IEEE-SA RECORDS OF IEEE STANDARDS-RELATED PATENT LETTERS OF ASSURANCE
The IEEE-SA Records of IEEE Standards-Related Patent Letters of Assurance list IEEE Standards for which Letters of Assurance (LOA) have been received from patent owners in accordance with the IEEE-SA Patent Policy. The Patent Policy is set forth in Section 6 of the IEEE-SA Standards Board Bylaws. Operational procedures relating to the Patent Policy are found in Section 6.3 of the IEEE-SA Standards Board Operations Manual.
It was first compiled in 1993 to provide information about the known patents that may affect the practice of IEEE Standards. Information about LOAs from 1993 forward have been posted. Some LOAs received prior to 1993 have also been included (others may only be available in archived IEEE files).
An updated report is posted as new or revised information becomes known.
IEEE is not responsible for identifying patents or patent applications for which a license may be required to implement an IEEE standard or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
IEEE takes no position with respect to the reasonableness of rates, terms, and conditions of the license agreements offered by patent holders or patent applicants. To that end, IEEE will not review and does not endorse the contents nor confirm the continuing accuracy or consistency of any web sites listed in any patent letters of assurance received.
