I liked working for DWS, they where a small and quirky company with good people. DWS/SDC never sued anybody for this patent, it was mainly a bargaining chip to impress clients. Mind the patent is about DRM, specifically, it's about polymorphic DRM (that is the variant that delivers its own encryption/decryption/obfuscation code together with the content).
Sidenote: DWS/SDC where far flung leftovers of Napster.
But then the inevitable happened, the companies got bought by PacketVideo. The founder/investor and the then CEO (a superb business drummer, though no techie) left the company and American management took over.
During my work there, I was increasingly troubled by the DRM side of business. Eventually I left (and I'd have probably been fired if I didn't), mostly for reasons where management differed with my idea of efficiency and quality. I traveled around the world and I started freelancing, and I can't say it was a bad decision, has been a good life since.
I'm not surprised that PacketVideo eventually started suing people for the patents they hold. It's a small and troubled company that's been struggling for years to "get it right", and as they probably increasingly run out of funds to keep the fiction alive, it gets ever more tempting to cash in some quick buck simply by virtue of sitting on patents you've acquired.
Shooting down incoming projectiles? Good luck if the first shot misses, since you'll probably have to wait minutes for the capacitor to reload. And there's probably just one unit per ship because you'd need a nuclear reactor to power it.
Shooting at other ships? You need lasers for somali pirates, really? Oh, I see, you want to shoot at other seagoing warships with that? Good luck with that, since your run off the mill modern naval warfare is a "behind the horizon" kind of affair, I wanna see that laser shoot trough the horizon...
You want to shoot at submarines with that? (dude, I won't even go there with whats wrong trying to shoot a laser trough a randomly refracting barrier into a really light absorbing medium).
You want to shoot down satellites? Sure, you could do it with that, though, why do you need a laser on a *ship* for that? You know, satellites, they go round-n-round the earth, just wait until you have it in your sights...
Shoot at targets on land? I don't know if you've heard this, but there's a thing called "coast" and a thing called "curvature of earth", and absolutely most fat&juicy targets on land try to squat in inaccessible hilly or mountainous terrain, far, far inland. So, I want to see that thing shoot trough a horizon made of dozens of kilometers of solid rock.
Really, it's bloddy useless, unless you need to compare dick sizes with whatever other military feels compelled to do that. I hope it helps your self esteem dear US navy.
Saying Phong is right after fitting the calculated data to the measured data just suspect.
