Yes, copyright is a real hornet's nest.
I remember reading an article in Building magazine many years ago on the subject of copyright where one large housebuild
er tried to take another to court because it had copied one of its designs. But because the defendant had slightly altered the design it got away with it.
So for example if I put my Swordsman drawings
on Ebay, which were based on the kit drawings
, I shouldn't have any problem as I have made a number of alterations. I won't be of course as I've only drawn enough for me to build
, they are not full working drawings
and I'm not interested in doing that.
Where that guy on Ebay is at fault is that he is blatantly copying the original kit drawings
with Aerokits on them rather than redrawing them - not that he has the wherewithal!
