The statement from ROL at the top of this article states that they took out the licence from E14 in March 1999. A five year licence would therefore have expired in March this year.
Does anybody think that ROL have a valid claim that CTL have breached the terms of their RO4 licence from ROL, which they needed to be able to sell RPCs with RO4? This will almost certainly not allow development of the OS, or selling into any but specified restricted markets.
I think it is unfortunate that the situation has come to this. ROL and CTL will get their heads together PDQ and sort this whole business once and for all if they have the future of RISC OS at heart.
