Patent Status

U.S. Patent No. 8,689,709, 8,961,629, 9,181,502, and 9,150,800

Introduction

The U.S. Department of Energy (DOE) Hydrocarbons and Geothermal Energy Office (HGEO) and National Energy Technology Laboratory (NETL) are seeking qualified applicants for non-exclusive sublicenses to one or both of the following DOE-supported technologies for commercialization in applicable fields of use.

The sublicensing structure for these technologies is established under licensing authorities and the Closeout and License Agreement between DOE and Southern Company Services (SCS), dated September 3, 2020, resulting from Cooperative Agreement DE-FC26-06NT42391 for a project entitled “Demonstration of a Coal-Based Transport Gasifier” in Kemper County, Mississippi, in which DOE acquired sublicense rights.  Under this structure, DOE will sublicense the Transport Oxy-Combustion (TROC™) technology including TROC patents and TROC information directly to approved sublicensees.  For the Transport Integrated Gasification (TRIG™) technology, including TRIG patents and TRIG information, as well as the Dual-Use TRIG technology, including the Dual-Use TRIG patents and Dual-Use TRIG information, SCS will directly grant sublicenses upon written request from DOE or an approved DOE sublicensee.

For the TRIG™ technology, the Kemper County integrated gasification combined cycle (IGCC) project's comprehensive technical data and engineering, construction, and operational details are documented in the final report available on OSTI.GOV.  For the full technical report, visit Kemper County IGCC (Final Project Report) (Technical Report) | OSTI.GOV

DOE also possesses and has rights to sublicense certain technical data and information related to the TROC™ technology pursuant to the Closeout and License Agreement.  Such information, if available, may be relevant to the utilization, practice, development, or improvement of the TROC™ technology and may include the following categories:

  1. Technology, process, and equipment descriptions
  2. Reports that detail the development of the TROC technology and serve as the basis for its design for commercial applications
  3. Relevant experience and operation information documentation
  4. Risk assessment documentation
  5. Comparison with other processes documentation
  6. Conceptual Design Reports:
    1. TROC Conceptual Design: 100 MW Gross Power Generation Technical Report
    2. TROC Conceptual Design: 500 MW Gross Power Generation Technical Report

These reports include block flow diagram, process and unit descriptions, steam system, balance of plant description, process flow diagrams, heat and material balance model, auxiliary power consumption, heat rate, emissions, combustor heat exchanger (steam generators, superheaters, and reheaters) details, equipment lists and site and main equipment layouts.

  1. TROC™ 1000 MW preliminary design

B. TRIG™ Technology

The TRIG™ technology includes patents and data.  DOE has the right to have sublicenses granted to the TRIG™ patents in a certain field of use pursuant to the Closeout and License Agreement.  The TRIG™ patents include U.S. Patent Nos. 8,961,629; 9,181,502; and 9,150,800, including available foreign counterparts, which cover Apparatus, Components, and Operating Methods for Circulating Fluidized Bed Transport Gasifiers and Reactors; Gasification of High Ash, High Ash Fusion Temperature Bituminous Coals; and Second Stage Gasifier in Staged Gasification and Integrated Process, respectively.

DOE possesses and has rights to have sublicensed certain technical data and information related to the TRIG™ technology pursuant to the Closeout and License Agreement in a certain field of use.  Such information, if available, may be relevant to the utilization, practice, development, or improvement of the TRIG™ technology and may include the following categories:

Licensing Requirements

DOE has determined that licensing these technologies is in the public interest and that any resulting sublicenses will be administered in accordance with applicable Federal statutes and regulations, including Licensing of Government-Owned Inventions, 37 C.F.R. § 404, DOE Patent Licensing Regulations, 10 C.F.R. § 781, 15 U.S.C. § 3710c, and 35 U.S.C. §§ 207–209, as appropriate, and in accordance with the Closeout and License Agreement.

Any sublicenses granted by DOE will be fee-bearing or royalty-bearing and subject to applicable federal licensing requirements, including 35 U.S.C. § 209 and 37 C.F.R. § 404.  DOE also requires that products embodying the licensed inventions, or produced through use of the licensed inventions, that are sold or used in the United States be manufactured substantially in the United States.

A sublicensee may request a waiver or modification of applicable United States manufacturing or competitiveness requirements.  DOE may grant such a request where the sublicensee demonstrates, with quantifiable supporting data, that manufacturing in the United States is not commercially feasible and DOE determines that the requested waiver or modification would best serve the interests of the United States and the public.
