Google and Oracle were ordered by Alsup on Aug. 7 to provide a list of bloggers, writers and authors who have commented on the patent suit and received money from either of the tech giants during the case. The filings were made public last Friday.
Both companies have denied paying commenters to write about their high-stakes patent battle. In its filing, Google listed nonprofits, universities, individuals and other organizations to which it has given contributions, but said it would be difficult to list them all.
Oracle noted that it hired Florian Mueller, author of the FOSS Patents blog, as a consultant "on competition-related matters," but did so after he started writing about the case.
"If a treatise author or blogger is paid by a litigant, should not that relationship be known?" Alsup continued.
A Google spokesman could not be reached for comment.
Oracle has accused Google's Android mobile platform of infringing on patents and copyright that belonged to its Java programming language.
