I want to produce a much simpler web app inspired by a more complex web app, with some additional features of my own. The original web app was inspired by a process in general knowledge.
From this page, I see that:
My own web app's
"work is considered original – and thus protected by copyright – if you use your skill, labour, judgement and effort to create it. Using another’s work is copyright infringement when ‘the work as a whole or any substantial part of it’ has been copied."
I understand that
The meaning of ‘substantial’ changes is defined on a case-by-case basis.
Given the original app's central process is inspired by general knowledge, and I am using a much simpler version or process than the original web app and adding my own features, would my own web app break copyright?
