Nature of Operations and Business Activities	1. Nature of Operations and Business Activities Nature of Operations and Basis of Presentation Sorrento Therapeutics, Inc. (NASDAQ: SRNE), together with its subsidiaries (collectively, the “Company”) is a clinical stage biotechnology company focused on delivering clinically meaningful therapies to patients and their families, globally. The Company’s primary focus is to transform cancer into a treatable or chronically manageable disease. The Company also has programs assessing the use of its technologies and products in auto-immune, inflammatory, neurodegenerative, infectious diseases and pain indications with high unmet medical needs. At its core, the Company is an antibody-centric company and leverages its proprietary G-MAB™ library to identify, screen and validate fully human antibodies against high impact oncogenic targets and mutations, immune modulators and intracellular targets. To date, the Company has screened over 100 validated targets and generated a number of fully human antibodies against these targets which are at various stages of preclinical development. These include PD-1, PD-L1, CD38, CD123, CD47, c-MET, VEGFR2, CCR2, OX40, TIGIT and CD137 among others. The Company’s vision is to leverage these antibodies in conjunction with proprietary targeted delivery modalities to generate the next generation of cancer therapeutics. These modalities include proprietary antibody drug conjugates (“ADCs”), bispecific approaches, as well as T-Cell Receptor (“TCR”)-like antibodies. With LA Cell, Inc. (“LA Cell”), the Company’s joint venture with City of Hope, the Company’s objective is to become the global leader in the development of antibodies against intracellular targets such as STAT3, mutant KRAS, MYC, p53 and TAU. Additionally, the Company has acquired and is assessing the regulatory and strategic path forward for its portfolio of late stage biosimilar/biobetter antibodies based on Erbitux^®, Remicade^®, Xolair^®, and Simulect^® as these may represent nearer term commercial opportunities. With each of its programs, the Company aims to tailor its therapies to treat specific stages in the evolution of cancer, from elimination, to equilibrium and escape. In addition, the Company’s objective is to focus on tumors that are resistant to current treatments and where the Company can design focused trials based on a genetic signature or biomarker to ensure patients have the best chance of a durable and significant response. The Company has several immuno-oncology programs that are in or near to entering the clinic. These include cellular therapies, an oncolytic virus and a palliative care program targeted to treat intractable cancer pain. Finally, as part of its global aim to provide a wide range of therapeutic products to meet underserved therapeutic markets, the Company has made investments and developed a separate pain focused franchise which the Company believes will serve to provide short term upside to its core thesis. Through December 31, 2016, the Company had devoted substantially all of its efforts to product development, raising capital and building infrastructure, and had not realized revenues from its planned principal operations. The accompanying consolidated financial statements include the accounts of the Company’s subsidiaries. For consolidated entities where the Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its consolidated statements of operations equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. All intercompany balances and transactions have been eliminated in consolidation.
