'Peanuts' Music Owner Targets Government, Companies In Copyright Blitz: Report

SONOMA COUNTY, CA — The jazzy piano melodies that helped turn “Peanuts” television specials into holiday rituals have landed at the center of a sweeping copyright fight.

Four federal lawsuits accusing companies and the U.S. government of exploiting the music behind “A Charlie Brown Christmas” without permission were filed by Lee Mendelson Film Productions, according to reports by CBS News and other outlets.

The lawsuits, filed Wednesday in federal courts in New York and Washington, D.C., target the U.S. Department of the Interior, GameMill Entertainment, Heritage Auctions and Buckle-Down Inc., CBS News reported.

The company claims the defendants used music tied to the classic “Peanuts” television specials in social media campaigns, promotional videos, merchandise and a video game without securing licenses, according to reports.

At the center of the legal battle are Guaraldi’s instantly recognizable compositions, including “Linus and Lucy,” the swinging piano theme that became synonymous with Charlie Brown and Snoopy, and his arrangement of “O Tannenbaum” from A Charlie Brown Christmas.

One lawsuit accuses the United States Department of the Interior of using Guaraldi’s “O Tannenbaum” arrangement in a digital holiday card shared on social media without authorization, according to reports by the Associated Press.

Another alleges Heritage Auctions used “Linus and Lucy” in Facebook and Instagram promotions tied to a collectibles auction. The complaint against Buckle-Down Inc. makes similar claims involving social media promotions connected to “Peanuts”-themed products.

The fourth lawsuit targets GameMill Entertainment over the 2025 game Snoopy & The Great Mystery Club. The complaint argues the publisher created soundalike compositions deliberately modeled after Guaraldi classics such as “Linus and Lucy” and “Skating,” crossing the line from inspiration into copyright infringement, according to reports.

Attorney Marc Jacobson, representing Lee Mendelson Film Productions, said the company acted after confronting what it described as an “intolerable digital glut” of unauthorized uses spreading rapidly online, CBS News reported.

“Lee Mendelson Film Productions will no longer tolerate companies using their property without a license, especially in this era of instant digital sharing,” Jacobson said in a statement. He added that “the rights of creators and the protection of iconic cultural assets must be vigorously enforced," according to reports.

The plaintiffs are seeking financial damages and court orders blocking future uses of the music. One filing seeks at least $300,000 from GameMill Entertainment alone, according to reports.

A representative for Heritage Auctions told CBS News the company had not yet reviewed the complaint and would respond after being served.

Notably absent from the litigation is Peanuts Worldwide LLC, which controls the rights to Charlie Brown, Snoopy and the rest of the “Peanuts” characters but is not named in any of the lawsuits.

Santa Rosa is home to the Charles M. Schulz Museum & Research Center, which claims the largest collection of original Peanuts comic strips in the world.

For decades, Guaraldi’s cool jazz scores transformed animated children’s specials into cultural landmarks. Now the owners of that music catalog are signaling they intend to defend every note.
