June 28, 1990: Paperback Software is found guilty of copyright infringement

A federal court ruled June 28, 1990, in the case of Lotus v. Paperback Software, finding Paperback Software guilty of copyright infringement of the Lotus 1-2-3 spreadsheet program. The program in question was the VP-Planner spreadsheet by Paperback Software, which was designed to work exactly like Lotus 1-2-3. Paperback Software claimed the Lotus program was not eligible to be protected by copyright laws and that standardizing such as program was in the best interest of the technological community.
