         for such product in such country, or a specified number of years after
the first commercial
         sale of such product in such country. Please revise your description
of this agreement to
         clarify when the royalty term ends.
Competition, page 142

3.       We note your response to prior comment 4. To the extent that you are
aware of certain
         patents owned or controlled by potential competitors with claims that
could be construed
         to cover certain of your product candidates, please tell us why the
identification of the
         specific patents and patent applications as well as their
holders/applicants would not be
         material to an investment decision.
5. Revenue, Other Income and Gains, page F-29

4.       With regard to your response to comment 6, please revise the
disclosure as necessary to
         more clearly explain that there were two payments and:
           clarify that the U.S. right-to-use license amount of $22.2 million
was recognized in
             2017 by Legend USA and the non-U.S. territories license amount of
$7.6 million was
             recognized in 2018 by Legend Ireland; and
           clarify that development services are included within the obligation
that is currently
             labeled "joint steering committee" as you state in your response
"it was determined
             that the largest portion of transaction price should be allocated
to the JSC services as
             the Company is responsible for a significant portion of the
development work prior to
             commercialization". Labelling the obligation as "joint steering
committee" appears
             to be too narrow.
20. Contract Liabilities, page F-42

5.       In order to avoid confusion, please include your response to comment 7
in the disclosure
         to clarify that:
           the $204.4 million balance of contract liabilities at January 1,
2018 represented the
              amount of $227.5 million to be paid by Janssen to Legend USA less
the license
              revenue and JSC service revenue of $23.1 million recognized in
2017;
           the $227.5 million was received in January 2018;
           the remaining $122.5 million of the $350 million upfront payment
became due in
              2018 when Legend Ireland, owner of the non-U.S. license, began
its collaboration
              with Janssen in 2018; and
           the $122.5 million was received in March 2018.

        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
