First and foremost, such standards allow for interoperability between different electrical components. JEDEC standards do not protect members from normal patent obligations. The designated representatives of JEDEC member companies are required to disclose patents and patent applications of which they are aware, assuming that this information is not considered proprietary. JEDEC patent policy requires that standards found to contain patented technology, whose owners do not sign a standard JEDEC patent letter, be withdrawn. Thus the penalty for a failure to disclose patents is retraction of the standard. Typically, standards are not adopted to cover technology that are subject to patent protection. In rare circumstances, standards covered by a patent may be adopted, but only on the understanding that the patent owner will not enforce such patent rights or, at a minimum, that the patent owner will provide a

This early work was followed by a number of test methods, JESD22, and product standards. For example, the ESD caution symbol, which is the hand with the line drawn through it, was published by JEDEC and is used worldwide. JEDEC also has a dictionary of semiconductor terms. All of JEDEC standards are
