`THE USHER: Hearing IPR 2019- 01657 and we are ready
`
`to go.
`
`JUDGE O'HANLON: Good morning, everyone. You can
`be seated if you're standing. This is a hearing in case IPR 2019-
`01657, Mylan Pharmaceuticals Inc. v. Sanofi-Aventis
`Deutschland GmbH concerning U.S. P atent No. RE47,614. I'd
`like to begin by having counsel for the parties introduce
`themselves, starting with Petitioner please.
`
`MR. TORCZON: Good morning, Your Honors. I'm
`Richard Torczon, lead counsel for Petitioner Mylan
`Pharmaceuticals. With me and presenting argument today is
`Doug Carsten in San Diego and on the audio line we also have
`Tasha Thomas from our team and I believe representatives from
`Mylan are on the line and possibly the other real parties of
`interest.
`JUDGE O'HANLON: Thank you, Mr. Torczon. So Mr.
`Carsten will be presenting all the argument today or will you be
`splitting it?
`MR. TORCZON: Mr. Carsten will present all of the
`argument, your Honor.
`MR. CARSTEN: Good morning.
`JUDGE O'HANLON: Good morning, Mr. Carsten. Thank
`you, and who is representing Patent Owner, please?

`MR. RENNER: Yes. Good morning, Your Honors. This is
`Karl Renner from Fish & Richardson. I'm joined by my
`colleague John Goetz. Also on the line we have several people,
`representatives from Sanofi as well as from Petitioner's, sorry
`Patent Owner's counsel. We'll be splitting our time today. John
`will present on some of the issues. I will present on others. So
`we'll both be speaking.
`JUDGE O'HANLON: So Mr. Renner and Mr. Goetz, is that
`how you pronounce it?
`MR. GOETZ: Yes, sir.
`JUDGE O'HANLON: Goetz, thank you very much. So
`thank you all. I am Judge O'Hanlon. I am joined by Judges
`Melvin and Marschall. A few housekeeping items before we get
`started. First of all, thank you for your flexibility in conducting
`this all video hearing this morning. If at any time during the
`proceeding you encounter technical or other difficulties that you
`feel undermine your ability to adequately represent your client
`please let us know, for example, by contacting the team members
`who provided you with the contact information for today's
`hearing.
`To minimize the potential for distractions, please mute
`yourselves when you're not speaking, and when referencing
`demonstratives, papers, or exhibits, please clearly state the paper
`number or slide number so we can follow along more easily and
`for clarity of the record.

`
`Per our order dated December 17th, each side will have 45
`minutes of total time to argue. Petitioner will go first followed
`by Patent Owner and each side may reserve time for rebuttal. I
`will be keeping time but with this video hearing there's no
`common clock for us all to look at so please keep track of the
`time yourselves. If you run over during your argument in chief
`I'll let you continue using time that you reserved for rebuttal, but
`again – I'll try and let you know when this happens but please
`also keep track of your time yourselves.
`As usual, speaking objections are not allowed. If you have
`anything to note you can do so during your time to argue and
`finally, please be aware that members of the public may be
`listening to the hearing today. And with that, I'll invite Mr.
`Carsten to begin. Mr. Carsten, would you like to reserve any
`time for rebuttal?
`MR. CARSTEN: Yes, I would. I'd prefer to use 25 minutes
`now and reserve 20 minutes if possible.
`JUDGE O'HANLON: Okay.
`MR. RENNER: Your Honors, may I -- I’m not seeing the
`video for Your Honors. Are others seeing -- seeing everyone
`involved? I can see all counsel and Alan , I can see a box for
`you and an accordion box for no video for the judges.
`
`(Pause, for technical assistance.)
`JUDGE O'HANLON: Okay. If there are no other technical
`issues, Mr. Carsten, you may begin when you're ready.

