Keeping the Aisles Clear: Envision’s Parking Lot Solar Chargers Got Tracking!

February 9th, 2016

Envision logo

Envision Solar (Envision) is a San Diego-based company that makes solar parking structures that can be used to charge electric vehicles, support outdoor digital advertising, and enhance energy security.  What makes Envision’s products unique is that unlike most parking lot solar-powered vehicle charging stations, most of the company’s systems have the ability to track the movement of the sun.

According to Envision’s President and CEO Desmond Wheatley, 90% of Envision’s deployments have tracking capability.  Why tracking?  He echoed my thoughts exactly:  because it’s “cool.”

Also, parking lots are “hyper-restrained” in geography so a solar charger needs to maximize energy density in a very small space.  Incorporating tracking helps in that regard.

Envision’s two major product offerings are the Solar Tree® and the EV ARC™.  The company owns at least seven U.S. patents and pending applications covering various aspects of the technology in these products.

U.S. Patent No. 7,705,277 (‘277 Patent), issued in 2010, covers Envision’s original design.  Entitled “Sun tracking solar panels,” the ‘277 Patent is directed to a system for maximizing solar energy utilization by moving a solar panel to track movement of the sun from sunrise to sunset.  Movements of the solar panel are accomplished daily in accordance with a programmed schedule of consecutive cycles.

A subsequent patent issued in early 2014 is directed to a refined design better suited for solar tracking in a parking lot.  The system covered by U.S. Patent No. 8,648,551 (‘551 Patent) is significant, Wheatley said, because instead of the tracker causing the solar panel to swing in to the drive aisle, it instead bows.

According to the ‘551 Patent, the rotation of a cylindrical knuckle in the tracking system “allow[s] the solar panel to continuously reorient while maintaining a substantially stationary footprint.”

Wheatley told me the company’s most important intellectual property is that around the features of the EV ARC™.

Wheatley mentioned several advantageous features of the EV Arc.  First and foremost is its autonomy, i.e., it is not connected to the utility grid.  Some of the structural features are also important, including the ability for the thin base plate to support heavy vehicles and the high-traction material of the base plate, which allows it to remain stationary.

U.S. Patent No. 9,209,648, issued in November 2015, is entitled “Self-contained renewable battery charger” and is directed to a charging system (10) comprising a portable unit (12) that includes a moveable docking pad (16) having a base (18) and compartment (20) for holding a storage battery (18).

 

648 FIG 1

The portable unit (12) includes a column (24) having a first end (26) mounted onto the docking pad (16) and a second end (28).  A solar array (30) is affixed to the second end (28) of the column (24).  The unit has a structural canopy with a beam (32) and cross members (34) attached to the column (24) to support the photovoltaic modules of the solar array (30).

The company also has IP around the mobility and installation of its systems, including a specialized trailer and hydraulic ram, ARC™ Mobility, for transportation and deployment purposes.

Wheatley and Envision are very aware of the importance of patent protection in the U.S. and beyond.  The company’s patents, he said, “prevent smaller competitors from copying” their technology.  They also might stop larger customers from buying pirated products.  In general, a strong IP portfolio increases the company’s value in the investor community.

With investments of about $200 billion on EV charging, the company sees China as an important market and has filed patent applications there.  Wheatley told me that Chinese patents allow Envision to bring powerful partners aboard in China to protect the company’s business ventures there.

Envision Solar continues to innovate and isn’t stopping at car charging; they’re working on EV ARC™ eBike and eMotorcycle charging as well.  Many more patent applications will certainly follow.

Paice Licenses Hybrid Vehicle Patents to More Big Automakers

February 2nd, 2016

l_paice

In another big success for Paice, the hybrid vehicle technology company recently reached an agreement to license all of its tech to Hyundai and Kia.

This comes after a Baltimore jury found that the Korean automakers owed Paice $28.9 million in damages for infringing three patents relating to hybrid electric vehicles: U.S. Patent Nos. 7,237,634, 7,104,347, and 7,559,388.  All three patents are entitled “Hybrid vehicles” .

