Siemens Nixdorf has sent out letters to 70 OEMs in Europe asking them to respond to patent claims about monitors.
The European patent - number 0624272 - relates to monitors, a Siemens Nixdorf spokesperson confirmed today. She said: ?We?ve sent a letter to various European competitors, asking them to set up negotiations with us over our protected Siemens patent. The patent relates to low power modes for monitors. It dates from 1995 and is valid in 10 European countries,? she said.?
?Our company is trying to get mutual agreement from the companies,? she said. ?They were asked to reply before 15 September.?
But Keith Warburton, executive director of the Personal Computer Association (PCA), said his members were angry at the move. He said that some of his members had received the letter from Siemens-Nixdorf and did not need the aggravation of having to pay licence fees for some system which they thought was part of the normal Bios in PCs.
Siemens-Nixdorf said that it was not seeking to get damages from smaller OEMs but the spokesperson added she was speaking to a number of larger ones.
As yet, she said, Siemens-Nixdorf was not taking legal action against any of the companies it had mailed.
