Several new green patent complaints were filed in July and August in the areas of advanced batteries, electrolyzers for sewage treatment, LED lighting, eco-friendly pet products, solar powered trash compactors, and wind turbines.
Advanced Batteries
Somaltus LLC v. Universal Power Group
Somaltus LLC v. Tenergy Corporation
Somaltus LLC v. Maxim Integrated Products, Inc.
On July 26, 2017 Somaltus, a non-practicing entity, filed three patent infringement lawsuits against Universal Power Group (Somaltus v. Universal Power Group), Tenergy (Somaltus LLC v.

Marine Sewage Treatment
DeNora Water Technologies Texas, LLC v. H2O, Inc.
This lawsuit involves bookcell electrolyzer technology used for oxidizing sewage.
The asserted patent is U.S. Patent No. 6,379,525, entitled “Enhanced electrolyzer” and directed to an electrolyzer including a housing having an inlet and an outlet at a common end. Within the housing are disposed electrode elements, a passageway that connects the inlet to the outlet, and a divider is disposed in the passageway between the inlet and outlet. The divider causes fluid entering the inlet to flow through one section of the passageway and then through another section of the passageway before exiting through the outlet.
The complaint was filed August 17, 2017 in federal court in Houston, Texas, and lists Defendant’s multi-pass bookcell electrolyzers as the accused products.

The ‘558 Patent is entitled “LED mount bar capable of freely forming curved surfaces thereon” and directed to an LED tape light strip with a structure that allows it to be bent in the direction of its width so it can be used for lighting that must conform to unique shapes.
The accused product listed in Bitro's complaint is Defendant’s CurrentControl Bendable ZigZag LED Strip Light.
Blackbird Tech LLC v. Ontel Products Corporation
Filed August 23, 2017 in U.S. District Court for the District of New Jersey, Blackbird’s complaint alleges that Ontel Products infringes U.S. Patent No. 6,883,927 (‘927 Patent).
Entitled “Frame assembly and light for an electrical wall conduit,” the ‘927 Patent is directed to a frame assembly for covering a wall conduit having a connection to electrical power. The frame assembly comprises a light powered by an electrical circuit connected to the connection and a frame for housing the light. The frame has an opening allowing access to the component through the frame, a side and an aperture in the side allowing the light to illuminate a space outside the frame assembly through the aperture.
The accused products are Ontel’s Night Angel electrical wall outlet covers.
Document Security Systems, Inc. v. Lite-On, Inc. et al.
Document Security Systems (DSS) filed this lawsuit against Lite-On August 15, 2017 in U.S. District Court for the Central District of California asserting three LED patents.
The complaint contains a long list of accused products, e.g., many of Lite-On’s PLCC Series LED products, including both single color and multi-color lights.
The asserted patents are:
U.S. Patent No. 6,949,771, entitled “Light source”
U.S. Patent No. 7,524,087, entitled “Optical Device”
U.S. Patent No. 7,256,486, entitled “Packing device for semiconductor die, semiconductor device incorporating same and method of making same”
Technical LED Intellectual Property, LLC v. Osram Sylvania Inc.
Technical LED IP sued Osram on August 9, 2017 for alleged infringement of two patents relating to phosphor-based LED lights. The complaint was filed in U.S. District Court for the District of Delaware.
The asserted patents are U.S. Patent Nos. RE41,685 (‘685 Patent) and 6,373,188 (‘188 Patent).
The ‘685 Patent is entitled “Light source with non-white and phosphor-based white LED devices, and LCD assembly” and directed to a light source incorporating phosphor-based white and non-white LEDs, which may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. A reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward, and the LEDs may be skewed in relation to adjacent LEDs to reduce interference.
Entitled “Efficient solid-state light emitting device with excited phosphors for producing a visible light output,” the ‘188 Patent is directed to a solid-state light emitting device in which phosphors excited by radiation produce visible light. The efficiency of the device is increased by providing a reflector adjacent to the phosphor layer for reflecting at least some of the radiation that passes through the phosphor back into the phosphor. The reflector may also reflect at least some of the visible light that is emitted by the phosphor toward a designated light output.
The accused products include, among others, Osram’s LEP-2100-840-HD-C, LEP-2100-930-HD-C, LEP-800-840-HD-C, LEP800-930-HD-C, LED12A19/DIM/F/927, LCW CP7P-KPKR-5R8T, and LE CW E3B-NYPZ-QRRU models.

The temperature regulation layer is adapted to hold a composition and has a plurality of angled segments, wherein angled segments within a sealed perimeter of the temperature regulation layer are formed by a top side and a bottom side at a predefined distance, and channels, wherein the channels substantially form sides by contacting the top side with the bottom side at a distance lesser than the predefined distance.
The complaints allege that the defendants’ respective cooling mat products infringe the two patents.
Solar Powered Trash Compactors
BigBelly Solar, Inc. v. Ecube Labs Co.
In this lawsuit filed July 28, 2017 in U.S. District Court for the Central District of California, BigBelly asserts two patents relating to solar powered compaction technology.
U.S. Patent Nos. 7,124,680 and 7,481,159 are related patents, each entitled “Solar powered compaction apparatus” and directed to a trash compactor powered by a photovoltaic cell array. The compaction feature allows the unit to be emptied less often than a typical trash container.
