How to represent and cite a patent using BibTeX?
Firstly, BibTeX is more or less a data structure. You can populate its fields however you want, as long as it captures the essential information. 

Now, there is an @patent{...} type which, while not standard, is supported by many styles. Check the documentation for the citation style you are using for details. As you would be using either the @misc or @patent types, you should try to populate your fields or configure your styles in a way that the compiled output from BibTeX matches the expected style of the document that you are trying to prepare. 

For example, IEEEtran's BibTeX package supports that @patent type and you can read their documentation on what fields should be populated and how. In particular, they support the number field which you should populate with 4741207 and the nationality field which you should populate with United States, instead of the Google output which put those information in the note field. The publisher field is actually ignored in the IEEEtrans style, so you don't need to do anything about it, and the url you can just drop, since given the United States patent number it is relatively easy to find it on the USPTO website. 

If your publication follows the Chicago manuals, here's how they prefer it to look. Note in particular it does not show any "publisher" or "url" information.

If you use biblatex, this TeX.SE q/a gives a pretty good sample of acceptable use. 

In short, like most questions about "how to cite blah", the answer is:


  The point of a citation is to give an unambiguous reference to previously published material. Many publishers and societies have established conventions and styles and the practical suggestion is to follow their guidance in how to style your bibliographic information. Absent that, use your own best judgment about how much information is sufficient to identify the reference.