Paice has been an extremely successful non-practicing entity, using patent litigation in the federal courts and the U.S. International Trade Commission to bring major automakers to the negotiating table.

In 2010 the company settled major patent litigation with Toyota over the Prius and other hybrid models when the Japanese automaker licensed all of Paice’s patents.  Also that year, Paice and Ford became embroiled in patent litigation over hybrid vehicles.

According to the company’s press release about the Kia/Hyundai deal:

Paice has now licensed all or part of its hybrid vehicle technology portfolio to Toyota, Hyundai/Kia, and Ford – three of the world’s six largest automakers.  These three companies currently account for 90% of all hybrid vehicle sales in the United States.

Does all this litigation and licensing make Paice one of the oft-maligned “patent trolls?”  I think not.

The company should not be put in that category for a couple of reasons.  First, the founder of the company and inventor of the technology, Alex Severinsky, is a true innovator and pioneer, having invented much of Paice’s technology at least as early if not earlier than the large automakers.

Most of the patent assertion entities we think of as trolls are not innovators, but instead buy patents to assert in litigation and offer to license.

Second, Paice made genuine efforts at ex ante licensing.  That is, the company approached Toyota with offers to license its technology before any hybrid vehicles were ever sold.

This is in contrast to the business model of acquiring and asserting patents, with licensing offers, after the allegedly infringing products have been manufactured and racked up lots of sales (ex post licensing).

Paice’s success is not a surprise when one understands the power of its patents.  A 2010 report by a patent analytics firm called Ambercite analyzed 58,000 hybrid car patents and their interrelationships using network patent analysis methodology and found Paice’s portfolio to be the strongest, better than all major car manufacturers’ hybrid car patents.

Oscilla’s Power Bars Generate Energy from Waves

December 1st, 2015

Oscilla logo

I recently read an interesting article about Oscilla Power, a Seattle-based company that makes wave power generators.

Oscilla’s wave energy harvesters are based on a phenomenon called magnetostriction, a property of some ferromagnetic materials to change their shape slightly in the presence of a magnetic field.

However, Oscilla applies this process in reverse – called reverse magnetostriction – by applying stresses or strains to the materials so their magnetic characteristics change.  When coupled with a generator that has permanent magnets and wire coils, the process generates electricity.

Oscilla owns a number of patents and pending applications covering its technology, including two related U.S. Patent Nos. 7,816,797, and 7,964,977, entitled “Method and device for harvesting energy from ocean waves.”

These patents are directed to a device (100) for harvesting energy from the oscillations of ocean waves (102).  The core modules of the device (100) include at least one buoy (104) attached to magnetorestrictive elements (106) via tethers (110).

797 FIG. 1

The magnetorestrictive elements (106) are anchored to the seafloor or to another rigid body using anchors or weights (108).

According to the Economist piece, the magnetorestrictive elements are bars made from a strongly magnetic alloy of iron and aluminum.  These bars need be compressed only very slightly (one part in 10,000) to generate electricity.

Even such a tiny compression takes a large force when the bar is made of solid metal, but ocean waves have sufficient power to generate the required force and do so by oscillation.  Oscilla’s generators have two large objects connected by cables:

Oscilla Pic

A buoy floating on the surface of the ocean contains the generating apparatus of alloy bars, magnets and coils, as well as sets of hydraulic rams which can squeeze the bars.  The cables connect the buoy to a heave plate maintained in a stationary position.

As the buoy rises and falls with the waves at the surface and the heave plate stays still, the tension on the cables increases and decreases.  The changing tension drives the rams and produces electricity.

Because the generators operate on changing tension, they don’t need to employ lot of moving parts and should therefore be more reliable than conventional wave power generators.

After a successful trial of a four-meter prototype last year, Oscilla hopes to build a full-scale device by 2018.

Clean Tech in Court: Green Patent Complaint Update

November 19th, 2015

Several new green patent complaints were filed in September and October in the areas of LEDs, smart grid, smart meters and wastewater handling.

 

Smart Grid

JSDQ Mesh Technologies LLC v. Silver Springs, Inc. and Pepco Holdings, Inc.

