What a strange criticism of Microsoft! Here is something to know about
patents: many companies file patents all the time. That doesn't mean
they are committing to build a product around every patent they file.
The fact that Microsoft hasn't pursued patent 5,768,385 tells you
essentially nothing about what they are going to do with this patent.
I wouldn't take patent filings as an indicator of intent or of future
business strategy.
