ST,
read everything the manufacturers in a given field have in their
literature. On their website... Trico and EFD are two of the "big
players" in Dispensing.
Reading patents at www.uspto.gov can be VERY enlightening...
Search on "dispensing EFD"... (I think that's what I ended up using)
Note that many patents are expired and can be used freely. Many
others can be licensed. Some will just give you ideas...
IMO, don't mess with copying an unexpired patent without permission!
It is a FALLACY that you can USE a patented idea for your "own
personal use" without selling it to anybody. While you might "get
away" with this, it's NOT legal.

P.S. many mfrs. will list their patent numbers on their website. Even
expired ones. To "scare" you away... Read 'em.
