The new XWING Mesh
Fonts are a special confusing case, I think. They're utilitarian objects,
which has hampered their protection in the past. Shades of people claiming to
copyright or patent the letter 'e'.
I've encountered a counter-example to what you're saying. Lucasfilm *did*
contact us because they claimed that some of the space-ship models in our print
advertisements were in fact properties of Lcuasfilm. No names were attached to
the models, in fact, the images are quite small and lost in the sea of
thumbnails, each less than 1/4 inch square. They circled the offending objects,
including the Death Star (meaning their properties probably encompass apples,
oranges and plums) and several space ships that were pure invention, not
related or even inspired by Star Wars. The letter we received was not from a
lawyer. I do intend to remove the use of their specific names from our
catalog, and turn them to generic descriptions – and I may refrain from using
any space-ships in future ads.
