If the innovations have no points of similarity to the other device,
then the innovations should be subject to patent, or trademark, or
copyright, or whatever legal thing would apply. The innovations are one
thing, the overall device is another.
I think where it gets interesting is at what point an innovation constitutes a "modification?"
Consider a cake recipe that`s been copyrighted. I come along and add to
it shredded carrots. I`ve modified the recipe, making an innovative
decision on my own. So? The bulk of the recipe remained the same. I see
no difference in this and the plagiarism laws assigned to music.
But suppose I start with a ballpoint pen, using patented technology.
This time my innovation is in the way the ink is pushed to the nib. I
develop a miniscule nuclear reactor and put it into the original
`Parker` ballpoint.
At what point does an innovation fundamentally change the design of the
original device? If there aren`t any laws on this, then I`d be
surprised. But to say that the point is determined by "well...anyone
can see! It`s obvious!" is bad law, in my opinion.
