As a specific example of such a scenario -- one that is tantalizingly close to the subject at hand -- look here:

http://www.google.com/patents/US7376184

Read the first paragraph of the description. In layman's terms, it says "even though this patent is being issued in 2008, we claim that it was invented in January of 1992." And with a priority date prior to 1995, this means that they have protection for seventeen years from the date of issuance (i.e., until 2025).

Yes, this means that they have patent protection on this specific technique for 33 years after its invention.

In US courts, this is 100% legal and fully enforceable, since they started the process prior to 1995. And "prior to 1995" is exactly when we're talking about.
