Informa has IDCC with 21% and QCOM with 19%. The Koreans had QCOM and IDCC each with 13%. The Tech IPM guy has QCOM in the lead. Who knows who is correct? The one thing I believe from reading ll these reports is that IDCC is neck and neck with QCOM for the lead in essential LTE patents.
I think IDCC was busy working on LTE standards 5-8 years ago, while QCOM was resting on their CDMA laurels just a bit. That's one of the reasons they bought Flarion (to fill some IP gaps).
I don't think it's that strange. Qualcomm basically owns CDMA, of course, and they were a small company by market cap until 1999. Also their presence in LTE isn't as strong as CDMA. Interestingly, a large % of Qualcomm's LTE patents weren't even developed by them but were acquired from Flarion in 2005 for around $700mm if I recall correctly...
