"In India, the software is not directly patented but it can be granted patent if it is attached with novel hardware, an invention that is unique and capable of industrial use."
So patenting a pure algo or data-structure will face legal hurdles.
This would be an interesting use case for making country specific distro ISOs/variants which don't have the usual patent issues (ala rpmfusion for things like ffmpeg etc.). However, there's no money to be recovered from such an exercise because all the legal analysis is funded by RedHat and there would be little payoff for doing this type of work. So it may not be so straightforward. And RedHat is now owned by IBM, which is synonymous with software patents. So not sure what that implies either.
