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.