`
`
`MR. CARSTEN: Thank you. Good morning. Douglas
`Carsten representing Petitioner Mylan and may it please the
`Court. This IPR posits the question is it obvious to use a spring
`washer with leg or fixing elements to link one component or hold
`one component against another and the answer is resoundingly
`yes. We'll spend about 25 minutes up front just sort of walking
`through the level of skill in the art and the application of that
`skill, what that person knew, and so the three references that we
`rely upon.
`I'd like to call your attention to three things that I think
`you'll be hearing from my counterparts repeatedly through their
`proceeding and presentation and I'm going to call them the
`triumvirate of errors. First, you're going to hear Sanofi minimize
`the application of the level of skill in the art, again this is in
`violation of KSR . They're going to have this person not apply
`the normal level of skill in this predictable field. Second, you're
`going to hear them misread patents, the patent at issue here, the
`Harms patent, as well as the prior art. And third, you're going to
`hear a piecemeal response to the art that we cite in connection
`with our obviousness arguments and that was specifically called
`out, for example, in the Board's Institution decision at page 21,
`and Sanofi never rectified that error throughout the proceeding.
`If I may turn to slide 2, there are 18 claims at issue here.
`Four of them are independent. Let's turn to slide 3. This is
`representative claim 1 that claims a complete device, the device

`
`that's operational and that device includes a spring washer with
`at least two fixing elements configured to axially and
`rotationally fix the spring washer relative to that housing.
`On slide 4 I've got the other three independent claims here
`and I pointed out some of the slight differences between them,
`but in large part Sanofi has argued this case in bulk. They've
`argued with one or two minor exceptions the claims all together.
`What is the Petitioner's case for obviousness here? I'm at
`slide 5. Petitioner set forth, Mylan set forth in detail how each
`and every element of the asserted claims here is found in the
`Burren reference with additional spring washers and additional
`fixing elements specifically taught in Venezia and De Gennes.
`Slide 6. The Board understood our argument and that's --
`the panel understood. I call the panel's attention to some of the
`slides that my counterparts will present. They won't address
`Burren as a whole. They won't address Venezia as a whole.
`They won't address de Gennes as a whole. They won't address
`all three together. Instead, what they will do is they will parse
`and cut up Burren and say the second specific embodiment of
`Burren doesn’t apply and they'll focus on the first specific
`embodiment of Burren and they won't address the overarching
`disclosure, the broader disclose that we'll see in Burren. That's
`one of the triumvirate of errors.
`Let's turn to Harms. That's the patent that's being
`challenged here. I'm at slide 8, and Harms has a very broad

`
`disclosure about spring washers. It says, I've got a portion of the
`specification here at column 5, lines 10 through 20:
`"The loaded spring washer may hold the cartridge and the
`cartridge retaining member in permanent abutment on the distal
`end side."
`What does it say about the same elements of fixing? I'm on
`slide 9. The fixing element disclosure in Harms is similarly
`flawed and it allows expressly motion. I've got a passage here
`on slide 9 from the Harms patent. It is column 5, lines 29
`through 43 and if I may read the penultimate sentence on that
`excerpt:
`"Of course, axial movement of the spring washer 50 for
`loading the spring washer or during relaxing of the spring washer
`is allowed."
`It goes on in the last sentence excerpted here:
`"Fixing elements 52, preferably do not rotate and/or do not
`move axially during operation of the drug delivery device."
`Again, preferably. Some motion is allowed. Now as an
`aside I'd like to dispatch of an argument most easily shown in
`Sanofi's surreply. Sanofi, I'm here at slide 10, in their surreply
`had a footnote. They made the argument before but this is the
`most clean excerpt of it. It says Sanofi disagrees with Mylan's
`assertion in the petition that the Harms patent provides an
`alternative fixing element structure. This portion of the
`specification citing column 5, lines 61 through 67, describes

