Patent No. EP3299327 (titled "Prognostic Analysis Of Elevator Performance Using Sensors And Internet Of Things") was filed by Otis Elevator on Sep 22, 2017. The application was issued on Jul 30, 2025.
A system for predictive maintenance of elevators using IoT sensors and machine learning. The system captures elevator performance data through sensors and analyzes it using neural networks to identify potential issues. It automatically reports identified problems and recommended resolutions to building operators, who verify the findings. The system then executes the resolutions or schedules a mechanic for on-site repair, reducing the need for multiple site visits.

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.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
