`

`
`Q· · · ·Now, in your declaration in a few places,
`
`you refer to a standard library preparation, cfDNA.
`
`And I can point you to a few of the spots.
`
`· · · · But could you describe for me, what is the
`
`standard library preparation of cfDNA in 2013?
`
`A· · · ·Could you point me to one of the spots,
`
`please?
`
`Q· · · ·Sure.· If you look at -- it's Footnote 51 on
`
`Page 51.
`
`A· · · ·Okay.· I'm there.
`
`Q· · · ·So what is standard library preparation of
`
`cfDNA?
`
`A· · · ·So a standard library preparation would
`
`involve manipulations of the DNA in order to prepare
`
`it for DNA sequencing.
`
`Q· · · ·And in that context, what did you mean by

`
`there were standard library prep -- protocols
`
`available, for example, from Illumina at the time
`
`and others -- and other vendors as well.
`
`Q· · · ·Is there a particular -- and just as an
`
`example, what would be the standard molar excess
`
`used for adaptors in standard library preparation of
`
`cfDNA?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· Well, I think there's a
`
`range of possible molar -- the molar concentration
`
`of adaptors, and I discuss some of those well-known
`
`ranges here in the declaration.
`
`BY MR. CONSTANT:
`
`Q· · · ·And what would those ranges be?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· Well, we can go to --
`
`I'll find the part here in which we discussed it.
`
`I'm sorry, I'm trying to -- so there are protocols
`
`which we've -- which we can look at here which have
`
`40-fold molar excess, 100-fold molar excess and so
`
`on, so there's a range.· But there's clearly a range
`
`of molar excess given.· There's -- we've -- there's
`
`also a textbook that we point to here, which we talk

`
`BY MR. CONSTANT:
`
`Q· · · ·And which paragraph are you looking at?
`
`A· · · ·I'm sorry, I've scrolled off it already.
`
`· · · · All right.· So I was looking at
`
`Paragraph 141 discussing the molar excess that --
`
`that we -- that we conceive from Schmitt.· Schmitt
`
`teaches using more than a 30-fold molar excess, in
`
`fact, more than a 40-fold molar excess, which is
`
`discussed here in Paragraph 141.
`
`Q· · · ·And what is -- and you referred to a range.
`
`· · · · But what is the range of molar excess that's
`
`used in the standard library preparation methods, as
`
`referred to in your declaration?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· Well, I think that
`
`there's a range, and that range can be -- would be
`
`particular for the -- for the particular work of
`
`that experiment, so I don't think I can -- I can
`
`cite for you a single number.· You're asking for a
`
`range.
`
`· · · · · · ·I think we know that Schmitt uses at
`
`least 30-fold, and then there are -- there's a range
`
`that could be modified depending on the needs of

`
`that experiment.
`
`BY MR. CONSTANT:
`
`Q· · · ·And in -- how would the needs of the
`
`experiment affect what the molar excess would be in
`
`the context of standard library preparation?
`
`A· · · ·So I don't -- I can't give you a full range
`
`of what those needs might be.· But it's clear that
`
`there are needs and -- in certain settings to adapt
`
`with a -- with efficiency to be able to capture
`
`molecules for sequencing.
`
`· · · · And I think the use of at least a standard
`
`molar excess of something like 30-fold would be
`
`completely routine and expected, and that's what we
`
`cite here.
`
`Q· · · ·And just to be clear, it's -- I just want to
`
`make sure I understand what you -- you said before
`
`was that there is a range, and it's modified based
`
`on the needs of the experiment.
`
`· · · · So can you identify any needs of the
`
`experiment that would result in a modification of
`
`the range in the context of standard library
`
`preparation?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· So I think a need of an
`
`experiment is to essentially make available as many

`
`Q· · · ·How would you distinguish between standard

`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· I don't think I have a
`
`single definition to give you.· I can't recall if I
`
`discussed a nonstandard library preparation in my
`
`declaration.· If I did, you could point me to it.
`
`BY MR. CONSTANT:
`
`Q· · · ·In your mind, what is -- what does it mean
`
`to be a standard library preparation versus a
`
`nonstandard?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· Well, there's basic
`
`components to library preparation, some of which you
`
`and I just talked about.· So I would say using those
`
`is standard.· And there are ways to optimize or
`
`change features of the reaction, some might consider
`
`nonstandard, others might not.
`
`· · · · · · ·But library preparation was, you know,

`well known at the time of -- of the time in question

`
`BY MR. CONSTANT:
`
`Q· · · ·Did you talk to anybody about running any
`
`experiments for the purpose of your declaration?
`
`A· · · ·No.
`
`Q· · · ·Did you ask anybody if you could perform any
`
`experiments for your declaration?
`
`A· · · ·No.
`
`Q· · · ·And why not?
`
`A· · · ·I didn't need to, and I wasn't asked to.
`
`Q· · · ·And what do you mean by you -- you didn't
`
`need to run any experiments?
`
`A· · · ·Well, the analysis I performed was directed
`
`to whether a person of skill in the art would have
`
`known how to increase ligation efficiency in 2014.
`
`So I don't believe experimentation by me is
`
`necessary to perform that analysis.
`
`Q· · · ·Is there any way to know what the ligation
`
`efficiency in a specific set of conditions would be
`
`without running the experiment?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· Well, one can look at a
`
`product's notes insert that might come with a kit
`

`

`Q· · · ·And it would be easy for somebody --

`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· I guess I don't know what
`
`you mean by easy, but I think that the experiments
`
`should be reproducible given the exact components.
`
`BY MR. CONSTANT:
`
`Q· · · ·Do you know of any significant barriers for
`
`you as a practitioner to conduct those experiments?
`
`· · · · · · ·MR. MARANDETT:· Objection.
`
`· · · · · · ·THE WITNESS:· I would have to know the
`
`components of the experiment.· But if I did, I
`
`cannot think of a barrier that would prevent me from
`
`doing the experiment.

`
`no.

`Q· · · ·Do you know -- and sitting here today, you

`20 percent.

`20 percent is a standard ligation efficiency to
`
`achieve, as well as other referenc