`
`characteristic features of a "positioning element." Well we can
`look at column 5. I've got it excerpted immediately underneath.
`Each and every instance in the specification there talks about
`positioning and fixing elements interchangeably. You can look
`through it yourself.
`JUDGE O'HANLON: Mr. Carsten, that seems to be I guess
`directed to the Patent Owner's proposed construction of fixing
`elements. But if you look at the claims, looking at claim 1 for
`example, it requires that the fixing elements be configured to
`axially and rotationally fix the spring washer relative to the
`housing. So don't the claims specify that the spring does not
`move relative to the housing regardless of whether there may be
`instances in the specification that say in some embodiments it
`may move relative to the housing?
`MR. CARSTEN: I don't believe so. So there isn't -- what
`Sanofi is trying to do is to read the word completely into the
`claims, to completely fix, to not move at all and that's simply not
`found anywhere in the art. So in each instance, a person of skill
`in the art as Dr. Erdman identified understands the way that
`these spring washers operate. They operate by flexing. They
`operate by giving a bit in order to press one component up
`against another. So there will always be some degree of motion
`or some degree of latitude required during the setting of the
`device and that's the way the spring washers move, spring
`washers operate. They have to have that ability to give, ability

`
`to move slightly in order to make that (indiscernible.)
`JUDGE O'HANLON: So you're referring to simply the
`flexion of the spring but not movement of the fixing elements;
`correct?
`MR. CARSTEN: Well, but if you move the spring
`obviously the fixing elements will need to accommodate that
`motion as well and that's I think what's being taught in the
`Harms reference and throughout the art that we've cited. Let's
`talk about Venezia, if I may. Venezia for example has the
`tongue and the slot iteration. The slot is defined to accept the
`tongue to hold it fixed. Is there some play in that? Probably. In
`part because the tongue is on the hump piece of the spring
`washer. You could minimize that moving and maybe eradicate it
`all together by moving the tongue elements on to the flat sides of
`the spring washer.
`Let's also look at the second specific embodiment of Burren
`which has the snap -fit. That snap-fit once you click it in it
`should hold it relatively fast but given tolerances, there will or
`inevitably be the ability for there to be some motion. The claims
`cannot require perfection because that -- the entire premise of
`the point here, the invention which is known from Schofield and
`others which we'll get to, is to account for tolerances,
`differences between, for example cartridges, in holding them
`steady in the device and so as a result, you know, to say that a
`spring washer which itself has tolerances that fits into another

`
`piece of a device which itself has tolerances to require no
`movement at all simply undermines the reality of the world. It
`just doesn't make any sense and that's what Dr. Erdman said and
`that's a second version or iteration of the triumvirate of errors
`that we see here is that Sanofi sort of glides over the way that a
`person of skill in the art would understand this predictable art to
`operate by requiring, for example, this fundamental perfection in
`fixation. You know, you can say that a boat anchors and that
`boat is fixed, but it still allows the boat to move with the tides.
`That's still fixed. It's attached and it's attached securely, but it
`still accounts for what we're talking about here. There are
`tolerances. There are real world consequences and springs have
`to flex. That's the way that springs operate. So I would disagree
`with Sanofi's construction but I think the construction issue may
`well also be a red herring in a sense.
`Let me talk about the petition here. So we relied upon
`these three references. Burren as the overarching reference and
`then supplemented by two more specific references that added
`color to the spring washer and fixing element and those two
`references are identified and were included in part because we
`read the term fixing elements as we were preparing the petition
`and said aha, Sanofi might come back and say this is means plus
`function and if it's means plus function that would be the
`narrowest possible construction you would have. You'd have
`simply the disclosed structures for that function as well as

`
`statutory equivalence. Any construction that Sanofi can provide
`would necessarily be broader than that construction, the means
`plus function and I submit with respect that we satisfied our
`burden, that we've rendered obvious the claim based upon the
`arguments in the petition under even that most narrow and most
`stringent claim construction. So I don't believe that there's a
`claim construction issue that needs to be addressed given that
`Sanofi in its first paper raised a red flag on means plus function
`112(6) this issue.
`So I submit that simply reading the claim under its plain
`and ordinary meaning or even under Sanofi's construction which
`means to securely attach and these are securely attached, as in
`view of the Harms disclosure. I don't think that we have a claim
`construction issue and I believe Mylan has met its burden. I see
`perhaps a member of the panel has a question.
`JUDGE MELVIN: Yes, I do. This is Judge Melvin. So I
`just want to make sure I understand your point about relative
`motion. I mean you argue on one hand that because the spring
`must flex it is a moving element and so there must be some
`motion of the spring permitted, right? But then you use the
`analogy of an anchor and that matches fairly closely to the
`analogy I was thinking of, which is holding oneself still while
`standing on a subway train, right? So in both of those examples,
`the anchor point itself may be perfectly fixed while allowing
`relative motion at the other end, right? So the boat moves with

