This article from 2008 speculates: "The royalties will be split among several players, said Doherty. Blu-ray has a lot of grandfathers. A lot of people call it a Sony standard but by our estimates Sony doesn't even have 30 percent of the IP," Doherty said. The top four intellectual property holders are likely Sony, Panasonic, Pioneer, and Warner." http://news.cnet.com/8301-10784_3-9874317-7.html "Sony doesn't even have 30 percent" sounds to me like they could be somewhat close to that number. |
Even counting only the 9 initial members and taking into account those four were the top IP holders, they'd have to divide a share smaller than 100%, as the others members have a share too. Then you must add the other 9 members that entered later, each one giving its big or little contribution. TDK gave a big one, amongst its tech contributions there was one for hardening the external layer of the discs enough to not require a cartridge. Then there is Oracle, owner of Java, used as basis for BD-J. Then there are the patents cross-licensed on audio and video codecs, processing and filters. Then there is one of the most important techs in BD, and its most iconic, the blue laser diode itself, Sony owns part of the techs of one of the most widespread implementations, but it isn't the sole owner of it and it hasn't exclusive rights on it, this contributes to further divide royalties on the most important patents of the standard. And all this just to mention the most known contributions. "Doesn't even have 30%" doesn't necessarily mean "close to 30%", it depends on the context, and this one was quite negative, about denying that BD was a mainly Sony-owned standard. Add that he wrote "the top four are LIKELY", not surely and implying their share exceed the one of others but not overwhelmingly. Anyhow, as I wrote, stretching Sony's estimated share to 20% starts being in the difficult range, but not impossible or unlikely, stretching it further becomes unlikely. We are still in the same order of magnitude for the estimate, anyhow, unlike those that underestimate Sony's share putting it around or below 10% and underestimating the royalties due on each console too, making the order of magnitude drop from hundreds to tens million $. Anyhow, as I wrote, MS adoption of BD will probably help Sony in a far larger measure than the money directly given to it.
