`Patent No. 7,381,657
`
`
`
`
`
`Ex. 1019 (Pet. 25): The cited portions relate to the design below. Pet. 25
`
`(citing Ex. 1019, 6:60-62, 7:40-42). The first passage describes an “RF blocking
`
`filter” 32, which “when designed properly, can eliminate or reduce substantially
`
`RF current flowing to the DC source 30.” Ex. 1019, 6:58-62. The second passage
`
`reiterates that filter 32 is “to block transmission of RF power from coil 6 to voltage
`
`source 30.” Id. at 7:40-42. In the design below, the coil 6 is connected to both the
`
`RF power 16 and the DC power 30. See id., Fig. 1, 7:3-6. This differs from the
`
`challenged claims, where bipolar pulsed DC power is provided to the target and RF
`
`power is provided to the substrate.” See Ex. 1001, cls. 1 & 2.
