A 2010 patent shows a WIPO filing and granted EP patent, but no US mark. Does that mean the patent was not granted or pursued in the US?

Question

I am trying to understand WIPO filings. It appears that they give the right to file patents in multiple countries more easily, but don't constitute an international patent. If a WO numbered patent with EP granted status does not show a US patent number, does that mean the patent was not issued in the US as well. The EP patent was granted in 2010, does that preclude now filing in the US? Thank you! https://patents.google.com/patent/WO2010012434A1/en

Answer 1

The time window for entering into the US national phase is long gone and the applicant did not enter it so no protection for that invention is possible now in the US.

As for the European patent, it was granted on September 2016 but it was directly filed as European patent, i.e. it is not the entry into the European regional phase from the PCT. A non-exhaustive list of countries where the European patent has been validated and is in force can be found here. Protection conferred by the European patent only exists in those countries where the validation formalities have been completed and the respective annuities are paid every year.

In the first link above you can review the prosecution history of the European patent, including the possible existence of oppositions to the European patent (none filed in this case).

Answer 2

There is no such thing as an international patent. Every location has its own patent laws including its own methods of enforcement. A PCT application, administered via WIPO, is an application simultaneously to about 150 jurisdictions. After 30 months (31 in some places and somewhat extendable in some places) it is too late to continue the applications into the National Stage in specific places.
