A patent dispute in Japan has just put Google in a tough spot. The company is now officially banned from selling its Pixel 7 series in the country, following a court ruling that it violated a key LTE-related patent held by Pantech, a Korean mobile firm that’s now focusing more on intellectual property than making phones.
The ruling, reported by ETNews, centers around signal mapping technology used in 4G LTE networks. Specifically, the patent involves how base stations send acknowledgement signals (ACK) to smartphones — something that’s pretty foundational for how LTE operates.
The court didn’t just find Google guilty of infringement. The judge also criticized the company for what it described as an “insincere attitude” throughout the proceedings. As a result, the ruling bars Google from selling, displaying, transferring, or importing Pixel 7 series devices in Japan — a market where the Pixel lineup has seen major growth over the last couple of years.
Pantech Isn’t Done Yet
The lawsuit doesn’t stop with the Pixel 7. Pantech, with the help of patent licensing firm IdeaHub, is now reportedly targeting Google’s newer Pixel 9 and even upcoming Pixel 10 series. While it’s still unclear whether those efforts will succeed, another sales ban — especially on current-generation devices — would hit much harder.
Japan, is no doubt one of Google’s most successful markets when it comes to the Pixel phones, especially a after the Pixel 7 and the Pixel 7a made a hit on the Japanese market. If this ban extends to newer models, it could go the long way to slow down Google’s potential growth in this market.
Who Is Pantech, and Why Now?
If the name Pantech rings a bell, it’s probably because they were once a prominent phone brand in Korea. But they haven’t launched a new smartphone in years, having paused their hardware business. These days, they’re more involved in patent licensing and enforcement, with firms like IdeaHub helping to push legal action.
This type of strategy — monetizing old but valuable patents — isn’t unusual in the tech world. But it does raise questions about how international IP law affects global product availability, especially when it comes to widespread technologies like LTE.
What’s Next for Google?
At the moment, the Pixel 7 ban likely won’t hurt Google too much — that phone’s lifecycle is winding down, and many buyers have already moved on to newer models. But if Google pulls the Pixel 8 or 9 from Japanese shelves, that’s a different story. Japan is one of Google’s fastest-growing Pixel markets, and any disruption there could have a lasting impact.
For now, Google hasn’t commented publicly on the ruling, but it’s safe to assume they’re looking at their legal options — and fast.
We’ll likely hear more in the coming weeks, especially with the Pixel 10 series expected later this year. Stay tuned.
