Since a very small number of inventions succeed financially, despite attempts to market them, a large number of inventive people prefer to purchase a service that is fixed in cost, limited in risk, and gives them the satisfaction of attempting to gain attention for their invention. The question of inventing something new is just one of the many risks facing inventors. ISC generally must rely on the inventor to do their homework and ascertain what is new, or not. No company on earth could possibly track or be aware of all the new products that exist. There is no official record of such products in a central location nor is there any computerised database to search.
New products come and go.
What was new in 1920 may have failed as a product but could be successful in 1995. Some products are successful in one geographical area, but not another. There are too many different industries and too many nations in our world of five billion people for anyone to actually know for a fact what is new and what is not. ISC have learned this from actual experience. Many individuals bring ideas to us which they believe to be novel or new.
