Trade name Vs. Corporate name

If you are a prior user in class 9 goods certainly your right cannot be defeated.  Since you are in the field of the class 9 goods and if you are able to prove user for many years (as you have carried business in the trade name sonata for batteries for many years) you can very well maintain you application in class 9.

As regards the suit filed by Titan, I can say that you have to defend that the goods in class 14 and 9 are different and you are a prior user in class 9.  Though Titan has a registered trademark Sonata, If you establish your user rights over the name sonata then you can protect your right. 

in this case Titan says that  they have registered Trade mark under class 14 in that include watch, clock & "Parts Their of" and  batteries are the integral parts of watches. recently ( Jan 2009)Titan has also applied for Batteries of all kind & Watch Button cell under class 9. Point is that  "is the button cell intergal part of watches?" we have also applied for Trade mark "Sonata Gold" trade mark for batteries in July 2007. presently Titan is not manufacturing or trading any kind of watch Button cell in the Name of "Sonata" they are selling their batteries in the name of Titan.

How long you are using sonata as tradename for batteries?  If you are a prior user for the name sonata then you can sustain your right.

we are using our company name from july 2007 for Button cell and Titan is not using sonata for batteries.

please see the atteched file

but titan says that sonata is registered trade mark under class 14. titan has registration for Watch, Clock & Parts theirof. and button cell is the integral part of  Watches.further titan is not using sonata brand for button cell nor have registration
