{{main|Look and Feel}}
Lotus was involved in several lawsuits, of which the most significant was the "[[look and feel]]" cases which started in 1987. Lotus sued [[Paperback Software International|Paperback Software]] and Mosaic for copyright infringement, false and misleading advertising, and [[unfair competition]] over their low-cost clones of 1-2-3, VP Planner and Twin, and sued [[Borland]] over its Quattro spreadsheet. This led [[Richard Stallman]], founder of the [[Free Software Foundation]], to found the [[League for Programming Freedom]] (LPF) and hold protests outside Lotus Development offices.<ref name=NewsW>{{cite magazine
