Company patents
Molex, LLC
Molex, LLC's patent strategy reveals a surprising shift away from its core strength in Electrical Connectors, which still constitutes 52.3% of its portfolio but has seen a consistent decline in patenting activity, including a -23.9% YoY drop in 2026 so far. While most categories show declining trends, the company did experience a significant surge in Optical Elements & Systems patents in 2025 with a +58.3% YoY growth, indicating a potential, albeit volatile, emerging focus in this area.