JSDQ filed a patent infringement lawsuit on September 10, 2015 in the U.S. District Court for the District of Delaware.

This complaint accuses Silver Springs and Pepco of infringing three U.S. Patents Nos. 7,286,828 entitled “Method of Call Routing and Connection,” RE43,675 entitled “Wireless Radio Routing System,” and RE44,607 entitled, “Wireless Mesh Routing Method.”

The technology involved in the suit includes Silver Springs’ Smart Grid Mesh Network solutions, which the complaint alleges includes a wireless routing system and an Aerohive routing system used in conjunction with directional radio signals.

The complaint alleges Pepco is infringing the patents through its use of Silver Springs’ Smart Grid Mesh Network and associated products and services.

 

Smart Meters

 Transdata, Inc. v. Landis+Gyr, Inc. and Landis+Gyr Technology, Inc.

Transdata, Inc. v. Itron, Inc.

Transdata, Inc. v. General Electric Company and GE Energy Management Services, Inc.

On September 11, 2015, TransData filed three separate complaints in federal court in Tyler, Texas.

Each of the three complaints corresponds to a different defendant(s) (see the complaints here, here, and here), but each complaint asserts the same three patents.  These complaints follow a long list of consolidated “smart meter” cases, and in each complaint, Transdata notes that the defendant(s) indemnified and/or defended other defendant(s) in the earlier consolidated cases.

Two of the asserted patents, U.S. Patent Nos. 6,181,294 (‘294 Patent)and 6,462,713 (‘713 Patent) are related and entitled “Antenna for Electric Meter and Manufacture Thereof.”  The third patent, U.S. Patent No. 6,903,699, entitled “Wireless Communication Device for Electric Meter and Method of Manufacture Thereof,” is a continuation-in-part of ‘713 and continuation of ‘294.

These patents describe an electric meter capable of bi-directional communication over a wireless network.  The meter is equipped with wireless communication circuitry and an antenna allowing the meter to wirelessly send usage data to a remote location and wirelessly, receive operational instructions from the remote location.

For a more detailed discussion of the patented meter technology and discussion of earlier case, see our previous post here.

Numerous industrial and residential electric meters made by the defendants are at issue in these cases.

The Landis+Gyr products include residential meters containing the Landis+Gyr Gridstream RF Mesh Residential Endpoint; industrial and commercial meters containing Landis+Gyr Gridstream RF Mesh Commercial  and Industrial Endpoint; and meters with the AMI communication modules and antenna.

The Itron and General Electric meters include various residential and industrial meters equipped with under-the-glass wireless communication modules and meters with the AMI communication modules and antenna.

 

LEDs

Global Tech LED, LLC. V. Every Watt Matters, LLC and DRK Enterprises, Inc.

Global Tech LED, LLC V. Hilumnz International Corp., Hilumnz, LLC and Hilumnz USA, LLC

Global Tech LED filed a complaint against Every Watt Matters and DRK (“EWM”) on September 14, 2015 and a complaint against Hilumnz on September 15, 2015.

Both complaints were filed in the U.S. District Court for the Southern District of Florida and allege the defendant(s) infringed U.S. Patent No. 9,091,424, entitled “LED Light Bulb.”

The patent pertains to an LED device that can replace or retrofit a light bulb in an electrical socket.  The LED device has a screw connector for screwing into a light bulb socket.  A bracket connects the screw portion to the housing, which holds one or more LEDs.  The housing can rotate to direct the light from the LED and contains an electrically powered cooling fan to dissipate heat generated by LED.

Both complaints allege EWM and Hilumnz offer for sale infringing LED lamp products.  The Hilumnz complaint also alleges that Hilumnz offers for sale various Retrofit Kits.

 

Wastewater Handling

Liberty Pumps Inc. v. Franklin Electric Co., Inc.

On October 23, 2015, Liberty Pumps Inc. (“Liberty”) filed a complaint in the U.S. District Court for the Western District of New York.  The complaint alleges Franklin Electric Co. Inc. (Franklin) is infringing U.S. Patent Nos. 8,523,532 (‘532 Patent) and 8,888,465 (‘465 Patent) entitled, “Sewage Handling System, Cover and Controls.”

