"Does this refer to the WP's suit against Jim and FR where the post also won a summary judgement?"
No. In a way it's the other way around. The WP was sued by someone else for copyright infringement:
"In an early Internet-related case, Proskauer -- with Chris serving as lead counsel -- obtained summary judgment on behalf of The Washington Post and two of its reporters in a federal lawsuit brought by the Religious Technology Center alleging copyright infringement and theft of trade secrets and involving important First Amendment issues."
