I have not looked into what Tim's patent says but I doubt if it is a
supportable patent except in a very narrow way. That is often the way with
patents. One has to define them so narrowly that it becomes easy to
circumvent them. Also, one has to be willing to go to court to support your
claim and that is risky expensive business. 

Having been through this business myself both as an expert witness in
support of a patent (the case was lost - maybe I wasn't expert enough) and
also as a patent seeker the costs of a patent just aren't worth it unless
one really has a great idea that will make tons of money. My lawyer says
most people get patents just for bragging purposes. He calls them vanity
patents.  

I doubt if the sponson concept itself can be patented. As Keith points out,
the basic idea is older than Moses.
