Also, how do I find the patent publication number?
If a patent is published, it will also receive a publication number with the following format XXXX/XXXXXXX. On an official U.S. patent cover, the format of the patent number would also have a letter and number at the end, for example: US 7,493,599 C2.
Secondly, what is a wo trademark? A WO patent is granted by the World Intellectual Property Organization, or WIPO. The prefix WO, which is short for WIPO, indicates that the patent will be administered by this body. In general, the protection conferred on an invention by patent law will only extend to the country or territory in which it is patented.
Beside above, what is the difference between a publication number and a patent number?
The application number is assigned when the application is filed at the USPTO. The publication number is assigned when the application is published (usually 18 months after it was filed). It is of the format "2016/0123456". The patent number is assigned if the application is granted.
What does a patent pending number look like?
They typically start with a 2 digit series number, and is followed by a 6 digit serial number. When the 6 digit serial number hits 99999, the series number will increase by one. A provisional patent application number will start with either 60, 61 or 62, and followed by the 6 digit serial number.