`
`the tide. You might jostle a bit on the subway train but
`nonetheless, that doesn't necessarily mean that the anchor point
`itself moves, right? So, you know, here it's the fixing element. I
`think that maybe what I want to understand is that there are two
`arguments you're making and I want to make sure I understand
`them correctly.
`So one is the spring itself has to flex and so that requires
`some relative motion but I think you would agree that that's not
`necessarily relative motion at the fixing element and then you
`have another argument that is well, because of the practical
`realities of the world, the fixing element itself also needs some
`tolerance and therefore will allow some relative motion of the
`fixing element itself. Is that accurate?
`MR. CARSTEN: That's absolutely correct. So there are,
`well as we all know every action has an equal and opposite
`reaction and so there are consequences to the spring requiring a
`flexure.
`JUDGE MELVIN: Right.
`MR. CARSTEN: And so, well for example when you're on
`the subway train and the voice comes over the speaker hold on,
`we're pulling into the station, it's time to stop. You know, your
`feet may well shuffle. Your fixed point, your anchor may well
`shuffle simply because of there's a consequence of the effects
`going on your upper body where your center of gravity is for
`example; correct? So I think that you need to -- a person of

`
`skill, a skilled artisan understands that there has to be some
`accounting at the fixing point that allow for that kind of, for the
`stresses that the spring washer itself will encounter.
`Secondly and separately I think that there is the
`requirement, just a real world requirement that there's going to
`be tolerances between where the item fixes and the fixing
`element or structure, whatever it might be, snap-fit, slot- fit,
`whatever, and you can by design -- you know, it's tongue slot as
`in Venezia for example -- you can minimize the parameters of
`construction of manufacture such that that tongue is held very,
`very tightly and may not move perceptibly at all. But if you're
`going to say that fixed securely means absolutely still during the
`entire operation of the device, then that can't happen and that's I
`think one of the points that Dr. Erdman makes.
`So yes, there are two arguments there and I think frankly
`based upon the disclosure we just saw of Harms I think that
`Sanofi's construction is wrong. But again, I think it may be a red
`herring because to my mind we've already established
`obviousness under the most stringent possible claim construction
`which is 112(6) and so whatever claim construction Sanofi
`wishes to build upon or put upon that's consistent with Harms,
`we would meet that as well.
`JUDGE MELVIN: Are you sure that it's necessarily true
`that any construction other than a means plus function
`construction will be broader than the means plus function

`
`construction?
`MR. CARSTEN: Well, the only wrinkle I have -- so the
`construction is obviously the structures that are disclosed in
`Harms that propose the function if it were means plus function,
`right?
`JUDGE MELVIN: Right.
`MR. CARSTEN: Hold on to the statutory equivalence, so I
`suppose theoretically you might be able to come up with a
`construction that accomplishes or that builds and meets all of the
`disclosed structures would somehow thread a needle through and
`doesn't capture all of the statutory range of constructions. But
`I've wracked my brain on this, Your Honor, and I can't think of a
`possible construction that would do that here that would be
`consistent with the structures in Harms.
`JUDGE MELVIN: Well, maybe your view is that Patent
`Owner is taking too narrow a view of the required function and
`actually has nothing to do with the structure itself, right? That
`the function Patent Owner is reading from the claim is one of
`absolute securement or fixation --
`MR. CARSTON: Exactly, Your Honor.
`JUDGE MELVIN: -- and that's where you take issue.
`Okay.
`MR. CARSTEN: And the fixing element, you know, it's
`required to be configured to hold that spring washer, right? I
`mean the word fixed appears there of course but it doesn't

