Well, this news sounded a bit fishy.. so I decided to do a little research. First of all, for the reporter- All US patents are public, anyone can easily search from uspto.gov. I don't know much about aircrafts, but unmanned drones are not new obviously and neither is GPS. Probably there is something new in use of the technology, that is why Mr. Regmi filed the patent. You can view his patent application: http://www.google.sc/patents/U...
Now, comes the final part- whether his patent actually got approved or not. This is also no brainer to search. Go to http://portal.uspto.gov/pair/P...
There you will have to put captcha and it lets you search the application. Search it using the publication number:20120072058
On doing that, you will see the Status: "Notice of allowance mailed" and the date is 02-03-2014 (MM-DD-YYYY format). This means that his application is actually approved and the notice has been sent to his address. Now he will have to pay certain amount which depends upon the complexity and type of the patent that he has filed and probably that information is not public.
Congratulations to Mr. Regmi. Hope you will be able to claim your patent and do something good out of it.
