update June 20, 1996 ----------------------------------

Further to our March 1, 1996 e-mail sent to IESG members, we
have to now inform you, regarding the U. S. patent application
Serial No. 08/014,766, that a U. S. Patent No. 5,517,618 was
issued on May 14, 1996.

We have carefully reviewed, with members specialized in
intellectual property, the relevance of the U. S. Patent to
the Mobile IP draft, or the "IP Mobility Support" draft.
As a result, we concluded that 1) the U. S. Patent discloses
our ideas from which the "IP Mobility Support" draft could
be derived, but 2) claims of the U. S. Patent would not be
broad enough to fully cover the "IP Mobility Support" draft.

On the other hand, we have reviewed also our other related
patent applications, and confirmed that the following
pending patent applications would cover the "IP Mobility
Support" draft.

- a U. S. divisional patent application of the above U. S.
Patent, which includes claims that would be broad enough
to cover the "IP Mobility Support" draft
- a European patent application of publication No. 0 556 012 A2,
which is a corresponding European application of the above
U. S. Patent
- Japanese patent applications No. 05-227161, No. 06-095998,
No. 06-149689, which are priority applications of the
above U. S. Patent
- a Japanese patent application of laid-open No. 05-83260

B. Does this disclosure relate to an unpublished pending patent application?:

Has patent pending
