There is a lot to this case but information is scarce. Klein had a patent relating to oversize aluminium tubed frames. Klein sued Cannondale. Klein's patent was ruled invalid. Supposedly, at least Bill Shook and Roger Durham testified as to prior large tube bikes they had built. Plus the MIT class. Let alone every other builder that had used a big thin tube and could have provided prior art. Granby, Bates etc. The patent was apparently held to be invalid.

If anyone can point me toward the patent number or a citation to the case(s) I can provide more details.
