We had a hunch that this between wouldn’t just fade away into the sunset, and sure enough, HP is on the receiving end of the latest scuffle. Most recently, Acer has filed patent counterclaims in the US District Court for the Western District of Wisconsin and with the US International Trade Commission, alleging that HP “infringed on patents related to personal computers, servers and peripheral devices.” Unfortunately, that’s about the extent of it, but Acer did go on to state that it would “take all necessary steps to protect and enforce its patented technologies.” If the gloves weren’t already off, we’d say they are now.
