(AP) — Nebraska’s attorney general is scheduled to testify before a U.S. Senate subcommittee on his opposition to the controversial practice of patent trolling.

Nebraska Attorney General Jon Bruning will testify Thursday before a subcommittee on consumer protection, product safety and insurance.

Patent trolling is a legal practice that critics say involves a company making deceptive claims of patent infringement in the hopes of collecting licensing or settlement money from another business. The contacted business will usually pay the requested fees to avoid the high costs of defending themselves in court.

Bruning issued a cease-and-desist order this summer against a Texas law firm that is representing a company with patent cases against businesses in Nebraska and other states. A federal judge barred Bruning’s order.
