I Having completed an invention, and found it to answer all ?the anticipations entertained previous to its completion, in ventors next turn their attention to securing a patent If I their application is allowed, they are in a position to realize solid returns for time and money expended i In doing this they find that perfecting an invention, and I making money out of it afterwards, are two very different : things However great may be their inventive talent, it avails , nothing in the business management, which must be conduct ed wisely or financial success will not follow At this stage of their operations they are apt to suppose i that they must in some way secure the aid of outside capita], and many are led to sacrifice a large share of a valuable mojnopoly, to secure a small sum of money, and the help of what they suppose to be an expert in business Ten to one they fall into the hands of some shark, who devours the profits of t their invention, secures final control of it, and leaves them I out in the cold Few inventions are made that cannot be disposed of by the L inventor as well as any one he can employ or take into partt nership with him If of a small and cheap kind, and the best ; way to make money is decided to be by manufacturing and selling the article rather than rights to make it, let the in ventor be content to begin small, gradually increasing his ibusiness from his profits, until it by natural and healthy growth arrives at the point where large returns may be ex ? pected There are, however, some inventions that can only bo worked profitably with large capital, and an inventor may bo so placed that his only means of obtaining the necessary aid is to put in his patent against capital as stock in a jointstock company In making an arrangement of this kind, the inventor should act only under the counsel of a competent legal adviser The money expended in obtaining such counsel ?will never be better expended A joint stock company hasins and outs in its organization which are difficult for the uninitiated to comprehend ; and many an inventor has been in ! veigled into an arrangement whereby he has been shorn of his rights, and has found out too late that he has been fleeced Were inventors to dispose of their property in improvements as carefully as they deal in real estate, and proceed as cautiously in the transaction of their business as they should, we should hear less about capitalists reaping where they have not sown, while the simpleminded man who has put the power to make money in their hands is neglected and unrewarded In the sale of rights an inventor will generally succeed better than any agent he can employ He understands his invention, and what a man understands well, he can, as a rule, talk well But in the sale of rights there is generally more or less barter, a Yankee way of dealing, which gives considerable scope for sharp practice, and an inventor who is not on the alert, is often sold himself while he thinks he is making a good bargain In this, a good judge of the value of all kinds of property has an advantage Inventors, therefore, who propose to sell rights, should first post themselves in regard to the value of most kinds of property likely to be offered in exchange for rights, and where it can be most iadily put into market and turned into money All the time he spends in obtaining such knowledge, will largely repay him when he comes to apply his knowledge in selling his patent He should insist upon all agreements being made in legal form, and omit no technicality likely to secure him from trouble in the future In short, he should be thorough and exact in all his transactions, and if he has really got a valuable improvement, he can scarcely fail to make money
