You're referring to Sherwin Seligsohn who started PANL (Universal Display) on the basis of OLED technology from a consortium based in Princeton. His family has reduced its original IMM stake over the years and he no longer controls the compnay. Sherwin Seligsohn is the investor who founded International Mobile Machines, IDCC's predecessor company, in 1972. IMM may have been a financial underperformer over the years but it did a lot of the groundbreaking work that made it possible to commercialize TDMA. Hughes was one of the first TDMA licensee in the mid-80s. Key IDCC TDMA patents have already been validated in Sweden and Germany. The 1995 Pre-Markman jury loss to Motorola invalidated key portions of IDCC's TDMA patents, but IDCC was able to have key portions revalidated by the US Patent Office late last year. Anyway, IDCC was a TDMA shop until 1992 when it merged with Donald L. Schilling's SCS companies to combine Schilling's pioneering work on CDMA with IDCC's pioneering work on TDMA. As events are proving, IDCC correctly anticipated that TDMA was going to be the dominant technology platform for wireless and CDMA would have to be eventually layered over TDMA networks. Further, Schilling, who many credit for pioneering PCS in this country, always contemplated using his broadband CDMA with a wider spectrum than was available in the early 90s so this partly explains why it ultimately agreed to cross-license its 5 CDMA patents to QCOM for $5.5 million for use only under 10 MHz. QCOM was willing to work with the 1.5 MHz spectrum additions to the A and B channels to commercialize its own brand of CDMA technology. Schilling no longer works at IDCC, having left in 1996 to join Golden Bridge Technology to pursue his work on key 3G/4G components. ATT, which licensed IDCC's TDMA and CDMA patents in 1994, was also the first licensee of GBT's CDMA patents so that gives you an idea of the quality of his work. ATT, ERicsson, IDCC, GBT and some others were involved in developoing the North American version of WCDMA, which have been folded into the combined Asian and European versions. Lastly, you are correct that Nokia and IDCC have been working on the TDD version of WCDMA for over 18 months now. Note that QCOM has not even trialed the data portion of its 1XRTT technology yet. The FDD version of WCDMA is expected to rollout first over the next few years before the TDD version will extend its capabilities under WCDMA's hierarchical cell structure.
