An Adelaide woman who is suing internet giant Google for defamation has had a partial win in the case, which will now proceed to another trial in the South Australian Supreme Court.

Dr Janice Duffy claims articles published on the "Ripoff Report" website since 2007 defamed her, and Google had denied her request to remove the material from the search engine.

She said any prospective employer would use the search engine to research her, and it had caused her financial and psychological damage.

After she filed the civil proceedings against Google in 2011, the company then progressively took the material down from its Australian website.

Dr Duffy claimed an auto-complete search term that Google offered with searches of her name was also defamatory.

Google denied the publications or any material linked from its website were defamatory and relied on several defences, including justification.

In his 144-page judgment Justice Malcolm Blue struck out several of the defences presented by Google's lawyers.

He ruled that Google did publish defamatory material about Dr Duffy and ordered the case proceed to trial on the remaining unresolved issues.

"The defences of innocent dissemination, qualified privilege justification (except as to the misuse of government email) and contextual truth fail," Justice Blue said.

"It is necessary to proceed to trial on the remaining issues, being the defences of triviality and time limitation, the application for an extension of time, and causation and quantum of damages."

Dr Duffy wept as Justice Blue said the material was defamatory.

She also broke down as she told the court she was "exhausted" from the proceedings and needed more time to prepare for the trial.

"I'm beyond exhausted... I haven't slept in days," she said.

The case will return to court on November 3.
