`

`
`·2· · · · · · ·I mean, there is a certain
`
`·3· ·application space and subject matter that the
`
`Page 102
`
`·4· ·patent contemplates.
`
`·5· · · · · · ·BY MR. ZHOU:
`
`·6· · · ·Q.· · So if I come up with -- if I
`
`·7· ·invented a machine that detects the remaining
`
`·8· ·capacity of a battery, how would you determine
`
`·9· ·whether that qualifies as a capacity detector

`
`13· · · · · · ·THE WITNESS:· So I think two
`
`14· ·different things we are talking about, but I
`
`15· ·mean, if it does this function of detecting
`
`16· ·remaining capacity of a battery, then it does
`
`17· ·that function.
`
`18· · · · · · ·If I am putting on the hat of a
`
`19· ·person of skill in the art, I might not
`
`20· ·seriously consider it as a potential structure

`
`22· ·patent though.
`
`23· · · · · · ·BY MR. ZHOU:
`
`24· · · ·Q.· · I see.· So there is this sort of a
`
`25· ·commercial viability aspect of that, right? I

`·1· · · · · · · MICHAEL C. BROGIOLI, PH.D.
`
`·2· ·mean, if it's -- you have this giant machine,
`
`·3· ·you may not be able to squeeze that into a
`
`·4· ·notebook computer or a mobile phone, right?· Is
`
`·5· ·that what you're referring to?
`
`·6· · · ·A.· · I mean, I think that's one case, you
`
`·7· ·know, if it was a machine the size of this
`
`·8· ·room, it's not going to fit into a Smartphone.
`
`·9· · · ·Q.· · Right.· But in terms of the scope of
`
`10· ·the term itself, if the machine is capable of
`
`11· ·detecting a remaining capacity of the detector,
`
`12· ·you would consider that to be a capacity
`
`13· ·detector, right?
`
`14· · · · · · ·MR. BARROW:· Objection.· Form.
`
`15· · · · · · ·THE WITNESS:· I don't know that --
`
`16· · · · · · ·MR. BARROW:· Objection.· Scope.
`
`17· · · · · · ·THE WITNESS:· I don't know that I
`
`18· ·formed an opinion on that, but, I mean, if the
`
`19· ·machine is -- if it detects a remaining
`
`20· ·capacity of a battery, it detects a remaining
`
`21· ·capacity of a battery.
`
`22· · · · · · ·Again, I list three examples that I

`
`24· ·certainly understand as potential options given

`
`·6· ·in the context of claim construction, right?
`
`·7· · · ·A.· · Correct.
`
`·8· · · ·Q.· · And part of claim construction is to
`
`·9· ·define a claim term and put some balance on the
`
`10· ·claim term to decide what it includes or what
`
`11· ·it excludes, right?
`
`12· · · ·A.· · That's my understanding.
`
`13· · · ·Q.· · So one potential bound you put on
`
`14· ·the claim is described in your specification,
`
`15· ·it has to detect a remaining capacity of a
`

`
`17· · · ·Q.· · So a motion detector by itself,

`

`
`·2· · · · · · ·BY MR. ZHOU:
`
`·3· · · ·Q.· · The technology field relevant to a
`
`·4· ·demodulator as compared to the technology field
`
`·5· ·of the '794 patent.
`
`·6· · · · · · ·MR. BARROW:· Objection.· Form.
`
`·7· ·Objection.· Scope.
`
`·8· · · · · · ·THE WITNESS:· I'm not sure the
`
`·9· ·demodulator's in a field, but I mean, you know,
`
`10· ·it's used in maybe single processing or
`
`11· ·wireless communication or things like that or
`
`12· ·some applications of it.· I don't think I have
`
`13· ·formed an opinion as to -- if that term itself
`
`14· ·is applicable to this claim term.
`
`15· · · · · · ·BY MR. ZHOU:
`
`16· · · ·Q.· · So as you sit here today, you don't
`
`17· ·have an opinion as to whether the term
`
`18· ·"demodulator" is applicable to the construction
`
`19· ·of the capacity detector term at issue in this
`
`20· ·case.

