The GPS industry has gone through some turbulent times. 

When it was first introduced it was expensive, and it still is.  While traversing the PGA Shows in  years past, the discussion of litigation was a pronounced theme.  Who owned the patents and what the patents covered were subjects of frequent debates.  It was always humorous to hear from  vendors that only they had correct license to operate with the full authority of the patent holder.

The more things change, the more things stay the same.  At the most recent show, we heard that the owner of the patent, Mr. Cornish, was dismayed at the profuse generation of hand-held devices and was filing legal action not only against the long standing GPS vendors but the new vendors as well.

One individual postured that GPS in the golf industry could go “dark” during the legal debates.  It will be interesting to watch it evolve.
