Oh please, stop with this FUD. JPEG2000 is no different to Ogg or VP8 in that regard, both of which Mozilla is happy to ship. It was designed to be usable without having to licence any patents. Any known patents have been waived. The possibility of unknown patents remains but is vanishingly small by this point (other organisations much larger than Mozilla have been shipping JPEG2000 code for years).

>Furthermore, it includes guidelines and examples, a bibliography of technical references, and a list of companies from whom patent statements have been received by ISO. JPEG 2000 was developed with the intention that Part 1 could be implemented without the payment of licence fees or royalties, and identified patent holders have waived their rights toward this end. However, the JPEG committee cannot make a formal guarantee, and it remains the responsibility of the implementer to ensure that no patents are infringed.
What the fuck does Mozilla even mean by "free format" these days? It's an ISO standard, it was designed to be usable without paying any fees, there is a waiver of any known patents, it's been used across the industry for years without legal problems. I can't think of a single way that it could be made "more free". The only possible reason I can see is that it wasn't invented by Mozilla/Xiph. And really that is just pathetic and very much a "nasty attitude".
