Introduction
Patent Search Tools are platforms designed to help users find existing patents, analyze prior art, and evaluate innovation landscapes across global databases. These tools are essential for inventors, legal professionals, and R&D teams to determine whether an idea is novel, avoid infringement risks, and understand competitor activity.
