Sorry to say, this is the case. If you look around the clinical lab you will find dozens of examples of patented procedures. Histology is just now feeling that pinch. The best example is PCR. It is a patented procedure and certain reagents are only available as part of a patented kit.

There was a long discussion on tyramide on the Histonet last year and the person who invented it got in on the discussion. The main problem he was concerned with was people who promoted circumventing the patent by telling people how to get around it. That is a big no-no.
