Presentation and Summary of Significant Accounting Policies	NOTE 2. PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial statements and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not contain all information and footnotes required by GAAP for annual financial statements. Such unaudited condensed consolidated financial statements and accompanying notes are the representations of the Company’s management, who is responsible for their integrity and objectivity. The information included in this Form 10-Q 10-K The accompanying condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which are normal and recurring, necessary to fairly state its financial position, results of operations and cash flows. All significant intercompany transactions have been eliminated in consolidation. The financial data and the other information disclosed in these notes to the condensed consolidated financial statements reflected in the three and six month periods presented are unaudited. The December 31, 2017 balance sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements. Use of Accounting Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the accompanying condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The principal estimates relate to revenue recognition, allowance for doubtful accounts, and the valuation of stock awards and stock warrants. Actual results could differ from those estimates. Significant Accounting Policies Beginning in the first quarter of 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. There were no other material changes in the Company’s significant accounting policies from those disclosed in its Annual Report on Form 10-K Reclassifications Certain reclassifications have been made to prior year amounts for consistency and to enhance comparability with the current year’s financial statements presentation. There was no impact on total assets, total stockholders’ equity, accumulated deficit, or net loss resulting from these reclassifications. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) 2014-09”), 2014-09 2014-09: No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations 2016-08”); No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing 2016-10”); No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients 2016-12”), In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) right-of-use right-of-use In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force) In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting

Significant Customers And Concentrations Of Credit Risk	NOTE 4. SIGNIFICANT CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK The Company’s ten largest customers by revenue accounted for approximately 49.7% and 52.1% of its net revenues in the three and six months ended June 30, 2018, respectively. The Company’s ten largest customers by revenue accounted for approximately 65.7% and 67.2% of its net revenues in the three and six months ended June 30, 2017, respectively. The Company is potentially subject to concentrations of credit risk through its financial instruments, which consist primarily of cash and cash equivalents, marketable securities and accounts receivable. The Company limits its exposure to credit loss by placing its cash with high credit quality financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company typically invests in highly-rated securities, and its investment policy generally limits the amounts that may be invested with any one issuer. The policy generally requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss.

Financial Instruments	NOTE 5. FINANCIAL INSTRUMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy, which is based on three levels of inputs, the first two of which are considered observable and the last unobservable, that may be used to measure fair value, is as follows: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2—inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or • Level 3—unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company classifies its financial instruments within Level 1 or Level 2 of the fair value hierarchy on the basis of valuations using quoted market prices or alternate pricing sources and models utilizing market observable inputs, respectively. The Company’s money market funds are valued based on quoted prices for the specific securities in an active market and are therefore classified as Level 1. The Company’s government securities, commercial paper and corporate debt securities are valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. As of June 30, 2018, the Company has not made any adjustments to the prices obtained from its third-party pricing providers. Cash and Cash Equivalents and Marketable Securities The Company’s money market funds and marketable securities are categorized as Level 1 and 2, respectively, within the fair value hierarchy. The following table shows the cost, gross unrealized losses and fair value, with a breakdown by significant investment category, of the Company’s cash and cash equivalents and marketable securities as of June 30, 2018: Cost Gross Fair Cash and Marketable Cash $ 11,034 $ — $ 11,034 $ 11,034 $ — Level 1: Money market funds 41,658 — 41,658 41,658 — Level 2: U.S. government securities 4,501 (13 ) 4,488 — 4,488 Commercial paper 997 (2 ) 995 — 995 Corporate debt securities 20,164 (121 ) 20,043 — 20,043 Subtotal 25,662 (136 ) 25,526 — 25,526 Total $ 78,354 $ (136 ) $ 78,218 $ 52,692 $ 25,526 As of June 30, 2018, the Company held securities with an aggregate fair value of $25.5 million that were in an unrealized loss position for less than 12 months. No securities have been in unrealized loss positions for greater than 12 months. Gross unrealized losses at June 30, 2018 represented temporary impairments on government securities, commercial paper and corporate debt securities related to multiple issuers and were primarily caused by fluctuations in U.S. interest rates. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and duration management. As of June 30, 2018, the Company considered the declines in market value of its marketable securities to be temporary in nature. All of the Company’s marketable securities were due within 2 years of June 30, 2018. As of December 31, 2017, the Company’s cash and cash equivalents and marketable securities balances were as follows: Cost Gross Fair Cash and Marketable Cash $ 8,925 $ — $ 8,925 $ 8,925 $ — Level 1: Money market funds 20,620 — 20,620 20,620 — Level 2: U.S. government securities 4,505 (17 ) 4,488 — 4,488 Commercial paper 4,959 (5 ) 4,954 — 4,954 Corporate debt securities 30,268 (112 ) 30,156 — 30,156 Subtotal 39,732 (134 ) 39,598 — 39,598 Total $ 69,277 $ (134 ) $ 69,143 $ 29,545 $ 39,598 Stock Warrants All of the Company’s outstanding stock warrants are categorized as Level 3 within the fair value hierarchy. Stock warrants have been recorded at their fair value using either a probability weighted expected return model or the Black-Scholes option-pricing model. These models incorporate contractual terms, maturity, risk-free interest rates and volatility. The value of the Company’s stock warrants would increase if a higher risk-free interest rate was used, and would decrease if a lower risk-free interest rate was used. Similarly, a higher volatility assumption would increase the value of the stock warrants, and a lower volatility assumption would decrease the value of the stock warrants. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s management with the assistance of a third-party valuation specialist. In 2016, in connection with the Investment Agreement between the Company and Acacia Research Corporation (“Acacia”) and the convertible secured promissory note issued by the Company to Acacia (the “Acacia Note”), the Company issued three four-year warrants (the “Acacia Note Warrants”) and a five-year warrant (the “Primary Warrant”). In March 2017, each of the Primary Warrant and the Acacia Note Warrants was amended to provide that the exercise prices thereof shall be equal to the lower of $13.6088 or the Company’s initial public offering (“IPO”) price per share. In May 2017, upon exercise of the Primary Warrant, the Company issued to Acacia a five-year warrant to purchase 809,400 shares of the Company’s common stock (the “10% Warrant”) at an exercise price of $13.6088. At issuance date, the fair value of the 10% Warrant under Level 3 measurement was $5,790. In April 2018, in connection with the advisory agreement between the Company and a financial advisory firm, the Company issued a five-year warrant to purchase up to 20,000 shares of the Company’s common stock (“April 2018 Warrant”). The April 2018 Warrant was fully vested and exercisable upon issuance and has an exercise price of $11.73 per share. The following table summarizes quantitative information with respect to the significant unobservable inputs that were used to value the April 2018 Warrant: April 6, 2018 Volatility 70 % Risk-free rate 2.58 % Term 5 years The following table represents a roll-forward of the fair value of the April 2018 Warrant, which was recorded within other accrued liabilities in the accompanying condensed consolidated balance sheet during the six months ended June 30, 2018: Balance, December 31, 2017 $ — Issuance of warrant 207 Change in fair value 15 Balance, June 30, 2018 $ 222 As of June 30, 2018, the total fair value of the April 2018 Warrant increased by $15 to $222. The expense relating to the April 2018 Warrant has been recorded to general and administrative expense in the Company’s consolidated statement of operations and comprehensive loss for the three and six months ended June 30, 2018. The following table summarizes quantitative information with respect to the significant unobservable inputs that were used to value the Company’s 10% Warrant: May 17, 2017 Volatility 70 % Risk-free rate 1.44 % Discount for lack of marketability 0 % There were no transfers between Level 1, Level 2 or Level 3 financial instruments in the six months ended June 30, 2018.

