Patent for Sale:Circuit Breaker Based on Leak Current Detection
Primary Application of the Technology
South Korea recently revised their safety standards by setting the leakage current threshold to be 6mA . The present technology was devised to meet such tough standards.
Many other countries are expected to follow suit to the Korean standards in the near future, and thus will end up replacing their circuit breakers with those that can meet the new safety standards.
A quick estimate based on the number of breakers used in private homes in Taiwan, Australia, China, Europe, India, Sri Lanka, US, Russia, Hong Kong, and South Korea shows that the gross sales can be as high as $6B. This number will jump to more than $10B when industrial usage is added to the estimate.
The seller may consider selling these patents individually.
