Philips and Fitbit have settled a long-running patent dispute relating to wearable health technology. The case highlights the importance of patent validity and the careful drafting of software-related inventions in the digital health sector.
Philips and Fitbit Settle Long-Running Dispute
Philips and Fitbit, now owned by Google, have settled a patent dispute concerning fitness-tracking technology, bringing litigation that began in 2019 to a close.
The parties filed a joint stipulation in the US District Court for the District of Massachusetts confirming that they had resolved the dispute and requesting dismissal of the case with prejudice, meaning the claims cannot be brought again. The commercial terms of the settlement have not been publicly disclosed.
Although the litigation has now formally concluded, the case highlights several issues relevant to companies developing digital health technologies and connected devices, particularly in relation to patent validity and software-related inventions.
Background to the Litigation
The dispute began in 2019 when Philips alleged that Fitbit’s wearable fitness trackers infringed several patents relating to health-monitoring and activity-tracking technology. According to Philips, Fitbit devices incorporated patented systems used to monitor physical activity and analyse health data generated by wearable sensors.
Fitbit denied infringement and challenged the validity of the patents. During the litigation, Fitbit was acquired by Google, meaning the dispute continued with Google’s backing. The case also formed part of a broader set of disputes; Philips had previously filed a complaint before the US International Trade Commission (ITC) seeking to block imports of certain wearable devices, although that action was ultimately unsuccessful.
Patent Validity Narrowed the Dispute
Over the course of the proceedings, the number of patents in dispute narrowed significantly. Several of the patents asserted by Philips were invalidated either by the court or through administrative proceedings before the US Patent and Trademark Office (USPTO).
The final remaining patent was ultimately ruled invalid by the federal court. The court concluded that the patent claims were directed primarily to the collection, analysis, and presentation of information generated by wearable devices, which it considered an abstract concept. Following these rulings, the parties reached a settlement and jointly requested that the court dismiss the case.
Patent Eligibility and Software-Related Inventions
The invalidity ruling centred on patent eligibility under 35 U.S.C. § 101, which limits patents for abstract ideas, natural phenomena, and laws of nature. Under the framework established by the US Supreme Court in Alice Corp v CLS Bank (2014), courts consider whether a patent claims an abstract idea and, if so, whether the claims include an additional "inventive concept" sufficient to transform that idea into a patent-eligible application.
In this case, the court determined that the patent claims largely described the processing and presentation of health-related data. Because the claims did not include a sufficiently inventive technological implementation beyond this concept, the patent was held invalid.
A Reminder for Digital Health Innovators
The settlement between Philips and Fitbit brings an end to a dispute that ran alongside rapid growth in the wearable technology sector. For companies operating in digital health and connected devices, the case illustrates:
- The Power of Validity Challenges: Enforcement often hinges on whether a patent can survive rigorous scrutiny at the USPTO or in court.
- The "Alice" Hurdle: Software-driven technologies must demonstrate a specific technical improvement rather than just a digital method for data collection.
- Strategic Licensing: As the market expands, robust and defensible patent portfolios remain key competitive assets, but they must be drafted to withstand increasingly rigorous eligibility standards.
