I found these:

http:// Supreme Court basket case

http:// Patents on line , free (there is no free anything)

See the co. name in the 2nd link, about 1/2 a pg. down. You could ff up on this if you wanted to create an account at this site, ("it's free!"). There might be more about Hallock. If you do let us know. That's all I could find.

I can only hope that the blueberries will be ok.

Take care
