Thanks a lot for taking the time to respond. This is how I interpreted the situation as well.

What complicates matters is that the product name is a registered trademark, and the holding company also has patented the tool. I raised these concerns with my management but they still want to proceed, so I saved well the written confirmation. We'll be using the tool internally, no plans to sell it.

OK, that is not a problem in EU where software are 99,99% impossible to register.

Anyways, a patent applies to an invention. A nag screen would not arguably be the object of the patents for that tool since it wouldn't be their own distinct invention. You can only patent novelties.

You've done well.
