The U.S. Patent and Trademark Office in Crystal City has recently acquired a "Video Patsearch," a new type of computer especially designed for patent search work.
The computer is a gift from Intellectual Property Owners Inc. and is manufactured by the Pergamon International Information Corp. in McLean.
The computer shows the first page of drawings and the first page of the specifications of 750,000 U.S. patents granted since 1971. This information is retrieved from the computer by entering certain keywords, such as the patent classification or the title of the patent.
Computer operators will be provided for patent searchers. The cost of using the computer is $1 a minute.
While this new computer will unquestionably speed up patent searching in many cases, it does have certain disadvantages. Unfortunately, it will not show foreign patents or any patent issued prior to 1971. In addition, it will show only the first page of drawings and none of the claims on a patent.
