10,234,847) Claim(s): Claims 1, 3, 5, 9, 14 OWS's Proposed Construction: "an optical device that combines multiple optical signals of different wavelengths onto a single waveguide" Lumicore's Proposed Construction: "an arrayed waveguide grating that combines optical signals using a slab coupler and phase-shifted waveguide array" Nature of Dispute: The Parties' dispute regarding this term centers on whether "waveguide multiplexer" should be construed broadly to encompass any optical device that performs wavelength multiplexing on a waveguide, or whether the term must be narrowly limited to one specific type of multiplexer architecture — namely, an arrayed waveguide grating ("AWG")

" Lumicore contends that the specification describes liquid coolant circulation in a closed loop as the operative mechanism of the heat sink and that the claims must be construed to require this architecture

Key Intrinsic Evidence Cited by OWS: • Claim 12 of the '015 Patent, which recites "a two-dimensional sub-wavelength grating" without specifying that both dimensions must be sub-wavelength and without reciting any fabrication method
