Qualcomm has made the next move needed to enforce a German court order banning the sale of older iPhones in the country for infringing on Qualcomm patents related to power saving technology.

The chipmaker on Thursday posted $1.52 billion in security bonds, required to enforce the Dec. 20 Munich court order against Apple, which also applies to infringing iPhones sold from third-party resellers in Germany.

Following the ruling, Apple said it would pull iPhone 7 and 8 devices from its 15 retail stores in Germany, pending an appeal. 

Qualcomm and Apple are in a similar patent dispute in China. Last month a Chinese court sided with Qualcomm, banning certain iPhone models over patent infringement. Apple has not pulled its phones in that country, though, saying the issue only applied to older devices and instead pushed a software update.  

Earlier this week Apple cut its revenue guidance for the first-quarter, citing lower iPhone sales, particularly in China.
