TiVo Time Warp Judgment Affirmed 107

zapakh writes "A federal appeals court this week upheld a lower court decision that accused DISH Network and EchoStar of continuing to infringe on TiVo patents.' This is a follow-on to a Slashdot story from October. Despite a 'Herculean effort' by EchoStar in redesigning its DVR software, the ruling agrees with the district court that that was not a major redesign of the software. The patent in question is titled 'Multimedia time warping system.' TiVo is pleased with the ruling."

        I'm not sure why EchoStar couldn't use a similar technique; unfortunately, it's possible that the courts interpret the patent broadly and figure that difference doesn't matter.

        Such an interpretation seems probable. From the fine ruling, as linked from TFA (look for "2. Infringement of the '389 Patent"), emphasis mine:

        EchoStar argues that because TiVo failed to prove by clear and convincing evidence that the redesigned devices infringe, it is not in contempt of the infringement portion of the injunction. ...[A]t the very list, the claim limitation "parses video and audio data from said broadcast data" is not met by its new software. It argues that the district court improperly found infringement based on the simple fact that the software includes a PID filter [a mechanism designed to distinguish between various television programs] that parses some data. The filter, however, EchoStar argues, looks only at the header of a data packet, not the payload where the video and audio are contained. Therefore, EchoStar urges, its modified software does not parse any audio and video data.

        TiVo responds that the district could has previously construed the term "parses" broadly to mean "analyzes," a construction that has never been challenged, and all that is required for the modified software to meet this limitation is a component that analyzes video and audio data. TiVo argues that EchoStar's attempt to differentiate header data from the packet payload is improper because both are part of an MPEG packet, and the whole packet is video and audio data. Moreover, TiVo argues that experts for both sides testified at trial that PID filtering meets the parsing limitation under the court's claim construction.

        The ruling is a great read, and great fodder for at least one aspect of what is wrong with software patents, even when they verge on hardware. EchoStar provides a DVR feature that is found to infringe a patent. In response to an injunction, EchoStar implements around the infringing idea by doing something it called "Indexless DVR". Now they're found in contempt o

        • The court clearly didn't understand the language. They accepted the idea that because Echostar refers to PID filtering as "parsing", they were admitting that PID filtering was "parsing video and audio data". Which is just wrong; the video and audio data are at a different level of abstraction from the container which was being parsed. The court simply doesn't understand the word "parsing" and uses it as if it has some universal meaning outside the context of what is being parsed.

          It doesn't help that what

      • It's likely that they don't want to store the butt tons of mpeg-2 video without compressing the streams first.
  • So their patent is based on the ability to record one video stream while watching something else? Multi-tasking isn't exactly rocket science; computers have been doing it for decades. Furthermore, you could accomplish the same "time warping" effect as far back as the 1970s without even using a computer; all you needed was a VCR and an RF splitter.

    Implementing simultaneous recording and playback, with quick seeking to any point in the stream, and doing so with a very low-cost system (in TiVo's case, originally a 50MHz PowerPC) is not at all trivial.

    There's more than one way to implement such functionality in hardware, but TiVo found a way that was cheap and effective before Echostar did, and Echostar didn't bother to license TiVo's patent or find another method.
