Although you can convert a provisional application into a non-provisional application, the USPTO recommends filing a separate non-provisional application that references the earlier provisional one. Doing so can extend the time your invention is protected by up to one year. A non-provisional application includes a lengthy written document with a description of your invention and all the things you claim you invented, as well as drawings, an oath or declaration and fees for the filing, research and examination of the application. The USPTO recommends using a registered patent attorney to draft and file your non-provisional application. USPTO regulations include specific requirements for the format of applications and the necessary drawings -- and examiners reject applications that don't meet these requirements.What is prior art?
Prior art is all information that has been disclosed to the public in any form about an invention before a given date. Prior art includes things like any patents related to your invention, any published articles about your invention, and any public demonstrations. prior art is "the total body of knowledge, which teaches or otherwise relates directly to an invention. This is the primary criteria in determining the patentability of a new invention. Establishes novelty and unobviousness of the art that relates to the invention in question. Prior art references include documentary sources such as patents and publications from anywhere in the world, and nondocumentary sources such as things known or used publicly."How difficult is a patent search?
Conducting a thorough patent search is difficult, particularly for the novice. Patent searching is a learned skill. A novice in the United States could contact the nearest Patent and Trademark Depository Library (PTDL) and seek out search experts to help in setting up a search strategy. If you are in the Washington, D.C. area, the USPTO provides public access to collections of patents, trademarks, and other documents at its Search Facilities located in Arlington, Virginia. It is possible, however difficult, for you to conduct your own patent search.how do i know if my idea has been patented
Checking to see if your idea has already been invented before applying for a patent saves you time and money. A patent gives you exclusive rights to the product or idea you invented and a way to fight intellectual property theft. The United States Patent and Trademark Office checks your idea against existing patients and pending applications during the application process. Your patent will be rejected if it's too similar to an existing patent, costing you the application fee. While you might find ideas that are similar to yours, you can still patent your idea as long as you show on the application how your take on the patent object is new. You can search for existing patents using various methods, including the USPTO's online database or in person at a field office.Patent Searching 101: A Patent Search Tutorial
Inventors and entrepreneurs who are looking to cut costs frequently want to do their own search. This is a wise first move, but you really need to be careful. It is quite common for inventors to search and find nothing even when there are things that could and would be found by a professional searcher. So while it makes sense to do your own search first, be careful relying on your own search to justify spending the thousands of dollars you will need to spend to ultimately obtain a patent. In other words, nothing in this article should be interpreted as me suggesting that inventors can or should forgo a professional patent search. There is simply no comparison between an inventor done patent search and a patent search done by a pro. Having said that, every inventor should spend time searching and looking if for no other reason than to familiarize themselves with the prior art. Of course, if you can find something that is too close on your own you save time and money and can move on to whatever invention/project is next. Another thing you MUST know about when you use Google Patent Search is that there are also some holes in the database. I have specifically looked for patents I know to exist and cannot always find them. I have heard the same experience from other patent attorneys and agents. Additionally, the most recent patents are not available on Google. What this means is you cannot only rely on Google, but you still must use Google. The Google database covers patents that are issued all the way back to US Patent No. 1. This scope is much broader than either Free Patents or the USPTO . So while you might not find everything, while it is difficult to specifically narrow your search, you still really need to check yourself using the Google database to see if there are old references that might be on point. In this case there are not many to choose from. Many times, however, the list will contain hundreds or even thousands of patents depending upon the popularity of the term or phrase selected. For example, if you search "SPEC/thermos", you will find hundreds of patents that use this word in the specification. In fact, at the time this sample search was conducted (March 16, 2012) no fewer than 970 US patents have the word "thermos" in the specification, and that is only for patents issued since 1976. So what should you do now? If you find too many patents, rework the specification field search. For example, if your search were "SPEC/thermos and SPEC/beverage" you get down to 200 US patents. Ultimately, upon receiving manageable results, just click on several of the patents. The key, however, is to start off broad and then narrow your way down to those that are the most likely relevant references. Also remember that it is critically important to figure out what things are called. I cannot stress this enough. You need to use different names and labels. You will find that patent attorneys typically call certain features by a select few names. These names are not always obvious, but once you figure out what the industry calls something you are far more likely to find relevant patents.
