Risks and uncertainties that may face the Company include, but are not restricted to: licensing of the Company's patents can take an extremely long time and may be subject to variable cycles; the Company is currently reliant on licensees paying royalties under existing licensing agreements and additional licensing of its patent portfolio to generate future revenues and increased cash flows; the Company's revenues are subject to fluctuate based on individual licensees' growth and success rates in their respective markets, the impact of seasonality and other market factors on individual licensees' businesses and other factors outside of the Company's control; the Company's revenues can vary significantly from quarter to quarter depending upon the type of royalty agreement with licensees, the timing of royalty reporting by licensees and fluctuations in foreign currency; the Company may be required to establish the enforceability of its patents in court in order to obtain material licensing revenues; changes in patent laws or in the interpretation or application of patent laws could materially adversely affect the Company; a court may determine that certain of the Company's patents are not infringed by certain standards or products or may disagree with management with respect to whether one or more of the Company's patents apply to certain standards or products, which could adversely affect the Company; certain of the Company's patents are, and others may be, subject to administrative proceedings that could invalidate or limit the scope of those patents; the Company will need to acquire or develop new patents to continue and grow its business; fluctuations in foreign exchange rates impact and may continue to impact the Company's revenues and operating expenses, potentially adversely affecting financial results; the Company has made and may make acquisitions of technologies or businesses which could materially adversely affect the Company; the Company may require investment to translate its intellectual property position into sustainable profit in the market; the generation of future V-Chip revenues and the likelihood of the Company signing additional V-Chip licenses could be negatively impacted by changes in government regulation; the Company is dependent on its key officers and employees; the price of the Company's common shares is volatile and subject to market fluctuation; and the Company may be negatively affected by reduced consumer spending due to the uncertainty of economic and geopolitical conditions.
