What was the significance of Tesla filing his essential polyphase patents in 1888?
Answer
It established the intellectual property foundation for the successful power distribution system.
The filing of the polyphase system patents in 1888 was a pivotal moment for the electrical industry. By securing the intellectual property for a complete system—covering generation, transmission, and utilization—Tesla provided the legal and technical framework that allowed his design to dominate the marketplace. This patent protection allowed companies like Westinghouse to confidently build the infrastructure necessary for a global power grid.
