( Engadget ) - We've heard a lot of talk from Hop-on, makers of all those cheap cellphones that never seem to go anywhere, but the company may have bitten off a little more than it can chew with its latest trademark registration filings for "YahooPhone" and "YPhone." Yep, that's right -- those names bring to mind any massive consumer-oriented companies that might not be happy? Oh, right. There's been some speculation that Hop-on is actually developing a phone for Yahoo!, since it has some deals in place with AT& T and Verizon, but it's pretty unlikely the company is also in charge of branding to the point where it's registering trademarks. No, our guess is that someone's hoping that the folks up in Sunnyvale are a little too distracted by the clumsy advances of one Mr. Ballmer to keep track of a little thing like potentially infringing trademark registrations -- yeah, we don't think that's going to work out so well for you, guys.
