You can guess who is behind this patent application.

I think some patents awards have gone way out of line. Given the capabilities in many applications, sometimes a little ingenuity and sometimes hard work are all it will take to make a program give results not envisioned by the app maker nor expected possble by the app's competitor. If an app can be made to create rail sweeps and helixes (helices?), then it's not all that far away that someone could create a script (or, by old-fashioned pen and paper) calculated the appropriate iterations needed.

Anyway, nevermind my drivel... read the patent application...

But, also check these out, too:

I agree with regards to some software patents that have been granted. Interestingly, the PTO may be changing it's position on software patents which is rather significant especially with its "physical transformation" requirement.

This link gives a pretty good overview of the situation.

Remember when during the dot.com craze businesses were applying for and receiving patents on business processes, sometimes being jazzed-up processes that one could learn in college, or apply through practicality or common sense or just following others in the industry. That kind of patent would scare the bejeezus out of anyone trying to go into business having established, deep-pocket competitors.

That might be part of why i grouse when some CAD software firms don't enable multi-character, user-definable shortcuts. I keep having this nauseating feeling that somehow Autodesk either got a patent on it, or has lawyers constantly dialing into any CAD firms that say they might add such capability, even if it is an overlay to or an API call into an existing, functionally-limited product.

Cheers!

I use ViaCAD alongside TurboCAD Pro, which has some stair generation ability already, and I'd taken it for granted that Revit would've already included some. I assume Punch's home design software does it, too. Can a fresh Autodesk patent really be granted for associative recognition of an imported sketch, because all the application really says is that at step 430, arbitrary elements can override a parametric stairset! If a patent application is covering something that's a development of something already in use, it's supposed to be knocked back on the basis that it would "be apparent to someone skilled in the art", and IP law supposedly excludes the possibility of patenting something that's already in the public arena. Autodesk's application looks like an ambit claim to try and corral any user-input-override to parametric capability that might be applied to stairs. Most parametric applications would be capable of stair generation if you turned them to it, so Autodesk is saying that the ability to custom build over a parametric basis is their's alone! Quite a few TC users complain that they have to do so already, but Autodesk's is novel and innovative because it permits you to? I suppose it's worth feeding a few lawyers if they can score a patent monopoly for an existing field that they didn't even establish.
The USPTO's new stance brings it closer to the UK government's point of view. Historically, they've been opposed to software patents in principle.

Thanks for the heads up, Tim. Gotta rush off and offload some Google stock!
