`
`1. A composition suitable for injection through a
`needle into a host, comprising:
`microparticles comprising a polymeric binder; and
`an injection vehicle, wherein said microparticles are
`suspended in said injection vehicle
`at a concentration of greater than about 30 mg/ml
`to form a suspension,
`wherein a fluid phase of said suspension has a
`viscosity greater than about 20 cp and less than
`about 600 cp at 20°C.,
`wherein the viscosity of said fluid phase of said
`suspension provides injectability of the composition
`through a needle ranging in diameter from 18-22.

`
`Petitioners’ Argument:
`CMC at 3% always necessarily has a viscosity within the
`•
`claimed range of the patent, regardless of any other
`ingredients or how they are mixed.
`
`Petitioners’ Attempt:
`Ignores the numerous types and grades of CMC;
`•
`Ignores how the injection vehicle is made;
`•
`Ignores other ingredients in injection vehicles;
`•
`Improperly relies on Mark Tracy Declaration (not prior
`•
`art); and
`Relies on unsupported opinion of expert, Dr. DeLuca.

`Viscosity Grades of CMC
`
`DeLuca 2nd Dep. Tr.
`Exh. 2081 at 122:3-
`7, 123:24-124:5
`
`Q. So a person of skill in the art could use a
`medium viscosity grade CMC as an injection
`vehicle for a microparticle?
`
`A. It could.
`
`Q. Okay. But in your opinion it’s possible for a
`high viscosity grade CMC to be used as an
`injection vehicle for a microparticle, right?
`
`A. It’s possible.
`
`Patent Owners’ Obs. (Paper 50) at 1.
`

`
`
`
`Factors Affecting Viscosity
`
`• CMC Viscosity Grade
`
`• Other ingredients, e.g., polysorbate and NaCl
`
`• How injection vehicle is made and/or sterilized
`
`• Order of addition of ingredients, e.g., NaCl
`
`The ’061 patent accounts for all of these
`potential changes to viscosity by claiming the
`viscosity range, and not a specific formulation.
`
`Patent Owners' Response (Paper 33) at 21, 25, 27-28.
`
`16
`
`
`
`Johnson Disclosure
`• No disclosure of CMC Grade
`
`• 10 times more polysorbate than in an
`embodiment in ’061 patent
`
`• No disclosure of how injection vehicle is made
`and/or sterilized
`
`• No disclosure of order of addition of sodium
`chloride
`
`The ’061 patent accounts for all of these
`potential changes to viscosity by claiming the
`viscosity range, and not a specific formulation.
`17
`Patent Owners' Response (Paper 33) at 21, 25, 27-28.
`
`
`
`Polysorbate Affects Viscosity
`
`Q. So the addition of polysorbate in the aqueous
`solution with CMC can impact CMC directly or
`indirectly, right, through these interactions?
`
`DeLuca 2nd Dep. Tr.
`Exh. 2081 at
`236:20-25
`
`A. It could.
`
`Patent Owners' Obs. (Paper 50) at 5-6.
`
`18
`
`
`
`Sodium Chloride Affects Viscosity
`
`“But as Dr. Berkland pointed out,
`whether the solute is added before
`or after the CMC affects the
`viscosity obtained . . . .”
`
`“. . . add[ing] CMC after sodium
`chloride, thereby lead[s] to lower
`viscosities.”

`Mixing Affects Viscosity
`
`Berkland Decl.
`Exh. 2014 at ¶ 67-
`69, see also ¶ 130
`
`“CMC can form both physical and chemical
`interactions with itself which increase
`viscosity.”
`
`“More polymer chain entanglement occurs
`with increasing CMC concentration, which in
`turn increases the viscosity of the overall
`solution due to large increases in the
`resistance to flow. (See Exh. 2031, DeLuca
`1996 at 291.)”
`
`“Additionally, CMC can exhibit inter- and intra-
`molecular interactions that affect viscosity,
`such as hydrogen bonding or electrostatic
`bonding . . . . The more of these interactions,
`the more viscous the solution becomes.”
`
`Patent Owners' Response (Paper 33) at 24, 26-27.
`
`26
`
`
`
`Mixing Affects Viscosity
`
`Q. . . . Dr. DeLuca, you understand that Dr. Berkland
`also testified in his last declaration that the method of
`dissolution or mixing could impact viscosity. Do you recall
`that?
`
`A. Yes.
`
`DeLuca 2nd Dep. Tr.
`Exh. 2081 at
`238:21-239:12
`
`Q. For instance, using different mixing methods and
`speeds could result in solutions having different
`viscosities. Do you recall that?
`
`A. Yes.
`
`Q. Now you didn't dispute that in your reply declaration,
`correct?
`
`A. That's correct.

`Mixing Affects Viscosity
`
`DeLuca 1st Dep. Tr.
`Exh. 2016 at
`182:10-19; 184:4-6
`
`Q. My question is: What is polymer chain entanglement?
`
`A. Just that there's, you know, an entanglement of the
`polymer chains. They're not linked. They're not linear.
`They're pretty much kind of mixed together and tangled,
`and, I guess, it's like if you get your hair all tangled up in
`a whirlpool. It may resemble that.
`
`Q. Okay.
`
`A. But it's -- the chains are kind of mixed in with each
`other.
`
`Q. So other additives may impact the entanglement as
`well?
`
`A. Yes.

`Dr. DeLuca’s Unsupported Circular Testimony
`
`“A particle in water’s going to
`settle pretty fast. In honey, it’s
`going to take a long time. But it
`would be difficult to inject the
`honey over water.”
`
`Petitioners’ Reply:
`“So something like water, with a
`negligible viscosity of 1cp, will
`allow particles to settle quickly,
`whereas particles suspending in
`honey, with a viscosity of about
`10,000cp, would take much
`longer to settle.”
`
`Dr. DeLuca’s Second
`Declaration:
`“So something like water, which
`has a relatively negligible
`viscosity of 1cp, will allow settling
`of the agent quickly. An agent
`placed in honey, with an
`approximate viscosity of about
`10,000cp … would take much
`longer to settle.”

`
`Q. So your understanding of inherency is that CMC
`will fall within the range identified in the
`specification for viscosity plus or minus 10
`percent?
`
`A. . . . It's inherent that it's going to be -- it's
`going to be within a similar value, maybe not be
`the same but it certainly would be in a range that's
`-- that's, you know, could be within, you know, 10
`percent of the value.

`
`Q. . . . So what -- what is the inherent property of
`CMC that you are referring to when you were
`mentioning inherency in your reply report with
`respect to that compound?
`
`A. That if the low grade -- if a certain grade was
`being used, that a microparticle, which might be
`different, a different product, but similar in size
`and concentration, one would expect the viscosity
`to be in the range of that that's what we are
`referring to.
`
`Q. Right. And then you said within a margin of
`error, which is plus or minus 10 percent?
`
`A. Yeah. Yes.
