After all, this is not the first time that NTT Docomo has formed consortiums with a number of Asian handset and chip vendors to launch similar projects. Each time, there’s been one mission in mind: catering to NTT Docomo’s needs.

So, what next? A closer tie with NTT Docomo could be a logical solution for Fujitsu to achieve its ambition, hopefully rivaling Renesas Mobile as a key player in the next LTE modem market.

Third, get ready for the looming IP battle over NTT Docomo-flavored LTE implementations – especially among those chip suppliers who have served and worked with NTT Docomo together.

Clearly, NTT Docomo has a big stake in its own IPs.

But, since many partners” have pitched in to implement Docomo’s LTE solutions, it is not clear how much intellectual property — developed under Docomo’s initiative — solely belongs to Docomo.

There is little doubt, though, that Docomo will continue to call the shots within the new joint venture. A big question, then, is how Renesas Mobile, cut off from the new consortium, would respond to the LTE IP battle of the future.

Much of the shifting power grabs among Japan’s number one mobile carrier and Japanese electronics companies may strike you as inside baseball – only applicable in Japan. And you have every right to feel that way.

After all, this is not the first time that NTT Docomo has formed consortiums with a number of Asian handset and chip vendors to launch similar projects. Each time, there’s been one mission in mind: catering to NTT Docomo’s needs.

Recent examples include the joint development – among Fujitsu, NEC, Panasonic Mobile Communications, Sharp, Renesas and NTT Docomo – of an application processor platform for feature phones (running Symbian and Linux), announced in the spring of 2010. LiMo Foundation, an industry consortium dedicated to creating the hardware-independent, Linux-based operating system for mobile devices, is another example.

However, such joint efforts, despite the grandeur of each alliance, have borne scant fruit so far on the global market

Some experts wonder whether Intel is taking a new tack in corralling its rights to IA-64. That is, rather than submit garden-variety claims to the U.S. Patent and Trademark Office (USPTO), Intel is trying to patent the functions carried out by specific instructions. In doing so, the company appears to be, in effect, trying to patent the IA-64 instruction set itself.

Intel has a long history of fending off cloners with a broad hardware-based patent portfolio. The IA-64 move highlights the growing importance of software in electronics designs and the need to protect those software innovations.

I don't think that they Intel are going to license these patents,” said Rich Belgard, a microprocessor consultant based in Saratoga, Calif. I think they want to protect the IA-64 from cloning.”

Itanium, which is the first chip in the IA-64 family, is already in the hands of Intel OEMs. The second processor, dubbed McKinley, is due next year.

Intel's strategy may be more than an academic exercise. For one, Mips Technologies Inc. has been fighting a year-long, still-ongoing court case against Lexra Inc. of San Jose, claiming that Lexra infringed four instructions protected under its 1989 patent No. 4,814,976, titled RISC computer with unaligned reference handling and method for the same.”
