Patent Attorney Directed Search
Going through a lawyer to search patents will cost the least amount of time and the most money. Patent attorneys employ professional researchers. You hire the attorney, and the attorney gets someone to conduct the search. Then the attorney adds a mark-up to the search bill, sometimes as much as several hundred percent. Many lawyers cloak this in the term handling fee. To save this extra expense, some inventors hire their own researcher or do the search themselves. Most patent attorneys don't render an opinion based on a search conducted by anyone other than their own searcher. However, you can tell a lawyer that if they won't accept the work of your search firm, or searches done by yourself, you will go elsewhere where such work would be acceptable. If you're paying the bills, and you're willing to take the risk, the lawyer shouldn't have a problem. Now, if the search results show no prior art in my field of invention, you don't need an attorney to tell me the coast is clear. Conversely, if a search reveals prior art that's spot on your invention, you don't need an attorney to tell me my idea has been done before. You might, on the other hand, hire an attorney to help end-run an existing patent through the use of language in the application. If you hire a lawyer, get a quote in advance. The fee will be based on how all-encompassing you want the search to be.What Is A Patent?
It is just like a property right for the inventor. All U.S. patents are issued by the United States Patent and Trademark Office or USPTO. Most patents last for twenty years. The twenty years begins on the date the application for a non-provisional or provisional patent was first filed. A patent gives you the right to exclude others from making, using, offering for sale, or selling your invention in the United States or importing your invention into the United States. Once a patent is issued, it becomes your responsibility to enforce the patent, the USPTO will not enforce your rights for you. From the USPTO you are only granted rights that are honored within the United States, U.S. territories, and U.S. possessions.More on Prior Art
Remember, while patent searching is a big part of prior art , it is not everything. If someone has made your invention before you without patenting that still counts against your patentablity. A complete search for prior art might include for example: searching non-patent literature such as any magazine, newspaper, or trade paper article written about inventions like yours also a complete search would include international patent documents (online) and not just those found at the USPTO. Do not make the mistake of believing that just because no one else is selling your product that it does not already exist. After determining that your idea is patentable and qualifies for a patent - you now need to decide if the expense of patenting is worth it.Attorney Fees / Invention Complexity
The USPTO, IP Watchdog and every patent law firm strongly recommends that inventors hire a patent agent or attorney to prepare the application. IP Watchdog reminds inventors that not only is the process confusing, but a patent is a legal document that uses the language found in the application and patents can only be protected in court, where every word in the document matters. IP Watchdog reports that the median cost of a patent attorney is around $250 an hour, higher in urban areas (Quinn suggests hiring an experienced attorney that works in an area with a low cost of living as a way to control costs, as opposed to hiring an inexperienced attorney). Quinn states that, depending on the complexity of the invention, attorney fees for conducting a search and preparing an application with drawings usually run between $7,000 and $15,000. The more complex an invention, the longer the attorney spends researching related patents, writing up a detailed description and outlining exactly what the patent should protect. Drawings also take longer the more complex the invention is, and USPTO rewrites can be more difficult.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.
