Dean Did you sign any kind of agreement when you bought the plans, or is there anything posted on the website or in the promotional materials you reviewed prior to purchase that put you on notice that you couldn't sell the plans? If not, then you are free to do with them as you wish, including selling them. If the notice or warning is only contained in the materials you received after you paid for them, then it has no legal effect, since you would have to have been advised of the restriction BEFORE you bought them for it to be part of your purchase contract. In other words, a seller can't make a sales contract under certain terms, then add to those terms unilaterally after the sale is effected.
Remember that many statements are made in the course of business intended to intimidate others, but without legal effect. For example, the ticket you purchase at the county fair says, "No responsible for injuries, etc.," but of course that language has no significance. Of course the fair is liable for the negligence of its employees. But there's no law against making such a statement, even if it means nothing, and it's worth the cost of printing the back of the ticket with the disclaimer if it dissuades just one person from suing. Whether or not you built a plane from the plans is actually irrelevant; the issue is whether you agreed not to sell them before you bought them. I hope this is of some value. Max
