Sony seems to have become just a tad forgetful in the matter of trademarks. Just a few weeks ago they lost "The Last Guardian" due to forgetting to request an extension of the deadline for the filing of a statement of use.

The same just happened yesterday with Bloodborne and a few other trademarks previously held by the house of PlayStation in the United States. here's a list.

Basically, every six month after the registration of a trademark, if a company still hasn’t provided proof that said trademark is being used in commerce in the country where it has been registered, an extension has to be requested, or the mark is canceled. This can be done up to five times before the mark is lost.

If the extension isn't requested, the mark is lost as well, and this is exactly what happened with Bloodborne and the rest of the bunch listed above.

Of course Sony can just file for a new registration, or request a reinstatement of the dead trademarks, but it remains hilarious that they keep forgetting to do the maintenance of their trademark portfolio.
