Yes folks, Lochaber Highland Estates (CI) Limited soon to be Highland Titles Limited have indeed trademarked Laird Of Glencoe on paper, cardboard and goods made from these materials.
So you can call yourself Laird Of Glencoe just don't write it on anything or they could sue you! There is no indication on their website that this is a trademark, nor any indication that buyers of their plots have any right to use it or any restrictions of use. Oh, that also proves quite conclusively that they themselves don't consider Laird to be a real title at all. Talk about shooting yourself in the foot!
