Some years ago i used a page generator to make doorway websites.
And i used another tool ti find popular keyword phrases.
In short i used the term " pottery barn" in the heading at some of those pages and this have a trademark.
Read about it here:

When i knew about this case, removed the sites with that term "pottery barn"
Hope to get some good advise about this case.
