Legalities Question
-
Let's say I was working for a company a year or two ago, and during my tenure there, I came up with a configurable encryption mechanism that involved wrapping a given file with vendor-configurable encryption scheme. This way, the software could only be decrypted by software provided by the vendor, yet regardless of the encryption configuration used. Now, let's say that some software was being written that used this encryption system, but before it could be released, the company in question went out of business. Patent filing was discussed (before the company went under), but as far as I can find, it was never done. I realize there are no lawyers here, but does anyone think I would be violating any copyrights or anything if I were to write an article here about the encryption method I developed? I would be going completely from my memory of the code. BTW, the encryption system wasn't going to work for what they wanted, but they wanted it done, and this was the best I could come up with. The actual encryption mechanism worked great, what they wanted it for prevented other types of security to be used. They were streaming files over the web, and the decrypted files existed as temporary files on the user's hard drive. The company went under before we could try to address this issue (and truthfully, there was no fix for this issue due to extenuating circumstances).

I found this text on the net regarding US laws: Fair Use. Even with that in mind, there are further limits to copyright. For example, partial or limited reproduction of another's work may be permitted under the doctrine of fair use. This doctrine is especially liberal where the use advances public interests such as education or scholarship and specifically permits making a backup copy of a program. Further, sellers of utility software, such as clip art or programming libraries, should permit hassle-free distribution of non-competing works created by licensed users. [Programmers should seriously consider whether to use the work of publishers who assert additional rights.] Beyond fair use, still more fundamental limits to copyright protection should be considered. Expressions are Protected, not Facts or Ideas. The basic idea is easily illustrated: An author of an online story has protection for her words, but not for facts that she went to the trouble to collect or her basic plot. Similarly, a programmer has protection from others' duplicating a segment of code but not from their writing different code to accomplish the same end. Protection for facts as such is probably not available, and processes can be protected, if at all, only by trade secrets or patents. [For more on the last option in particular, see Seeking Cost-Effective Patents, right-hand navigation bar.] That said, caution is nevertheless warranted. Copying someone's creative presentation of facts could easily infringe. Also, merely translating from one language into another may infringe -- just as would translating a novel from French to English. Independent Creation is Permitted. A second work, identical to an earlier copyrighted work, does not infringe, if it is, in fact, independently created. While a well-known first work of a very unique or fanciful kind may make an independent creation defense difficult to believe, the problem may be more complicated with regard to some kinds of software. Assume that, code has been copied with slight variations from the original, and it is claimed that function dictated form. A practical cure for the problem of showing that a work was in fact copied is to embed "identifiers" such as misspellings and useless loops or variables. The objective is to hide them so that they will show up in copies which are claimed to be, but are not, independently created. If so, the issue will no longer be the alleged copier's credibility.

Fair Use - does not apply. Independent Creation - does not apply. You are not independent to the original creation. An example of this is AMD creating x86 processors that duplicated Intel's functionality. AMD had to go out of their way to find engineers with no prior knowledge of Intel's chip designs. Expressions are Protected, not Facts or Ideas - This should cover what you want to do. As long as you are rewriting from scratch, with no reference to the original code, you should be ok. However, you should get legal advice ... blah blah blah.

"Many : not conversant with mathematical studies, imagine that because it [the Analytical Engine] is to give results in numerical notation, its processes must consequently be arithmetical, numerical, rather than algebraical and analytical. This is an error. The engine can arrange and combine numerical quantities as if they were letters or any other general symbols; and it fact it might bring out its results in algebraical notation, were provisions made accordingly."

"The staggering layers of obscenity in your statement make it a work of art on so many levels." - J. Jystad, 2001If the company folded without unpaid debts, you might be OK, but if debts were traded or otherwise still exist, then the "owners" of the debts will likely come after you. And if you're thinking about "doing it a little bit different", don't. Even though it was your intellect that created the software, it is not your intellectual property, and, in reproducing it, you will be using the company's intellectual property (i.e. your intellect at the time when you originally wrote it). Have a lawyer find out the debt situation. If there are no creditors still using the company's debts as assets, then it's unlikely that there will be any trouble.

That's copyright law, not patent or intellectual copyright law. If you had written a story, and decided to write a similar story later, the codicils you cite would apply, but they don't apply to software. What you're talking about is writing an article that can be used by anyone in the world to illegally reproduce a product that is legally owned by someone else. Maybe you should put it on Rapisdshare, not CP.

Jystad, 2001In my opinion, if the company went bust then it still has assets which can be redeemed by a liquidator, administrator or whoever. One of those assets would be its intellectual property and this could have anything from signiciant to little commercial value - on the other hand it would have little value if it was revealed in a CP article. I presume while you worked there you had some contract of employment and undertakings about the companies IP which you might breach if you wrote an article revealing the thinking etc. Just my tuppence worth

The legal issue is not of the code but of technique. The code might be different but the technique might be same, so that will be a problem.
FYI: Techniques cannot be copyrighted. They can be patented.

That leaves me, more confused. :) I guess if your company complains or sends lawyers after you, you can always remove the article.

"The staggering layers of obscenity in your statement make it a work of art on so many levels." - J. Jystad, 2001If you want to do more than write an article about it - make some money, maybe - then why not buy the rights off the company receivers? Something along the lines of "Hey, dude, I wrote some stuff for XYZ company which never worked and looked like it never would but I'd like to try something new on it, can I buy the rights to it for some small sum of money?" Finding realisable assets in a software bankruptcy is hard, they might take some cash and clear you away legally.

You would need specific legal advice, but a general rule of thumb is all things done whilst you were employed by the company belong to that company unless explicitly stated otherwise. Even if the company has folded, this would still be seen as an asset for administrative purposes. I write as an accountant, not a lawyer. If there were debts owed when this company crashed, then this software may be sold/licenced to cover these debts, the liquidators would ensure all assets were realised efficiently. Alternatively, you could write something 'similar' but not close enough to be infringing, (look and feel), and that may be ok. As I say, take professional advice on this.

Dalek Dave has pretty much nailed the legal aspects. The company did not patent the concept which would have protected the idea regardless of how it is expressed (assuming a patent could be granted). Therefore the only existing IP consists of a copyright. Copyrights apply to the expression of an idea, not the idea itself. Therefore one could (most likely) express the same idea in a different format legally. The "most likely" qualifier is because the courts have not been consistent in interpreting how different the format has to be. A photo of a painting is clearly different from the painting itself. A movie is clearly different from a book. But is a program written in C different from one written in C++ if they are otherwise identical? Now consider the practical aspects; If the company is truly defunct and there is no successor owners, than your exposure is minimal. Especially if there is no patent, since any successor will probably not be familiar with the copyrightable specifics of your prior efforts. From a practical stand point a successor is very unlikely to pursue any action against you since they would need to become aware of 1) your prior efforts on and 2) your current efforts. Not very likely in the aftermath of a failed company. Assuming they did claim an infringement, the most they can pursue is a copyright infringement and even that would be questionable provided you don't lift the code directly. I would say re-write it and go for it.
