Oh my, I had no idea how many tubists held day jobs as IP attorneys. Do you all truly purport to mount a legal defense against alleged patent infringement with so little actual evidence? I am impressed because that is such an arcane and complex area of law that my business attorneys have always given me references to specialists when I needed help with these matters.
As I see it there is one thing in question in this thread (well, the part about personal/business integrity) and it has nothing to do with whether the "Patented Z Valve" is similar enough to any earlier design, whether any other company had an even vaguely similar design or whether the TNFJ has officially anointed Wessex Tubas as their official Importer of Chinese Built Tubas.
IMO the only germane questions are:
1. Did Wessex Tubas or their agents make any claims to hold patent(s) (in any country) for their fabulous new invention which was referred to in their sales efforts as the "Z Valve"?
2. If so, did Wessex Tubas or their agents actually hold patent(s) for said bit of hardware design?
Since Wessex Tuba's agents frequent this forum these should be easily and quickly answered, should they not?
While I have no ax to grind, I have seen evidence to answer question #1 above and can only wait for the answer to question #2.
So to many of the above: Please present your arguments as to why any mention Miraphone or other extraneous BS is anything other than obfuscation or shut up and go home.

Oops I should have read recent posts when I returned home before responding. Seems that "DP" has succinctly addressed the salient concerns:
