The function of Apple Watch automatic fall detection UnaliWear is once again at the center of a legal dispute in the United States. The International Trade Commission (ITC) has launched a formal investigation to determine whether this feature, also found in watches from other brands, infringes on patents registered by the Texas-based company.
Although the focus of the proceedings is on the US market, the case is not limited to the Apple Watch nor is it irrelevant for those who use these devices in Spain or the rest of Europe. The investigation affects smartwatches from Apple, Samsung, Google and Garminand any strong decision by the ITC could influence how manufacturers design and offer their safety features globally.
The ITC scrutinizes fall detection
The investigation opened by the ITC is based on the Section 337 of the United States ActThis is a legal instrument used when there is suspicion that products infringing on intellectual property rights are being imported or sold in the United States. In this case, the subject of analysis is so-called "wearable fall detection devices and their components," a category that includes current smartwatches.
According to the notice initiating the investigation, UnaliWear maintains that certain wearables with fall detection violate two patents registered in the United States: number 10.051.410 (known as patent '410') and 10.687.193 (patent '193'). These protections cover technologies related to how the device detects that the user has fallen and what actions are taken next, such as sending alerts or contact emergency services.
The ITC is not a criminal court nor does it set financial compensation, but it has the power to impose very severe trade measuresAmong these measures, the most significant is the possibility of preventing the entry of the specified devices into the country, as well as blocking their sale if they have already been imported. For a company like Apple, or for manufacturers with global product catalogs like Samsung, Google, or Garmin, a ban of this kind could completely disrupt their product strategy.
For a case of this type to succeed, US law requires that there be a domestic industry linked to the affected patentsUnaliWear claims to meet this requirement, alleging that it develops and markets fall detection technology in the United States based on the patents in dispute, something that is key for the ITC to continue the case.
From a European perspective, it may seem like a distant conflict, but any decision that limits the use of certain solutions in the United States usually impacts manufacturers' global roadmaps. If companies are forced to modify how fall detection works to comply with an ITC ruling, it is likely that These changes will eventually reach the models sold in Spain and the rest of Europe as well., often through software updates.
What is UnaliWear claiming, and who is the investigation focusing on?
The complaint that triggered the ITC was filed by UnaliWear, a Texas-based company Specializing in security solutions for vulnerable users, the company's statement doesn't just point to Apple: the wording used encompasses "electronic watches capable of detecting when a user has fallen, and their components," an umbrella term that also includes certain models from Samsung, Google, and Garmin.
The core of the conflict is the specific way in which these watches identify a potential fall and they manage the subsequent responseUnaliWear maintains that the implementation of this function across different devices It invades the area protected by its patents, at least in several of the technical aspects described in the claims of patents '410 and '193.
Regarding the requested measures, the Texas company is asking the ITC to issue a limited exclusion orderwhich would serve to block the importation into the United States of the allegedly infringing devices. Furthermore, it claims several cease and desist orders intended to prohibit the sale of watches already in the country that, in the opinion of the ITC, use technology covered by the disputed patents without the corresponding authorization.
Translated into more everyday language, UnaliWear seeks to prevent the targeted models from entering the US market and to stop those already in circulation. cannot continue to be marketed normallyThe mere possibility of these measures being implemented puts pressure on manufacturers, who could be forced to negotiate licenses, modify the design of the function, or, in the worst case, partially or totally disable it in certain regions.
In the European context, a potential veto in the United States would not automatically require the same response in the European Union, but brands often try maintain a product line that is as unified as possible to simplify production, support, and updates. Therefore, if an agreement is reached or the fall detection technology is redesigned, it wouldn't be surprising if this new approach is also applied to watches sold in Spain.
A new front after the conflicts with Masimo and AliveCor
The research into fall detection doesn't emerge in a vacuum: the Apple Watch already has a long history of this technology. a history of patent disputes related to health functionsIn recent years, Apple has faced conflicts with, among others, AliveCor and the medical technology company Masimo, centered on advanced monitoring tools.
The Massimo case was particularly high-profile. The ITC concluded that certain Apple Watch models violated regulations. patents related to blood oxygen measurementThis led to a temporary import ban on several Apple Watch models in the United States. For a time, this decision forced Apple to adjust its business strategy in one of its key markets.
Later, the company managed to lift the ban and continue selling its watches, although the legal battle with Massimo It has not been completely closedThe case made a trend clear: the health functions of wearables, once seen as mere extras, have become a highly strategic and therefore highly contested area from an intellectual property point of view.
In this new scenario, UnaliWear's complaint once again shifts the focus to another feature heavily promoted by manufacturers: the automatic fall detectionThis feature has been marketed as a safety tool designed for seniors, users with reduced mobility, or athletes who train alone, especially on high-end watches such as the most advanced Apple Watch models or Garmin adventure devices.
If the ITC were to rule that the technology used by Apple, Samsung, Google, and Garmin infringes on UnaliWear's patents, a scenario similar to that of Massimo could be repeated, with restrictions on the import and sale of certain models in the US market. Faced with such a scenario, companies would have few options: appeal, renegotiate, license the technology, or redesign the function to avoid the area protected by the disputed patents.
Timelines, potential market effects, and a European perspective
For now, the ITC's investigation is in its early stages. The agency has notified the affected companies—including Apple, Samsung, Google, and Garmin—that They have 20 days to respond from the official receipt of the documentation. This deadline is key because, if any party does not respond in time, the Commission may consider that it waives its right to defend itself at this stage.
The notice itself states that a lack of response may be interpreted as a waives the right to appear and challenge the allegationsIn that case, the administrative law judge and the ITC could accept the facts as described by UnaliWear and move towards an initial decision, which could eventually become an exclusion order or cease and desist orders against the manufacturers involved.
If the process continues, it will typically last for months. The ITC usually carries out extensive technical analyses and detailed comparisons among the patents and technologies used in the products under investigation. This includes document review, expert testimony, and often hearings in which each party presents its arguments. At the same time, it is not uncommon for the affected companies to explore private settlements or technical changes that would allow them to resolve the case before final sanctions are imposed.
For users in Spain and the rest of Europe, the impact of these types of disputes is not usually immediate, but it can be noticeable in the medium term. Wearable manufacturers tend to unify hardware and software on a global scaleThis is important both for efficiency and brand consistency. If fall detection is modified, limited, or reconfigured to comply with an ITC resolution, those adjustments will most likely be reflected in European versions of the Apple Watch and other popular smartwatches as well.
So far, neither Apple nor the other companies named have issued a detailed statement regarding this new investigation. Some specialized media outlets have attempted to gather comments, awaiting a response. An official response clarifying whether the companies will choose to litigate until the end., seek an amicable agreement or introduce technical changes in fall detection to circumvent the area that UnaliWear considers protected by its patents.
With this new case opened, the fall detection feature of the Apple Watch and other smartwatches joins the list of health functions that create tension between technological innovation and intellectual property rights. The ITC's final decision on these matters remains to be seen. UnaliWear patents and the use of fall detection It will most likely set the course for major wearable brands in their next product generations, both in the United States and in key markets for them such as Spain and the rest of Europe.
