Q: how to find Law Firm who wrote the Patent"
The name of the firm that is on the issued patent is not always the firm that wrote the patent application as sometimes the patent application moves from one firm to another during the time that the application is pending (such as when a company is sold or even when just the patent application is sold or licensed).
The USPTO allows anyone to look at all the documents associated with the process of seeking a granted patent or a published patent application. So go to https://patentcenter.uspto.gov/ and enter the patent application number or the issued patent number and you can see the transmittal paperwork for the original application which will indicate the attorney that filed the application.
A: If you're looking to find the law firm responsible for drafting a particular patent, start by examining the patent's face page. Often, the patent attorneys or agents responsible for the application are listed there. If that doesn't provide the information, you can check the United States Patent and Trademark Office's (USPTO) online database, known as PAIR. Within PAIR, you can access information about the prosecution history of the patent, which may reveal correspondence between the USPTO and the law firm. Another option is to directly contact the patent owner or inventor; they would likely have records or knowledge of which firm they engaged. Lastly, larger firms often tout their successful patent applications, so a quick search of their websites might yield results. Remember, patience and persistence are key in such investigations.
