Hello!

I have just read some of the patent info and it is very interesting. It is a 
very expensive situation to get a patent quickly. As you state, some things are 
stolen by others and just a small feature added and resubmitted.
I was interested in getting a patent on a device I developed and contacted the 
patent office.  This was about 30 years ago.  I was informed that I could 
initiate a search but it would be quite expensive to go through all the 
material necessary to get a complete patent.  Also, they provided (at that 
time) information on the safety of your work while in the patent search.  I 
don't know if this (following) is still in effect or not but here is what they 
told me
#1 DATE and Copy all your drawings, charts , photos, etc. Pack in a large 
manilla envelope and mail (by first class) to : INTENT TO DISCLOSURE DEPT., 
Bureau of Documents, Washington DC.  ====   They would keep the envelope for up 
to 3 years while you were completing your processes. If in the case someone did 
try to use or steal your product, design, work, or ?? You have the oppertunity 
to bring them to trial and call or write the Disclosure Dept. letting them know 
that you needed your material. It would be returned to you UNOPENED, which you 
should not open until it is your time to provide evidence at the trial. Present 
the unopened envelope to the Judge and anything inside is proof at that date 
(being same as on envelope) would be proof  of your property. 

I hope this is of some help to anyone interested, being a newcomer I am not 
accustomed to all the proceedures and hope this post is not in any way 
obtrusive. (an no, I didn't get the patent! was too expensive at that time) The 
same idea came out about 15 monthe later with just a little change of my 
design! I had made the mistake of talking to several people while in testing 
the unit when I should have kept my mouth shut!
Regards,
Roy
