Patent Searches

WJH Patent Office usually recommends conducting a patent search at the United States Patent and Trademark Office (USPTO) Public Search Facility located at USPTO headquarters (Alexandria, VA) using an onsite professional searcher to search for granted patents and published applications relevant to your invention. While there are many reasons why it makes sense to do your own preliminary patent searching if you are an inventor, there is simply no comparison between a patent search done by an inventor and a patent search done by a professional searcher.
