Are your queries directed to me? If so:

"I thought it is now a matter of no more lawsuits ( at this time ) ???"

"At this time" is not forever.

"What's the point of looking at these other players in IT ?"

 The implied answer is in your next question.

"Are these IT companies using the same tech or something unique to their own inventions?"

That was the point in my post......unless you mean something else
