Apple on Tuesday asked the U.S. International Trade Commission to block the importation into the country of HTC's Google Android-based mobile phones, including the Google-branded Nexus One.

Apple asked the court for "a permanent exclusion order" that would bar from entry "all mobile communications devices and components" made by HTC that carry the offending technologies, according to court documents.

Apple on Tuesday sued HTC for alleged, multiple patent violations, claiming the Taiwan-based manufacturer's products infringe on its iPhone technology. Apple filed the actions with the ITC and the U.S. District Court for Delaware.

In the ITC filing, Apple says 11 HTC phones violate its patents, including the Nexus One, Touch Pro, Touch Diamond, Pure, Imagio, and myTouch 3G. Apple claims HTC infringed on a total of 20 patents governing a range of technologies.

Apple wants the ITC to block HTC and its partners from "importing, marketing, advertising, demonstrating, warehousing inventory for distribution, distributing, offering for sale" any of the listed phones.

Apple is also seeking unspecified monetary damages in the Delaware court.
