Intel’s Softphone/voip patent… and CU SeeMe
Turns out Intel has a patent on VoIP phones on PC’s. You can check it here. It covers basically anything that does Voice over IP covers it. It was applied in 2000 and granted in late 2006.
Problem is… there’s prior art called CU See Me. It was origionaly video only, but audio was added in… 1994 (for Macs, 1995 for Windows).
Whoops, US Patent Office screwed up again.
