    Here is proof that persistance pays off, even with the Patent Office.
Normally when you see an announcement for a new patent, it lists the filing
date of the original application, sometimes with an additional date for a
continuation filing or an abandoned filing.  Occasionally there are more
than a few dates, representing a couple of continuations or abandonments.

    Here is one of the few I have seen that is the alltime continuation
prosecution.  It is a patent awarded to Gilbert Hyatt (the microprocessor
patent guy) that started prosecution in the early seventies, and twenty
years later finally was awarded.

    My hat off to Mr. Hyatt.

ABSTRACT: 
A filter processor provides improved capabilities and reduced complexity by
inputting and processing lower resolution signals and by generating higher
resolution filtered signals. In a preferred embodiment; an incremental filter
processor generates incremental input signals, performs incremental
processing, and generates multi-bit filtered signals. Input signals are
received from radar, sonar, seismic, or other sources; are processed by the
filter processor to generate filtered signals; and can be post processed by a
post processor. In a preferred embodiment, the input circuit is a serial
input and parallel output circuit, such as a delay line or a CCD; the filter
processor is an incremental fast Fourier transform processor; and the post
processor is an incremental frequency domain correlator. Other post
processors include a frequency domain integrator and an RSS post processor to
convert coherent signal samples to noncoherent signal samples.
