I'm unfamiliar with that case, sorry. If you'll excuse me for doing so, may I give you the SY Primer on Patents? If all this is too obvious and familiar to you, please excuse me. And the above disclaimer applies: I'm not an attorney.
1. A patent is a license to sue, no more and no less. In exchange for telling the world everything about your invention in enough detail for anyone in your field to duplicate it, you have the right to sue anyone who makes/uses your invention without your permission for a period of time (normally 20 years).
2. Suing is damned expensive. If you're a small guy and the guy ripping you off is a big guy, your chances of prevailing are about equal to that of hitting the lottery.
3. In litigation, the lawyers always win.
If you want to have specifics about my own experiences or just discuss things, feel free to email me.
Skippy,
To quote Grahame,
I reckon most people would not hold the same view of tubes if the visuals were boring, and if SS gear can sound better, then tubes ought to be consigned to museums because of thermal, energy and reliability/endurance issues.
I admire the the intellect behing the Pass amplifiers, and the ones I heard were very pleasing sonically, but again the energy efficiency issues deter me, and I am not willing to compromise on that important factor.
I did not set out to be provocative, and gave some of my view points and some of my experiences.
I suspect that some tube users are locked into a nostalgia trip - I much prefer modern sound reproduction when done correctly.
I also realize that tube electronics do give a particular sonic character that can be very pleasing, but I still do not regard this as the sonic truth.

Yes, I am aware of that and is why I wrote
Threads evolve around here, and whilst probably to most of us tube amplifiers are intrinsically visually fascinating, to my mind that is a criteria of little importance wrt sonics, and the sexiest looking tube stages on earth still will not sway me if the sound does not please.

Yup, fully understanding of those points.
You mean that if you are the criminal, then if you have suitable lawyers, then you can do what you like.
Yeah, ain't that the truth - I think I recall Dame Edna describing lawyers as being lower than a snakes armpit....
Yes, thankyou.
It will take a day or so, and I'll get back to you - I am interested to hear more of your knowledge.

Hello Bas,
I'll bet you are good at cryptic crosswords!
No just reiterating that if your ears are at all important or useful to you. then stay away from 136dB levels - 0.7sec exposure is enough to cause permanent damage.
Sound pressure is sound pressure is sound pressure regardless of black arts practised in its production/reproduction

Hi John,
I guess you won't steal my patent or at least use it because for you it is to late?
By the way..a few iterations down the line and my amp is now good enough that I can listen to a classical CD on my amp without whinging!
in fact I am very happy with the way it is working now. The final change that made an inordinate change was biasing the heater supply up for my driver. Actually that was not the only thing. I measured the voltage on the 6n1p....was 5,6volts 
so I wired it up to my filament transformer that was meant only for the upper tube of the mu-follower. And voila..
Cheers,
Bas
Did I tell you that I also added a 1uF auricap to couple the driver to output tube? I read Allan Kimmel again..and he said that a bigger than usual cap is needed in order for the low impedance to be coupled to the next stage...

Come to think of it ...the improvement in sound is probably mostly because the driver just got a filament transformer that was not coupled to the rectifier tube and output tube..and not so much that it was biased upwardly...
To summarize...don't know really wat it was..but I'll tell you this..from now on a key thing like the driver is getting it's very own little filament transformer in future amps.
In fact the improvement is so great that I was thinking of creating a new post on the subject. I mean...it is just a IDH tube it should hardly matter how you power the filament?? Why on earth would the HT and filament winding apparantly influence each other THAT much.. I have found other reports that corroborate what I've heard..

I agree with the SPIRIT of the text not word for word. Remember theire native tongue is not english.
In my own words...larger soundstage..more separation...but above all a certain rightness I can't explain. ..now I don't want to get in to "Aural Matrix" territory because then Brett won't answer any of my questions anymore
Why it works? Dunno
