(AP) — A federal judge has barred the Nebraska attorney general from enforcing a cease-and-desist order issued against a Texas law firm.

Judge Joseph Batallion (buh’-TAL’-yuhn) ruled Monday that the order violated the constitutional rights of Activision TV, which had hired the law firm of Farney Daniels. Farney Daniels, of Georgetown, Texas, has been representing Activision in patent cases against businesses in Nebraska and other states.

Attorney General Jon Bruning said in July that the law firm appears to represent companies that bought up patents just so they could threaten lawsuits and collect settlements.

Bruning said Tuesday that the judge’s order addressed a relationship between Farney Daniels and its client. He says nothing in the order stops his office’s “investigations into patent trolls and law firms that represent them, specifically Farney Daniels.”
