Company patents
ENI S.P.A.
ENI S.P.A. shows a surprising focus on Organic Electronics (OLED), which constitutes 16.2% of its portfolio, despite a significant decline of -85.7% so far in 2026. While traditionally strong areas like Drilling & Mining (13.7% of portfolio) are seeing a consistent decline, the company's patenting activity across most categories has sharply decreased in 2026, with many categories showing a -100.0% YoY decline, indicating a potential shift in overall patent strategy or a significant lag in current year filings.
