One of the main things to do when commercially feasible ideas hit the brain is to look for patents with that concept. The patent allows the conversion of the concept into a business and prohibits others from infringing on that idea. In general, patent search by a patent search organization requires footwork and money.
However, due to the onslaught of the Internet, several free patent searches are available. A free patent search is made by search engines and includes a database containing all patents applied during the past few years (generally within the patentable term meaning 20 years in the United States). Past inventions are carefully documented, and photographs and functions are described as necessary. When a keyword is entered in the search bar, a search that triggers a given similar conceptual patent is triggered. It is important to enter related keywords. This will affect the results of the search. It is recommended to search using different keywords.
Normally, the free patent search site contains all documented information on US patents (available from USPTO) and European patents (Esp @ cenet). However, there are many websites containing patent information of other countries. Before punching the keywords, the searcher must click on the appropriate country tab.
The reason why the free patent search site is exaggerated is the enormous workload that the national patent office faces each year. Each country's patent office also offers its own free website to search for patents to reduce workload. Most ideas that claim to be original are sandwiched between buds when similar concepts are found.
The current trend is to first search for a patent on a free search engine. If a patent is not found, we will approach the patent attorney for legal work. Lawyers look for patents on free search engines before accepting the case.
http://www.freepatentsonline.com is a popular free patent search site with more than 300,000 US and UK patent databases. As more and more patents are awarded, the site is constantly being updated.
