For inventors and owners who have received, from a foreign (non-U.S.) patent office, a notice of patent allowance or a final ruling allowing at least one claim, there is a process for fast-tracking any corresponding U.S. patent application. This is called the “Patent Prosecution Highway” (“PPH”). The PPH is an international treaty-based arrangement between the […]

Here is a quick rundown on the differences and why they matter. Generally speaking, the filing date of a patent is the […]
