Vestas Files New Challenge Against GE Wind Turbine Patent

  • After filing a first challenge against GE’s U.S. Patent No. 6,921, 985 in May, Vestas has filed a second challenge in August to expand its attack on that patent. GE had previously asserted the ’985 Patent against Vestas in a federal patent infringement lawsuit.

Last month Vestas Wind added yet another proceeding to its year-long patent battle against General Electric Company, filing a new challenge against GE’s U.S. Patent No. 6,921,985 at the Patent Trial and Appeal Board. Vestas had already filed one challenge against the ’985 Patent in May, and appears to have filed a second challenge to attack additional claims of the ’985 Patent.

GE, Vestas Battling in a Technological Field They Dominate

  • GE and Vestas are now one year into patent litigation that has the potential to impact the U.S. wind turbine market. The parties reportedly control more than 80% of the market between them.
  • The patents at issue claim inventions in the field of controlling wind turbine generators. GE and Vestas are the preeminent patent owners in this field.

This week marks one year since GE filed a patent lawsuit against its main rival in the U.S. wind turbine industry, the Danish company Vestas A/S. In the past year, GE has modified its patent infringement allegations; Vestas has denied infringement, alleged inequitable conduct by GE when obtaining the patents, and counter-sued GE for infringing Vestas’ patents; and both parties have filed challenges to each other’s asserted patents with the Patent Trial and Appeal Board (see here and here). The litigation in federal court was also recently put on hold to await the outcome of those challenges at the PTAB. Continue reading GE, Vestas Battling in a Technological Field They Dominate

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).

Varentec Dodges Gridco Requests for Inter Partes Review

  • An inter partes review is an administrative proceeding that asks the U.S. Patent and Trademark Office to invalidate a U.S. Patent. These reviews are commonly used by patent litigation defendants to challenge the validity at the U.S. Patent and Trademark Office of patent claims that have been asserted against them in a U.S. District Court.
  • After Varentec sued Gridco for patent infringement, Gridco requested inter partes reviews for the asserted patents. However, Gridco’s requests were denied.

Grid management solutions company Varentec, Inc., dodged a pair of requests by rival Gridco, Inc. to invalidate Varentec’s U.S. patents this week. Gridco had challenged Varentec’s patents at the Patent Trial and Appeal Board (PTAB), an administrative tribunal within the U.S. Patent and Trademark Office (USPTO) that hears claims against the validity of U.S. patents.   The PTAB denied Gridco’s requests for review of U.S. Patent Nos. 9,014,867 and 9,293,922. These related patents are owned by the Santa Clara-based Varentec and are directed to optimizing power delivery to consumers on an electrical grid with significant distributed generation.

Itron Earns Review of Smart Meter Patent

  • An inter partes review is an administrative proceeding that asks the U.S. Patent and Trademark Office to invalidate a U.S. Patent. These reviews are commonly used by patent litigation defendants in an attempt to invalidate patent claims that have been asserted against them.
  • Itron requested inter partes review of a patent owned and asserted by Smart Meter Technologies. Itron’s request was granted.

The Patent Trial and Appeal Board has agreed to review the validity of a smart utility meter patent owned by Smart Meter Technologies, Inc. (“SMT”). The validity challenge was filed by Itron, Inc., a manufacturer of smart utility meters and provider of grid monitoring and control technologies. In a decision dated October 11, 2017, the Board found that Itron had brought forth sufficient evidence of the patent’s invalidity to warrant a review proceeding.
