WASHINGTON Nano-Proprietary Inc. appears to have gained a significant legal victory in a dispute over a carbon nanotube patent.
A federal judge in Illinois has ruled that a company partner cannot gain control of a patent covering electron emissions from carbon nanotubes. U.S. District Court Judge Wayne Anderson granted Nano-Proprietary (Austin, Texas) injunctive relief that prevents partner Till Keesmann from gaining control over the patented technology.
Nano-Proprietary and Keesmann, a German citizen, concluded a patent licensing agreement in 2000. According to court documents, the deal gave Nano-Proprietary exclusive rights and a license covering Keesmann's carbon nanotube patent.
The company subsequently filed suit against Keesmann alleging that his attempts to terminate the licensing deal were invalid.
"Keesmann, his agents, employees and all those acting in concert with him will be enjoined from terminating the license agreement or otherwise acting in violation of the license agreement," Judge Anderson ruled in granting Nano-Proprietary an injunction to stop Keesmann.
Other than posting the ruling on its Web site, Nano-Proprietary had no immediate comment on the case.
The company has also been embroiled in a patent dispute with Canon over surface-conduction electron-emitter display patents. The intellectual property provider has a growing portfolio of granted and pending patents. Among them are basic patents for several emissive display technologies, including those using carbon nanotubes.
