FWIW - it's widely believed (a belief CMW continues to promote) that 'the' D-shaped port for Porsche (probably just 911, haven't actually read the patent...) cylinder heads is patented.
Article on CMW's D-Port Patent Clearly there are forms of automotive industrial design that are protected and protectable. Software duplication, CNC/CAM part cloning, and other intellectual ripoff techniques are just very poor form, practiced by the greedy and lazy. |

Clearly there are forms of automotive industrial design that are protected and protectable. Absolutely. But they're real innovations that "advance the art", meaning different and unique ways of doing things, and not subtle modifications of existing methods. Part of the "art" of getting a patent is convincing the examiner that what you're doing really advances the art. Subtly re-shaping a port wouldn't, while totally re-forming it into a D? Maybe? Evidently. Edit: Funny, after writing that I went to the CB Performance site, because they used to sell a "mini-D" port head. It's not there, the port is extended a bit more and they're now called "wedge" ports. But a web search turns up hundreds of other "d-port" heads, modified and new, from lots of big companies. Evidently Pontiac was making "d-port" heads back in the Sixties. So that CMW patent may not cover what they represent it as covering, another little trick about "patented" products. And yes, Andy, you're right. I was referring to patent related intellectual property and not thinking about other types. But if you just went through this then I'm sure your lawyer told you about good practice, always using that copyright phrase and using the TM symbol whenever you use a proprietary term. Those give you protection later if there's any doubt about origination. With mechanical innovations that good practice is a patent. If you don't have it, and if the item's been in commerce for a year without it, then it becomes public knowledge and there's no real protection. Jake doesn't have a patent, or a patentable product, so this is really all about business ethics. Someone is rumored to be thinking about copying Len's good work. But head porting has always been art mixed with science. A CNC machine can get close, but like Len observed, it can't do it all. This is when good reputation counts. |
