Copyrights for closed business
I would like to teach a class using a pattern that I purchased many, many years ago. In researching the company and pattern for class members to purchase, I cannot find them! I have exhausted all my resources to find them. My assumption is that the creators of the pattern have gone out of business and the pattern is out of print. It was copyrighted in 1995.
Does the copyright law still apply? Can I photocopy the pattern for my class?
Thanks for your thoughts on this.
