The accused products and services are Nexgrid products sold under the Nexgrid Technology Solutions brand name, Freewave’s Comprehensive High-Speed Wireless M2M Communications Solution sold under the WavePoint brand name, and Zenner’s Stealth and MeshPlus branded products and services.

 

Solar Power

D Three Enterprises, LLC v. Sunmodo Corporation

D Three Enterprises, LLC v. Rillito River Solar LLC

On June 2, 2015 D Three filed two patent infringement suits in the U.S. District Court for the District of Colorado.

In the first (D Three Enterprises v. Sunmodo), D Three accuses Sunmodo of infringing U.S. Patent Nos. 8,689,517 (‘517 Patent) and 8,707,655 (‘655 Patent), both relating to involving sealing assemblies for roof-mounted solar panels.

The ‘517 and ‘655 Patents are related patents, each entitled “Roof mount sealing assembly” and directed to roof mount sealing assemblies that allow a user to mount rails for solar panels, signs, satellite dish or any other desired item on the roof and have the mounting location sealed against water.

The accused Sunmodo products are the EZ Mount assembly with Standoff for Shingle Roofs and the EZ Mount L-Foot Kit for Shingle Roofs.

The D Three complaint against Rillito asserts only the ‘517 Patent and alleges that Rillito’s (dba EcoFasten Solar) QuikFoot Roof Mount System with P-3-CSK Compression Post infringes the patent.

 

Allsop, Inc. v. Jetmax Ltd.

Allsop, a manufacturer of various consumer products including collapsible solar power lanterns, sued Hong Kong-based Jetmax for infringement of U.S. Patent No. 8,657,461 (‘461 Patent).

The ‘461 Patent is entitled “Solar-powered collapsible lighting apparatus” and directed to a solar-powered lighting apparatus having a light transmissible spherical shade coupled to a housing that receives a solar cell, a battery and at least a portion of a lighting element assembly.

Filed May 29, 2015 in federal court in Seattle, Washington, the complaint alleges that Jetmax’s Nylon Solar Hanging Lantern infringes the ‘461 Patent.

 

Vinson Conlan’s LED Patent Report: What’s at Stake in Cree v. Feit?

July 7th, 2015

A previous post reported on the LED patent lawsuit between North Carolina LED manufacturer Cree and Feit Electric Company in which Cree has alleged infringement of a number of utility and design patents.

There are several patents involved with this case but none as far reaching as U.S. Patent No. 8,596,819 (‘819 Patent). Let’s look at the first claim:

1.  A lighting device comprising at least one light emitting diode, said lighting device, when supplied with electricity of a first wattage, emitting output light with a wall plug efficiency of at least 60 lumens per watt of said electricity.

This claim covers all LED devices with an efficacy over 60 lumens per watt with at least one LED.

The latest Energy Star luminaire requirements (taking effect in 2016) for all luminaire categories, but track need to meet or exceed 60 LPW. Most large retailers have relied upon Energy Star to help qualify products for sale to residential customers. In some cases, products without Energy Star will not be considered for sale in retail outlets.

Energy Star is required to qualify for many utility rebate programs. Energy Star is a Department of Energy program and has been made aware of the ‘819 Patent. They were made aware of this patent issue before the latest luminaire requirements were finalized.

Those who honor the ‘819 Patent would be denied rebate dollars and the potential to sell into some large volume accounts because meeting Energy Star requirements would force them to infringe the patent.

Energy Star has the best interest of the country in mind, but one has to question their decisions when their policies will clearly steer rebates dollars and retail business directly towards a single patent holder.

This case is about more than one company against another, it is the test of a patent that could be used successfully to deny businesses the opportunity to get an Energy Star listing and qualify for rebate dollars.

For those looking to sell into the commercial channel and get added to the Design Lights Consortium (DLC) qualified product list, they will only qualify for display case lighting and directional interior categories. All lamps would infringe as well. Like Energy Star, DLC qualified products are eligible for rebates.

