TiVo Sued for Patent Infringement 142
IQ had the first notice that TiVo, the Linux-friendly digital video recorder folks have been sued for patent infringement. Gemstar International Group Ltd. (StarSight Telecast Inc.) has filed a patent infringement suit against TiVo in a Califorinia court. They are alleging TiVo "willfully infringed certain Gemstar intellectual property by virtue of TiVo's deployment,
marketing, offers to sell and sale of personalized video recorder devices containing an unlicensed interactive program guide."
Need for Patents (Score:1)
Can somebody give any good reason in defense of the patent system?
Let's talk about typical excuses for keeping the patent.
Excuse (1) : It rewards the innovators and thus encourages innovation.
Answer:
Scientific discoveries have been done and will be done without any
patent system. Patenting slows down freedom of utilzing the fruits
those discoveries.
Innovation and inventions like TCP/IP, WWW, HTML, XML would have been
far less successful they were patented. Internet as we know today
would not have existed and there would have been BBSes operated by AOL
and Microsoft.
So, the patent system serves the purpose of creating new monopolies or
entrenching the current ones. Patents just raise barriers to entry for
new smaller innovative players to the market. That's why established
big market players love the patent system and they patent everything
that comes to mind. Patents are used as tools to reduce competition
and thus hinders innovation.
Excuse (2) : The inventors need to eat too and recoup the cost.
Answer:
Then let the inventor keep his/her technology a trade secret. If that
technology is really that non-obvious, then he would get a significant
headstart in the market before the competitors can reverse-engineer it
or come up with their own competitive invention. Keep/make
reverse-engineering legal but keep stealing trade-secret illegal.

Ok, moron, economics 101 is in session.
Companies exist to make money. They do this by selling new, innovative products. Innovation costs money. If somebody else can copy that product as soon as it goes to market, they can sell their version at a lower price, because the copy cost far less to develop than the original. The consumers seek the lowest price for the product so they buy the immitation. The innovating company makes no money, and promptly goes bankrupt. Other companies see this, and decide that innovation is too risky. Technological progress halts.
The way to avoid this downward spiral is to grant companies patents on new and innovative products, to allow them to recoup their R&D costs. Patents should be granted for products not for ideas. That is the problem with patents right now; companies are patenting ideas, and obvious ones at that. (iirc, atari holds a patent on XOR'ing pixel values) Reform is necessary, but abolition of patents would be just plain stupid.

Gemstar patented the program guide quite a while ago (VCR+ - late '80s?). They have complete control over assigning the VCR+ control numbers listed in TV Guide and broadcast to your TV. Their patents are actually broader than just the "program guide" concept, and, yes, it is *very* profitable for them.
TiVo probably does infringe on the patents - they are not narrowly-focused. And Gemstar will probably soak them for a good bit of change, unless TiVo has an ace up their sleeve.
Gemstar is not a late-comer to the market, and at the time VCR+ *was* an innovation (consider some of the other patents listed in this arena in comparison). I hate the patent system, too, but depending on the "infringement", Gemstar probably has TiVo by the short hairs.
I wonder if we need to shorten the lifetime of a patent... In this world, a 17?-year patent is forever. In defense of the system, though, remember: the assembly line in retrospect is something just about anyone could have come up with - a simple business model which had immense impact.

The phone line on TiVo is only for receiving the guide information. Nothing is passed back to TiVo Central. Any "Season Pass" and "Favorites" processing is done locally, so TiVo doesn't know about your habits.
Besides, TiVo works independently of the programming source. If you use satellite because you can't get local programming (including PBS), sending overscan info over PBS is useless. Phone line transmission is really the only practical way to transfer the information.
Finally, you had to have the phone line to make DIVX useful. If you didn't plan on using the DIVX functionality you would buy a DVD player, saving $100. With TiVo, you don't have to hook it up if you don't want. You lose season-pass and TV Guide, but the rest of the functionality is intact.
The two situations are vastly different, IMHO.

Gemstar [gemstar.com] has been doing this kind of crap for years. They get the bulk of their revenue from patent licenses. Diva [divatv.com] and other video on demand companies (like Intertainer [intertainer.com]) have been trying to dance around Gemstar by using circular, pie-shaped menus instead of grids (Gemstar's patents cover pretty much anything with time on one axis and channels on another).
Consumer electronics companies (like the one [sony.com] that I work for, at least for the next few days) have been trying to design around Gemstar for years as well, and so far have not been successful. Believe me, with how much Gemstar charges and how thin the margins are on VCRs, this means big money. CE manufacturers have spent lots of time and resources on this - even Diva and Intertainer and such, I think, are just on the hairy edge of Gemstar's domain.
Of course, Gemstar's patents are ridiculously broad, and no sane patent system would consider their patents to be something that "a competent practitioner would not find obvious". So what you have here is the classic legal situation of "How much will it cost to make this problem go away?" Will it cost more to pay the lawyers or to pay off the settlement, license fees, what have you.

Well apparently you can patent a type of marketing. That's what Amazon did and people here were really pissed off about that a few weeks ago. IIRC that patent pretty much amounted to the great marketing practice of writing down your customer's name and address so that they only have to tell you once.
Overall I think that the idea of patents is a good thing. However patents should be distinguished from the current practices of patent law. The current state of patent law is not good at all.
Around here we seem to have a real habit of bitching about the greed of corporations that is manifested through the the current miserable state of patent law. I hereby respectfully submit that the problem is not necessarily greed in and of itself (greed being a prime motivator in a capitalish economy, superceeded perhaps only by sloth) but that the system we have in place fails to properly channel that motivation into productive forms. What we should be discussing here is not how greedy corporations are but what kind of system would properly reward those (both individuals and corporations) who have new ideas.