The ‘532 and ‘465 Patents describe a basin/pump assembly for moving liquids such as sewage.  If a bathroom is lower than a household sewer effluent pipe, this assembly would pump the bathroom wastewater to the level of sewer effluent pipe.

The assembly has a basin with a bottom, sides and a hanging feature formed into the basin.  The hanging feature has a hanging portion with a level switch.  A pump is disposed in the basin.  Also, the basin may have a cover assembly that can be fastened to the open top of the basin.

Supremes’ Alice Ruling Drowns Water Treatment Patent

November 10th, 2015

A Green Patent Complaint Update post reported on the patent infringement suit between Neochloris and Emerson Process Management Power & Water Solutions.  Citgo was also named as a defendant.

In the lawsuit, Neochloris accused Emerson and Citgo of infringing 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.

The defendants jointly moved for summary judgment that the ‘336 Patent is invalid because it covers non-patentable subject matter under 35 U.S.C. § 101.  Section 101 of U.S. patent law delineates the broad categories of subject matter deemed eligible for patent protection.

These comprise “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof…”

Generally excluded from eligibility are laws of nature, natural phenomena, and abstract ideas.  Patentable subject matter has been in flux for the last several years and recent case law has rendered previously eligible areas such as business methods and software very difficult to patent.

In a recent decision, Judge Edmond E. Chang of the U.S. District Court for the Northern District of Illinois granted the summary judgment motion, ruling that the ‘336 Patent protects an unpatentable abstract idea.

The court’s decision began with a summary of the asserted claims of the ‘336 Patent, stating that they describe a method for:

  1. collecting data at a water treatment plant;
  2. sending the data over an internet connection to a computer;
  3. monitoring and analyzing the data with an ordinary computer and software; and
  4. alerting the facility of any abnormalities.

The U.S. Supreme Court’s 2014 Alice v. CLS Bank decision laid out the current analysis for determining patentable subject matter under Section 101.  The first question is whether the claims are “directed to a patent ineligible concept” on their face.  If so, the second question is whether the claims nonetheless contain an “inventive concept” that can make the concept a patent eligible invention.

Judge Chang concluded that the claims of the ‘336 Patent cover an abstract idea:

[A]t bottom, the claims cover the general process of observing, analyzing, monitoring, and alerting that can be done entirely by the human mind and by using pen and paper….the Federal Circuit has determined that collecting and processing data is an abstract idea.

The court went on to find that the claims do not contain any inventive concept.  Neochloris argued that the claims have three patent-eligible inventive features:  the use of computers and software, the ability to predict future failure events, and the ability to reduce human error.

However, the court found all of these functions to be conventional and that the claims of the ‘336 Patent merely recite basic computer functions:

[T]he ‘336 patent employs any “monitoring computer” and any “software” to perform basic computer functions.  The computer and software simply make routine calculations to monitor and analyze water data.  The claims are not limited to any particular software or hardware, and this generic technology has no special capabilities that “improve the functioning of the computer itself” or “effect an improvement in any other technology or technical field.”  Because the addition of a computer and software in the ‘336 patent “does no more than require a generic computer to perform generic computer functions,” this generic technology does not save the ‘336 patent.

Similarly, the ability of the patented system to predict future failure events, even if it is better than could be done by a human operator, is not inventive:

There is no inventive concept when a computer just replicates what a person can do, only more quickly and accurately.

Finally, the court found that reducing human error “only describes the generic ability of a computer to work more accurately and does not make the claim inventive.”

With software so integral to so many environmental and other green technologies, this surely is not the last we’ll see of Alice impacting green patents.

Remembering Innovator Stanley Klein

November 4th, 2015

The late Dr. Stanley Klein was a well-known engineer and innovator in a number of fields, including utilities, smart grid, and power systems design and development.

Dr. Klein is the named inventor on U.S. Patent No. 8,731,732, entitled “Methods and system to manage variability in production of renewable energy” (‘732 Patent).  Unfortunately, Dr. Klein passed away while the ‘732 Patent was pending.

