Executive Summary
The patent dispute between Taction Technology and Apple illustrates how an invention can create value beyond the application for which it was originally developed. Taction's technology began as a way to reproduce the physical sensation of deep bass in headphones, but its underlying capability—creating precisely controlled tactile sensations—became relevant to haptic feedback in smartphones and wearables. In September 2026, a jury found that Apple infringed two Taction patents and awarded approximately $5.7 billion in damages; Apple has said it will appeal. Whatever the litigation's ultimate outcome, the case presents an important management lesson: A patent portfolio should be evaluated not only by the products its inventions were created for, but by the underlying capabilities those inventions might bring to adjacent and potentially non-adjacent markets.

How Far Can a Patent Travel?
Taction Technology developed its tactile transducer technology to solve a problem in audio: headphones could reproduce the sound of deep bass, but not the physical sensation experienced at a live performance. Taction's approach combined conventional audio with controlled vibration that could be perceived through touch. Its Kannon headphones demonstrated the technology in music, gaming, and other immersive applications. But describing the invention simply as headphone technology obscures the more important capability: Taction had developed a way to create precisely controlled tactile sensations.
That distinction becomes important when the technology is considered outside its original application. Apple's Taptic Engine uses controlled tactile feedback in iPhones and Apple Watches, not principally to reproduce sound, but as part of the interface between a person and a device. Software actions can produce physical responses that a user feels as taps, clicks, notifications, and other forms of feedback. Taction sued Apple in 2021, alleging that certain Apple devices infringed two of its patents. After an earlier judgment of noninfringement was vacated by the Federal Circuit, a jury in September 2026 found infringement and awarded Taction approximately $5.7 billion. Apple has said it will appeal. Whatever the ultimate outcome of the litigation, the underlying technology had traveled from feeling sound in headphones to feeling information and interaction through a digital device.
Taction illustrates what I think of as an adjacent-market opportunity. The distance from headphones to smartphone haptics is meaningful, but the underlying capability remains recognizable. That suggests a useful way to examine an existing patent portfolio. Begin with the product or market that produced an invention, but don't stop there. Translate the invention into the capability it provides and then move outward: from its current application, to adjacent applications, to adjacent markets, and eventually to non-adjacent markets where the same capability might solve an entirely different problem. A patent described as "headphone technology" produces one set of possibilities. Technology described as "creating precisely controlled tactile sensations" produces another. The way an organization defines an invention can determine where it looks for its value.
Finding those additional applications, however, is only the beginning. Patent analytics, technical research, semantic search, and increasingly capable AI tools can identify relationships among technologies and suggest markets where a capability might apply. They cannot by themselves determine whether a technically plausible application represents an attractive business opportunity. That requires understanding the problem being solved, who has it, what solving it is worth, what alternatives exist, and which opportunities justify further investment. The strategic question is therefore not simply who else could use a company's patents, but what capabilities are buried inside its existing intellectual property that could solve valuable problems in markets the company has never considered.
