What is Patent Pending?

Thanks for the great question Alvin. Patent pending means that someone has applied for a patent on an invention and is waiting to see if the patent is granted. Manufacturers use it as a warning that a patent may be issued that would cover the item and that copiers should be careful because they might infringe if the patent issues. You can only use the term patent pending if you have applied for a patent (provisonal or non-provisional). You cannot use the term patent pending if it is not true.
