Sony Sued for Blu-Ray Patent Violation 153

Posted by Zonk from the how-shiny-is-too-shiny dept.
Jaidan writes "According to a Gamespot article, a California-based company named Target Technology is suing Sony over patents it allegedly holds for silver based reflective surfaces. The suit claims that products marketed under the Blu-ray name infringe on a patent it owns for reflective layer materials in optical discs. Target is seeking a permanent injunction preventing Sony from violating its patent rights in the future, as well as damages with interest, multiplied due to what it characterizes as deliberate and willful infringement. ' The patent addresses what Target called a need for specific types of silver-based alloys with the advantages (but not the price) of gold. According to the patent, the alloys are also more resistant to corrosion than pure silver. Target does not specify in its suit whether it believes all of Sony's Blu-ray discs infringe on its patent, or the suit applies to just a portion of the discs manufactured. The patent was filed in April of 2004 and granted in March of 2006.'"

I know that Blu-ray has been in development for quite a time and the specifications were announced in the year of 2004. If Sony can provide sufficient evidence in court that what is claimed by Target had already been conceived in some form by them they will be able to circumvent this lawsuit and nullify the patent.

      Why is this a bogus patent?
      The key is that it might be a bogus patent. I've linked the patent [uspto.gov] in another post I made, but here's the summary:

      A silver-based alloy thin film is provided for the highly reflective or semi-reflective coating layer of optical discs. Elements that can be added to silver to produce useful silver alloys include zinc, aluminum, copper, manganese, germanium, yttrium, bismuth, scandium, and cobalt. These alloys have moderate to high reflectivity and reasonable corrosion resistance in the ambient environment.
      Ok, so if I get a patent that says "silver alloys are best for reflective surfaces" and then I go on to list the possibility of using all elements in the periodic table (or those that make sense) and then I get that patent ... basically no one else can use silver in an alloy to make reflective products. Does that seem right? Should you be able to patent an alloy? Should you be able to blanket patent alloys that are reflective and restrict their use to your 'idea'? Isn't that something mother nature made possible? I'm not a chemist, is this stuff common sense? I think that a lot needs to be analyzed before this can be an obvious or bogus patent but, you know, there are a lot of reasons this could be a bogus patent.

      Personally, I think patents should be "if you don't use it, you lose it" because what good does it do us if an idea is patented and the company just sits around waiting for a larger one to use it? The patent system is broken and so is the mentality of about half the patent holders that use it. It's no longer about protecting your intellectual property, it's about the tricks you can play to get insane sums of money. How long did NTP wait for RIM to expand and grow? A long time. It's not currently wrong but morally they've gotta be approaching some sort of evil.

      Patenting technology [e.g. material sciences] is not the same as software. In software, you're more likely to just adapt from a known source to suit your needs. True innovative [and original] computer algorithms are rare, which is why people oppose software patents. If it were the case that truly original innovations were common in software it would be a different story.

      As for material sciences [e.g. making a disc] it could quite possibly not have been obvious that a given composition of alloys make a highly reflective corrosion resistant material. Just because something is computer related doesn't mean it's software. Of course, just because you got a patent for it doesn't mean you deserved it too...

    I haven't read all the patents referenced by Target Technology Company's patent but if they have a case, this looks like TTC built a slight logical advancement on top of Sony's (and a vast number of other company's) work in optical discs and optical drives then they waited for someone to make this logical step. Here, it looks to be using a certain chemical to make the discs more reflective. Ok, so maybe they spent a lot of research and maybe they didn't ... I don't know. Is it a specific chemical? Could one patent the specific use of a chemical? Did Sony just read the patent and use the chemical? I'm sure the court case will have to examine all that. I just hope some kind of justice can be found that seems right and logical in this case between the two companies.

