Internet giant Google's video service faces at least one copyright infringement lawsuit, and the Web search leader faces a separate subpoena tied to the service, a Reuters report said.
Copyright infringement has become a hot topic as pirated video from TV, films and music videos has proliferated across the Web. Google runs its own service known as Google, the Reuters report said.
Video and last month agreed to buy video site YouTube for $1.65 billion.
Investors are concerned that Google could be financially liable for videos appearing on sites it runs, while the company has said it did not face financial recriminations if it acts quickly to take down copyrighted material once alerted to it, the report said.
A report on the Online Media Daily site said the lawsuit, which was filed in France, is seeking 150,000 euros ($193,000). It is related to a documentary video that appeared on Google Video, the media industry site said.
'This is a small lawsuit over a single video that appeared briefly,' Google spokesman Ricardo Reyes was quoted in a statement.
The lawsuit came to light in a US Securities and Exchange Commission filing in which Google listed Google Video among a number of businesses that were subject to legal action. It gave no details in the quarterly report. The Google spokesman declined to confirm further details of the suit, the Reuters report further said.
