Toyota's Hybrid Synergy Drive (HSD) is a great technological achievement that ecologists enjoy all over the world, but is it an original Toyota invention?
Intellectual property is a taboo subject. We know that Microsoft's first operating system was not created by Microsoft, because it's a textbook case. But very few people know that the transmission of the first generation Toyota Prius (1997) was not invented by Toyota, but by the equipment manufacturer Aisin, which is true that Toyota is a shareholder. The case that makes the news today concerns part of the HSD transmission of the Prius II and Lexus RX400h, which would take a patented technology by a European company, Antonov-Transmission, under the patent No. EP 0414782.
