A utility patent provides a significant amount of intellectual property protection for inventors. The utility patent only protects those claims in the filing itself, so great care must be taken to ensure that the claims are broad enough to actually protect the inventor's product space.
Utility patents can take many thousands of dollars and many months or years to be granted. In most cases, there will be several discussions or negotiations with the patent office before a patent is issued.
Be cautious. A patent simply grants the patent owner the right to take legal action against others who violate the patent. It can cost a significant amount of money to defend a patent in court.
