Patent Drafting: What is the Patentable Feature?
Due to the laws of nature, and the reality that there are only a finite number of solutions to any particular problem, every generation invents, or re-invents, many of the same things. Thus, it is always wise to do a patent search to start the process. I guarantee a patent search will uncover inventions that you did not know were out there. With over 8.5 million utility patents having been granted in the U.S. and well over 1 million pending patent applications, and millions of other published but abandoned patent applications there is always something that can be found that at least relates in some ways. You are always better off knowing about those related inventions. This allows you to determine whether moving forward makes sense, and it also allows for a patent application to be written to accentuate the positive, and likely patentable, aspects of an invention.
