Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Resonant Inc. is a late-stage development company located in Austin, Texas, with offices in Goleta, California, Burlingame, California and Anyang, South Korea.  We were incorporated in Delaware in January 2012 as a wholly owned subsidiary of Superconductor Technologies Inc., or STI. Resonant LLC, a limited liability company, was formed in California in May 2012. We changed our form of ownership from a limited liability company to a corporation in an exchange transaction in June 2013, when we commenced business. We are the successor of Resonant LLC.  We completed our initial public offering, or IPO, on May 29, 2014. On July 6, 2016 we acquired all of the issued and outstanding capital stock of GVR Trade S.A, or GVR. GVR is a wholly owned subsidiary of Resonant Inc. The company operates in one market and segment, the radio frequency filter design industry.
    The innovative software platform we continue to develop is based on fundamentally new technology that we call Infinite Synthesized Networks®, or ISN®, to configure and connect resonators, the building blocks of RF filters. Currently, we are leveraging ISN® to develop designs targeted for either the Surface Acoustic Wave (SAW) or Temperature Compensated, Surface Acoustic Wave (TC-SAW) manufacturing processes. We also enabled ISN® for BAW designs, which has resulted in our invention of a novel resonator structure based on a combination of interdigital transducer (IDT) and piezoelectric layer, XBAR®, which exhibits performance parameters suitable for 5G,5-7GHz WiFi and UWB applications - high frequency operation, large bandwidth and high power reliability.     
Using ISN® we have developed an IP portfolio of more than 300 patents filed or issued, with more than 150 filed or issued targeting XBAR®, 5G and high frequency WiFi applications. In addition, with continued requirements for increasing numbers of filter designs our innovative software platform addresses the need for increased designer efficiency, reduced time to market and lower unit costs in the designs of filters for radio frequency, or RF Front-Ends for the mobile device, Customer Premise Equipment (CPE) and Infrastructure industries.  The RF Front-End, or RFFE, is the circuitry responsible for analog signal processing and is located between the device’s antenna and its digital circuitry.  Filters are a critical component of the RFFE used to select desired radio frequency signals and reject unwanted signals.
    We believe licensing our designs is the most direct and effective means of validating our IP and IP related libraries and demonstrating the power and accuracy of our ISN® multi-physics EDA platform.  Our target customers make part, or all of, the RFFE.  We intend to retain ownership of our IP, trade secrets and designs, and we expect to be compensated through license fees and royalties either prepaid at contract inception or based on sales of RFFE filters that incorporate our IP, trade secrets and designs.
Capital Resources and Liquidity
    As of December 31, 2020, our accumulated deficit totaled $150.9 million. In the year ended December 31, 2020 our net loss totaled $28.4 million and we used $23.2 million of cash and investments for operating activities, the purchase of property and equipment and expenditures for patents. To date we have not generated significant revenues to enable profitability. We expect to continue to incur significant losses. These factors raise substantial doubt regarding our ability to continue as a going concern. At December 31, 2020 we had cash and cash equivalents of $25.0 million. Subsequent to December 31, 2020, but prior to publication of the financial statements on this Form 10-K, we raised $4.1 million of cash from sales of common stock using our At-The-Market Equity Offering Sales Agreement. In the absence of a significant revenue increase we project these cash resources will provide sufficient funding into the first quarter of 2022. We are subject to the risks and uncertainties associated with a new business. We have also been impacted by the COVID-19 pandemic which has added additional risks and uncertainties. Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts and entering into new customer contracts, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. We may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness. There can be no assurance that additional financing will be available to us on acceptable terms, or at all in which case we might be forced to make substantial reductions in our operating expenses which could adversely affect our ability to implement our business plan and ultimately our viability as a company. Even if available, such capital may be dilutive to existing stockholders. The accompanying consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.