Another Cree patent in this lawsuit is U.S. Patent No. 8,628,214 (‘214 Patent).  This patent is very similar to the ‘819 Patent. The first claim of the ‘214 Patent reads:

 1.  A lighting device comprising:a first string of solid state light emitters in series, the first string comprising at least two solid state light emitters,

a second string of solid state light emitters in series, the second string comprising at least two solid state light emitters,

a third string of solid state light emitters in series, the third string comprising at least two solid state light emitters,

the lighting device, when supplied with electricity of a first wattage, emitting output light with a wall plug efficiency of at least 60 lumens per watt of the electricity.”

Perhaps it is time for those who support Energy Star and DLC to consider a revised set of efficacy standards that promote free trade and offer their customers a wider range of options. The following organizations have influence, and as objective third parties can help all interested parties find solutions that will help save energy without infringing these patents.

Jury Verdict for Everlight Knocks Out Nichia Patents

May 13th, 2015

 

A previous post discussed the declaratory judgment complaint (Everlight-Nichia ComplaintEverlight Electronics filed against Nichia in federal court in Michigan in April 2012.

Everlight sought declaratory judgment of non-infringement, invalidity, and unenforceability due to inequitable conduct of two patents owned by Nichia:  U.S. Patent Nos. 5,998,925 entitled “Light Emitting Device Having a Nitride Compound Semiconductor and Phosphor Containing Garnet Fluorescent Material” (’925 Patent), and 7,531,960 entitled “Light Emitting Device with Blue Light LED and Phosphor Components” (’960 Patent).

Everlight suffered a setback later that year when the court granted Nichia’s motion to dismiss the inequitable conduct claims.

However, the Taiwanese company scored a big victory recently when the Michigan jury unanimously found multiple claims of the ‘925 and ‘960 Patents invalid.  More particularly, claims 2, 3 and 5 of the ‘925 Patent were found to be invalid due to obviousness, claims 2, 14 and 19 of the ‘960 Patent were found to be invalid due to obviousness, and claims 14 and 19 of the ‘960 Patent were also found invalid for lack of enablement.

The jury declined to find claims 2, 3 or 5 of the ‘925 Patent to be invalid on the additional enablement ground.

While this is an important win for Everlight, it is just one battle in a sprawling patent war between these two LED rivals.  The litigation dates back to 2005 when Nichia first targeted Everlight for patent infringement and extends to various venues around the world.

Nichia has sued an Everlight customer in a Tokyo District Court asserting the Japanese counterpart to the ‘960 Patent (Japanese Patent No. 4350094).  Nichia also filed suit against Everlight in Germany asserting the European counterpart to the ’925 Patent (European Patent No. EP 0 936 682).

In addition to this DJ action, Everlight has filed a number of reexaminations proceedings targeting Nichia’s LED patents.

Trade Secrets Lit Updates: Sinovel Challenges Summons Service and Philips Computer Fraud Claim Fails

April 29th, 2015

There are updates on a couple of green tech trade secrets cases, each involving allegations of misappropriation by Chinese companies and their employees.

First, as discussed in a previous post, the ongoing litigation between American Superconductor (AMSC) and Sinovel includes a criminal indictment against the Chinese wind turbine maker, two of its employees, and a former AMSC employee.

The defendants are charged with conspiracy to commit trade secret theft and criminal copyright infringement.  The technology involved is AMSC’s source code, software, equipment designs and technical drawings that relate to regulating the flow of electricity from wind turbines to the electricity grid

In a recent oral argument, Sinovel asked the U.S. Court of Appeals for the Seventh Circuit to reverse a lower court ruling and quash a summons, arguing it was improperly served on its U.S. subsidiary.  An article about the oral argument can be found here.

The second is a lawsuit brought by Koninklijke Philips and Philips Lumileds against Chinese competitor Elec-Tech International (ETI), several ETI subsidiaries, two corporate directors, and a former Lumileds employee named Dr. Gangyi Chen.  Philips alleged theft of trade secrets relating to high-energy LED lighting technology.

Elec-Tech moved to dismiss the complaint for a number of reasons, including an inadequately pleaded claim under the Computer Fraud and Abuse Act (CFAA), the only federal cause of action in the case.

In a recent decision, a federal court in San Jose, California dismissed Philips’ case, holding that the federal law claim under the CFAA could not be sustained.

