GVR is a wholly owned subsidiary of Resonant Inc. Using our innovative software platform we have developed an IP portfolio of more than 200 patents filed or issued, with more than 40 filed or issued targeting XBAR technology, including application to 5G. 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 industry. The RF front-end, or RFFE, is the circuitry in a mobile device responsible for analog signal processing and is located between the device’s antenna and its digital circuitry. The 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. Filters are a critical component of the RF front-end 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 ISN^®platform and related IP libraries. Our target customers make part or all of the RFFE. We intend to retain ownership of our designs, and we expect to be compensated through license fees and royalties based on sales of RFFE filters that incorporate our designs. Capital Resources and Liquidity We use the net proceeds from the sales of our common stock for product development to commercialize our technology, research and development, the development of our patent strategy and expansion of our patent portfolio, as well as for working capital and other general corporate purposes.

At September 30, 2019 and December 31, 2018, we had incurred accumulated losses of $114.6 million and $92.6 million, respectively. The losses are primarily the result of research and development costs associated with commercializing our technology, combined with start-up, financing and public company costs. We expect to continue to incur substantial costs as we continue to engage customers, increase the number of devices under design and build the infrastructure to support our anticipated growth. Our condensed consolidated financial statements account for the continuation of our business as a going concern. We are subject to the risks and uncertainties associated with a new business. Our principal sources of liquidity as of September 30, 2019 consist of existing cash and cash equivalents totaling $14.7 million, which includes approximately $9.9 million in proceeds from our private placement of common stock that closed in September 2019. In the first nine months of 2019, we used approximately $17.9 million of cash and investments for operating activities, the purchase of property and equipment, and expenditures for patents. Due to these conditions, along with anticipated increases in expenses, substantial doubt exists as to our ability to continue as a going concern. After evaluation of these conditions, we believe our current resources, along with expected proceeds from forecasted billings, will provide sufficient funding for planned operations into June of 2020.

We have a Form S-3 universal shelf registration statement on file with the SEC. The universal shelf registration statement on Form S-3 permits us to sell, in one or more public offerings, shares of our common stock, shares of preferred stock or debt securities, or any combination of such securities and warrants to purchase securities, for proceeds in an aggregate amount of up to $50.0 million, subject to potential limitations on the amount of securities we may sell in any twelve-month period.
