About Us

Integrated Surgical Systems was incorporated in Delaware in 1990 and was founded to design, manufacture, sell and service image-directed, computer-controlled robotic software and hardware products for use in orthopedic surgical procedures. On June 28, 2007, the Company completed the sale of substantially all of its assets. After completion of the sale, the Company became inactive, and it is no longer engaged in any business activities related to its former business described above.

On June 28, 2007, the stockholders approved the liquidation of the Company if the Company was unable to complete an acquisition or similar transaction within one year of the sale of its assets.  With this approval, the stockholders also granted the Board of Directors the authority to delay, revoke or abandon any decision to liquidate without further stockholder action if it determined that the liquidation was not in the best interests of the Company or its stockholders. The Board of Directors has determined that it currently is not in the best interests of the Company and its stockholders to liquidate the Company. The Company’s current operations are limited to raising additional funds to be used to maintain the Company’s public company status and to complete a business combination or strategic alliance, if suitable candidate(s) are identified.

On April 20, 2011, the Company purchased 363,636 shares of common stock of ClearSign Combustion Corporation, a privately-held Washington corporation (“ClearSign”), for an aggregate purchase price of approximately $1,000,000, or $2.75 per share, in connection with ClearSign’s private offering of up to $3,000,000 of its common stock. Due to a 1.25-for-one stock split, which occurred subsequent to this purchase, the Company now holds 454,545 shares of common stock of ClearSign at $2.20 per share. ClearSign is an early-stage clean energy company focused on developing technology to increase energy efficiency in most types of industrial combustion systems.
