I have that CD, and while the description I bid on said there were no copyright issues, many of the scans do have copyrighted patterns, indicated by the symbol and date, or written out on the pattern drawings.
Be aware that all the patterns pre-date rotary cutters and strip piecing methods, so be prepared to make templates and add seam allowances to them. Many of them have little, if any, real instructions, so they may be hard to figure out for some quilters. Block sizes vary considerably, and some patterns do not list finished size at all.
They are fun to look through as a bit of history, though.
