Two more of Apple's patents have come under an "anonymous" re-examination request before the United States Patent and Trademark Office (USPTO). US patent 7,663,607 covering multipoint touch screens, and US patent 7,920,129 involving a "double-sided touch-sensitive panel" have been put up for review. Both patents were originally being asserted by Apple against Samsung, but were winnowed at the demand of Judge Lucy Koh's order to simplify and streamline the first Apple versus Samsung smartphone trial.
