Just finished my graduation and excited to start a business! I’ve created an educational software using ideas from some books. I just used the books as inspiration and built my own software. Do I need permission from the book authors to use my software?

You likely don’t need permission from the book authors. Using ideas from books as inspiration for your own software is generally considered fair use under Indian copyright law. However, you should avoid directly copying any text or code from the books to avoid copyright infringement.
