I actually couldn't! I looked as best as I could. Their search engine is horrible. Maybe you could offer a link rather than make uncharitable assumptions.

edit:

>> "No, I am not your servant."

Asking you to show your work is not asking you to be a servant.

>> "What work? I told you how to look up trademarks and patents. I can do it again: If you want to look up trademarks and patents you can use the search function on the uspto website."

As I said: I did. Nothing came up that had anything to do with these filters.

Feel free to keep arguing with phantoms here. I'm moving on since you clearly aren't paying attention.
