Should an inventor defer the filing of his application until his invention is fully developed as regards the detail construction and arrangement of the parts? The best opinion seems to be in favor of the prompt filing of the application. The final form of the details can best be determined by the manufacturer and expert machinists and designers, who appreciate the matter of economical manufacture, which is quite as essential as the efficiency of the device or machine. Clearly, therefore, the inventor cannot decide as to all the details; why then should he delay his application?
The safest course for an inventor is to file his application for a patent as soon as his invention is complete in its principal features, so as to conform to the requirement of the Patent Law that an invention be sufficiently complete to be theoretically operative. The mechanical details are rarely of great importance as far as the patentable fea[p. 25]tures of the invention are concerned. Still, it is well to give the attorney full particulars of whatever details the inventor has in mind.
Exhibit of the Invention.
Under the security thus afforded for the main features involved in his idea, the inventor can proceed more deliberately in perfecting and improving his invention, and can then file an additional application if necessary, to secure special protection on particular improvements or the improved invention as a whole. The early filing of an application may turn out to be important in securing to the inventor his right of priority. When the inventor comes to exhibit his invention, with the idea of bringing it to the attention of the public in general, there is no question that he should then have his invention in the best form he can, and in as attractive shape as possible.
To Avoid being "Squeezed."
The patentee who proposes to realize from his invention should never let it be known that he is in want; of course, in some cases he cannot help himself, but he should endeavor to obtain the necessary assistance from his acquaintances, and under no circumstances let those with whom he is trying to deal get an insight into his financial condition, as capitalists and others will very often take the advantage of an inventor when known to be in straitened circumstances, and the patentee probably would[p. 26] not realize as much from his patent as he otherwise could. Therefore, it is advisable in all cases for the patentee to manifest no impatience, remain silent as to his financial condition, and strive to impress those with whom he is dealing that he is in no condition to be "squeezed."
Value of Record of Invention.
Inventors, while working on a complicated machine, should not overlook the value and importance of keeping a record of the progress of the development, illustrating it with sketches, signing and dating them with each new addition, and, when practical, having it witnessed by one or more persons. This plan is preferred by many inventors to filing a caveat. Such a record will be found very valuable in case of an infringement, as it enables the inventor to ascertain the various steps of his invention, and is a sort of evidence that cannot be impeached. Such a record of a complicated invention, when the inventor has put much time and study upon the subject in perfecting it, will also be found valuable in effecting sales, and in fixing the price of the patent.
Prejudice against Patents.
It cannot be denied that at the present time there seems to be in many sections of the country a strong prejudice against patents, which sometimes makes it difficult to get people sufficiently interested to take hold of any patent; especially is this true[p. 27] when the patentee endeavors to sell his patent piecemeal; that is, by county, township, shop, or farm rights. No matter how important or valuable the invention may be, there seems to be a disposition on the part of the public to look upon such rights as a fraud, and to be very cautious how they invest in them.
