It’s trivial, to be sure, but it’s not nothing. A New York judge ruled last week that a trivia book on “Seinfeld,” the Peacock sitcom “about absolutely nothing,” infringed on the show’s copyright.

“Though this seemingly invites the conclusion that this opinion is not about anything,” wrote U.S. District Judge Sonia Sotomayor, Castle Rock Entertainment’s charges of copyright infringement do have merit.

The subject of the suit is Beth B. Golub’s “The Seinfeld Aptitude Test,” put out by Carol Publishing Group Inc. Sotomayor was quick to note that the book, a compilation of more than 500 questions about the show’s events and characters, hasn’t lessened interest in “Seinfeld.” In fact, NBC has distributed copies of the book as part of its promotions, and executive producer George Shapiro even described it as a “fun little book.”

But the judge said Golub erred by copying facts from a work of fiction — the script. Damages will be set March 20.
