Copy rights protection in Bangladesh

Many firms in Bangladesh apply knowledge from one technical domain to innovate in another. This phenomenon is known as knowledge bridging which involves taking knowledge from one domain and reapplying it to another. Or it may borrow ideas and knowledge from several areas and recombining them so as to innovate in yet another area. The knowledge doesn‟t disappear, but nobody knows who the author is. It is on the contrary possesses the synergetic effect. Who is interested in the copy rights protection? To our mind, nobody as there is no any strict law to determine who is the author, inventor of the knowledge. Can it be considered correct? Do we know much about such mechanism? Is it acceptable in the market economy?
