Electronics patents are granted for improvements in a number of areas, some of which are so large (for example computers, telecommunications) that they are now considered different topics. Electronic patents are granted for both conventional analog circuitry and for digital devices, as well as semiconductor devices (IC Chips), and numerous related technical fields. The number of patents granted each year on devices in the electronic arts, and in the numerous offspring technologies, easily numbers in the hundreds of thousands, even considering the US Patent and Trademark Office alone.
In addition to work on older analog circuitry, Barber Legal can offer experience in modern semiconductors, systems design and various specific applications (seismoelectric prospecting, IR radiating materials, etc). Of course, no patent attorney can claim to understand a new and original invention like the original patent attorney. Being easy for clients to work with is a hidden strength of our law firm.
We've included as examples abstracts
taken from patents previously granted. Some of these patents were close to history, some are unknown,
a few were chosen whimsically. Note that these are not chosen for being patents
done by Barber Legal, we're not advertising here, nor promising that "we can get you a patent like this",
nor are we trying to take credit for the work of other registered patent attorneys: we've even included the names of
other firms in our excerpts and we always urge potential clients to call around to compare our prices and those
of other firms. What we are doing is giving you an idea of the sorts of things that have been done
in the past by inventors and patent attorneys around the world.
In the excerpts on this page, readers will note that the inventors filed US patent applications
claiming priority based upon patents originally filed abroad. This is an example of patent applications
"incoming" to the US from another nation. Needless to say, many US inventors file "outgoing"
applications abroad every year. For a more on international

Abstract:
An analog video signal selection circuit which selects one of video signals and synchronous
signals from two different channels, including: a mode selection means for generating a
first channel selection signal or a second channel selection signal in a manual mode or
generating an automode selection signal in a auto mode; a data selection means for selecting
one of the first data of R1, G1 and B1 received from the first channel or the second
data R2, G2 and B2 received from the second channel and providing the selected data
as R, G and B output signals in accordance with the first and second channel selection
signals generated from the mode selection means; and a synchronous signal selection
means for selecting one of a first synchronous data of horizontal and vertical
synchronous signals from the first channel and a second synchronous data of horizontal and
vertical synchronous signals from the second channel in accordance with the first and
second channel selection signals generated from the mode selection means.

Abstract:
A semiconductor integrated circuit enables a drive circuit and a reception circuit
to be constituted. The drive circuit drives long wiring in high speed while achieving
realization of reduced area when large capacity of load is driven. The reception circuit
receives this signal in high speed. There is provided an inverter within the drive circuit.
An n-type MOS transistor is adopted as drive transistor. Drive power of the n-type MOS
transistor is larger than that of a p-type MOS transistor. It is capable of driving signal
with large load in long wiring such as bus line. Thus the drive circuit is realized in that
the drive circuit drives the long wiring in high speed while achieving realization of
reduced area. Further, it is capable of realizing a reception circuit suppressing
through-current during the time period when the signal is changed.
