Company patents
ESSITY HYGIENE AND HEALTH AKTIEBOLAG
Essity Hygiene and Health Aktiebolag, despite its name suggesting a focus on hygiene, surprisingly dedicates a significant 45.1% of its patent portfolio to 'Implants & Prosthetics', a medical device category, which saw a substantial 40.0% growth in 2025. Concurrently, the company is showing an emerging focus on 'Sterilization & Biocompatible Materials', with a 100.0% year-over-year growth in both 2025 and so far in 2026, indicating a strategic expansion within the medical device sector beyond traditional hygiene products.

Implantable devices designed to manage or redirect bodily fluids, including stents for ducts, and systems for draining or accumulating fluids within internal cavities.
Development and application of textile materials with engineered properties such as waterproofing, thermal regulation, anti-cling, structural coloration, or enhanced filtration capabilities for specific performance needs.
Apparatus and methods for automatically winding or unwinding continuous materials such as webs, cables, conduits, or yarns onto or from spools, reels, or bobbins, including aspects like layering, coreless winding, and material supply.
Systems that perform operations like cutting, folding, binding, or applying liquids to sheets or webs, often integrated within larger production lines such as printing or image forming apparatuses.
Containers or packaging components featuring active mechanisms for controlled release, preparation, or delivery of their contents, such as liquids, bulk materials, volatile compounds, or single-serve portions.
Systems and methods for uniquely identifying, tracking, and managing physical items using scannable codes (barcodes, QR codes) or wireless tags (RFID, IoT devices) to link physical objects to digital information, inventory, or services.
Systems and methods for precisely measuring, monitoring, and regulating the longitudinal tension in continuous webs of material during roll-to-roll processes to prevent defects, reduce waste, and ensure consistent product quality.
Devices providing mechanical support, alignment, traction, or targeted compression to specific body parts, often focusing on joints, spine, or limbs, for therapeutic or corrective purposes.
Apparatus designed to deliver localized massage, percussive action, vibration, or combined thermal therapy to muscles and soft tissues for pain relief, circulation improvement, or muscle recovery.
Multi-layer polymer films engineered to provide superior barrier properties against gases (e.g., oxygen), moisture, or aromas, often incorporating heat-sealing or resealing mechanisms for food and product preservation.
Devices that use motors, actuators, and control systems to provide active assistance, resistance, or repetitive motion for physical therapy, limb rehabilitation, or circulation enhancement.
Multi-layered materials incorporating fiber layers (e.g., carbon, non-carbon, fabric, mesh) within a polymer or ceramic matrix to achieve enhanced mechanical properties such as strength, stiffness, impact resistance, or tailored hardness for demanding structural applications.
Mechanisms and control systems for reliably feeding, conveying, and separating print media, including managing media roll changes, adjusting airflow, and adapting to different media characteristics.
Methods and apparatus for disinfecting or sterilizing medical devices, waste, or environments, often employing radiation, chemical agents, or thermal processes, and including monitoring systems.
