Thursday, Research In Motion Limited (RIMM) announced that its quarterly earnings came in at $1.46 per share, compared to 83 cents per share a year ago. Not only did the results top those from a year ago, but the results topped analysts' expectations for $1.36 per share.

Turning to revenue, RIM raked in $4.62 billion, 31% better than a year ago as well as better than estimates for $4.49 billion.

During the quarter, the company shipped 12.1 million smartphone units and added 4.5 million new subscribers. While the new subscribers came in short of the expected 5 million, the 12.1 million shipped units was better than the forecast 11.8 million.

Monday morning, mobile phone firm Motorola (MOT) found itself on the lips of lawyers and judges. The first reason is that a lawsuit commenced in the U.S. District Court for the Northern District of Illinois on behalf of MOT stock purchasers who made their purchase from December 6, 2007 through January 22, 2008.

The lawsuit alleges that Motorola and "certain of its officers and directors" violated federal securities laws by "intentionally and knowingly misstating the 2007 fourth quarter earnings projections and sales demands for the RAZR2 during the 2007 holiday shopping season." The suit states that Motorola's RAZR2 did not attract buyers thanks to its $299 price tag and the fact that it had not improved enough from the RAZR. Nevertheless, Motorola made positive statements all while losing "significant market share" to its competition. The defendants claim that Motorola senior execs knew that Motorola was not on track to hit their profit forecast of 12 cents to 14 cents per share, and would like a bit of compensation.

Eastman Kodak (EK) is grabbing headlines after the film firm filed a complaint with the U.S. International Trade Commission (ITC), alleging that Apple's (AAPL) iPhone and Research In Motion Limited's (RIMM) BlackBerry camera phones infringe on Kodak's patents. Kodak is asking the ITC to block Apple and RIMM from importing the offending devices.

Additionally, the iconic photography company filed two suits against Apple in the U.S. District Court for the Western District of New York. Kodak is claiming infringement of patents "related to digital cameras and certain computer processes."
