"To me, a bigger concern is what Google is going to do to protect the whole ecosystem," Goldberg said.

It's unclear if Motorola's patents will be able to help Android device makers fend off the lawsuits against them. It depends how fast Google closes the acquisition and exactly what patents Motorola owns, Mixon said.

Samsung has already been hit with an injunction that blocks it from selling its Galaxy Tab in much of Europe, and the company may feel pressured to settle with Apple before Google's Motorola acquisition closes, Poltorak said.

Still, Google has made a significant step in the right direction, according to some observers.

"I see this as a meaningful deal, but it's just one more step in the process," Goldberg said.