The CFAA prohibits various computer crimes related to accessing computers without authorization in order to obtain information or data.  The problem for Philips was that Dr. Chen, who was alleged to have stolen the trade secret information, was authorized to access the Philips Lumileds network and did not exceed his authorized access while downloading the information prior to his resignation.

Specifically, the complaint was deficient because it lacked any allegation that someone without authorization accessed the confidential information:

By the Complaint’s own allegations, none of the CFAA Defendants accessed Lumileds’ information – Dr. Chen did, at a time when he was authorized to download this information.

While Dr. Chen may have misappropriated the information (a state law claim) and given it to the CFAA Defendants, the court held there is no “claim against those Defendants under the CFAA because they themselves did not hack Lumileds’ system.”

The court rejected Philips’ argument that Dr. Chen was an “agent” of the CFAA Defendants and they should be held liable based on their indirect, unauthorized access through Dr. Chen’s access, holding that the CFAA Defendants lack of access was fatal to the claim:

None of the CFAA Defendants entered or used Lumileds’ network.  At most, they encouraged Dr. Chen to do so, and stood to benefit from alleged misappropriation.  This action may give rise to a number of claims, but it does not support a theory of liability under the CFAA.

Expect this case to start up again in state court.

BASF Brings Battery Battle to the Border

April 14th, 2015

A previous post reported that chemical giant BASF and UChicago Argonne LLC (Argonne) sued Belgium-based Umicore and Japan-based Makita Corporation for infringement of two patents relating to cathode materials for lithium-ion batteries.  That lawsuit was filed February 20, 2015 in the U.S. District Court for the District of Delaware.

The same day BASF and Argonne filed a complaint in the U.S. International Trade Commisson (ITC) asking the ITC to investigate whether Umicore, Makita and their U.S. subsidiaries have imported and sold in the United States lithium ion cathode materials and batteries that infringe the same patents.

The ITC is a federal agency that investigates trade and importation issues, including conducting quasi-judicial proceedings involving alleged infringement of intellectual property rights by importation of accused products pursuant to 19 U.S.C. § 1337.  It is a popular forum for patentees (though only injunctive relief is available, not monetary damages) because the proceedings progress much faster than those in the federal courts.

The patents-in-suit are U.S. Patent Nos. 6,677,082 (’082 Patent) and 6,680,143 (’143 Patent), both entitled “Lithium metal oxide electrodes for lithium cells and batteries” and directed to a lithium metal oxide positive electrode for a non-aqueous lithium cell.

The cell is prepared in its initial discharged state and has a general formula xLiMO2.(1−x)Li2M′Oin which 0<x<1, and where M is one or more ion with an average trivalent oxidation state and with at least one ion being Mn or Ni, and where M′ is one or more ion with an average tetravalent oxidation state.

According to the ITC complaint, Argonne is the owner of the ‘082 and ‘143 patents and BASF produces lithium ion cathode materials under an exclusive license to the patents.

Recently, the ITC issued a Notice announcing that it would investigate BASF’s and Argonne’s claims of infringement.

BASF and Argonne have requested a limited exclusion order that would prevent Umicore and Makita from importing Umicore’s cathode materials, allegedly marketed and sold under the Cellcore product group, and certain Makita power tools using lithium ion batteries.

Although Umicore and Makita are now squeezed in both the ITC and federal court, they may ask the court to stay the parallel court action in view of the ITC investigation.

Big Win for Butamax as PTAB Knocks Out All Claims of Gevo Patent

April 6th, 2015

Previous posts (e.g., here and here) discussed various threads of the major biofuels patent litigation between BP-DuPont joint venture Butamax and the advanced biofuels company Gevo.

A relatively new mechanism for challenging the validity of a U.S. patent is inter partes review (IPR), an administrative trial proceeding before the U.S. Patent and Trademark Office’s (USPTO) Patent Trial and Appeal Board (PTAB) in which a third party can challenge the validity of a patent based on printed prior art publications.

Last year Butamax filed a petition with the PTAB for IPR of Gevo’s U.S. Patent No. 8,546,627 (‘627 Patent).  The ‘627 Patent is entitled “Renewable compositions” and directed to processes for preparing a renewable jet fuel.

The claimed processes comprise fermenting biomass with a microorganism, dehydrating the resulting alcohol to form biofuel precursors, and then subjecting the biofuel precursors to processes such as oligomerization, hydrogenation, and aromatization to form the fuel.

