US application 06/078,118, was granted as US4378187A on 01-26-1983. Since this is before 1995, the term of the patent would be 17 years from the grant date which results in an expiration date of 01-26-2000. As such, the patent has expired. I don't know of any provision that allows a patent to extend beyond its expiration date, especially one which should have expired so long ago.

I am not a lawyer and this is not a legal opinion.
