You are welcome. No problem. It is one of the things I like about being here. People helping people to better understand so then we can make the changes that need to be made.

Yes, the USPTO website is very outdated.

Go here and type in the patent number, 6,506,148.

It is easier to use www.pat2pdf.org to get the .pdf file.

It is why I posted a detailed response. I have seen several posts about patents lately, and I want to make it easy for people to find what they are looking for.

I am not sure what number you searched for. I found this one. I did not watch the whole video, so I am not sure if more than one patents are mentioned.

The Patent Number is 6,506,148.

The Application Number is 09/872,528.

The Publication Number is 20020188164.

If a patent is withdrawn, then it may not show up.

If a patent is filed, but does not issue then it will never have a Patent Number. Instead, you have to search for the Publication Number or the Application Number, assuming it was published.

Excellent analysis. Simple solution: be aware and test the hypotheses yourself. Knowledge is power