In a recent decision, the PTAB ruled that all 21 claims of the ‘627 Patent are invalid in view of several prior art references cited by Butamax.

More particularly, the PTAB held that U.S. Patent Application Publication No. 2008/0132741 to D’Amore discloses five of the seven steps of independent claim 1 of the ‘627 Patent.  Because the sixth and seventh steps of claim 1 are recited as optional, D’Amore was found to anticipate the claims.  D’Amore was also held to anticipate dependent claims 7, 11 and 14 of the ‘627 Patent.

As the primary prior art reference, the PTAB applied D’Amore in combination with several other printed publications in holding all of the claims invalid.  The PTAB also considered ASTM D1655 jet fuel standards as an important secondary reference and found that D’Amore in combination with the standards rendered claims 2-7, 11, 14 and 18-21 obvious.

The PTAB found an additional ground for invalidity of independent claim 18 in International, or PCT, Patent Publication No. WO 2007/061903 to Bradin.  Bradin is entitled “Alternative fuel and fuel additive compositions” and directed to alternative gasoline, diesel fuel, marine diesel fuel, jet fuel, and flexible fuel compositions including an alcohol and/or a glycerol ether or mixture of glycerol ethers, which can be derived from renewable resources.

Clean Tech in Court: Green Patent Complaint Update

March 24th, 2015

In January and February, there were a number of green patent infringement lawsuits filed in the areas of biofuels, hybrid vehicles, LEDs, smart grid, advanced batteries, solar power, and water meters.

Advanced Batteries

BASF Corporation et al. v. Umicore N.V. et al.

In this lawsuit BASF and UChicago Argonne, LLC accuse Umicore and Makita Corporation of unfair trade practices, antitrust violations, and infringement of two patents relating to cathode materials for lithium-ion batteries.

The patents-in-suit are U.S. Patent Nos. 6,677,082 (‘082 Patent) and 6,680,143 (‘143 Patent), both entitled “Lithium metal oxide electrodes for lithium cells and batteries” and directed to a lithium metal oxide positive electrode for a non-aqueous lithium cell.

The cell is prepared in its initial discharged state and has a general formula xLiMO2.(1−x)Li2M′Oin which 0<x<1, and where M is one or more ion with an average trivalent oxidation state and with at least one ion being Mn or Ni, and where M′ is one or more ion with an average tetravalent oxidation state.

According to the complaint, Umicore is selling cathode materials that infringe the ‘082 and ‘143 Patents, and Makita is one of the companies importing and selling batteries incorporating the materials.  The lawsuit was filed February 20, 2015 in the U.S. District Court for the District of Delaware.

Biofuels

C T E Global, Inc. v. Novozymes A/S

In a complaint filed January 9, 2015 in the U.S. District Court for the Northern District of Illinois, C T E Global seeks a declaratory judgment of invalidity and non-infringement of two Novozymes patents relating to an enzyme used in biofuel production.  The patents are U.S. Patent Nos. 6,255,084 (’084 Patent) and 7,060,468 (’468 Patent).

The ’084 and ’468 Patents are entitled “Thermostable glucoamylase” and are directed to an isolated glucoamylase enzyme which has higher thermal stability than prior glucoamylases.  The patents also claim starch conversion processes using the enzyme.  Glucoamylases are used to convert hydrolyzed corn starch to glucose, particularly in production of ethanol.

Novozymes and C T E previously litigated these patents and settled the case in 2012.  According to C T E, the ‘084 and ‘468 Patents are invalid in light of the U.S. Supreme Court Myriad Genetics decision holding that isolated natural products are not patent eligible subject matter.

Superior Oil Company, Inc. v. Solenis Technologies L.P.

This is not a patent infringement suit, but rather a priority /ownership dispute in which Superior Oil claims that the inventors of its patent for a method for recovering oil from the byproducts of ethanol production using various surfactants were the first to invent the technology.

Superior Oil’s patent is U.S. Patent No. 8,962,059, entitled “Bio-based oil composition and method for producing the same” (‘059 Patent).  In its complaint, Superior Oil requests that the court declare that an interference-in-fact exists between the ‘059 Patent and U.S. Patent No. 8,841,469 (‘469 Patent), entitled “Chemical additives and use thereof in stillage processing operations” and owned by Solenis Technologies.

