VIA said Intel's top-of-the-line Pentium 4 processor, and the 845 chipset that supports it, infringe on company patents. ``Not only Intel has chipset and CPU (central processing unit) patents. We have a lot of patents also,'' VIA Vice President Ted Lee told a news conference. VIA also accused Intel of anti-competitive behaviour, related to allegations that the U.S. firm has threatened Taiwan's motherboard makers with legal action if they use VIA's products.
