Key Characteristics & Benefits

This portfolio for sale provides an improved, interactive multi-user virtual reality system that includes a networked virtual world for real time interaction between multiple users. The platform disclosed is machine independent, and allows users with different system configurations to interact with one another as well as with the objects of the virtual world. In conventional systems, users are not permitted to interactively manipulate three-dimensional models of objects in real time. Users within this improved collaborative work environment are able to modify properties of the objects in real time, and these modifications can be permanently stored and re-accessed in the virtual reality system.

The assets in the portfolio have been cited by industry leaders such as IBM, Vivendi, and Sony.

  1. Is this just me, or does this patent pretty much describe any virtual environment, including Second Life and OpenSim?

    •' Nick Zwart says:

      Yes, you are right. Interesting.

    •' Chrisx84 says:

      im sorry but i do not get this post. to me it looks like a scam spam since opensim is fully free to use for residents and others to use to make their own grid and SL and IMVU are free to join and use.

      • No, it’s a real patent, for sale by a real company. The target audience isn’t consumers, but firms that would use this technology as part of their own software.

        The problem is that, from what I can see, the patent is too broad, and covers things that are in common use, from multiple sources.

        Whoever buys this patent could — if they are evil — go out and sue virtual world companies for patent infringement and licensing fees.

    •' Magnuz Binder says:

      This does not affect present OpenSim technology. This patent throughout refers to a world with objects described by executable binary code unique to each object. OpenSim’s object model is one of parameters which is used by common executable code to present the objects.

      •' Ala says:

        Poster ‘Magnuz’ is totally correct. This is in fact a very specific, narrow scope *implementational* patent.

        The assigned inventor (who actually was one of the first people working in VR – totally legit) had come up with a cool way to implement a VR such that it didn’t need to be restarted when new objects were added, which apparently was a problem in 1997. The idea of using machine code blocks as corresponding to individual ‘virtually physical’ objects is an interesting idea in and of itself. It’s actually a pretty good patent.

        However, this is all academic, as modern systems have not been implemented anything like this invention. The “doctrine of equivalents” will not remotely extend the claims to cover current systems. In current systems ‘virtually physical’ objects are represented as data (with perhaps a smidgen of uncompiled scripting code), and there *is no problem to begin with* of having to restart simulation instances to add new items.

        In short, this is a like patent for an assembly of cogs which the portfolio owner is trying to pass off as a patent for an assembly of Lego bricks.

        Not good ammunition for trolling with.

  2.' Doug Maxwell says:

    Patenting something like this is a vacant gesture. There are many different ways to architect a virtual environment. It may have been novel in the 90s, but this technology has become ubiquitous and would be very difficult to patent today without some very specific “special sauce” that makes the approach novel or unique in some way.

    The patent process is (IMHO) broken today. Technology progresses so fast in this field that in the time it takes to protect your IP the technology is already obsolete. Take this image in the article, for example. That’s a generic framework for any distributed multi-user virtual environment. Even if they tried to assert IP rights under that patent, I doubt they could get anywhere.