The complaint was filed February 24, 2015 in the U.S. District Court for the District of Delaware.

Hybrid Vehicles

Somaltus LLC v. Ford Motor Company

Somaltus filed this complaint for patent infringement in the U.S. District Court for the Eastern District of Texas on February 12, 2015.  Somaltus alleges that Ford infringes U.S. Patent No. 7,657,386 (‘386 Patent) by selling vehicles equipped with an infringing hybrid battery system.

The ‘386 Patent is entitled “Integrated battery service system” and directed to an integrated battery service system that performs a plurality of services related to a battery, such as battery testing, battery charging, and the like. In addition, the integrated service system provides services to devices/components that are coupled to the battery, such as starters, alternators, etc.

Somaltus, a non-practicing entity, has also sued Nissan, Bosch Automotive Service Solutions, Auto Meter Products, and Cadex Electronics.

Beacon Power, LLC v. SolarEdge Technologies, Inc. et al.

Beacon Power sued SolarEdge for patent infringement on January 9, 2015 in federal court in San Antonio, Texas.  The complaint asserts U.S. Patent Nos. 8,102,144 (‘144 Patent) and 8,669,675 (‘675 Patent), each entitled “Power converter for a solar panel.”

The ‘144 Patent is directed to a solar power generation system including a DC-to-DC power converter configured and arranged to convert the raw power output for each solar module to a high voltage and low current output.

The ‘675 Patent is directed to a solar power generation system wherein each DC-to-DC power converter is configured and arranged to convert the solar module output power (SOP) for each solar module to a converted solar module output power (COP) having a converted output voltage (COV) that is higher than the SOV and a converted output current (COI) that is lower than the SOI.

The accused products are SolarEdge’s P Series Power Optimizers.

Water Meters

Flow Dynamics, LLC v. Green4All Energy Solutions Inc. et al.

Filed February 20, 2015 in federal court in Palm Beach, Florida, Flow Dynamics’ complaint accuses Green4All of infringing U.S. Patent No. 8,707,981 (‘981 Patent).

The ‘981 Patent is entitled “System for increasing the efficiency of a water meter” and directed to a system and an associated valve assembly adapted to increase the efficiency of an upstream water meter. The valve assembly removes entrained water bubbles from the water supply, increasing the density of the water running through the water meter. This ensures that the water meter is not inaccurately including entrained air as metered water so water readings are more accurate.

Flow Dynamics alleges that Green4All’s H2minusO system infringes the ‘981 Patent.

Gevo Gets Good GVR in Supreme Court Decision

February 24th, 2015

A previous post discussed one significant piece of the massive patent litigation between BP-DuPont joint venture Butamax and the advanced biofuels company Gevo.  The most recent prior thread of this case – which resembles a yo-yo in its narrative – was an appellate court win for Butamax.

Initially, the district court ruled for Gevo, granting its motion for summary judgment of non-infringement under the doctrine of equivalents of two Butamax patents – U.S. Patent Nos. 7,993,889 (’889 Patent) and  7,851,188 (’188 Patent).  The district also denied both parties’ motions on literal infringement and reached split decisions on validity of the patents.

Butamax appealed, and the Court of Appeals for the Federal Circuit then vacated both the grant of Gevo’s motion for summary judgement of non-infringement and the denial of Butamax’s motion for summary judgment.

Gevo petitioned to the U.S. Supreme Court to hear the case, and in a single, swift decision known as a GVR, the Supremes granted the petition, vacated the Federal Circuit decision, and remanded for further proceedings.  Grant-Vacate-Remand, hence GVR (read a blurb on the decision and GVR at the Patently-O blog here).

The Federal Circuit must now reconsider this case in light of the Supreme Court’s recent Teva Pharmaceuticals decision, which raised the standard for appellate review of district court factual determinations in patent claim construction rulings.

Previously, the Court of Appeals for the Federal Circuit used a “de novo” standard, which meant it could take a fresh look at the evidence on claim construction and make its own determination, which led to a high reversal rate.  After Teva, the Federal Circuit can reverse only where it finds “clear error” in the district court’s consideration of the facts in a claim construction decision.

