Getting back on topic...
Of interest, I think, is the fact that the judge in the Gibson v. PRS suit is in Nashville (Gibson's home town, these days), though it is, as yet, just a denial of a summery judgment. The actual trial, last I had heard, has not happened yet.
As I have said before, the case is bogus, in my professional judgment. The instruments are VERY different in shape, if you have any eye for the design of a guitar. There are certainly very few guitarists who have trouble telling the difference.
The one I really like, though, is when Gibson tried to sue Heritage. For those who don't know the history, Gibson used to be manufactured in Michigan, and when they moved to Nashville, they sold all of their jigs, fixtures, and machines to their employees, who started the Heritage company. Heritage immediately started making pretty much the same guitars they had always been making for years, and shortly there after, Gibson sued. The ruling handed down, which unfortunately has no bearing on the current cases, was that when Gibson sold their jigs, fixtures, and such to their employees, they also sold an implied warranty that those items would be useful. Heritage had to change to a different headstock, but beyond that, Gibson was told to go stuff it. Personally, I liked that one. Heritage, to this day, makes a far superior instrument, in my opinion. They are the original factory, the original employees (or they were, though by now most of them must have retired), and they made some improvements on the Gibson designs (For instance, they tap tune the tops on their arch top guitars, something which Gibson has never done. While this is of dubious value on a flattop, I think it does make a difference in archtops). And because the name is not Gibson, they cost about half, last time I checked.
As for the headstock thing, my understanding is that Fender chose not to go after body shape, though why I am not sure, nor am I completely confident that is the case.