`know, motionless. I don't see the word motionless. I don't see
`complete. I don't see any of those concepts in the claim
`language and when I read the Harms disclosure as a person of
`skill, a skilled artisan would, I see a lot of talk about preferably
`and I see a lot of talk about allowing tolerance for movement.
`So I think that the construction is just incorrect but again, I don't
`believe that that's dispositive. I don't think that -- I think under
`any construction that's consistent with Harms patent .
`JUDGE MELVIN: Thank you.
`MR. CARSTEN: If I may I'd like to -- I've got maybe, I
`did a lot of the things I wanted to talk about up front. I've got
`about seven minutes according to my clock. I think it's
`important to know sort of or point out just a couple of ideas here.
`I'm at slide 13 and 13 is a discussion about what a person of skill
`in the art knew. Here is an excerpt from a textbook, a 2000
`textbook by Norton and identifies spring washers. These spring
`washers are ubiquitous and tellingly at page 802 it talks about
`spring washers and what a person of skill in the art, a skilled
`artisan, would know about them. It says,
`"All provide a push force and are commonly used to load
`something axially, such as the take up end play on a bearing."
`So, you know, these things are well known taught to first
`year mechanical engineers and on the next slide 14, we've got a
`patent from the 1950s, the Schofield patent which talks
`

`
`specifically about accommodating various lengths of cartridges
`in an injection device and they do that by using a spring washer.
`So this concept has been around forever and the tool box in
`this predictable art that a skilled artisan sees before him or her is
`replete with spring washers. This is nothing new and moreover I
`think an interesting point that Dr. Erdman raised is the Harms
`patent itself requires that the skilled artisan apply that level of
`skill, that knowledge by virtue, and here I've got on slide 16 a
`passage or paragraph from Dr. Erdman's declaration. You know,
`those broad disclosures in Harms require the use of the person of
`skill in the art to put on their thinking caps to implement what it
`is that's being taught. There's very little detail provided.
`Now, I'd like to just turn to a couple of other issues. I've
`got about five minutes left on the clock here but obviously I
`want to make sure that I'm addressing whatever issues or
`questions or concerns that the panel has, so feel free. I talked
`earlier about the triumvirate of errors that --
`JUDGE MARSCHALL: Excuse me. I'm going to step in
`here, Judge Marschall.
`MR. CARSTEN: Yes.
`JUDGE MARSCHALL: I know you probably are ready for
`it in rebuttal given the layout of your slides, but I'd like you to
`address the argument that de Gennes is not analogous art and in
`particular like to know how you define the problem to be
`addressed.
`
`
`
`

`
`
`IPR2019-01657
`Patent RE47,614E
`
`
`MR. CARSTEN: Okay. Certainly. So I think that de
`Gennes, well de Gennes is analogous art. I mean we know that
`by virtue of the Donner case, the Donner case that both sides
`have cited, the recent Federal Circuit case from November of last
`year. So obviously it's a two question analysis. We're not
`saying that automotive art, for example, are identical to medical
`device art.
`So the first prong we can see no, that's not accurate. But
`on the second prong the question is reasonable pertinence, right?
`Is the solution provided here in de Gennes reasonably pertinent
`to a person of skill in the art, a skilled artisan, in solving the
`problem. The problem here as I see it that I think as Dr. Erdman
`tellingly identifies in his declaration is the holding of -- the
`accounting for tolerances among cartridges in this medical
`device. The abutment of one component against another using a
`spring washer with these to fixing. So that's what we're looking
`at and when we look at that problem we see that Schofield solved
`that problem of abutting a cartridge against another by using
`spring washers. We see that Burren taught spring washers using
`legs or using fixing elements, the snap-fit in the second iteration,
`second specific embodiment for example plus the disclosure.
`But remember we just looked at --
`JUDGE O'HANLON: I'm sorry. Is it your position that
`Burren discloses a spring washer?
`MR. CARSTEN: Burren, well Burren certainly I believe

