Intellectual Property India Publishes Patent Application for 'Pulmonary Embolism Classification System' Filed by Lovely Professional University

MUMBAI, India, Jan. 7 -- Intellectual Property India has published a patent application (202511102352 A) filed by Lovely Professional University, Phagwara, Punjab, on Oct. 24, 2025, for 'pulmonary embolism classification system.'

Inventor(s) include Mohit Prakram; Dr. Sorabh Lakhanpal; Dr. Rajesh Verma; and Rishi Chopra.

The application for the patent was published on Dec. 12, under issue no. 50/2025.

According to the abstract released by the Intellectual Property India: "A pulmonary embolism classification system comprising a preprocessing module 101 with an autoencoder-based dimensionality reduction architecture that compresses CT pulmonary angiography images while preserving critical features, a data augmentation module 102 enhances training data diversity using rotations, flips, and intensity transformations, a discrete wavelet transform (DWT) module 103 extracts multi-level spatial and frequency-domain features, while the Sobel filtering module 104 emphasizes vascular boundaries and suppresses noise, an ensemble classification module integrates ResNet50, DenseNet121, and Swin Transformer networks to leverage their complementary strengths, a decision fusion module employs a soft-voting protocol with confidence-based calibration to combine ensemble outputs and generate a robust final classification."
