There is no known fixed amount. Standards groups shy away from that as it could be considered anti-trust violation (major corporations agreeing on a certain price together). They simply create a standard and let the patent situation become whatever it becomes. It is a terrible situation for new companies wanting to get in the business. They are hugely disadvantaged.Hi
If LTE is a standard then there is a known and fixed amount to pay. Can a company refuses payment? OR is i simply a ploy .. I see this as a dangerous move from Samsung. Such use of a "standard" dilute the notion of standard... That would be like Sony refusing their standard to Toshiba for BluRay players ...
As to refusing to pay, you can of course until the moment you get served with a lawsuit and lose
As I noted in previous response, almost all standards groups have a condition of participation called RAND: Reasonable and non-Discriminatory licensing. This means that the price must be the same for all licensees and you cannot refuse to give them a license. So there is no danger of Samsung not providing a license to Apple. The reverse however is not true. Apple has no obligation to give a license to Samsung for look and feel of the iPad, gesture commands, etc. They could literally shut them out of the market although doing so when you are a dominant player could cause anti-trust scrutiny. Then again, it is unlikely that US government would get involved to protect the rights of a Korean company.