`
`teaches a spring washer in the specification, the broad disclosure
`of Burren. To my mind there's no question. The specific
`embodiments --
`JUDGE O'HANLON: And it discloses a spring washer with
`fixing elements? Is that what I just understood you to say ?
`MR. CARSTEN: I believe it does disclose that or that it
`teaches that to a person of skill in the art in the specification. I
`do believe, yes and I think that was our position. I understand
`that the Patent Owner had some difficulty with some of the --
`that perhaps previously issued decision but I believe that that is
`correct. If I may just complete my response to the analogous art,
`then I can switch over to the Burren disclosure because I think
`that's an important point.
`We just looked at the Norton reference which identified
`spring washers ubiquitously and said hey, spring washers are
`used to load axially and even to take up end play in bearings. I
`mean look at de Gennes. It is using a spring washer, although
`it's called a cover, it is a spring washer with these fixing
`elements to bias one component against another in very much the
`same way that Harms talks about that and specifically in the tool
`kit the person of skill in the art, the skilled artisan, understands
`that spring washers are used to take up end play with bearings.
`de Gennes is a bearing reference. I mean, and this is
`fundamental. So I believe that the use of the cover of the spring
`washer with the fixing element in de Gennes is absolutely

`
`analogous art and meets every reasonable pertinent case out there
`including the recent Donner .
`JUDGE MARSCHALL: When you're looking to define the
`scope of the problem, are you looking to Burren for that
`definition of the problem or are you looking to Harms itself, or
`both?
`MR. CARSTEN: Thank you for the question. It doesn't
`really matter. I know that Sanofi has made a big deal about that
`but I point the panel to the Chamberlain case, 944 F.3d 919
`which talks about, sorry, do we have that? I apologize. Not the
`Chamberlain case. The Talkowski case which I think we cited in
`our opening paper and so --
`JUDGE O'HANLON: The Board opinion case, correct?
`MR. CARSTEN: Yes, exactly. And so, you know, I think
`that the error or the problem to be solved, excuse me, is really
`identical presented between Burren and Harms. They're both
`interesting in solving the same issue and that is on the Burren
`side accommodating various cartridge lengths and on the Harms
`side identifying the cartridges. So whether you look at this as
`focusing in on the problem described in the prior art or the
`problem that's encountering -- that the patent is attempting to
`solve -- it's the same problem. In addition to that, the cases that
`I cited absolutely allow for an examination of the prior art to
`identify the problem and it's consistent and 100 percent on all
`fours with the problems being identified in Harms. So I don't

`
`think --
`JUDGE O'HANLON: Did d e Gennes focus on that same
`problem? I think you defined it as accommodating a cartridge
`length, varying cartridge lengths. It doesn't seem that de Gennes
`is addressing that problem at all.
`MR. CARSTEN: Well, I think it is addressing the holding,
`the taking up end play in a bearing by applying axial force to
`hold one component and abut it against another and that's exactly
`the problem that -- and that's exactly the thing that spring
`washers are known to be used for by, even from fundamental
`knowledge based upon the Norton textbook that we saw. So it's
`all absolutely consistent and the problem is the same problem. It
`just happens to be a different thing.
`Now what Sanofi wants to do here is to define a problem in
`a way that excludes much of the spring washer art. But if you
`allow Sanofi to play with the definition and description of the
`problem, you can always come up with a problem that essentially
`makes almost every piece of art out there not analogous, and so I
`think that what we've got here is Sanofi trying to make the
`problem or position the problem in a way that excludes so much
`art. But even if the panel were to decide that d e Gennes were not
`analogous art here, I still think that we've met our obligations to
`prove obviousness here.
`I see I'm already two minutes or so over the time I've
`allotted. I would like to address about the Burren disclosure if I

`
`may very, very briefly and I think, you know, you're looking at
`the Burren disclosure of springs -- I've got slide 19 -- it talks in
`great detail about compensating springs, et cetera, and then in
`addition to that at slide 23 this is from paragraph 16. This is the
`broad disclosure of Burren divorced from one of the two specific
`embodiments:
`"A spring in accordance with the present invention may be
`a tension spring, flexion spring or torsion spring and, in some
`preferred embodiments, a compression spring. Its shape may be
`that of a coil spring, leaf spring, plate spring, a spring with legs,
`for example, or any suitable configuration."
`That is about as broad of a disclosure as you can imagine
`with respect to springs so I submit that a person of skill in the
`art, as confirmed by Dr. Erdman, that a person of skill in the art
`would understand that Burren teaches spring washers and of
`course it also teaches the use of fixing elements. So yes, I
`believe that a person of skill in the art would unders
