Q's patent 4,901,307 states the following: The communication system 10 uses spread spectrum signal transmission techniques to increase user capacity by establishing coded digital communication signals that use quasi-orthogonal bit sequences to decrease mutual interference. At the same time, the communication channels are spread across or occupy the entire allocation bandwidth, which improves communication quality, allows for increased bandwidth signals and decreases the effects of frequency selective fading. Spread spectrum communication involves processing the outgoing information signal with a spreading function which changes or expands a narrow bandwidth signal into a broad bandwidth signal. The spreading function is a reproducible function which spreads the narrow bandwidth transmission signal over a broader bandwidth and reduces the peak spectral density of the signal. This is direct sequence spread spectrum coding. Alternatively, the carrier frequency can be pseudo-randomly hopped over the spread bandwidth. Direct sequence spread spectrum is preferred for applications addressing multipath impairments. The first IDCC patent that mentions a concept similar to spread spectrum CDMA is 5,081,643. How then, Gussie, can you say that you came up with some interesting results that "...amplify the fact [sic] that IDC's broadband CDMA efforts preceded and then became parallel to QCOM's narrowband CDMA effort". Mind showing me where IDC's patents precede Q's spread spectrum patents? Why aren't IDC's patents mentioned in Q's description of the art? Why didn't the patent examiner catch this prior effort by IDC? Perhaps the answers say a lot about why Q's royalty stream is like Niagara Falls compared to IDCC's dry gulch. OK, Gussie, you can load up your poison pen and start the insults and vile now.