`

`
`·2· · · ·Q.· · Do you know what a rectifier is?
`
`·3· · · ·A.· · So again, a similar term that is
`
`·4· ·used in various ways in engineering.· I don't
`
`·5· ·know -- I will stop there.
`
`·6· · · ·Q.· · You have heard of the term?
`
`·7· · · ·A.· · Yes.
`
`·8· · · ·Q.· · In what context have you heard of
`
`·9· ·the term?
`
`10· · · ·A.· · Electrical engineering or circuit
`
`11· ·design or things like that.
`
`12· · · ·Q.· · Do you believe a rectifier can serve
`
`13· ·as a battery capacity detector in the context
`
`14· ·of the '794 patent?
`
`15· · · · · · ·MR. BARROW:· Objection.· Form.
`
`16· ·Objection.· Scope.
`
`17· · · · · · ·THE WITNESS:· I haven't formed an
`
`18· ·opinion on that.
`
`19· · · · · · ·BY MR. ZHOU:
`
`20· · · ·Q.· · Do you believe the term "rectifier"
`
`21· ·is relevant to -- to the construction of
`
`22· ·capacity detector in the context of the '794

`
`·1· · · · · · · MICHAEL C. BROGIOLI, PH.D.
`
`·2· · · · · · ·THE WITNESS:· I don't have an
`
`·3· ·opinion today if rectifier is relevant to that
`
`·4· ·claim construction term, beyond what's in my
`
`·5· ·declaration.
`
`·6· · · · · · ·Well, I don't talk about rectifier
`
`·7· ·in my declaration.
`
`·8· · · · · · ·BY MR. ZHOU:
`
`·9· · · ·Q.· · In Paragraph 29, among the examples
`
`10· ·you provided, the last one is a voltage
`
`11· ·detector.
`
`12· · · · · · ·Do you see that?
`
`13· · · ·A.· · Yes.
`
`14· · · ·Q.· · Could a voltage detector be used to
`
`15· ·serve the function of detecting a remaining
`
`16· ·capacity of the battery?
`
`17· · · ·A.· · I haven't formed an opinion on that
`
`18· ·as of today.
`
`19· · · ·Q.· · And by identifying voltage detector
`
`20· ·as an example here, you are not intending to
`
`21· ·opine that voltage detectors are a type of
`
`22· ·capacity detector, right?
`
`23· · · ·A.· · The voltage detector is included in
`
`24· ·29 with the intention of showing various
`
`25· ·structures for detecting things.· I haven't

`
`·1· · · · · · · MICHAEL C. BROGIOLI, PH.D.
`
`·2· ·formed an opinion as to whether the universe of
`
`·3· ·voltage detectors, I think you're asking if it
`
`·4· ·could be used in the patent that way.
`
`·5· · · ·Q.· · So the five examples -- four, I'm
`
`·6· ·sorry, strike that.
`
`·7· · · · · · ·The four examples you provide here,
`
`·8· ·motion detectors, photo detectors, infrared
`
`·9· ·detectors and voltage detectors, you are
`
`10· ·identifying these examples only to show that
`
`11· ·the term "detectors" can be used to refer to
`
`12· ·structures in other fields; is that generally
`
`13· ·correct?
`
`14· · · · · · ·MR. BARROW:· Objection.· Form.
`
`15· · · · · · ·THE WITNESS:· I am saying that those
`
`16· ·are examples of detector and they are
`
`17· ·well-understood in electrical engineering
`
`18· ·contexts to -- and again, to continue, to
`
`19· ·connote a variety of structures.
`
`20· · · · · · ·BY MR. ZHOU:
`
`21· · · ·Q.· · But those structures may or may not
`
`22· ·be the same structures as was used for a
`
`23· ·capacity detector in the context of the '794
`
`24· ·patent, right?
