Inventer is just another spelling for the word inventor, the accepted spelling in United States for anyone who has an idea or invention for a new method, system, device or useful object for consumers.

Any individual who creates or discovers a new patentable device or new method or any other useful means or considerable improvement on any system, etc., is considered an inventer.
Anytime a new, patented product, device, or more effective mode of doing business through a system update is introduced to the public, it touches all of our daily lives. The invention or change can influence how we spend time and money in our businesses, our homes, or how we make the changes that sometimes can hasten the success of our companies.
The rules to obtain a patent are deliberately stringent, complex and steeped in detail to insure the safety of the public, the cost to the consumer and the longevity of the product. The hiring of a patent attorney or agent is key to complying with all of the requests from the United States Patent and Trademark Office to obtain a patent.
Depending on the nature and complexity of the invention in question, the cost could be from $5,000 to $15,000 or, from relatively simple to highly complex as far as billing hours are concerned. If there is a great deal of writing and drawing or interpretation, the costs stated above could change drastically. Legal representatives vary in price, requiring you to shop around for not only reputable representation but also costs your budget can afford.
There are a number of web sites on the computer where you can pick and choose according to the type of representative you require, and cost you can afford. Charges are incurred for each article a representative has to do for you, beginning with a cover sheet and ending with the actual patent application filing. You may have to shop around the many web sites before you decide on someone, preferably in your area.
