Patent Document Delivery Service Over the Internet

Chemical Abstracts Service (CAS) has announced Internet delivery of all U.S. patents since 1974 via CAS's new service, Chemical Patents Plus, part of the CAS Document Detective Service (DDS). Chemical Patents Plus incorporates a specially indexed collection of U.S. chemical patents and rotatable 3-D structure views for many CAS Registry Numbers via browsers that support JAVA.

Chemical Patents Plus gives the user enhanced chemical patent information, including CAS indexing data and chemical structure illustrations, easy search access, a variety of display formats, and complete text of patents issued by the U.S. Patent and Trademark Office (USPTO) since 1974, with partial coverage of selected technologies from 1971-73. Chemical patent records include searchable CAS indexing data for the invention (including CAS Registry Numbers) based on the U.S. patent or a foreign equivalent. Two-dimensional and rotatable three-dimensional structure views are also available for many CAS Registry Numbers. Complete image pages, in high-resolution format, for all U.S. patents issued since January 1, 1993, are also available for downloading.

Users can access the full capabilities of Chemical Patents Plus via the CAS home page at or directly via the Chemical Patents Plus home page at A free demo of the service will be available.

Companies involved with chemical commerce in Japan now have access to regulatory information for more than 41,000 records pertaining to Japanese Inventory substances. Online availability enables users to access this information by CAS Registry Number, chemical name, and ENCS classification numbers. The information will also be available on CASurveyor: Regulatory Compliance in 1996.

* Users of CAplus, the most current database providing access to Chemical Abstracts (CA) information, can now set up a table of contents (TOC) alerting service using an online command on STN International.
