"For over 200 years, the basic role of the United States Patent and Trademark Office (USPTO) has remained the same: to promote the progress of science and the useful arts by securing for limited times to inventors the exclusive right to their respective discoveries (Article 1, Section 8 of the United States Constitution). Under this system of protection, American industry has flourished. New products have been invented, new uses for old ones discovered, and employment opportunities created for millions of Americans. The strength and vitality of the U.S. economy depends directly on effective mechanisms that protect new ideas and investments in innovation and creativity. The continued demand for patents and trademarks underscores the ingenuity of American inventors and entrepreneurs. The USPTO is at the cutting edge of the Nation’s technological progress and achievement.
The USPTO is a federal agency in the Department of Commerce. The USPTO occupies five interconnected buildings in Alexandria, Virginia. The office employs over 7,000 full time staff to support its major functions--- the examination and issuance of patents and the examination and registration of trademarks.
The USPTO has evolved into a unique government agency. Since 1991--under the Omnibus Budget Reconciliation Act (OBRA) of 1990--the agency has been fully fee funded. The primary services the agency provides include processing patent and trademark applications and disseminating patent and trademark information.
Through the issuance of patents, the USPTO encourages technological advancement by providing incentives to invent, invest in, and disclose new technology worldwide. Through the registration of trademarks, the agency assists businesses in protecting their investments, promoting goods and services, and safeguarding consumers against confusion and deception in the marketplace. By disseminating both patent and trademark information, the USPTO promotes an understanding of intellectual property protection and facilitates the development and sharing of new technologies worldwide." from web site
Access to bibliographic and full-text patent databases of the US Patent and Trademark Office (PTO).
"The Science Accelerator empowers you to search, via a single query, important information resources of the U.S. Department of Energy's (DOE's) scientific and technical information. These resources contain the results of DOE research and development (R&D) projects and programs, descriptions of R&D projects under way or recently completed, major R&D accomplishments, and recent research of interest to DOE. The Science Accelerator can be used to search:
- Electronic full-text research reports (including DOE scientific and technical information)
- Energy citations (millions of them, going back to the Manhattan Project era)
- Ongoing research project summaries (what's happening right now in DOE science research)
- Wonderful DOE accomplishments in science
- E-prints (journal article pre-publication drafts, scholarly papers, and more)
- Proceedings and papers from science conferences
- More resources"
"Science.gov is a gateway to government science information and research results. Currently in its fifth generation, Science.gov provides a search of over 36 scientific databases and 200 million pages of science information with just one query, and is a gateway to 1,850+ scientific Websites.