So the yo-yo, in this thread of the patent war at least, swings back to Gevo with Butamax’s victory wiped out for the moment (see Gevo’s patent PR on the GVR decision here).

Clean Tech in Court: Green Patent Complaint Update

February 3rd, 2015

Several new green patent complaints were filed in late 2014 (late October, November, and December) in the areas of environmental remediation, LEDs, green dry cleaning solvents, and smart grid.

 

Environmental Remediation

Peroxychem LLC v. Innovative Environmental Technologies, Inc.

Peroxychem sued Innovative Environmental Technologies (IET) for patent infringement in the Eastern District of Pennsylvania.  Filed November 7, 2014, the complaint alleges that IET infringes U.S. Patent No. 7,785,038 (‘038 Patent).

The ‘038 Patent is entitled “Oxidation of organic compounds” and directed to methods and compositions for treating organic compounds present in soil and groundwater involving the use of a composition comprising a solid state, water soluble peroxygen compound and zero valent iron.

According to the complaint, IET’s activities at a site called Hexcel in Lodi, New Jersey infringe the ‘038 Patent.

 

Neochloris, Inc. v. Emerson Process Management Power & Water Solutions, Inc. et al.

Filed December 3, 2014 in the U.S. District Court for the Northern District of Illinois, Neochloris’s complaint alleges that Emerson infringes U.S. Patent No. 6,845,336 (‘336 Patent).

The ‘336 Patent is entitled “Water treatment monitoring system” and directed to a monitoring system to receive data from water sensors, analyze water quality conditions inputted by the sensors and predict effluent water quality and process upsets.  The monitoring system includes an artificial neural network module to determine solutions to actual and potential water quality and process upsets.

According to the complaint, Emerson’s Delta V System infringes the ‘336 Patent.

 

LEDs

Harvatek Corporation v. Cree, Inc.

Just weeks after Cree sued Harvatek for infringement of six patents relating to white light LED technology, Harvatek responded with a lawsuit of its own.  Harvatek filed a complaint December 5, 2014 in the Northern District of California, asserting one patent against Cree.

Entitled “Reflection-type light-emitting module with high heat-dissipating and high light-generating efficiency,” U.S. Patent No. 8,079,737 is directed to a reflection-type light-emitting module that includes a reflection-type lampshade unit with an open casing and a reflective structure formed on the open casing.

The accused products include the Cree LRP-28 series LED lamp.

 

Green Dry Cleaning Solvents

GreenEarth Cleaning, L.L.C. v. Personal Touch Valet Wholesale Bronx, Inc.

Kansas City-based GreenEarth Cleaning holds a number of patents directed to its environmentally friendly dry cleaning methods and solvents.  On December 23, 2014, GreenEarth sued Personal Touch Valet for alleged infringement of U.S. Patent No. 5,942,007 (‘007 Patent).

The ‘007 Patent is directed to methods and systems of dry cleaning articles comprising several steps including immersing the articles to be dry cleaned in a dry cleaning fluid including a cyclic siloxane composition.

The complaint, filed in the U.S. District Court for the Western District of Missouri, alleges that Personal Touch Valet is in breach of a license agreement with GreenEarth and is infringing the ‘007 Patent and several other related patents.

GreenEarth previously sued Glyndon Laundry for patent and trademark infringement.

 

Smart Grid

Endeavor MeshTech, Inc. v. Leviton Manufacturing Co., Inc.

Endeavor MeshTech, Inc. v. Eaton Corporation

On October 31, 2014, Endeavor MeshTech (a wholly-owned subsidiary of patent monetization firm Endeavor IP) filed two more patent infringement complaints.  One was filed against Leviton Manufacturing in the U.S. District Court for the District of Delaware (Endeavor v. Leviton), and the other against Eaton in the Northern District of Ohio (Endeavor v. Eaton).

The complaints accuse each defendant of infringing three patents in a family – U.S. Patent Nos. 7,379,981  8,700,749, and 8,855,019, each entitled “Wireless communication enabled meter and network.”  The patents-in-suit relate to a self-configuring wireless network including a number of vnodes and VGATES.
