Company patents

Flex Ltd.

Flex Ltd.'s patent strategy shows a surprising shift away from its core semiconductor and manufacturing categories, with 'Printed Circuits & Electronic Assemblies' declining by 66.7% in 2025 and 'Plastics Shaping & Molding' by 100.0% in 2025. While most categories have seen significant declines, there's a notable resurgence in 'Power Conversion (DC/AC, DC/DC)' with 3 patents so far in 2026 after a 100.0% decline in 2025, suggesting a potential re-emphasis on electrical power technologies.
