Copyright Question

When I boot up my PC in the mornings (Windows XP, installed earlier this year) I get the usual start-up screen which includes a copyright notice which says something like “Microsoft © 1995-2001”. Surely this doesn’t mean that the copyright only covers those years, does it?

Thanks

No, I think it means that the authorship of the work took place across an extended period of time.

It means there are multiple copyrights. Some parts of the OS were developed and copyrighted in 1995, some in 1996, etc.

The years are the year the copyright went into effect. Under law, the copyright lasts a set number of years after the copyright date (I believe its 75 years for corporations, but I don’t have my copy of the law handy). So Microsoft holds these copyrights until 2070 at the earliest.

That makes sense - thanks chaps!!

The year should be the year of first publication. See 17 U.S.C. 401

In the US, the term for corporate authors is the shorter of 95 years from publication or 120 years from creation. (17 USC 302©) The term is the same for anonymous & pseudonymous authors and work-for-hires.

Add 95 to 1995 and that’s how long the relevant portions of code are given copyright protection.
