Intellectual Ventures, a large patent-licensing firm, has filed a second patent-infringement lawsuit against Motorola Mobility while its first patent lawsuit is still pending in a Delaware count.
The patent-licensing firm filed its second lawsuit against Motorola in U.S. District Court for the Southern District of Florida, the company announced Wednesday. The second lawsuit alleges that Motorola, owned by Google, has infringed seven different patents than the six named in the Delaware lawsuit.
Intellectual Ventures "has been unable to reach an agreement with Motorola" in the Delaware case, the company said in a statement.
The company also filed a patent-infringement lawsuit against banking firm Capital One in Virginia, Intellectual Ventures aid.
The lawsuits "are a necessary step in protecting our patent rights and fulfilling our commitments to our investors, inventors and licensees," Intellectual Ventures said.
Among the patents covered in the second lawsuit are ones related to methods to create and transmit information, including an address to further information; a system for ordering data messages with differing priority levels; and touchscreen systems.
A spokeswoman for Google didn't immediately respond to a request for a comment on the new lawsuit.
Some critics have accused Intellectual Ventures of being a so-called patent troll, but the company disputed that characterization.
"We're fighting to stop patent trolls' use of low-quality patents to extort money from companies that actually innovate and make real things," the company said in a statement. "We support bipartisan efforts by the White House and Congress to end these kinds of abuses."
In addition to buying and licensing patents, Intellectual Ventures also employs scientists and engineers working on inventions in several fields, including agriculture, computer hardware, life sciences, medical devices, semiconductors and software, the company said. The company files hundreds of patent applications every year, it said.
