High Quality Content by WIKIPEDIA articles! Paperback Software International Ltd. was a software company founded in the 1980s by Adam Osborne, Paperback Software was dedicated to the proposition that computer software cost too much, and that software such as word processors and spreadsheets should be available in the US$20 range. The company was found guilty by a US court of copyright violation for copying the appearance and menu system of Lotus 1-2-3 in its competing spreadsheet program, even though they did use different computer code. The loss of this lawsuit was the main cause for the foundering of the company and paved the way for future copyright law on computer software.
