What are Patents?

A patent is a set of exclusive rights which has been granted by a sovereign state (or sometimes as intergovernmental organization). Such rights are granted to an inventor, for a limited duration, in exchange for a detailed public disclosure of such invention. Patents typically exclude others from making or offering for sale those inventions.

Things to consider when looking for patents

Patents are generally granted from specific countries. Patent numbers often have prefixes that indicate which country granted the patent. For example, the patent US5577561A was generated from within the United States. Follow this link for a list of country codes That said, you may also encounter patents that have been generated from the World Intellectual Property Organization (WIPO) which is an organization created by the United Nations in 1967.

What Are Technical Standards?

Technical standards are agreed upon protocols that establish interchangeability between products. Standards can come from national and international organizations. In short, standards are the reason that we have compatibility of products across manufactures. There are a variety of both national and international standards organizations. Such agencies include (but are not limited to): The International Standard Organization (ISO), American National Standards Institute (ANSI), Institute of Electrical and Electronics Engineers (IEEE), Acoustical Society of America (ASA), American Section of the International Association for Testing Materials (ASTM), and National Electrical Manufacturers Association (NEMA).

What Standards Does the Roesch Library have?

The Roesch Library has a limited amount of hard copy standards. The collection includes American Welding Society and ASTM standards. You can search the library catalog and limit your search results to display only standards.  


Finding Standards Online

SAI Global - SAI Global is a very useful tool for locating information pertaining to standards.  It can be used to do broad subject searches or to find a particular standard number or standards regarding a specific subject. Although SAI Global is a great starting point, it does not provide full text access to standards. For this, you will have to search the other standards resources available at the University of Dayton.

Institute of Electrical and Electronics Engineers (IEEE) Xplore  - Comprehensive index of standards. Searches can be limited to display only standards.

American Society of Civil Engineers (ASCE) Standards - Provides technical guidelines for promoting safety, reliability, productivity, and efficiency across all areas of civil engineering.  

ASTM Standards - Provides full-text of standards regarding a broad range of disciplines.  

Occupational Safety & Health Administration (OSHA)Standards - Contains links to all current OSHA standards and information on the rule making process used to develop workplace health and safety standards.  


Purchasing Standards

If you are looking for other standards, you may be able to purchase them either from a vendor or the standards issuing agency. Unfortunately, standards can be extremely expensive depending upon the issuing organization. One recommended standards vendor is IHS. You can also ask for assistance from the Roesch Library staff.