The ‘732 Patent is directed to systems and methods of controlling loads coupled to an electric grid to manage variability in production of renewable energy.

The loads may be controlled in response to an indication of balance between available power and loads, in response to new loads, or grid disconnections, and may be controlled repeatedly over time to adjust a sum load in response to changes in balance between available power and loads, new loads, and grid disconnections.

I recently spoke with Dr. Klein’s daughter and son-in-law, Mitch Billian, who together prosecuted the application after his death and obtained the granted patent on his behalf.

Mr. Billian told me the ‘732 Patent is a significant innovation in controlling loads.  The patent includes a “detailed consideration of the communications and networking required to achieve the desired control, including the communication protocol exchanges between the control centers and the controlled loads.”

The patent also discusses the role of aggregators in load control, providing an “identification of the role and facilities of aggregators in combining control of such controllable loads to supply ancillary services to the grid,” Billian said.

FIG. 4 of the ‘732 Patent illustrates a load control center (416) which aggregates load information from multiple loads:

FIG. 4

In environment (400) load control center (416) receives load parameters from controllable loads (404) through load control network (406) to calculate load settings for one or more of the controllable loads (404) in view of the aggregated indications of available power and to communicate the load settings to the corresponding controllable loads (404) through load control network (406).

The impact of the patented technology on renewable energy use could be substantial as it allows “control of large numbers of existing and future residential, commercial, or industrial loads to help in achieving real power balancing control to compensate for the variability of wind power and other renewable generation,” Billian said.

An excerpt form Dr. Klein’s bio shows some of the diverse areas in which he made an impact during his life:

Dr. Stanley Klein, a Managing Principal of OSECS, represents OSECS in Smart Grid efforts and
in numerous other standards activities. He is active in SGIP activities including the Cyber
Security Working Group (CSWG) and several of its subgroups the Transmission and
Distribution Domain Experts Working Group (T&D DEWG), Priority Action Plans PAP-11 (on
Common Object Models for Electric Transportation), the Vehicle-to-Grid DEWG, PAP-14 (on
T&D Model Mapping), and PAP-16 (on Wind Plant Communications). He is also a member of
IEC TC 57 WG-15 on cybersecurity for the IEC standards, was a member of the IEC task group
that prepared IEC-61400-25-4 Annex A, has participated in a number of IEEE standards efforts
as a member of either a working group or a ballot pool, and is a member of the NERC Control
System Security Working Group (that prepares relevant NERC guidelines).

The world could use more brilliant innovators like Dr. Klein.

Big Win for Paice as Jury Finds Hyundai and Kia Owe $28.9 Million

October 20th, 2015

l_paice

Back in 2012, hybrid vechicle technology company Paice filed a lawsuit against Hyundai and Kia in federal court in Baltimore accusing the Korean automakers of infringing three of its patents.

The patents-in-suit were U.S. Patent Nos. 7,237,634, 7,104,347, and 7,559,388.  All three patents are entitled “Hybrid vehicles” and cover hybrid electric vehicles utilizing an internal combustion engine with series parallel electric motors, regenerative braking, and control circuitry.

The Paice technology is called the Hyperdrive System and provides seamless switching between power from an electric motor and an internal combustion engine.

Recently, a Maryland federal jury returned a big verdict for Paice, deciding that Hyundai and Kia owe $28.9 million in damages for patent infringement.  The jury found that all of the asserted claims of the patents were valid and willfully infringed (see the report here on Autoblog and by Bloomberg news here).

The trial lasted eight days, but the jury needed just one day of deliberations to reach a verdict.

According to Paice’s press release, the $28.9 million sum represents a payment of $200 for each infringing hybrid vehicle sold by the defendants through June 30, 2015.  The cars at issue were the Hyundai Sonata Hybrid and the Kia Optima Hybrid.

Paice has successfully enforced its patents before, most notably licensing its hybrid technology to Toyota, which signed a global licensing deal in 2010 covering all of Paice’s technology.

Hyundai and Kia are likely to appeal the decision.

Book Review: The Globalization of Clean Energy Technology by Kelly Sims Gallagher

October 6th, 2015

Gallagher book

The Globalization of Clean Energy Technology:  Lessons from China is a thoroughly researched and well-written book and an important contribution to the subject of clean tech innovation.