    But this looks like I could draft up a generic patent about triple layering and/or quadruple layering of data on discs and apply for the patents then just sit back and wait for someone to try and use it. I would reference all the dual layering patents and all that jazz. Would you call my ideas innovative or just common sense? Would it seem right that I didn't even have to implement these solutions? I don't know, I can think of instances where one could argue either way and this is what is inherently wrong with the patent system. Of course, I don't know how to fix it but I don't like how it works right now.

    • After reading, this patent doesn't seem to be an "invention" at all, but rather a research paper which shows which alloys work best.

      While I personally don't think you should be able to patent a discovery, I don't know how the current legal system of any country handles these.

      Note that there's a subtle and probably subjective difference between trial-and-error for finding an alloy, and specifically tailoring an alloy for some purpose, and I've a bad feeling that's what applies here.

The patent system should serve to make it more likely that Edison style filament experimentation will occur. If the sort of invention/discovery is not of that kind then it's of dubious value to grant a patent for it.

            I disagree. I think if you come up with anything, purposeful or accidental, you should be able to patent it (so long as it meets the other criteria). HOWEVER, in today's industrial/economical environment, patents should be much shorter.

Even if the patent issued, anyone you accuse of infringing the patent would hire experts to say that you did not possess the invention at the time you filed the patent application, and that you didn't describe the invention sufficiently. This requirement of enablement and written description is in addition to the requirement that the patent not be obvious, or anticipated b

    There isn't enough information here to form an intelligent position.

    Given that Target is only suing Sony over Blu-Ray, and not suing any other organizations over CDs, DVDs, GD-ROMs, Game Discs, HD-DVDs, or FMD-ROMs (!), it's possible (however unlikely) that this is actually an example of patents working the way they should. That is, Target may have a patent on an actual technology; a specific method of producing a reflective layer that is superior and/or cheaper than other methods. If that's the case, then this is exactly how patents are supposed to work.

    Alternatively, of course, Target may have patented an obvious evolution of well-established technologies, in which case this is just another patent troll. They could be holding off on suing other companies until they've set some sort of precedent with Sony.

    The actual patent [uspto.gov] begins by specifying an alloy of silver an yttrium, but the further claims also (apparently) expand that claim by including alloys with other elements (such as bismuth and tin). I don't have the time right now to examine the patent in great detail; but a skim makes it look like they patented a specific method for a high-reflectivity layer thats cheaper than other methods of equivalent reflectivity. They then expand this idea to include all the derivative technologies of using this method (single & dual layer discs, write-only discs, write-once disc, re-writeable discs, etc).

    The problem is I don't have enough familiarity with the technology to know if this is a non-obvious development or not. If it is non-obvious, then more power to them. Protecting your novel idea with a patent is fair play. If, of course, it's just the optical disc equivalent of "[X], but on the INTERNET and called i[X]," then I hope they get counter-sued into oblivion.

    After doing a little looking at thier site, Target Technology gets their name because they do actually make products with this technology. The make silver alloy targets for sputtering the metal onto optical discs, and their targets are currently used manufacture of many DVD-R's and other optical discs. I would guess (though I don't have enough information to be sure) that they think Sony looked at the compostion of their targets, said "hey, these work really well," and decided to make their own targets of the same compesition for their Blu-ray discs. True or not, I have no idea, but it is at least possible a valid patent case. It's not like this is just an company who hoards patents and licenses them, they actually make products based off of those patents.
  • It's a marketing scheme. Sony and Target are in it together to create a buy-the-PS3-now-before-production-must-cease frenzy. Since there are thousands of PS3s sitting on store shelves collecting dust, this would seem to be the best method at resolving the problem in a hurry. Then as soon as the overstock problem is resolved, Sony and Target mysteriously settle on undisclosed terms.

  • This patent is not a submarine patent. This patent took 2 years to go from first application to being granted, which is pretty standard. There are a lot of steps and paperwork involved, especially if you have to edit your claims (and this patent had to be revised a couple of times when it was issued two non-final rejections -- again, this is pretty standard). Just search the USPTO legal status [uspto.gov] of this patent (7018696) to see.
