Wind Turbine Litigation: Judge Orders Stay of GE v. Vestas

  • The patent litigation between GE and Vestas was put on hold pending the outcome of several challenges to the disputed patents brought at the Patent Trial and Appeal Board.
  • The patents at issue include both GE and Vestas patents directed to wind turbine technology, and specifically to ensuring safe and reliable connections between wind turbines and the power grid.
  • Based on scheduling at the PTAB, the patent litigation will likely be suspended for a minimum of six months and a maximum of eighteen months.

The U.S. District Court judge hearing a dispute over wind turbine patents between GE and Vestas put the case on hold last week, electing to await developments in a series of challenges brought against the patents at the Patent Trial and Appeal Board (PTAB). In an order signed June 7, 2018, Judge Andre Birotte Jr. indicated that the litigation is stayed (suspended) until the PTAB has issued Institution Decisions in each of the validity challenges filed by GE and Vestas (for a recap of those challenges, see our earlier posts regarding GE’s challenges against Vestas and Vestas’s challenges against GE).

GE v. Vestas Litigation Update: GE Moves to Sever Counterclaims, Vestas Brings Invalidity Challenge

  • GE asked a federal court to split its patent litigation with Vestas into two parts, which would allow the litigation to proceed with respect to GE’s claims against Vestas while delaying a trial on Vestas’ counterclaims against GE.
  • Vestas filed invalidity challenges at the Patent Trial and Appeal Board against the two GE patents asserted in the litigation.

The patent litigation between two titans of the wind turbine industry continues to heat up as the parties fight over the validity of each other’s patents and the scope of the dispute itself. GE and Vestas, reported to control more than 80% of the US wind turbine market, have been engaged in patent litigation since last summer. Recent developments in the case have the potential to greatly impact the number of claims heard at trial and the relative bargaining power between the parties. Continue reading “GE v. Vestas Litigation Update: GE Moves to Sever Counterclaims, Vestas Brings Invalidity Challenge”

Solar Tracking Patent Disputed: ArcelorMittal v. Array Technologies

  • ArcelorMittal has challenged the validity of a solar tracking patent owned by Array Technologies in a petition filed with the Patent Trial and Appeal Board
  • Array Technologies had previously brought infringement claims against a solar tracking company called Exosun. ArcelorMittal later bought assets from Exosun, which may have prompted ArcelorMittal’s challenge to the Array Technolgies patent.

International steel and manufacturing giant ArcelorMittal filed a petition in March at the Patent Trial and Appeal Board challenging the validity of a solar tracking patent owned by Array Technologies, Inc. If successful, ArcelorMittal’s challenge could result in the cancellation of a significant portion of Array Technologies’ U.S. Patent No. 8,459,249.

Design of Solar-Powered Lightbulbs at Issue in New Litigation

  • A pair of manufacturers are engaged in litigation over the specific design of a solar lightbulb.
  • Design patents are used to protect the appearance of a product rather than the product’s functionality.

The Gerson Companies, a home décor products importer based in Olathe, Kansas, has sued Quanxin Lighting and Electrical (USA) Inc. in federal court in Delaware last month for infringement of a design patent. The patent is directed to the design of a solar-powered lightbulb. In the lawsuit, Gerson has requested monetary damages and an injunction preventing Quanxin USA’s continued sale of the allegedly infringing products.

Federal Circuit Upholds Validity of Philips Patent on Dimmable LEDs

  • The Patent Trial and Appeal Board recently decided that a Philips patent on dimmable LED technology is valid despite a challenge from a competitor. That decision was later affirmed by the U.S. Court of Appeals for the Federal Circuit.
  • The patent at issue has been well-litigated, with Philips asserting the patent against numerous competitors in federal courts and at the U.S. International Trade Commission.

A patent directed to dimmable LED technology was upheld as valid in an appeal to the U.S. Court of Appeals for the Federal Circuit. The patent is owned by Philips Lighting North America Corporation, a subsidiary of Dutch consumer product giant Koninklijke Philips N.V. The Federal Circuit’s decision marks the unsuccessful conclusion of a challenge to the patent’s validity brought by a competitor of Philips Lighting called Wangs Alliance Corporation, which does business under the name WAC Lighting.

The Evolving Role of Microgrids

The latest hurricane season, which left millions without power for substantial periods of time, was yet another reminder of the urgent need to make America’s electrical grid more resilient. The increasing frequency and intensity of such storms is exposing the vulnerabilities of the aging electrical grid, i.e., the network of transmission and distribution lines often spanning long distances between power generation sources and population centers. These lines can be taken out of service by falling trees, flying debris, or extreme heat or cold, while their substations can be destroyed by flooding, leaving tens of thousands of customers without power at a time.

