from degenerated retina are a primary
`
`or contributing cause of cataracts (Zigler, 1985) and of uveitis (Goto, 1991).
`
`36.
`
`The role of vitamin A in the chemistry of vision was elucidated by George Wald in the
`
`period from the mid-1930s to the mid-1960s, which led to his Nobel Prize in 1967.
`
`Wald,John Dowling, and IR. Gibbons published in the late 1950s and early 1960s the results
`
`of their extensive research on degeneration of the retina caused by vitamin A deficiency
`
`(Dowling and Wald( 1 95 8), Dowling and Wald(1960), Dowling and Gibbons(1961). Those
`
`publications (Ex. 1024, 1025, and 1026, respectively) contain numerous micrographs
`
`showing the reduction of the ONL and IRT, and graphs of the reduction of rhodopsin levels,
`
`in photoreceptor cells lacking adequate vitamin A. See, e.g., Fig. 1 of Ex. 1024 (Dowling
`
`and Wald, 1958) (reduction of rhodopsin levels), Figs. 2, 13, and 15 of Ex. 1025 (Dowling
`
`and Wald, 1960) (reduction of ONL and IRT), Figs. 2 and 10 of Ex. 1026 (Dowling and
`
`Gibbons, 1961) (reduction of ONL and IRT). Later publications (Reading (1980), Zigler
`
`(1985)) explained that the degeneration of the photoreceptor cell membranes, reduction in
`
`thickness of the retina, and reduced rhodopsin levels were due to attack by free radicals,
`
`especially attack by peroxidized lipids emitted from disintegrating outer segments of
`
`photoreceptor rods.
`
`37.
`

`

`
`Vitamin A has three molecular forms relevant to this discussion: an acid form, “retinoic
`
`acid”, required for normal growth, but not active in the chemistry of vision, an aldehyde
`
`form, “retinal”, that combines with opsin to create rhodopsin, and an alcohol form, “retinol”,
`
`which is an antioxidant. Retinal and retinol are enzymatically interconvertible, but the
`
`enzymatic conversion to retinoic acid is irreversible.
`
`The absence of vitamin A in the retina of a vitamin A deficient rat would necessarily result in
`
`the absence of vitamin A as an antioxidant and as a component of rhodopsin, rendering the
`
`retina vulnerable to free radical attack, e.g., during photic insult and during reperfiJsion
`
`following retinal ischemia or high intraocular pressure (the experiments conducted in the
`
`‘533 patent), and causing collapse of the rods in the photoreceptor cell layer by the inability
`
`to synthesize rhodopsin (which is vital to rod structure).
`
`In Fig. 15 of Ex. 1025 (Dowling and Wald, 1960), a retina (middle micrograph and
`
`electroretinogram (“ERG”)), degenerated by6.5 months of vitamin A deficiency with severe
`

