The cache is not at the above location, but you will need to drive by the building at these coordinates to solve the puzzle.
To solve this problem, you're going to have to learn a few things about Patents.
Go to www.google.com/patents and look up patent number 6691032 (just type in the first number and click on the first match).
This patent grants the assigness a monopoly to the claimed invention only in the United States. As far as I am aware, there is no equivalent patent granted or pending for Australia,
The ultimate question is 'What is the invention that is being patented?'.
Try to guess what product falls within the scope of this patent (the name of the assignee might give you a clue). Its trademarked name isn't actually mentioned in the patent, but I've written the answer down at the top of the logbook.
The cache is hidden at S 35 20.ABC E 149 05.DEF.
The number of times 'geocaching' is mentioned in column 1 of the patent (page 27 of the PDF file) = A
The Patent Factory (given in the disclosed coordinates) is located in ????????? House. The numerical value of the first letter (A=1, B=2 etc.) = B
The number of times 'geocaching' is mentioned in column 8 of the patent (page 30 of the PDF file) = C
Claim 22 is dependent upon 'a system according to claim D'
The number of man-shaped figures depicted in Figure 6 = E
The claim number that details 'A system according to claim 1, further comprising: the trigger triggering at least one user-definable event upon at least one of an entry into or exit from one such zone of influence." = F
Here are the checksums. Please use them as the wrong coordinates might take you somewhere you are not welcome.
S=18, E=31
The log is packed in tight, so bring along tweezers, a toothpick, piece of wire or similar for extraction.
