32 Final Written Decision original: Final Written Decision original

Document IPR2022-00573, No. 32 Final Written Decision original - Final Written Decision original (P.T.A.B. Sep. 11, 2023)
Patent 7,825,537 B2 characteristic of said time varying electric current) responsive to the ‘feedback signal’ to achieve and maintain operation at the ‘resonant’ frequency of the coupled inductor system,” where “the ‘feedback signal’ from the sense coil constitutes ‘at least one parameter indicative of an efficiency of power transfer from said base unit to said target unit.’” Pet. 55.
As discussed above with respect to elements 1.3 and 1.4, Flowerdew teaches that “[a]pplication of a variable frequency is predicated on the basis that the high efficiency achieved by driving a resonant system is needed for effective operation.” Ex. 1007, 13:30–35 (cited by Pet. 55).
Petitioner also directs us to Flowerdew’s teaching that a “‘free running’ state, where no secondary unit 304 is present, can be detected and the power output reduced to a predetermined level or applied periodically to determine whether an item has been placed on the charging surface.” Id. at 13:18–21 (cited by Pet. 67).
Petitioner contends that “[i]t would have been obvious to modify Flowerdew in accordance with Jang’s suggestion to regulate the drive frequency based on a feedback loop that compares a measurement of the current through a primary coil to a constant reference value.” Pet. 68.
As discussed above, the Baarman Provisional Application teaches that “[u]sing feedback from the secondary, such as the sensed voltage and/or current, ... the duty cycle may be adjusted to provide additional or less power to meet the desired goal.” Ex. 1009, 16 (cited by Pet. 8).

31 Other Hearing transcript: Other Hearing transcript

Document IPR2022-00573, No. 31 Other Hearing transcript - Other Hearing transcript (P.T.A.B. Jul. 31, 2023)
As we have stated in the petition reply, Baarman would be entitled to its priority date through the Drinkware test to establish that the provisional provides support for the claims in accordance with one.
And our expert further testified, as we say -- as we show in the bottom of slide 12, that not only would this combination optimize the power transfer as desired by both of the references, but using the magnets would have it be a user friendly method of positioning and reduce the likelihood of errors.
MR. PETRSORIC: Okay, here I think may be the disconnect, Your Honor, is the fact that with respect to claim element 1.4, they identified that the time -- the parameters obtained from current sensor 322 and the RC circuit, and that's on page 25 to 26 of the petition.
I'll note that the expert declaration is substantially similar, if not parroting what's in the petition and under the Director's precedential decision in Xerox v. Byte Mark, there's a question as to how much weight, if any, should be accorded to it.
MR. PETRSORIC: The art -- the Baarman ‘392 that the petition relies on for claims 5 and 16 is a mechanism to detect if the voltage and current at the secondary coil, which is being fed to the battery, is over an acceptable value.
