Due diligence time guys. If you click on the link on "patent" in this sentence:
"The project was conceived based on a patent developed and owned by the client."
...from relax's 7.57am post, you will find this work was done against a Tata patent, not an externally-acquired solution.
I think we need clarification whether this specific release by Tata is based on their own technology, or on CSP.
