Appeal No. 1998-0225
Application No. 08/503,817
appellants and the examiner.
OPINION
The examiner takes the position that Takeuchi discloses the subject matter of the
independent claims but for the specific details of the transmitter for sending
magnetic/electromagnetic waves and that the magnetic impedance element has an
impedance which changes in accordance with the detected modulated magnetic field.
The examiner then relies on Salisbury for the teaching of the specifics of a transmitter
portion of a magnetic field generating system and concludes that it would have been
obvious to combine Takeuchi and Salisbury to provide the undisclosed modulated
magnetic field of Takeuchi with a modulated magnetic wave. Finally, the examiner relies
on Albee for a teaching of a variable negative reactance circuit 24 and contends that it
would have been obvious to add the negative reactance circuit of Albee to the reception
portion of the modified Takeuchi wireless data transfer system for the purpose of obtaining
a frequency independent transmission system.
Appellants contend that none of the applied references discloses the claimed use
of an MI element.
The examiner indicates that neither Takeuchi nor Salisbury discloses the claimed
MI element in a receiver wherein impedance is varied in accordance with a modulated
characteristic of the magnetic field, relying on Albee for providing this claim limitation.
