In the world of K-pop, HYBE is no longer just a music label, it is a tech giant. While fans focus on the music, a revolution is taking place in patent offices.
BTS, HYBE’s biggest group and the driving force behind the company’s rise into a global empire, is back. A comeback is underway, and in less than ten days the BTS wave will take over the world, starting with a live broadcast reaching more than 190 countries. This will be followed by a several months tour: 79 concerts across five continents. Tickets have sold out almost instantly. Not every fan will be able to attend.
But HYBE has a solution. While BTS members were completing their military service, the company continued to work and, most importantly, to innovate.
The lightstick: More than an accessory
Recently, a new version of the ARMY Bomb, BTS’s official lightstick, was released. New design, new colors, and new functions. Yet behind this lies a technological revolution that appears in HYBE’s latest patent filings.
Lightsticks are an essential part of the concert experience. Connected to the control system, organizers use these glowing devices to create synchronized waves of color throughout the audience. Stage and crowd become a single visual performance.
Until now, however, the show stopped at the walls of the concert venue. It is not the case anymore.
The birth of the “Virtual Stadium”
A lightstick turned on in a bedroom in Paris could change color at the exact same moment as the thousands of lightsticks glowing inside a stadium in Seoul.
This is not magic. It is a complex intellectual property architecture. Music labels no longer sell only music. They are building technological systems designed to extend the emotional experience of concerts beyond the venue.
Turning smartphones into relay stations
In a Korean patent application titled “Method and system for managing multiple external repeaters”, HYBE is legally redefining what it means to attend a concert. As an intellectual-property in-house lawyer and ARMY, I looked into the company’s recent filings to understand how intellectual property is being used to build the “Virtual Stadium” of the future.
In a Korean patent application filed in April 2024 and later extended to the United States, Japan, and China, the company proposes a new method that allows concert organizers not only to control the lightsticks inside the concert venue, but also those located elsewhere. Originally, such systems were developed to deal with the technical constraints of concert venues themselves, such as signal transmission limits.
Inside the venue, lightsticks are connected directly to the control system. At home or elsewhere, however, the lightstick can connect to a dedicated phone application to adjust colors and settings. Under HYBE’s proposed system, that phone application could become one of the external repeaters, receiving the same control signals as the devices in the stadium.
The “Streaming Spot” concept
The patent application goes even further by introducing the concept of a “streaming spot”. HYBE anticipates secondary broadcast locations such as cinemas, cafés, or other public venues where dedicated equipment could manage hundreds of fans’ devices locally. With this remote management system HYBE is positioning itself as a private network operator for its fans.
Intellectual property as a shield
By creating lightsticks and protecting the entire technological ecosystem around them, Korea is positioning itself at the forefront of innovation in the music industry. K-pop has already conquered the world and continues to shape global pop culture and musical trends. The technologies surrounding it are now following the same path. Lightsticks, once a uniquely Korean concert tradition, are beginning to appear in other music scenes.
What began as a fan accessory has become a sophisticated piece of technology, and a symbol of how Korea blends entertainment and technology to reinvent the live music experience. The country is not only exporting music, but also exporting innovation.
