The ongoing talks between Yahoo and Facebook in an attempt to resolve their long-running patent litigation battle have apparently been fruitful, as AllThingsD reported that the two Internet giants have reached an agreement.

Yahoo and Facebook are trying to put an end to a legal saga in which the web portal sued the social network for patent infringement. Yahoo claimed in March that Facebook essentially stole its social network model, which includes creating profiles and interacting with other users and businesses. Both sides were in court again Tuesday, as Yahoo asked for a two-week extension to file replies in the lawsuit.

Executives from Yahoo and Facebook have been in negotiations to end their patent litigation battle, started by a suit Yahoo filed against Facebook in March, with the two companies exploring cross-licensing of patents and deeper integration between the search engine and the social network, according to reports.

Will a new chief executive officer bring new hopes for a settlement in the patent-infringement brouhaha between Yahoo and Facebook? Yahoo Interim CEO Ross Levinsohn reportedly reached out to the social network in hopes of a settlement, after taking over for former CEO Scott Thompson.

Facebook got some good news today on the patent-litigation front, not related to its squabble with Yahoo, but involving a patent suit originally filed in November 2008 by Leader Technologies.

The fifth amendment to Facebook’s initial public offering filing contained a warning that Yahoo found 16 more patents that “may be relevant” to the patent-infringement lawsuit it filed against Facebook in March.

The latest volley in the unpopular patent-infringement lawsuit Yahoo filed against Facebook last month was fired by Yahoo, which claimed in a court filing today that it is not infringing on any of Facebook’s patents, along with adding two more of its own patents to the list of those allegedly being violated by the social network.

Remember that May 17 date for the Facebook initial public offering that was widely reported last week? We would advise writing that in pencil, and not ink.

Facebook reached an agreement with Microsoft to acquire about 650 of the 925 or so patents and patent applications the software giant acquired from AOL earlier this month.