`
`damage to the photoreceptor cell layer, was restored to normal structure and fimction (Fig.
`
`15, right micrograph and ERG) by administration of vitamin A.
`
`40.
`
`Figs. 2a to 2d, and 10a to 10c, of EX. 1026 (Dowling and Gibbons, 1961) also irrefiJtably
`
`establish the protective, and therapeutic, effects of vitamin A (as both an antioxidant and as a
`
`component of rhodopsin). Again, the retinal degeneration, including the ONL and IRT, as
`
`shown in Figs. 2d and 10b, is far more severe than reported in the ‘533 patent. As in EX.
`
`1025 (Dowling and Wald, 1960), in EX. 1026 (Dowling and Gibbons, 1961), vitamin A
`
`protected the eye from retinal degeneration (group receiving vitamin A, Figs 2a and 10a) and
`
`healed the degeneration and resultant disease when administered therapeutically (Figs. 2d
`
`and 10c) after free radical-induced retinal injury in a different group.
`
`41.
`
`If adequate vitamin A is available and photoreceptor cells are undamaged, rhodopsin levels
`
`are normal. The reduction of ONL, IRT, and rhodopsin levels in the ‘533 patent reflect the
`
`free radical scavenging mechanisms being temporarily overwhelmed by a free radical
`
`barrage and consequent damage to the photoreceptor cells. The much more pronounced
`
`reduction of rhodopsin levels in EX. 1025 (p. 588, Dowling and Wald, 1960) and Fig. 10 of
`
`EX. 1026 (Dowling and Gibbons, 1961), compared with the minor, short term, drop in
`
`rhodopsin levels in the ‘533 patent, reflect the combination of vitamin A deficiency and more
`
`severephotoreceptor cell damage in the Dowling et al. references.
`
`42.
`
`Fig. 15 of EX. 1025 (Dowling and Wald, 1960) and Fig. 10 of EX. 1026 (Dowling and
`
`Gibbons, 1961) are notable for showing not only the retinal degeneration (including
`
`reduction of ONL and IRT) in rat retina caused by vitamin A deficiency, but prevention of
`
`such degeneration by vitamin A, and reconstruction of degenerated rat retinal layers by
`
`administration of vitamin Aafter retinal injury (in different test groups). This protection
`
`against retinal degeneration (in the control group that received vitamin A) and “treating” of
`
`retinal degeneration in the vitamin A deficient group that subsequently received vitamin A, is
`
`biochemically, prophylactically (in the case of prevention) and therapeutically (in the case of
`
`damage, injury, and disease) equivalent to the administration of astaxanthin to rats (since
`
`astaxanthin is an antioxidant and is also converted in rat retina to vitamin A(Massonet et al.
`
`(EX. 1008, (1965) and EX. 1010 (1961b)).

`
`43.
`
`Therefore, if astaxanthin is administered before an event that would otherwise cause a free
`
`radical barrage(e.g., vitamin A deficiency, photic insult,reperfusion after ischemia or high
`
`intraocular pressure), astaxanthin is necessarily transported to the retina and scavenges
`
`(neutralizes) free radicals before they can cause damage. If astaxanthin is administered after
`
`free radical-induced injury of the retina, astaxanthin is converted in rat retina into vitamin A,
`
`which is then used to reconstruct the retina (explained in Dowling et al., 1958, 1960, and
`
`1961), assuming that irreversible damage of the cornea (from xerophthalmia) and retinahas
`
`not occurred.
`
`44.
`
`Whether the retinal degeneration arises from vitamin A deficiency or from photic insultor
`
`reperfiJsion following ischemiaor high intraocular pressure, the biochemical, histological, and
`
`pathological mechanism is the same: if the photoreceptor cell membranes (particularly the
`
`rod outer segments) are exposed to light energy without adequate free radical scavenging, the
`
`result is a free radical barrage of peroxidized fatty acidsand singlet oxygen that cause retinal
`
`degeneration and reduction of ONL, IRT, and rhodopsin levels. Even in rats with normal
`
`vitamin A levels, intense photic energy or reperfiJsion (after ischemia or high intraocular
`
`pressure) depletes available free radical scavengers, thereby enabling peroxidation of lipids
`
`in the photoreceptor membranes, which unleashes a free radical barrage and resultant
`
`damage, injury, and (if vitamin A deficiency ensues) disease.
`
`45.
`
`Vitamin A deficiency inherently produces the same types of retinal damage and injury that
`
`the experiments in the ‘533 patent produced. Grangaud (in Ex. 1002) and Massonet (in Ex.
`
`1004) administered to vitamin A-deficient rats astaxanthin to prevent, and to treat, one type
`
`of eye damage, injury, and disease (xerophthalmia) caused by vitamin A deficiency or by
`
`lack of antioxidant,but necessarily (inherently) treated other types of eye damage and
`
`injury caused by vitamin A deficiencyor by lack of antioxidant, including the type of damage
`
`and injury that the experiments in the ‘533 patent produced.
`
`46.
`
`The preceding discussion of biochemical, histological, and pathological mechanisms of free
`
`radical-induced retinal degeneration was confirmed in other animal models before the
`
`Critical Date.

`“In contrast, rats raised on a vitamin A-
`
`free diet supplemented with retinoic acid show changes in the outer segments at about
`
`two months (Fig. 6B) and loss of outer segments, inner segments, and about half the
`
`photoreceptor nuclei at about siX months (Fig. 6C). At ten months (Fig. 6D) the

`photoreceptors have disappeared except for one row of nuclei.

`within 16 days.”
