The brand new HTC Vivid smartphone boasts a dual-core processor, a 4.5 inch super LCD display and 4G LTE. And according to a high-profile porn producer, it’s a trademark violation.

Vivid Entertainment Group, the U.S. porn studio that brought you the Kim Kardashian sex tape, has sent a cease a desist letter to HTC. It claims that their new phone infringes upon their trademark. According to TMZ, Vivid thinks that customers could get confused and “think Vivid is behind the phone.”

Apparently, the letter threatens a lawsuit if HTC doesn’t change the name of their device by Monday, November 21st.

This isn’t the first time that HTC has come under fire for trademark infringement. Earlier this year, their Facebook-enabled phone the HTC ChaCha drew the ire of ChaCha Inc, the company that provides real-time answers to queries via text and internet search.

TheVerge has received a response from HTC regarding the issue:

We are reviewing the complaint and don’t expect to have any further comment until it is resolved.

So there. The complaint is real, and is something that HTC is probably going to have to take seriously. I mean, who wants a giant porn producer riding their ass?
