I have a great idea for a product, device or method...

What can I do to protect it?
As simple and direct as this question sounds, the
answer can be quite confusing.  Generally,there are
four main types of protection for one's ideas and
creations -- often referred to  as one's
intellectual
property.
These types of protection  are:  patents,
copyrights, trademarks, and trade secrets.

counsel of an experienced intellectual property
lawyer to give specific advice that would suit your
creation.
