This is funny. A few months back, an old co-worker of mine at Lockheed-Martin sent me a quote from a mailing list of simulation engineers that do operation research for the DoD. In the email, a guy from one of the commercial research labs was saying that they had received a letter from a game company claiming that they and all other research labs doing DIS and HLA simulation work for the DoD were in violation of their latency patents and wanted money from them. The consensus was that these guys had a screw loose. The consensus was that this patent (which was in Dale’s name but I’m certain that it was IEN rattling the sabers) was little more than fairly obvious derivations of much earlier published works like DIS that have been around for decades. So, they were putting out a request for gathering up documentation to slap these guys down with, including input from the lead engineer who worked on the original DIS implementation. I never did hear anything more about it so I guess they sweety-slapped who ever it was back into place.
With no disrespect intended towards HT, if you’re willing to pay a lawyer, you can get almost ANYTHING patented. Now whether the patent is actually defendable in a court challenge is a whole ‘nother ballgame.
