It's funny that you should mention commercial browsers as possibly being affected by an W3C RAND policy. It turns out that modern browsers already include standards that are subject to the ITU's RAND licensing policies. For instance, V.42bis is an ITU standard for data compression and is included with just about every commercial browser that I can think of. Its core algorithm (LZW and related variants) are patented by Hughes, Unisys, IBM and others. Many of these patents holders have attempted to assert their patents for profit at various times. In fact, at one point early in the online revolution Unisys went after Compuserve for using LZW for its data compression standard. The users of Compuserve put up such a stink that Unisys backed down to some extent. Unisys publicly said that it would not seek a royalty from Compuserve's users that simply decompress images, but they would seek a royalty (I think it was somewhere in the neighborhood of $.10/software copy) from those that used image compressor to post images. As far as I know, none of the V.42bis patent holders ever attempted to collect royalties for commercial browsers. I understand that this is at least partially the result of existing commercial relationships between the major players. I know of at least one smaller internet appliance company that had a very difficult time trying to license patents essential to the implementation of V.42bis from Unisys. This is yet another example of how it pays to be big when having to deal with a RAND licensing scenario. -Chuck Weinberger
