Digital Health & Medical Devices

Technology transforming healthcare delivery

Having examined cybersecurity and the escalating arms race between digital threats and defensive innovation, this chapter turns to digital health, a domain where data security considerations increasingly intersect with patient monitoring and clinical decision support.

Digital health bridges the worlds of medicine and computing, encompassing a broad range of technologies designed to capture, analyze, and act upon health-related data. This chapter traces the evolution of digital health patenting — from early patient monitoring devices through the electronic health records revolution to the current era of AI-driven clinical decision support and robotic surgery.

Growth Trajectory

Digital Health Patenting Strategies

The leading digital health patent holders pursue different strategies. Some firms concentrate on patient monitoring hardware, while others emphasize health informatics and clinical decision support. A comparison of subfield portfolios across major holders reveals where each organization concentrates its inventive effort and identifies areas of emerging competition.

Digital Health as a Cross-Domain Technology

A defining characteristic of digital health is its diffusion across multiple technology domains. By tracking how frequently digital health patents also carry CPC codes from other technology areas, it is possible to measure the spread of healthcare technology into computing, chemistry, and other sectors — and conversely, the adoption of external technologies within healthcare.

Figure 9

Digital Health Patents: 14.47% Co-Occurrence With Electricity (Section H) in 2024

Digital health patents co-classified with other CPC sections, measuring cross-domain integration.

Percentage of digital health patents that also carry CPC codes from each non-primary section. Rising lines indicate increasing integration between digital health and that technology sector. The most notable pattern is the growing co-occurrence with Electricity (Section H, encompassing electronic circuits and communication) and Performing Operations (Section B, encompassing surgical instruments and transporting).
The cross-domain diffusion of digital health patents is consistent with its characterization as an integrative technology that draws on computing, materials science, and clinical methodologies to deliver healthcare innovations.

The Complexity of Digital Health Innovation

Since the mid-1990s, digital health patents have involved more inventors per patent than non-digital-health patents, and this gap has widened over time as the complexity of integrating clinical, engineering, and regulatory requirements has grown. Corporate assignees dominate, reflecting the multidisciplinary nature of modern healthcare technology.

Before the mid-1990s, digital health team sizes were comparable to or slightly smaller than non-digital-health patents. Since then, digital health teams have grown larger, reflecting the increasing need for expertise spanning biomedical engineering, software development, clinical science, and regulatory affairs.
Since the mid-1990s, digital health patents have involved larger teams than non-digital-health patents, a pattern that reflects the growing multidisciplinary demands of integrating clinical knowledge, engineering expertise, and regulatory compliance.

Having documented the growth of digital health in the patent system, the analysis reveals a domain undergoing rapid transformation. The convergence of patient monitoring hardware with AI-driven clinical decision support, the expansion of telemedicine accelerated during the COVID-19 pandemic, and the growth of surgical robotics collectively point toward a future in which the boundaries between medical devices and computing platforms become increasingly indistinct. The organizational strategies documented here are explored further in Assignee Composition, while the broader relationship between digital health and artificial intelligence is examined in the chapter on Artificial Intelligence.
