`
`signal. In the digital frequency domain, the total acoustic information entering Microphone 1 is
`
`denoted as M1(z) and the total acoustic information entering Microphone 2 is denoted as M2(z).
`
`’357 patent at Eq. 1. The adaptive transfer functions H1(z) and H2(z) are then calculated each as
`
`ratios between the first and the second microphone signals, where the subscripts indicate that either
`
`noise (N) or speech (S) is being received:
`
`
`Id. at Eq. 2; 6:55-56; 6:65-7:2; 7:15-20.
`
`
`
`After the transfer functions are each calculated by a ratio of the first and second microphone
`
`signals, the specification explains, they are used to remove the noise from the signal. Id. at 7:29-
`
`30. Equation 4 sets forth the isolation of the speech signal, wherein the transfer function is applied
`
`to the second microphone signal, and that product is subtracted from the first microphone signal:
`
`
`
`Id. at Eq. 4. Accordingly, while the linear transfer function is calculated using both the first and
`
`the second microphone signals, it is ultimately only applied to one microphone signal.
`
`Here, where the claim term is facially ambiguous about what it means to “apply” a varying
`
`linear transfer function “between” two signals, Google’s proposed construction reflects the claim
`
`language as it is read in view of the specification. See Hologic, 639 F.3d at 1335 (where claim did
`
`not specify a reference for asymmetry of radiation source’s placement, court examined
`
`specification’s description of invention to limit claim term).

`
`IV.
`
`CONCLUSION
`
`For the foregoing reasons, the Court should adopt Defendant’s proposed construction and
`
`reject Plaintiff’s proposals.8
`
`
`8 Currently, Jawbone maintains its assertion of over 200 claims. Google’s Opening Claim
`Construction Brief addresses the claims and corresponding terms most likely to reduce the number
`of issues for the Court and the jury. Google reserves the right to brief additional claim terms
`depending on Jawbone’s ultimate election of claims.
