CPVD owns valid and expired patents in the U.S. and other number of countries. CPVD believes that its patents still represent an important and valuable
asset, even the expired patents, because the limitation period for patent infringement litigation is 6 years after the patent holder becomes aware of an
infringement. Due to insufficient resources CPVD has not been able to pursue potential infringements in an appropriate manner.During the last years the U.S.
jurisprudence acclaimed increasingly the value and justification of intellectual property. This development seems important for CPVD in its willingness to
protect the rights of the Company's shareholders.

Consequently an increasing number of law firms are willing to cooperate on a contingency basis. CPVD believes that its video data compression is valuable,
possibly comparable with compression formats like JPEG. The management and Board of Directors is prepared to cooperate in 2005 with experienced
partners and law firms to enforce the rights of CPVD’s shareholders.CPVD considers the following owned and maintained patents important for the
shareholder value:
