Listed midway down the page is a "Serial Number" field. In the case of this application, it is 741429. At the top of the page is a "home" button. Click the home button and then select "Advanced search" underneath "PATFT: Issued Patents". In the "query" box, enter "apn/" and the serial number, i.e., "apn/741429". Click search. Five titles appear, none of which is anything close to this patent, so it looks to not have been granted.

If you really want to be sure, go to the main homepage: "www.uspto.gov", and pick "2 search" under "Patents". Then pick "Patent application information retreiveal (PAIR)". Then pick "Public PAIR". Answer the capacha, and then put the series and serial numbers into the lookup box (i.e. 11741429), leaving the radio button set for "application number". Click search. If it had issued, on the next screen under "Patent number" and "Issue Date of Patent" you would find both the number and issue date. In this case, no values, so not issued. If you want to know more you can pick the "Image file wrapper" tab and look through the documents that make up the patent application. This one is still being prosecuted, but has not issued as a patent.
