What This Patent Covers

This patent, comprising 6 claims, protects both the structure of the rail straightening jig and the method of using it. It specifically claims the core technological aspects by defining the jig's contact surface with a 'downward slope' whose 'angle is determined by the rail's curvature' and a 'body length determined by the maximum load'. This robust claim design, developed by multiple experienced agents, suggests a strong patent less susceptible to invalidation, offering licensees confidence for business development.
