HTC filed infringement claims with the U.S. International Trade Commission (ITC) against Apple on Wednesday using patents it got from Google last week.
The new filing is an amended complaint filed previously with the ITC, and now cites nine new patents previously owned by Google but transferred to HTC on Sept. 1. The four patents were registered to Motorola. Motorola then transferred the patents to Google sometime over the past year.
The other five patents were previously owned by Palm and Openwave before Google took ownership and passed them to HTC.

Apple is yet to file a formal complaint against Google regarding the patent, but it has an ongoing infringement case pending against Motorola Mobility.
