Patents can be searched for in various ways. The most reliable is the patent number, but if the patent number is not available, one can search by other known information including the name of the inventor, the current assignee, or the description of the invention. In this case, we are going to search by the name of the inventor. Prince R. Nelson. In case you don't recognize the name, he was a pretty famous musician in the 20th and 21st centuries. Go to Google Patents and search. If you happen to know the exact name the patent is registered under, using quotation marks will make finding the patent easier. If not, leave off the quotation marks.
Since I used the quotation marks, we really only get one result. This shows how helpful using quotation marks can be if you know the name of the inventor or assignee can be.
Note that if I did not use the quotations marks, the results look different, but not unmanageable. Notice that the first result in this case, is still the one we want.
