Toyota launched the Prius in Japan in 1997, and it became the most recognisable hybrid car in the world. A small Delhi-based auto-components business registered PRIUS as its trademark in India in the early 2000s. Toyota brought the car to the Indian market around 2009 and 2010, and then went to court to stop the local firm using the name.
It lost. In December 2017, the Supreme Court of India ruled against Toyota on the Prius mark.
The IP move
The case came down to a choice between two competing doctrines. Under the universality principle, a mark that has acquired a global reputation carries that reputation everywhere. Under the territoriality principle, reputation must be established in the specific territory where protection is claimed. The Supreme Court applied territoriality.
That reframed the question entirely. It was no longer whether Prius was famous, because plainly it was. It was whether Prius had acquired goodwill among Indian consumers at the time the defendant adopted the name, some years before Toyota sold a single one here.
On that question the evidence fell short. India in the early 2000s was not the connected market it later became. Coverage in foreign automotive publications, some limited Indian press mentions and the general awareness of a global product were held not to establish that a substantial section of Indian buyers associated the word Prius with Toyota at the relevant date. Without proof of goodwill in India at that moment, a passing-off action had nothing to stand on. Toyota held the world's attention and lacked the one market's evidence that actually mattered.
The takeaways
Rights are granted country by country. A brand that is unmistakable abroad can be legally available at home to whoever files first.
The date that decides the case is usually the date the other side adopted the mark, not the date you noticed them using it.
Reputation has to be proved with evidence of local recognition, and that evidence is far easier to gather as it accumulates than to reconstruct fifteen years afterwards.
A company can hold a very large global portfolio and still have a hole in the single market it is about to enter.
Filing ahead of launch is not premature. It is the only version of this that is cheap.
The lesson for your business
Before you enter a new market, and equally before somebody enters yours, establish what you actually own there. An IP position audit maps registrations against markets, surfaces the gaps, identifies prior adopters already sitting on your name, and tells you what evidence of use you hold and what you would need to assemble. Toyota's difficulty was never that Indian law was hostile. It was that the gap in its position only became visible at the point where it had already committed to the launch, which is the most expensive moment to find out.
