Contains the images of each patent application (non-provisional utility and plant) published weekly (Thursdays) from March 15, 2001 to present in Portable Document Format (PDF) created from the Patent Application Single-Page TIFF Images.

Contains the images of each patent application (non-provisional utility and plant) published weekly (Thursdays) from March 15, 2001 to present in Tagged Image File Format (TIFF) Revision 6.0 with CCITT Group 4 Compression (single-page TIFFs).

Contains detailed information on roughly 6 million patent assignments and other transactions recorded at the USPTO since 1970 and involving over 10 million patents and patent applications.

Contains daily (front file - Calendar Year 2022) and annual (backfile - August 1980 - December 31, 2021) patent assignment text (no drawings/images) derived from patent assignment recordations made at the USPTO.

Patent Examination Data System lets customers retrieve and download multiple records of USPTO patent application or patent filing status at no cost. PEDS contains the bibliographic, published document and patent term extension data tabs in Public PAIR from 1981 to present. There is also some data dating back to 1935. Customers can download the entire dataset containing the data for all indexed documents. There are over 13 million records in PEDS. The data can be accessed by anyone using the web interface or the provided Application Programming Interface (API).

Contains detailed information on 9.2 million publicly viewable patent applications filed with the USPTO through December 2021. The data are sourced from the Public Patent Application Information Retrieval (Public PAIR) system. There are several data files, each of which coincides with a tab on USPTO's Public PAIR web portal. The data files include information on each application's characteristics, prosecution history, continuation history, claims of foreign priority, patent term adjustment history, publication history, and correspondence address information.

Contains detailed U.S. District Courts patent litigation data on 74,623 unique court cases filed during the period 1963 - 2016. The data was collected from the Public Access to Court Electronic Records (PACER) and RECAP as sources for all of the content.

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.

This database provides access and search capability for NIST critically evaluated data on atomic energy levels, wavelengths, and transition probabilities that are reasonably up-to-date. The Atomic Spectroscopy Data Center has carried out these critical compilations. The Data Center is located in the Physical Measurement Laboratory at the National Institute of Standards and Technology (NIST).

Standard Reference Material 131h Refined Cast Iron - This Standard Reference Material (SRM) is intended primarily for use in validation of chemical and instrumental methods of analysis. It can be used to validate value assignment of in-house reference materials and, if necessary, to calibrate carbon/sulfur analyzers. A unit of SRM 131h consists of a bottle containing 100 g of chips. This data is public in the Certificate of Analysis for this material.
