The Book Search settlement, announced in October, followed a three-year battle over Google’s right to display copyrighted books on its Web site. The Authors Guild and the Association of American Publishers claimed Google was violating copyrights by doing so. Google eventually agreed to pay $125 million to ensure authors and publishers could register to receive payments anytime their books were viewed within the service.

The deal is proving to be quite divisive, and now, with the Justice Department’s reported antitrust investigation, things could get even more dicey. Here’s a look at five key arguments from both sides of the debate.

But recent findings reveals that the judge who ruled against The Pirate Bay defendants on Friday is a member of two copyright organizations, an alleged conflict of interest that could require the case to be tried again.

Norström is a member of the Swedish Copyright Association and the Swedish Association for Industrial Legal Protection. Both organizations say their goal is to educate about copyright issues. Norström denies accusations that the memberships would make him biased.

Unlike the case of Napster, The Pirate bay doesn’t actually host the copyrighted files, it simply allows users to posts links to copyrighted files on third party servers.  That’s why the they were charged of “assisting making available copyrighted material” instead of “assisting copyright infringement”

Could this be the end of torrent file sharing? And how about other torrent search engines, could they be next, If simply posting links to copyrighted materials can be charged of “assisting making available copyrighted materials”, surely there are many sites that fits this profile. One problem is, most of the links to copyrighted materials are posted by users and not necessarily the owners of site.

How about Online file sharing sites like rapidshare, megaupload, easyshare and others, Some of it’s users upload copyrighted materials, Even though they deleted files if found to be in violation of their terms of service. Problem is how to determine if the files are copyright, as most of the uploaded files are archived and renamed. Are the owners of the site also liable?

And One Big question, since Google, Yahoo, MSN Live.com also indexes copyrighted materials, are they also liable?

The suit seeks to terminate Intel’s license to Nvidia’s patents related to graphics processing and three-dimensional computing and comes in response to a related suit by Intel last month.

Nvidia believes that without a licensing agreement, Intel’s line of integrated graphics chips violate Nvidia’s patent portfolio, according to Nvidia spokesman Hector Marinez.

The complaint represents the latest salvo in an escalating feud between the two chipmakers that has moved from the marketplace to the courtroom.

The disagreement stems from the fact that Intel’s new generation of Nehalem microprocessors feature an integrated memory controller. According to Intel, the 2004 licensing agreement only covers its previous generation of products, in which the memory controller was separate from the microprocessor.
