A patent is the intellectual property right granted by the U.S. Government to an inventor "to exclude others from making, using, offering for sale, or selling the invention throughout the U.S. or importing the invention into the U.S." for a limited time in exchange for public disclosure of the invention when the patent is granted. In most cases, this is twenty years from the date of application. In some situations, the term of the patent may be extended due to delays in the processing of the application. After the patent has expired, the invention becomes public domain. In addition, patent owners must pay a maintenance fee at 3.5, 7.5, and 11.5 years after issue or else the patent will expire.

"A technical report (also scientific report) is a document that describes the process, progress, or results of technical or scientific research or the state of a technical or scientific research problem. It might also include recommendations and conclusions of the research. Unlike other scientific literature, such as scientific journals and the proceedings of some academic conferences, technical reports rarely undergo comprehensive independent peer review before publication. They may be considered grey literature. Where there is a review process, it is often limited to within the originating organization. Similarly, there are no formal publishing procedures for such reports, except where established locally." - from Wikipedia

Students, faculty, and staff have full access to the ASTM and IEEE standards databases. The Accuris database can be searched to find other current standards. Any standard that is needed for a class project or research can be acquired for UA faculty, staff, or students by contacting Paula Johnson for assistance. Please send the standard number, title and any other useful information to pcjohnson@arizona.edu.
The library has access to ASTM and IEEE standards (see links below). ASTM develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems and services. IEEE standards cover electrical engineering, and computer science, electronics and allied fields.
NIST, the National Institute of Standards and Technology, is an agency of the United States Department of Commerce promotes American innovation and industrial competitiveness by advancing standards, measurement science, and technology in ways that enhance economic security and improve quality of life.They offer the NIST Standards Incorporated by Reference (SIBR) Database - a searchable collection of standards referenced in regulations - Voluntary consensus standards, government-unique standards, industry standards, and international standards referenced in the Code of Federal Regulations (CFR).
To search for military standards, the Department of Defense has the ASSIST database.One needs to register to use the database.

You have an idea for an invention — or have gone so far as to create a prototype. Before marketing your invention, you will need to determine if your invention has already been patented. To do this, conduct a thorough patent search. This will usually involve searching a number of different patent sites, so it's useful to keep a log of all your search activity to avoid duplicate efforts.
See General Information Concerning Patents and Patent Process Overview for more information.
You can begin your search the following way:
1. Brainstorm keywords to describe your invention — think of synonyms.
2. Use your keywords to search for a similar match of your invention in Google Patents. The Advanced Search in Google Patents lets you enter phrases, exclude a word, etc.
3. If you find a similar invention, write down its class and subclass.
4. Use the class and subclass to search patents and patent applications at the USPTO website classification search.
[Note: The default search is CPC (Cooperative Patent Classification), which harmonizes the former European Classification (ECLA) and United States Patent Classification (USPC) systems.]
5. Trace related patents through references.
