Supersleuthing IDD,
This is fresh out of the oven - published 23 December 2021 - priority 18 June 2020 - too early to access the drawings and not yet available on Espacenet!
BRN's CSNN application (my favourite) priority 1 November 2018 - published 7 May 2020.
WO2020092691A1AN IMPROVED SPIKING NEURAL NETWORK
The dates are highly significant:
The Tata patent was first filed in India just over 5 weeks after the BrainChip patent application was published and about 7 months afer a collaboration between Brainchip and Tata was announced.

BRAINCHIP AND TATA CONSULTANCY SERVICES (TCS) JOINTLY PRESENT A DEMONSTRATION FEATURING ITS AKIDA NEUROMORPHIC TECHNOLOGY PLATFORM AT NEURIPS 2019
The paper titled “Human Gesture Recognition using Spiking Input on Akida Neuromorphic Platform” co-authored by Sounak Dey, Arijit Mukherjee from TCS Research at Tata Consultancy Services (TCS) and Gilles Bézard, Douglas McLelland from BrainChip will be presented. The demonstration will involve capturing a few hand gestures and hand positions from the audience using a Dynamic Vision Sensor camera and performing live learning and classification using the Akida neuromorphic platform. This will showcase the fast and lightweight unsupervised live learning capability of the spiking neural network (SNN) and the Akida neuromorphic chip, which takes much less data than a traditional deep neural network (DNN) counterpart, consuming much less power during training.
One year after we filed our CNN2SNN patent application, we announced a joint presentation co-authored with the Tata inventors Sounak Dey, Arijit Mukherjee .
The tata patent application takes CSNN as a fait accompli. The desrcription in the Tata specification is only about 60 paragraphs, whereas the Akida description is over 160 paragraphs. Their invention is about an application of CSNN, not about the invention of CSNN - even Nelson with his telescope to his blind eye could not miss these dots.
Can't wait till the Tata drawings are available.
