Section 3 of Indian patent act, 1970 tells you about "What are not inventions". In point number "k", you can see
(k) a mathematical or business method or a computer programme per se or algorithms;
is not eligible to get a patent in India.
What does the line "Computer Programme per se or algorithms" means?
I think to get the best out of this line is to research and gather more information about it on the internet. I have gone through USPTO website and found "Patent Subject matter Eligibility". USPTO provides a hard language to explain the patentability of inventions. But, I had found something interesting in the points.
In the non limiting example of claims point number 4 (you can check it by clicking here). I have found the word "computer program per se" with case Gottschalk_v._Benson.
Now, My initial research gives me a case citation. After that, I had researched it on Internet Repository and found something interested matches with Indian Patent Law, 1970 (Section 3(k))
In Gottaschalk V Benson,
"Supreme Court of U.S ruled that a process claimed directed to numerical algorithms are not patentable."
After more research, I found something useful
According to Manual of Patent Office Practice and Procedure, 2011
Indian Patent Office gives broad explanation to "Computer program per se", which is
If the claimed subject matter in a patent application is only a computer programme, it is considered as a computer programme per se and hence not patentable. Claims directed at computer programme products‘ are computer programmes per se stored in a computer readable medium and as such are not allowable. Even if the claims, inter alia, contain a subject matter which is not a computer programme, it is examined whether such subject matter is sufficiently disclosed in the specification and forms an essential part of the invention.
Initial Research Conclusion
If you want to patent a software in India then it must not "Computer program per se" or just a computer program. "Computer software with technical application to industry or used with Hardware" is patentable.
