Company patents
Aetna Inc.
Aetna Inc. shows a surprising patent strategy, with a significant portion of its portfolio (28.0%) in Machine Learning & AI, despite a sharp decline in patenting activity in this area, with an 80.0% YoY drop in 2024 and a 50.0% drop in 2025. While Healthcare Informatics remains its largest category (34.0%), the company's focus on core medical device innovation appears to be shifting, as evidenced by a 60.0% decline in 2025, although it has seen a 50.0% increase so far in 2026.
