Aucbvax.2492 fa.works utzoo!decvax!ucbvax!works Fri Jul 31 03:55:50 1981 Patents etc. >From Joe.Newcomer@CMU-10A Fri Jul 31 03:48:00 1981 I was advised some years ago that building any patentable device for personal use is legal. However, you may not sell them, or give them away. The fuzzy area is the definition of "personal use"; if I use something in a business, even if it is on my "personal" workstation, the issue is resolvable only by extremely expensive attorneys. The degree of personal-vs-for profit use also affects how much it is worth to the owner of the patent to prosecute. joe
