Appeal No. 1999-2070
Application 08/611,899
Emitter Array Integrated Distributed Amplifiers.” Brief at
page 8, lines 5-8. Appellants further state that although
field emitters are used in Gray and claimed by Appellants,
Appellants’ use of field emitters does not involve
amplification. Brief at page 8, lines 9-12. Appellants next
compare Appellants’ invention to Gray and state that
Appellants use a diode structure while Gray uses a gridded
structure. Brief at page 8, lines 20-21. Appellants assert
that Grays’ grids create a tetrode like structure that is not
present in Appellants’ device. Brief at page 8, lines 12-16.
In fact, Appellants continue, that then device does not
require grids for operation at all as in the case of Gray.
Brief at page 8, lines 18-21. Appellants, while conceding
that Gray uses dielectric materials, contend that the
materials are used for a different reason. Brief at page 9.
Finally, Appellants summarize by asserting that the devices of
Gray and Appellants are fundamentally different because Gray
claims an amplifier and Appellants’ invention is a voltage
limiter. Brief at page 10, lines 3-5.
The Examiner responds that Appellants’ arguments are not
persuasive because the recited limitations of claim 1 are met
