Oracle seeks billions in Google lawsuit

Oracle has put a multibillion-dollar price tag on its claim that Google built the popular Android software by using some of Oracle's Java code without permission, according to documents filed in San Jose federal court.

Google is disputing Oracle's claims for patent and copyright infringement, but recent court filings indicate Oracle is seeking a share of Google's extensive advertising revenue in damages for the alleged violations. The case is being watched closely in the tech world because it could have broad implications for the commercial software and mobile computing industries. Oracle acquired rights to the widely used Java programming language when it bought Sun Microsystems last year. Google, meanwhile, has made its Android operating system into one of the most popular platforms for smartphones and tablets in the world. The two tech giants have been wrangling in court for months, attempting to define complex technical and financial issues before a scheduled trial date this fall. Many of their arguments have been filed under seal, on the grounds they concern proprietary business information.
