You're going to have to contact a patent lawyer for specific legal advice. None of us here are probably qualified to provide such, and certainly not on a public forum.
Reading my own response a year ago to your similar question (which you kindly copied here again) reminds me of how much I've already forgotten about the apparent soap opera history of patents and disputes in the VR imaging arena. The bottom line is that nobody's apparently made much money from any of these patents, nor has the VR imaging community seem to have benefitted much from all these patent claims. A number of the individuals and companies holding these patents have gone out of business. Others seem to have done little, if anything, with their intellectual property. Even while you were the QuickTime manager at Apple, Apple was filing its own spherical/cubic panorama imaging patents (so you may already know a lot more than the rest of us about all this), yet this is technology that Apple hardly even supports any more.
The good news (I guess) is that some of the early patents in this area have reached, or are reaching shortly, their expiration dates. Prior to 1995, most U.S. patents were for 17 years. In 1995, this was changed to 20 years. So a VR patent filed in 1994 would be expiring in 2011 -- or next year.
And as far as determining the validity of a questionable patent (such as some of those described in this forum in previous discussions), that unfortunately has to take place in a court of law (as the result of a lawsuit) once the patent has been granted by the USPTO. So if you want to challenge whether a patent applies to technology you might be using (or considering), you should probably have the resources committed to pursue it in a court of law.
But again, I am neither an attorney nor an expert in this area, so my comments are likely invalid and are in no way to be considered legal advice.

Great summary Scott!
I have a question about the actual patent. Before I read all 20 or so pages of this patent I was hoping one of you would know what exactly we as photographers/VR developers can do and not infringe on this patent.
My understanding is the patent describes capturing 2 images using a circular fisheye lens. If we capture more than 2 then we are not infringing on the patent.
Is that correct?
