Patents are valuable - Patents may have commercial value but that usually depends upon how it has been used. A patent means the invention works as verified by the government - The U.S. government does not test inventions to see if they work. A patent gives the owner the exclusive right to make, use, and sell the invention - A patent gives its owner the right to EXCLUDE others from making, using, and selling exactly what is covered by their patent claims. A holder of a prior patent with broader claims may prevent the inventor whose patent has narrower claims from using the inventor's own patent. A patent right is exclusory only.What Does New or Novelty Mean?
In order for an invention to be patentable it must be new as defined by patent law . An invention cannot be patented if: The invention was known or used by others in the United States, or patented or described in a printed publication in the United States or a foreign country, before the current applicant filed for his or her patent. Someone else has made the same invention as you did. The invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country more than one year prior to the application for patent in the United States. You or somebody else revealed your invention more than a year ago to the public.Utility patents
Utility patents are for either a: process, machine, article of manufacture, composition of matter or an improvement of any of the above. Patent protection is also available for (1) ornamental design of an article of manufacture (design patent) or (2) asexually reproduced plant varieties by design and plant patents (plant patent).patented invention
When you conduct the online patent searches, you'll be able to read the full text of the patents and see diagrams. Don't be discouraged if you do find your invention idea is already patented. You may be able to come up with a variation that's not patented...And double check the patent. Sometimes, what looks like the same invention idea may actually be quite different. Some of the free searches may not involve a complete search of all granted patent archives and patent applications for all time. You may want to consider hiring a registered patent attorney to find this information for you.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.
