Nokia's plans to get into the touch-only tablet market were supported on Tuesday by two patent filings published by the USPTO. Both are thin, full-touch designs but vary sharply in their looks. The first, D634,317, takes its cues from modern Nokia Symbian phones like the N8 and E7; the second, D634,318, is slightly more conventional and has a U-shaped shell where the main body fills in the gap.
