Judge Richard Posner of the U.S. District Court for the Northern District of Illinois "with prejudice," last month, denying requests from both companies for injunctions and ruling that neither party could resubmit the lawsuit.

Apple had filed a suit against Motorola, alleging that devices such as the Droid and associated software infringed on its patents. Motorola brought a counterclaim that Apple was infringing its own patents.

In separate filings Friday, Apple and Motorola Mobility appealed Posner's rulings, according to published reports.

Apple and Motorola were not immediately available for comment.

"Apple and Google subsidiary Motorola Mobility have both decided to appeal every single decision that Judge Posner made that wasn't in their favor," said legal analyst and consultant Florian Mueller in a Saturday. "They leave no stone unturned." Mueller has been tapped as a consultant for tech companies including Oracle and Microsoft.
