how can ( if can ) one protect her/his LO Calc document ( spreadsheet ) with

What is the preferred way to eg.: share a Calc document, but protecting it
from expropriate?

Or is it sufficient to protect a Calc document with a password?

You set a password for opening a document and another for editting. You need to set them when saving the document. For a limited distribution document this is probably adequate. You then need to distribute the passwords. In theory you know who has access and thus could be the source of any misuse.

If you want the document to be readily accessible, read-only there is a risk for someone to expropriate your work.

If you take a printed copy and a CD copy of the spreadsheet. Add all of the documentation about how, and when you made it. Then mail it to yourself. Make sure it is sealed very, very well, so no one could say you placed the stuff in the envelope at a later date.

When you get it in the mail, do not open it. Give it to your lawyer inside another envelope with the same printer and CD copies and all the documentation.

The sealed mailing will show a postal date. That gives you a time line showing you developed it as late as such and such date. Giving it to a lawyer, or having the lawyer mail it to you can help with some later legal issues that may come up. Make sure you get input from a lawyer as soon in the process as possible.

That is the cheapest way of proving you came up with the "idea". But, you need more, I think. You want people to use the sheet but not steal the code, right?

That is a different issue.

Copyright and licensing a "set of code" can be different in many ways on how to protect you rights. You should do the "simple protection" of the mailing to start and then get involved with a copyright lawyer. Next is the "securing" of you spread sheet "codes" and macros. That could be done in some cases with password protections to stop people from editing, or listing out, all of the cell contents and the macros involved. Some type of "execute only" option is needed. Also, having the only the cells that need to be changeable be able to be edited is a good idea.

How a spread sheet can do all of this.?. . . Well, I would have made a program and compiled it and had it run just like the spreadsheet would for showing the rows and columns. That is one of the only ways I could make sure my work not get its internal "coding" available for others to read, copy, etc..

Now the question a lawyer would ask. . . What are you going to licensing and for want purpose. Are you going to allow users to download the file and require them to pay you for a key or password to allow it to run? Or are you going to license the intellectual property of the coding of the cells and macros? Will you hold the copyright or the "code base" and allow others to use it or are you wanting to keep others from seeing what you have created but have a way to use it.

There are a lot of things you need to ask yourself and these are just some of the things I remember a lawyer asking me when I created an item I wanted to protect as my intellectual property and stop others from claiming it was theirs.
