The case that rescued software patents in India
Delhi High Court · 2019 · W.P.(C) 7/2014, decided 12 December 2019; 2019 SCC OnLine Del 11867
What happened
An applicant whose computer-implemented invention had been refused under section 3(k) challenged the refusal.
What the fight was about
Whether every invention involving a computer programme is excluded, or whether the words per se leave room for inventions built on software.
What the court decided
The words per se were added deliberately so that genuine inventions merely based on computer programmes are not refused; the bar applies to computer programmes as such, not to inventions developed on their basis. The test is whether the invention demonstrates a technical effect or technical contribution. In the digital age, refusing all software-linked inventions would be retrograde. The matter was remanded for fresh consideration.
Why an inventor should care
This is the decision behind the phrase technical effect that you will hear in every Indian software patent conversation.
What a patent professional should take from it
It is the foundation, but not the end point. The line has developed since - later decisions accept technical effect on a general-purpose computer, and the revised CRI Guidelines notified on 29 July 2025 set out a step-wise methodology with worked examples.
Software is not excluded. Software claimed as nothing but software is.

The case that put technical effect back at the centre
Software claimed as software
You cannot patent a computer programme per se. You can, on current Indian authority, patent an invention that happens to be implemented in software if it delivers a …
Not sure whether this applies to your invention?
The honest answer usually needs someone to look at your actual disclosure, your timeline and the prior art. That is a conversation, not an article.
