Charles Walton, the Father of RFID 169

Posted by simoniker from the rtfm-on-rfid dept.
Roland Piquepaille writes "In a very interesting article, the San Jose Mercury News tells us about Charles Walton, the man behind the radio frequency identification technology (RFID). Since his first patent about it in 1973, Walton, now 83 years old, collected about $3 million from royalties coming from his patents. Unfortunately for him, his latest patent about RFID expired in the mid-1990s. So he will not make any money from the billions of RFID tags that will appear in the years to come. But he continues to invent and his latest patent about a proximity card with incorporated PIN code protection was granted in June 2004. Maybe he'll be luckier with this one. This overview contains some excerpts of the original article. It also contains tips to search for Walton's patents and an image of the front page of his first patent."

      What would the patent holder have gained by making them prohibitive? Had his patent not expired, the only difference is he would have been richer. I'm sure the technology would still have been used... (Unless this guy is truly altruistic.)
      • You can look at this whole process in another way also.

        If one argues that the patent (and the licensing fees) was a major factor in the delay of RFID technology, I wonder how many other techs are out there that COULD DO great good for mankind, but isn't because of patent restrictions. Cures/Medicines, new engines/combustion tech, IT infrastructure/security/privacy boosting tech etc.

    • The cost of making the antenna is the largest factor in the price of the simplest RFID tags. The industry is pretty close to the elusive 5 cent tag, which has been the holy grail for some time. It is improved technology (as opposed to expiring patents) that has lead to the reduction in cost over time.

      Were the patent still in force he could charge less than a penny per tag and he would still get rich (there will be billions and billions of tags) and the cost wouldn't be prohibitive.

      If he insisted on a high fee, such as a dollar per tag that would certainly slow the adoption of the technology, but why would he do that?

      In the end the market would have dictated the price and it would be low in order to allow adoption of the technology and maximize his profit. In that case, what you are saying would not be any more applicable than it is today.

      Exactly!

      And this is how patents should be, IMHO.

      The inventor gets a fair benefit out of his invention, while the rest can explore and make use of it to everyone else's (and their) benefit down the line.

      These days, patents seem to exhibit the idea that the inventor should get a cut for every penny that's been made out of his/her invention. If this were the case, civilization would have long stalled.

      The ideal patent would be one where the inventor gets a fair benefit, and others can have a free go at the invention so that they can improvise and better it for everyone else.

      I do not see why he should be worried, especially since he's made enough already.

        What's unique about RFID is that the responding device (ie, the RFID tag on your clothes, or your Mobil Speedpass keychain, or your FreedomPay tag) isn't self-powered. Most RFID chips have no internal power source; they get their power from the RF waves broadcast from the RFID reader. The power from the RF waves powers the RFID chip long enough for the chip to power up, and broadcast a reply to the RFID reader's query.

        Now that's cool. And it's also what makes them so low-cost and useful (for good and bad). You can literally print those RFID tags; no need to include a battery.

    • Well, firstly: there are a lot of stupid inventions [totallyabsurd.com] (e.g.: hat that spreads into an umbrella).
      Secondly: there are a lot of inventions that are developed based on previous ideas and are fully exploited (e.g.: paperclips [about.com] - there are many designs, quite a few still being used).
      Thirdly: many inventions are innovative, but just not quite good enough [tripod.com] to use (e.g.: the development of the zipper [askandyaboutclothes.com] took several tries).
      Fourthly: The technology is often not good/economical enough in practice (e.g. Lilienfeld's invention [huji.ac.il]

    Then, when some company wants to implement your idea, you can

    1. Sell it to them for big bucks, or
    2. Preserve freedom for everyone else by refusing to license it.

  • RFID Patents...current happenings (Score:3, Interesting)

    Last week, Intermec filed suit against Matrics over RFID Patent Infringment. Intermec owns a WIDE variety of patents in the RFID space that are very general in nature.

    For those of you who don't live in the RFID world...Matrics is the vendor who's hardware is being put into WalMart. Many insiders believe that Intermec's lawsuit was designed to poision the water around a possible acquistion of Matrics by one of Intermec's competitors. There is also a general train of thought that Intermec tactically blundered by moving too soon, they should have waited 6 more months for the RFID initiative within WalMart to really catch on before they hit the industry with royalties.

    Good, and very informative article. Can't help but thinking that the guy had his heart and mind in the right place when he invented this. I don't think he envisioned big-brother style monitoring as a use. ..and I also liked the advertising on the side of the blog ("Reach Technologically savvy people"), and how it has anti Bush-Cheney books listed. Apparently those of us who are techno-literate are also anti-Bush...

    I get so sick of people talking about how technology is bad.

    Technology is technology... it is not good or bad. OK?

    Men can use technology in good or bad ways. For example, an axe can chop down a tree or cut someone's head off. It's simply a piece of technology. Scissors can cut paper, they can also be jammed into someone's jugular vein. Nuclear energy provides power for business es and residents everywhere, it also can be used to blow up countries.

    Nothing personal, it's just technology. It's inanimate. It has no feelings. It doesn't care how it might be used. It's just there for use.
    • correct, *but* the fact that this technology exists, that we or other people use / abuse it, means we should enter into reasoned debate about what we consider appropriate and responsible use. To absolve ourselves of any responsibility for the technology we create, and not enter into moral debates over good and bad usage is foolish at best and dangerous at worst. I am sure most slashdotters will have opinions over who should have 'open source' and 'free' access to nuclear weapons technology, for example (USA

    Umpteen morons have posted so far claiming, without benefit of evidence, that RFID has only recently begun to be widely implemented because the patent expired. Baloney!

    Even the briefist of Google searches will show you that RFID implementation has been bogged down by 2 factors: sufficiently cheap manufacturing techniques and industry-wide standards for implementation / data encoding / frequency usage. It took bar codes decades to become ubiquitous, in part because of the same need for standard data dsecriptions that allow every product by every manufacturer to be given a unique bar code.

    See Frontline [frontlinetoday.com], and CSEMag.com [csemag.com], just to pick 2.

    The fact that this was patented had nothing to do with its lack of widespread use. Get a grip, people!
  • To the Walton's of Walmart fame? If so, maybe that explains why they're so into the RFID thing?

    I can sort of imagine taking one to the store, so I can avoid buying clothing that's trackable.

    There's hope for me yet! (And I promise to only use my patents for good.) ;-)
  • Of course I have not read the patent, but the basic idea behind RFID (thump a circuit with RF and it tells you who it is) has been around way longer than that.

    The basic idea is used by IFF (indentify friend or foe) and trnasponder devices used in aircraft. Whack 'em with radar and they output a pattern of radar signals that can be detected and decoded (or even viewed as extra returns on the radr screen)

    I still don't understand how you can base the life of your company on a device that operates under Part15 of the FCC rules.

    Lets say you run a business using a device that runs under part15. Then Joe Joes Auto Wrecker buys a licensed radio system on the same frequency. Your business is shut down with no recourse (SP?).

    This same thing happens with WIFI networks under part15. One day your network is fine, supporting hundreds of users, then one guy with a license moves in the area and your entire company n
