Accordant Energy, LLC v. Vexor Technology, Inc. et al.
In this lawsuit Accordant Energy accuses Vexor of infringing two patents relating to engineered feedstocks.
The patents are U.S. Patent Nos. 9,062,268 and 9,523,051, each entitled “Engineered fuel feed stock” and directed to feed stocks for use as gasification and combustion fuels and methods of making the feed stocks. Components derived from processed MSW waste streams are used to make the feed stocks, which are substantially free of glass, metals, grit and noncombustibles.
Filed February 28, 2017 in U.S. District Court for the Northern District of Ohio, the complaint names Vexor Engineered Fuel as the accused product.
Energy-Efficient Exercise Equipment
Green Fitness Equipment Co. v. Precor Inc.
It’s not every day you see patent litigation involving green exercising technology, but this one is about exactly that.
In a complaint filed February 8, 2017 in U.S. District Court for the Southern Distric of California, Green Fitness alleges that Precor has incorporated its patented invention into its EFC Elliptical Cross-trainer products that include Active Status Light technology.
The patent-in-suit is U.S. Patent No. 8,884,553, entitled “Current monitor for indicating a condition of attached electrical apparatus” (‘553 Patent).
The ‘553 Patent is directed to a current monitor that indicates a condition of attached electrical equipment. The current monitor can determine a predetermined range in which current being withdrawn by the attached electrical apparatus lies. Based on the determined range, corresponding display electronic elements, such as light emitting diodes (LEDs), can be activated.
The commercial embodiment of Green Fitness’s patented invention is its Treadmill Saver product.
Metrospec Technology LLC v. Hubbell Lighting, Inc.
This lawsuit was filed February 3, 2017 in U.S. District Court for the District of Minnesota. The complaint asserts three patents relating to high intensity flexible light circuits.
The asserted patents are directed to a layered structure comprising an electrically insulating intermediate layer interconnecting a top layer and a bottom layer. The top layer, the intermediate layer, and the bottom layer form an at least semi-flexible elongate member which is bendable laterally to a radius of at least 6 inches, twistable relative to its longitudinal axis up to 10 degrees per inch, and bendable to conform to localized heat sink surface flatness variations having a radius of at least 1 inch.
Metrospec alleges that the NorFlex product offered by Hubbell’s Thomas Research Products division infringes the patents.
Unity Opto Technology Co. v. Cree, Inc.
Unity Opto Technology Co. v. Cree, Inc.
Unity Opto Technology (UOT) sued Cree twice in January, seeking a declaratory judgement that Cree’s U.S. Patent Nos. 8,596,819 (‘819 Patent), 8,628,214 (‘214) Patent), 8,998,444 (‘444 Patent) and 9,052,067 (‘067 Patent) are invalid and that UOT does not infringe the ‘067 Patent.

The lighting device comprises at least one solid state light emitter, e.g., one or more light emitting diodes, and optionally further includes one or more lumiphor.
The ‘444 Patent is entitled “Solid state lighting devices including light mixtures” and directed to a solid state lighting apparatus including at least a first LED and a second LED. The first LED emits light in the blue portion of the visible spectrum and red light in response to the blue light. The second LED emits light having a color point that is above the planckian locus of a 1931 CIE Chromaticity diagram, and in particular may have a yellow green, greenish yellow or green hue.
Entitled “LED lamp with high color rendering index,” the ‘067 Patent is directed to an LED lamp that can emit light with a color rendering index (CRI) of at least 90 without remote wavelength conversion.
Solar Mounting Systems
Rillito River Solar, LLC v. Bamboo Industries LLC
In a lawsuit filed January 26, 2017 in U.S. District Court for the Eastern District of California, Rillito sued Bamboo Industries LLC dba SolarHooks for alleged infringement of three patents relating to solar mounting systems.
