-Patent examples in telecommunications.(20mins)

here's a novel idea: let's take a look at the patent in question (US 5,625,670) and see what is actually says...

first, look at the filing history (on the first page of the patent)

This application is a Continuation application of U.S. Ser. No. 07/702,939, filed May 20, 1991, now U.S. Pat. No. 5,436,960; Ser. No. 07/702,938, filed May 20, 1991, now U.S. Pat. No. 5,479,472, and Ser. No. 08/247,466, filed May 23, 1994, now U.S. Pat. No. 5,938,611; which is a Continuation of U.S. Ser. No. 07/702,319, filed May 20, 1991 (now abandoned).
