no. although, Microsoft was taken to court over their Windows software, which IBM has used. there was a BIG hullabaloo over MicroSoft's monopolistic business practices over the years, after they would buy out companies, and shut down external competition by changing their code to break competitors' products, then take FREE software, alter it, offer it for free to users, then start charging for it when it became popular.
just look at Microsoft Office, which used to come free with every Windows PC, then started to cost money (currently starting around $200 for the basic package), and now Office 365, which is $100 per year, subscription only...
