HTC has been struggling to compete in the smartphone market for quite some time and it seems like thing aren’t getting any better. The company has halted all sales in the UK due to an ongoing patent dispute.

Way back in 2012, a court found HTC had infringed upon a patent help by R&D company Ipcom which covered a wireless technology developed for car phones. The Taiwanese company was advised to implement a workaround, something it subsequently implemented, but Ipcom now claims HTC’s no longer complying with the original court order.

Speaking to the BBC, a spokeswoman said the that “as a leading innovator, HTC takes intellectual property issues very seriously. We are proactively investigating an infringement claim by a third party with respect to a single handset model.”
