Solar Tracking Patent Survives Challenge at Patent Trial and Appeal Board

  • A solar tracking patent owned by Array Technologies survived a challenged brought by ArcelorMittal before 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 Technologies patent.

A solar tracking patent owned by Array Technologies, Inc. was upheld as patentable in a final decision issued by the Patent Trial and Appeal Board earlier this month. The validity of the patent had been challenged by international steel and manufacturing giant ArcelorMittal in a petition filed with the Board in March 2018. After reviewing that petition and hearing arguments from both sides in the case, the Board has determined that the claimed invention of the solar tracking patent is both new and non-obvious over solar tracking technology at the time the invention was made. The Board therefore upheld the patentability of Array’s patent. Continue reading Solar Tracking Patent Survives Challenge at Patent Trial and Appeal Board

SunTrac Challenges Solar-Assisted Air Conditioner Patent

  • SunTrac Solar Manufacturing LLC has challenged at patent owned by DZSolar Ltd. that is directed to a solar-assisted temperature control system.
  • SunTrac alleges that the invention claimed by DZSolar was disclosed in another patent application at least 16 years before DZSolar filed its patent application. If SunTrac is successful in the challenge, the DZSolar patent would be canceled.

SunTrac Solar Manufacturing LLC, a producer of hybrid climate control systems based in Tempe, Arizona, filed a challenge last month against a patent owned by the U.K.-based DZSolar Ltd. SunTrac’s challenge was brought before the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, and alleges that the claimed invention of DZSolar’s U.S. Patent No. 9,267,713 is unpatentable because the invention was already well-known at the time DZSolar filed its patent application. In order to be eligible for a patent, a patent application must claim an invention that is a new and non-obvious improvement over existing technology at the time the patent application is filed.

Federal Court Litigation Between GE and Vestas Likely to Remain Stayed; Parties Continue to Battle at Patent Board

  • The patent infringement lawsuit being heard in federal court in Delaware between General Electric and Vestas Wind Systems A/S appears likely to remain on hold through late 2019 or early 2020.
  • GE and Vestas remain locked in a long-running patent battle over “Zero Voltage Ride Through” or “ZVRT” technology. Each party has brought challenges against the validity of the other party’s patents to the Patent Trial and Appeal Board, which is expected to hear those challenges over roughly the next 12 months.

The patent infringement case between rival wind turbine manufacturers GE and Vestas appears likely to remain on hold at least through late 2019 as the parties continue to battle over the validity of the asserted patents in separate cases before the Patent Trial and Appeal Board. GE and Vestas jointly filed a pair of status reports last month with the federal court in Delaware that is hearing the case, updating the court on the progress of those separate cases at the Patent Board. The court had earlier stayed the federal court litigation while awaiting decisions from the Patent Board on the validity of the GE and Vestas patents involved in the case.

Federal Circuit: Four ChargePoint Patents Assserted Against SemaConnect Are Invalid

  • The Federal Circuit upheld an earlier decision by a federal court in Maryland that found four ChargePoint patents to be invalid for claiming inventions that are not eligible for patent protection.
  • The Federal Circuit decision is a victory for electric vehicle charging station manufacturer SemaConnect, who was sued for allegedly infringing the four ChargePoint patents in December 2017.

The United States Court of Appeals for the Federal Circuit ruled last Thursday that four patents owned by ChargePoint, Inc., are invalid. The patents are directed to a networked electric vehicle charging station (EVCS) and were previously held invalid by a federal court in Maryland for claiming inventions that are ineligible for patent protection. ChargePoint had appealed that holding to the Federal Circuit. Continue reading Federal Circuit: Four ChargePoint Patents Assserted Against SemaConnect Are Invalid

The Coming EV Revolution

This post was co-authored by Brad Thompson and Nicole Candelori.

“Disruption” is a term that tends to be used casually when attempting to describe an industry or technological change on the horizon. Although the term may be overused in many contexts, it is hard to formulate a better word to describe the looming disruption that is certain to emanate from the increased adoption of electric vehicles (EVs).

There are numerous projections as to the anticipated volume and rate of movement away from internal combustion engines (ICEs) and towards EVs. According to one of those projections – a 2018 Bloomberg New Energy Finance report – global EV sales are expected to increase almost tenfold in just eight years: from 1.1 million in 2017 to 11 million in 2025, and later to 30 million in 2030. [1] Regardless of whether this forecast proves to be accurate on the timeline predicted, one trend line is undeniable: EVs are coming, and at some point relatively soon, the ICE will soon become a dying breed of vehicle transportation on the road.

The patents at issue are directed to a networked electric vehicle charging station (EVCS) and were previously held invalid by a federal court in Maryland for claiming inventions that are ineligible for patent protection. ChargePoint appealed that holding to the Federal Circuit. Continue reading Federal Circuit to Decide Validity of ChargePoint Patents

Vestas Challenge to Invalidate GE Wind Tech Patent is Denied

  • The Patent Trial and Appeal Board denied a challenge brought by Vestas Wind Systems A/S against a General Electric patent directed to technology for connecting wind turbines to the electric grid.
  • GE and Vestas remain locked in a long-running patent battle over “Zero Voltage Ride Through” or “ZVRT” technology. Each party has brought challenges against the validity of the other party’s patents to the Patent Trial and Appeal Board, which is expected to hear those challenges over roughly the next 12 months.

The Patent Trial and Appeal Board denied a challenge brought by Vestas Wind Systems A/S in the year-long patent feud with General Electric.  The Board, an adjudicatory body within the U.S. Patent and Trademark Office, determined that the challenge brought by Vestas against GE’s U.S. Patent No. 6,921,985 was nearly identical to an earlier challenge heard by the Patent Office.  Since re-hearing similar challenges is considered an inefficient use of the limited resources of the Patent Office, the Board decided to deny the Vestas challenge.
