JPO; here's the play-by-play for the list posted earlier, I have accumulated data on 27 applications/patents; noteworthy is that 16 relate to CDMA systems and 1 to TDD/CDMA.
One CDMA patent has been issued (3,377,983 Spread Spectrum Interference Elimination)), one CDMA application was rejected by the JPO in April 2004 (Subscriber Station) and it's not recorded if IDCC has appealed. The others are all still under examination.
I can trace 4 TDMA patents (there may be others but I can't track some pre-2000 references). We know from IDCC that 2 (2,816,349 and 2,979,064) were revoked in Oct '01 and are being pursued through the court by IDCC. There is a third patent (3,186,733) that's believed to be subject to challenge/revocation. These all relate to the 1985 US Paneth patents.
In addition, there are two rejected applications that are on appeal at the JPO (from 2002) and at least one relates to FDMA/TDMA Radio Digital Telephone System.
One additional FDMA/TDMA application was abandoned in Feb 2003.
I have the data in Excel form if anyone is interested. Or, if Jim can post it, I will email it to him.
So far, I haven't been able to track down what's happening with patents that impact Matsushita but have sent an email to the JPO asking for information. JK