Five years in the making, Kelly Sims Gallagher’s book uses case studies of four clean energy industries (gas turbines, solar PV, coal gasification, and advanced batteries) in China to learn lessons about international technology transfer.

To guide her research, Gallagher asked these questions:

Which barriers most inhibit the global diffusion of cleaner and more efficient energy technologies?

Which incentives or conditions are necessary to motivate the global diffusion of these technologies?

Through dozens of interviews with individuals in firms, academic experts, and government officials, as well as focus groups, patent analysis, and comparative policy analysis, the book does much to uncover which commercial and policy factors have positive or negative effects on the clean energy industries examined.

I particularly like the organization of the book.  After an introduction and a chapter on China’s energy and environmental policies and innovation system, Chapter 3 presents the case studies as “complete stories” and introduces barriers and incentives to global diffusion of clean technologies.

The case studies represented both “successful” (solar PV) and “failed” (gas turbines) technology transfer and some mixed results (advanced batteries for vehicles and coal gasification).

Subsequent chapters provide detailed analysis of three of the most critical actual or perceived barriers – policy, intellectual property, and cost/finance.

The conclusions Gallagher draws are that national market-formation policies and access to capital are the most important factors needed for global diffusion of clean technologies.

Intellectual property is not generally found to be an impediment to clean tech innovation and transfer:

One set of barriers/incentives that this research does not find significant for the cross-border diffusion of cleaner energy technologies is access to or infringement of intellectual property.

However, there have been some refusals to license, including Toyota HEV patents:

The Chinese have not been able to obtain licenses from Toyota for hybrid-electric technology, and they further think there is no room for Chinese innovation because the Japanese firms have defensively patented the entire space.

But even this may be a blessing in disguise as the Chinese may be leapfrogging to EVs.

One refreshing thing about this book is that Gallagher has no apparent agenda (a marked departure from some literature on the subject).  She writes in the mold of some of the economists who have studied the effects of patents on clean tech such as John H. Barton.  The book is empirically focused; Gallagher wants to find the facts and get to the bottom of it.

And get to the bottom of it Gallagher does.  She finds “widespread agreement that the most important incentive is national-level, market-formation policies.”

The Chinese and foreign experts she interviewed agree that such incentives have encouraged cross-border transfer of the four clean technologies studied – policies including clear targets over time, lack of significant barriers to trade and foreign direct investment, strong innovation policy, stable market-formation policy, and strong export promotion policy.

An extra feature, and another reason to buy this book, is the nearly comprehensive list of case studies on clean tech transfer in Appendix B.

In conclusion, Gallagher’s book is a major contribution to the clean tech innovation literature.  She explains the nature of the contribution concisely:

One of this book’s contributions is to clarify which barriers and incentives for the global diffusion of cleaner energy technologies are most important in the Chinese context, and, ideally, more generally.

Clean Tech in Court: Green Patent Complaint (and Settlement) Update

September 22nd, 2015

Several new green patent complaints were filed in July and August in the areas of LEDs, smart grid, and water meters.

But before we get to that, a significant green patent case settled during this period.  Colorado-based Gevo and BP-DuPont joint venture Butamax announced that they entered into worldwide patent cross-license and settlement agreements.

The deal ends a massive patent dispute that began back in early 2011 and grew to comprise at least 17 lawsuits and 14 patents relating to methods of producing biobutanol.

The agreement grants both parties patent licenses to all fields for isobutanol and includes a combination of royalty-bearing and royalty-free fields for both parties.  According to this piece from Biofuels Digest, it seems the core of the deal is that Butamax will take the lead in the on-road gasoline market and Gevo gets the jet fuel market.

The litigation was notable both for its size and as the first foray of big oil into biofuels patent lawsuits.

 

LEDs

Feit Electric Company, Inc. v. Cree, Inc.

After Cree sued Feit for alleged infringement of 10 patents back in January, Feit fired back with this lawsuit filed July 7, 2015 in U.S. District Court for the Middle District of North Carolina.

