Patent 5,579,517 mentions a couple of articles from PC Magazine on "long file names and extended attributes" that were published in April and May of 1990. They were written by one of the patent authors, Ray Duncan. However, the initial patent application was not filed until April 1, 1993. I was under the impression you only had a year to file from the date of the initial publication of the details of your patent claims. Perhaps, the extensions mentioned in the PC Magazine articles are substantially different from what's in the patent claims. However, it would seem to be worthwhile to look up these articles. I wonder if the patent examiner even bothered to do this?
