The intellectual property that
represents the principal asset of AET is described in thirteen (13) U.S.
patents and one additional application awaiting action. AET also
holds a number of foreign patents in countries/areas where patent
protection is meaningful and local markets are seeking new technology.
In addition, AET personnel have published a number of industry/problem
specific essays and articles in several periodicals. For a complete
list of all articles, please contact us.
