`Proposed Claim Constructions for

`
`
`Claim Term
`
`Defendant’s Proposed
`Plaintiff’s Proposed Claim
`Claim Construction
`Construction
`
`
`“An amplifier comprising”
`
`This phrase constitutes the claim
`preamble of each claim and does
`under well-established Federal
`
`Circuit precedent operate to limit
`the scope of any claim. Thus,
`this claim phrase should not be
`construed as a matter of law.
`
`However, if the Court determines
`otherwise as a matter of law that
`
`the preamble of each claim is a
`limitation, then Crest proposes
`the following ordinary meaning:
`“an audio system including
`electronic devices that amplify
`low-power audio signals to a
`level suitable for driving
`loudspeakers”
`
`Thus the term “an amplifier
`comprising” limits the scope of
`the claims in which it appears.
`
`The term “an amplifier
`comprising” should be
`construed as: “a device for
`
`amplifying audio signals that
`has located within a single

`comprising” not only states a
`necessary and defining aspect

`claimed in the ’542 Patent, but
