Harper Lee is suing an Alabama museum in her hometown, the town that inspired the setting of her "To Kill a Mockingbird," accusing it of violating her trademark and persona, according to news reports.

The complaint, which was filed by Lee, 87, on Oct. 10 in Monroeville, Ala., alleges the Monroe County Heritage Museum has been illegally profiting from the Pulitzer Prize-winning novel that was published in 1960.

She objects to claims made in IRS documents that the museum's mission is historical, according to the Hollywood Reporter.

"Its actual work does not touch upon history," according to the complaint Lee filed. "Rather, its primary mission is to trade upon the fictional story, settings and characters that Harper Lee created in 'To Kill a Mockingbird,' and Harper Lee's own."

The lawsuit contends the museum earned more than $500,000 in 2011 by selling goods including kitchen towels, aprons and clothing emblazoned with the book's title. The museum has since responded to Lee's suit.

Matthew Goforth, an attorney for the museum, told ABC News the museum is within its rights to carry out its mission as it always has.

"Every single statement in the lawsuit is either false, meritless, or both," he said. "It is sad that Harper Lee's greedy handlers have seen fit to attack the nonprofit museum in her hometown that has been honoring her legacy and the town's rich history associated with that legacy for over 20 years."

In her lawsuit, Lee said she felt like her hometown, where she currently resides, has been trying to profit off of her fame.

"The town's desire to capitalize upon the fame of 'To Kill A Mockingbird' is unmistakable," Lee said in the lawsuit. "Monroeville's town logo features an image of a mockingbird and the cupola of the Old County Courthouse. Which was the setting for the dramatic trial in [the movie] 'To Kill A Mockingbird."

"To Kill a Mockingbird" has sold more than 30 million copies and has been translated into more than 25 languages. It is considered an American classic.

Lee has only published one book.

This lawsuit against her hometown museum comes merely weeks after Lee settled a dispute in which she alleged she was "duped" into signing over the copyright to "To Kill a Mockingbird".
