Hi Robert,
I checked USPTO and found you hold 5 patents.
I like to listen to your advices, experiences and lessons all ears.
Several things for me to file patents are:
1. The circuits must be novel, and it will be applied in the industry
without doubt.
For example, they must be dramatic advantages over current ones in one
of following respects: speed, performance, saving power or saving
logic.
2. The 'novel' circuit must have potential buyers to make money.
3. History will keep your invention as a record and the circuit can go
into textbooks.
But basically, making money is the most important factor to file a
patent.

Well, *dramatic* advantages are not really necessary; making the
device more useable or practical is sufficient.
Check my website oil4lessllc.com and look at the Mosley patent and
then at the two i put into PD as an example.
If one wants to be nasty, the item patented does not have to be
practical, does not have to be buildable by ordinary means.
Hell, i have seen numerous patents on things that were obvious to
even those *not* skilled in the particular art (ie: legally speaking the
patent should not have been awarded).
And i have seen patents that were almost exact copies of one another
(up to three!).
One patent i saw was intriguing; it purported to be a patent on a
plastic coated bike sprocket, but really was a chemical patent "hiding"
in a different classification.
Do your own patent search for background and interference (of idea);
patent lawyers are very expensive and if the one chosen lacks a
background in the field of art that your idea covers, then their search
will not be as wide or deep as needed.
The Patent Clearing house in Sunnyvale CA is the best in the nation -
mainly because they have *all* of the cross reference material that is
available.
If and when you do go for a patent lawyer, make sure that they do
have the relevant background (5 years or more).
And have the whole patent written up; even format it the same way as
required for submittal.
Have those you trust go over wording of the claims, suggest added
ones, check spelling, etc.
If there is a term commonly used in similar patents but is not
standard english, use the "patent-ese" not English.
For example, in the pump patent, note the term "depending" is used,
where English would use "descending".
