Name Street State City Local No. majority of instances, the inventor is usually financially irresponsible, and so his agreement to protect the purchaser against such legal risks may prove of no practical value; for such suits are usually filed against the more substantial party, who is the true infringer, anyway, and who may be unable thereafter to reimburse himself for any such loss from the penniless inventor. Also, when operating under a license, it often limits the inventor's liability, as to an amount equal to the total royalties previously paid; and this might be far less than the amount of profits and damages awarded the owner of the patent which is infringed, and so obligate the purchaser to pay the excess. Requires Skilled Attorney An infringement investigation and report requires the utmost of painstaking work by a skilled patent attorney. He must first find all the patents issued during the past seventeen years on inventions like or near the inventor's, and then carefully read every claim of these patents on the invention, to determine which ones may be infringed. Where any such infringement appears to exist, the attorney then obtains and studies the file history of such infringed claims to determine their validity and scope that is, whether or not in case of court action, such claims would be held to be both valid and infringed. While the cost of an infringement opinion, particularly if the prior art is voluminous, or the subject matter highly technical, may amount to thousands of dollars, in an average case involving a simple invention the fee should be from $250 to $500. So there is no real reason why anyone purchasing any interest in a patent right should not first take this very necessary precaution, not only to determine the right to use the patent after spending his money for it, but also to eliminate the risk of having to pay heavy profits and damages in the event of a later decision against him. Represent Insurance Protection Such searches, then, are not only necessary preliminary steps before purchase or license of patent rights, but they moreover represent highly essential insurance protection against the possibility of large business and financial loss occasioned by the innocent infringement of the patent rights of others. Then, too, if this step is taken in time, and before the invention appears on the market, it often happens that any patents which may be infringed can be acquired or licensed under for a nominal sum, and before their owner learns of the value and importance of such rights to the purchaser or licensee of the later invention.