The complaint accuses Cree of infringing two related U.S. Patent Nos. 8,408,748 and 9,016,901, both entitled “LED lamp replacement of low power incandescent lamp” (LED Lamp Patents).

The LED Lamp Patents are directed to LED light bulbs for replacing incandescents.  The LED lamp has an elevated light source positioned above a screw-type base and two groups of LEDs connected in series with each LED mounted proximate a heat sink.

The accused products are Cree’s 4Flow LED lamps.

 

Koninklijke Philips N.V. et al. v. Amerlux LLC et al.

Philips has filed another patent infringement lawsuit, asserting six LED lighting patents against New Jersey lighting company Amerlux.  The complaint was filed August 5, 2015 in the U.S. District Court for the District of Massachusetts.

The patents-in-suit are:

U.S. Patent No. 6,094,014, entitled “Circuit arrangement, and signaling light provided with the circuit arrangement”

U.S. Patent No. 6,250,774, entitled “Luminaire”

U.S. Patent No. 6,577,512, entitled “Power supply for LEDs”

U.S. Patent No. 7,038,399, entitled “Methods and apparatus for providing power to lighting devices”

U.S. Patent No. 7,262,559, entitled “LEDs driver”

U.S. Patent No. 8,220,958, entitled “Light-beam shaper”

Philips alleges that a host of Amerlux products infringe one or more of the asserted patents, including accent display lighting products, task lighting products, wall wash and grazer lighting products, shelf lighting products, downlights, pendants, outdoor lighting products, and other luminaire-type lighting products.

 

Smart Grid

Endeavor MeshTech, Inc. v. Redpine Signals, Inc.

Endeavor MeshTech, Inc. v. Atmel Corporation

Endeavor MeshTech (a wholly-owned subsidiary of patent monetization firm Endeavor IP) continued its patent enforcement campaign, filing two more lawsuits in July and August.

The first was filed against Redpine in U.S. District Court for the Southern District of New York on July 1, 2015 (Endeavor Meshtech v. Redpine), the second against Atmel in U.S. District Court for the District of Colorado on July 6, 2015 (Endeavor Meshtech v. ATMEL).

The two complaints accuse Redpine and Atmel, respectively, of infringing three patents in a family – U.S. Patent Nos. 7,379,981 (‘981 Patent),  8,700,749 (‘749 Patent), and 8,855,019 (‘019 Patent), 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.

The accused products are Redpine’s n-Link, Connect-io-n, WiSeConnect, M2MCombo, SmartCombo, NetCombo and WinergyNet products and Atmel’s products sold under the brand names ZigBit, SmartConnect, BitCloud, and SMART.

 

Regen Energy Inc. v. eCurv Inc. 

On August 19, 2015 Regen Energy, a Canadian corporation with operations in San Marcos, California, sued Massachusetts-based eCurv for alleged infringement of U.S. Patent Nos. 8,918,223 (‘223 Patent) and 9,110,647 (‘647 Patent).

The ‘223 and ‘647 Patents are related patents entitled, respectively “Apparatus for managing an energy consuming load” and “Method and apparatus for managing an energy consuming load.”  They are directed to energy management systems and methods that generate load state data from energy consuming loads, make enablement state decisions for the loads using the load state data, and implement the enablement state decisions.

Filed in U.S. District Court for the Southern District of California, the complaint alleges that eCurv’s QPAC line of energy management software and related products infringe the ‘223 and ‘647 Patents.

 

Water Meters

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

In this action for tortious interference, unfair competition and declaratory judgment, Chicago-based Green4All requests that the court declare Flow Dynamics’ U.S. Patent No. 8,707,981 (‘981 Patent) invalid.

The ‘981 Patent is entitled “System for increasing the efficiency of a water meter” and directed to a valve assembly that increases the efficiency of an upstream water meter by removing entrained water bubbles from the water supply.

Filed August 5, 2015 in U.S. District Court for the Northern District of Illinois, the complaint alleges that Flow Dynamics’ prior filed patent infringement suit against Green4All (reported here) is without merit and the ‘981 Patent should be declared not infringed and invalid.
