Patent No. EP3448791 (titled "Elevator Entry Control System And Method") was filed by Kone on Apr 29, 2016. The application was issued on Jul 31, 2024.
Elevator control system that automatically determines the destination floor based on user identity and object presence. The system checks for an object identifier, such as a Bluetooth beacon or RFID tag, and generates entry control information accordingly. If an object identifier is detected, the system sets the destination floor to the object's designated location, otherwise it defaults to the user's home floor.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
