Do they have "the formula"? - I assume everyone is referring to the patents. As detailed as they may be, they have some caveats of their own in the language. You dont think they would give it all away in something they knew would be publicly accessed do you? C'mon now. The wording I am referring to by the way straight from the patent is:
Persons of ordinary skill in the art will realize that the following description of the present invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons.
AND
While embodiments and applications of this invention have been shown and described, it would be apparent to those skilled in the art that many more modifications than mentioned above are possible without departing from the inventive concepts herein. The invention, therefore, is not to be restricted except in the spirit of the appended claims.
I am not an expert in patents, but the attorneys who draft them are, see below:
According to a recent court decision, the short answer is “no” if all elements of the trade secret are disclosed in the patent application. However, the decision also notes that certain elements of an invention — such as improvements, elements that are not expressly disclosed in the application, and unique combinations of previously-disclosed elements – can be protected by trade secret law.
Anyway, it gets complicated beyond that, but I jsut wanted to point out the formula to make it in my opinion is not all there in the patent to be able to just create it at will. Thanks,
