For example, if I have an invention with different implements, can I spit it into multiple patents that each of them doesn't contain others information?
The reason may be to keep the competitor confused. For example, the competitor will think the scope of one patent is very narrow, while the other patents are kept in secret to gain advantages later.
One thing I can think of is some rules, e.g USA says that the inventor must reveal the best approach he knows. But since different implements are similar, without the best one, this can be avoided.
I think in practice it is easy to do, if the inventor can accept lying that other implements came to him at different time then that is normal, even there is a best approach. But what about the law if the inventor must be honest?
Another method I can think of is splitting the invention into multiple inventions by redefine the scope of the invention so they are not a single invention but multiple inventions.
Is there any obstacle for splitting a single invention into multiple independent patents without relating to each others?
