Patent No. EP3728095 (titled "Method And Elevator Controller For Controlling An Elevator Group Having A Plurality Of Elevators On The Basis Of Destination Calls") was filed by Inventio on Nov 27, 2018. The application was issued on Mar 16, 2022.
Method for controlling an elevator group with multiple elevators based on destination calls from users, where the service elevator is assigned after a delay period rather than immediately upon receiving the call. The delay period allows consideration of subsequent destination calls and optimizes elevator utilization and user waiting times. The delay period is longer than the calculation time required for assigning the service elevator, and can be dynamically adjusted based on passenger traffic and elevator operation.

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.
