Court Holds Grid Monitoring Patents Invalid; Collecting Info is Unpatentable Abstract Idea

August 30th, 2016

A prior post reported on the litigation between Electric Power Group (EPG) and Alstom Grid.

The lawsuit, filed in the Central District of California, alleged that Alstom’s “PhasorPoint” and “e-terravision” solutions infringed U.S. Patent Nos. 8,060,2597,233,843, and 8,401,710 (EPG Patents).

The EPG Patents relate to wide-area real-time performance monitoring systems for monitoring and assessing dynamic stability of an electric power grid.

More particularly, the patents describe and claim systems and methods for performing real-time performance monitoring of an electric power grid by collecting data from multiple data sources, analyzing the data, and displaying the results.

In an opinion issued earlier this month, the U.S. Court of Appeals for the Federal Circuit held the EPG Patents invalid under Section 101 of the Patent Act for failing the test for patent eligibility.  The decision affirmed the lower court’s grant of summary judgment.

Section 101 defines the subject matter eligible for patenting and, according to the Supreme Court’s 2014 decision in Alice Corp. v. CLS Bank Int’l, “contains an important implicit exception:  Laws of natural phenomena, and abstract ideas are not patentable” concepts.

Alice set out a two-stage Section 101 inquiry for determining patent eligibility.  Stage one asks whether a patent claim is directed to one of the three non-patent eligible concepts.

If so, at stage two, the court asks whether the particular elements of the claim add enough to “transform the nature of the claim into a patent-eligible application.”

According to the Federal Circuit, because the claims of the EPG Patents are directed to collecting and analyzing information and displaying certain results of the collection and analysis, they “fall into a familiar class of claims ‘directed to” a patent-ineligible concept.”

More particularly, information is an intangible, and collecting information is an abstract idea:

[W]e have treated collecting information, including when limited to particular content (which does not change its character as information), as within the realm of abstract ideas.

Furthermore, the court found the patents’ improvement of focusing on specific content to be collected and analyzed not sufficiently innovative:

The advance [the EPG Patents] purport to make is a process of gathering and analyzing information of a specified content, then displaying the results, and not any particular assertedly inventive technology for performing those functions.  They are therefore directed to an abstract idea.

Turning to stage two of the Alice framework, the Federal Circuit did not find anything added to the claims or any limitations that would remove them from the realm of abstract ideas and make them patent-eligible.  Limiting them to the power-grid monitoring space was not enough:

Most obviously, limiting the claims to the particular technological environment of power-grid monitoring is, without more, insufficient to transform them into patent-eligible applications of the abstract idea at their core.

Much of the content of the claims of the EPG Patents, the court observed, was “devoted to enumerating types of information and information sources available within the power-grid environment.”  Merely selecting that information does not “differentiate a process from ordinary mental processes.”

According to the court, the claims did not require any inventive set of components or methods, such as measurement devices or techniques, do not generate new data, and do not invoke any inventive programming.  They also do not require anything other than off-the-shelf, conventional computer network and display technology.

Thus, the court held that the EPG Patent claims “do not state an arguably inventive concept in the realm of application of the information-based abstract ideas” and are therefore invalid.

The Federal Circuit closed its opinion with some tough words from the district court about the EPG Patents that allude to a public policy rationale for invalidating the patents:

[R]ather than claiming “some specific way of enabling a computer to monitor data from multiple sources across an electric power grid,” some “particular implementation,” they “purport to monopolize every potential solution to the problem” – any way of effectively monitoring multiple sources on a power grid.

Some might say that alone is reason to invalidate the patents.

Master of its Domain: Infringement Verdict Could Mean Dominion Dominance in Advanced Metering

August 19th, 2016

Untitled

Once in a long while a green patent lawsuit comes along that has the potential to have a major impact on a clean technology sector.

A few that come to mind are GE’s litigation with Mitsubishi involving, among others, U.S. Patent No. 5,083,039, a seminal patent on variable speed wind technology, Paice’s epic battle with Toyota over the hybrid vehicle technology used in the Prius, and the biofuels patent litigation between BP-DuPont joint venture Butamax and the advanced biofuels company Gevo.

We may have witnessed another one this summer, with the announcement last month by Dominion Voltage, Inc. (Dominion) that a jury found Alstom Grid infringed a Dominion patent relating to voltage reduction in advanced metering infrastructure.

Dominion filed an infringement complaint against Alstom Grid in January 2015 in the U.S. District Court for the Eastern District of Pennsylvania.

The asserted patents were U.S. Patent Nos. 8,577,510 and 8,437,883 (‘883 Patent), related patents each entitled “Voltage conservation using advanced metering infrastructure and substation centralized voltage control.”

The patents, one a continuation of the other, are directed to voltage control and energy conservation systems where a plurality of sensors sense voltages of the supplied electric power at distribution locations and generate measurement data based on the sensed voltages.

A voltage controller generates an energy delivery parameter based on a comparison of the measurement data received from the sensors to a controller target voltage band, and a voltage adjusting device adjusts a voltage of the electric power supplied at the supply point based on the energy delivery parameter.

If that concept seems broad to you, it is, and the folks at Greentech Media thought so too.  In this piece reporting on the lawsuit, GTM said the asserted Dominion patents “appear to hold pretty broad claim over the very idea of using distributed sensors for grid voltage management.”

According to GTM, the patented technology is embodied in Dominion’s commercial products and is pervasive in the smart meter industry today:

That’s the technology behind DVI’s EDGE control platform, now in use by utilities across the country, and using smart meters and networks from a list of vendor partners including Silver Spring Networks, Elster and Landis+Gyr.

And now at least one of the major commercial users of the technology has been found to infringe of the patents.  According to the Dominion press release, the jury in the lawsuit returned a verdict of infringement, finding the ‘883 patent valid and infringed by Alstom Grid (now owned by GE).

The jury also found that Alstom “induced infringement through the installation of its distribution management system at a customer location.”

Dominion is likely to seek an injunction to stop Alstom Grid from installing and using the infringing products.  However, these cases more often result in a license negotiated by the parties including some sort of royalty payment.

In any event, Dominion is now in a very strong position in the smart meter-enabled grid voltage control space.  According to GTM, which covered the jury verdict here, the company is the U.S. leader in this market and now “has a jury verdict to protect the technology behind that market dominance.”

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.

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.
