The Company has entered into lease agreements for office space and research facilities in San Diego, California, Rancho Santa Fe, California, Poway, California, Melbourne, Florida, Scottsdale, Arizona, Taipei, Taiwan, Shenzhen and Jiangsu, China, and Cambridgeshire, United Kingdom. Rent expense was $234,085 and $207,696 for the three months ended June 30, 2018 and 2017, respectively, and $467,032 and $391,310 for the six months ended June 30, 2018 and 2017, respectively. The longest lease expires in February 2022. The Company moved into its facility in San Diego, California during the year ended December 31, 2014.

Based on the terms of this landlord incentive and involvement of the Company in the construction process, the leasehold improvements purchased under the landlord incentive were determined to be property of the Company.
