Apple files more patent claims against HTC

After accusing HTC of infringing on 20 of its iPhone patents in March, Apple has expanded its suit.

This week Apple tacked on two more patents that it claims the Taiwanese handset manufacturer is in violation of using, according to a legal filing in U.S. District Court in Delaware.

The newly added patents both concern the same type of technology, which Apple lists as a "system for real-time adaptation to changes in display configuration."
