Company patents

ZOLL Circulation, Inc.

ZOLL Circulation, Inc. demonstrates a patent strategy heavily focused on medical devices, with Implants & Prosthetics (48.4% of portfolio) and Physical Therapy Apparatus (33.9%) as core areas, despite a significant decline in patenting activity across most categories in 2025 and so far in 2026. While patenting in Healthcare Informatics saw a 100% YoY growth in 2024, indicating a brief emerging focus, this was followed by a 100% decline in 2025, suggesting a shifting priority away from this area.
