This tab-delimited file, stc2015_5yr.tsv, prepared from the U.S. Patent and Trademark Office (USPTO), Technology Assessment and Forecast (TAF) database, displays a listing of geographic regions from which utility patents (i.e., patents for invention) originated during the indicated 5 year time period and a corresponding count of patents for each of the years of the period. Each displayed annual count corresponds to the count of patents received in a calendar year (January 1 to December 31). It will import into a Microsoft Excel spreadsheet.

The PatentsView API is intended to inspire the exploration and enhanced understanding of US intellectual property (IP) and innovation systems. The database driving the API is regularly updated and integrates the best available tools for inventor disambiguation and data quality control. We hope researchers and developers alike will explore the API to discover people and companies and to visualize trends and patterns across the US innovation landscape.

Offers exclusive access to patent application status information for unpublished patent applications only to the applicant/inventor or his/her representative(s).

Every Federal agency that operates or directs one or more Federal laboratories or that conducts research and development is required to prepare and submit an annual report of its technology transfer activities as described in 15 U.S.C. § 3710(f).

Standard Reference Material 1632d Trace Elements in Coal (Bituminous) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques used in the analysis of coals and materials of a similar matrix. A unit of SRM 1632d consists of 50 g of bituminous coal that was ground to pass a 250 µm (60 mesh) sieve, homogenized, bottled under an argon atmosphere, and sealed in an aluminized bag. This data is public in the Certificate of Analysis for this material.

SRM 1635a Trace Elements in Coal (Subbituminous) - This Standard Reference Material (SRM) is intended primarily for the evaluation of techniques used in the analysis of coals and materials of a similar matrix. A unit of SRM 1635a consists of 50 g of subbituminous coal that was ground to pass a 250 µm (60 mesh) sieve, homogenized, bottled under an argon atmosphere, and sealed in an aluminized bag. This data is public in the Certificate of Analysis for this material.

Standard Reference Material 2682c Subbituminous Coal (Nominal Mass Fraction 0.5 % Sulfur) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques used in the analysis of coals and materials of a similar matrix. A unit of SRM 2682c consists of 50 g of subbituminous coal that was ground to pass a 250 µm (60 mesh) sieve, homogenized, packaged in an amber glass bottle under an argon atmosphere, and then sealed in an aluminized bag. This data is public in the Certificate of Analysis for this material.

SRM 2683c Bituminous Coal (Nominal Mass Fraction 2 % Sulfur) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques employed in the determination of sulfur, mercury, and chlorine in coal and materials of a similar matrix. A unit of SRM 2683c consists of 50 g of bituminous coal ground to pass a 250 µm (60 mesh) sieve, homogenized, packaged in an amber glass bottle under an argon atmosphere, and sealed in an aluminized bag. This data is public in the Certificate of Analysis for this material.

Standard Reference Material 2684c Bituminous Coal (Nominal Mass Fraction 3 % Sulfur) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques used in the analysis of coals and materials of a similar matrix. A unit of SRM 2684c consists of 50 g of bituminous coal that was ground to pass a 212 µm (70 mesh) sieve, homogenized, packaged in an amber glass bottle under an argon atmosphere, and then sealed in an aluminized bag. This data is public in the Certificate of Analysis for this material.
