We are looking to create an app that contains someones last name in the title, as well as some data created by him.
The data is public for anyone to use in the form of spreadsheets, the goal of the app is simply to make it easier to use. The reason the last name is in the title is because the data is named after him.
We're wondering if we could be sued for this? They have their own app, but we feel it's missing a lot of features. They are on another continent, though I doubt that matters.
I have searched copyright and trademark databases and they come back with no results, but again not sure if that matters.
