Apple is once again at the center of a legal dispute – this time over alleged data theft related to the Apple Watch. The company accuses a former engineer of passing on highly confidential information to the Chinese smartphone manufacturer Oppo. According to a court filing, this employee even gave a presentation about Apple's sensor technology to hundreds of colleagues after joining Oppo. The case demonstrates how fiercely companies fight for technological secrets and competitive advantages.
Apple has filed a lawsuit accusing Chinese manufacturer Oppo and former Apple employee Chen Shi of stealing and sharing trade secrets. Shi previously worked on the development of the Apple Watch and, shortly before his departure, allegedly copied sensitive files and later presented them to Oppo. The presentation allegedly covered Apple's methods for researching and developing sensor hardware. The allegations are serious because they concern a core area of Apple technology—the sensors that record, among other things, heart rate, movement, and health data (via MacRumors ).
Apple's allegations
According to Apple, Chen Shi downloaded 63 files from a protected internal Box folder and copied them to a USB drive prior to his departure. These files allegedly contained sensitive technical details about sensors, hardware designs, and future product plans. Apple also claims Shi was specifically looking for information on how to conceal data theft.
After Shi joined Oppo, Apple reported that he gave a presentation titled "Apple's Philosophy and Methodology in Sensor Hardware Research and Development." Internally, the event was promoted with the slogan "Are you curious about how Apple's sensors are developed?" According to Apple, Shi presented slides taken directly from Apple's documentation and answered questions on specific aspects of sensor technology.
Apple also claims that Oppo encouraged Shi to share confidential information. Internal Oppo communications explicitly advertise Shi's talk as a presentation on "Apple sensors." The company also accuses Oppo of not fully providing the documents Apple requested. These documents are intended to shed light on the extent to which Apple information may have ended up at Oppo.
Oppo's reaction
Oppo strongly denies the allegations. The company states that it conducted a comprehensive investigation and found no evidence of the use or possession of Apple's trade secrets. The presentation presented by Shi merely covered general technical principles that were neither confidential nor specific to Apple.
Oppo also emphasizes that it has already searched for terms such as "trade secrets" or "confidential information" of Apple without finding any such data. The company therefore considers itself in the right and considers Apple's request for a preliminary injunction to be unfounded.
The current status of the procedure
The court ordered Oppo to submit the documents requested by Apple by October 31 at the latest. If the volume of documents is too large, Oppo must begin submitting them as early as October 28. Apple also demands that Shi not disclose any further information and that Oppo not develop products based on Apple technology.
Shi himself has agreed to give a deposition, but has requested an extension. Due to a recently diagnosed illness, which, according to his lawyer, could be exacerbated by stress and a lengthy trial, Shi has therefore asked the court to issue a protective order to restrict or suspend his testimony.
Apple, in turn, is demanding damages, punitive damages, and legal fees. The company is also demanding that all Oppo employees who may have had access to the copied data be isolated and kept away from projects developing competing technologies.
The significance for Apple
The case is particularly significant for Apple. The Apple Watch is considered one of the company's most important products, representing innovation, healthcare technology, and precise sensor technology. The sensor hardware is among the most tightly protected areas of Apple's research. If Oppo did indeed profit from internal findings, this could jeopardize Apple's technological leadership in the wearables sector.
Beyond the specific case, the dispute also demonstrates how risky employee transfers between large technology companies can be. In an industry where research and development spend billions over years, individual data thefts can have major financial and strategic consequences.
Between law and reputation: What really matters to Apple
The conflict between Apple and Oppo illustrates how sensitive and valuable technological innovations have become. Apple is fighting not only for legal redress but also for the protection of its research. Oppo, in turn, is trying to defend itself against the accusation of having profited from Apple's know-how.
Whether the courts will uphold Apple's allegations remains to be seen. However, the case demonstrates that intellectual property plays a central role in the global competition among tech companies. Apple is defending not only its data but also its reputation as a company that consistently protects research and security. (Image: Shutterstock / frantic00)
