nVidia sues 3dfx
On Monday, August 28, nVidia sued 3dfx for alleged patent infringement. nVidia wants to ban the production, sale and import of graphics cards by court order 3Dfx. This should affect the Voodoo 3 and the current Voodoo 4/5 cards with VSA-100 chips, i.e. almost the entire range of products from 3dfx.
nVidia also wants to claim damages. All of this together could mean the end of it for 3dfx if nVidia gets away with all of the demands. Thus, nVidia would be able to build a quasi-monopoly, as the main rival would be eliminated. The patents are a possibility of fast memory transfer and the conversion of virtual into physical addresses. The patents can be viewed publicly at the American Patent Office. The patents in question are as follows: 5 687 357, 5 721 947, 5 758 182, 6 023 738 and 6 092 124.
