Linux and Unix

Business conglomerates are busily patenting whatever. Browsing the The website of US patent office, one can see that even most common features (drag and drop, copy/paste, spreadsheet, etc.) have been patented. (Even yoga, different types of rice, etc is patented). In the not too distant future, forget RLL, we will be paying royalty to drink water and breath air. No thanks to the patent culture.
