Why do my pictures that I took get rejected stating "Intellectual Property Rights"?

When you’re in National parks and especially on native tribal lands, you need to be familiar with their commercial use policies. Most places allow you to take photos for personal use. But selling the photos on Stock could be restricted. Or they may require you to pay additional fees for permission to take commercial photos. Check their websites.

Light installations on buildings, tunnels & bridges are frequently protected by private entity IP.

Hope that helps.

Thank you, I really appreciate your help and for taking the time to respond.

We need to see a couple of the rejected images to be of help.
