Ask Patents is a question and answer site for people interested in improving and participating in the patent system. It's 100% free, no registration required.

Recently we published one application in Google Play. This is our first experience. But my manager asked me to check whether our application name has already been taken by someone/whether the name has a patent. This seems wired to me.

So, I did a search and come up with one information, like Until your application get famous and earning lots of money, ignore about patent. No body will attack you.

But I don't know exactly which apps names are under patent. How can I find the list of all patent apps? Or Google will send us some information if the name has already been patent etc.

What's your opinion/experiences ?

Thanks for your interest in patent information, but the AskPatents/StackExchange style is Q and A, not opinion/discussion. To search for patents, try google.com/patents –  Ron J. May 19 '14 at 13:02

It sounds like you are asking about a trademark (e.g. name of a product). You can do a US trademark search at www.uspto.gov

Trademarks aren't like patents, there isn't a single national registration. Someone could obtain a federal trademark (search at tess2.uspto.gov), but there are also state registrations, as well as unregistered trademarks.

If you are going to be spending real money on the mark, it's worthwhile to engage an attorney to do a full analysis.

You'll need to perform a separate search for each territory / jurisdiction you [plan to] distribute your App in, the WIPO offer this list of offices / websites. You should also identify if any of the markets you are distributing your app in consider software patentable, then if applicable perform a search to see if your App's algorithm (concept) is already protected in that market. If it is you'll need to decide what to do: withdraw your app, seek a license, seek to buy the patent....... As your App is already public you'll be unlikely to obtain a patent for any method it utilises, even if a new / novel.
