+<h1>Other disclosures</h1>
+While Xiph.Org, Broadcom, and Microsoft filed IPR disclosures giving
+ royalty-free licenses to their patents used in Opus, two companies that did
+ not directly participate in the development of Opus, Qualcomm and Huawei,
+ filed IPR disclosures with potentially royalty-bearing terms.
+The IETF allows <b>anyone</b> (and their dog) to file an IPR disclosures if
+ they <b>think</b> that their patents "covers or <b>may</b> ultimately cover"
+ a standard.
+In fact, for any organization who can be said to have <i>contributed</i> in any
+ (very loosely defined) way, these IPR statements are not just allowed, but
+ required.
+It is thus safer for organisations to declare as much as they can.
+As an example, one can find similar non-free Qualcomm IPR statements on both
+ <a href="https://datatracker.ietf.org/ipr/1390/">SIP</a> and
+ <a href="https://datatracker.ietf.org/ipr/1389/">SDP</a>.
+To our advantage, however, the IETF IPR disclosure policies require companies
+ to provide the actual patent numbers.
+This allows anyone to verify these claims for themselves, which is definitely
+ a good thing.
+Unfortunately, when it comes to patents, it is difficult to say much without
+ making lawyers nervous.
+However, we can say something quite direct: <b>external counsel has advised us that Opus can be
+ implemented without the need to license the patents disclosed by Qualcomm or
+ Huawei</b>.
+We can also say that Mozilla is confident enough in Opus to ship it to hundreds
+ of millions of Firefox users.
+Similarly, Cisco is also supporting Opus in at least one product.
+More companies are expected to do the same soon.
+Mozilla invested significant legal resources into avoiding known patent
+ thickets when designing Opus.
+Whenever possible, we used processes and methods that have been long known in
+ the field and which are considered patent-free.
+In addition, we filed numerous patent applications on the new things we 
+ invented to help defend the Opus community.
+As a result, Opus is available on a royalty-free basis and can be deployed by
+ anyone, including other open-source projects.
+Everyone knows this is an incredibly challenging legal environment to operate
+ in, but we think we've succeeded.