Microgrids, which provide more localized power generation and distribution, can play a vital role in providing resilience by islanding themselves from the rest of the grid during such outages while continuing to provide power to critical facilities. In addition to providing resiliency, microgrids have other potential benefits, such as reducing peak demands for the larger grid through optimization of resources, reducing carbon emissions through increased energy efficiency and the deployment of renewable energy resources, and acting as market participants in the organized wholesale electricity markets. These evolving roles for microgrids raise legal questions for state and federal regulatory authorities, which are racing to catch up with this technology to provide appropriate guidance and regulation.

GE Opens a Second Front in Patent Fight with Vestas

  • GE filed petitions on Friday to challenge the validity of a pair of Vestas patents at the Patent Trial and Appeal Board. Those patents were asserted by Vestas against GE in related patent litigation in federal court.
  • GE and Vestas are now likely to continue their patent fight in two forums: the federal court hearing patent infringement claims between the parties and the Patent Trial and Appeal Board hearing GE’s validity challenges to the Vestas patents.

General Electric Co. has challenged a pair of patents owned by Vestas Wind Systems A/S at the Patent Trial and Appeal Board. In petitions for inter partes review filed last Friday, GE alleges that the Vestas patents are invalid because they merely claim as inventions what was already known in the field of wind turbine technology. With the parties already engaged in litigation in U.S federal courts, GE’s move opens a second front in the ongoing patent fight with Vestas.

GE initially sued Vestas in July 2017, alleging that Vestas infringes GE’s U.S Patent No. 6,921,985. In November, GE expanded the lawsuit by adding another patent – GE’s U.S. Patent No. 7,629,705 – that GE asserted Vestas also infringes. Both of GE’s asserted patents are directed to technology for connecting wind turbines to power grids.

SemaConnect Wins Dismissal of ChargePoint’s Patent Lawsuit

  • A federal court dismissed claims of patent infringement brought by ChargePoint, Inc. against a rival in the EV charging station market, SemaConnect, Inc. The court found ChargePoint’s asserted patents to claim inventions that are ineligible for patent protection and thus unenforceable against SemaConnect.
  • ChargePoint has appealed the decision to the U.S Court of Appeals for the Federal Circuit, which will hear arguments between the parties.

Electric vehicle (EV) charging station provider SemaConnect Inc. won dismissal of a patent infringement lawsuit brought in federal court in Maryland. The lawsuit, brought by ChargePoint Inc., was thrown out after the court found that all four of ChargePoint’s asserted patents claim inventions that are ineligible for patent protection. Specifically, the court found that the patents claim nothing more than an “abstract idea” as their invention.

SemaConnect CEO Mahi Reddy called the result a “vindication of our effort to support open standards and interoperability of charging networks and stations.” He added that “this outcome is also a big win for the charging industry, the electric vehicle industry, and utilities.” Continue reading “SemaConnect Wins Dismissal of ChargePoint’s Patent Lawsuit”

Alstom Grid Appeals, Reverses Dominion Energy’s Patent Win

  • Alstom Grid successfully reversed a jury verdict finding that Alstom infringed a Dominion Energy patent directed to smart grid management technology.
  • The appeal was heard by the U.S. Court of Appeals for the Federal Circuit, which is the federal appeals court that takes all appeals of U.S. patent cases.

Alstom Grid LLC won an appeal at the Federal Circuit after last year suffering a patent trial loss to Dominion Energy, Inc. over smart grid management technology. In overturning the earlier jury verdict, the Federal Circuit stated that “no reasonable jury” could have found Alstom to infringe Dominion’s patent.

TESCO Moves Confidentiality Case to Pennsylvania

  • To hear a lawsuit between parties, a court must have personal jurisdiction over a defendant. Personal jurisdiction requires “minimum contacts” between a defendant and a state such that the defendant “should reasonably anticipate being haled into court there.”
  • Electric meter company TESCO used a lack of minimum contacts with the state of Tennessee to have litigation with plaintiff Technology for Energy Corporation moved to a more convenient court in Pennsylvania.

One of the first questions a defendant often asks when they’ve been sued is this: can I get the case moved to a more favorable court? Each court may have different administrative rules, different law to be applied in the case, and judges with different backgrounds. In these differences, litigants and their counsel often seek to find an advantage by trying to move cases among the various courts.
