There are three principal exclusions from the export regulations:

1. Public Domain / Publicly Available Information (i.e., materials available in newspapers, libraries, or presented at publicly available conferences and trade shows, publicly available technology or software, websites accessible to the public for free and without the host’s knowledge or control of who visits the site, and published patents);
2. Educational Information, i.e., "information concerning general scientific, mathematical, or engineering principles commonly taught in schools, colleges, and universities" (see ITAR §120.10(b)), and information by "instruction of a catalog course or associated teaching laboratory of an academic institution" (see EAR §734.3(b)(3)(iii)); and
3. Fundamental Research (i.e., basic or applied research in science, mathematics and engineering where the resulting information is ordinarily published and shared broadly within the scientific community, and for which the researchers have not accepted restrictions for proprietary or national security reasons).
