Thank you for your interest in the services of Patent Search International. We are extremely pleased to have the opportunity to be of help to you toward the possible patenting and development of your idea.

We have posted (AS SAMPLES) our four page form which includes your record of invention, as well as our statement of confidentiality and non—use. These forms can be easily downloaded. These forms can also be mailed to you when you visit Send Info Page and fill out address form. The first step in processing an invention, and one which can not be circumvented, is to conduct a preliminary patent search. Upon receipt of the completed form, we will conduct a search of the United States Patent Office records in order to ascertain whether or not your idea is new and patentable. Within seven to ten days, we will send you those patents that we have found to be similar to your idea, along with the opinion of an independent registered patent professional as to whether or not your invention is patentable.

Along with your completed form, please send us your check in the amount of Two Hundred Fifty Dollars ($250.00) for payment in full of all the above-mentioned services. We also accept Master Card, Visa, Discovery & American Express.

We are looking forward to receiving your record of invention authorizing us to proceed with the preliminary patent search, the first all important step in the development of your idea.

Helping thinkers become doers.