Stock Plans	NOTE 10. STOCK PLANS 2018 Performance-Based Stock Incentive Plan In June 2018, the Company’s stockholders approved the Company’s 2018 Performance-Based Stock Incentive Plan (the “2018 Plan”), and approved grants of performance-based nonstatutory stock options (each, a “Performance Option”) to the Company’s Chief Executive Officer (the “CEO Award”) and President (the “President Award”), under the 2018 Plan. In May 2018, the CEO Award and the President Award had been approved by a special committee of the Board of Directors of the Company (the “Special Committee”), and the 2018 Plan had been approved by the Company’s Board of Directors, subject to stockholder approval. The 2018 Plan allows the Company to grant Performance Options to its executive officers and other employees as an incentive for them to remain in service with the Company and to further align their interests with the interests of the Company’s stockholders. A total of 4,200,000 shares of the Company’s common stock have been authorized for issuance under the 2018 Plan. The numbers of shares underlying the CEO Award and the President Award are 1,809,900 and 1,357,425, respectively. All Performance Options granted under the 2018 Plan will become exercisable in three equal tranches based on the achievement of specific market price goals for the Company’s common stock. For each tranche to become exercisable, the closing price per share of the Company’s common stock must meet or exceed the applicable stock price goal for a period of 30 consecutive trading days; this is referred to below as the Attainment Date. The exercise price of each of the CEO Award and the President Award is $21.25 per share, which was the closing market price of the Company’s common stock on the Nasdaq Global Market on May 4, 2018, the last trading day prior to the date on which the Special Committee approved such awards (which was not a trading day). Each Performance Option will have a term of ten years following the grant date, subject to earlier termination in the case of cessation of the awardee’s continued service with the Company, as further described in the 2018 Plan. The Company valued the CEO Award and the President Award using a Monte Carlo simulation model. The grant date of such awards for accounting purposes was June 29, 2018, the date that was such awards were approved by the Company’s stockholders. The following assumptions were used in the Monte Carlo simulation model for computing the grant date fair values of the CEO Award and the President Award: Grant date stock price $ 16.82 Dividend yield — % Risk-free interest rate 2.85 % Estimated volatility 73.00 % The fair value per share was determined for each of the three equal tranches of each award and is presented in the table below: Tranche 1 $ 9.22 Tranche 2 $ 10.05 Tranche 3 $ 9.50 The total fair value of such awards is $30,375 and is being recorded as stock-based compensation expense over the derived service periods. At June 30, 2018, the Company had stock-based awards outstanding under the following plans: the 2014 Stock Option/Stock Issuance Plan (the “2014 Plan”), the 2017 Stock Incentive Plan (the “2017 Plan”) and the 2018 Plan.
