I have a question. As we know, US trademarks are in different classes of goods and services.
Company A owns a trademark on its name, but only for a particular class of machine. It has no trademark that covers the internet. It has several trademarks on its name but all in the same class of machine item.
Company B wants to sell a supply item for these machines. Would it be a trademark infringement or not to use that name in keywords of the website?
Why or why not?
Wanted to get feedback from others.
