VI. Licensing Declaration

The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

Licensing Royalty-Free, Reasonable and Non-Discriminatory License to All Implementers
Licensing information, comments, notes, or URL for further information

Because of the relation of the Brotli Compression Algorithm (described in the above-identified IETF document) to the work of the W3C WebFonts Working Group, Google Inc. has published a patent statement for “Additional licensing information for the WebFonts Working Group specifications” relating to Brotli. Because the statement relates to an IETF document and because both the algorithm and statement have broader applicability than to fonts, that statement is noted here.
See the statement at: <>
For convenience of reference, the statement is reproduced here:
“Google is participating in the WebFonts Working Group and has thereby made the W3C Patent Policy RF commitment that flows from that participation. However, in section 8.2 of the W3C Patent Policy, claims relating to referenced material are excluded from the RF commitment: “the implementation of technology developed elsewhere and merely incorporated by reference in the body of the Recommendation”. It is anticipated that a Recommendation may issue from the WebFonts Working Group that, like the specification here <>, includes a normative reference to a compression algorithm known as the Brotli Compression Algorithm, for which a version of the specification is here: <>. To negate the effect of that exclusion for the Brotli Compression Algorithm in work being done in the WebFonts Working Group, Google hereby extends its RF commitment for the WebFonts Working Group in which it is participating as follows: if and when a Recommendation is published from that working group that includes a normative reference to the Brotli Compression Algorithm, Google’s RF commitment extends as if the text of that referenced specification of the Brotli Compression Algorithm had been directly included in the text of the W3C Recommendation. In addition, to facilitate the use of the Brotli Compression Algorithm in other applications, Google hereby provides a W3C RF commitment (that is not limited to font data) to the Brotli Compression Algorithm specification linked above and, if that specification leads to a final IETF RFC for Brotli, then to the specification in that RFC.”

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
