- You betcha. There is a number of patented algorithms including
- using XOR for drawing cursor on a bitmapped screen, using backing
- store for saving obscured parts of windows, LZW data compression
- (the thing which is used in compress), RSA public-key encryption,
- elliptical method for solving linear programming problems, the
- "natural" order of recalculation in spreadsheets and others.
- No wonder if someday someone will patent left shift.
