Actually, this isn't a case of a submarine patent.
The patent itself was registered in 1993 (US patent 5,252,499 ‘Wide band-gap semiconductors having low bipolar resistivity and method of formation’). When adoption of the technology really started kicking off in the early 2000s, she asserted the patent, and various companies settled on the basis that she'd be instrumental in developing the technology, and rightfully held a valid patent.
As long ago as 2002, various semiconductor companies have complied with the request for payment on patent royalties, so she has definitely been asserting this.
I'd make an assumption that the 'Big Boys' (i.e. Sony, Toshiba, Sharp, LG etc.) have seen this as something they can avoid by merely using legal methods to avoid having to pay legitimate fees (or that they've perhaps falsely assumed it was covered by a cross licensing agreement with another of the Big Boy players).
So, my impression is that it's a perfectly valid case, and has most likely followed normal channels of requesting royalties (as some companies have paid up over 6 years ago on this), been stonewalled and rejected by the big players before finally hitting the courts in an attempt to avoid being rolled over and told to go away and stop bothering big business with petty things like an actual inventor holding their own patent that just happens to be key to what big business is doing.
